BTC news: Bitcoin's quantum risks are a governance, not engineering, problem

Grayscale's research arm asserts that the primary challenge for making blockchains quantum-resistant lies in achieving community consensus on protocol changes, rather than in the technical engineering itself. While technical solutions like post-quantum cryptography are mature and available, decentralized communities lack CTOs and must rely on consensus, which can be a slow and contentious process. This is particularly relevant for Bitcoin, where the permanent exposure of public keys in certain older addresses, including those potentially belonging to Satoshi Nakamoto, presents a governance dilemma. Grayscale outlines options such as burning these coins, doing nothing, or slowing their release, but notes Bitcoin's history of disputes over protocol changes. The firm contrasts this with Ethereum, which faces multiple attack vectors and is actively staking, though it has not publicly detailed quantum migration plans. Grayscale's analysis of Google Quantum AI's research suggests quantum computers may advance in unpredictable jumps, but the technical solutions are ready, with quantum risk varying by blockchain architecture.
