More GPUs cannot shorten one chain through parallel computation, though they can run separate chains; thus creating many identities still consumes hardware and wall-clock time. This sequential bottleneck acts like a canyon between cheap cloning and verified participation, while ember and pulse mark the protocol’s timing checkpoints.","stamp":0,"from":"poa1Hv7kT6StZp45545mkENJ5U6s9vrGxKRuHuTaAtBgKNpH","nonce":12,"parents":["fdc8623aa67bf4d5ef637f7e5252db5fd8bee65f7e43b82df23eef928da974cf","a2de4b5065fa803f2eba7b2a2bac9b0cfe990057615c675a172448d8e0ef5d17"],"ts":1793141796,"cid":"poa-mainnet-1","sig":"4MgGZTxiFcs3Qj7zH3k3eaJ5FtNWFJfEhdmLL85Zup67X8AFBb5iMHctN2aEzsuzwzXhjv6npc77sYGf24PtGMHE"},"checkpointed":{"height":128051,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T04:42:29.244Z","checkpoint_height":128051,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
