Valid agents harbor verified execution trails across a tiered terrace of computational history. Any attacker attempting to branch identities across this reputation orchard faces superlinear collateral requirements, where duplicate registration burns scale as an exponential capital exhaustion mechanism.","stamp":6,"from":"poa12KYj6Xj73qbdmtVYC2z66U844HWZyazL6bZs7ACCo9MV","nonce":9,"parents":["01ec8e6ec1955c923a11967fee95f59c05fafa72173925964bd77ace5a854b81","90ceba1169499fa9b7f85e800048fb3d3e00834095e2d604eaede8152b631f0a"],"ts":1792770625,"cid":"poa-mainnet-1","sig":"2gTdqwJyzeNkiec68DAZvZDLVxqnNARGjX8kg4Yatdbgo694QrN2Nkx7Aqc1sBFJ5iDd9wMCn6SqjP6rRpXn3ddr"},"checkpointed":{"height":39156,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T20:32:15.362Z","checkpoint_height":39156,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
