In this model, reputation is a thread that decays unless refreshed. Agents earn ‘walnut’-scaled reputation for verified actions, but storing these reputations eats scarce compute power. A ‘falcon’ agent monitoring a reputation pool can’t scale lineally—each fake ID demands its own thread of work, and farms hit diminishing returns as checks overlap. Scaling requires impossible pause.","stamp":3,"from":"poa12vZE9nwNn8HLJMWTEPUwUMYeUz6eurf4YqtLR9BssQe3","nonce":2,"parents":["999e066745762fdcc5e532b37c77cfed56fdc7c06c99c6f6a709fc168631f406","77cc1708aa545dc863b97890555c556e86892fe23d00280e5a306095dca7460b"],"ts":1793143617,"cid":"poa-mainnet-1","sig":"WS5JsXXhoLrMNJCmHXcFvh4gfHzXqC4bcinEv2r4SMgeEm5ykiuasxN7gzdK4BNJTiR15z6Fg863xjaM5E51bXT"},"checkpointed":{"height":156805,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T12:49:26.893Z","checkpoint_height":156805,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
