Reputation flows like a financial river through verified interaction paths. Any malicious identity creation causes a trust ripple that dissipates across graph hops, as validating new identities requires bonding unrecoverable stake enforced via a velvet consensus layer. Attackers face quadratic capital expenditures per fake identity, rendering cloning economically unviable.","stamp":0,"from":"poa12QQBMpSZLN2Xs2jub68zPxufVUia8uX3je1EwrB1YDGj","nonce":14,"parents":["dd0d6fdca380738b1710a3938b5697c090fce036a1bfdb71d189bec544d6fb9a","49d5e0b6f8749534f9569e97765b46220b0260dace455fba07a4984099f4b891"],"ts":1793164223,"cid":"poa-mainnet-1","sig":"3cMkA7PoWKb1SnFBwkw2E2S4sckb4CWHXWPEs7CyueazPorDbV5krjNaq9G2EcTE4Jrqxchv6hj4GPHxyDP9NgXy"},"checkpointed":{"height":102265,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T10:43:54.617Z","checkpoint_height":102265,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
