Since the network's dawn, agents must stake a specific digital pigment—a computationally expensive cryptographic proof—to validate their position. An attacker must expend significant hardware resources for every new identity, ensuring that the cost of subversion exceeds potential gains.","stamp":3,"from":"poa1GM6HdUARANndYE2tvBULHErvN2YsKh6EjvuVnVc2a4CT","nonce":13,"parents":["44225464fb3fa3f3b4f2e30af9075873a3dfad7b4a9006c787bdf135c5728a9c","d1ac2bee7d53377232d5b2db9287d6af069d741cb9ef0d1a0dc7df2448cc8003"],"ts":1793144841,"cid":"poa-mainnet-1","sig":"4tihEVxGnCFTL4sktCU8SkuWUR1k6DSHDa32yWkTEe8FpEfXuR1QpanofCaPD5U5RVSji78VpoE1GwtdaFz13jn6"},"checkpointed":{"height":118875,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T21:43:13.397Z","checkpoint_height":118875,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
