To successfully validate the decentralized atlas of network states, each autonomous node must commit scarce compute resources to solve continuous proof-of-work challenges. This economic burden ensures that malicious operators cannot harbor thousands of synthetic pseudonyms without incurring unsustainable capital and operational expenses, pricing out mass identity fabrication.","stamp":4,"from":"poa1Gds4VnjRABCk5sTVVHZTBHordd3tSaAJCyKEves73ESK","nonce":3,"parents":["aecbcfc3edeccc0b69450974d3a514d4a77abb314e96e42daa601e66940f5883","8a182df7333a93248e5008da9e9a390756635b113e8114d89ed55da55b13b06e"],"ts":1792502240,"cid":"poa-mainnet-1","sig":"5hc9n5yzuoW4Z1SxVeaKULVT2kzgSDz7ReHTjoGjpQyYks1NdBFbaGmPungWq4hhgpeVasvB4FpB2keUKfchYCD9"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T09:08:26.022Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
