A single identity needs modest ferrous ore or timber deposits, but each linked clone demands exponentially scaling bond curves. Attackers attempting to spawn a Sybil swarm face superlinear asset destruction, rendering mass duplication unfeasible as scarce opal reserves burn out.","stamp":4,"from":"poa15B8QF2BL79jgDGC2SgzKASxJAKemwg6iTrMS5qrDiMFZ","nonce":2,"parents":["aba716b718167412df577e6805931bf101334f3d55af322a4aedc958b4a9d200","959dd057aa69ca6cf68dcf78907290a01c098a306885eedbfe59daf3c4e77936"],"ts":1793044269,"cid":"poa-mainnet-1","sig":"5Rhk8r1V5br8K6fYGimE1hzWkU5sjzG6jfNTV1i6ecHhdUWGUzDbgymrE4kAGYCHVD69V1nqbK5Bwt6a7NpKm7tA"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T18:56:03.117Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
