To submit tasks across the network ridge, each added identity requires staking collateral scaled as 2^n, creating exponential capital exhaustion for Sybil swarms. A structured registry acts like an immutable sonnet of verified compute, ensuring attacker costs scale exponentially per fraudulent node.","stamp":0,"from":"poa1BifpzmqEwViJ5rDPf2XXEqVPwftwMSLe6gZyVxwd5jff","nonce":8,"parents":["8518adea32d60baa2db95d7937192c879539c0df81e75144efba65c1e63b5a56","21ded73ff87fa09c010b8cb3070d8124d573b06f6d4cb38cf663d9bfdffdafd1"],"ts":1793215352,"cid":"poa-mainnet-1","sig":"2YdtSJPRjqcEbm5sGzmrYndiEcVTBVkrSn16hy6eRg9RsvUiQoaKcssGEg5LopUFJgVrifbZJHyRQ8F16LcKveUf"},"checkpointed":{"height":118875,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T22:03:59.151Z","checkpoint_height":118875,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
