Executive Summary

Humankind is the most resilient higher life form on this planet, which stems from two main characteristics: highly adaptive and tenacious individuals who are capable of complex and abstract cooperation. Our usage of computers has added to our capabilities but has also made us more vulnerable by centralisation, creating single points of failure. As we are mirroring our societies’ high-level cooperation in computer networks, we also need to mirror our natural resilience in our software designs to take the next step forward, otherwise we will fail. This resilience needs to be woven into the fabric of all our digital interactions, from manufacturing of goods over healthcare, economic services, and public authority to social networks.

We call this design goal local-first cooperation, complementing cloud native architecture where the need for resilience outweighs the economies of scale. We derive some core principles on which such software systems are built:

Upon this basis we build more complex interactions, forming hierarchical behaviour and covering longer distances in space and time. We connect such local applications with centralised services like global blockchains or the cloud, but these connections cannot be required for local interactions that must always work.

Some further restrictions follow from the principles, most notably that we can only employ consensus (i.e. have a strongly consistent data model) when we can afford the latency and fallibility that come with it. The principles also give guidance in terms of software architecture, namely that data structures need to support evolution since we store facts for a long time, and that the flow of information is a primary design target. Finally, implementing autonomous parts is fostered by communicating events rather than state; this allows each part to independently derive and structure the information it needs.

The Plan

Our plan is to create and refine software tools that make it simple and easy to build resilient software according to the principles outlined above. This requires comprehensive documentation on the principles and how they shall be applied, and it will benefit greatly from promoting these ideas so that more people create suitable tools. We aim for a multitude of tools to grow that each cover some particular part of the problem or an application domain. By adhering to the above principles, the software that will be built on these tools will be able to cooperate on a much larger scale, between different implementations. Out of this experience may eventually emerge a set of communication standards, but we deliberately do not start from that end — we let nature run its course to find the optimal solution.

Get Involved

The endeavour outlined above is far greater than any single person or organisation who contributes. If you want to help push this forward you are very welcome to join us:
