At the Korea Blockchain Week conference, Vitalik Buterin, the co-founder of Ethereum, discussed the ongoing issues with centralization inside the Ethereum network in a provocative way. Nodes are important, stressed Buterin, and are a “big piece of the puzzle” in preserving Ethereum’s long-term decentralization.
One of the core challenges facing Ethereum is the centralization of nodes, with a majority currently relying on centralized web service providers such as Amazon Web Services (AWS). Buterin stressed the importance of addressing this issue to preserve Ethereum’s decentralization principles.
To tackle this centralization problem, Buterin pointed to Ethereum’s roadmap, which includes the development of “stateless clients” using “Verkle Trees.” Stateless clients have the potential to drastically reduce the hardware requirements necessary to run full nodes on the Ethereum network.
Buterin explained, “Today, it takes hundreds of gigabytes of data to run a node. With stateless clients, you can run a node on basically zero.” Stateless clients operate by limiting the amount of blockchain data individual nodes must store, with only block producers requiring full state data.
The groundbreaking concept introduced by Buterin is that stateless clients could pave the way for mobile devices to become Ethereum nodes. While this vision may not be realized in the near future, it holds the promise of democratizing Ethereum’s infrastructure by enabling individual users worldwide to easily and affordably run nodes on consumer hardware like mobile phones.

However, Buterin cautioned that there are still technical hurdles to overcome, and he estimated that it could take between 10 to 20 years before statelessness is fully implemented on Ethereum.
Despite the long-term vision of statelessness, Buterin reiterated that the immediate focus is on scalability solutions. Innovations like zero-knowledge rollups are being explored as near-term strategies to enhance Ethereum’s scalability. Statelessness, in the long run, offers a pathway to scalability by allowing more lightweight nodes to participate in consensus and transaction validation.
The discussion about mobile nodes and stateless clients builds upon the buzz around account abstraction earlier this year. Ethereum’s ERC-4337 upgrade aims to simplify the user experience by introducing features like logging in with emails or phone numbers, wallet recovery, spending limits, and session keys for dApps. This upgrade aligns Ethereum with a more user-friendly Web3 experience, resembling Web2.
Furthermore, the Ethereum community has proposed an innovative solution to enhance the security of decentralized finance (DeFi) protocols. Enter ERC 7265, a revolutionary protocol that addresses the challenges and risks associated with DeFi by introducing a fail-safe mechanism built into the smart contracts of DeFi protocols. This groundbreaking proposal seeks to transform the way DeFi platforms handle potential hacks and protect user funds.
In a separate Twitter Space conversation, Buterin applauded developments in the broader cryptocurrency ecosystem, highlighting the significance of scalability improvements and praising innovations like Ordinals and the BRC-20 token standard. He emphasized the importance of moving beyond stagnation and fostering a culture of progress in the cryptocurrency space.
Vitalik Buterin’s vision for Ethereum includes addressing node centralization through stateless clients, potentially opening the door for mobile devices to play a role in the network’s decentralization and scalability. While technical challenges remain, Ethereum continues to innovate and adapt to meet the evolving needs of the crypto community.
