论文摘要
长期以来，以安全且尊重隐私的方式建立和验证通过互联网验证人类身份的挑战。在本文中，我们探讨了在信任注册表的上下文中探索可扩展性，安全性和权力下放的区块链三元素：对于分散的身份方案的信任根源，该方案可以启用对共享记录的读写访问，并且具有篡改。我们对Hyperledger Indy进行了一个案例研究 - 一种开源技术定制了分散身份 - 并进行了两个经验实验，以衡量亚马逊Web服务自然主义环境中超过45,000笔交易的潜伏期。我们得出的结论是，信托注册表的可伸缩性问题具有多个方面。尽管Hyperledger Indy捕获了对支持分散身份方案的数据有用的数据，但其可伸缩性限制的连锁效应确实可能对安全性和分散性的属性产生限制。当前的凭证验证过程依赖于用交易处理瓶颈的分类帐的交易处理，这可能会限制非替代的理想。
The challenge to establish and verify human identity over the Internet in a secure and privacy-respecting way is long-standing. In this paper, we explore the blockchain trilemma of scalability, security, and decentralization in the context of the Trust Registry: a root of trust for a decentralized identity scheme that enables read and write access to shared records and is tamper-resistant. We make a case study of Hyperledger Indy -- an open-source technology bespoke for decentralized identity -- and conduct two empirical experiments to measure the latency of more than 45,000 transactions in the naturalistic environment of Amazon Web Services. We conclude that issues of Trust Registry scalability have multiple facets. While Hyperledger Indy captures data useful to underpin a decentralized identity scheme, the knock-on effect of its scalability limitations may indeed place constraints on properties of security and decentralization. The current credential verification process relies on transaction processing by a ledger with transaction processing bottlenecks, which may constrain the ideal of non-repudiation.
