Ethereum co-founder Vitalik Buterin demands more independence, data protection and technical robustness if the cryptocurrency is to exist as a real alternative to cash in the future.
• Ethereum as a cash alternative
• Sweden relies more on cash again
• Butterin with wake -up call
In the midst of growing global uncertainties and technical dependencies, Ethereum co-founder Vitalik Buterin positions itself with a clear vision: The leading smart contract platform must change in order to have a digital alternative to cash, according to the expert.

Digital currencies on the crossroads?
It is clear to Butterin: If cryptocurrencies like Ethereum are to take on a social role as an alternative to cash, they must have two properties – resilience and privacy. He wrote this in a contribution to X and referred to Sweden, where the initiative for a cashless society had proven too vulnerable due to the centralized infrastructure. Because this type of dependency represents a potential gateway for government interventions, technical failures or abuse.

A digital alternative to cash?
While cash works anonymously and without a third party, the use of Ethereum and other cryptocurrencies is usually associated with centralized wallet providers, hosting services or nodes. This is in contrast to the ideal of a decentralized, globally usable means of payment.
According to Cointribute, the current transparency of public blockchains can also be seen critically. Openness promotes trust in technology, but it contradicts the privacy of users. In order to dissolve this conflict of goals, technical innovations such as zero-knowledge-proofs or anonymous transactions about layer 2 solutions are currently being researched. These should make it possible to handle payments confidentially and yet safely – similar to cash.
However, the implementation of such technologies is not unproblematic, according to Cointribute. In the past, projects such as Tornado Cash showed that data protection functions could quickly become targeted by regulatory authorities. A task that needs to be mastered if Ethereum wants to remain relevant in the long term.
In essence, however, it is now about a fundamental strategic question: Should Ethereum primarily remain a tool for Defi and Smart Contracts – or can it become a real alternative to traditional payment systems? According to the Buterin, the answer is in the further development of the network. Ethereum not only has to scale and become more efficient, but also resistant to attacks and state control – and make the protection of user data an integral part of its architecture.
