Cardano Development Update & AMA with David Esser 15th August 2019

Last week, David Esser, Cardano Product Manager at IOHK, held an AMA as part of the new series of Live Cardano development updates. He started by giving project updates, like sharing the latest on the development progress demo videos, the new version of Daedalus to Cardano achievements on GitHub and on CV VC’s Top 50 report. He then dived into questions from the Cardano community.

Project Updates

Community questions

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 Cardano team 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:

fairy_1sk6n0x2wygz224ya869jhjexzl05swn62p3gnv9jpq5f435yesr25xze2dh

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?” 26 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.

Releases

This week, the DevOps team supported the new Jormungandr build:

On Friday, Charles dropped a surprise AMA from their new offices in Longmont, Colorado, beating by a day his earlier commitment to announce some dates before the end of August. Amid the pantheon of Charles’ many AMAs since the project kicked off, it will probably go down as one of the most important. Within it, you’ll hear definitive information on the rollout of the network Shelley Rust testnet, as well as the news that real staking will be introduced in Q4 — effectively marking the beginning of the Shelley era. You’ll also hear a powerful appraisal of the Cardano project, dismantling critics with the achievements of the past several years.

Quick Video Breakdown

-The network testnet will launch in the middle of September. (Earliest Sept 15)

-The announcement of the launch of the incentivized testnet will happen on Sept 28.

-Ouroboros Hydra will be complete in September, finalizing Ouroboros research.

-There is an upcoming hackathon at the University of Wyoming on September 20th.

-The next update to Plutus will also happen in September.

-Cardano set out to solve the problems of crypto through first principles thinking.

-We’d like staking to be possible on the Yoroi wallet.

-We hope to see hosting on a small device like a raspberry pi.

-The biggest challenge of the last four years has been believing that doing the impossible was possible.

Updates on Cardano

(2:00) The rust client testnet and the networking testnet are stable after being released to the community and fixing hundreds of bugs. With the launch of Shelley we will be moving to a distributed and incentivized testnet. This will let us start to build up a community of stake pool operators and allow people to make real money through real world rewards. The network testnet will be shipping next month. At the earliest, September 15th.

(4:01) Furthermore, Charles will be traveling to Bulgaria on the 28th to celebrate the second anniversary of the launch of Byron. From there he will announce the launch of the incentivized testnet, which is essentially the roll out of Shelley.

(7:25) The big month of September

In September we are also expecting that Ouroboros Hydra will be complete. This is the final advancement in the research of the Ouroboros protocol. This is important because it is the realization of all previous research around creating a workable proof-of-stake platform. It also allows sharding as well as global scaling. The completion of Ouroboros stands to be a major step forward in solving the proof-of-stake problem in computer science.

On September 20th there will be a major hackathon at the University of Wyoming, it will be attended by 500 developers along with the governor of Wyoming. There, they will unveil the next update to Plutus. This will allow developers to build applications and smart contracts that will work on the Cardano network. The recently released Plutus book and Udemy course will help achieve parity with the Ethereum ecosystem by educating the community on building with Cardano.
