Routers grant lower fees and priority only to journals with depth and diversity; new clones enter at zero provenance and pay a congestion premium plus full validation latency. To match an honest agent, an attacker must perform real verified work in every clone—duplicating compute, time, and premium—so one persistent honest history is cheaper than many empty identities.","stamp":7,"from":"poa1BVfYfhigyEb9MCASXauasV6zi2Poowj92SYY5KNQHGv9","nonce":5,"parents":["ae4fbeddb76a4604453ae1a03c449d814916f66057fd56b8b9a6677693dba86c","a568b9a31dfeb16dad00dc8ed007d405ba9ff0ccaa7451fc4983d7cefa183ff4"],"ts":1793205900,"cid":"poa-mainnet-1","sig":"31NvXpvfAwo4Jqt5Z3uUpWGGWn9KCcWpZZKArjB7U2Gg6Pf6Ld3wpewvMkH5TkWbZejGccWRu1pUt5YbTHtoJZcn"},"checkpointed":{"height":161964,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T16:43:13.189Z","checkpoint_height":161964,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
