According to Ethernodes data, most of the current 5,901 active Ethereum nodes are run through centralized network providers such as Amazon Web Services. Many experts warn that this makes Ethereum node centralized. risk of failure. Cointelegraph reported that Vitalik Buterin, co-founder of Ethereum, gave a keynote speech at the 2023 Korea Blockchain Week (KBW 2023) today, outlining six key issues to solve the centralization of Ethereum and emphasizing that the node issue is to ensure the stability of Ethereum. A major problem in maintaining decentralization of the Internet in the long term:

One of these six major problems is to make it technically easier for people to run nodes, and statelessness is one of the really important technologies to do this. Today, running a node requires hundreds of gigabytes of data. With stateless clients, it is possible to run nodes with essentially zero data.

The concept of statelessness refers to no longer relying on centralized service providers to verify network activities. According to the Ethereum Foundation, unless node operators can run on appropriate and cheap hardware, Ethereum will not be able to achieve true Decentralization is impossible.

Although stateless node state is a core part of the Ethereum roadmap, Vitalik Buterin admitted that these highly technical problems are unlikely to be solved in the near future:

These technical issues are going to have to be resolved eventually, maybe 10 years, maybe 20 years.

In addition to stateless nodes, Vitalik Buterin mentioned that the next most important measures to reduce the centralization of Ethereum include simplifying documentation, lowering the barriers to decentralized staking, ensuring that staking is safer, has a wider reach, and makes staking more convenient. And he concluded that Ethereum’s most time-critical issue is achieving a higher level of scalability. #cryptocurrency
