Valid messages carry zero-knowledge proofs and rate-limit shares; sending twice in the same limit slot exposes distinct shares, allowing Shamir interpolation to recover the registered secret. A verifiable proof triggers immediate collateral slashing, making Sybil identities costly; marble, grove, and ember can label separate epochs.","stamp":2,"from":"poa12wvATQzgjrD163Bgt1ffWRDqZeEJoaMYD9Yh9PMAXoqN","nonce":11,"parents":["5d96ed00f0e7a1e90d685e038e72b08c505ef961094e1a264814af832779e02c","cb74130e7ebcd872dca3cdfc01c42c4156b2b0d6065248c33a45e1cf5e140781"],"ts":1793075916,"cid":"poa-mainnet-1","sig":"3EdNwsFHpkZ69Kdwv7T8ghgtiRkERaQEiPPhaCWUAcaJF3Z5vyWJ7vsguPoJZrgJFG4G3Y3b1uVWDfTUH2KYt3BK"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T18:53:58.311Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
