API3 Core Technical Team Report, October 2021

We are happy to announce that we have released Airnode v0.2! If you have been following our reports, you should know that we have focused our efforts on Airnode since the DAO launch, but we didn’t share further details. The development of Airnode is the most critical aspect of API3 operations, as almost the entirety of our efforts — technical and non-technical — depend on the existence of this oracle node that will enable first-party oracles at scale. In this sense, we’re careful about treating Airnode development with the respect it deserves, and a part of this is preventing it from turning into an object of hype.

Airnode v0.2 is a silent release, meaning that it is public, but not necessarily publicized (this report doesn’t count because we have to tell you about it for governance purposes). What is more significant than the release itself is that we have a release management process in place, which we have tested now with great success by making this release. This will allow us to do rolling releases from here, meaning Airnode being improved iteratively (not that the pre-alpha version wasn’t good, but it had to be frozen and consequently couldn’t be improved further) and being able to address business problems by implementing new features.

I have recently posted an article on what has changed in the Airnode request–response protocol since pre-alpha. Note that a protocol update is only a subset of a node update, and this node update is especially extensive. I’ll try to list some high level items here:

The one thing that we didn’t do is a complete refactor of the node implementation, as that was already very solid in the pre-alpha version. So even though this is quite a major release, we expect the node to keep behaving stably. I’m sure there are bits that I forgot to mention, but this is where you come in anyway. You’re more than welcome to poke around and give us feedback by creating Github issues or swinging by our Discord.

All in all, this was a satisfying end to our August–October grant cycle. This was made possible by a team of great people who take pride in their work. On behalf of myself and the entire API3 community, I thank the members of the core technical team for their great effort. We’re only getting started though, so stay tuned.
