Blockchain Community Group

The mission of the the Blockchain Community Group is to generate message format standards of Blockchain based on ISO20022 and to generate guidelines for usage of storage including torrent, public blockchain, private blockchain, side chain and CDN. This group will study and evaluate new technologies related to blockchain, and use cases such as interbank communications.

Note: Community Groups are proposed and run by the community. Although W3C hosts these conversations, the groups do not necessarily represent the views of the W3C Membership or staff.
