Emotional about open source

Around October 2019, Nathaniel McCallum and I founded the Enarx project. Well, we’d actually started it before then, but it’s around then that the main GitHub repo starts showing up, when I look at available info. In the middle of 2021, we secured funding a for a start-up (now named Profian), and since then we’ve established a team of engineers to work on the project, which is itself part of the Confidential Computing Consortium. Enarx is completely open source, and that’s really central to the project. We want (and need) the community to get involved, try it out, improve it, and use it. And, of course, if it’s not open source, you can’t trust it, and that’s really important for security.

The journey has been hard at times, and there were times when we nearly gave up on the funding, but neither Nathaniel nor I could see ourselves working on anything else – we really, truly believe that there’s something truly special going on, and we want to bring it to the world. I’m glad (and relieved) that we persevered. Why? Because last week, on Thursday, was the day that this came true for me. The occasion was OC3, a conference in Confidential Computing organised by Edgeless Systems. I was giving a talk on Understanding trust relationships for Confidential Computing, which I was looking forward to, but Nick Vidal, Community Manager for the Enarx project, also had a session earlier on. His session was entitled From zero to hero: making Confidential Computing accessible, and wasn’t really his at all: it was taken up almost entirely by interns in the project, with a brief introduction and summing up by Nick.In his introduction, Nick explained that he’d be showing several videos recorded by the interns of demos they had recorded. These demos took the Enarx project and ran applications that the (they interns) had created within Keeps, using the WebAssembly runtime provided within Enarx. The interns and their demos were:

• TCP Echo Server (Moksh Pathak & Deepanshu Arora) – Mosksh and Deepanshu showed two demos: a ROT13 server which accepts connections, reads text from them and returns the input, ROT13ed; and a simple echo server.
• Fibonacci number generator (Jennifer Chukwu) – a simple Fibonacci number generator running in a Keep
• Machine learning with decision tree algorithm on Diabetes data set (Jennifer Kumar & Ajay Kumar) – implementation of Machine Learning, operating on a small dataset.
• Zero Knowledge Proof using Bulletproof (Shraddha Inamdar) – implementation of a Zero Knowledge Proof with verification.

What is exciting about these demos is several-fold:

1. three of them have direct real-world equivalent use cases:
   1. The ROT13 server, while simple, could be the basis for an encryption/decryptions service.
   2. the Machine Learning service is directly relevant to organisations who wish to run ML workloads in the Cloud, but need assurances that the data is confidentiality and integrity protected.
   3. the Zero Knowledge Proof demo provides an example of a primitive required for complex transaction services.
2. none of the creators of the demos knew anything about Confidential Computing until a few months ago.
3. none of the creators knew much – if anything – about WebAssembly before coming to the project.
4. none of the creators is a software engineering professional (yet!). They are all young people with an interest in the field, but little experience.

What this presentation showed me is that what we’re building with Enarx (though it’s not even finished at this point) is a framework that doesn’t require expertise to use. It’s accessible to beginners, who can easily write and deploy applications with obvious value. This is what made me emotional: Enarx is available to all, usable by all. Not just security experts. Not just Confidential Computing gurus. Everyone. We always wanted to build something that would simplify access to Confidential Computing, and that’s what we, the community, have brought to the world.

I’m really passionate about this, and I’d love to encourage you to become passionate about it, too. If you’d like to know more about Enarx, and hopefully even try it yourself, here are some ways to do just that;

• visit our website, with documentation, examples and a guide to getting started
• join our chat and then one of our stand-ups
• view the code over at GitHub (and please star the project: it encourages more people to get involved!)
• read the Enarx blog
• watch the video of the demos.

I’d like to finish this post by thanking not only the interns who created the demos, but also Nick Vidal, for the incredible (and tireless!) work he’s put into helping the interns and into growing the community. And, of course, everyone involved in the project for their efforts in getting us to where we are (and the vision to continue to the next exciting stages: subscribe to this blog for upcoming details).
