ChainThink reports that on March 12, Ethereum founder Vitalik posted that he recently attended Real World Crypto and its related events, which gave him a clearer understanding of blockchain's applications. Where can Ethereum create the greatest value? The answer that emerged first from these events was not what you might expect—it’s neither smart contracts nor payments, but rather what cryptographers call a “public bulletin board.”
Ethereum holds significant value, and if you step back and view it from first principles—simply as a technological tool: a globally shared memory—you can understand its worth. I believe a major bottleneck limiting further expansion of this use case is that the world hasn’t yet realized we are no longer in the 2020–2022 phase. Today, transaction fees are extremely low, and we have a stronger scaling roadmap to ensure fees remain low even if usage surges dramatically. The infrastructure has also matured in its ability to shield users from fee volatility.
Viewing Ethereum blobs as a bulletin board, ETH as an asset and universal payment backup, and Ethereum smart contracts as a shared programming layer fully aligns with the principles of a decentralized, private, and secure open-source software stack. However, we should continue improving the Ethereum protocol and infrastructure to ensure it operates efficiently in all these scenarios.
