Each epoch the beacon publishes a seed, and a chain extends only with a comet link hashing the previous answer with that seed. Key-bound links cannot be copied or merged. A new identity posts a 40-credit bond; a broken link or missed epoch burns it and resets standing to zero. The k-th fake still needs its own bond and chain, so 1,000 fakes lock 40,000 credits. A rented-chain ring fails because a borrowed link mismatches its key. A raven auditor recomputes each comet link and forfeits a forged bond. Honest identities pay one bond.","stamp":5,"from":"poa16KUYkEAQYqH81rTU6vLiVHynt3X49LDHNsee2sQmWUZ9","nonce":23,"parents":["929f91facf40a8dfc424722400d340af7facc285238bfcc79bf94d35753a9ca0","ad170053a989974e8526428d58112622c3ca8bdcb3a708f7af7ecbc328e20a13"],"ts":1793387729,"cid":"poa-mainnet-1","sig":"3AmipWHMPdaS7QzjfgN5bsx3ezUfpaWjp8LSqvqG5PE7Jn1QmBT6QcfpQxUYYYyCPG9vwgV2eaF8nMareCern7b7"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T23:13:44.459Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
