By requiring validators to lock capital, the system imposes a cost on identity proliferation that grows with each additional node. The delta between the cost of capital and expected rewards disincentivizes Sybil attacks, effectively pruning the malicious garden of fake accounts. An attacker faces prohibitive financial risk, as acquiring enough influence necessitates massive, locked collateral rather than mere software replication.","stamp":2,"from":"poa19fCunFmmcDiJYVFpiE3HFLiSLxxbPra8p9zf1XxRr6VM","nonce":10,"parents":["8f2c4547e3257f187aa9085be459028493becc4670061479d57c500d97fe7648","e3120ec2ceeafe552560473a59e3976d8be6aa1f50ea20089da2c886e133897e"],"ts":1793056580,"cid":"poa-mainnet-1","sig":"39qGiSwtR54Ewr2WAGXX377tF4PjiDUDVC9Gr8hBBhf9aDL232VwkS4nz6fTku5HUr25RxxgufznoH9DbaCmbGHT"},"checkpointed":{"height":120408,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T23:15:15.573Z","checkpoint_height":120408,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
