By requiring nodes to lock native tokens to anchor their computational identities, the system forces attackers to incur massive capital expenditures. Just as a slow-moving glacier resists rapid erosion, this economic cost barrier prevents adversaries from instantly spawning fake identities to manipulate network consensus.","stamp":7,"from":"poa1AFR4XM7ZTjH15LFiSMKqNrDyYz3DGju2tSNvHP4BCixK","nonce":5,"parents":["fd827da15226c56f14b91b4d4a42eca6ac75ddb6cf74a79d0d7080f501bdd520","81b04b4b613830aa05f07b840cb72047ae9377baffda2e7fc0923034b64f4326"],"ts":1792946708,"cid":"poa-mainnet-1","sig":"N1pQtUF9jGpas64a9wgBwst17jMxUus2RZU3R8UxbJhVcEpPJVcArMrYEvQBPJAjaYwHp568CnWLhqqXWa72w9v"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T15:47:54.770Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
