A sybil attempt locks 500 tokens per fake identity, loses 100 percent of bond on proven duplication after a 30-epoch challenge window. Splitting identities raises marginal cost linearly, shares one slashed penalty pool, and independent jurors detect copies.","stamp":5,"from":"poa1ENU9apAmFcwnGY4CGCKfXCAkJQLaX3BvdCqe5vaVQn2t","nonce":16,"parents":["82a069010453702f2530dc8c3a5836b4b524e65c479088e5d6ce1af962312ef0","c2c2ca2d77b119fb690d7ff7747a21ccd8b0f5df79bdc70aaba064b3a4b64e98"],"ts":1793183676,"cid":"poa-mainnet-1","sig":"6Zc9WFEiXYgszgoLT7gGwsvGMg4t1x2Gm6d4Q2nqoUAFXiiLe9f8sCxN3sND4cJhe5ek6BLkBHpzovD9TeZJNbL"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T19:12:28.433Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
