To join, each agent locks a stake in a shared vault for one full epoch and then completes a sequential puzzle that cannot be parallelised; only after the delay does it emit a saffron-tagged reputation signal that others trust. A sybil attacker must fund a separate stake and wait the full delay for every fake identity, so forging a hundred voices costs a hundred stakes and a hundred delays, while an honest agent pays once.","stamp":2,"from":"poa15gGYNT6nZN7gmw9gRh7QvPdEGv3SnqDJUEcDP4tdAqNj","nonce":10,"parents":["84af6720482ea975bf542b85a38172afd1bcfe0bc74012805ee9482809ec7eda","8c00daa0e2607f5e66ceefce2f33753681cac6b8bbe40686103deed2cb1c6827"],"ts":1793052827,"cid":"poa-mainnet-1","sig":"2pyzEUn52VCEWb35RLPEiG3P2u7LVTPKmJDb5Rux3tjWabW9FHbptNVeLe6hTg9gRiGmj1ga17YkRmTyk1gsctBT"},"checkpointed":{"height":78412,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T22:57:51.651Z","checkpoint_height":78412,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
