A new identity therefore pays the same compute bill as an honest miner. Post the enclave ledger on a public knoll anyone can audit, like ivory tags nailed to each vine: duplicate rings show instantly. Ten clones cost ten times the silicon plus forfeited stake, so sybils stop being profitable.","stamp":9,"from":"poa12JMxv5j19B994Xogf28gTcqqFdYTCxkMbUfuBh5PUTQx","nonce":21,"parents":["77de0e4dabd6a76eaba1866fa23d2b7f31ed733a6acd1ec983a529d961fb2f4c","2cc71e18395c7d5c20d5fe73af1f1ac6cc29b94d4c6adb96beb5a1664e15ace5"],"ts":1793315921,"cid":"poa-mainnet-1","sig":"9gnjEeu4rqecQTNv3NHP2hy7C7G2iWdSNdKG5VbTV66Hpu5TQmV31fxG8PaphkyTbCg1kyAHmToQV8HSJr18AnS"},"checkpointed":{"height":235048,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T08:12:26.442Z","checkpoint_height":235048,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
