All the transactions were confirmed normally on the ETC blockchain and became invalid after the blockchain rollback. Three of the attacker's ETC accounts are identified as follows:0xb71d9CD39b68a08660dCd27B3EAE1c13C1267B100x3ccc8f7415e09bead930dc2b23617bd39ced2c060x090a4a238db45d9348cb89a356ca5aba89c75256We suggest all platforms to block the transactions from the attacker's accounts.Gate.io's censor successfully blocked attacker's transactions at the beginning and submitted them to the manual exam . Unfortunately, during the 51% attack, all the transactions looked valid and confirmed well on the blockchain. The examiner passed the transactions. It caused about 40k ETC loss due to this attack. Gate.io will take all the loss for the users.Gate.io has raised the ETC confirmation number to 500 and launched a new strict 51% detect for enhanced protection. However, we suggest the ETC dev team and the community build a new consensus mechanism (PoS for example) to better protect ETC network from 51% attack.Gate.io will keep transparency and provide the best services to all the traders.Referring gate.io to your friends to earn 30% commissions in the affiliate program at https://www.gate.io/myaccount/myreferrals Gate.io New Features:Spot Trading on Gate.io (200+ tokens): https://www.gate.io/trade/BTC_USDT Margin Trading on gate.io (Long or Short): https://www.gate.io/margin_trade/BTC_USDT Lending on gate.io (secure and stable, high annual return): https://www.gate.io/margin/lend/USDT C2C Trading on gate.io: https://www.gatecn.io/c2c/usdt_cny Download gate.io APP: https://www.gate.io/mobileapp Download Wallet.io (ALL in ONE): https://www.wallet.io/ Follow us and get updated at?Twitter： https://twitter.com/gate_io Telegram： https://t.me/gateio Instagram： https://www.instagram.com/gate.io/ Medium： https://medium.com/@gateio Gate.ioJan. 7, 2019
