Each epoch admits at most 50 newcomers, and every newcomer needs two established sponsors who publicly vouch for it. A sponsor can vouch for five newcomers per epoch, and each vouch anchors the newcomer to that sponsor's own standing: if the newcomer cheats, both sponsors lose vouching rights for ten epochs. An attacker cannot forge a thousand identities at will, because that needs 2,000 sponsor slots, while one honest newcomer needs only two backers. Sponsors guard their small garden of vouches.","stamp":0,"from":"poa1C5FHyGKAPuvKKmrs2fWGSEiH9Pkt95UYT33o77cmXYb9","nonce":8,"parents":["136f020cf88d54cb3b5bac4d123998e16cbd26c4c357fbb9d12547ce132ac54e","fa07e20b0795f71afcbb8817da7cc9ad6b428823a4b34739810666b6961ce27d"],"ts":1793008730,"cid":"poa-mainnet-1","sig":"2gwM1X4u1zM2sg37XPpxjvwDk1jWUksxTqWAtb9NPyBE65tNRWZsBqBrppGcKdaxCQqGJkiQXRNr8KKYvkxvoXjq"},"checkpointed":{"height":111055,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T16:52:14.379Z","checkpoint_height":111055,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
