A MarsBit article takes a critical view of the long-debated “blockchain trilemma.” The article argues that the industry’s focus on the trade-off among decentralization, scalability and security does not identify the most fundamental barrier. Instead, it describes the trilemma framework as a false problem and shifts attention to two weaknesses that affect public blockchain adoption: legitimacy and privacy.
Regulatory Uncertainty and Full Transparency
According to the article, the permissionless nature of public chains creates regulatory uncertainty, which becomes a compliance barrier for institutional capital and mainstream financial applications seeking to move on-chain. At the same time, the full transparency of public chains exposes users’ financial data and gives rise to hidden costs such as MEV. In the article’s view, these issues place more direct limits on the expansion of blockchain applications than a narrow debate over performance, security and decentralization.
The article argues for cryptographic upgrades built around “privacy by default + provable compliance.” Under that approach, users’ financial data would no longer be exposed by default, while compliance status could still be verified. The article presents this as a path for institutional capital and mainstream financial applications to enter the public-chain environment in a safer way.
