Ethereum’s Biggest Role Is a Public Bulletin Board, Says Vitalik Buterin

Vitalik Buterin recently argued that the most important function of Ethereum is not smart contracts or payments but acting as a censorship-resistant public bulletin board.

According to his explanation, many cryptographic systems including secure voting, certificate revocation and software version verification require a publicly readable and writable space where data can be stored and verified. Ethereum’s role in this case is to provide reliable data availability rather than complex computation.

Buterin noted that recent upgrades such as PeerDAS have significantly increased the network’s data availability capacity, expanding its potential use across cryptographic applications.

Payments as the Second Key Function

Payments represent the second major role for Ethereum. Digital payments can act as a built-in anti-spam mechanism for permissionless services, particularly for APIs and decentralized applications.

Buterin highlighted that Ethereum combined with zero knowledge payment channels can support efficient systems where users pay small fees to access services while maintaining privacy and security.

Smart Contracts Enable Broader Applications

Smart contracts come third in importance, serving mainly as programmable tools that enable deposits, automated rules and decentralized financial applications. These functions allow developers to build complex systems while relying on Ethereum as shared global infrastructure.
