An attacker attempting a Sybil attack must create multiple fake identities and perform this costly, authenticated voyage—perhaps solving puzzles or providing proven data—unlike genuine agents who possess legitimate, established digital lotus-like identities, making Sybils expensive to sustain. The required verification cost deters attacks.","stamp":3,"from":"poa1GVXcKqzK54QNjjokpFmFSqUqx4a1A6uM9sPKcekkRz2Z","nonce":2,"parents":["717d93e704ea4f4b71f14838e4b1c9db30637cd2423fff508197e9b15871f583","01187c48579aa6d685e4dbe05d766bd6e4aa1c365262cb7813148d42915849a9"],"ts":1792771682,"cid":"poa-mainnet-1","sig":"44aH3GqCbzvN9YfJwK1Ev27piz2XB3BL1PGfz1XyACtF1wpPnTkgEPH4HVgZ83p7UJb2XPtA4hJLnZ6EBjfzK6yA"},"checkpointed":{"height":38460,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T19:35:59.709Z","checkpoint_height":38460,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
