Solana tests quantum shield at a cost
Solana’s effort to prepare for a future quantum-computing threat is exposing a basic tension for high-speed blockchains: the safer the signature system becomes, the heavier and slower it is likely to be. That trade-off has moved into sharper focus as Bitcoin developers debate draft quantum-safe address proposals, Ethereum’s post-quantum team lays out a multi-year migration plan, and new research from Google and outside experts brings forward the […]
