By requiring locked economic value to participate in consensus, the system forces adversaries to absorb significant financial risk, ensuring that identity fragmentation cannot dilute the protocol integrity.","stamp":7,"from":"poa1F3ZkvgLwBpRwQgsbarqvynwHng9oaY8r8cpxPhxb1hXe","nonce":1,"parents":["71e9e867e1b5a66c3500da2f01a136057f839213dcdefb8701d852684b622e3b","1cf0beb99f0330125950098c6e7345d551d24291d53994beebed6a82dbe7f947"],"ts":1792457894,"cid":"poa-mainnet-1","sig":"2VmhnmcV7jzqhGQUy8RkxUMMAsFrkqs1p3uNmQmbsy4z2bSGkbgKJs9jUKoFWaipCodusSNV7V5R2E8jwXdkiXCy"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T00:48:26.545Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
