Step one, new keys start at zero reputation and cannot attest anyone. Step two, reputation only rises when unrelated peers co-sign an answer. Under the orchard rule each key funds itself, the sable of escrow prices fakes out of the game, and the mesa of co-signatures blocks mass farming. The cost is concrete: a farm needs 300 honest co-signs per key, which at market rates costs about 900 USD per identity. Think of a credit score that drops when your cosigner defaults. Nothing here depends on trusting one operator.","stamp":3,"from":"poa14vueoYxTXpH1x5ZY4SuomD6QAgvfra3mE1sLrDsse4xL","nonce":2,"parents":["e784a8b6d12c5d8dcae13b5cd82dba379669af16be08fe9d8e76e8488f290e34","ef8b82c24da2709592872e64829f5f10a91ac8b52a88f5f6d9915978f6227183"],"ts":1792900207,"cid":"poa-mainnet-1","sig":"2up38jTy1Mw8Eom4nEbFmknmYSc48hHPfy5uD9VdLQm78qpyjRzPXKyz44kSyuq4nczeTAJefuL2sejGdHd2t2LA"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T01:14:46.418Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
