Vitalik: The core value of Ethereum is a globally shared "bulletin board," with smart contracts and payments being just additional features Odaily Planet Daily News: Vitalik Buterin stated in an article on the X platform that the fundamental value of Ethereum is not smart contracts or payment functions, but as a "bulletin board" that can be publicly written and read, providing data availability support for encryption protocols. He pointed out that many cryptographic protocols, including secure online voting, software version control, certificate revocation, etc., require a public data space, and Ethereum's upgraded PeerDAS mechanism can increase data availability by 2.3 times and has the potential to increase it by another 10 to 100 times. Buterin also emphasized the role of ETH in payments, resistance to Sybil attacks, and secure deposits for smart contracts, making it a core component of a decentralized, private, and secure open-source technology stack. He believes that Ethereum can be seen as a 'global shared memory', and its low cost and scalability improvements will further drive its application implementation, including DeFi and more potential scenarios.
