With the increasing congestion on the Bitcoin network and rising transaction fees, Layer-2 networks have emerged as a revolutionary solution to improve efficiency and expand the capabilities of the original chain. What do these networks mean? And why are they considered one of the most important trends in 2025? Let's discover that together 👇
🧩 What are Bitcoin Layer-2 networks?
Layer-2 networks are solutions built on top of the main Bitcoin chain (Layer 1), aiming to accelerate transactions, reduce fees, and expand usage without affecting the security of the underlying network.
⚙️ How do Layer-2 networks work?
These networks conduct transactions off the main chain and then record the final results later on the main blockchain, reducing the pressure on the original network.
This allows for the execution of thousands of operations quickly and efficiently while maintaining the security of the core Bitcoin.
🌟 What are the benefits of Layer-2?
