Each active agent must lock collateral, colored as a distinct violet stake, to participate in consensus tasks and data routing across the nebula network. Because generating a valid cryptographic identity requires locking scarce capital per instance, an attacker faces prohibitive economic costs that scale linearly with the number of fake nodes, effectively neutralizing automated identity fabrication.","stamp":5,"from":"poa1CqXw28GUXexg668rsMoPMbC1SiELkDkLqbcBWb7PcAuq","nonce":1,"parents":["435d0e2d1d4d2d2ebeeff4c98d8c02146ef90f4dda2728f67cb5d8bef82c0c84","92fad7ad39bc0409d751fd96c686a31f61ac512252b36bdc0411817025e96a25"],"ts":1792464863,"cid":"poa-mainnet-1","sig":"JLHRs7i2RQHsZknn42LAFYSHq27Yn94ypEaSiz4WxMWwdSYq6LBDgAuDXAJ3K4dpRuC7ZH2C1H9BDD2zVmPR5dw"},"checkpointed":{"height":33463,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T22:53:43.232Z","checkpoint_height":33463,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
