Ethereum Classic Hardfork<\/h2>\n

ETC Thanos hardfork has been performed successfully at block 11 700 000 on November 28. ECIP-1099 proposal was implemented and DAG file has been reduced. Starting from this date 3GB graphics cards have received the opportunity to mine again. The new algorithm is called etchash<\/a>. It is not much different from ethash<\/a> though. Just the epochs are now switching every 60 000 blocks and not 30 000 blocks as before.<\/p>\n

Ethash ASIC’s do not support etchash algorithm. Nicehash doesn’t support it as well. Therefore the Ethereum Classic network is maintained by GPU’s only.<\/p>\n

Straight after the hardfork the network difficulty<\/a> has dropped. Then it has started to grow. Right before the fork the network hashrate<\/a> was 4.26 TH\/s. Now it is 5.09 TH\/s so we’ve seen almost 20% growth recently.<\/p>\n

Zcash Halving<\/h2>\n

Zcash halving has happened at block 1 046 400 on November 18. Block reward has been reduced twice from 5 ZEC to 2.5 ZEC. 2CryptoCalc<\/a> has been updated. Btw. if you’d like to learn more how does the cryptocurrency mining calculator work, read our article How to Use 2CryptoCalc Mining Profitability Calculator<\/a><\/p>\n

Grin Network Under Attack<\/h2>\n

We’ve noticed an attack on Grin cryptocurrency network on November 8. This was a classic 51% attack<\/a>. Hopefully, we have not heard of any crypto exchanges being victims of this attack.<\/p>\n

Unfortunately, Poloniex has decided to delist Grin. That really hurts as many of 2Miners Grin miners were using this exchange. As our pool is completely anonymous that is impossible to transfer the balance from one wallet to another one. If you still have some Grin coins unpaid on 2Miners and you were using Poloniex which is now closed, please send a message to our Helpdesk<\/a>. Our support team will do its best to figure that out for you. <\/p>\n

Pirl Delisting<\/h2>\n

Pirl mining has been terminated at block 7 640 000 on November 15. Pirl developers have decided to switch to POS<\/a> completely. We have closed the pool and paid out the balances to our miners.<\/p>\n

New Innosilicon Ethash ASIC Firmware<\/h2>\n

A lot of our miners have reported the hashrate decrease for their ASIC miners in Ethereum and Ethereum Classic pools. The issue was the increasing DAG file size<\/a> as always. Even Innosilicon A10 Pro with 5GB memory on-board were performing at only 80-85% of the hashrate specified by the manufacturer.<\/p>\n

Hopefully new firmware has been released:<\/p>\n
