Make your own stakebox. Ultimate beginners guide how to compile any wallet on AARCH64 (Raspbery pi and other SBC)
I contemplated to wrote this for a long time, so it's finally time. As you know a lot of altcoins uses PoS (Proof-of-stake) way of "mining" coins. Which basically means, that you hold coins on your unlocked wallet and you are receiving stakes as a reward. This requires very little power and it can bring you a lot of rewards, at just 10W from the wall. So first I am using latest Raspbian on RPI4B 4GB in this example.Setting up Raspbian is not part of this process since it's very well documented. I recommend to change user from pi to something else due to security concerns and you can also do other stuff just search "security Raspberry PI" and you find a lot of articles, but this is not the focus of this guide. I know there are a lot of guides on the internet, but I am using like 5 sources, so it's compiled what other people wrote and some of my research. I am using AnyDesk insted of SSH or VNC server, because it works it's ligthweit and it just works. So after you see the gui of Raspbian, just launch terminal (CTRL + ALT + T) and do basic thing: sudo apt-get update && sudo apt-get upgrade Than press Y and let it run, after is finished, we need to prepare so dependency packages. Since most of the wallets using Berkeley DB 4.8 we need to obtain it. So in terminal wrote:
cd cd Downloads wget http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz tar -xzvf db-4.8.30.NC.tar.gz cd db-4.8.30.NC/build_unix ../dist/configure --enable-cxx make sudo make install
So wait unti it's finished and than you can delete files in Downloads folder in gui or use:
Watch the output folder which it creates, it's stated in the first two lines and copy then by highliting the text and CTRL+SHIFT+C copy it to your clipboard.
cd Streamies (this is that git created folder) ./autogen.sh ./configure CPPFLAGS="-I/uslocal/BerkeleyDB.4.8/include -O2" LDFLAGS="-L/uslocal/BerkeleyDB.4.8/lib" sudo make (this could take hours) sudo make install
And you are done, files is going to be in folder /uslocal/bin (DO NOT delete git created folder, because you are going to need it for faster compiling, when wallet get's and update.)
Now you can list files by:
And then you can copy/move them where ever you want by using:
sudo mv * [destination full path]
Let it run and go back to folder where you move those files.
sudo chmod +x streamies-qt (since we want to run wallet)
In most cases compiled files are going to in format of "shared library" so we need to create script to run it. Open up a text editor from gui or through nano. And paste this to that file:
And save it as a sh file, for example run.sh. Then we need to make it runnable so:
sudo chmod +x run.sh
Now to run it, it's just:
And here we are glorious GUI wallet appears and you are done, you can paste blockchain, wallet.dat from other sources, so this migration is pretty easy and you, if you have it on for exaple flash disk. So this is basic how to compile QT wallets on AARCH64. I am running 7 wallets, 2 of those are Masternodes and RPI 4B 4GB would handle way more, I am at best on half of my RAM. Some wallets need more package, but it's not much of and issue, since compiling stops and you just copy paste nape which is missing put it in the google and add "apt-get" after the name of package and you are going to see, what is the name of the packages so it can be retreived from package assinstant aka apt-get. So basically:
sudo apt-get install [package name]
Then press y and again wrote:
This process is going to continue where it was left off, so nothing is going to run from beginning. Updating wallets is basically exactly same, just repeat steps from "git clone" and after that proceed as it was written above. So I hope this helps some of you, to use this at home and not on some VPS, if you are anxious as me, to host my wallets on remote server.
I have been trying to install Electrum 3.3.8 in Ubuntu 16.04 and ran into some issues with python etc. I opted out and just downloaded the app image , that seemed to work fine. I went ahead and deleted the app image and all folders to try and go back to install for Linux. please take a look at the screen shot and let me know how i can delete this Electrum Bitcoin Wallet shortcut which does execute anything. https://preview.redd.it/q04tfu3l3n151.png?width=1360&format=png&auto=webp&s=a3857c99f69fa8b58aeb39507d70611288406b70 Once i can delete this shortcut i will go back and try to install for Linux as appose to just the app image.
The abbreviated name of Tkey Messenger is tkey.me. First of all, TKEY-ME is a secure messenger with p2p audio and video calls, and in the future, a built-in digital wallet.
“Every day we communicate in messengers. We earn money at work. We make purchases and transfers. We are here to combine these processes in one application and make sending funds as easy as sending a message”
The Tkey Messenger as a new ecosystem
Do you think we are here to compete with other messengers? — No, there are a lot of great messengers. We are here to create our ecosystem and the internal market in it. Combine these processes in one application and make sending funds as easy as sending a message. After all, we work in the field of FINTECH, cryptography, and blockchain, why not apply the best practices and knowledge in practice? Therefore, the TKEY Messenger should be considered for a large ecosystem. This is a new payment segment that covers fast communication tools in combination with an internal payment system, a set of exchange practices, blockchain, cryptography, our own experience, and the experience of global companies.
You or your relatives live abroad and you want to send funds quickly, for example, 2600 USD — you just open a chat with your loved one, send a message and 2600 USD in the same second become available on your loved one’s account. https://preview.redd.it/nmz4ienrue651.png?width=697&format=png&auto=webp&s=c3902fc0df1ed2eba425c3f3db3eb8c40bc7a237 It turns out that you can exchange Tkeycoin for USD, EUR, or GBP in a matter of seconds, as well as instantly send them to any place in the world and without hidden fees, the exchange amount is immediately available on the screen. Or you have Bitcoin, and the Recipient needs dollars — Tkey Messenger will take care of all the complex tasks, you will only need to send a message to make the payment.
Each completed payment will be processed through adigital payment systemwithout Bank intervention. You can link your Bank card to automatically withdraw digital funds to your local currency.
“Moving money around the world should be as easy and cheap as sending a message. It doesn’t matter where you live, what you do, or how much you earn.”
Send TKEY or Bitcoin via message, has it become a reality?
In Tkey Messenger, you will be able to quickly send digital currency using a message. You can not specify a public address, but send a digital currency using a message.
Instantly send funds to friends or relatives anywhere in the world. No Bank, no problems, no hidden fees.
Top up your mobile phone or pay for the Internet?
The usual payments, such as the Internet or mobile payments, will certainly be available, because if we can transfer pounds from England to Canada in a matter of seconds, and the recipient will receive dollars, why can’t we make a payment for the Internet? “Of course you can.
What do we get in the future when using a Tkey Messenger?
We get an ideal payment system with instant transactions, fast access to various currencies, including digital, instant international payments, a huge platform for business, a marketplace with trusted sellers, secure transactions, while fast communication, p2p calls, and video communication. Not to mention various chips, in the format: cashback, savings account, invest. products, etc.
International transfers without Commission and in seconds;
Instant account opening — just create an account to get access to payments;
Access to funds 24/7/365 wherever you are.
Multi-currency wallet — you can use both digital currencies and classic currencies, such as the pound, euro, and dollar.
Payment in digital currency anywhere in the world.
The mobile Finance industry is developing rapidly against the backdrop of a growing number of Internet users and the increasing role of smartphones in modern life. Today, the mobile device market attracts about 2 billion people, who remain passive players in financial markets.
With the Tkey Messenger access, you always get access to instant Finance, shopping, and the nice things you want to get here and now. In practice, it has turned out that we can often forget the keys to the apartment, rather than the phone, so your finances will always be with you.
The Tkey Messenger version 1.0.0 is the core that opens up new features that we discussed above, payments, and more. Now it is a convenient and stylish messenger with an intuitive design, instant messaging, and secure audio and video communication.
The P2P audio and video calls in a Tkey Messenger
When creating the first version, we focused on high-quality video and audio communication. Now you can easily call by video and be sure that you will get a high-quality video stream, as well as the absence of restrictions from third parties because the connection is carried out on the principle of p2p.
Audio and video calls are made in p2p mode, so there is no recording of calls at all.
The web version of Tkey Messenger is available at → http://web.tkey.me/. The web version has full call functionality, so you can easily call through it, both via video and audio. Video calls are available with the “Share” function, you can easily “share” your screen for the interlocutor and show what is happening on it. This function can be used for presentations or training events.
Screen Sharing is a demonstration and broadcast of the screen. “Share” your screen for the interlocutor and show what is happening on it.
In the web version, you can launch a group video call. In the chat, tap the “handset” icon — the call will be sent to all participants in the chat, so all participants in the group chat can hold a video conference of up to 50 people. The user can turn on the camera and not turn it on, but simply participate in a video conference via audio.
On average, messengers that support the function of video calls in high quality, hold a video stream of no more than 8–10 people.In a Tkey Messenger, group conferences support up to 50 people. Soon-public online broadcasts and streams.
The first version only supports private chats and group chats. Group chats are also completely private, so there is no “Share” function, only the chat participant can invite another participant to the group chat.
Create your thematic chats. Work. Family. Friends. Be the first while we develop. Soon-public channels and chats.
Each participant, when they click the “Exit and delete” button, deletes messages and information from the chat on their side. In group chats, all information is deleted by the last person to leave the group chat. After deleting-all messages, media, photos, and other data that were in this chat are automatically deleted. If all participants leave the group chat, it will be automatically deleted, and all information published in the group chat will also be deleted.
The chat between the two parties
This is a classic private chat between two participants, instant messaging, sending media. The rights of the participants are equal. Any chat participant can delete the entire chat. after deleting all messages, media, photos, and other data that was in this chat, it is automatically deleted.
Our developers do everything to make Tkeycoin products as clear and convenient as possible for our users, so the process of using Tkey Messenger is very simple. If you want to install TKEY-ME on your laptop or computer, just download the installer from the official website and enjoy it.

IQ.Cash Cryptocurrency - Way To Generate is good service
https://preview.redd.it/09qg35tzgdx41.jpg?width=512&format=pjpg&auto=webp&s=b45ef29b97cea3d317e54c14ee61ea5968ad4830 The IQ.cash project team has already developed for their investors the IQ Masternode network that they use. Also, the IQ coin is presented on such well-known exchanges as HitBTC, BitHumb Glogal, P2PB2B, CoinsBit, BitForex, CREX24 and Mercatox. Therefore, traders can easily trade it! If an investor has more than 3000 IQ on his balance sheet, then he can receive passive income 57% of the block, miners, in turn, receive 43% of the block. We still have 6%, which are reserved for DAO (decentralized autonomous organizations), that is, they are used to invest, for example, in ICO projects, websites, trading bots, and improving the entire IQ ecosystem . cash and so on. All of these unique features can help make the IQ.cash platform popular around the world. You may come to this article to find out about the massive passive income, but worth noting that you should know what it is about. Think about it, investing money to something vague is very risky. Thus, what is IQ cash? To make it brief, this is another cryptocurrency that has quite clear and potential income. Just like bitcoin, this IQcash has a potential fluctuation which increases and give great passive income through the magnificent distribution splits. It is also easy to say that IQ cash is an investment master nodes Cryptocurrency which is open for everyone. In this matter, whether it is for investors, traders, or even miners. Yes, those who are familiar with the world of cryptocurrency are the target of this project. The main task is to provide instant anonymous online payment along with the investing system. The IQ cash platform ecosystem work as DAO (decentralized Autonomous Organization. https://preview.redd.it/wgl5icd1hdx41.jpg?width=640&format=pjpg&auto=webp&s=0f0e8a7b032633c2e526f8f01bb1efc2cb659323 One thing that makes this digital money gain quite a lot of participants in the available wallets. Not a real physical wallet, but one to store all your cryptocurrency. In this case, the wallet is available for Windows, Linux, and Mac. You can choose one that fits with the equipment you have. Along with that, you can install the masternode on your home pc or Linux VPS. Your masternode will just do the earning rewards, without all the other extra features. If you want to install, you can use PC running windows Mac or even Linux. However, on VPS you have to use Linux with Ubuntu 16.04 version. Other than that, there are some requirements you have to fulfill. The first one is having a 3000 IQ or more on balance. Even 3001 coin is acceptable. Then, use only one PC for dedicated IP-address and also a 24/7 network connectivity (network loos less than 30 – 60 mins) without any interrupted operating system. Security - it is the most considered aspect of investment, as we know that investing in cyberspace is very risky. Therefore, IQ.Cash presents the security of investor accounts, where all accounts cannot be blocked and, most importantly, account funds can only be accessed by the account holder. Masternodes - how do we know IQ. Cash uses the PoW consensus algorithm that supports the Masternode system. this certainly adds to the intrinsic value of this project, which economically can add a value of approximately 43% and indirectly increases passive income by around 57% for all participants in the masternode. Masternode provides network integrity. Transaction anonymity and transaction speed. Of course, to run a masternode system, everyone can only invest 3000 IQ and then immediately enjoy the results obtained with this IQ.Cash masternode feature. Anonymity of the transaction - this is more about the privacy of the transaction itself. where users can completely trust the system. and you don’t have to worry about data access by irresponsible parties. because the system automatically encrypts data when transferring and receiving assets https://preview.redd.it/7k0i4s47hdx41.png?width=640&format=png&auto=webp&s=cc9b5ced02917e1549e9b963805785df93b332d2 The IQ.cash platform operates on the basis of the POW consensus with support for a system such as MASTERNODE. And this is very cool, since this system makes the project more interesting and attractive for crypto enthusiasts. Indeed, thanks to the MASTERNODE system, miners receive 43% from mining, and people who own MASTERNODE receive a passive income of 57%. MASTERNODE supports the network, i.e. data privacy, transaction anonymity and speed, and much more. To become the owner of MASTERNODE you need to have more than 3000 IQ on your balance sheet. Anonymity. Transaction anonymity is provided by the PrivateSend algorithm. Users can feel safe and not worry about their assets. Since this system perfectly encrypts data. Therefore, you can safely send and receive any crypto assets. ASIC RESISTANCE. This technology is struggling with such a serious problem as a significant acceleration in the growth of network complexity. IQ network . cash works on the basis of the NeoScrypt algorithm, which is struggling with this problem. High transaction speed. Such an instant transaction speed, because the InstantSend algorithm works. Just think about it, the transaction speed is only about five seconds. Absolute decentralization. Affect both participants and crypto assets of the IQ network . cash no one can. Because everything will be safe, reliable and transparent. Only requires a transaction speed of only about 5 seconds / transaction. And all transactions are done instantly, so this will provide a very efficient way of working for the users later. more and more projects have started to appear, whose actions are directed to one of the niches of our daily activities. This is excellent, we have been waiting for this for many years, but at the moment, strange as it may seem, projects aimed exclusively at the crypto industry have become a minor order of magnitude. It was simply impossible to take it. And now a project has appeared on the horizon that positions its activities exclusively as a useful product for mining companies, investors and even traders. As it turned out, the team has a work product, whose currency is traded on many major exchanges. That's good luck, I smiled and started to study the IQ.cash project and its capabilities. Go back to the main interface and choose a personal tab (bottom right corner). Then, move to the next phase by choosing the Fee & Payment tab. You will see fee balance, FLS, BTC fee deposit address, and other information. In here, copy the IQ.cash wallet address in the FLS address tab. To move on to the next stages, you should have bought the required number of IQ cash (3000 IQ cash) beforehand. You can buy the IQ cash masternode from the official sites.

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything. The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years. In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.
UPDATED - Groestlcoin Core 2.18.2
This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables. NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.
Builds are now done through Gitian
Calls to getblocktemplate will fail if the segwit rule is not specified. Calling getblocktemplate without segwit specified is almost certainly a misconfiguration since doing so results in lower rewards for the miner. Failed calls will produce an error message describing how to enable the segwit rule.
A warning is printed if an unrecognized section name is used in the configuration file. Recognized sections are [test], [main], and [regtest].
Four new options are available for configuring the maximum number of messages that ZMQ will queue in memory (the "high water mark") before dropping additional messages. The default value is 1,000, the same as was used for previous releases.
The rpcallowip option can no longer be used to automatically listen on all network interfaces. Instead, the rpcbind parameter must be used to specify the IP addresses to listen on. Listening for RPC commands over a public network connection is insecure and should be disabled, so a warning is now printed if a user selects such a configuration. If you need to expose RPC in order to use a tool like Docker, ensure you only bind RPC to your localhost, e.g. docker run [...] -p 127.0.0.1:1441:1441 (this is an extra :1441 over the normal Docker port specification).
The rpcpassword option now causes a startup error if the password set in the configuration file contains a hash character (#), as it's ambiguous whether the hash character is meant for the password or as a comment.
The whitelistforcerelay option is used to relay transactions from whitelisted peers even when not accepted to the mempool. This option now defaults to being off, so that changes in policy and disconnect/ban behavior will not cause a node that is whitelisting another to be dropped by peers.
A new short about the JSON-RPC interface describes cases where the results of anRPC might contain inconsistencies between data sourced from differentsubsystems, such as wallet state and mempool state.
A new document introduces Groestlcoin Core's BIP174 interface, which is used to allow multiple programs to collaboratively work to create, sign, and broadcast new transactions. This is useful for offline (cold storage) wallets, multisig wallets, coinjoin implementations, and many other cases where two or more programs need to interact to generate a complete transaction.
The output script descriptor (https://github.com/groestlcoin/groestlcoin/blob/mastedoc/descriptors.md) documentation has been updated with information about new features in this still-developing language for describing the output scripts that a wallet or other program wants to receive notifications for, such as which addresses it wants to know received payments. The language is currently used in multiple new and updated RPCs described in these release notes and is expected to be adapted to other RPCs and to the underlying wallet structure.
A new --disable-bip70 option may be passed to ./configure to prevent Groestlcoin-Qt from being built with support for the BIP70 payment protocol or from linking libssl. As the payment protocol has exposed Groestlcoin Core to libssl vulnerabilities in the past, builders who don't need BIP70 support are encouraged to use this option to reduce their exposure to future vulnerabilities.
The minimum required version of Qt (when building the GUI) has been increased from 5.2 to 5.5.1 (the depends system provides 5.9.7)
getnodeaddresses returns peer addresses known to this node. It may be used to find nodes to connect to without using a DNS seeder.
listwalletdir returns a list of wallets in the wallet directory (either the default wallet directory or the directory configured bythe -walletdir parameter).
getrpcinfo returns runtime details of the RPC server. Currently, it returns an array of the currently active commands and how long they've been running.
deriveaddresses returns one or more addresses corresponding to an output descriptor.
getdescriptorinfo accepts a descriptor and returns information aboutit, including its computed checksum.
joinpsbts merges multiple distinct PSBTs into a single PSBT. The multiple PSBTs must have different inputs. The resulting PSBT will contain every input and output from all the PSBTs. Any signatures provided in any of the PSBTs will be dropped.
analyzepsbt examines a PSBT and provides information about what the PSBT contains and the next steps that need to be taken in order to complete the transaction. For each input of a PSBT, analyze psbt provides information about what information is missing for that input, including whether a UTXO needs to be provided, what pubkeys still need to be provided, which scripts need to be provided, and what signatures are still needed. Every input will also list which role is needed to complete that input, and analyzepsbt will also list the next role in general needed to complete the PSBT. analyzepsbt will also provide the estimated fee rate and estimated virtual size of the completed transaction if it has enough information to do so.
utxoupdatepsbt searches the set of Unspent Transaction Outputs (UTXOs) to find the outputs being spent by the partial transaction. PSBTs need to have the UTXOs being spent to be provided because the signing algorithm requires information from the UTXO being spent. For segwit inputs, only the UTXO itself is necessary. For non-segwit outputs, the entire previous transaction is needed so that signers can be sure that they are signing the correct thing. Unfortunately, because the UTXO set only contains UTXOs and not full transactions, utxoupdatepsbt will only add the UTXO for segwit inputs.
getpeerinfo now returns an additional minfeefilter field set to the peer's BIP133 fee filter. You can use this to detect that you have peers that are willing to accept transactions below the default minimum relay fee.
The mempool RPCs, such as getrawmempool with verbose=true, now return an additional "bip125-replaceable" value indicating whether thetransaction (or its unconfirmed ancestors) opts-in to asking nodes and miners to replace it with a higher-feerate transaction spending any of the same inputs.
settxfee previously silently ignored attempts to set the fee below the allowed minimums. It now prints a warning. The special value of"0" may still be used to request the minimum value.
getaddressinfo now provides an ischange field indicating whether the wallet used the address in a change output.
importmulti has been updated to support P2WSH, P2WPKH, P2SH-P2WPKH, and P2SH-P2WSH. Requests for P2WSH and P2SH-P2WSH accept an additional witnessscript parameter.
importmulti now returns an additional warnings field for each request with an array of strings explaining when fields are being ignored or are inconsistent, if there are any.
getaddressinfo now returns an additional solvable Boolean field when Groestlcoin Core knows enough about the address's scriptPubKey, optional redeemScript, and optional witnessScript for the wallet to be able to generate an unsigned input spending funds sent to that address.
The getaddressinfo, listunspent, and scantxoutset RPCs now return an additional desc field that contains an output descriptor containing all key paths and signing information for the address (except for the private key). The desc field is only returned for getaddressinfo and listunspent when the address is solvable.
importprivkey will preserve previously-set labels for addresses or public keys corresponding to the private key being imported. For example, if you imported a watch-only address with the label "coldwallet" in earlier releases of Groestlcoin Core, subsequently importing the private key would default to resetting the address's label to the default empty-string label (""). In this release, the previous label of "cold wallet" will be retained. If you optionally specify any label besides the default when calling importprivkey, the new label will be applied to the address.
getmininginfo now omits currentblockweight and currentblocktx when a block was never assembled via RPC on this node.
The getrawtransaction RPC & REST endpoints no longer check the unspent UTXO set for a transaction. The remaining behaviors are as follows:
If a blockhash is provided, check the corresponding block.
If no blockhash is provided, check the mempool.
If no blockhash is provided but txindex is enabled, also check txindex.
unloadwallet is now synchronous, meaning it will not return until the wallet is fully unloaded.
importmulti now supports importing of addresses from descriptors. A desc parameter can be provided instead of the "scriptPubKey" in are quest, as well as an optional range for ranged descriptors to specify the start and end of the range to import. Descriptors with key origin information imported through importmulti will have their key origin information stored in the wallet for use with creating PSBTs.
listunspent has been modified so that it also returns witnessScript, the witness script in the case of a P2WSH orP2SH-P2WSH output.
createwallet now has an optional blank argument that can be used to create a blank wallet. Blank wallets do not have any keys or HDseed. They cannot be opened in software older than 2.18.2. Once a blank wallet has a HD seed set (by using sethdseed) or private keys, scripts, addresses, and other watch only things have been imported, the wallet is no longer blank and can be opened in 2.17.2. Encrypting a blank wallet will also set a HD seed for it.
signrawtransaction is removed after being deprecated and hidden behind a special configuration option in version 2.17.2.
The 'account' API is removed after being deprecated in v2.17.2 The 'label' API was introduced in v2.17.2 as a replacement for accounts. See the release notes from v2.17.2 for a full description of the changes from the 'account' API to the 'label' API.
addwitnessaddress is removed after being deprecated in version 2.16.0.
generate is deprecated and will be fully removed in a subsequent major version. This RPC is only used for testing, but its implementation reached across multiple subsystems (wallet and mining), so it is being deprecated to simplify the wallet-node interface. Projects that are using generate for testing purposes should transition to using the generatetoaddress RPC, which does not require or use the wallet component. Calling generatetoaddress with an address returned by the getnewaddress RPC gives the same functionality as the old generate RPC. To continue using generate in this version, restart groestlcoind with the -deprecatedrpc=generate configuration option.
Be reminded that parts of the validateaddress command have been deprecated and moved to getaddressinfo. The following deprecated fields have moved to getaddressinfo: ismine, iswatchonly,script, hex, pubkeys, sigsrequired, pubkey, embedded,iscompressed, label, timestamp, hdkeypath, hdmasterkeyid.
The addresses field has been removed from the validateaddressand getaddressinfo RPC methods. This field was confusing since it referred to public keys using their P2PKH address. Clients should use the embedded.address field for P2SH or P2WSH wrapped addresses, and pubkeys for inspecting multisig participants.
A new /rest/blockhashbyheight/ endpoint is added for fetching the hash of the block in the current best blockchain based on its height (how many blocks it is after the Genesis Block).
A new Window menu is added alongside the existing File, Settings, and Help menus. Several items from the other menus that opened new windows have been moved to this new Window menu.
In the Send tab, the checkbox for "pay only the required fee" has been removed. Instead, the user can simply decrease the value in the Custom Fee rate field all the way down to the node's configured minimumrelay fee.
In the Overview tab, the watch-only balance will be the only balance shown if the wallet was created using the createwallet RPC and thedisable_private_keys parameter was set to true.
The launch-on-startup option is no longer available on macOS if compiled with macosx min version greater than 10.11 (useCXXFLAGS="-mmacosx-version-min=10.11" CFLAGS="-mmacosx-version-min=10.11" for setting the deployment sdkversion)
A new groestlcoin-wallet tool is now distributed alongside Groestlcoin Core's other executables. Without needing to use any RPCs, this tool can currently create a new wallet file or display some basic information about an existing wallet, such as whether the wallet is encrypted, whether it uses an HD seed, how many transactions it contains, and how many address book entries it has.
Since version 2.16.0, Groestlcoin Core's built-in wallet has defaulted to generating P2SH-wrapped segwit addresses when users want to receive payments. These addresses are backwards compatible with all widely used software. Starting with Groestlcoin Core 2.20.1 (expected about a year after 2.18.2), Groestlcoin Core will default to native segwitaddresses (bech32) that provide additional fee savings and other benefits. Currently, many wallets and services already support sending to bech32 addresses, and if the Groestlcoin Core project sees enough additional adoption, it will instead default to bech32 receiving addresses in Groestlcoin Core 2.19.1. P2SH-wrapped segwit addresses will continue to be provided if the user requests them in the GUI or by RPC, and anyone who doesn't want the update will be able to configure their default address type. (Similarly, pioneering users who want to change their default now may set the addresstype=bech32 configuration option in any Groestlcoin Core release from 2.16.0 up.)
BIP 61 reject messages are now deprecated. Reject messages have no use case on the P2P network and are only logged for debugging by most network nodes. Furthermore, they increase bandwidth and can be harmful for privacy and security. It has been possible to disable BIP 61 messages since v2.17.2 with the -enablebip61=0 option. BIP 61 messages will be disabled by default in a future version, before being removed entirely.
The submitblock RPC previously returned the reason a rejected block was invalid the first time it processed that block but returned a generic "duplicate" rejection message on subsequent occasions it processed the same block. It now always returns the fundamental reason for rejecting an invalid block and only returns "duplicate" for valid blocks it has already accepted.
A new submitheader RPC allows submitting block headers independently from their block. This is likely only useful for testing.
The signrawtransactionwithkey and signrawtransactionwithwallet RPCs have been modified so that they also optionally accept a witnessScript, the witness script in the case of a P2WSH orP2SH-P2WSH output. This is compatible with the change to listunspent.
For the walletprocesspsbt and walletcreatefundedpsbt RPCs, if thebip32derivs parameter is set to true but the key metadata for a public key has not been updated yet, then that key will have a derivation path as if it were just an independent key (i.e. no derivation path and its master fingerprint is itself).
The -usehd configuration option was removed in version 2.16.0 From that version onwards, all new wallets created are hierarchical deterministic wallets. This release makes specifying -usehd an invalid configuration option.
This release allows peers that your node automatically disconnected for misbehaviour (e.g. sending invalid data) to reconnect to your node if you have unused incoming connection slots. If your slots fill up, a misbehaving node will be disconnected to make room for nodes without a history of problems (unless the misbehaving node helps your node in some other way, such as by connecting to a part of the Internet from which you don't have many other peers). Previously, Groestlcoin Core banned the IP addresses of misbehaving peers for a period (default of 1 day); this was easily circumvented by attackers with multiple IP addresses. If you manually ban a peer, such as by using the setban RPC, all connections from that peer will still be rejected.
The key metadata will need to be upgraded the first time that the HDseed is available. For unencrypted wallets this will occur on wallet loading. For encrypted wallets this will occur the first time the wallet is unlocked.
Newly encrypted wallets will no longer require restarting the software. Instead such wallets will be completely unloaded and reloaded to achieve the same effect.
A sub-project of Bitcoin Core now provides Hardware Wallet Interaction (HWI) scripts that allow command-line users to use several popular hardware key management devices with Groestlcoin Core. See their project page for details.
This release changes the Random Number Generator (RNG) used from OpenSSL to Groestlcoin Core's own implementation, although entropy gathered by Groestlcoin Core is fed out to OpenSSL and then read back in when the program needs strong randomness. This moves Groestlcoin Core a little closer to no longer needing to depend on OpenSSL, a dependency that has caused security issues in the past. The new implementation gathers entropy from multiple sources, including from hardware supporting the rdseed CPU instruction.
On macOS, Groestlcoin Core now opts out of application CPU throttling ("app nap") during initial blockchain download, when catching up from over 100 blocks behind the current chain tip, or when reindexing chain data. This helps prevent these operations from taking an excessively long time because the operating system is attempting to conserve power.
How to Upgrade?
Windows If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer. OSX If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), run the dmg and drag Groestlcoin Core to Applications.

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet
Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network. GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.
Groestlcoin Mainnet & Testnet supported
Multiple wallet support
Electrum - Support for both random and custom peers
Biometric + Pin authentication
Custom fee selection
Import mnemonic phrases via manual entry or scanning
BIP39 Passphrase functionality
Support for Segwit-compatible & legacy addresses in settings
Support individual private key sweeping
UTXO blacklisting - Accessible via the Transaction Detail view, this allows users to blacklist any utxo that they do not wish to include in their list of available utxo's when sending transactions. Blacklisting a utxo excludes its amount from the wallet's total balance.
Ability to Sign & Verify Messages
Support BitID for password-free authentication
Coin Control - This can be accessed from the Send Transaction view and basically allows users to select from a list of available UTXO's to include in their transaction.
HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled. HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user. Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.
Simplified payment verification for fast mobile performance
Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases. This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats. To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.
If a word is wrong, the tool will try to suggest the closest option.
If a word is missing or unknown, please type "?" instead and the tool will find all relevant options.
NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator. VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline. If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address. VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase. VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).
Fixed size arithmetic
Fast Modular Inversion (Delayed Right Shift 62 bits)
SecpK1 Fast modular multiplication (2 steps folding 512bits to 256bits using 64 bits digits)
Use some properties of elliptic curve to generate more keys
SSE Secure Hash Algorithm SHA256 and RIPEMD160 (CPU)
Groestlcoin EasyVanity 2020 is a windows app built from the ground-up and makes it easier than ever before to create your very own bespoke bech32 address(es) when whilst not connected to the internet. If you're tired of the random, cryptic bech32 addresses generated by regular Groestlcoin clients, then Groestlcoin EasyVanity2020 is the right choice for you to create a more personalised bech32 address. This 2020 version uses the new VanitySearch to generate not only legacy addresses (F prefix) but also Bech32 addresses (grs1 prefix).
Ability to continue finding keys after first one is found
Includes warning on start-up if connected to the internet
Ability to output keys to a text file (And shows button to open that directory)
Show and hide the private key with a simple toggle switch
Show full output of commands
Ability to choose between Processor (CPU) and Graphics Card (GPU) ( NVidia ONLY! )
Features both a Light and Dark Material Design-Style Themes
Free software - MIT. Anyone can audit the code.
Written in C# - The code is short, and easy to review.
Groestlcoin WPF is an alternative full node client with optional lightweight 'thin-client' mode based on WPF. Windows Presentation Foundation (WPF) is one of Microsoft's latest approaches to a GUI framework, used with the .NET framework. Its main advantages over the original Groestlcoin client include support for exporting blockchain.dat and including a lite wallet mode. This wallet was previously deprecated but has been brought back to life with modern standards.
Works via TOR or SOCKS5 proxy
Can use bootstrap.dat format as blockchain database
Import/Export blockchain to/from bootstrap.dat
Import wallet.dat from Groestlcoin-qt wallet
Export wallet to wallet.dat
Use both groestlcoin-wpf and groestlcoin-qt with the same addresses in parallel. When you send money from one program, the transaction will automatically be visible on the other wallet.
Rescan blockchain with a simple mouse click
Works as a full node and listens to port 1331 (listening port can be changed)
Fast Block verifying, parallel processing on multi-core CPUs
Mine Groestlcoins with your CPU by a simple mouse click
All private keys are kept encrypted on your local machine (or on a USB stick)
Lite - Has a lightweight "thin client" mode which does not require a new user to download the entire Groestlcoin chain and store it
Free and decentralised - Open Source under GNU license
Fixed Import/Export to wallet.dat
Rescan wallet option
Change wallet password option
Address type and Change type options through *.conf file
Import from bootstrap.dat - It is a flat, binary file containing Groestlcoin blockchain data, from the genesis block through a recent height. All versions automatically validate and import the file "grs.bootstrap.dat" in the GRS directory. Grs.bootstrap.dat is compatible with Qt wallet. GroestlCoin-Qt can load from it.
In Full mode file %APPDATA%\Groestlcoin-WPF\GRS\GRS.bootstrap.dat is full blockchain in standard bootstrap.dat format and can be used with other clients.
Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node. It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node. Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine. Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in. Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet. Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.
Use your own node
Uses less CPU and RAM than ElectrumX
Used intermittently rather than needing to be always-on
Doesn't require an index of every Groestlcoin address ever used like on ElectrumX
UPDATED – Android Wallet 7.38.1 - Main Net + Test Net
The app allows you to send and receive Groestlcoin on your device using QR codes and URI links. When using this app, please back up your wallet and email them to yourself! This will save your wallet in a password protected file. Then your coins can be retrieved even if you lose your phone.
Add confidence messages, helping users to understand the confidence state of their payments.
Handle edge case when restoring via an external app.
Count devices with a memory class of 128 MB as low ram.
Introduce dark mode on Android 10 devices.
Reduce memory usage of PIN-protected wallets.
Tapping on the app's version will reveal a checksum of the APK that was installed.
Fix issue with confirmation of transactions that empty your wallet.
Groestlcoin Sentinel is a great solution for anyone who wants the convenience and utility of a hot wallet for receiving payments directly into their cold storage (or hardware wallets). Sentinel accepts XPUB's, YPUB'S, ZPUB's and individual Groestlcoin address. Once added you will be able to view balances, view transactions, and (in the case of XPUB's, YPUB's and ZPUB's) deterministically generate addresses for that wallet. Groestlcoin Sentinel is a fork of Groestlcoin Samourai Wallet with all spending and transaction building code removed.

Hello, I have been a fan of electrum because of its offline capability. I like that I can use Bitcoin while storing my private keys on a computer that has the wifi card removed and hot glue stuffed in the Ethernet port. However it looks like maybe the electrum developers have over-promised and under-delivered in this regard. Or, maybe they simply do not have the time, energy, resources to make this work in real life. Let me explain. I have an old-ass computer that is running Ubuntu 12 (precise), this computer has electrum 2.5.4 installed with a cold-storage wallet that has my private key. I want to send some bitcoin from that address to a new wallet on my desktop so I can spend the bitcoin. So I installed electrum (newest version 3.3.8) on my desktop, imported the bitcoin address, and created a transaction. Then I sent the transaction to the offline computer out of band, and verified that the out-of-band transmission worked by comparing the hash of the txn file on both the offline and online machines. Then I tried to open the txn file on the offline machine with Electrum 2.5.4. Well, guess what, it didn't work. Electrum 2.5.4 printed to the console: Traceback (most recent call last): File "/uslocal/lib/python2.7/dist-packages/Electrum-2.5.4-py2.7.egg/electrum_gui/qt/main_window.py", line 2261, in do_process_from_file self.show_transaction(tx) File "/uslocal/lib/python2.7/dist-packages/Electrum-2.5.4-py2.7.egg/electrum_gui/qt/main_window.py", line 577, in show_transaction show_transaction(tx, self, tx_desc) File "/uslocal/lib/python2.7/dist-packages/Electrum-2.5.4-py2.7.egg/electrum_gui/qt/transaction_dialog.py", line 37, in show_transaction d = TxDialog(tx, parent, desc, prompt_if_unsaved) File "/uslocal/lib/python2.7/dist-packages/Electrum-2.5.4-py2.7.egg/electrum_gui/qt/transaction_dialog.py", line 48, in __init__ self.tx.deserialize() File "/uslocal/lib/python2.7/dist-packages/Electrum-2.5.4-py2.7.egg/electrum/transaction.py", line 523, in deserialize d = deserialize(self.raw) File "/uslocal/lib/python2.7/dist-packages/Electrum-2.5.4-py2.7.egg/electrum/transaction.py", line 454, in deserialize d[inputs] = list(parse_input(vds) for i in xrange(n_vin)) OverflowError: Python int too large to convert to C long That's pretty frustrating, the first thing I tried was to install Electrum 2.5.4 on my Desktop and try to create a new unsigned transaction with Electrum 2.5.4. However, this is a no-go because old versions of Electrum cannot connect to Electrum servers any more. So I have to try to update the Electrum on the Offline computer. But I'm not even sure if this is possible considering how ubuntu 12 it's definitely out of support at this point and the offline computer does not even have python3 installed, let alone the GTK stuff or whatever is probably required to run Electrum. I'm starting to regret choosing a GUI-based wallet for my offline storage considering how hard it is to actually use this and how it simply melts over time... even just 5 years is is enough time to completely melt and destroy this software and make it un-usable. Time Catches All. So now I have to go out and buy a new computer that can run the updated OS, so I can install the new version of Electrum, so I can access my bitcoin. Do you have any other ideas? Has anyone else experienced anything like this?
I have a little home server running Ubuntu 18.04 LTS. Full Bitcoin node + Electrum Personal Server + Electrum, all running fine. I recently added LND Lightning node, opened and funded a few channels, all fun to do. All this is going over Tor. As long as I'm running wallets on my Ubuntu server, I have no problem to connect to the nodes (on the same machine). What I can't seem to figure out, is how to connect my wallets from other devices:
how can I connect Electrum from my laptop to my Bitcoin node via EPS?
how can I connect BlueWallet or Zap from my phone to the Lightning node?
first I want to achieve this over my local network, but this should be possible over internet as well?
There's plenty of guides to set up nodes, but I couldn't find anything that helped me with this. Anyone can point me in the right direction? Thanks. EDIT 01: I tried setting up LndHub to connect BlueWallet, but I got lost in the installation guide EDIT 02: when using lndconnect or Web lndconnect for Zap, I get the following message: "Could not connect to server. (Connect Failed)". Turning off the Ubuntu firewall makes no difference
first time docker user. i need some help with setting up docker on wsl.
i followed u/nickjj_'s guide "Setting Up Docker for Windows and WSL to Work Flawlessly" up to the "Configure WSL to Connect to Docker for Windows" section where i learned that i also need to install docker on windows. yes, the article was clear and mentioned this at the beginning, but being the i am, i thought i could skip this and install docker as i did in a live ubuntu. so i went to docker hub, created an id and downloaded "docker desktop for windows" how should i now set up docker desktop for windows (126.96.36.199) to make it work with wsl? i have windows 10 home and installation failed because it seems it needs win 10 pro or enterprise version 15063 to run. any work arounds to make this work? i am trying to build an appimage for the electrum bitcoin wallet and one of the main developers suggested that i might be able to use docker on wsl.
Storage space: I am using an 8 GB microSD card for the OS, and a 128 GB USB drive for data. Minimums I would recommend: 8GB SD card and 32 GB USB drive.
Reddcoin Core client version: v188.8.131.52-a8767ba-beta (most recent version at this moment). ↳ Screenshot
You need the OS; Lubuntu. Download Lubuntu (707 MB) for the Raspberry Pi: https://ubuntu-pi-flavour-maker.org/download/. It's a .torrent download, so you will need a BitTorrent client. Message me or post in this thread if you need help with this.
You need software to write the OS to the SD card. I use Etcher. Download Etcher: https://etcher.io/.
Select image: select the lubuntu-16.04.2-desktop-armhf-raspberry-pi.img.xz file.
Select drive: select your microSD card.
Plug the SD card into your Raspberry Pi and power it up.
Lubuntu should boot up.
Set up Lubuntu, connect to the internet (wired or wireless). ↳ As username, I chose "rpi3b". You will see this username throughout this whole tutorial.
Make sure date and time are correct ([Menu] > System Tools > Time and Date). ↳ Click on Unlock to make changes. I personally change Configuration to "Keep synchronized with Internet servers". ↳ Screenshot
Reboot ([Menu] > Logout > Reboot). I am connected to wifi, but have issues getting wifi to work on initial boot. A reboot solves this issue.
Make sure system is up-to-date, install never versions.
Open LXTerminal ([Menu] > System Tools > LXTerminal). ↳ Screenshot
Enter the following in LXTerminal: sudo apt update && sudo apt upgrade ↳ Screenshot
You will be asked if you really want to continue. Enter Y (yes).
Updates are being installed! Wait until it's finished.
Install programs that will be used in this tutorial.
GParted: to partition the USB drive.
Htop: to see the amount of memory (RAM) and swap that is in use.
Enter the following in LXTerminal to install these 2 programs. sudo apt install gparted && sudo apt install htop ↳ Screenshot
Create 2 partitions on the USB drive: 1) Swap partition 2) data partition (for the Reddcoin blockchain) The swap partition is necessary: The Reddcoin wallet can be memory intensive. To prevent any crashes or freezes, add 2 GB of 'virtual' memory by creating a swap partition.
Important: Backup your USB drive if needed. The USB drive will be formatted, so the data on the USB drive will be wiped.
Please use the USB drive solely for this purpose, do not combine it with other stuff.
Keep your USB drive plugged in, do not (randomly) plug it out.
Plug your USB drive in.
GParted will be used to create the partititons. Start GParted via LXTerminal: sudo gparted ↳ Screenshot
Apply the changes. Click on the check mark or select Edit > Apply All Operations. ↳ Screenshot ↳ Screenshot
Important: The name of the swap partition is needed later, so please write it down. Mine is /dev/sda1 (first partition on first drive (drive 'a')). ↳ Screenshot
Reboot. After the reboot, the data partition you just created should be visible on your desktop. ↳ Screenshot
The swap partition is created, so now we can enable and use it.
The swap in use can be monitored with the program Htop. Open Htop ([Menu] > System Tools > Htop) to see the 'Swp' (swap) in use. ↳ Screenshot By default, swap is not used, so 0K. ↳ Screenshot You can leave Htop open.
To enable the swap partition, open LXTerminal and enter the following commands: (Assuming /dev/sda1 is your swap partition.)
Unpack the file (large file, takes around 15 minutes to unpack): sudo xz -d bootstrap.dat.xz ↳ Screenshot
After a successful unpack, your will find the file bootstrap.dat in your USB root folder. ↳ Screenshot
On the first run of the Reddcoin Core client, it will ask for a data directory to store the blockchain and wallet data.
Start the Reddcoin Core client: sudo /media/rpi3b/usb/reddcoin/src/qt/reddcoin-qt ↳ Screenshot
The welcome screen will appear and ask you about the data directory. I suggest a new folder on your USB drive, I picked blockchain. The directory will be created with all the necessary files. ↳ Screenshot
Click on the three dots (...) on the right. ↳ Screenshot
Click on Create Folder at the upper right corner. Type and enter in the folder name. (In my case: blockchain.) Click on Open. ↳ Screenshot ↳ Screenshot ↳ Screenshot
After selecting the directory, the Reddcoin Core client will start. Wait till it's fully loaded and close it.
Move the bootstrap.dat file to your data directory you selected in the previous step. By doing this, Reddcoin Core will use the bootstrap.dat file to import the blockchain, which speeds up syncing. sudo mv bootstrap.dat /media/rpi3b/usb/blockchain/ (Assuming blockchain as data directory.) ↳ Screenshot
The Reddcoin Core client set up is completed, but you still have to sync fully with the blockchain before you can send, receive and stake.
Keep the client running until it's fully synchronized. It will use the bootstrap file first, and download the rest of the blockchain to complete the sync. This can take some time (it took 2 days for me). Syncing the blockchain uses a lot of resources, so the software may react slow.
You can see the progress in the debug window (Help > Debug window). ↳ Screenshot
When the synchronization is completed, the red (out of sync) will disappear on the Overview screen! ↳ Screenshot
When synchronization is complete, you can start staking your Reddcoins.
You can write down your private key or copy and save it in a document. Make sure you save it somewhere only you can access it.
To import later: Debug window -> Console -> importprivkey [label] [label] is optional. ↳ Screenshot (without a label) ↳ Screenshot (with a label)
Boot with only 1 USB drive plugged in: Make sure only the USB drive (with the swap partition and data partition) is plugged in when you boot up your Raspberry Pi. This to make sure the swap partition (/dev/sda1) is recognized correctly. If you boot up with multiple USB drives, Lubuntu might see the USB drive with the swap partition as the second drive (instead of the first drive), and ignore the 2 GB swap partition. If this happens, starting Reddcoin can render the Raspberry Pi unresponsive.
Start Reddcoin Core easier Run a shell script (.sh file), so you can start Reddcoin just by double clicking on an icon on your Desktop.
Right Click on your Desktop and select Create New -> Empty File. ↳ Screenshot
Enter a file name, make sure it ends with .sh, and click on OK. I've chosen for Reddcoin.sh. ↳ Screenshot The file will be created on your Desktop. ↳ Screenshot
Add the command to start Reddcoin to the file.
Right click on the file, select Leafpad (to open the file in a text editor). ↳ Screenshot
Add the following to the file and save the file: sudo /media/rpi3b/usb/reddcoin/src/qt/reddcoin-qt ↳ Screenshot
To be able to execute the shell script (.sh), it has to have 'execute permissions'.
Right click on the file, and select Properties. ↳ Screenshot
Click on the Permissions tab.
For Execute, select Anyone, and click on OK. ↳ Screenshot
To start Reddcoin Core, double click on the file. A new window will pop-up, asking you what you want. Execute in Terminal is what we want, so you can click on enter. ↳ Screenshot Reddcoin Core will now start. Do not close the Terminal window, you can minimize it if needed.
Minimization options Adjust minimization options, so you can safely press on the X button (the close/exit button on the upper right corner).
Activate 'Minimize on close'. Settings -> Options... -> Window (tab) -> Minimize on close. ↳ Screenshot Reddcoin will still run when you click on the X button. To close/exit Reddcoin, right click on the Reddcoin icon in the system tray (bottom right corner). ↳ Screenshot
RealVNC VNC Viewer (client) and VNC Connect (server): To remote connect to the Raspberry Pi, I use VNC Viewer ad VNC Connect from RealVNC.
After your download is finished, open the file and click Install Package. ↳ Screenshot
To run the VNC Connect once:
Open [Menu] > Run, and enter: vncserver-x11 ↳ Screenshot

We need to figure out how to help newbies store and use their bitcoin safely
This is how I do it: BACKUP: master private seed words on paper , saved securely. REGULAR USE: Preparation: Created a USB bootable linux , install electrum on it , disabled its internet/networking (IMPORTANT!), put private keys in electrum wallet, copy public keys from electrum wallet to usb drive. Boot to regular OS (windows/mac) , open electrum, create watching only wallet with public keys saved on USB. Using: Create transaction in electrum on regular OS -> save transaction to file on USB . Boot into usb linux -> load transaction from USB in electrum -> sign it, save to USB -> boot to regular OS -> load singed transaction from USB in electrum -> Broadcast! Add encryption and passwords to the above, and I think its a fairly bullet proof method of storing bitcoins. The private keys are never exposed to any network. I struggled at the part of disabling internet, but it worked out in the end. Obviously, this process is hard for the average joe. He will just keep his coins on some web wallet, defeating the point of bitcoin, and set themselves up to lose their btc down the road. There really need to be a method to make this easier. Maybe a modified version of ubuntu, with no networking, encryption and electrum preinstalled ? There is trezor , but I don't have knowledge there. Comments?
I'm too late to be an early adopter of BTC, I screwed around in my CompSci classes a decade before the Genesis block instead of helping. I'm too late to mine BTC on my CPU, by almost a decade. I'm too late to mine BTC on my GPU, by several years. I'm almost too late to mine BTC on my ASICs, they'll be out of date in a few years. Maybe less. I've made TWO purchases with BTC, both to buy another ASIC. I'm sold some BTC. Ok, I'm too early there, but regret it just the same. I just spun up a testnet BTC node and installed the Eclair Lightning Network client. I did it on an OS I'm really not familiar with, Ubuntu is just different enough from Win10 to make me struggle. I could have done it on Win10, I chose the harder route. I'm NOT too late to do my little part to make this happen. I opened a channel between a testnet Core wallet and an online testnet wallet and bounced Lightning transactions back and forth for an hour, taking only a few seconds between transactions. Paid only 2 miner's fees. I could have sent transactions to anyone running a connected Lightning client just as fast. And vice versa. It took half an hour to fund the channel, yes. And another half an hour or so to secure my funds when I closed the channel. Had I done those transactions without Lightning, it'd have taken most of a day. Not even Bitcoin Cash's large block size could have done that, its limited by the same 10 minute heartbeat Bitcoin has. THIS feels like the future. I am NOT too late. Noone is. Edit: Holy moly my inbox. Thank you for the Gold, now I have something more to research. :) I did NOT expect this post to get that many hits overnight! It took me a while to read thru the comments, every one of them to this point, and I'm glad to see so much agreement, discussion, arguments, and even veiled insults to my username. Its all good, I get far worse on a good day IRL. A few more people know about LN, some good explanations were given, that is the kind of thing we're going to need to bootstrap the LN network. The complexity is a problem compared to standard bitcoin transactions and wallets...but you realize just how complex those wallets and transactions are? Maybe not, well-designed software hides all the gorey details. I imagine LN wallets will be the same given more development, all the channel business hidden to anyone using Easy-mode and the refunding of channels handled behind the scenes. Probably not the best place to put something like this, in an edit, but oh well. Again, thank you everyone, I'm gonna go do something not-BTC related for a few hours now, have fun!
Atomic Wallet - The Best Universal Litecoin Wallet!
Atomic Wallet - The Best Universal Litecoin Wallet! Hello, valuable crypto money followers. In this article, I would like to talk to you about the Atomic Wallet project. Just as we all know that the cryptocurrency industry have gotten to a level where it can’t be stopped any-longer, we should also remember that this technology is still being faced with the challenge of fiat to crypto exchange because several individuals that are interested in purchasing and investing in cryptocurrencies do not have a good platform to easily convert their local currencies to bitcoin or other crypto assets. Atomic wallet team have recognised this cogent issue and as such, they have come up with the great solution of integrating Simplex which is the largest licensed card processing company in the European Union. Atomic wallet as we all know is a multi-feature wallet which affords its users the ability to store and manage 300+ cryptocurrencies, exchange their cryptocurrencies assets easily into other cryptocurrencies, monitor the current price of the supported cryptocurrencies among other features. What Does the Project Promise? Indeed the task is focused; to deal with our crypto cash resources dependably and to work through a progressively secure framework. So how is this going to be? A standout amongst the most critical issues that separates the Atomic Wallet venture from different activities is; rather than crypto trades on this stage, rather than keeping all crypto keys on the stock trades, they keep this data on clients’ gadgets. The clarification is that; We are never again ready to take our private keys and we are exceptionally protected. This is a great improvement …
What are the exceptional features of this wallet
· Ability to control your private keys by yourself only · Private and anonymous transactions which prevents you from being hacked · Easy to use built in cryptocurrency exchange · Excellent user interface · Always active customer support · Reliable security measures which ensures the safety of users’ funds · Very cheap and affordable transaction fees
What is Litecoin wallet?
You need to use a program to manage your Litecoins, it will keep your private keys and provide additional functions such as sending, receiving, exchanging, and more. With these programs, you’re able to manage and control your funds.
Signs of a good Litecoin Wallet
1. Security. Wallet security means the way your Litecoins and other cryptos are protected from frauds and hacking, how you manage private keys and what security technologies a particular wallet supports. 2. Accessibility. This feature implies simplicity in use and the ability to withdraw your funds from the wallet. A friendly user interface is a vital point for new users. When choosing a litecoin wallet, pay attention to its interface and the amounts you are able to operate with. 3. Functionality. If you want to choose a good LTC wallet, check it for additional services support, such as an ability to exchange cryptocurrency or buy crypto with a bank-card/paypal, etc.) In some wallets, like Atomic or Exodus, it’s possible to exchange Litecoin right in the application without visiting third party websites. Cryptocurrency will be transferred directly on your address after the exchange. How does the framework work? A standout amongst the most loved pieces of the stage is; individuals can make their very own requests for the trade between digital currencies, and they can be incorporated into the change orders made by others, this is extremely extraordinary … To clarify this with a precedent; Let’s say I have a tad of Litecoin. I would prefer not to transform this Litecoini into dollars or Btc. So I need to get Lost with Ltc straightforwardly. You can change over Ltc to Iost by means of Exchange over the stage. You can even enter the sum physically in the event that you need. Right now you endorse the Exchange procedure, the Atomic Wallet begins the procedure to compute the most fitting commission and exchange the token at the greatest rate with the base expense. In this manner, as in the Ethereum framework, the cost of Gas isn’t given to the reasons, for example, the low token isn’t sent tokenize. The Atomic Wallet application has been deliberately arranged to be utilized on each stage to contact all crowds. These stages; MacOS, Windows, Ubuntu, Debian and Fedora. 4. Customer Support. This is a vitally important to receive a fast reply on users concerns and help with troubleshooting. Good customer care is a sign of a good product. How fast will the support team help you, if you have any troubles? Crypto market is too volatile to wait days/weeks till someone will the issue. It is a good practice to reply within 24 hours. How to setup Litecoin Wallet Manage your Litecoin wisely! Learn how to setup Atomic Wallet to send, receive, exchange and buy LTC. Buy Litecoin in a secure way Install Atomic Wallet Download the app. Atomic is a free and secure place to manage Bitcoin, Ethereum, XRP and more than 300+ assets. Verify your Identity Verification is required to prevent identity theft or fraud. Photo ID is required to make sure it's really you. Get Litecoin Start with $50 and up to $20,000 daily. Receive crypto on your wallet. Credit/Debit cards accepted. Get Wallet Buy Litecoin with Credit Card There are many ways to buy Litecoin (exchanges, hot wallets), but one of the most secure way to buy LTC is to use Atomic Wallet. With Atomic, you can easily purchase LTC, BTC, ETH, XRP, BCH and hold 300+ coins and tokens in one place where only you control your funds. Hold them and manage with comfortable interface. You can buy Litecoin with VISA/MasterCard right in the interface of Atomic Walletand convert your USD or EUR to LTC. Even if you have a JPY, CAD or any other currency card, those currencies are automatically converted to either EUR or USD, depending on your choice. It’s quite easy to use and doesn’t require specific tech skills.
Rates and Security
The fees are fixed at 7%. Each operation is fully conducted by Simplex, an EU licensed card processing company. You choose an amount and currency to buy and verify your ID. Then your bank holds funds until Simplex approves the request and makes an exchange. As a rule, you receive crypto in 24 hours. As a result, the creation of an appropriate application will undoubtedly increase the use of the Atom Wallet for some customers. According to the designers, more than 100,000 people have downloaded the Atom Wallet since the effort was disbanded. Most people use the wallet routinely. This is an approved sign of trust in the wallet! I'm sure that the full delivery of compact apps on Android and iOS will be another upgrade to attract new customers. This review is the author's personal opinion, based on information from public sources and is certainly not a trade or investment advice.
Thank you for running your own full Vertcoin node and supporting VTC network! We currently have 518 Full Nodes running.
Thank you for running your own full Vertcoin node and supporting VTC network! We currently have 518 Full Nodes running. Official node scanner list: https://scanner.vertcoin.org/nodes Since every full VTC node can only serve so many clients, it's important to do your part for the Vertcoin network and run your own full node. Q: WHAT IS A FULL NODE? A: Full nodes maintain a copy of the blockchain/ledger, distribute it to those downloading it, confirm transactions, and further spread out all of the previous functions to make the network more resilient. https://bitcoin.org/en/full-node Q: Do I need to be a miner? A: No, you don't need to be a miner. Miners create new blocks. Full nodes simply share existing blocks (the entire VTC blockchain) with the rest of VTC wallet users. Q: How do I run a Full VTC node on Intel NUC? A: Intel NUC Vertcoin full node installation done using Windows guide: https://github.com/vertcoin-project/VertDocs/blob/mastedocs/FullNodes/intel-nuc.md Q: How do I run a Full VTC node? A: It's actually quite easy to do. If you run Vertcoin-QT (Vertcoin Core Wallet) on your PC/MAC desktop, keep it active in the systray. Then, make sure that you map the public port 5889 of your router to the port 5889 on the machine running Vertcoin-QT or vertcoind. For people running a public p2pool node this should be a no-brainer: you already have a synchronized vertcoind. So if you haven't opened port 5889 do it now - it's all you have to do. Your node is then public and can serve blocks and relay transactions.This makes our network much stronger and will help it to perform better. Any old or low power computer is good enough to run a full VTC node. If you have a Raspberry Pi or any old PC lying around, install vertcoind and run it in the background. Q: How do I know if my Full Node is working correctly? A: To be a full node, you have to check to make sure you are accepting incoming connections. To do that, go under Help -> Debug Window. In the first tab, "Information", there is a Network "Number of Connections" which will show both incoming and outgoing connections. If the "In" is 0, then you are not a full node. If the "In" is greater than 0, you are acting as a full node and supporting VTC blockchain! Thank you!

Vertnode - An automated solution for installing Vertcoin node(s) on Single Board Computers
Hello Vertcoin Community, Eager to contribute to the Vertcoin Community I began creating step by step walkthrough guides on how to get a Vertcoin node up and running on a Raspberry Pi, Raspberry Pi Zero and Intel NUC. Along with information to get a Vertcoin node up and running was also optional steps to install p2pool-vtc. I decided that while this step by step guide might be helpful to a few, a setup script may prove to be useful to a wider range of people. I have this script to a point where I think it may be productive to share with a bigger audience, for those who are brave and have this hardware sitting around or like to tinker with projects; I invite you to test this setup script if you are interested, if you run into errors any sort of verbose console output of the error proves to be extremely helpful in troubleshooting. The script was designed to produce a “headless” server... meaning we will not be using a GUI to configure Vertcoin or check to see how things are running. In fact, once the server is set up, you will only interact with it using command line calls over SSH. The idea is to have this full node be simple, low-power, with optimized memory usage and something that “just runs” in your basement, closet, etc. Why run a headless node on a Single Board Computer?
You want to support vertcoin. Running a node makes the network more robust and able to serve more wallets, more users, and more transactions.
You are building or using applications such as mining that must validate transactions according to vertcoin’s consensus rules.
You are developing vertcoin software and need to rely on a vertcoin node for programmable (API) access to the network and blockchain.
The idea is to have this full node be simple, low-power, with optimized memory usage and something that “just runs” in your basement, closet, etc. Required: USB Flash Drive 6GB - 32GB Please note that the script was designed for Single Board Computers first and looks for an accessible USB Flash Drive to use for storing the blockchain and swap file, as constant writing to a microSD can degrade the health of the microSD. Supports
Raspberry Pi 3 B+ | ARM Cortex-A53 1.4GHz | 1GB SRAM |
Raspberry Pi Zero (W) | Single Core ARMv6 1 Ghz | 433MB RAM |
All of the hardware listed above is hardware that I have personally tested / am testing on myself. The plan is to continue expanding my arsenal of single board computers and continue to add support for more hardware to ensure as much compatibility as possible. Functionality
Installs Vertcoin full node to Single Board Computer
Installs p2pool-vtc (Optional)
Installs LIT and LIT-AF (Optional)
It is worth noting that LIT can be ran with multiple configurations, the ones displayed in the Post Installation Report reflect values that run LIT with the Vertcoin Mainnet. Please be aware that the Vertcoin Testnet chain has not been mined 100% of the time in the past, if you make transactions on the Vertcoin testnet that do not go through it is likely because the chain has stopped being mined. BE CAREFUL WITH YOUR COINS, ONLY TEST WITH WHAT YOU ARE OKAY WITH LOSING IF YOU USE THE MAINNET.
Recommended: Use Etcher to install the chosen OS to your microSD card / USB flash drive.
If you intend on installing Ubuntu Server 16.04 to your Intel NUC please use Etcher to install the .iso to your USB flash drive. https://etcher.io/ PLEASE NOTE THIS SCRIPT MAY GIVE AN ERROR. THIS IS THE NATURE OF TESTING. PLEASE REPORT YOUR ERRORS IF YOU WANT THEM TO BE FIXED/RESOLVED. THANK YOU FOR BETTERING THE DEVELOPMENT OF THIS SCRIPT.
You can use different clients to ssh into your node. One option is using PuTTY or Git Bash on Windows which is included in the desktop version of Git. If you are using Linux you can simply open a new terminal window and ssh to the IP address of your node (hardware you intend installing the Vertcoin node on). You will need to know the IP address of your node, this can be found on your router page. ssh 192.168.1.5 -l pi For example, this command uses ssh to login to 192.168.1.5 using the -l login name of pi. The IP address of your node will likely be different for you, in this example I am logging into a Raspberry Pi which has a default login name of pi. A brief list of commands that can be used to check on the Vertcoin node status: vertcoin-cli getblockchaininfo | Grab information about your blockchain vertcoin-cli getblockcount | Grab the current count of blocks on your node vertcoin-cli getconnectioncount | Grab the current count of connections to your node. A number of connections larger than 8 means that you have incoming connections to your node. The default settings are to make 8 outgoing connections. If you want incoming connections please port forward your Raspberry Pi in your Router settings page. vertcoin-cli getpeerinfo | Grab the information about the peers you have connected to / are connected to vertcoin-cli getnettotals | Grab network data, how much downloaded/upload displayed in bytes tail -f ~/.vertcoin/debug.log | Output the latest lines in the Vertcoin debug.log to see verbose information about the Vertcoin daemon (ctrl+c to stop) Thank you to all who have helped me and inspired me thus far, @b17z, @jamesl22, @vertcoinmarketingteam, @canen, @flakfired, @etang600, @BDF, @tucker178, @Xer0 This work is dedicated to the users of Vertcoin, thank you for making this possible. 7/20/2018 Thank you @CommodoreAmiga for the incredibly generous tip <3 You can reach me @Sam Sepiol#3396 on the Vertcoin Discord, here on reddit or @ [email protected]
Getting frustrated with Ubuntu. Are my experiences the norm for a Linux user?
Let me start off by saying that I'm not a total newb, but still pretty green. I like to believe I'm capable with computers, and know enough to figure out most issues. I also have a pretty solid general understanding of how they function. Been a Windows user most of my life, but decided to make the switch to Linux a few years back. My experiences thus far are making me reconsider the switch, despite the fact that I've really become opposed to using Windows. I'm curious if I should expect more of the same indefinitely, or if my experiences up to this point are unusual, and I should expect to reach a point where I can just use the OS, instead of spend hours trying to perform every task. It all started when I downloaded Ubuntu about three years ago. I easily got it installed as a dual boot on a Windows machine. Had to start by allocating disk space in Windows for the new Linux install, prepared a live usb, went through the install, cake. Then I started trying to do stuff, like use a printer. Well HP doesn't make a driver for Linux and, probably, 2-4 hours of research led to me still not having a working printer. I found a driver, but the process to get it installed did not work as it was supposed to. I forget the specifics, but I followed a tutorial to the T, but ran into unforeseen installation issues, and never could figure out how to get the process complete. After that I started running into issues with the FireFox browser. I've alwasy used FF on Windows with no issues. On Ubuntu it ran slower than dial-up from the mid-90's. Again, 2-4 hours worth of research and several changes to things like FF settings, disabling add-ons, etc., and I still had no fix. Still I wasn't deterred. Then the dual boot broke. I tried boot repair. No dice. Tried for several hours to get it working. Asked about it on forums, sent in results of boot repair (where I forget) only to get no response, and finally I threw in the towel. I also struggled to get Bitcoin Armory working, with some very frustrating success, but I didn't count that against Linux, since it was very new software, and I wasn't surprised it was buggy. Fast forward to today. I've been using Windows for a couple years, with few attempts made to use Linux, except for trying to retrieve a very small amount of BTC from Armory, which consumed about three weekends of my life to finally achieve. Now I've decided to give it another go. I downloaded UbuntuStudio b/c I'd like to use some of the music production software that comes with it. Following some tutorials online, I tried to connect my midi keyboard to the computer using QJackCtl. I couldn't remember the issue that I ran into when starting to type this up, so I tried to repeat the process, only to have the program crash during start up, three times. The computer had literally just restarted 20 minutes ago, so I doubt a reboot would work, but maybe. It's almost funny at this point. I'm really disappointed that I can't get the audio software that came with the distro working "fresh out of the box." Maybe with a few hours, or weekends, worth of research? I've also been getting a system error message every time I login. I posted a query on the Ubuntu forums. That issue has yet to be sorted out. I hesitate to include this next part, because it involves software that is really still in it's early stages, and I'm trying to be realistic in taking the perspective that any problems I encounter are with the new software, not Ubuntu, but the fact that I had zero problems getting the same stuff to work in Windows just adds to my frustration with Ubuntu. Everything I'm about to describe is involved with installing monero mining and wallet software. The exception is the AMD drivers needed for the GPU I'm using to mine. Those I expected to work without issue. I followed the directions for installing the AMD drivers for Ubuntu on the AMD website, and the program would not work. After, you guessed it, 2-4 hours of research, I finally, almost by accident, installed an older version of the driver software. Boom, it worked. WTF man?! When I installed the Windows version it took 2 minutes. Moving on, I tried getting the xmr-stak mining software working. This took me several hours, spread over several days to sort out. Same with the monero-gui wallet, which actually I've only got half-way working. In fact, I've tried installing the monero-gui by two different ways. In the process I've inadvertently got the monerod daemon running, but not the gui. Actually, the monerod daemon starts with the computer and I haven't even started trying to figure out how to turn that off, since what's the point of having it run if I can't use the gui? In Windows I had all of this up and running in a couple of hours. And in saying that I'm prepared for the "if you like Windows so much then use that!" or "you're just too thick to figure it out!", but I don't like Windows, and I don't think it's a matter of not figuring it out. It seems to me that the reason I've spent dozens of hours just trying to get things to work in Linux is that nearly every time I've tried to do something, there is inevatably some error along the way where following the directions isn't good enough, and sorting out the issue is a feat in and of itself. I just want to know if this is unusual, or if this is how it's going to go forever if I keep using Linux. Is my experience typical? TL;DR: I've had a litany of issues and spent countless hours trying to fix them using Linux. Is this rare, and I've just had an unusual experience, or actually pretty common, and I should just accept it as the cost of using an open source OS?

So…I hope when they finally do get me, it’s obvious that they just made it up. I don’t go out of my way to make it easy.” – Cody Wilson For all Anarchists our love for freedom unites us and guides us. I recently had a conversation with a mutual friend that Cody and I have in common and he stated something very insightful: CryptoAnarchy is like the Lord of the Rings. You have to cooperate with people that you don’t know where they are or what they’re up to. That is, you just know that we are all figuring out at the same time on how to take down Sauron. Anarchy is guided by the natural instinct for self-preservation. You can trust that others are also actively working in keeping us all free. For us all to move into more synergistic cooperation we need more motivation. Nothing is more motivating than our movement away from an impending harmful evil. The persecution that Cody Wilson has gone through since he started his activism is testament to the evil that awaits the entire world if we do not fight against the impending digital global prison. Just note how easy it was to find Cody.Government indoctrinated brownshirts and surveillance are everywhere. As Jeff recently said in London, “CryptoAnarchy is about the cryptography.” Cryptocurrency is only possible due to the privacy offered by cryptography. A true cryptocurrency is completely fungible, anonymous, and private. Blockchains without on-chain privacy set by default, are dangerous and offer nothing other than accurate surveillance. That is, the moment you destroy a coin’s fungibility you corrupt its incentive structure. This is because you would then have two classes of the same coin within a transparent blockchain; these are coins that are “tainted” or “untainted” according to government. This differentiation created by blockchain surveillance leads “tainted” coins to be priced differently from “untainted” coins. Once this happens you destroy the functionality of a currency as a medium of exchange. Imagine the headache of retailers in having to tell clients that they only accept “untainted” bitcoins. The result of not having a fungible medium of exchange is that you destroy the incentive structure of the network effect of a coin. You simply end up with a useless and unwanted network where value is supposed to be exchanged. If the units within the medium of exchange do not themselves contain the same value in the market, the utility of the network effect is destroyed. The economic ramifications of non-fungible SurveillanceCoins are so bad that they make fiat currencies of central banks look good. In spite of their centralized proof of government violence, fiat currencies are more fungible and private than a coin based on a transparent blockchain. For much time within crypto we would call the majority of blockchains as “pseudo-anonymous” because we knew the importance of fungibility. At that time blockchain analysis had not caught up to our technology. Now companies like Elliptic and Chainalysis have made the vast majority of blockchains in the market transparent. Sadly, most blockchain communities have not upgraded their privacy to be on chain by default- making them transparent. However, some more intelligent communities- like Monero- are at the same time growing because they understand the importance of fungibility. Please understand that we at TDV are ahead of the pack in understanding where all of this is going. The vast majority of people won’t tell you these harsh truths about the Blockchain space, but it is our moral imperative to inform you as best as possible. As time goes on, we will continue to champion actual fungible CryptoCurrencies and we will continue to make clear distinctions between a SurveillanceCoin and an actual CryptoCurrency. It is important that we take a step back from CryptoCurrencies and focus on just cryptography. You can never be too careful. Throughout our groups we have had various requests as to how to better use different wallets. Yes, we will cover all of that in our upcoming surprise for our community, but what is most important is that you protect yourself at the network layer, your identity, and your communication. CryptoAnarchy began way before Bitcoin. If you want to know what will be happening to CryptoCurrencies and CryptoAnarchy in the near future, you need to read Timothy C. May’s 1992 prophetic Crypto Anarchist Manifesto. On reading this, you cannot afford to be idle regarding your privacy. This is not the time for you to easily give up what is most personal about you; your thoughts and identity. Your privacy is sacred. You need to protect your privacy as much as possible at all times. Don’t give into the defeatist notions of future technology being capable of deanonymizing any cryptography you currently use. Your goal is to be private right now in the present moment. You are up against a global digital tyranny- that is already here! ...Cazes was not a US citizen and the Alphabay servers and Cazes were not caught on US soil. Just because crimes involving narcotic deals took place in America, weirdly enough, the US seemingly has the right above anyone to seize Cazes’ property, and charge him and his accomplices in US trials... Use Secure Hardware That Protects You Be paranoid. Stay paranoid. The more paranoid you are the better. Currently the five eyes are moving to strip away all of your privacy. They are on the direct path to force all companies to hand over back doors to software and hardware encryption. This is a new breach on individual rights. The backdoors in hardware have existed since the 90’s via Trusted Computing and Digital Rights Management (DRM). The difference is that now companies will be fined and forced by governments (all governments) to open up backdoors for the surveillance of all- in both software and hardware. Australia is leading the charge since they are the only ones within the five eyes without a Bill of Rights. If you really want to be secure, then you need to start with your hardware. Almost all laptops and hardware chips are engineered with unsafe software. These chips can transmit voice, your networking, pictures, and even video signals. Many of these chips are used to install spyware, malware and viruses. The market has provided us with two easy plug-and-play hardware solutions. Purism is a CryptoAnarchist company dedicated in offering us the safest computers in the market. Purism’s line of Librem Laptops is manufactured with software and hardware built from the ground up, where you can be at ease knowing there are no back doors built within it. They work with hardware component suppliers and the Free software community in making hardware that respects and protects your security. Every chip is individually selected with emphasis on respecting freedom. (Purism Librem laptops have built in Kill-Switches for your microphone/camera and wireless/Bluetooth) All of the necessary components that you would have to bundle up together- by yourself- from a community vetted place like Prism-Break are already installed and ready to go within Librem laptops. Even if you were to install all of the necessary open-source encrypted alternatives, you still would not be able to 100% trust your current computer’s hardware. Purism Librem laptops come with their own PureOS (operating system). Purism also offers compatibility with Qubes OS in a flash-drive (similar to Tails) to give you even another layer of protection on top of PureOS. Qubes OS is what Edward Snowden uses. PureOs is a derivative of Debian GNU/Linux. Qubes is free and open-source software (FOSS). Purism is currently having a pre-sale for their first phone the Librem 5. Another popular safe hardware computer market alternative is ORWL. ORWL is a desktop PC. ORWL comes with a physical encryption key that looks like a keychain. If anyone ever tries to physically tamper with the ORWL computer, sensors will automatically detect the intrusion and erase everything. ORWL comes with the operating system options of Qubes OS, Ubuntu, or Windows. ORWL does not receive payment for their products in Crypto. Purism on the other hand accepts payment in BitcoinCore, BitcoinCash, Litecoin, Ethereum, Decred, Dogecoin, and Monero. ORWL is a good alternative for more computer savvy people. If you are not the most competent person with computers, Purism is the way to go. With Purism everything is ready to go. Once you get good hardware don’t use this new computer for anything other than crypto stuff. That is, don’t use it with anything that requires your slave identity. Don’t access social media with your name, don’t access bank accounts, don’t access crypto exchanges, don’t access old email accounts, definitely don’t access anything that requires KYC and AML, and don’t access any identifying log-in that is related to any of your previous internet identities. Create new identities from scratch for this new computer. Watch this video and learn about the basics on operational security (OPSEC). Take everything written here, and spoken at the conference in the video above, as barely the preliminary basic requirements of OPSEC. You should definitely continue your own research upon getting your new secure hardware computer. (It would be best if you purchased this computer using crypto- Monero preferably- and have it mailed to a mailing address not associated with any of your addresses; think along the lines of JJ Luna). Encrypt Your Communication “This generation being born now... is the last free generation.You are born and either immediately or within say a year you are known globally. Your identity in one form or another –coming as a result of your idiotic parents plastering your name and photos all over Facebook or as a result of insurance applications or passport applications– is known to all major world powers.” – Julian Assange The vast majority of our community uses Facebook. Unfortunately its network effect is something we all rely on to some degree. Fortunately for us a friend of our community created FaceMask. Through FaceMask we can still use Facebook in complete privacy- away from Zuckerberg's prying eyes. In the near future we will implement FaceMask into our TDV groups as optional privacy for our posts. We will provide our subscribers with the keys necessary to encrypt and decrypt the messages and posts. Again, this is optional. For now please go to the link above and familiarize yourself with Facemask and its technology. Don’t use Google. If you are using Google start transitioning out of it. If you are using Gmail, start moving towards encrypted services like ProtonMail or TutaNota. They both offer a free option, try them both out and choose your favorite. Use two factor authentication on everything that requires you to log-in that allows for the use of two factor authentication. Most people use Google Authenticator and Authy. I personally prefer the open source options of FreeOTP & andOTP. Use the one that you find best suited for you. Using one is paramount for security nowadays. If you are one that uses Google Docs with your team, move instead to CryptPad. The more you use CryptPad the more addicting it becomes; your collaborated work is encrypted and private. You no longer will have to worry about knowing that Google is capturing all of your collaborated work. You can also start using CryptPad for free. If you are using Skype for conference calls, switch to Jitsi. Jitsi is even easier to use than Skype. If you use their MeetJitsi feature you can just access the encrypted conferencing via any browser by agreeing with your other party on the same predetermined passphrase. Don’t use regular text messaging. Rather, use Signal, Wickr, Keybase, or Telegram. Use a VPN A VPN (virtual private network) encrypts all of your traffic via a private network of servers scattered throughout the world. This process anonymizes your IP address. Make sure you don’t use your identity when using a VPN- that would just give away your identity as being connected with the VPN servers you are using. Many VPN providers register your activity and can hand it over to government if they so demand it. They break their promises to their clients all the time. Let’s minimize risk by staying away from the most draconian of jurisdictions. To lessen this issue, do not ever use a VPN that is based out of any of the 5 eyes: -United Kingdom -United States -Australia -Canada -New Zealand Furthermore, avoid VPNs based out of the following nine countries, that combined with the first 5 make up the 14 eyes: -Denmark -France -The Netherlands -Norway -Germany -Belgium -Italy -Spain -Sweden No VPN is a complete safeguard. In spite of this, it is still best to use one. We recommend you ONLY use it (turn it on) when doing crypto-related things and only crypto-related things on your regular computer. For your new encrypted hardware computer have it on at all times. If you use it to access an actual bank account, or another personal account (including crypto accounts that require your personal information; read coinbase, or any other exchange) — then, again, the use of the VPN use becomes trite. Here are six VPN options outside of the 14 eyes that we recommend you research further and use at your own discretion: NordVPN (Panama) CyberGhost (Romania) HideMe (Malaysia) Astrill (Seychelles) TrustZone (Seychelles) iVPN (Gibralter) Like all things in the market now, some VPNs take Crypto as payment—others do not. It is best if you bought your VPN with crypto not not your credit card, debit card, or paypal. TOR(The Onion Router) The Onion Router is software that you use as a browser. It protects you by bouncing your communications around a distributed network- throughout the world- of relays runned by volunteers. This prevents evesdroppers from learning your IP address, spying on you, and disclosing your physical location. TOR also allows you to access sites that are blocked. You can use TOR and a VPN simultaneously. If you are new to all of this, it is best that you just learn how to use the features of your new computer coupled with your preferred VPN. The use of TOR is a little more complicated and you will have to configure it according the specifications of your preferred VPN. As you begin this process, as long as you are using your VPN correctly you should be fine. Fincen and crypto-exchanges ShapeShift is now stuck having to require its users to deanonymize their transactions in order to meet KYC and AML requirements; it pretty clear that they got ShapeShift under the Bank Secrecy Act. Stay away from Shapeshift (sorry @erikvorhees). “Very disappointed that @ShapeShift_io is implementing KYC. Just goes to show that any centralized entity will be pushed in that direction, which is why LN, atomic swaps and Decentralized Exchanges are the only way to resist a surveillance economics.” - Andreas Antonopoulos As the news of ShapeShift broke out, the market was quick to answer with alternatives. Among the private centric alternatives to ShapeShift we find Godex, ChangeHero, XMR.TO, and Bisq. ChangeHero and Godex are pretty much the same business concept as ShapeShift. The only difference is that they do not require you to become transparent. XMR.TO allows you to make BTC payments by using Monero. That is, by using Monero together with XMR.TO you can pay any BTC address in the world while protecting your privacy. Bisq is the Best Option The most important to focus on is Bisq. Bisq is a complete decentralized exchange. Bisq is instantly accessible- there is no need for registration or approval from a central authority. The system is decentralized peer-to-peer and trading cannot be stopped or censored. Bisq is safe. Unlike MtGox and the rest of centralized exchanges, Bisq never holds your funds. Bisq provides a system of decentralized arbitration with security deposits that protect traders. The privacy is set where no one except trading partners exchange personal identifying information. All personal data is stored locally. All communication on Bisq is end-to-end encrypted routed over Tor. Upon downloading and running Bisq TOR runs on Bisq automatically. Every aspect of the development of Bisq is open source. Bisq is easy to use. If you are accustomed to centralized exchanges, you might find Bisq a little different. If you want anonymity and privacy, this is the best crypto exchange we have. Tell your friends about Bisq. Just download Bisq and take it for a test drive, you will feel fresh freedom of entering into peaceful voluntary exchange with your fellow man. Do it, it’s good for the soul. On Cody I would like to personally thank all of our subscribers for generously donating to Defense Distributed on our last issue. At the moment of us putting out our last newsletter, DefDist had raised less than 100k USD. After our Newsletter got out, his donations went past 300k USD. Thank you very much for helping out our friends in their continual fight for freedom! Please pray for Cody, his friends, and his family. I once asked Cody what his background was- because idk his mannerisms have always been interesting to me. He answered; “I am Romani- I am a Gypsy.” Thank you for helping out our Gypsy friend and his band of rebels! They will very much be using your generous donations now that things got much more serious. If you haven’t donated, please consider donating. Blessings!
