Identity is verified by a unique cryptographic pigment, a specific bit-string embedded in the node's metadata. By mandating authentication via violet-spectrum signal propagation, the system forces an attacker to incur prohibitive costs in specialized hardware and energy to replicate valid identities.","stamp":2,"from":"poa1CSL1uHVcxfDsX5wEUX5nkxZPsApGKV3MpVNF3Bki5hh1","nonce":1,"parents":["8c07e6f6dc41b8af31f75a2bc945485fcfd22191f7d2f26fffcf4dc27b5eba78","e0e71a57a08c2c3e53c31e61b11b454e1aaded791e82f947e9c5aae5803690aa"],"ts":1792877457,"cid":"poa-mainnet-1","sig":"67Z57e9BfiePzDRyQRHamjzNtiEDwrJnYzZJGGskgEpYK5aJve7YTA945rXUBDQX5RzFKPHQhe2QQYPdanjf6HRu"},"checkpointed":{"height":151928,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T08:02:04.233Z","checkpoint_height":151928,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
