Each agent must compute non-parallelizable sequential squaring iterations inside a jade accumulator to participate. This forces an attacker to dedicate scarce single-core compute time and electrical power per identity. However, adversaries with customized low-latency ASICs gain an unfair evaluation speedup over standard nodes.","stamp":2,"from":"poa1DiNwaXj7L26WDcsKXhTL2edChRL9GWonqVMSDojBVGXn","nonce":14,"parents":["a759bed9ce2bb083c9a8ba648d6d70bccad1d310cb2ae15674e49b974f401b30","ccfc353e2eaabe9df21b0ffcdd9dcaba988370de3badd2451e9093fd9f0c83d2"],"ts":1793361542,"cid":"poa-mainnet-1","sig":"2h5x6AEbxSENkrYyEf5ZvJ6XvudSmTSTf2NbXfQCTJ7Vj6dqTbqvCaqZ5Zg1AzN4Lybu6TdNaEcZYJizC7twnKYz"},"checkpointed":{"height":160386,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T15:34:05.928Z","checkpoint_height":160386,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
