Blackcoin has been running a 'fixed' POS block reward of 1.5 coins for a while. The original protocol used a 1% inflation (new coins) generated each year. I made a post about this back in 2015; regarding how having a fixed block reward is notably different from a true 1% annual increase to the total number of coins.
https://bitcointalk.org/index.php?topic=469640.msg12860963#msg12860963
Has there been consideration to make the block-reward dynamic based on the total supply of coins? |

YACoin Resurrection Hard Fork – Heliopolis
...
-Unique algorithm. Sticking to its roots, YAC will maintain the inventive scrypt-chacha (aka scrypt-jane). NFactor will be set at 21 to be ASIC resistance but also mineable for many CPUs and GPUs.
...
I was hoping to better understand this. Currently (pre hard-fork) the N-factor was set to be increase on a fixed schedule. After the hard-fork I believe it will be "set" to 21. What are the plans to increase the N-factor over time? As technology improves so will the mining capabilities. Litecoin for example - was "GPU proof" and shortly after home graphic cards became powerful enough to mine. Following that the "scrypt" algorithm became ASIC territory. I'm sure we don't want something similar to occur to YAC down the road. And to increase the N-factor when 'ASICs seem to be getting close' seems arbitrary. Is there something in the protocol to handle N-factor increases? Or can it be included? |

The Yacoin webpage should be updated. https://www.yacoin.org/Not sure who owns the site - but it is still pointing to wallet version 0.4.9. Also the faucet link is broken. |

I'm wondering how it was decided to convert YAC to POW only. I don't recall seeing a discussion here, in GitHub, or miners voting with their hashrate. YACoin Resurrection Hard Fork – HeliopolisYACoin is getting an upgrade (finally)! At block height 1,890,000, a hardfork will occur. Here is a list of main features of the upgraded chain:-PoW ONLY – No more Proof of Stake. Proof of Work is the innovation of Bitcoin. -2% annualized supply inflation max. Fees are destroyed, which can cause supply deflation with increased economic activity. The block reward is calculated off of the total money supply. First PoW coin to do so. -Unique algorithm. Sticking to its roots, YAC will maintain the inventive scrypt-chacha (aka scrypt-jane). NFactor will be set at 21 to be ASIC resistance but also mineable for many CPUs and GPUs. -Intelligent Block Size Increase. Block size will increase over time at no more than 2%--dependent on the total money supply. -Set epoch lengths. At 21,000 blocks for each epoch, the ‘compounding bad luck’ problem faced by the mining ecosystem is addressed. The system incentivizes more decentralization, smaller miners/pools. -Timelock and atomic swap/loans capabilities. Upgrade includes many bug fixes (incl. txid malleability bug, UTC timestamp bug) as well as other features and more to come.

I am having an issue with "xpmclient-cuda-10.3-win64". To my understanding this is the windows version of 10.3. However, I am getting several errors all with similar path ways that appear to be in a linux format. Each time I start the miner, it will run for around 1 to 3 minutes and then it will stop and log one of these errors in the log. error: 700
failed with error CUDA_ERROR_ILLEGAL_ADDRESS at /home/user/build/xpmclient/src/xpm/cuda/xpmclient.cpp:656
error: 715
failed with error CUDA_ERROR_ILLEGAL_INSTRUCTION at /home/user/build/xpmclient/src/xpm/cuda/xpmclient.cpp:656
error: 716
failed with error CUDA_ERROR_MISALIGNED_ADDRESS at /home/user/build/xpmclient/src/xpm/cuda/xpmclient.cpp:656
I've searched several of the files but I didn't see a way to update this path. Clearly (using Windows) this is not the location of CUDA. I was wondering if anyone else had this issue or if I was over looking an obvious fix? |

It doesn't look like yac.yacoin.club is up and running any more. Are there any current mining pools? If not, can we set one up?

Lots of good news coming up. People are working hard in the background.
When will be new versoin of wallet? Hopefully in the next few months. So.... I'm beginning to lose faith. We have been promised a new wallet for over a year (it honestly might be two). While I have my cpu farm running strong and we all keep waiting and praying for the developers to give us an update; there are several people who are just pumpin and dumpin our coin. I haven't remained loyal all of this time just because I'm stubborn and don't want to accept a loss. It happens. I get it. But people - do you understand the protocol of this? It is exceptional. It is something worth holding on to and continuing to mine. However.... YAC came out in 2013. And unfortunately we have seen little development of success. One of the biggest problems are people are trying to work independently. Tbh, there are probably even more miners than I realize, but... when we don't have promised updates, and the websites are down, and the forums can't be accessed, and the blockchains aren't viable, and we can't even get on an exchange.... To someone new? They aren't even going to learn the fundamentals of the coin. btw? Hows that white paper going for the public in 2014 and it will be posted soon. Guys, are you listening. Yac, has a very strong, fundamental idea and way of countering ASICs and providing an even distribution. The things most people hate about bitcoin. I don't understand why this is still under the radar. PS - I syned my wallet today. From my mining, I have a total of about 3700 yac. I'm not some big time investor who is trying to get paid like a lot of people on these forums. this is one of the few protocols I've seen that is truely unique - and yet, we just accept that it didn't catch on. guys, I'll say it again. This is our coin. Our project. What are we doing about it? Edit: lets not forget less than 100 posts this year.... and I forum I still can't access even after I've emailed the webkeeper. And the faucet? Number 1, 2 or 3? ha, haha, hahaha - I don't want to even think about it. We look so stupid right now. |

This is for testing. We are hoping to release 0.4.5 "soon" as in, when we're done testing  In the meantime, everyone should be using 0.4.4 This is good news! Any chance 0.4.5 will have the cpu miner integrated? And hopefully resolving this? (see below) As it stands now, I can't cpu mine on any Windows 10 machine. On a side note - is anyone using Windows 10 to mine? I was trying to set up a miner yesterday using minerd-yacoin_stratum_x86_2_4_0 & minerd-x86-corei7.exe yesterday afternoon but it just crashes. It worked fine on Windows 7 just a few hours before the upgrade.
Also, this miner still shows as a Trojan on AVG and windows defender. Anytime I want to mine with it, I always have to add it to the exception list. I personally know a few miners that this has scared off from mining YAC. Does anyone know what is causing this miner to be flagged? I mean cgminer, sgminer, bfgminer, etc. all work fine and are comparable AFAIK; but they are not flagged as 'a virus'.

Has anyone requested YAC to be added to Poloniex? https://poloniex.com/coinRequestMaybe someone more knowledgeable than I am can submit a request and adequately complete: If this coin has any significant innovations over other coins, please elaborate on them here. |

Surely a working exchange with low exchange is better than one folks don't trust?
I have to agree with this. It may be impossible for BTER to rebuild their trust with the community. With the number of people reporting scams and ripoffs, I'm supersized they are still in operation. Either way a new exchange would probably be the best. Hopefully Alcurex adds it soon. It looks like YAC is next on their list to add; based on the donations. On a side note - is anyone using Windows 10 to mine? I was trying to set up a miner yesterday using minerd-yacoin_stratum_x86_2_4_0 & minerd-x86-corei7.exe yesterday afternoon but it just crashes. It worked fine on Windows 7 just a few hours before the upgrade. Also, this miner still shows as a Trojan on AVG and windows defender.

Does anyone know what is causing this miner to be flagged? I mean cgminer, sgminer, bfgminer, etc. all work fine and are comparable AFAIK; but they are not flagged as 'a virus'. Edit: Isn't v 0.4.5 supposed to have an integrated miner in the wallet? |

Please, help.
PoS works in wallet 0.4.4 or know???
And how many coins and days needs to PoS?
I've been using v 0.4.4 for quite a while, and POS has been working fine. Transactions must be at least 30 days old before staking. I'd recommend staying away from Bter until they address this problem. I'll share any updates I have.
More and more it start look like fraud. Lets hope we get some other exchange as soon as possible. I too have had issues with bter and would perfer to stay away from it. It would be really nice if YAC was on shapeshift or another reliable exchange. |

What is interesting right now is that the reward per block has reached the max that is set in the code (100 YAC per block). If the difficulty drops 100 fold, the block rewards will not change, unlike what has occurred up to this point at each NFactor change.
As an update; according to the pool and wallet statistics it appears the block reward has fallen to 95 coins per block (and is still dropping). Looks like there is some serious mining power being added to cause this increase in block difficultly! |

I'm a little confused, is blackcoin still 1% interest per year or is it 1.5 coins per stake?
At a block target of 64 seconds, with 86,400 seconds in a day; we can expect an average of 1,350 blocks per day, generating approximately 2,025 new coins per day. At 365 days a year this yields a stable 739,125 coins generated per year, approximately 0.9855% of the initial distribution.
I understand this is approximately 1%, but as blackcoin grows in age, this annual inflation will continue to shrink percentage wise. I have also read the white paper on POS 2.0 and understand the cause of the change to POS, but I don't understand why this reward is not dynamic.
Are there any plans on correcting the POS block reward to yield a true 1% per year? Perhaps since there are approximately 492,750 blocks per year, the POS block reward should be 1/49,275,000 the total coins in circulation; which is a statistic that is already available to every wallet and node. This seems like it would be a quick fix and then we could secure the integrity of truly supporting a 1% inflation per year. (Note: a more precise method would be to also take into account the compounding of each block to calculate a true 1% growth per year, which would result in a reward a block reward little lower than 1/49,275,000 of the total coins per block).
BLK has static 1.5 BLK reward nowadays. As it was possible to switch to this system on the run, it's not going to be problem to adjust reward size later, if seen wise. Dynamic POS reward system has a flaw, you can stake once a year and you still don't lose any stakes. You build up massive weight during that year and it's more probable to stake as you should have huge wallet weight compared to others. If everyone would stake once a year our network wouldn't be that safe. I'm not completely sure about this, but I assume that, if it would be dynamic, there would be need for new parameter counting block online time. Otherwise it would count coinage and same once a year stakers get same rewards without helping network at all. And counting block online time might not be wisest option. The more a coin switches its protocol, the less (long term) trust the community tends to have. I understand the flaw in 'POS protocol' and the urgency to change the POS block rewards to reward holders who run their wallets more frequently; and therefore securing the network. However, (with my limited knowledge of code) looking at the source code, it does not appear that this reward is dynamic, but rather fixed at 1.5 BLK per block. With the current circulation of 75,063,099 BLK at the time of writing this post, and using the approximate 739,125 generated per year in the above post, we can see the following: November 2, 2016 - Expected Yearly POS Reward: 739,125 BLK, Total BLK: 75,802,224, Yearly Inflation:0.97%
November 2, 2017 - Expected Yearly POS Reward: 739,125 BLK, Total BLK: 76,541,349, Yearly Inflation:0.96%
November 2, 2018 - Expected Yearly POS Reward: 739,125 BLK, Total BLK: 77,280,474, Yearly Inflation:0.95%
November 2, 2019 - Expected Yearly POS Reward: 739,125 BLK, Total BLK: 78,019,599, Yearly Inflation:0.94%
November 2, 2020 - Expected Yearly POS Reward: 739,125 BLK, Total BLK: 78,758,724, Yearly Inflation:0.93%
November 2, 2030 - Expected Yearly POS Reward: 739,125 BLK, Total BLK: 86,149,974, Yearly Inflation:0.85%
November 2, 2040 - Expected Yearly POS Reward: 739,125 BLK, Total BLK: 93,541,224, Yearly Inflation:0.79%
November 2, 2050 - Expected Yearly POS Reward: 739,125 BLK, Total BLK: 100,932,474, Yearly Inflation:0.73%
November 2, 2100 - Expected Yearly POS Reward: 739,125 BLK, Total BLK: 137,888,724, Yearly Inflation:0.53%
November 2, 2200 - Expected Yearly POS Reward: 739,125 BLK, Total BLK: 211,801,224, Yearly Inflation:0.34%
November 2, 2300 - Expected Yearly POS Reward: 739,125 BLK, Total BLK: 285,713,724, Yearly Inflation:0.25%As we can see, the yearly growth from POS by 2020 is already approximately 0.93% and it continues to compound (ie as t -> ∞, POS -> 0%). Blackcoin has something other 'copy coins' don't; its the original pure POS cryptocoin. I find this current protocol an unacceptable deviation from the original source code. Again, I am not a professional programmer, but I don't see the need for a 'new parameter counting block time.' Since the blocks already have a target of 64 seconds per block, the diffcultly readjusts according; therefore, the dynamic reward could possibly be calculated from the total number of coins. |

Anyone else have coins stuck on http://yac.erlog.pt/ as well? I haven't received my payout in months and I emailed the pool owner a few time (no reply). Who runs this pool anyway? |

You guys are throwing a round a lot of good stuff - most of which is over my head. I'm glad to see that both of you are activity working on fixing the outstanding issues. I hope see them resolved soon!

I thought the orphaned issue was 'fixed' and the 'malicious miner' had stopped. So are you saying that even if I do get solo mining working there is a very good chance that the computing power I dedicated to mining will be on a 'split' blockchain?
Yep, exactly! Even all PoS blocks that your wallet has found will be orphaned. You can check it later by yourself. We are waiting for the fixes that senj has proposed and for consolidating the hashpower. I have running pool in standby mode with a little hashpower just for monitoring situation. But everybody welcome to mine, of course.. So we can't mine or mint or send transactions right now.... How long until the 'quick fix' is applied? Is there an ETA or timeline for this to be implemented? Until YAC can be mined by the community again, and not one miner, the coin is dead... |
