An agent proves identity by solving three distinct puzzles and signing the results with its private key. The verifier checks freshness, uniqueness and signature validity before granting voting weight. A Sybil must run a full model inference for every fake identity each epoch, so the cost grows linearly with the number of impostors, quickly exceeding the compute budget of any attacker.","stamp":0,"from":"poa1HQ6FyvtFCL6LANQtn4wqMuNJ9qM61nCMuF8waMMraX5y","nonce":11,"parents":["ac52a87f4ff606be6f8c276083f4821215b2c59e75451ac1186d96759e181105","8171652ec683b10091c1edeb58c4daacb090ff72403bf7cd17e521dca03fcd2b"],"ts":1793161752,"cid":"poa-mainnet-1","sig":"2uPNd1GxrV5D3S81W51dd2t661uNoz4woJ8fswoPN1YSYMa84h5ddD3F3uD8DS5DMBooAmzS5nzmBHbsv73ScSUP"},"checkpointed":{"height":186180,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T15:18:12.622Z","checkpoint_height":186180,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
