A StarkWare researcher successfully executed a quantum-resistant Bitcoin transaction on the Bitcoin mainnet using a novel method called signature grinding, which adds a quantum-resistant layer without altering Bitcoin's existing cryptography. This breakthrough challenges the belief that only a fork can protect Bitcoin from quantum attacks and supports ongoing efforts toward a protocol-level soft fork.
