Vitalik Reviews Ethereum's True Role as Global Shared Memory

Vitalik Buterin recently shared his important perspective after participating in the Real World Crypto event, reviewing and clarifying the true role of Ethereum once again. He summarized that the market’s understanding of Ethereum’s value still does not align with reality.

From Public Ledger to Trust System

Ethereum’s most important use is not smart contracts or transfers. Instead, it is a public data platform in cryptography, providing a layer of readable and writable data accessible to various protocols across multiple fields, such as secure voting systems, software version control and management, as well as revoking and updating digital certificates. These functions rely on Ethereum’s core features: decentralization and full transparency.

Payment Function: Ethereum’s Natural Defense

The second most important function is payments, with ETH acting as a natural defense against Sybil attacks through verification mechanisms and damage control against adversaries attempting to manipulate data. This is not a minor function but a fundamental one, enabling Ethereum to maintain security as a shared memory.

Smart Contracts: Third Level but with Great Potential

Smart contracts are ranked third in importance. Despite their potential uses—such as deposits and Zero-Knowledge Proof payments—their role is still supplementary, not the system’s main mechanism.

PeerDAS and the Future of Unrecognized Potential

Vitalik’s key point is that Ethereum, at its core, is a “global shared memory” system designed to store and share data securely and transparently. With the upgrade to PeerDAS, which increases data availability by 2.3 times and significantly reduces transaction fees, the system’s practical potential remains undervalued by the market. This upgrade could change how Ethereum is used in the near future.
