Architecture Decision Record (ADR) Process

This is a location to record all high-level architecture decisions for identity features and functionality on cheqd network.

Architecture Decision Records directly linked to on-ledger functionality is documented separately on the cheqd ledger/node documentation site.

An Architectural Decision (AD) is a software design choice that addresses a functional or non-functional requirement that is architecturally significant.

An Architectural Decision Record (ADR) captures a single AD, such as often done when writing personal notes or meeting minutes; the collection of ADRs created and maintained in a project constitute its decision log.


ADRs are intended to be the primary mechanism for proposing new feature designs and new processes, for collecting community input on an issue, and for documenting the design decisions. An ADR should provide:

  • Context on the relevant goals and the current state

  • Proposed changes to achieve the goals

  • Summary of pros and cons

  • References

Note the distinction between an ADR and a spec. The ADR provides the context, intuition, reasoning, and justification for a change in architecture, or for the architecture of something new. The spec is much more compressed and streamlined summary of everything as it stands today.

If recorded decisions turned out to be lacking, convene a discussion, record the new decisions here, and then modify the code to match.

Creating new ADR

Use the ADR template when creating a new ADR.
