Excellent thread
Could you add YAC? It's a 'Limited GPU Mining' coin with on going development (launched ~ May 2013). I'm beginning to realize a lot of people don't know about this coin or it's unique features. This coin uses something called the N-factor. As this increases, so does the amount of memory required to produce a hash. Currently I have an i7-3720QM (mid grade home processor) and a Radon 7970 (upper end home graphic card) mining YAC and they both produce the same hash rate (~1.1 khash/sec). After the next N-increase (around Spring) a 7970 mining speed will be reduced to about 0.25 khash/s - making CPU more profitable. As the N-factor continues to increase it is likely that YAC become a 'CPU only coin.'
This coin had a bad reputation on it's launch. People were saying that the developers used malicious code in the original release to withdraw bitcoins from anyone's wallet who downloaded it. Someone posted rumors like this so they could mine more coins while the N-factor and difficultly was low. People were confused why they needed to 'unlock their wallet for minting' and someone used it as a stepping stone to claim 'its a virus to steal your bitcoins'. It was a cleaver scheme. No 'malicious code' was ever found and no one reported any coins missing. Feel free to review the code - I've looked at most of it as well. https://github.com/yacoin/yacoin |

Is there a MTC profitability calculator out there? Or at least a calculation / formula to estimate xxxx hash should yield xxxx MTC per day at block reward of 50 coins?

Cryptsy removes coins that have reversed transactions. After block 420,000 this issue should be resolved and they should return the coin permanently.

Thanks for the update on YAC. It looks like your thread is getting a lot of view - I know I've passed it on to several of my friends. (Read 11277 times)
Has anyone made an attempt to making a 'CPU mining profitability' calculator? There are a lot of good ones for SHA-256 and Scrypt mining, but there really isn't a way to tell which 'CPU Coin' is the most profitable. Any sites out there or anyone tinkering a a google spreadsheet?

I've rewritten the code to actually allow consecutive PoS blocks, but only give non-zero trust to the first one. Also, if my math is correct, YAC is supposed to have 144 PoS blocks/day (10 minute interval), not 720.  I didn't know PoS had a 10 minute target. I thought the 1 minute block target was for both PoW and PoS (1440 / 2 (half PoS, half PoW) = 720 blocks per day). I get up to 10 PoS blocks per day - does this mean I'm actually am getting about 7% of the PoS blocks for that day? If I'm understanding your last post correctly - does this mean (the change to the block trust) that we shouldn't see a difference in the way transactions are being minted currently? Basically seemly other then the wallet update? |

TODO - Add YAC to limited GPU category. Thanks for the add. I think it's worth mentioning YAC code was published by pocopoco, who has never been seen again (just like with Satoshi and Bitcoins). A few days later Windmaster took over the development and the 'main' development thread is here: https://bitcointalk.org/index.php?topic=206577.0Windmaster announced a few months ago that he no longer had time to continue developing the coin and has pasted the torch to Joe_Bauers and Sairon. Joe has helped established an official logo, name ( Your Alternative Curreny), and upgrade the qt-wallet. Sarion has developed a block chain, charts, raffle, and other useful information that can be found here: http://explorer.yacoin.org/. But probably most importantly, Sarion has added 'coin control' to the wallet which allows users to pick which transactions to send - to minimize the loss of coin age. I'm not an expert in these matters - I'm not sure I'd say the coin is having problems with the block chain. There are some discussions (in the on going development thread I posted above) about upgrading the code to have PoS produce 'chain trust.' With a block target of one minute (and PoS blocks happening even quicker) sometime two PoS blocks are created at the same time - creating an orphan PoS block. I believe this is what the development team is looking to correct. I mine CPU and GPU (while GPU is still an option - at least until the next N-increase) this coin and trade it on bter and cryptsy. The coin has been around for a while and has a strong community (which includes the forums at yacointalk.com). I personally feel although this coin best fits under 'limited GPU' instead of 'high risk.' Out of all of the coins listed here - (AFAIK) YAC is the oldest has has had the most development work done. Please move YAC to limited GPU, update the name (Your Alternative Currency), update the development link (listed above), and update the description - the 'block chain issues' have been resolved. See the below thread. https://bitcointalk.org/index.php?topic=423519.msg4608851#msg4608851Thanks! |

I have downloaded already. Tried with CPUminer and also with YACminer (whjich is actually a modified cgminer for YAC) but no soccess at all  Could You please one of You who are mining give me a proper command line  With my settings is always error message like "no reply by emty server" or only rejected with boooos Thank You in advance. You can hit me by PM as well. For GPU I use the following command line: start yacminer.exe --scrypt -o http://yac.coinmine.pl:9088 -u *user* -p *pass* -w 128 --lookup-gap 2 -I 8 --thread-concurrency 8192 -g 2 --gpu-engine 1200 --gpu-memclock 900 --gpu-powertune 20 For CPU I'm use: start minerd-corei7.exe -a scrypt-jane -t 4 -s 2 -o stratum+tcp://yac.coinmine.pl:9088 -u *user* -p *pass* Which pool are you using? Maybe try yac.coinmine.pl? I haven't had any problems with it. |

Our block target for YAC is one minute. This would imply that there would be a maximum of 720 POS blocks per day. As YAC continues to grow, this may not offer many opportunities for people to mint their transactions. Therefore, is it possible to....
1) Mint more than one transaction at once/per block? (i.e. Five transactions of 10 YAC w/ one coin-year each, in an unlocked wallet would mint in the same block, and be returned a single transaction (50.50 YAC)
2) Increase/remove the 'coin-age' cap? (I believe transactions stop gaining 'coin-age' after 90 days)
This would help reduce the number of PoS blocks generated by a single user and ensure they wouldn't loose any coin-age / 'interest' on their unspent transactions. PoS target interval is 10 minutes. Setting it too low, however, would somewhat reduce the security of the network (lowering the active stake volume 10 times faster and we don't yet have enough PoS minters to negate this effect). Problem with #1 is that it would kinda defeat the PoS minting pseudonymity if you would merge multiple addresses into one PoS block. #2 would IMO also be bad as it would allow someone to absolutely dominate PoS minting for quite some time (as his coins would have a huge chance to be selected for PoS). You too late, you lose. 90 days is a plenty of time.So we still think transactions will have a reasonable chance of being minted in 90 days? If so - that voids all of my concerns above. I thought if the update prevented two POS blocks from being being consecutive, this would reduce the number of POS blocks to 720 per day. With less POS blocks, I was concerned that our transactions may sit for months (or years) before having a chance of being minted. Transactions would quickly hit their coin-age cap (90 days) and only a static few (~720) transactions would be minted each day. I have this issue with PPC - I have several transactions that haven't been minted in over a year and they are no longer gaining coin-age. They are all reasonably sized and have hundreds of coin-years in age. Never the less, they aren't minting - making them less appealing to hang on to (not to mention the full year I've wasted holding on to them). I just wanted to make sure we didn't introduce a bottleneck like this to YAC. |

Is anyone out there who are succesfully mine YACOIN with cgminer Is it possible to mine it with GPU or only with CPU ? I cant get cpuminer nor cgminer to work. Always get error message "no reply by empty server" or if hashes, then all package rejected, 0 accepted. Help or advice (proper settings) needed !!! Thank You in advance for ur replies... YAC requires a special mining software because of the n-factor and the scrypt-jane algorithm. It can be download from here: http://yacointalk.com/forum/index.php/topic,350.0.html Right now (IMOP), it is more profitable to CPU mine YAC and GPU mine something else. I'm been trading my GPU mined coins for YAC on cryptsy and bter. Send a pull request for all of your recent changes when you have a moment. Block 400000 (!!!) is coming up soon so if anyone else wants to provide feedback or alternate solutions do it soon. If not, I'm going to merge sairon's changes - probably by the end of the weekend.
I'm in favor of sairon's fix at block 400,000. I think it will fix the immediate issue and will be easy for the community to implement. But I do think we should consider the following... Our block target for YAC is one minute. This would imply that there would be a maximum of 720 POS blocks per day. As YAC continues to grow, this may not offer many opportunities for people to mint their transactions. Therefore, is it possible to....

Great communit and on going development. What other coin had a phone app within a days of launch? DM3Hq6VoYmfjszmiaVM1mFGcMoWZBh2Vib |

I bought coins through Coinbase w/o Dec 13th as well. The money was withdrawn from my checking and I also received the notification. When I looked the coins weren't there... I reported it and they credited my account.
It sounds like your transaction might have been effected by the same 'glitch' that my transaction encurred. Hopefully you will receive your coins soon!

Could be an exchange, maybe.
That was my first thought too - It might be bter or crypsty. If it is, we should see coins coming and going from the wallet as well. |

Guys, have you seen that address YPGNWtN4gHFDQUvU9eC8Xzss5JCyT1ozmv with huge bunch of YACs?
It has more than 25% of ALL YAC!
Can it be the Scam or is it normal?
It does seem a bit odd... Balance: 3,734,100 YACTransactions in: 6,781Received: 3,763,601 YAC Transactions out: 23 Sent: 29,501 YAC First Transaction: 2014-01-03 02:22:02Any of our big hoarders decide to move all of their coins to a single address? Most of the transactions are for the same amount; 3,000 5,000 or 10,000 YAC. That makes me (hope) that someone is just moving all of their coins to a single address for future minting. It looks like the wallet address was only created ~96 hours ago. |

I am getting 1 coin for every 12 hours and it reads as mined. I have 121 mil in my account.
Does it make any sense? I have 10.0.0 version.
Regular mining generates 1 coin per block found and is basically pointless now. Is this true even after the updates on the 8th? Has this coin (basically) become POS only? |
