Due to the high gas costs involved in conducting transactions on #Ethereum, Layer 1 (L1) and Layer 2 (L2) solutions, such as Polygon, Cardano, and Solana, have become more popular.

L2 solutions are the departmental managers and executioners in charge of carrying out particular tasks, whereas L1 solutions are the organization's CEOs and top management who have greater accountability and responsibility.

However, what exactly are Layer 1 and Layer 2 solutions?

L1 solutions are the fundamental set of guidelines, or the decentralised blockchain architecture, which underpins base protocols and offers them the necessary scalability, security, and convenience.

Several techniques are used to construct this architecture, such as sharding and consensus protocols (also known as proof of work or proof of stake).

These consist of things like Solana, Ethereum, Bitcoin, and Cardano.

L2 solutions are built upon L1 solutions to increase their scalability, efficiency, and transaction speed. They fall into various categories according to their general architecture, but examples of these are Ethereum Plasma, Polygon, and the Bitcoin Lightening Network.

To put it plainly, their role is to resolve certain issues that L1 solutions encounter as network adoption and usage rise.
