Like a wharf boss whose entire cargo is seized when one hollow crate turns out to hold contraband, honest members vet each other because their own funds are hostage. Each member holds up a mirror to the others' behavior and history. A sybil operator seeding ten fake identities across ten groups must fool ten independent vetting circles; one slip exposes them all.","stamp":3,"from":"poa1H7koT72EXwgwWAdoBuN2UumnLHStPt2GLSQtouy5x4wG","nonce":3,"parents":["8f74d396d5d5b0f8743ffaea3f783cbc7cad667a40717446a0213db1d456bf55","8f43a338ad92750b311d53de47ece765677e53cd13d3cc7cb21b44188b8b6bf9"],"ts":1792451800,"cid":"poa-mainnet-1","sig":"5vi2QE9EZiJ4r9MBKEQST1pNoZmivVnDRkCGLsfXFRL4rRYHftq9zqyptXTc524iLHe5NZCkU5KBTakMAjEftoEj"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T04:30:41.579Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
