数字身份尚未得到解决：经过多年的研究，互联网上仍然没有可信的通信。为了在互不信任的背景下提供身份，本文提出了一种基于区块链的数字身份解决方案。在不依赖于单个可信第三方的情况下，所提出的解决方案实现了护照级别的合法有效身份。这种使身份具有自我主权的解决方案建立在一个通用的可证明声明模型之上，需要收集来自第三方的真实性证明。然后，索赔模型被证明是区块链结构和证明方法不可知的。支持这两个索赔模型属性的四种不同实现为索赔创建和索赔验证提供了亚秒级的性能。通过自我主权身份，合法有效的地位和可接受的性能的属性，我们的解决方案被认为是适合于一般公众采用。
Digital identity is unsolved: after many years of research there is still no trusted communication over the Internet. To provide identity within the context of mutual distrust, this paper presents a blockchain-based digital identity solution. Without depending upon a single trusted third party, the proposed solution achieves passport-level legally valid identity. This solution for making identities Self-Sovereign, builds on a generic provable claim model for which attestations of truth from third parties need to be collected. The claim model is then shown to be both blockchain structure and proof method agnostic. Four different implementations in support of these two claim model properties are shown to offer sub-second performance for claim creation and claim verification. Through the properties of Self-Sovereign Identity, legally valid status and acceptable performance, our solution is considered to be fit for adoption by the general public.
