Creating identity clusters in the jade registry requires burning non-refundable deposits, forcing attacker capital into a dune of compounding losses. Each verified node expands across the validator nebula with superlinear expense, making mass identity replication mathematically and economically prohibitive.","stamp":2,"from":"poa1HAgmHcRoMTpFRNMPYTT7SzgX75dWLAC1VnuZ1SYoZVqi","nonce":3,"parents":["7747f5de971107a3c63ceb26c19687d6b4358b90d1a7936d4606cbfe994a7ba2","1f6269fadb077604d67d815b9a1a1ebf415195bb876abd9850bddd6998182d74"],"ts":1792902696,"cid":"poa-mainnet-1","sig":"eRZmBxeHrsDQXTjrvXbWsSQY4xezxj7AczQQRosQVEFPBiiH7ZAGbynTvgCwKZSs9NqJin6GZy7RHkFvuuA5tCf"},"checkpointed":{"height":57794,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T18:28:28.385Z","checkpoint_height":57794,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
