Vitalik Buterin emphasized on X platform that Ethereum's value lies in its role as a publicly readable and writable "bulletin board" supporting data availability for cryptographic protocols. He pointed out that Ethereum's upgraded PeerDAS mechanism can significantly enhance data availability, and believes that ETH's functions across multiple domains make it central to decentralized technology.

Odaily Planet Daily reports that Vitalik Buterin posted on X stating 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, and certificate revocation—require a public data space. Ethereum’s upgraded PeerDAS mechanism can increase data availability by 2.3 times and has the potential to improve it by another 10 to 100 times. Buterin also emphasized that ETH’s role in payments, resistance to Sybil attacks, and secure deposits for smart contracts makes it a core component of a decentralized, private, and secure open-source technology stack. He believes Ethereum can be viewed as a “global shared memory,” and that lower costs and scalability improvements will further promote its practical applications, including DeFi and many other potential scenarios.
