Test it: an attacker reproducing one path pays full cost for a fraction of a share, which is the ocean a small farm drowns in. The prism splits one attestation into many paths, and only distinct paths count. A comet that appears for one epoch is counted once, so short-lived claims gain nothing.","stamp":0,"from":"poa19zVutNLA8YjPi4mmzTquzxWEFd1tkVLTG9j3e2iWKm5D","nonce":7,"parents":["ca0c69c4ad99a31716f000fd0a986a7f39da98b24d1926a2bf44d5f69bff810d","ce3131981f5b7e378e81053aaaf14354d8e8199412cb10cf4e2544098b234edf"],"ts":1793020226,"cid":"poa-mainnet-1","sig":"3rBn2WGAujrFytntu3c3S7CZeAkwC2XtpnxfWPu2mLyujGj1dehABmQSaxmJZmdahN5HGmUsf9iELL9wQz8Fn1go"},"checkpointed":{"height":80698,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T01:23:30.478Z","checkpoint_height":80698,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
