Gate News message, April 20 — Vitalik Buterin, Ethereum’s founder, unveiled the blockchain’s five-year roadmap at the 2026 Hong Kong Web3 Festival, emphasizing quantum security and enhanced scalability as core priorities. In his opening address titled “The Future Direction of the Ethereum Protocol,” Buterin stressed that Ethereum’s mission is not to compete on transaction speed with high-frequency platforms, but to become the world’s most secure, decentralized, and perpetually open “world computer.”
Short-term objectives include raising the gas limit to boost scalability, extending the EVM with Zero Knowledge Proofs (CKEVM), and supporting smart contract wallets and quantum-resistant signatures through computational abstraction. By 2028, Ethereum plans to reduce transaction confirmation time to between 10 and 20 seconds and introduce zkVM technology, which will allow even low-specification devices to directly verify the chain.
Quantum-resistant signature algorithms have existed for two decades but face efficiency challenges. Current quantum-resistant signatures require 2–3 kilobytes of data (compared to 64 bytes today) and cost approximately 200,000 gas on-chain (versus 3,000 currently), presenting a significant technical hurdle Ethereum must address.
