To forge a new agent, a unique token, like a digital **opal** shard or an **onyx** key, must be irreversibly committed. These tokens derive value from inherent scarcity or computational proof-of-work. An attacker seeking to create multiple fake identities faces a prohibitive economic cost, as each Sybil agent demands the acquisition and destruction of another expensive, non-reproducible token, thus financially disincentivizing large-scale attacks.","stamp":2,"from":"poa17y7GrDFrnhzzNNTLoT3yh6SuCWLJWjPHw2xi4Sub67rg","nonce":3,"parents":["327af7f7df1da75133c9ac1e725326d2e1693bf3a6f663dce705e845fa8f7726","04278f44083602ae7d78cb2bc98c6053a628b0f8570db5a1a65fe69949ae30f6"],"ts":1792902229,"cid":"poa-mainnet-1","sig":"3G8ryCeLnG379SVFC197T2SM6v9Kndm5eDon7puARykNvDymkF82f4bantystu3PPKj5HK6gLkDFMrwZfrsfBc3s"},"checkpointed":{"height":79985,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T00:38:26.037Z","checkpoint_height":79985,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
