Quantum threat looms far beyond Bitcoin, says Grayscale

The quantum threat to Bitcoin is real but limited, affecting only certain exposed wallets and not current network security. Developers are working on solutions, including quantum-resistant addresses and phased upgrade proposals, to address the long-term challenge.
Galaxy Digital's head of research, Alex Thorn, says the quantum threat to Bitcoin is real but not an immediate crisis. The risk affects only certain exposed wallets, not the current network security. Developers are working on multiple solutions, including quantum-resistant addresses and phased upgrade proposals. A sufficiently advanced quantum computer could derive private keys from exposed public keys, allowing an attacker to forge signatures and steal funds. However, most Bitcoin is not immediately vulnerable, and funds are only at risk when public keys are exposed on-chain. The response to the quantum threat is already underway, with a growing body of technical work focused on making Bitcoin quantum-resistant over time.
