Vitalik: The core value of Ethereum is a globally shared "bulletin board," with smart contracts and payments being merely additional features

Ethereum co-founder Vitalik Buterin posted on the X platform that the fundamental value of Ethereum is not its smart contracts or payment functions, but rather as a publicly writable and readable "bulletin board" that provides data availability support for cryptographic protocols.

He pointed out that many cryptographic protocols—including secure online voting, software version control, certificate revocation, and more—require a public data space, and the upgraded PeerDAS mechanism in Ethereum can increase data availability by 2.3 times, with the potential for further increases of 10 to 100 times.

Buterin also emphasized the role of ETH in payments, resistance to Sybil attacks, and security deposits for smart contracts, making it a core component of a decentralized, private, and secure open-source tech stack.

He believes that Ethereum can be seen as a "global shared memory," and improvements in low fees and scalability will further drive its application in various scenarios, including DeFi and more potential use cases.
