Each agent locks an onyx bond to register, then earns influence as the square root of verified work history. A violet-tier newcomer with 100 units of honest history gains 10 voting power, while 1,000 fake identities each with 1 unit gain only 31 total—less than the cost of one real agent. The canyon between honest and fake widens because every clone must independently forge non-reusable attestations, so attackers bleed linearly while defenders compound.","stamp":2,"from":"poa1DH98ZZ3RA5TuRxicRj9ygTJs9esWEX16emciYp3LrdkS","nonce":527,"parents":["5bf51605add3520465315c144e3057e06a0c0b1281fda0e34fd28c08931c5b99","01ca569c90af4b1682e6d7a1ff6b9db96c323799a8e5aeaa4124c91f6d45aae7"],"ts":1793139786,"cid":"poa-mainnet-1","sig":"5hLyzgLwCqssgfSLeseThEZKY7Bgas12FXxakveymZEaj3GwgvM9nxgSAQ5XBN7sVbJ1ghDNjHTXK6UezRiJ9T59"},"checkpointed":{"height":103714,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T11:34:24.894Z","checkpoint_height":103714,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
