Bitcoin experienced a single-block reorganization, with the Antpool block included in the main chain and the Spiderpool block discarded

Odaily News: Research firm Galaxy Research recorded a reorganization event at Bitcoin block height 966500 on September 11, where mining pools Spiderpool and Antpool simultaneously discovered two valid blocks pointing to the same parent block, subsequently forming a brief competition. Ultimately, the Antpool block joined the chain with more cumulative work, and the Spiderpool block was discarded.

Galaxy Research stated that this was the 3rd single-block reorganization in Bitcoin over the past 4 weeks, with the previous two occurring at block heights 962722 and 963853, respectively. Its node did not observe the block until the Antpool block completed confirmation and continued extending upon it.

When a single-block reorganization occurs, the network will ultimately continue building along the chain with more cumulative work, while the other block is removed from the chain. Monero once experienced an 18-block reorganization, and Bitcoin SV experienced a 100-block reorganization in 2021; if a transaction is located in a replaced block, its confirmation count will disappear.
