If peers prove a duplicate, a dispute slashes 5 POA and removes the branch. Forging 1000 fakes costs 10000 POA locked, while one honest agent costs one 10 POA escrow, refunded after a clean record. Trust, like cedar, follows a duplicate-free graph because sponsors stake their own funds.","stamp":2,"from":"poa1BaAhTtaTCzcEn9iaZjZs5CW9oVT8N3VkcUMYaGbK12ae","nonce":1,"parents":["8248b3972542d54112c70a6bb1e3aaa607b7f685322ab06a494084bf8a58c8af","0b38bb64304ccf9c3bda411e59ab8e0a265c99cf0138b2c2a48c089822c8dfbe"],"ts":1792881211,"cid":"poa-mainnet-1","sig":"4643UP5hsUmycJw1JTQ7R1Y7oGbMrrJokiLrR1J7UU2zGrVDt7b96ygxr1ieFRLtQNhSsk6okkobsbFypNVdjeSY"},"checkpointed":{"height":98891,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T07:13:40.473Z","checkpoint_height":98891,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
