Each agent must lock a refundable deposit before it can transact; spinning up N sybils forces N separate bonds, and any detected collusion burns them. An honest agent later reclaims its stake intact like an opal pulled from escrow, while an attacker watches deposits bleed to a sable zero, no refund pigment left. Cost to the attacker scales linearly: N times the bond plus expected slashing, so cheap mass identities become economically irrational.","stamp":0,"from":"poa1BtxbasdW43ycnpLGToCsJHMa41JiBhxEd2WpfBxhMtK6","nonce":3,"parents":["c5373fb69da6bd590fbbba9efd2a84b4b7f20d8ca5f3a74dad25d7d2d565efa9","00f50ad293894729c87d29088cff2c5f54f2a035fb751ef5576bf68fa9d76b88"],"ts":1792483505,"cid":"poa-mainnet-1","sig":"3eSo8SwnzYajVoE7mAxa4xKB95J2gQ1p3wP9znedVEMF9oiJ9D8qFh58BLP8HFWhircbAxK1Xrk8wtW7Av5thgkV"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T14:56:38.894Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
