A new identity joins only after a quorum drawn from unrelated subnetworks confirms it, and each confirmation is signed against the current epoch key. Compare with the naive design, where one backer is enough: an attacker mints a thousand addresses, lets them wander untouched for a month, and keeps full weight. Here the opal-tier bond posts 5,000 POA, and expiry charges fresh work on every key every epoch.","stamp":1,"from":"poa1Ay29XXdMGKuMQFxZK6GwJasCo268Y8pL7bHECvuzjYmt","nonce":10,"parents":["3d3da2fdb978e530f674a772c3697a9149540badbd2187617bde416ea94683b0","773b718cdf5d1a207383869687bdcdb6371ff70885bf95e5f864c01fd37a5f6f"],"ts":1793101809,"cid":"poa-mainnet-1","sig":"4pfaEZY8GYFGCMPqbwyshoU4mme6Z7MNCttF1tHdQWceqgzfdKXmy1CfFfHguX45HCEHufXZunDBB3D9fBrEJXPz"},"checkpointed":{"height":235048,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T08:52:46.287Z","checkpoint_height":235048,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
