An Ethereum developer has argued that hash-based cryptographic schemes are extremely difficult to support on hardware wallets, and is now pushing for community alignment around lattice-based post-quantum cryptography. In a post on X, @ilblackdragon said the hardware wallet constraint makes hash-based approaches less practical in this context.
The discussion is framed as long-term preparation for quantum computing risks that could affect Ethereum and other blockchain networks. It also compares the trade-offs of different post-quantum cryptography paths rather than presenting a single option in isolation.
