According to TechFlow news, on March 12, Vitalik Buterin recently posted an article after participating in the Real World Crypto event, rethinking the core values of Ethereum. He said that Ethereum's most fundamental use is not smart contracts or payments, but a "public bulletin board" in the cryptographic sense - providing a publicly readable and writable data storage layer for protocols such as secure voting, software version control, and certificate revocation.

secondly, the payment function, ETH can be used as a natural tool to prevent 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 "global shared memory," and its real-world application potential is still severely underestimated by the market as the PeerDAS upgrade increases data availability by 2.3x and fees are significantly reduced.
