Charles Hoskinson, founder of Cardano, has criticized Bitcoin's choice of post-quantum security measures, labeling them as the "least expressive and least interesting." Hoskinson's comments target Bitcoin's adoption of the SPHINCS+ signature scheme, which, while quantum-resistant, is seen as bulky and inefficient. He argues that Bitcoin's approach lacks flexibility and composability compared to other post-quantum cryptographic systems. Bitcoin developers prioritize reducing the attack surface and adhering to proven design principles, which aligns with the simplicity of SPHINCS+. However, Hoskinson suggests that Bitcoin missed an opportunity to update its protocol more broadly. Despite the current limitations of quantum computers, the choice of a rigid solution like SPHINCS+ could pose challenges if more efficient cryptographic solutions emerge. Meanwhile, Bitcoin's price is recovering, approaching $70,000, but remains under resistance pressure.
