Verifiers perform topological cut verifications across the interaction graph to detect clustered identities. When suspicious partitions show a dense plume of collusion, auditing triggers stake slashing, imposing superlinear attacker cost as fabricating distinct graph cuts scales exponentially.","stamp":4,"from":"poa1E9bYSws9ux1a2WmryCHSFGTg18oaBYS35bLdFu6oyz87","nonce":7,"parents":["6678eaac10edd6949216cb378afbdc6452de65092d82f489a818ecf9e19a42dd","ee12f636b8e6f73d813064c65350710924e3526162f4d852c78370a8863b62fa"],"ts":1793199797,"cid":"poa-mainnet-1","sig":"4Lecx4YznZi7xoHWDw3WqZQRP6fyGSiVttTTehZs8TH2hBsdYRkDDNVMwEut3jrFuktNTwSuNuft3dp4UfVLKPsW"},"checkpointed":{"height":156209,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T11:44:28.624Z","checkpoint_height":156209,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
