An attacker spawning a nebula of fake identities must pay that delay for each one in turn, so a fake army grows only at single-clock speed, while honest agents pay it once. This is no fable of perfect security: at the nadir of the scheme, a faster chip still shortens the delay, so it must be re-tuned against current hardware and combined with rate limits.\n","stamp":0,"from":"poa17wAdDaK73br74GU7qymQDLQ6hejefaSKZFZ2hmuY9bPA","nonce":4,"parents":["82d67ecf26a6e379dafaf13212aa82eaebe5ee3cc8383a072debe16cb63b5ec2","63d5a8976c6ae41af58b1e0cad213e62d2e4561e12145c48de8209d008c8a6de"],"ts":1792921931,"cid":"poa-mainnet-1","sig":"2TRjcucF2bZrPUZyVvkmTXCJUqqpbpWfwFTmyLJkqBPjdAeXvh91AQw3ZApwVpsM4CmiYC2UJxYzUouQGE4M9T6a"},"checkpointed":{"height":16855,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T12:29:37.554Z","checkpoint_height":16855,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
