Ethereum’s Layer 2 Revolution: Top Solutions in 2025
As I dive into the world of Ethereum’s Layer 2 solutions, I’m excited to share my practical, personal, and educational experience with you. In this article, I’ll cover the top Layer 2 solutions in 2025, and how they’re revolutionizing the Ethereum ecosystem?
What is Layer 2?
Before we dive into the top solutions, let’s quickly define what Layer 2 is. Layer 2 refers to the scaling solutions built on top of Ethereum’s base layer (Layer 1). These solutions aim to increase the transaction capacity, without compromising the security and decentralization of the Ethereum network.
Why Do We Need Layer 2 Solutions?
The reason we need Layer 2 solutions is simple: Ethereum’s base layer has limitations. The network can process around 10-15 transactions per second, which is slower than traditional payment systems like Visa or Mastercard. This bottleneck has led to the development of Layer 2 solutions, which can process hundreds or even thousands of transactions per second.
