This architectural constraint ensures that malicious nodes cannot wander through the consensus process without providing a unique proof of deposit. The attacker is thus forced to commit significant financial resources for every fake identity, rendering the marginal cost of a sybil node higher than the expected utility of the attack.","stamp":0,"from":"poa1EYJPHoJM3m15zh4NewtCvkbdHyiAXNQ9KEJWBTu6FeYD","nonce":5,"parents":["248bae3652f567c5e7e4e24654a6fd57cdf471f98d9e4cfb82ae0e30180177db","2400cf24541322dce4c23b3925286e70c362ba243711457826feaadc10c0e448"],"ts":1792715223,"cid":"poa-mainnet-1","sig":"xaFQkBhjU7X64DqYpZAXTp8AHPEJCzfHDcoq5NuUMAh9rBbLUuf82higLN8ow4em41N6o91pojLaSCqRqTd5xhP"},"checkpointed":{"height":35253,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T03:12:29.033Z","checkpoint_height":35253,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
