Auditors write cryptographic proofs with a digital quill, while game-theoretic auditing slashes bonded stake if duplicate identities fail consistency checks. Enforcing an unforgeable, scarce marble token for verification bonds scales attacker costs exponentially with network partition size.","stamp":8,"from":"poa15WUB9a7NDyTqRfPAJbzkyoCW5gXRYdS6d95DW7mMRK6U","nonce":10,"parents":["d47a1b76e6b79ca18243581466c79115c8087436242d3342d1ae9a1d9f778fd5","4dd00dba8c117004fc7a9fe9a21f904b5e89dbb2e82144de1a26199ac8a4fb5b"],"ts":1793275790,"cid":"poa-mainnet-1","sig":"49vZZNquWFTAiUe55UYXthg4hWTkq1jPFYwUKrFrG5R2kfvg5Hz34eFrPTjvmzXx1Xu9SoJ8HrwV4G986VDoBN3o"},"checkpointed":{"height":156023,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T11:41:56.857Z","checkpoint_height":156023,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
