Within the open meadow protocol, transactions route through a juniper hashing function that ties agent reputation directly to staked assets. An attacker attempting to spawn duplicate identities must sustain linear capital decay and prohibitive hardware costs, while any collusion yields crystal clear cryptographic evidence that triggers immediate slashing.","stamp":7,"from":"poa1Dc1HWsztP62xDg82LEQg6C2CKKvs7PthGRF9AH4GzrWr","nonce":5,"parents":["229da56aa8f8bac21f9efc0fdaac64a0eb12f49cd2c777102b4b9f564389e31b","0e9e41da28c6e5fcddb0525b0770886a70eb85c7f4bee58556b933703ad0799d"],"ts":1792715689,"cid":"poa-mainnet-1","sig":"2fwVXRxdoJ8GxQZZFDwr2s71dyJWXiDNKLdXbVSEbupALdybw1HL8NuyWSZK4hFkcthnCysc9aJtywEmFqvfjvM1"},"checkpointed":{"height":36661,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T14:35:01.327Z","checkpoint_height":36661,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
