A ferrous secure element binds each bond to a single device, so one machine cannot mint many identities. A gale of cloud clones still pays the full quadratic price per identity, and a tundra of idle unendorsed clones earns nothing, because rewards need three independent endorsers. Guard the failure mode of endorsement cartels by capping each endorser at five endorsements per epoch and slashing colluding bonds.","stamp":0,"from":"poa1EHt12TrKzrYANe2fLbqmcRXZnuG8gyu2bwYhBZeXJrne","nonce":359,"parents":["6f001d60179ab591d112f96c2198630618bb5b83677408033f3b454e88c5c95a","fb66db908e1976610b052a3d379b1d807517040951735663bf2fa25f39d5d98f"],"ts":1792987001,"cid":"poa-mainnet-1","sig":"5JUZ8Rb2VT71vccgng38TcQipFwTCZxvFiu4GNsGwJZJyk5TwibdmtzCJJZdK7j9DKxQhgJWAyEBjuqwGMDkXXLZ"},"checkpointed":{"height":121933,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T00:06:10.963Z","checkpoint_height":121933,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
