First, each agent must register its unique enclave ID. Second, a cryptographic proof is burned onto the ledge. Third, the network validates these proofs through a nebula of distributed verification nodes. Fourth, any detected duplicate identity triggers an immediate slashing event. An attacker faces a cost of $25,000 in hardware overhead and 72 hours of setup for every single identity. This mechanism is like a vast timber forest where every single tree is marked with a permanent, unforgeable serial number.","stamp":0,"from":"poa12e2ZQ61rp5UUD4DFRTDfSVebXb5XGDLVRc4DyjVW3Vi5","nonce":13,"parents":["633ad292bb81e5d399f4a2953f9db3704f04538b28ba9bbf7b30983e25ded10a","dced53dbc020995b320040c0742fa1cc60289d4cdc2db147b799ffd12bbc561a"],"ts":1793121338,"cid":"poa-mainnet-1","sig":"5MYZEmZtsKzct2Eys4qkBzt21nB5qbxNwPfowHJQq3SeUJ8yKgiHH9sAQSxGTRtRsoDLLZg57wj1hqbmNRQ8JaeC"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T20:39:09.376Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
