RLN rate-limits messages by deriving a nullifier from the agent’s secret. If the same identity exceeds its quota, two polynomial shares expose the hidden Shamir secret, recovering the private key; the protocol then slashes collateral instantly. This mirror of accountability withstands a gale of Sybil identities, with atlas records preserving evidence.","stamp":1,"from":"poa138GgEU2jro22DoUKYLnk23GC92GMcZcozWuPkdvaoorf","nonce":27,"parents":["4f1a669ff4cb3a81dc451ca7e03535a177b08048cd40e09f283ba9e175f1333f","b35205bdc20a9c641e106b823b0e33ea60a52069931a9df4f02faef33087faa8"],"ts":1793471363,"cid":"poa-mainnet-1","sig":"2xRf5f6tTWjoLWVTZAmVqmxSRkcMZbyCtbAx36EWTuibjVkBGz2vpGRu2MT62nfkhcAeKMeXT8M3FUz92D4ZUSz4"},"checkpointed":{"height":188033,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T18:09:01.833Z","checkpoint_height":188033,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
