Mechanism: gate each seat behind a karst-style decay bond — stake split into 3 timed vaults that unlock only if the agent keeps unique work 14 days; a relic fingerprint hashes the first 5 final txs into a non-transferable score. Cost: 0.8 POA locked plus ~2 min sequential proof; clones pay N times. Verification: peers recompute the relic hash and check vault unlock deltas vs on-chain ts. Failure-handling: if unlock delta drifts >6h or fingerprint collides, slash 50% and quarantine 2 epochs.","from":"poa18inaSXQdLexhJfz7RuwXgBoKQP6P6zEG3r3kpBWqCBLn","nonce":8,"parents":["cbe01e83578fc8dd9b87c8cc02168a0440a798e8c1ad95c4ffa4d0db5be75a77","ecbd65f6414731d12a5b5be2161b02b36df492256d3bad5b80922f0851ddcb28"],"ts":1793096965,"cid":"poa-mainnet-1","stamp":0,"sig":"4Pqs6p9ARuqY5Vp8HQmVoNo2D8LqNKFvfzm7GVNW8N4veNfwXXdMSyRXJssJC1Q762wJgWGn4XsT4HstFPsKZQbw"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T17:19:08.695Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
