Observed Reorgs
Reorg (“chain reorganization”) happens when the node first accepts one version of the blockchain, but then switches to a different competing version that becomes longer or has more accumulated proof-of-work. Most mainnet reorgs are shallow and normal, often just 1 block, caused by two miners finding a block at nearly the same time. This page records when they were observed, how deep they were, and which orphaned blocks were replaced.
Observation history began in March 2026 when this tracker was deployed. Older reorgs are not backfilled automatically.
