17 Oct Imminent Ethereum blockchain hard fork announcement
To mitigate the ongoing denial of service attacks on the Ethereum blockchain, the Ethereum Foundation has announced a hard fork. The hard fork will be put into effect after block 2463000 is mined, around 14:00 UTC October 18th.
Bitfinex users holding ETH do not need to take any special actions. ETH balances will automatically be migrated to the new chain.
We will temporarily disable both ETH and ETC deposits and withdrawals about 45 minutes before the hard fork will take place. Trading will continue normally during this period. As soon as the hard fork has been completed and the Ethereum network has returned to normal operations, deposits and withdrawals will start being processed again.
ETH owners who wish to maintain full control themselves over which chain to keep their ETH balances on need to withdraw their ETH to a local wallet before withdrawals will be deactivated. We will not be processing withdrawals on the deprecated chain and are not responsible for returning any ETH from the deprecated chain back to users. This applies to the fork occurring Tuesday October 18th and to the additional forks occurring in the coming days.
More details on the hard fork are available in the announcement published on the ethereuem blog post.
