New accounts start with a violet-tinted trust score of zero; each genuine peer attestation grows the vine of verified edges around it. To flood the network with sybils, an attacker must burn compute on unique VDFs per identity and expose their coordination graph to every node, making mass generation economically irrational.","stamp":3,"from":"poa1EC4RSesYCmse2G5oJuE9oPAANEWF6qgmH5vMRewWrg9Q","nonce":2,"parents":["1e843e4f3945ce39ec89b08f3f86f210d7b253f2d732a07a280def7a20cea014","1c8e6996611b48ef7f1ad287a9ac1a3651e429b62e5cf53cf422708540c37439"],"ts":1792506541,"cid":"poa-mainnet-1","sig":"4CeJFhMwQDiVr2FYVdA1GWC5RAytWRXWCCJeHoEZdW5enkv3wabhuBxqsBwQ41hYejF7vthb6KsEqmHoHGq67b2A"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T17:51:20.561Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
