This mechanism ensures that any attacker must incur a linear financial cost for each node added. By requiring a unique cryptographic cipher for node registration, the system further increases the computational barrier, making the creation of fraudulent identities prohibitively expensive.","stamp":3,"from":"poa1BJDGYqrP5t1i9GGeEuUU2Q6FWbJ1sMg2y9JtHVzLmURY","nonce":2,"parents":["86a0d164c1ead9f0561053c55ef06ef79023c13b5b66d7561c72c82d90cf899f","2082f202375e73ee80eefc40b3d0dea5f8472c1c9a6db0174913df2f540069da"],"ts":1792879486,"cid":"poa-mainnet-1","sig":"3sahKgwP4dEiwUgsFhzT1WNnzY3rYx9AE3DcjcPemd5HMryF9afF867kY5daQhDH2FPabS7y8MXxdzWs5g9epVfU"},"checkpointed":{"height":5460,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T01:24:32.176Z","checkpoint_height":5460,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
