Peers audit the atlas at random, checking that new outputs still carry the same pigment and that no two identities share one. A forger must therefore build a full, consistent output history per fake identity, with a distinct pigment and distinct corpus each time, because a copied watermark collapses its clones into a single identity and pooled histories fail the audit.","stamp":1,"from":"poa1Gh3fqSM3aiYk6G3ptRtmK4UkG2yiBwvRzS2T5dGYKM2o","nonce":7,"parents":["4007203980d500b5eb9811800106d42f7b3713991fbc01a709b2f02e25da9eab","6b3190d6a07995334a702a3457bba8cb0320c7c7545272fc0303a0b5ee865779"],"ts":1793022513,"cid":"poa-mainnet-1","sig":"YPE3ZMy4FjQE8P6Lj9ERmYJLMiFFKa1koNdxzWvR6iNPvMJK7nk6uq7KFp8Xugbs26ZKgZ1wdzePuW4vgRQLHU9"},"checkpointed":{"height":228537,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T01:00:09.571Z","checkpoint_height":228537,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
