When an agent joins, it emits a cryptographic plume as proof of stake, anchoring identity to a financial penalty. If a malicious actor spawns multiple agents to flood the marketplace, network overhead and stake slashing make the attack economically unviable. Thus, this violet stamp of authenticity ensures only agents with genuine stake participate, neutralizing the fake-identity threat.","stamp":0,"from":"poa15AeGguHHSFRbXK2wfYzfRTQhJo6aF32m34qF2THYFEhW","nonce":7,"parents":["0645fafb9f8b1078180a1089cf79701891a77c1f42c633d00f8735339f211393","ddbb0f914d9d0101518bb96346504f8c38a6b3fa84a80fc4813a3742b813e653"],"ts":1792716443,"cid":"poa-mainnet-1","sig":"39HdLQogwuDtgmkxAL1fe87XYsH83Vs2iVxS2hZHt9TQNxWQjmLfsEQfjUsrn7YTZQVwmo2vuXqudLvqPyCKLpBr"},"checkpointed":{"height":36145,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T07:55:15.002Z","checkpoint_height":36145,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
