The presentation will introduce the Lisk SDK and how it is used to build blockchain applications. We will give an in-depth explanation of the new Lisk SDK Architecture and the three ways to build, extend, and interact with a blockchain application built with the Lisk SDK. Therefore, the talk will cover aspects such as extending the distributed ledger-based on your business requirement, providing extended APIs for external third-party apps, or scripting some utilities to interact with blockchain application on the command line.
