Basic Concepts Of Layer1 & Layer2 Protocols:

Layer 1

Layer 1 protocols are dependent protocols which have their own blockchains and give access for developers to build and innovate on their ecosystem. In a layman's explanation, Layer 1 can be seen as Independent protocols that allows for innovations and building.

Examples of Layer 1 projects; Ethereum, Solana, Cardano, Algorand, Avalanche, etc.

Examples of projects built on Layer 1 protocols; Uniswap, Aave, Opensea, Chainlink, etc.

Using general instances to explain, Apple Store and Google play store is an app on your mobile device where you can access any type of mobile apps and game. Linking it back to crypto, Apple Store and Google play store can be seen as perfect examples of Layer 1 protocols and the application and games that are being deployed on them are examples of projects that have been built on Layer 1 protocols.

Layer 2

Layer 2 projects can be defined as secondary protocols which are built on existing Layer 1 protocols to help solve major issues on Layer 1 protocols such as , scaling Issues, transaction speed and also helps to decrease transaction fees.

Examples of Layer 2 protocols; Optimism, Polygon, Arbitrum,etc.

Now you might be wondering how Layer 2 can help the Layer 1 protocols, I'll explain;

At this point both the layer 1 and Layer 2 protocols are integrated. While Layer 1 controls the consensus mechanism, Layer 2 now uses an external parallel network to facilitate transactions away from Layer 1. With this Layer 2 has solved the difficulties of Layer 1.

That’s it!
