Vitalik Buterin Reorders Ethereum’s Value Stack: Bulletin Board First, Payments Second, Smart Contracts Last

Ethereum co-founder Vitalik Buterin has publicly reframed how he thinks about what the network is actually for, arguing that its most fundamental value has little to do with smart contracts or decentralized finance. The shift in framing, shared in a post following his attendance at the Real World Crypto conference, places a far more unglamorous concept at the top of the hierarchy.

Writing on X, Buterin described a thought experiment he has been working through: stepping back from the identity of being “the Ethereum community” and instead thinking of himself as a maintainer of a technical tool within a broader ecosystem of censorship-resistant, privacy-focused, and open-source technology.

Approaching the question from that angle, and spending time at a cryptography conference populated by people with aligned values but no particular attachment to blockchains, led him to a conclusion that surprised even him. The most fundamental thing Ethereum provides, Buterin argues, is what cryptographers call a public bulletin board, a globally writable and readable place where anyone can post data without permission. Smart contracts did not come first. Payments did not come first. Data availability did.

Why a Bulletin Board Matters More Than It Sounds

The term undersells the concept considerably. Buterin points out that a wide range of cryptographic protocols, including secure online voting systems, software version control, and certificate revocation mechanisms, all depend on having a neutral, tamper-resistant surface where data can be published and read by anyone. None of those use cases require computation. None of them strictly require money, though Buterin notes that permissionless anti-spam protection does require an economic layer to function. What they need at the most basic level is data availability, and Ethereum’s recent PeerDAS upgrade increased its data availability capacity by 2.3 times, with a roadmap Buterin describes as capable of going another ten to one hundred times higher.

The implication is significant. A large class of privacy and security applications that have historically been built on trusted intermediaries could, in principle, be rebuilt on Ethereum purely as an infrastructure layer, without ever touching tokens, smart contracts, or decentralized finance.

Payments Second, Smart Contracts Third

Buterin places payments second in his revised hierarchy. Many protocols need a payment mechanism to function, whether to compensate service providers, reduce spam, or enable permissionless API access without the system being overwhelmed. He singles out Ethereum combined with zero-knowledge payment channels as one of the strongest payment systems available for API use cases, and notes that ETH as an anti-sybil tool, requiring a small economic stake to participate, is a natural fit for applications that need to prevent mass account creation without resorting to phone number verification or other identity dependencies that compromise privacy.

Smart contracts come last in the ordering, though Buterin is careful to explain why they still matter enormously. Security deposits, ZK payment channel implementation, and the ability to create interoperable pointers to digital objects are all cited as meaningful smart contract use cases. He acknowledges that technically, for any use case not directly handling ETH itself, smart contracts are a convenience rather than a strict necessity. In practice, however, standardizing computation through a shared mechanism produces far more interoperability than rebuilding equivalent logic from scratch for every application.

The Perception Gap Buterin Thinks Is Holding Ethereum Back

Beyond the philosophical reframing, Buterin identifies what he sees as a practical bottleneck. The broader world, in his view, has not yet registered that Ethereum is no longer operating under the fee conditions of 2020 to 2022. Fees are now extremely low, he writes, and the scaling roadmap is designed to keep them that way even as usage grows. Infrastructure for shielding users from fee volatility has also matured considerably.

The consequence of that perception lag, Buterin suggests, is that developers and institutions evaluating Ethereum as infrastructure are still pricing in a version of the network that no longer exists. Builders who wrote off Ethereum-based solutions during periods of high congestion may not have revisited those decisions in light of what the network looks like today. Whether that gap closes through outreach, demonstrated use cases, or simply time is a question Buterin leaves open, but his broader argument is that the technical case for Ethereum as a foundational layer in privacy-preserving and censorship-resistant software stacks is stronger now than it has ever been.
