Vitalik Buterin highlighted the importance of Ethereum’s resilience and independence during his speech at the 4th Hong Kong Web3 Festival on April 20, 2026. Addressing the audience, Buterin emphasized that the network must maintain its functionality and security even if key developers choose to step away in the future. He described this as a crucial test for any blockchain system with long-term ambitions and stressed that Ethereum is designed with these principles in mind.
Ethereum and the “walkaway test”
Buterin introduced the concept of the “walkaway test,” which asks whether Ethereum could continue operating effectively if its core development team retired or left the project. He argued that blockchains should not remain dependent on a small group of engineers or leaders and pointed to Bitcoin as an example of a system that manages to run without ongoing intervention from its original creators.
The goal is to ensure that Ethereum, like Bitcoin, becomes robust and self-sustaining, relying on public rules, shared development tools, and support from its larger community. According to Buterin, such decentralization forms the foundation of trust and longevity for any valuable blockchain platform.
Vitalik Buterin is a co-founder of Ethereum, the world’s second-largest blockchain platform by market capitalization. He is recognized for his significant contributions to the development of decentralized applications and blockchain protocols and remains a leading voice in industry discussions about security, scalability, and future trends.
Technical focus: Formal verification and quantum resistance
Looking ahead, Buterin outlined several technical priorities for Ethereum’s continued stability. He revealed that formal verification—a method that uses rigorous mathematical proofs to check the correctness of code—is gaining momentum in Ethereum development, assisted by artificial intelligence tools. This approach aims to minimize software flaws and fortify the network as a long-term digital asset infrastructure.
Buterin also addressed the need for quantum resistance, referencing anticipatory measures to protect the network against the future risks posed by quantum computing. Although practical quantum computers have not yet emerged, research into safeguarding blockchains from potential threats is ongoing and forms part of Ethereum’s broader roadmap.
Ethereum is “meant to be the secure chain, the decentralized chain, the chain you can rely on,” Buterin stated, reinforcing the project’s commitment to security rather than transaction speed.
Not competing for speed
Buterin made clear that Ethereum does not aim to compete with high-frequency trading platforms or become the fastest chain in the industry. He emphasized that the network’s core values center on safety, decentralization, and reliability, instead of prioritizing raw speed.
Many competing blockchain projects focus on instant transactions as a selling point. However, Buterin’s remarks signaled a different strategy for Ethereum: supporting complex digital assets and smart contracts with a stable infrastructure.
As the main platform for a diverse range of on-chain services, including DeFi and tokenization, Ethereum’s reputation rests on maintaining dependable operations. Ensuring continuity, even in the absence of core developers, remains at the heart of its long-term agenda.
