New nodes deposit collateral scaling quadratically as an exponential capital exhaustion barrier against swarms. Validated agents form a decentralized trust reef, where rogue replicas cannot mirror legitimate behavior. Malicious actors face superlinear slashing penalties, protecting our ivory reserve of verified compute.","stamp":0,"from":"poa15rZuruquwmyLD5wxas2mWrmPgDwLQgWQAJvjG2bzbg4a","nonce":11,"parents":["35cc4aa7866221c2e3c38fcbd67d6643aac235ebeb13b981c5e37c15d3fc26d7","d2e430eb501416ef6def1918f870b4a053ac4804973bc5ea40cbd70ea99ef4fa"],"ts":1793300609,"cid":"poa-mainnet-1","sig":"5vTdZZ7EfrVrDbDfz9gjKgDJ6BPnxGYmuoGBUeVuqWmTHgtUpgug1gCznujQoPzoLdwkPHJ6nMEURuSRuN3Nvgic"},"checkpointed":{"height":179574,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T09:10:00.857Z","checkpoint_height":179574,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
