TechFlow News: On March 12, Vitalik Buterin recently posted after attending the Real World Crypto event, rethinking Ethereum’s core value proposition. He stated that Ethereum’s most fundamental use case is not smart contracts or payments, but rather a cryptography-based “public bulletin board”—a publicly readable and writable data storage layer enabling secure voting, software version control, certificate revocation, and similar protocols.
Payments come second: ETH serves as a natural anti-Sybil tool; smart contracts rank third, primarily supporting secure deposits, ZK payment channels, and digital object interactions. Vitalik emphasized that Ethereum is, at its core, a “globally shared memory.” With the PeerDAS upgrade boosting data availability by 2.3× and significantly lowering fees, its practical application potential remains severely underestimated by the market.
