Kadena Tech Bulletin #5


August 31, 2023

Welcome to the 5th issue of The Kadena Tech Bulletin!

Whether you are already familiar with Kadena or just learning about it for the first time, the Kadena Tech Bulletin provides a short technical overview of how we are revolutionizing the blockchain industry, one block at a time. From Pact to Chainweb, to how we are refining our builder onboarding process, we will provide our community of builders and developers with all the updates and tools needed to help nurture and scale their projects in our ever-growing ecosystem.

Here’s a recap of the last month:


After a long wait, you can now store your KDA tokens on Ledger! We are very proud of the team at Kadena and the community for making this happen.

Read this article by Ledger Docs for a step-by-step guide to setting up your Ledger Kadena (KDA) account and transferring your KDA tokens to a Ledger device.

2. Pact 4.8

We’re excited to announce the release of Pact v 4.8!

This release brings a range of improvements, including bug fixes, updates to formal verification, and internal changes that enhance the platform’s performance, stability, and functionality.

3. Chainweb Stream

Last month, we released the initial experimental version of Chainweb-stream Server and Client. This new system enables the continuous streaming of transactions, simplifying the process for projects to run their applications on Kadena’s blockchain.

The Chainweb-stream-server functions as a “middleware” server, handling all polling tasks on your behalf and exposing streams of transactions to clients. Its counterpart, the Chainweb-stream-client, complements the server by offering a consistent experience across different browsers and environments.

Kadena’s Developer Experience team is thrilled to announce the launch of the alpha version of “@kadena/client,” which enables JavaScript/TypeScript users to easily interact with the Kadena blockchain.

Moreover, @kadena/client also features a functional approach through “@kadena/client/fp,” providing builders more flexibility in creating commands, such as composing “command” or “lazy loading.”
