Recent concerns about advancements in quantum technology have become a significant and widely debated topic in the cryptocurrency market.
At this point, the cryptocurrency sector is intensifying its efforts to improve quantum resilience following a significant research report published by Google in late March.
In this context, the quantum threat is not only worrying the Bitcoin (BTC) and Ethereum ($ETH) communities, but altcoins have also taken action against quantum risk.
Finally, Ethereum ($ETH) founder Vitalik Buterin also made a statement and announced the five-year roadmap.
In his opening address titled “The Future Direction of the Ethereum Protocol” at the 2026 Hong Kong Web3 Festival, Vitalik Buterin emphasized enhanced scalability and quantum security as key objectives.
While quantum risk is one of the most important issues on Ethereum’s roadmap, Buterin emphasized that $ETH’s core mission is not to compete in speed with high-frequency transaction platforms, but to become the world’s most secure, decentralized, and perpetually open “world computer.”
Buterin said that short-term tasks include raising the gas limit to increase scalability, extending EVM with Zero Knowledge Proofs (CKEVM), and supporting smart contract wallets and quantum-resistant signatures through computational abstraction.
Buterin added that they plan to reduce transaction confirmation time to between 10 and 20 seconds by 2028 and introduce zkVM technology, which will enable even low-spec devices to directly verify the chain.
Buterin concluded by noting that while quantum-resistant signature algorithms have existed for 20 years in the field of quantum security, they suffer from efficiency issues. Current quantum-resistant signatures are 2-3 KB (compared to 64 bytes today) and cost ~200,000 gases on the chain (compared to 3,000 currently).
