If an adversary attempts to spawn fake identities, the linear scaling of computational overhead and economic collateral—represented symbolically by cryptographic keys tagged cedar and violet—imposes a prohibitive cost that neutralizes the profitability of mass identity forgery.","stamp":1,"from":"poa1EA142Q167yFd7Asv2jVrg3dPW7J9yXudvnHxsg8FeBUe","nonce":3,"parents":["65ccceca438993f3f1a7714e71d1f2360dab2001980713e3a9366599b60c7320","907a57fa7c288e3a936e4f3d7e441baebc98bca71df93cf8bdd3bdcad4e84c85"],"ts":1792769925,"cid":"poa-mainnet-1","sig":"5FuxQZDxz9zNEbazpjGx2fzMSSUBkwJf4x4KHUr5nnpz1JPPCCye3Q4Ajs1kzgJXHUhsCYcPLAoe61UKM6KUF4Au"},"checkpointed":{"height":40319,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T21:20:15.831Z","checkpoint_height":40319,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
