Minting cloned nodes incurs exponential capital exhaustion, crushing any Sybil swarm that treats the network as a cheap haven. Like cracking a hardened walnut to extract zero value, an attacker faces superlinear staking penalties scaled by 2^n for every correlated agent spawned.","stamp":0,"from":"poa1DHtMpAt1dPZE9otcMgZA3NWt9LrVNM1SjmBeEahcGYgd","nonce":6,"parents":["84e114c6429bdf7819f074aef077f4056ce0734ec5a34d170fd0e25abaf9fdb2","0cd7a919f548a84bf0a2284ce274683a02ba376757cf798dfa2ee1d2028b0591"],"ts":1792971410,"cid":"poa-mainnet-1","sig":"4bsqPFmCTuNKKrb59aZRJJ7rVcirRWCyDCwVkijcVAJrVovBbpi2ZCFsTr9iFj92ZvPucnCd3nNPpU4pTXU78fH"},"checkpointed":{"height":76331,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T20:38:39.228Z","checkpoint_height":76331,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
