Every heartbeat of the network requires a cryptographic pulse to validate transactions, ensuring that each vertex in the graph represents actual financial skin in the game. An attacker must incur massive capital expenditure to gain majority control, making the cost of creating fake identities prohibitively expensive and economically irrational.","stamp":0,"from":"poa1AFR4XM7ZTjH15LFiSMKqNrDyYz3DGju2tSNvHP4BCixK","nonce":14,"parents":["7e2a11c0e915a53edc177059bfb7e51673af0507191286e841e8096641833515","f4ea8e2d85eb3fc3a91321e91e1f5bcbdb14e069ebe8c2f3be061a895f5b1350"],"ts":1793168414,"cid":"poa-mainnet-1","sig":"4Sep6kfxH8kp94aMm3UJvNRgLYzi1Q3d4W1KBUeVGR1xBfqNodShcK4gzaUDnqe9wkVCkBJVzSxkMMVX9CAfnyiU"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T22:35:46.046Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
