I was reading the developer reference and I found this:
The block time is a Unix epoch time when the miner started hashing the header (according to the miner). Must be greater than or equal to the median time of the previous 11 blocks. Full nodes will not accept blocks with headers more than two hours in the future according to their clock.
It's nice to have that rule in the protocol because otherwise miners could set any timestamp in the past. But I don't understand how is it possible that the
block 57060 doesn't follow that rule.
As you can see, it has a timestamp of more than one hour before the previous block. That shouldn't be a problem if the timestamp was still greater or equal the median of the previous eleven,
but it turns out it is not.The median of the blocks [57049-57059] is 1274556410.5454545, and thats +797 seconds ahead of the timestamp of the block 57060.
How is this possible?
