L2 Networks and Rollups

In this chapter, we will look into various topics related to scaling solutions in the blockchain ecosystem. We will start with the concept of Layer 2 networks, which provide scalability by proceeding with transactions off-chain while maintaining the security and privacy of the blockchain. We will also explore different types of Layer 2 networks, including optimistic rollup, ZK rollup, and side chains at a very high level.

This is again an advanced topic and we will be covering only an introduction to L2 and rollups.

In this chapter, we’re going to cover the following main topics:

  • Understanding L2 networks
  • Understanding how Polygon works (Matic)
  • Understanding rollups
