At the recent Korea Blockchain Week conference, Ethereum co-founder Vitalik Buterin discussed the future of Ethereum nodes and how mobile devices could play a role in promoting decentralization and scalability.

During a talk on September 5, Buterin explained that one of the challenges facing Ethereum is the centralization of nodes, with most currently running on centralized web service providers like Amazon Web Services. He called nodes a “big piece of the puzzle” for ensuring Ethereum remains decentralized long-term.

“Stateless Clients” Mean Mobiles Could One Day Become Nodes

To solve this problem, Buterin pointed to Ethereum’s (ETH) roadmap which includes developing “stateless clients” using “Verkle Trees.” Stateless clients would significantly reduce the hardware requirements needed to run full nodes on the network, he believes.

Buterin said, “Today, it takes hundreds of gigabytes of data to run a node. With stateless clients, you can run a node on basically zero.”

Statelessness works by limiting the amount of blockchain data individual nodes need to store. Currently, full nodes must store the entire state of the Ethereum blockchain.

With statelessness, only block producers need full state data while transaction verifiers do not requi
