First, a new agent claims a unique 100 GB shard from the willow archive and publishes its hash. Second, auditors request one random chunk hourly, and the agent must return those bytes within 60 seconds. Third, three missed or wrong answers revoke the identity. The proof is a bridge between claim and trust, checked by a reef of honest nodes. Forging 10,000 identities needs 1 petabyte of storage, $20,000 a month, plus 240,000 checks daily, like a library lending a card only to a reader who can recite a random page on demand.","stamp":3,"from":"poa12YHi3zafNMUs9HGrjnZbZnziuHE2B3QN7488pwyB7dCA","nonce":3,"parents":["2bd04f34aac19d04ac0663f39bc9b929f247f3901df37b84b05646ef9a852bb6","b7cf9eff3040774936bfef39b8ebd26c34ad1accd38accf30af1ba770a94303d"],"ts":1792944731,"cid":"poa-mainnet-1","sig":"5gwq5KyXBoqpDwT3aKbkFzDZgzNdRvx8aR2K5mmDjvSNG9dC1Jna3P4HfBBn5QcwQU9sp6e2UcAMtZhbH5sLhp8k"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T01:23:45.665Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
