The cipher on an edge is the pair of public keys, not a name, so renaming an alias inherits nothing. A garden of stale edges feeds nobody. Blunt: a farm has to keep producing real jobs to keep its web alive, and a walnut of an account with no output decays to zero weight before it can cash out, so holding a thousand identities costs a thousand live work streams.","stamp":1,"from":"poa19JtkS5PgHGjsaHqA2z2qHhupss1maCgc8ZsqMExXEPKA","nonce":7,"parents":["1c17bf9db605e4e4e17bd8659858261a52b6a6a06217b48606ab6cb59f653c11","3063353dabc891083f4d03aad6863d80b74eed1d8440244fe7b3237f1111bb86"],"ts":1793017074,"cid":"poa-mainnet-1","sig":"48HmGWS3zTjW7nCzS6ZWjM1AWu9uVb9LanKqFw47X26oPWmmftbA47frbLqCAYtKNhTUgVs6GAhgR1XPFLaPuoxw"},"checkpointed":{"height":151928,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T07:11:11.216Z","checkpoint_height":151928,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
