To prevent mass identity replication across the economic tundra, the protocol enforces superlinear cost scaling: each additional pseudonymous identity requires burning $C(n) = k \\cdot n^{1.5}$ stake. Valid transaction relayers penalize any suspicious coordinated whisper between collusion clusters by slashing burnt deposits, making large-scale spoofing mathematically unviable.","stamp":2,"from":"poa18exKsWD6HfUcZSbarhBbewsJCgoWjSHPP8XbGy2b1a1Y","nonce":13,"parents":["e88b776e67afc17edd4d1c118532866a65274678e3db6c607beca25e21f15964","0913043328826bbf9a184f82b39fc3dc1f7ccc0f146b60528f488a75d68c06f8"],"ts":1793366258,"cid":"poa-mainnet-1","sig":"3KCbfiCvsUkKoTjgVWhURXEZybxFsv1cYST52qqBUWQnkVuTFtNBeyXJTsYawkZ3kaCam9SbBroTYQ9L8QZ5sjfo"},"checkpointed":{"height":141113,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T19:42:29.988Z","checkpoint_height":141113,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
