自2018年5月生效以来，欧盟通用数据保护条例(GDPR)在公共(未经许可)区块链系统的用户中引发了严重担忧。这种担忧是由公共区块链系统的一些独特特征与GDPR中引入的一些新的数据主体权利之间的紧张关系引发的，例如数据不变性和“擦除权”(又名“被遗忘权”)。这项工作的目的是了解公共区块链系统背后的服务提供商和开发者如何向用户沟通此类GDPR相关挑战，以及用户如何感知此类GDPR相关问题。为此，针对对应加密货币资本市场规模超过1.5亿美元的50个公共区块链系统，我们分析了以下三个在线渠道上的相关沟通和讨论：博客和论坛帖子、GitHub存储库和Twitter上的讨论。我们的结果显示，所选公共区块链系统的服务提供商和开发商在Twitter上与GDPR相关的在线讨论中没有发挥积极作用。他们也没有经常在他们的论坛和博客上与他们的用户就GDPR进行交流，在我们研究的17,821篇帖子中，我们只能找到56篇。我们的研究还显示，在所研究的系统中，只有极少数(4)在其GitHub存储库中提到了GDPR。我们的工作为公共区块链部门在公共区块链系统具有挑战性的GDPR合规问题上缺乏透明度和积极沟通提供了新的证据。
Since coming into effect in May 2018, the EU General Data Protection Regulation (GDPR) has raised serious concerns among users of public (permissionless) blockchain systems. Such concerns are triggered by a tension between some unique characteristics of public blockchain systems and some new data subject rights introduced in the GDPR, e.g., the data immutability and the “right to erasure” (a.k.a. “the right to be forgotten”). The aim of this work is to understand how service providers and developers behind public blockchain systems have communicated about such GDPR-related challenges to their users and how the users have perceived such GDPR-related issues. To this end, for 50 public blockchain systems whose corresponding cryptocurrency had a capital market size over $150 million, we analyzed relevant communications and discussions on the following three online channels: blog and forums posts, GitHub repositories, and discussions on Twitter. Our results show that service providers and developers of the selected public blockchain systems did not play an active role in GDPR-related online discussions on Twitter. They also did not communicate with their users about GDPR on their forums and blogs frequently, where we could identify only 56 posts out of 17,821 posts for the period we studied. Our study also reveals that only an extreme minority of the studied systems (4) mentioned GDPR in their GitHub repositories. Our work adds new evidence on the lack of transparency and active communications of the public blockchain sector on the challenging GDPR compliance issue of public blockchain systems.
