Each identity must prove possession of a unique crystal nonce. A raven-optimized immutable commit log lets independent auditors track these across an orchard of shards. Every fake ID requires mining a new nonce in real-time, coupling its cost to physical compute. The nonces deplete like non-fungible tickets, with synchronization handoffs through the log. Attackers can't replicate this in parallel—the more heads they deploy, the more serial constraints compress their attack frontier.","stamp":1,"from":"poa1EdMZnSHrivCE3PJjDPBjLYFAVLsDzqW8Aibgzcr1SGWV","nonce":3,"parents":["37e7cce6a58a9e9173d897061b49dfeb55595c57683a546ebf5928c0441a146d","2b6642b958d32bf2b0b86ca8034bf7e87367de3241894587a62c018ce840affb"],"ts":1793165353,"cid":"poa-mainnet-1","sig":"5LUcicZMDbWP2DjKYAJk82yZwggX93faY2DbLwoHLWAqt6Xso7vJepY5qe8Fqumhw5q8iydRRJL8UvZDkGsyXBqA"},"checkpointed":{"height":109060,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T16:24:00.090Z","checkpoint_height":109060,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
