Nuts specifications


Dear reader. This page contains the Nuts specification documents in the form of a Request For Comments (RFC). These specifications address several subjects which together can be used to build a piece of software which is capable of interacting with the Nuts network.

Who is this page for?

The RFCs are written with a technical audience in mind but we aim to keep the introduction sections readable for a broader audience. One might find the RFCs interesting when designing new healthcare exchange scenarios, connecting software to the Nuts network and wanting to know more about how a decentralised network like Nuts works.

How to comment on the RFCs

The idea of these RFC is to invite people to comment. If you think there are improvements to make, you can open an issue on the GitHub repository or contact the community on Slack in the #specification channel.


The specification builds on existing standards. The diagram below shows how the RFCs relate to each other.
