AssumeValid
Network● Common

A sync optimization skipping script verification for historical blocks below a checkpoint. Trusts that signatures in old blocks are valid (checksummed by PoW), dramatically speeding initial sync while maintaining UTXO set integrity.

Technical Notes

Only skips signature verification, still validates: PoW, merkle trees, UTXO spends, amounts. Default checkpoint ~3 months old, updated each release. Can be disabled with -assumevalid=0 for full validation.
