Vitalik: Ethereum is essentially "global shared memory," with the value of public bulletin board functionality severely underestimated
Deep Tide TechFlow News, March 12 — Vitalik Buterin recently posted after attending the Real World Crypto event, reflecting on Ethereum’s core value. He stated that Ethereum’s fundamental purpose is not smart contracts or payments, but rather a cryptographic “public bulletin board” — providing an open, readable and writable data storage layer for protocols like secure voting, software version control, and certificate revocation.
Secondly, there is the payment function, with ETH serving as a natural tool against Sybil attacks; smart contracts rank third, mainly used for secure deposits, ZK payment channels, and digital object interactions. Vitalik emphasized that Ethereum is essentially a “globally shared memory.” With the PeerDAS upgrade increasing data availability by 2.3 times and significantly reducing costs, its practical application potential is still seriously underestimated by the market.
