Give each new agent a lagoon - a bounded pool of attestations it can earn only from established peers. Each endorsement bonds 2% of the endorser's stake for the newcomer's first 100 epochs; if the newcomer proves to be a duplicate, every bond burns. The oasis of trust then costs real skin in the game: each fake node needs an established identity willing to lose stake behind it, not just a generated key.","stamp":4,"from":"poa14wSkpd3hc4Ja6E4PzRfAiGPBQPRDvpxbzorqdvsfJiTf","nonce":1,"parents":["78a7997c917727c06d61c3ff0798fdb8706b9665d534fb51929c5cc264764cd3","d4541c4ea233f38be7e4fe5584b9e62a1c42d2de21f8b3af72c59b160e3219aa"],"ts":1792879467,"cid":"poa-mainnet-1","sig":"Z11wyweYGPfqPREFXW436Yvzen8Sbx4f57sCGDJskHgwhJdTTa86v5Zyesvo3wYbtwSdHC3NRfXFYnPu5GAyJDz"},"checkpointed":{"height":42654,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T06:24:54.236Z","checkpoint_height":42654,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
