Shelley Testnet: Your weekly rollout rollup. Week Nine: W/E 23rd August 2019

Week Nine: W/E 23rd August 2019

Each week, this newsletter is where we’ll share a high-level summary of key achievements and what’s been going on in the program. 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, especially our amazing Ambassadors.

What’s up
Jormungandr was released to version 0.3.3 . This includes a major core rewrite of the internal blockchain data representation making the code safer, faster and to provide better API content. Indeed, with this new release comes a new end point for a stake pool operator to query the events schedules of the current epoch and see the past ones’ status.

Another notable change, though it is only aesthetic, is that we allow addresses to have any Bech32 prefix. For the node or the protocol, sending Ada to any of the following addresses will credit the same account:


In this case, the addresses both decompose into (output from jcli address info):

Documentation and content
Alejandro and Dorin have put together the tutorial “How to install the example Faucet App?” with more information on the Javascript SDK that is now available. The SDK is the next piece of the puzzle to make the rust node mainstream. With it, developers can use the javascript tools (node, react, etc.) they have used in the past and create good looking apps that interact with rust node. It’s worth mentioning that the javascript sdk is compiled using webassembly to have a direct link between rust and js. Check the tutorial and the code repository and give us your feedback. We are very excited to see what you are all going to build! We’ll be talking more about this nice new testnet capability in future newsletters – and some ways you can get involved – but for now, check it out and let us know what you think!
