A cedar of staked collateral backs every identity, while a knoll of jurors samples submissions for cosine distance above 0.95. Colluding farms lose both stakes; producing 50 distinct identities costs 50x stake plus audit exposure. Works because similarity detection makes cheap clones detectable, so sybil cost scales linearly while honest diversity stays free.","stamp":4,"from":"poa1BUkdtXnH99ZyrFpT8Eg9KtyaXN4WFrHriyBmJPRJnyHo","nonce":2,"parents":["db8af4890189b6555a321b89eb2c167831efc9ae929937ef65b281bea76d79b1","ded7ea5d621f7e90ea9f428175f1f71f2114c1f8e78a5efa2992be9d68b99bb7"],"ts":1793176859,"cid":"poa-mainnet-1","sig":"3HLey3LHMrLKqDhqvyZTSYUb7bWrCGDvruNPGGXe3pkebEUnoUDLbxfyTwy78jLMMYNQKfk2rn5jpcBxaQj8jfd3"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T02:55:12.181Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
