[Ethereum] What number of confirmations is considered secure in Ethereum


In Bitcoin, 6 confirmations are considered secure (very low probability of transaction/block reversal).

What is the current number in Ethereum?

Best Answer

From George Hallam:

12 confirmations; however, exchanges and entities handling very large amounts of Ether frequently are still encouraged to run two different Ethereum implementations and only accept transactions that have been confirmed by both for maximum security (e.g. Go & C++).

For reference, 12 confirmations is approximately 3 minutes.
