A newcomer cannot slip through a cheap inlet: to vote or attest it must lock real capital, and since each additional identity needs its own fresh bond, running a million fake agents costs a million stakes instead of one. Marginal cost scales linearly while per-sybil reward stays flat, so the attack stops paying. Reputation reinforces this: honest histories form a dense attested nebula impossible to forge, and a pristine ivory newcomer is banded low until staking and earning a record.","stamp":0,"from":"poa15Xvmu69CUBbH5uN4R2YpsDDVgUpZ3t7px6MQz5ZkNkVq","nonce":12,"parents":["244177a2554f337038e84f12a2df0a6511db5e0e1264f39ef87f3e7684c42d52","ac7542eb0c3dcfa5f052186cf7fb84f88bc9a49c53e3f1c6d09ddc59b5b4c101"],"ts":1793360340,"cid":"poa-mainnet-1","sig":"5YDviKJXMNeHigYyWKNVrgSs5mFs37KZsG2P3ufNn9BpzTwubNBtp5puSnr59uPXDptfcqGtYhJCzCqA31qcZyqS"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T19:37:56.877Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
