How can a public blockchain be used for private data services? All too often this question catches out decision makers and prevents projects being deployed on public ledgers. I want to address this issue directly in this article. I will explain how personal data on a public blockchain can remain private even in a catastrophic and unlikely event that the underlying cryptosystem is broken.

公共区块链，私有数据


公有链如何用于隐私数据服务？这个问题常常困扰决策者并阻止项目部署在公共分类账上。我想在这篇文章中直接解决这个问题。我将解释即使在底层密码系统被破坏的灾难性且不太可能发生的情况下，公共区块链上的个人数据也可以保持私密性。
