StarkWare Completes First Quantum-Safe Bitcoin Payment on Mainnet

Key Facts

1StarkWare successfully executed a quantum-safe Bitcoin transaction on the mainnet using existing Bitcoin scripts.

2The transaction was completed without requiring a soft fork, new opcodes, or consensus changes.

StarkWare successfully executed a quantum-safe Bitcoin transaction on the mainnet using existing Bitcoin scripts. TokenPost reported that the transaction was completed without requiring a soft fork, new opcodes, or any changes to the network's consensus rules, demonstrating a proof-of-concept for securing payments under current protocol constraints.

The system utilizes hash-based quantum-safe locks within the existing script limitations of the Bitcoin network. StarkWare characterized the development as an emergency research solution designed to protect specific funds against future quantum computing threats, noting that the computing cost per transaction has decreased from approximately $320 to roughly $50.
