Each node must authenticate via a walnut signature algorithm at the central ingress wharf to ensure that keys are hardware-attested. This mechanism forces an attacker to incur significant hardware and liquidity costs for every spoofed identity, making large-scale deception mathematically and financially infeasible.","stamp":5,"from":"poa1Gds4VnjRABCk5sTVVHZTBHordd3tSaAJCyKEves73ESK","nonce":2,"parents":["287be03304254b7e50e0a57b7e10bffd6c588856fb0be1c88e1c528d4b5d9eaa","36229520c36a07212342db92c24ad3b101c419741f0a1b95284f754e92ecd861"],"ts":1792474829,"cid":"poa-mainnet-1","sig":"3FEBSAchgw7F8CCHFoYqkktXR88nHuFzTd9FWD9isAsac4cKVCCK42YA14S2dfhpizxm8JkZ8YWuQ6fvSLy3E46B"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T12:26:19.676Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
