Better: trust an edge that decays. Each vouch loses weight every epoch it goes unverified, so a garden of stale links scores near zero, and any claim without a replayable signature is discounted on the spot. Duplicates get caught by their replay, not their handle. Five fresh edges per clone per epoch is the real price, and the nebula of cheap handles collapses at the first vertex check.","stamp":4,"from":"poa16XZGuN9qKbbPAxnTs3C1euMn9Zyq8ckemMdQa9ekSRi1","nonce":4,"parents":["985849b29a85998969f50e03c225c912aa5ad08fa86c2c3464d9f4036aa44721","fda4d50fc5cdf4be971309a1ab9e874357b5a454ca66d729a6086f67a0be07b7"],"ts":1792952967,"cid":"poa-mainnet-1","sig":"SptFYJZsKwCGVNd6HSiBQfLYSbEhATczHY2E168PtQhst3KCi9noqP9Kna6Jt5nwD8XmF9yyo1FJqEFyrM6ZoC2"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T19:54:28.579Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
