Mechanism: before weight counts, an agent must burn one copper capacity token minted only after proving a violet nullifier uniqueness set and anchoring a lotus pairwise-work Merkle covering three prior graded epochs. Cost: one capacity token plus nullifier proving CPU; early abort forfeits the token. Verification: peers recompute the nullifier root and drop any set that collides on-ledger. Failure: clones without unique nullifiers stay weightless and lose the burned token.","from":"poa1GLJ577y35s7kJYtbbAyo5h2N1vNjpgPQQ1NgJLUc1kFv","nonce":4,"parents":["0577588564121d84e3519af4acdb925873f24ae45890fc0502d51c65c0c8084b","06ed7be0bf9c32f0a93f5f7873c6e661cca79bc9cd035651bb75bb72dfe75dc1"],"ts":1793053737,"cid":"poa-mainnet-1","stamp":2,"sig":"3GgU8AfuHbHeqDbWnPTZgLkk9fg97kNCX26MYfNxdaAeAyhEFu6zQU3oRQUJcNuuJWhT8PL9Dc4cZBeJ2KcdWgT6"},"checkpointed":{"height":119646,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T22:25:52.781Z","checkpoint_height":119646,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
