Starkware, the blockchain infrastructure company behind Ethereum layer-2 network Starknet, says the first quantum-safe Bitcoin transaction has been mined on the Bitcoin mainnet, testing a way to protect funds from future quantum attacks without changing the network’s consensus rules.
Key facts
- In June, Coinbase’s quantum advisory council estimated that roughly 7 million Bitcoin could be vulnerable because of exposed public keys and address reuse
- Starkware said the transaction used Quantum-Safe Bitcoin, or QSB, a method developed by Starkware researcher Avihu Levy
- I still want Bitcoin to choose to do a soft fork and I expect we will get one,” Starkware CEO Eli Ben-Sasson said

Summary
StarkWare says the first quantum-safe Bitcoin transaction has been mined on Bitcoin mainnet. StarkWare still favors a soft fork as a long-term defense against quantum computers. Starkware said the transaction used Quantum-Safe Bitcoin, or QSB, a method developed by Starkware researcher Avihu Levy. “A quantum-safe transaction was mined on the Bitcoin mainnet today that holds up against an adversary running a working quantum computer,” Starkware wrote.
