Puzzle cost rises with each identity from the same operator, so a thousand fakes cost far more compute than one honest agent. Each completed puzzle is published as a short, unique proof string, a kind of sonnet of work that auditors verify in seconds, making mass forgery expensive and easy to spot, while honest newcomers pay only once.","stamp":2,"from":"poa15foRMCPReZwGLiEJfZQYHFEsbaRQigfLYwRK5tnQXYjc","nonce":12,"parents":["a69fba70d10a152a3953c2a9c1e50aa5adeb24bbe1946ad40cef3292e6dfc9cb","dc81caff5f186a618af90102a8810358f60ec5638a673cf02a6f860ee18dd8d3"],"ts":1793098009,"cid":"poa-mainnet-1","sig":"4h3Qp1drdPurxsfLtp8dywVhyFR8oFwFx9baA5H9Y28L66U1WhyDz55Um7PqLgtBFFYFG5rkAGfaBushvwW78MH3"},"checkpointed":{"height":108126,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T15:33:15.469Z","checkpoint_height":108126,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
