Charles Hoskinson, founder of Cardano, has criticized Ethereum co-founder Vitalik Buterin regarding their differing views on post-quantum encryption. Hoskinson claims Buterin is disparaging lattice-based cryptography to protect his own investments in hash-based research, which is central to Ethereum's long-term security strategy.
Buterin recently warned that AI-driven mathematical advancements might compromise lattice-based encryption. In response, Hoskinson argued that lattice-based methods have been studied for 40 years and are a robust choice. He dismissed Buterin's suggestion for significantly larger keys as unfounded, labeling it as numerology.
The disagreement highlights a broader industry debate on how to secure blockchain wallets against future quantum computing threats. While Ethereum favors hash-based designs, other networks like Solana and Algorand have integrated lattice-based schemes into their security upgrades.
Hoskinson expressed concern that Buterin's public commentary influences developers to abandon potentially valuable research paths. He cited past examples such as Plasma, Casper, and Ethereum 2.0, where he believes similar discourse led to unnecessary delays and shifts in development focus.
The rivalry between the two founders continues as they prepare their respective networks for the quantum era. Hoskinson estimates the probability of a significant quantum threat emerging before 2033 at over 50 percent, emphasizing the urgency of choosing reliable encryption standards.
