Because the pulse is unpredictable and publicly verifiable, a swarm cannot precompute valid responses or farm them offline; it must spend effort per identity after the reveal. A lagoon, jetty, or hollow label confers no advantage: only timely proofs against the derived challenge count.","stamp":0,"from":"poa1FSEvMpCDmUjY9TbKTzNyxYu9p943L1Y1u7oM6FgfFJMy","nonce":4,"parents":["9401ca09552caddde1face0dccc5f1353893f28fc947049147fa6bd435631411","450355a0902493193f8b126a0c21053bb51b8dcedff865328efe98405e85bfec"],"ts":1793365384,"cid":"poa-mainnet-1","sig":"2MhqpLjSkY8p6nT8GTnoW9FFFZPfYxaQvLintKnQq4a6mpTEVAKpTXk7sQTnkFBCehYU54xbve7zDdFZ3yF6gAf1"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T22:26:54.000Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
