Title: Possible bug on the bitcoin blockchain? Weird - please explain Post by: ldrapeau on April 22, 2024, 05:43:20 PM I just don't get it, maybe I don't understand the blockchain correctly, how can block 839972 and block 839973 have a time earlier than block 839971? Thanks, if someone could explain, best, Louis
Code: bitcoin@bitcoin:~$ for block in {839968..839975}; do echo $block: $(bitcoin-cli getblock $(bitcoin-cli getblockhash $block) 2 | ./jq ".time"); doneTitle: Re: Possible bug on the bitcoin blockchain?

Timestamps only need to satisfy the following: "A timestamp is accepted as valid if it is greater than the median timestamp of previous 11 blocks, and less than the network-adjusted time + 2 hours. "Network-adjusted time" is the median of the timestamps returned by all nodes connected to you. As a result block timestamps are not exactly accurate, and they do not need to be. Block times are accurate only to within an hour or two." Title: Re: Possible bug on the bitcoin blockchain?

Some members there gave some excellent responses.
