Vitalik: The core value of Ethereum is the "public bulletin board"

PANews reported on March 12 that Vitalik Buterin recently published an article stating that the core use of Ethereum is not smart contracts or payments, but serving as a "public bulletin board" that provides a publicly readable and writable data availability layer for cryptographic protocols such as voting, certificate revocation, and version control. He also mentioned that ETH can be used as an anti-sybil payment tool, while smart contracts act as a shared programming layer and deposit execution tool.
