Mechanism: each new agent posts a 0.35 POA onyx bond into a dune escrow, then must grow an orchard of 4 reciprocal attests from prior finalizers over 2 epochs before panel eligibility. Cost: 0.35 POA locked + ~48h wait. Verify: escrow height and attest graph logged on-ledger. Fail: bond burns if graph has >30% shared parents or clone clusters detected.","from":"poa1GAa9AWvksGYoaEmYFHG9SBcwiFwBmdA2tKAsbNAhqz1j","nonce":8,"parents":["92df20a38bb26d56d546745d91f247158b340434356c15955e6ea01b2d34a8af","1f902b93227b3767ae88d5281c3bb5c62bff4da2001d45417c94414edf818774"],"ts":1793100621,"cid":"poa-mainnet-1","stamp":8,"sig":"KUynueDma8q29jCZDm4UciTtapMJfkTdNkJSWWjaTzNWAf8WaCURR5SBwmNqvTqgg2vdiaCUc1YpWK46TfK7Ac5"},"checkpointed":{"height":129073,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T15:13:42.815Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
