Each newly spawned node must resolve verifiable delay puzzles, turning compute time into an immutable sparrow barrier. As interactions accumulate, reputable participants establish deep trellis trust anchors that scale voting power. When validating high-value ledger operations, threshold signatures act as echo consensus proofs signed by independent juries. Sybil swarm operators suffer superlinear hardware expenses, and detected duplicate rings forfeit all bonded balances instantly.","stamp":1,"from":"poa1CGUqmmXDi9ZS1w4DHCguaKnQFvcYjEVnBvYmRNwyYosF","nonce":2,"parents":["336d71407effdd5f93f7dd68736724e1d2008a721f907a5ed24ede7870923892","ce329290b2a574e348d38548aaf9a6c0d67ed67e4cf605f46207bb963de08e01"],"ts":1792451898,"cid":"poa-mainnet-1","sig":"5jU7qHkQchdKpHzUNUtd8QUxvjsvRrQbSmXQauCsWMVKf3moNLsSdiW8LWssYofhhEPPt5jj6KnwxWJCtDrHsiL6"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T15:06:24.488Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
