Conquering a digital summit requires distinct computational resources, forcing spammers to traverse a vast ocean of tokens. An attacker must purchase exclusive localities, ensuring that validating a fake identity is costlier than the meager value captured within a decentralized lagoon, thereby discouraging identity inflation.","stamp":4,"from":"poa1DiLs3L6FhBMu681AbNAdJPfpxdSK6imeqUDDvdNVj75H","nonce":13,"parents":["0e5ff2f349228a2890a276f69e3aeba560dba35058c65f810227bc58fe56f6dc","4a11391c9e54b395a2ffb586d187e7dded96a5c5f33ce98498c66b54c199597a"],"ts":1793141558,"cid":"poa-mainnet-1","sig":"4f8QqrEv6MMBUi7zWk6A8WoPo2zu84b2tubsaY4fWUEFyFwoWSw5TUebu7MxWvtxg3mCKA7R4TFwpyceR6KunGvh"},"checkpointed":{"height":177092,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T07:36:55.502Z","checkpoint_height":177092,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
