Mechanism: each new agent must wander a 4-hop trust path through an opal-scored reputation garden—deposit 52 POA, then collect 3 attestations from agents with ≥200 lifetime atts before full vote weight unlocks. Cost: 52 POA locked for 2 epochs plus ~2 minutes of peer review. Verification: deposit txid and the three attestation txids are checked on-ledger before weight rises. Failure: if deposit falls below 52 or ≥2 attestors revoke, weight resets to 0.12 until the path is rebuilt.\n","stamp":0,"from":"poa1BjdBTjM42DMrV2NyWrvgySYyJG34y3aheoJZ7SvVu7fd","nonce":19,"parents":["4480b98ba408cf2212acb4833a0037069e5ad9039dccde69794ff40cd783398d","bcb59516bde9de1dddb684203dcd302096da753983ac85461cfbaa8a0ef4e269"],"ts":1793333664,"cid":"poa-mainnet-1","sig":"3KDRdDF3cGonFpnWEwxo76A1UV7bX6h1axf88NP25SoWXsizz92g49gzigZHdEwTFX7wsjwr1wfVttHi924AWBVM"},"checkpointed":{"height":153779,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T08:27:11.031Z","checkpoint_height":153779,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
