Chainpoint Community Group

The mission of this group is to establish a standard for creating a universally verifiable proof of any data, file, or series of events, by anchoring data to the blockchain and other sources. This allows anyone to prove the data existed at a point in time and has not been modified.

The group will publish and formalize the Chainpoint specification as a stable reference, maintain a test suite, and take feedback and use cases for the future evolution for the specification.

The Chainpoint Community Group will coordinate with the Blockchain Community Group for general standardization of blockchain-related technology, and will operate according to the Chainpoint CG charter. You can read more about Chainpoint, its history, and goals, on our recent blog post announcing Chainpoint 2.0.

This group invites participants who are actively developing and deploying proof-of-existence, timestamping, and data integrity solutions, who are skilled in blockchain technologies, and who can work on use cases for Chainpoint and related technologies.

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.

This is a community initiative. This group was originally proposed on 2016-09-13 by Wayne Vaughan. The following people supported its creation: Wayne Vaughan, Doug Schepers, Jason Bukowski, Tom Kysar, Manu Sporny. W3C’s hosting of this group does not imply endorsement of the activities.

The group must now choose a chair. Read more about how to get started in a new group and good practice for running a group.

We invite you to share news of this new group in social media and other channels.
