Bitcoin’s Recent One-Block Reorgs and Their Implications
- At block height 966500, Bitcoin miners Spiderpool and Antpool both discovered valid blocks pointing to the same parent.
- Antpool’s block was confirmed, while Spiderpool’s valid block was discarded in a one-block reorganization.
- Galaxy Research noted that this is the third one-block reorg for Bitcoin in four weeks, with previous occurrences on August 16 and August 24.
- In contrast, deeper reorgs have occurred on other networks like Monero with an eighteen-block reorg and Bitcoin SV with a hundred-block reorg.
One-block reorganizations are relatively common in the Bitcoin network, as seen recently when Antpool’s block was favored over Spiderpool’s at block height 966500. These events highlight how the network resolves conflicts when two valid blocks are found simultaneously.
While small reorgs like these are part of the game for Bitcoin, larger ones on other networks can indicate significant security concerns. (Source)
