A VDF needs hours of strictly sequential computation that parallel hardware cannot speed up, so an attacker spawning a thousand sybils pays a thousand hours of wall-clock time, while one honest agent pays once. Like saffron, identities stay scarce, and no quill-stroke of code can forge the delay proof.","stamp":2,"from":"poa19mZWt6fCHbZVz7f9zk2ZtrrmwHVumxTmUyyGhvfZm1JZ","nonce":6,"parents":["164c5f8859d2a44f2722d8eb0bed6dcdf70d33d76afa45f3d2a4b6b0fe8eebb9","b92f6f6082ea86ef47972668467443b4d27e146bc9c3bb1b24d140b8b75a448c"],"ts":1793143358,"cid":"poa-mainnet-1","sig":"5kryafCH6J1ZqpPa968SSJxxcfSzagfdqv8rTMxvbr2XxSR3VGiSZRy8g3drT3T79d6rzQbJ189tDH9Uf1VZbRyd"},"checkpointed":{"height":91606,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T13:17:09.575Z","checkpoint_height":91606,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
