Insider Brief
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.
