Recap: IOHK Monthly Cardano Development Updates - 28/05/2020

(written by @Eric_Czuleger)

On May 28th 2020 Tim Harrison, sat down with product director for Cardano Aparna Jue to discuss the latest developments in the roll out of the Haskell Shelley testnets. They are joined by Haskell engineer Kevin Hammond to gain some insight into how the initial pioneer phase has gone and what the future holds for the testnets. Hyperlinks and timecodes in relation to key questions have been placed at the bottom of the document for your convenience.

Mounting integrations

There has been a great deal of development in separate workstreams, but this particular update will focus on the roll out of Shelley. There is a virtual summit forthcoming and we will be discussing other key pillars like tokens, digital IDs, and Daedalus in future updates. For now, it is important to give a high level update of what has been happening recently.

We are on track for hardware integration of Daedalus with ledger. That comes from our partner Vacuum Labs. This will be covered in a video from Darko. The Goguen workstream is also progressing nicely. In all of our current endeavors, IOHK is building to specification while keeping the user community in mind.

When building we are asking questions about ease of use, competition, cost, and investigating every possible area to consider. There is also deeper research, scope, and functionality which we are attempting to gather testing and feedback on. Our production and delivery roadmaps will begin to look similar in this build-test-iterate model. The ‘friends and family testnet’ is one example of this.

Team dedication

In terms of our people we began having dedicated teams working towards the same goal posts. This initial Haskell Shelley testnet began with the so-called pioneers. This was focused around user acceptance testing. This is important to building relevant products. Flight was an example of building something that allowed us to collect organized feedback. While research is great, testing in real world circumstances with real users is vital.

The ITN was a good example of this kind of testing. Stakepool operators needed to interact with the ITN as if they were beginning a real business. We therefore invited those individuals over to become pioneers on the Haskell Shelley testnet. This has been abundantly successful. We have had 168 connections to the testnet. 90 percent of expected blocks are being produced. We had 2 bugs in the last few days and we understand that the velocity in development is going quite well. Needless to say we are excited about where the Haskell Shelley testnets are taking us.

followed by a ~ ( ^15% ) on the news

i have expectation management concerns ¯_(ツ)_/¯

given that this was supposed to have happened by march (according the roadmap) does anyone else, have doubts that the 2020 deadline to have delivered Voltaire and Goguen will be met?

finally I see exact days, I hope everything will be done in time and it will be interesting to watch what will happen in August

Goguen, yes (hope so anyway), it is parallel developed with Shelley.
Voltaire, no don’t think so. But we will see, no hurry, make it right the first time.


I would say that release dates for Goguen and Voltaire would be speculation at this point. Why? Because development for those projects (at least for Goguen) has been going on for quite some time. Integration of those to Cardano network depends on how modular everything is. They’ve been saying that it’s pretty modular. So, my speculation based on those facts is: I don’t see why we could not see Goguen this year and Voltaire at the end of the year or maybe 1st quarter of the next year.
