The Monero Missives (weekly report) - September 16th, 2014
Original post is here Monero Missives September 15th, 2014 Hello, and welcome to our twelfth Monero Missive! This is our first Missive after a bit of a break whilst we thwarted two related blockchain attacks. Nonetheless, we have not sat by idly, we have been finalising and completing a brand new aspect of Monero designed to protect your privacy now and in the future: the Monero Research Lab Major Updates
The Monero Research Lab is an open collective and a multi-faceted academic group focused on the ongoing improvement of Monero. Membership is not fixed, and comes and goes as researchers become interested in Monero. This isn't a group focused on the addition of "features" to Monero, but rather the analysis and improvement of the underlying core of Monero to make sure that the theories and cryptography behind Monero continue to remain robust and sound. With that in mind, we are proud to announce the release of the first two publications out of the Monero Research Lab: MRL-0001 - A Note on Chain Reactions in Traceability in CryptoNote 2.0 - this is a research bulletin that investigates how a chain reaction could weaken the blockchain resistance properties of CryptoNote's ring signatures if low mixin values are consistently chosen MRL-0002 - Counterfeiting via Merkle Tree Exploits within Virtual Currencies Employing the CryptoNote Protocol - in this research bulletin we investigate how the block 202612 attack occurred and what it exploited, and also covers the permanent fix we have put in place
This week Friday we're going to have our second #Monero-Dev Fireside Chat this week Friday, September 19th, 2014, at 10:00 EST which is 14:00 UTC and 16:00 UTC +2. For a full table of the time zones you can refer to this image, or you can use this online tool to add your city and make sure you have the correct starting time. Please note that this is a developer event, and so most of the focus will be from that perspective.
To pick up where we left off with our last Missive, we are also happy to announce the availability of Monero merchandise on the Monero Gear store, powered by Zazzle. The advantage of us using Zazzle is that it is on-demand and we never have to worry about print runs or stock or anything. In return we get 15% of each sale as a "royalty" that will go towards enabling further Monero development, although Zazzle do not (yet!) accept Bitcoin or Monero. We hope to add new designs to the store on a regular basis. You can check the store out here: http://www.zazzle.com/monerogear* or take a peek at some of the new designs right here
We are also pleased to announce the release of URS, a Monero project written in Go that allows you to sign messages using ring signatures as part of a group. The signature can be verified, but it cannot be determined which one of the signatories in the group did the actual signing (just like Monero uses for transactional unlinkability!). You can take a look at the project here: https://github.com/monero-project/urs, and the Bitcointalk thread dedicated to the project is here: https://bitcointalk.org/index.php?topic=768499.0
We have a new tagged release, 0.8.8.4, available for download (binaries: Windows, Mac, Linux, FreeBSD). This adds the following features: Testnet: we now have an operating testnet. When using bitmonerod or simplewallet you can now use the --testnet flag to use testnet instead of mainnet. Feel free to run a mining node or just a testnet node, we will be setting up email alerts for testnet nodes when an update is pending (although having a few older testnet nodes on the network won't hurt testing). FreeBSD Compatability: Monero now works on FreeBSD out the box. We will add it to the ports tree soon. At the moment compilation is no different from regular Linux and Unix compilation, and the same dependencies apply. GPG commits: we have begun GPG-signing commits and merges. This is an important step in maintaining the integrity of the codebase, and will ensure that any compromise of our computers or even the github account won't allow a malicious attacker to push code to the repository without the unsigned commits being spotted. Verification can be done by running 'git log --show-signature', which will show and verify signatures. An example of what you should see can be found here Versioning: versioning is a lot easier, now, as tagged releases from 0.8.8.4 onwards will show version-final (eg. 0.8.8.4-final) as their version, and those built between tagged releases will show version-commithash (eg. 0.8.8.4-9088ea1). We expect this will greatly aid in debugging problems, as we can immediately pinpoint the actual version / commit a user is on. Logging: default log levels have been adjusted so that non-critical warnings are now relegated to log-level 1 and above. Apart from the normal reorganisation notifications, the only messages in red that should show up in the daemon are actual errors.
Dev Diary Core: because of all of the rapid changes that we had to merge into master to deal with the aftermath of the block 202612 attack, we have to bring the development branch in sync. At this stage the development branch should not be considered usable until the rebase is complete. Build: the big change is FreeBSD compatibility, as mentioned above. A more subtle change is that the build will now first look for miniupnpc on the local system, and use that if found. If it fails to find miniupnpc it will fall back to the local copy. Build: there is a new Makefile target, release-static, that builds statically linked binaries for redistribution. At this stage it forces 64-bit builds, once we have the embedded database working cleanly we can remove this. Wallet: per-kb fees are nearly complete, and will be deployed to testnet within the next week or so. Once some thorough testing has been done on testnet we can merge this into master, and transaction fees can return to "normal". Blockchain: this took a bit of a backseat with the blockchain attacks. Now that things are back to some semblance of normality, the first implementation can be written. We have chosen LMDB for the initial implementation, as this will allow us to rapidly write a Berkeley DB interface based off of it (they use similar APIs) and thus have a baseline for performance comparisons. Core: all non-critical "errors" and warnings have been moved to log-level 1. As a developer, you may find it useful to run log-level 1 or 2 as your default. Until next week!
Primecoin Profitability Calculations and mini Guide
So you want to mine Primecoins. See this analysis bellow for today : (30/11/2013) The current price of 1 Primecoin (XPM) = 0.00640010 Bitcoins (BTC) The current payout barrier for the only good pool (http://beeeeer.org) is 3.01 XPM 3.01 XPM equals to 0.0192003 BTC 0.0192003 BTC = 21.86 USD Your aim is to mine 3.01 XPM as fast as possible at current difficulty 9.985399019 To mine 3.01 Primecoins per 24 hours you need about 21 Chains Per Day. At this rate you can make 655 USD per month On my MacMini (2010) I can make 1 chain per day, On a big HP server with dual XEON I can make 2.5 chains a day On the 20 Core Droplet in Digital Ocean you can make 2.6 chains a day You would need about 8 of those machines to achieve this. (This means that you would need 2 accounts as there is a 5 droplet limit per account). When you signup you pay $5 through paypal and get a bonus of $10 if you use the code "LINUX13" during checkout. The cost to operate those machines for 24 hours is : 0.941 x 24 x 8 = $180 $-180 cost - $10 bonus + $5 deposit + $21.86 = -$163 profit This means that you do not make profit currently, but you could always signup, pay the paypal fee and have the machines on until they suspend you since you do not setup any credit card or auto payment but this will be a one off and get you started with some coins that you can trade in cryptsy. You can always sell the BTC at like double price in small increments in ebay and make up for the losses but it does not worth the hassle At the current trends it looks like primecoin will rise , at least triple, and in combination with the bitcoin price rise it might worth mining or at least setup the infrastructure to mine. Personally I have destroyed all my droplets and keep them on standby and wait for the price to rise. I have an image ready that can restore to any droplet i create to start mining whenever I want. Trying to be pro-active. I am using some work PCs and old server that you can buy for like 200 on ebay to make those 3XPMs a day currently. Lastly here are the commands to start mining on a ubuntu 13 x64bit when you get your hands on. Login as root, do a sudo -s and then mkdir ~/.primecoin echo "rpcuser=none rpcpassword=none gen=1" > ~/.primecoin/primecoin.conf sudo apt-get update sudo apt-get install bzip2 -y sudo apt-get install git -y sudo apt-get install git-core -y sudo apt-get install subversion -y sudo apt-get install checkinstall -y sudo apt-get install build-essential -y sudo apt-get install libssl-dev -y sudo apt-get install libboost-all-dev -y sudo apt-get install libdb5.1-dev -y sudo apt-get install libdb5.1++-dev -y sudo apt-get install libgtk2.0-dev -y sudo apt-get install libgmp3-dev -y wget http://sourceforge.net/projects/primecoin-hp/files/0.1.2-hp11/primecoin-0.1.2-hp11.tar.bz2/download tar jxvf download cd primecoin-0.1.2-hp11 cd src make -f makefile.unix USE_UPNP=- ./primecoind -pooluser=AUd61zfP6oM6LicMkwtxsn1TU8R4ZdLJ9Z -poolpassword=0 -poolip=184.108.40.206 -poolport=1337 -genproclimit=20 & watch -d -n 5 './primecoind getmininginfo && ./primecoind getdifficulty && ./primecoind listtransactions "*" 1 0' (make sure you replace the mining address above with your mining address) That is all for today , I hope some people find it useful :)
Now since mining gets more difficult with time your best option will be to run 4 more of the same thing to mine quickly.
Each server costs $20. So $20*5 = $100. $100/30 = $3.33 each day You have $10 credit so you have ~3 days worth of mining that you can do for free. If you go over you will only be be charged the extra by the hour so don't worry about getting a huge charge on your creditcard unless you forget for a month. WHAT IF I WANT BITCOINS OR ANOTHER CURRENCY NOT PROTOSHARES? Well you can try to find other guides online to use these servers, but unless it is a CPU only coin the results won't be worth it. You can also trade them on Cryptsy for other coins including bitcoins. Cryptsy non-refferal
Learn how to build and maintain your own altcoin cryptocurrency mining pool, including how to compile coin daemons under Linux, add coins to a pool, and how to earn commission from everyone who mines at your pool. Lots of demos that you can follow yourself as you build your own mining pool. Build Bitcoin Unix . Mar 30, 2018 DTN Staff. twitter. pinterest. google plus. facebook. Bitcoin Core Version 0.16.0 Released 26 February 2018 Bitcoin Core should also work on most other Unix-like systems but is not as frequently tested on them. It is not recommended to use Bitcoin Core on unsupported systems. From Bitcoin Core 0.20.0 onwards, macOS versions earlier than 10.12 are no longer supported. If we have a lot of request coming in, we will process this until the queue is empty. The reason why I have done this is to be able to shutdown the bitcoin process. 0mq does not any authentication method. That's correct. Only allow it from trusted sources.
