Layer1 and Layer2 blockchains are different in terms of their functionality and design. Here are some key differences between them: Main Function : Layer1 Blockchains : These are standalone blockchains that operate independently. They have their own consensus mechanisms and handle their security and transaction validation on-chain. Layer2 Blockchains: These are built on top of existing Layer1 blockchains and are designed to enhance scalability, reduce costs, and increase transaction speeds by processing transactions off-chain or through sidechains. Security : Layer1 Blockchains : They have their security provided by their native consensus algorithms ( e.g., Proof of Work or Proof of Stake). Layer2 Blockchains: They rely on the security of the underlying Layer1 blockchain, which means their security is tied to the security of the base chain. Scalability : Layer1 Blockchains : Typically, Layer1 blockchains have limited scalability, which means they might have l...
