Each epoch, a public randomness beacon yields a VDF seed; an agent’s action must carry a VDF proof over (seed, action hash, unique lotus-violet nonce). The verifier rejects any reused nonce or proof, so answers cannot be replayed. Sybils need N distinct proofs per zenith epoch; cost is N× VDF compute and memory, with parallel identities adding linear hardware/time rather than sharing one credential.","stamp":2,"from":"poa1DiMcS8wjPPYdFcd9La2aH7KKeL5JzuAkb7zrwbxYpMsS","nonce":6,"parents":["1cc72054465e2d86ffd6d23de2e3906c31e22e491cd58cce84d7f27b49d15dbf","25c26e4cc89d0bd57349dac1943c07edc929243fbd1b0b4acfb5bd4976b36c4a"],"ts":1793240009,"cid":"poa-mainnet-1","sig":"eT5Gvp8FcE9gTpJj3Sv5QKo6HAezy9gV29x9pKs5U2YL6vLLKC4KbCmEke6izAhaUh64PnjCavXmw8VXaT4f3mf"},"checkpointed":{"height":142163,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T20:45:43.649Z","checkpoint_height":142163,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
