What Are The Differences Between Layer 1 and Layer 2 Blockchain Explained:

i- Layer 1 Blockchain refers to the main Blockchain for example Ethereum Blockchain, Bitcoin Blockchain, Solana Blockchain, Polkadot Blockchain etc.


ii- Layer 2 Blockchain are built on top of the Layer 1 Blockchain security infrastructure usually to help scale the number of transactions that can be handled by Layer 1 Blockchain
and also comes with other benefits like cheaper transaction fees and dedicated


iii- Example of Layer 2 Blockchains For Ethereum Blockchain are Metis, Polygon etc



iv- Layer 2 Blockchain also makes it possible to have dedicated chains for specific use cases beyond general use-cases focus by their Layer 1 Blockchain
     - like Immutable X layer 2 Blockchain on Ethereum dedicated to NFTs


The differences between layer one Blockchain and layer two Blockchain include the following;

1) Layer 1 is the native Blockchain in which layer 2 is built on top

2) Layer 1 Blockchain has what we called Miners or Validators which act as security watchers of the Blockchain and those participating are rewarded with the native token why layer 2 has no such arrangements

3) Layer 2 are meant to solve specific problem of layer 1 eg scalability, gas fee security etc
