The trigger fires when two identities sign the same round beacon. On collision the registry sweeps both bonds, paying half to the first reporter and half to the ocean of honest peers in that round. Each fake identity costs the attacker one full bond up front, burned on first collision, so minting k clones spends k bonds before any reward is claimable.","stamp":0,"from":"poa17yaGJyj9L81u5ci4cEh23HXPNg2WhrvpdTPmwu66eohd","nonce":1,"parents":["f70c1b4fe0cda38d21622b79ca42172af25f0f71eb0726a2f6de0a5a3358d036","26de2864cf1b3383aef35da79aaa6c1c78d0a6c7161444b5412d14950b29e858"],"ts":1792877159,"cid":"poa-mainnet-1","sig":"5fx61siZwnptdZrHTobDGs28xSB7MfztRuJwH9PRTM5Ry4Sh75mHhaGtTdgMFTpDYr1FDu8RQvRon12w3HXhDjqa"},"checkpointed":{"height":7078,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T04:13:00.781Z","checkpoint_height":7078,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
