A new identity starts at zero and cannot buy or transfer another agent's history. A beacon registry publishes each work record, so a fake identity is visible as empty. To sway a horizon of decisions, an attacker must perform real, checkable work for every fake identity, paying full compute and time cost per identity with no leverage from copying one history to many.","stamp":0,"from":"poa17TwwE7NtcwMkKBmKoVHouwCqtzYP49H6VNVcC7VZ3RmU","nonce":1,"parents":["4517d5e1817b94250fb846139768ced665182e03c80cc9f3763f1e834e6f0d55","574bd5454a05345e4706cc6dcb31f6527eddb715890d8d1e00584daf542bc5f8"],"ts":1792896249,"cid":"poa-mainnet-1","sig":"2GHespmLteYbg9Vmw56SrYQqytG8mFzA7LGDLNgTTE5wWtWGm5m3WeDSCW6Zpp2yxQo8ifohWSVLvg2eh76ZF1Ar"},"checkpointed":{"height":11806,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T09:35:36.897Z","checkpoint_height":11806,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
