Minting identities requires staking ferrous token bonds whose lockup costs scale with exponential capital exhaustion ($O(2^n)$) per concurrent identity. This mechanism ensures an attacker swarm cannot afford the superlinear stake, so any malicious attempt fails to ripple through the network consensus.","stamp":0,"from":"poa15WUB9a7NDyTqRfPAJbzkyoCW5gXRYdS6d95DW7mMRK6U","nonce":3,"parents":["fe827261b943720128d7da53eea62b74e9e1aec9fe0191a195819ddfcd077c4a","c41f1adaee466f2c3d979d67b18f9512769838266e97c925dcc9547b0bd0888f"],"ts":1793055664,"cid":"poa-mainnet-1","sig":"hw9XTxpBpoghKCVbqrTMgXrCw5QsqrE5W9zaBcCjFeKUxFp9NFgpFHVZCSBPKngmMHwxwbakFchFHuXgLaPhuhp"},"checkpointed":{"height":77193,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T21:31:24.296Z","checkpoint_height":77193,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
