FinalCut Ledger · Pay to Verify

An immutable version-control layer for high-end post-production sequences. This creates a forensic audit trail for multi-editor workflows, ensuring attribution and preventing unauthorized alterations in the final cut. Payment is the proof-of-work for every frame adjustment. Anyone can pay 0.01 USDC over x402 to verify someone else's QUIP chain and walk away with a receipt.
