Evolution of the Lisk SDK through major versions

A review of the Lisk SDK's development timeline highlights key feature introductions like dynamic fees, a new consensus protocol, and embedded databases.

#4about 2 minutes

Understanding the three core Lisk architectures

The Lisk SDK is built on three core architectural principles: a flexible on-chain architecture, an integrable off-chain architecture, and an open communication architecture.

#5about 4 minutes

Building custom logic with the on-chain architecture

The on-chain architecture uses Lisk modules to define custom data structures, control blockchain lifecycle hooks, and create interfaces for inter-module communication.

#6about 4 minutes

Integrating external services with off-chain plugins

The off-chain architecture uses plugins for external integrations and non-consensus tasks, communicating with the application via an open IPC socket.

#7about 5 minutes

Exploring blockchain use cases and introducing NFTs

Lisk is suitable for a wide range of use cases like digital identity and FinTech, with Non-Fungible Tokens (NFTs) being a prime example of a custom application.

#8about 4 minutes

Defining the NFT application requirements

The NFT demo application's requirements are mapped to core Lisk SDK concepts, including modules for on-chain logic, plugins for external access, and transactions for state changes.

#9about 5 minutes

Setting up a new Lisk application from scratch

A new blockchain application can be initialized and run with just a few lines of JavaScript by using the default application configuration from the Lisk SDK.

#10about 7 minutes

Implementing the NFT module and transaction logic

A code walkthrough demonstrates how to define a custom NFT module, extend the account schema, and implement the `apply` logic for creating and purchasing NFT assets.
