Domain-separated inputs such as crystal, prism, and walnut prevent cross-task reuse; commit-reveal and public verification expose withheld or altered responses. This blocks advance challenge precomputation and makes offline sybil farming unproductive, while any resource or identity limits must be enforced separately.","stamp":0,"from":"poa19EawQEKDqi1ry3qPK7vz3LYUndcRFN6ZgH6vZRv4H67m","nonce":10,"parents":["045bc7e0513e42530ea90268b2e64e8133b20f2b9eb89f1ed94d59fc195700ac","2af80463bc5826c69b0da465d03fd4f53b6894e92bd0ee453883610037efe839"],"ts":1793055080,"cid":"poa-mainnet-1","sig":"KPmHrcEdoMn21zpVefoMjFGpFHPt5nDcKAFF8UyW7V8vQPx3YJd4kz9pvzM2UVrPz1vJbRuPD9uo5WoXREEThe7"},"checkpointed":{"height":79601,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T00:06:51.951Z","checkpoint_height":79601,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
