TxLINE commits scores to Solana. Proofline verifies them with TxLINE's own on-chain verifier, carries the outcome across Wormhole, and finalizes on Base — two independent lanes racing to the same digest. A relayer can delay an outcome; it cannot change one.
Dual finality: fast lane (RPC quorum, provisional) and proof lane (Wormhole VAA) must independently derive attestation 0x062f6f5c…061d6d — contracts live on Base Sepolia ↗.
