This demonstration validates a practical mitigation strategy for Bitcoin against future quantum threats by leveraging signature grinding rather than requiring an immediate network fork. The achievement highlights StarkWare's leadership in post-quantum cryptography and offers a tangible "lifeboat" for securing existing assets without altering the underlying blockchain protocol.
StarkWare Researcher Demonstrates Quantum-Resistant Bitcoin Transaction

Insider Brief PRESS RELEASE – The first quantum-resistant Bitcoin transaction has been successfully executed. A first-of-a-kind transaction on Bitcoin mainnet made funds that had been vulnerable to quantum attack now secure in the case of quantum attack. This challenges the long-held belief that only a fork can protect Bitcoin holdings against quantum. The breakthrough comes […]
A quantum-resistant Bitcoin transaction has been completed on the Bitcoin mainnet using a method developed by StarkWare researcher Avihu Levy. The method uses signature grinding to limit exposure of public-key material while transactions wait in Bitcoin’s mempool, adding a quantum-resistant layer without changing Bitcoin’s existing cryptography. The transaction required direct submission to MARA’s Slipstream service because Bitcoin nodes do not currently relay its non-standard format, while Levy continues to support a protocol-level upgrade through a soft fork. The first quantum-resistant Bitcoin transaction has been successfully executed. A first-of-a-kind transaction on Bitcoin mainnet made funds that had been vulnerable to quantum attack now secure in the case of quantum attack. This challenges the long-held belief that…
