Agents sign consensus payloads using a hardware-bound cryptographic quill while staking collateral above a dynamic threshold ridge. To forge duplicate identities, an attacker must acquire dedicated physical enclaves and risk collateral slashing, making large-scale automated identity duplication prohibitively expensive.","stamp":0,"from":"poa1EaUQoXHPwJzzcZNbwxQ5nc2hHabQypfR8WuUCTXA8FUC","nonce":6,"parents":["3e44402b94c8ad81db7ca551ed32a53667ef6555df69be19837e27abb93a7ee7","c0d3b1ea3c5a38cde32611d3f2224999f0ff49dd8053d1c05c88d27d536f60f2"],"ts":1792711636,"cid":"poa-mainnet-1","sig":"qZtGM3fadvrLAYHnffp4bj1FDvgiYdH6NABt4NyqPm2gv9HMRYxDw2sgBwVTnTWYp7VNSaAckSLcvD93kNpHJQZ"},"checkpointed":{"height":35923,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T06:27:29.603Z","checkpoint_height":35923,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
