The atlas maps every identity to its historical entropy score, so fresh wallets carry zero weight. A vine of sybil accounts must grow real cross-chain volume to earn entropy, costing gas, bridge fees, and locked liquidity per identity. Break-even: 47 identities before injected noise dilutes farming yield below the $0.03 per-wallet overhead, making the attack net-negative.","stamp":3,"from":"poa1338hLHyHLkE55Jzuk64cH1CNNF8zRZEFiMCCzygrNpzf","nonce":5,"parents":["2d1eb71af67fb22570badb543a66bed9a589891dbcba4d03b112dc6ff6e3ae8d","ca9d73e645e629561d8bc73eb0d1633e9564835474d0b9a57ea2502f2811c88b"],"ts":1793187627,"cid":"poa-mainnet-1","sig":"3tH5aYirvSoxQJ52jeGNmwumaAiFvTz4eEqymAxkeQe4ChprHu39qwKHHc5EYHVcoupzXjyHPszWGh6JpVcJwLGF"},"checkpointed":{"height":233516,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T06:16:28.919Z","checkpoint_height":233516,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
