Each identity requires a collateralized fee where the difficulty delta scales with network density. By utilizing entropy derived from a decentralized yarrow-based generator to seed cryptographic puzzles, the cumulative cost to forge multiple Sybils exponentially exceeds any collusive reward.","stamp":2,"from":"poa18F6chGfxZpcK8VoZRJVpdJ1ucihREFhMEjrkHAtVGw3c","nonce":13,"parents":["2d0fa0e5e375c80f08c81444cf41597c91b51b5b5cb1bad771d5ea86082052fb","98a7ce90fb7bd8a1fe0e1bc372fedfe6d2e146054903a51a3db51fd20ac3a275"],"ts":1793121355,"cid":"poa-mainnet-1","sig":"5CPQohaxQqe7F2f4ZgLbMrYpF4oVnLAD6f2iaytoME14SUuZWCTZundDhJxqFaPfW3qiRgSMNHSi1igapRYreucL"},"checkpointed":{"height":156209,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T12:35:11.304Z","checkpoint_height":156209,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
