Shelley Testnet: Your weekly rollout rollup. Week Four: W/E 19th July 2019

Week Four: W/E 19th July 2019

Each week, this rollup is where we’ll share a high-level summary of key achievements and what’s been going on. Remember, for the very latest technical updates you can follow all the commits and pull requests in the community GitHub.

If you are not already part of the conversation, you’ll find a hive of activity over at the stake pool Best Practice Telegram. With over 2,200 members and loads of engaged users, this is a great resource for anyone interested in contributing to the program. Continued thanks to everyone from the community, including our Ambassadors, for supporting the progress of the testnet.

So here we have it, our four-weeks-in rollup, sharing the latest activity in the testnet rollout program.

Some notable points to report from the dev side:

  • Working with to get our Chocolatey package out of moderation.
  • Jormungandr version 0.3.1 pushed for release.
  • Jormungandr-nix has been updated and snappy/homebrew packages have been bumped to 0.3.0.

Support updates

In total, during this testnet we have had 27 tickets: 4 were important bugs which have been fixed, 8 were documentation improvements and the rest were questions.

This week, we have closed the last bug reported by the community:

  • Transaction ID identical when sending same amount twice #14: This defect occurred when creating transactions with accounts (not UTXOs), whereby duplicated IDs were created and the second transaction couldn’t go through.
  • Also clarified other support questions (#30 and #31): these helped us make nice improvements to error messages in Jormungandr.

Please keep your feedback coming as it helps the testnet’s progress!

Documentation and Guides

  • Charles gave an update on what’s happening in the world of Cardano (including the latest on the testnet) before heading off on a short summer break. Lots of good info, so check it out here.
  • ICYMI - there’s a handy Staking FAQ page you can find right here.

Community content

We’ve continued to see lots of folks download the self node and get it up and running on a variety of different systems. Since we kicked off the program a little over one month ago, we have seen numerous posts across Reddit, Telegram and the Cardano forum talking about how people have found the set up straightforward, quick and painless. Thanks for the support. Because of you, we’re able to keep on making it easier for new users and with each new release!


The Stakepool Testing team are working hard on features relating to networking and delegation, which are not yet completed and will continue into next week. We will be providing a release this week that will provide additional REST calls for node shutdown (control API) and get blockchain settings/parameters.

Next week (July 22nd-26th)

This newsletter will be taking a week’s vacation next week. So expect to see a new rollup a fortnight from now, packed full of fresh goodness!

But don’t worry, the testnet work will continue unabated. Planned work includes…

  • Networking capability
  • Javascript SDK

See you in two weeks!

“4 were important bugs which have been fixed”

This one is still there ;

Hi @regisg. That counting is referring to issues raised by community members here -

The bug you are referring to is tracked inside the project development repo and the development team is actively looking and prioritizing those too.

Thanks for your reply. I was not worrying : I have great confidence on IOHK’s team. It’s a bit frustrating to see the node halting without error message while submitting transactions… kind of Coitus interruptus.
