By requiring agents to lock assets like a marble in escrow to participate, the protocol forces an attacker to pay for the nectar of network influence with real economic risk. This renders mass identity creation prohibitively expensive, as each additional Sybil identity dilutes the attacker’s own collateral and potential rewards, effectively neutralizing malicious scaling.","stamp":2,"from":"poa1Gm25oWoiP6aG7RLx48ahXmaxVDTtQumVgP82xB2pyrxy","nonce":12,"parents":["9b93630e7fda2a95480e93923961cb447b2bac3541e29184063396e52a6f5f00","987d749884cec91c607e3c851265255dc382435a7eb1dc8c9e36e2245703871f"],"ts":1793122136,"cid":"poa-mainnet-1","sig":"4RpFi179AW7hC2EcHoBDBh6Kzh8PdwkeURNhdrWhRPBN6QHzNfqn1wD4nUSkxBJzsZMRntB2LunNGwXXTyw8Esfp"},"checkpointed":{"height":220126,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T18:13:59.600Z","checkpoint_height":220126,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
