[MINING] Can anyone help with this? "stratum_subscribe timed out ...retry after 10 seconds"

Hi everyone,
Just as a disclaimer for the beginning, I'm not investing in Bitcoin, I'm not doing this for any profit or reason, it's more for my own interest.
I'm trying to do some mining on my Raspberry Pi 3, and I have set up a wallet, got a pool account with Slush Pool, and installed or the libraries and software needed to run. As far as I am aware I have ran the right code. However, when I run it, I get this:
 ./cpuminer --algo sha256d --url stratum+tcp://eu.stratum.slushpool.com:3333 --user CENSORED --pass CENSORED ** cpuminer-multi 1.3.7 by [email protected] ** [2020-05-18 21:25:38] Starting Stratum on stratum+tcp://eu.stratum.slushpool.com:3333 [2020-05-18 21:25:38] 4 miner threads started, using 'sha256d' algorithm.

Asicpower AP9-SHA256 Review


Asicpower AP9-SHA256 Review

Bitmain is regarded as one of the most influential companies in the ASIC mining industry. It is estimated that they have manufactured approximately 53% of all mining equipment.Without including their mining profits, that’s around $140 million dollars in sales. These figures are staggering, but Bitmain’s monopoly of the Bitcoin ASIC market may come to an end, following the release of PowerAsic’s asicpower AP9-SHA256.

About the asicpower AP9-SHA256

Designed with brand new technology and boasting 94 TH/s per miner, the AP(-SHA256 is the most powerful and efficient Bitcoin miner to date.PowerAsic claims they spent $12 million dollars on research, development, and prototypes.PowerAsic also noted that their miners take advantage of ASICBOOST, an exploit of Bitcoin’s algorithm which improves mining efficiency by 20%.An unusual approach separate Powerasic’s miner to the other manufactures is the implementation of copper heat-sink claimed to have a superior thermal conductivity 69% better than aluminium. Don’t take their words for it but confirm the facts are correct on widely well known and published science documents as this one.The first batch of miners were announced and made available for order in August of 2019, with start scheduled for shipment in September, 2019.
Powerasic claims that the machines are around 40 percent more productive than the most proficient ASIC on the market, Bitmain’s Antminer S17.According to PowerAsic, they started a mining project with the aim to bring much needed competition to the market…We want to ‘make SHA256 great again.Sitting at the hefty price of $2,795.00, the powerasic AP9-SHA256 is far from affordable for the average person. Fortunately, due to the newly born rivalry between Bitmain and Powerasic, the price will probably lower with time and competition.The power supply for this unit is included and integrated in the top-box also including the controler card as a one unit. You will also get standard power cable, network cable, manual and software in the packet. In comparison to the price of the Antminer S17 , the Powerasic AP9-Sha256 is a better value.

Power Supply

The integrated PSU 3300W has a inputVoltage 220V 50Hz 30A. There are 2 fan 40mm., 1 fan 60mm to keep it cool and the power cable 3 legs following CEE 7 standard.Professional mining hardware runs optimally at 220-240V, hence why mining farms step down their own electricity supply to 220-240V. Note that 220V current is only found outside of the US – American outlets are 110V by default. Unless you want to hire an electrician, this could cause some people trouble adapt to the eficient and recomended 220V power needed, still 110V will get the job done, but they are not ideal for optimum mining performance.

Power Consumption

Thanks to the powerasic AP9-HA256’s new 7nm generation of ASIC chips, the AP9-SHA256 has become the most electrically-efficient miner on the market.Consuming merely 30.J/TB, or 2860W from the wall, the 16T is 30% more electrically-efficient than the Antminer S17.

Profitability

Powerasic ’s new ASIC technology is impressive. When compared to its closest competitor, the Antminer S17, the powerasic AP9-HA256 is the clear winner. It hashes at 94 TH/s, as opposed to the S17’s 56 TH/s. Moreover, the the AP9-HA256 consumes 30J/GH, whereas the S17 consumes 39-45J/TB.The difference in power consumption is miniscule, but when it comes to large-scale mining, the the AP9-HA256’s edge will drastically increase the profitability of a mining operation. This ASIC is profitable not only for mining on a large scale, but for the individual miner as well.Take a look at the projected mining profitability of a single miner:Note that is appears profitable even with high electricity costs ($0.1 per KW/h). With $0.05 / KW/h it’s even more profitable:📷Each powerasic AP9-HA256 will generate about $6,009 per year (calculated with 1 BTC=$10,141.5). Mining profitability may vary. You can usethis free profitability calculator to determine your projected earnings.

Is powerasic AP9-HA256 a Scam?

There is been a lot of talk on Twitter that powerasic AP9-HA256 is a scam. It appears it is not, as many users are already claiming to have received their miners.Slush, the creator ot Slush Mining Pool and the TREZOR hardware wallet, claims on Twitter that he has seen units and knows people who have had their miners delivered:

Verdict: Is The Antminer S17 Outdated?

When the first batch of Bitmain’s Antminer S17 ASICs reached the eager hands of miners, they were all the rage. The S17 was renowned as the most efficient ASIC miner on the market. Many used the S17 as the industry’s golden standard.Up until the launch of the powerasic AP9-HA256, it was the golden standard.But, now?Things have changed.Not only is the powerasic AP9-HA256 more powerful than its predecessor from Bitmain, but also more efficient, and therefore, more profitable.Ever since the announcement of the new ASIC, there was widespread speculation of its legitimacy – and rightly so.The Bitcoin community has been plagued with small, phony companies manipulating images of preexisting antminers as a ploy to hype up their fake products. Nevertheless, powerasic AP9-HA256 is taking things seriously, and their first batch of miners have lived up to expectations.The fact of the matter is, Bitmain’s most powerful and efficient antminer has been dethroned by the new reigning king of ASICs: The powerasic AP9-HA256.

Conclusion

Bitmain has dominated the ASIC market since its inception in 2013.There are a few other companies producing ASICs. However, before the creation of PowerAsics AP9-SHA256., Bitmain was the only company with a proven track record that sold efficient miners directly to the public.Powerasic AP9-HA256 has the potential to bring Bitmain’s monopoly to an end. Powerasic AP9-HA256 has a bright future ahead of them. Now that Bitmain has noteworthy competition, it will be interesting to see how it affects the market. The powerasic AP9-HA256 is the best option (for now) for anyone getting started with mining. Powerasic’s innovation should force other ASIC producers to innovate and force other companies to release new miners with better efficiency. So whether you’re buying a miner now or soon, you’re likely to benefit from the development of this new miner. For more, Visit Us: https://asicpower.net/product.php

November BTC Fork - The Facts

Update 2: THE NOVEMBER SEGWIT2X HARDFORK HAS NOW BEEN CANCELLED! :D
Update: Thank you for your appreciation on this article. I decided to publish it on Medium.  
You can find the article on this link.
 
Existing Article:
With less than a dozen days left before the SegWit2X fork, I thought I'd start gathering some facts before I start forming personal opinions and speculative conclusions. I refer to the SegWit1X chain as 1X and the SegWit2X chain as 2X for simplicity, and I have looked for very simple facts and safe assumptions. Here are the dots that I gathered:  
 
• Fork at Block 494,784. Approximate time = 16th of November - see Reference 6 for exact time.  
 
The New York Agreement: The NYA involved parties representing about 83% of the then hashing power who all agreed to both hardforks - one for SegWit and another for an increased block size of 2MB (2X) within 6 months of the former. Further details in reference 1.  
 
• It is safe to assume that miners will only mine the most profitable chain (possibly several chains in differing proportions).  
• If whales pump a single chain it will gain more value. If this happens, miners will be more inclined to mine that particular chain only. This will result in the other chain(s)potentially losing overall mining attractiveness.  
 
1X will continue to have a 1MB block and SegWit;  
2X will have a 2MB block and SegWit;  
Bitcoin Cash (Just for info right now) currently has an 8 MB block with NO SegWit;  
 
Current Price Status (Futures) on BitFinex: 2X/BTC = 0.17; 1X/BTC = 0.83  
 
Current Mining Status: 2X = Around 85% of blocks are signalling for 2X.  
It seems only a few mining pools including Slush Pool, F2Pool and Kano CKPool are not signalling Segwit2X. All Antpool (Jihan Wu) owned pools are signalling for Segwit2X and will likely continue to do so up to the fork. It is not clear if any other pools from the Segwit2X signalling group will change their minds in the meantime.  
 
Lower mining power chain: Likely to be 1X. Fees likely to be extremely high as not many miners. Difficulty adjustment could take a few weeks, if not months. Until then it will be very difficult to transfer funds. [It may be better to keep BTC on an exchange before fork, to ease liquidity cost/time if you want to sell either of the coins immediately]  
 
Double-spending: Miners (from 2X) will have an ability and incentive to double-spend on the minority chain (lower mining power chain). If you have huge mining power, you can allocate some of it to just double-spend on the minority chain. Some people will possibly lose confidence in the minority chain as a result.  
 
Replay-Protection: Neither 1X nor 2X currently have replay protection.  
 
Exchanges:
  1. Bitfinex: original chain is “BTC”, SegWit2x chain is “B2X”  
  2. BitMEX: Original chain is BTC  
  3. Bitstamp: Unknown  
  4. GDAX & Coinbase: hash power and market cap decides which chain is “BTC”  
  5. Kraken: Unknown  
  6. HitBTC: original chain is “BTC”, SegWit2x chain is “B2X”  
  7. CoinsBank: Original chain is BTC  
  8. CEX.IO: original chain is “BTC”, SegWit2x chain is “B2X”  
  9. Gemini: hash power decides which chain is “BTC”  
  10. Coinfloor: Unknown  
  11. BTCC (Updated on Twitter): BTCC will consider which of 1MB and 2MB to name as #bitcoin based on market feedback and adoption.  
Further details in reference 4.  
 
The OPINIONs section
Vinny Lingham's opinion: 2X will outcompete 1X.  
 
Enter Bitcoin Cash: A review by Ryan X. Charles who has incorporated some of Vinny Lingham's quotes, states the following:  
 
a. BCH is a fork of BTC with same PoW, but with improved Difficulty Adjustment Algorithm (DAA). BCH cannot die, but 1X and 2X could both die. If whales shift most of their holdings to BCH (or another coin), that would incentivise the miners to mine BCH (or another coin) instead of 1X and 2X. Both 1X and 2X would lose their mining power; however Core would release an emergency update to software adding DAA like BCH (or another coin). Thus, 1X would survive, and 2X (which might not get DAA) would die.  
 
b. If 2X continues to be the dominantly mined chain, 1X will be forced to launch an emergency update to their PoW with DAA. There could be fighting between the two chains, and as a result a struggle to become dominant potentially causing altcoins to flourish.  
 
My observations
BCH is upgrading their EDA (Emergency Difficulty Adjuster) on Nov 13. See website. This will lead to reduced volatility in BCH - likely making it more attractive to more long-term miners.  
 
Mining profitability: It is currently almost equally profitable to mine either BTC or BCH.  
 
• What to keep and eye on before the fork to judge yourself where the fate of BTC is heading.  
  1. Mining signalling distribution
  2. DAA: 1X or 2X software updates to implement Difficulty Adjustment Algorithms
  3. Futures price before fork
  4. Significant whale movement

AsicBoost and the strange case of CVE-2017-9230

About CVEs

In the public interest of tracking and remedying cybersecurity vulnerabilities quickly, a public database was created in 2000: the CVE List [1].
CVE stands for Common Vulnerabilities and Exposures. Its database records, known as CVEs, track and record publicly known cybersecurity vulnerabilities. Each recorded vulnerability has a unique ID and lifecycle where it follows certain states.

The AsicBoost controversy

In April 2017, Greg Maxwell published an email [2] on the bitcoin-dev mailing list which described AsicBoost - a patented optimization to the algorithm used in Bitcoin mining - as an attack on the Bitcoin protocol.
There was much contention [3] about whether AsicBoost constituted some kind of harmful exploit, or whether it was merely a technological innovation which enabled more efficient mining hardware (ASICs).
There were allegations, widely reported in media, that the patent served the interest of Bitmain [4]. The purported benefits of exploiting this patent as alleged by Core developers were contemporaneously disputed by other miners [5].

CVE-2017-9230 raised against AsicBoost

On 18 May 2017, Cameron Garnham posted to the bitcoin-dev list [6], urging for getting a CVE assigned to the perceived vulnerability.
On 24 May 2017, this CVE was created as CVE-2017-9230 [7]. It was simultaneously published under Bugtraq ID 'BID 98657' at [8].
The justification in the CVE stated that the AsicBoost method
'violates the security assumptions of (1) the choice of input, outside of the dedicated nonce area, fed into the Proof-of-Work function should not change its difficulty to evaluate and (2) every Proof-of-Work function execution should be independent.'
It seemed a plausible enough reasoning for the CVE to be assigned. It was entered in the list of Bitcoin-related CVE's at [9]. Detailed information on this particular CVE is still missing/incomplete on the wiki page, a year after the CVE was raised.

What happened since the CVE was raised

If you've followed along, you've learned that the CVE was raised to counter the exploitation of the AsicBoost method by miners.
Since then, however, a Core developer, BtcDrak, has been involved in the founding of a mining company, Halong Mining. Several online sources state his (part?) ownership of this company.
BtcDrak has put forward a proposal [10] which would enable the use of AsicBoost within the Bitcoin Core software (the dominant client software on the BTC network).
This proposal appears to directly contradict the CVE claims of how AsicBoost violates "security assumptions" of Bitcoin, and indeed does not address how it mitigates them, nor is CVE-2017-9230 referenced in any of its related documentation.
While the proposal's specification [11] and implementation [12] have not yet been formally accepted, the situation is that Halong has shipped mining equipment which is now actively employing AsicBoost [13,14] on the Bitcoin (BTC) network. There is even a website showing the blocks where AsicBoost was used [15].

Conflict of interest

There a clear conflict of interest in the actions of the Core developer BtcDrak. His actions as a Core developer appear to be furthering his company's interests and competitive advantage in the mining industry by exploiting a vulnerability of which he must have been keenly aware, having participated on the same bitcoin-dev mailing list where it was discussed.
The CVE was vociferously used to paint Bitmain as culpable for delaying Segwit (Bitmain was accused of using AsicBoost and blocking Segwit activation for their own profit motive - claims that Bitmain has publicly denied strongly and which were never substantiated).
One might have expected a similar outcry against Halong's proven and announced use of AsicBoost, but the parties that had previously condemned Bitmain remained mostly silent. Only an anonymous non-developer, Cobra-Bitcoin, co-owner of the bitcoin.org domain, spoke out on the Github pull request in [11], and Core developer Luke-jr spoke out against the use of the proposal on the Bitcoin network while consensus had not been reached on it [16].
Subsequent discussion on the bitcoin-dev list on this topic since March has been minimal and only concerned with technicalities of stratum protocol changes.

The bigger elephant in the room

It seems logical that either AsicBoost constitutes an exploitable weakness, and thus merits a CVE and measures taken to prevent its use on the Bitcoin network entirely.
Or it is not a problem and the CVE should be invalidated.
The Bitcoin Core project should use its consensus processes to arrive at a coherent decision.

Other problems raised by the use of overt AsicBoost

The Halong implementation uses version rolling of the nversion bits of the header. It reserves a subset of those bits for overt AsicBoost.
These bits are no longer available to BIP9, but there was no update of BIP9 proposed to address this impact.
This is a question of sensible procedures being followed (or not). The author did not find any review comment mentioning the lack of BIP9 specification update, which suggest a lack of thorough review on a proposal which dates back several months.
A minor issue is that the Core implementation warns when a certain proportion of unrecognized version bits are detected. This behavior can be triggered by the AsicBoost method used on the network.

BOARD
 
Paul Wasensteiner (aka Singularity).
I have been a Bitcoiner (now Casher) since mid-2011 when I discovered Bitcoin shortly after the first $30 price bubble. Since then, I have been highly active in the community, although it wasn't until this year that I dove into Bitcoin full time. I started the BTCforks initiative last year with Freetrader, which was a precursor to the Bitcoin Cash initiative. Until recently, I spent my time in the community trying to correct misinformation and educate newcomers. After Bitcoin Cash successfully launched, I decided to make a positive change and instead put my energy into pushing Bitcoin Cash forward. I have a wide range of experience and expertise, and have had two businesses of my own in the past. I am working towards changing the world for the better, and I feel Bitcoin Cash is one way of achieving this. I launched the Bitcoin Cash Fund initiative on 14th, November 2017 to expand Bitcoin Cash adoption.
 
Ian Descôteaux (aka checksum0/FractalGlitch).
Ian found out about bitcoin on January 3rd, 2010 after reading a piece on it. He spent time CPU and GPU mining, both solo and with Mining Team Reddit and Slush. After a break from Bitcoin, he reinvested in mining when the Bitmain S1 was released, and has kept this endeavor going ever since. It was at this time that fees started to increase and he realised that this may become an issue in the future. Today he owns and operates a private 4 MW mining facility in North America. Bitcoin Cash is the plan he signed up for when he first got into the bitcoin space.

Haipo is the CEO and founder of ViaBTC. He graduated from Northwestern Polytechnical University of China in 2012, majored in mathematics. After graduation he worked as a developer at Tencent Weibo (China’s Twitter) and then FUTU, a Tencent-invested Hong Kong stock exchange. YANG is one of the earliest adopters and investors of Bitcoin and has in-depth understanding in blockchain technology. YANG began to be involved in Bitcoin in 2013. Between 2014 and 2015, YANG started his career in cryptocurrency industry and led the R&D team at ZeusMiner, the former TOP3 Scrypt miner in the world. In April 2016, YANG committed himself to the development of ViaBTC Bitcoin pool and released the initial version after two months of extensive coding effort.

The November BTC Fork and Bitcoin Cash - The Facts

Update: Thank you for your appreciation on this article. I decided to publish it on Medium.  
You can find the article on this link.
 
Existing Article:
With less than a dozen days left before the SegWit2X fork, I have started gathering facts before I start forming personal opinions and speculative conclusions. I refer to the SegWit1X chain as 1X and the SegWit2X chain as 2X for simplicity, and I have looked for very simple facts and safe assumptions. Here are the dots that I gathered:  
 
• Fork at Block 494,784. Approximate date = 16th of November.  
 
The New York Agreement: The NYA involved parties representing about 83% of the then hashing power who all agreed to both hardforks - one for SegWit and another for an increased block size of 2MB (2X) within 6 months of the former. Further details in reference 1.  
 
• It is safe to assume that miners will only mine the most profitable chain (possibly several chains in differing proportions).  
• If whales pump a single chain it will gain more value. If this happens, miners will be more inclined to mine that particular chain only. This will result in the other chain(s)potentially losing overall mining attractiveness.  
 
1X will continue to have a 1MB block and SegWit;  
2X will have a 2MB block and SegWit;  
Bitcoin Cash (Just for info right now) currently has an 8 MB block with NO SegWit;  
 
Current Price Status (Futures) on BitFinex: 2X/BTC = 0.17; 1X/BTC = 0.83  
 
Current Mining Status: 2X = Around 85% of blocks are signalling for 2X.  
It seems only a few mining pools including Slush Pool, F2Pool and Kano CKPool are not signalling Segwit2X. All Antpool (Jihan Wu) owned pools are signalling for Segwit2X and will likely continue to do so up to the fork. It is not clear if any other pools from the Segwit2X signalling group will change their minds in the meantime.  
 
Lower mining power chain: Likely to be 1X. Fees likely to be extremely high as not many miners. Difficulty adjustment could take a few weeks, if not months. Until then it will be very difficult to transfer funds. [It may be better to keep BTC on an exchange before fork, to ease liquidity cost/time if you want to sell either of the coins immediately]  
 
Double-spending: Miners (from 2X) will have an ability and incentive to double-spend on the minority chain (lower mining power chain). If you have huge mining power, you can allocate some of it to just double-spend on the minority chain. Some people will possibly lose confidence in the minority chain as a result.  
 
Replay-Protection: Neither 1X nor 2X currently have replay protection.  
 
Exchanges:
  1. Bitfinex: original chain is “BTC”, SegWit2x chain is “B2X”  
  2. BitMEX: Original chain is BTC  
  3. Bitstamp: Unknown  
  4. GDAX & Coinbase: hash power and market cap decides which chain is “BTC”  
  5. Kraken: Unknown  
  6. HitBTC: original chain is “BTC”, SegWit2x chain is “B2X”  
  7. CoinsBank: Original chain is BTC  
  8. CEX.IO: original chain is “BTC”, SegWit2x chain is “B2X”  
  9. Gemini: hash power decides which chain is “BTC”  
  10. Coinfloor: Unknown  
  11. BTCC (Updated on Twitter): BTCC will consider which of 1MB and 2MB to name as #bitcoin based on market feedback and adoption.  
Further details in reference 4.  
 
The opinion section
Vinny Lingham's opinion: 2X will outcompete 1X.  
 
Enter Bitcoin Cash: A review by Ryan X. Charles who has incorporated some of Vinny Lingham's quotes, states the following:  
 
a. BCH is a fork of BTC with same PoW, but with improved Difficulty Adjustment Algorithm (DAA). BCH cannot die, but 1X and 2X could both die. If whales shift most of their holdings to BCH (or another coin), that would incentivise the miners to mine BCH (or another coin) instead of 1X and 2X. Both 1X and 2X would lose their mining power; however Core would release an emergency update to software adding DAA like BCH (or another coin). Thus, 1X would survive, and 2X (which might not get DAA) would die.  
 
b. If 2X continues to be the dominantly mined chain, 1X will be forced to launch an emergency update to their PoW with DAA. There could be fighting between the two chains, and as a result a struggle to become dominant potentially causing altcoins to flourish.  
 
My observations
BCH is upgrading their EDA (Emergency Difficulty Adjuster) on Nov 13. See website. This will lead to reduced volatility in BCH - likely making it more attractive to more long-term miners.  
 
Mining profitability: It is currently almost equally profitable to mine either BTC or BCH.  
 
• What to keep and eye on before the fork to judge yourself where the fate of BTC is heading.  
  1. Mining signalling distribution
  2. DAA: 1X or 2X software updates to implement Difficulty Adjustment Algorithms
  3. Futures price before fork
  4. Significant whale movement

Formal dispute of CVE-2017-9230 (claimed Bitcoin vulnerability due to AsicBoost)

%begin
27 May 2018
BtcFork hereby registers a formal dispute of CVE-2017-9230. The CVE list will be notified accordingly.
Our view is that what has been described in CVE-2017-9230 as an "attack methodology" is a benign mining optimization.
Since the CVE was raised, a Bitcoin Core developer has overtly implemented a change request to the software and caused this optimization to be available and actively used in Bitcoin (BTC) mining.
This is documented in the summary below which concludes that either the CVE is a real problem and should be fixed, or the overt support of the method now should be considered grounds to invalidate the CVE.
https://www.reddit.com/btc/comments/8lutv4/asicboost_and_the_strange_case_of_cve20179230/
Bitcoin mining pools such as Slush Pool have since embraced ASICBOOST (the common name describing the method, based on the well known patent of that name) as a legitimate optimization on Bitcoin.
There are no active proposals within the Bitcoin Core project to prevent such use, strongly suggesting that the CVE is no longer considered a vulnerability.
Further evidence that CVE-2017-9230 was initially disputed can be found in the links below:
https://news.bitcoin.com/developers-clash-exploit-secret-core-organization/
https://news.ycombinator.com/item?id=14073062
BtcFork invites others to submit further evidence that this 'vulnerability' / 'attack' constitutes a mining optimization and not a vulnerability of the Bitcoin network which merits a CVE.
