(May 31, 2022) Amazon AWS has posted a video interview on its Youtube channel and social media, "ArcBlock: Leveraging Amazon QLDB to Build a Decentralized Identity Solution " (https://www.youtube.com/watch?v=o6DZRwe30Ls), an edited version of a conversation between Amazon Architect Don Simpson and ArcBlock CEO Robert Mao at the 2021 AWS Reinvent event.

This video is also included in Amazon's AWS Architecture Center (https://aws.amazon.com/architecture/ ).

We wrote an engineering blog about the technical details behind the video, which was published on our own website last year (https://www.arcblock.io/blog/en/post/2021/12/02/arcblock-did-aws-qldb), and this article is planned to be published on the AWS Blog as well.
