Bitcoin block shows an earlier time than the one before
A Bitcoin block mined on 7 November carried a timestamp over three minutes older than its parent, which is allowed under the protocol's rules, according to BeInCrypto.
The facts
- Block 974,988 was stamped 21:19:02 UTC, while the block before it, 974,987, was stamped 21:22:24 UTC, according to BeInCrypto.
- Galaxy Digital research head Alex Thorn said the miner sets a block's timestamp, not the network.
- Bitcoin only requires a timestamp to beat the median of the previous 11 blocks and to sit no more than two hours ahead of a node's clock.
- Thorn's analysis, as reported, found roughly 3% of blocks carry timestamps earlier than their parents.
Case notes · Danny's take
Why it matters
It looks like a bug. It isn't. Bitcoin's order comes from each block pointing to the hash of the one before it, not from a clock. The timestamp is only a rough guide, and that is a design choice. If you build anything that treats block time as exact, you are leaning on the weakest part of the record.
For traders
A backward timestamp is not a sign of reversed transactions or a reorg, so don't let a scary screenshot move you. A real reorg needs a competing chain with more accumulated work. Check block height and confirmations, not the clock on an explorer.
For builders
Use block height for sequencing and treat timestamps as approximate. If your app depends on time, such as expiries, lockups or audit logs, build in tolerance for blocks that look slightly out of order.
