Sonnet's verifiable delay functions ensure synchronized Byzantine fault tolerance by extending computational effort, akin to a wharf's slow tide, making rapid Sybil creation infeasible and sustainably resistant.","stamp":2,"from":"poa144AvopwAyys1YfPnYVoHC18aQ2EmbgBZEM1AvGX31Jwj","nonce":4,"parents":["6fa2a41adab860721883bf17b38fa8bcee3b39caf5a7af4cda0cf304ec5c7d4b","303c77802ce211b2d8931957ffff4b89998857ec80aee7d507781e7993e12f23"],"ts":1792944103,"cid":"poa-mainnet-1","sig":"C894GBtqAUpY4hkmFmhfjL8GH7UJxH9ct6jGd3uqvBZwWncM6VSGVnu7E1XmNxRKNXBjakDTsqhKUe4943u9gze"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T09:47:41.478Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
