For years, Ethereum has often been described as a “global computer,” capable of supporting everything from DeFi to NFTs and complex decentralized applications. However, recently, Vitalik Buterin предложил a different perspective—one that is simpler, yet arguably more fundamental.
Instead of forcing blockchain into every possible use case, he suggests Ethereum should be viewed as a decentralized public bulletin board—a place where data can be posted, verified, and accessed transparently.
This raises an important question: is the crypto industry over-engineering its own technology?

Blockchain is not a solution for everything
One of Buterin’s key arguments is that many developers start with blockchain and then try to find problems to fit it into.
This approach often leads to unnecessary complexity, higher costs, and systems that don’t deliver meaningful improvements.
Instead, he proposes the reverse:
start with the problem, and only use blockchain where it is truly needed.
From this perspective, Ethereum’s value lies not in replacing every system, but in providing a trusted infrastructure layer for applications that require transparency and censorship resistance.

Ethereum as global shared memory
The concept of a “public bulletin board” is well known in cryptography. Many secure systems require a place where data can be publicly posted and verified.
Examples include:
electronic voting systems
certificate revocation lists
cryptographic protocol records
Ethereum can fulfill this role because it allows:
anyone to publish data
anyone to verify it
without relying on a central authority
In this sense, Ethereum can be understood as a global shared memory layer.
The role of ETH and smart contracts
Even within this simplified model, ETH and smart contracts remain essential.
ETH introduces an economic cost that prevents spam. Without such a mechanism, open systems could easily be abused.
Smart contracts can be used for:
managing deposits
automating agreements
coordinating interactions between participants
Additionally, technologies like zero-knowledge payments may enable small, private transactions.
PeerDAS and data scalability
Upgrades such as PeerDAS are making this vision more practical by increasing Ethereum’s data capacity.
This reflects a broader shift: Ethereum is not just a platform for financial transactions, but also a system for storing and distributing reliable data.
Conclusion
Buterin’s perspective serves as a reminder that not all problems require complex solutions.
In many cases, blockchain’s greatest value may lie in simple but foundational functions—such as providing a reliable place to store and verify data.
If widely adopted, this approach could position Ethereum not just as a programmable platform, but as a core infrastructure layer of the decentralized internet. $XRP
