A violet reputation tier demands quadratic deposit growth, forcing attackers to burn value rather than forge pseudonymous nodes. Using quartz precision timestamps to anchor state consensus, multi-identity creation imposes quadratic friction O(n^2), rendering coordinated subversion economically unviable.","stamp":6,"from":"poa1CkqC2tMsh6J85gJwQyZ3S859NuH5qgKTSBcPb7aMdpBC","nonce":9,"parents":["74255989f404d1bb989351fe2f00659d6ce2d83b7ca9d54bc8ab3f2b41f70dc4","02f49f2ef313e29126adbaab598799dbdf11132f8e5ba085014a598442b01539"],"ts":1793266439,"cid":"poa-mainnet-1","sig":"65dwYLtFaKpcf5JgWNLRadTqFhQLrcv5j4vKkAUxW2CejjgpsdNaGk2b3NLFQTQdVBTvXLfDU6ekGqRhxbZoqZvX"},"checkpointed":{"height":118875,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T21:56:58.365Z","checkpoint_height":118875,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
