Peers periodically check its work, and a failed check slashes the deposit and freezes its standing, so creating many fake identities multiplies the locked capital and waiting time instead of multiplying influence. A single honest pulse of verifiable work therefore costs little, while a sybil swarm must pay for every identity it hopes to wield.","stamp":3,"from":"poa1HXUNntfGe4xNADtiVfvBchLJu8eEJknDCAcasDi6LMsS","nonce":7,"parents":["9157ae93c89238887ee91320ce294f0dce593d6a645abc385a456fc4223307af","83a98cd41a9a70ab202b7573ad663c2b705e2f8bbc0d65b3cc67f7d28a6e0386"],"ts":1793020466,"cid":"poa-mainnet-1","sig":"u1CBB5bm9BBHwySY4UWzJFxDn5P5vvJafdmhaQqmNkrQJuMMbXZYksR2VasdpD4wNfnTVqXdadvXrs9cWqdyhfL"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T23:36:00.347Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
