If the first and second levels are clear to many, then have you ever wondered what the zero and third levels are? In this post we will tell the difference between different levels and give clear examples with projects
▪️Layer0
This is the fundamental level on which many blockchains are built together, and they can all easily interact with each other.
👉 For example: Cosmos, Polkadot.
▪️Layer1
Layer 1 blockchains are self-contained blockchains that can conduct transactions without the participation of other networks.
👉 For example: Aptos, Sui, Bitcoin, Ethereum.
▪️Layer2
Second-level blockchains are created to increase the scalability of first-level blockchains. They process transactions instead of L1 blockchains faster and cheaper, and then return the results of data processing to L1 blockchains.
👉 For example: Arbitrum, Optimism, opBNB, Scroll, zkSync, Linea, Base, StarkNet.
▪️Layer3
Although there are many jokes about how many L2 blockchains need L3 blockchains, in reality the third layer is no longer a blockchain. This level includes decentralized applications that are built on the blockchain.
👉 For example: Uniswap, Aave, Curve, PancakeSwap, SyncSwap.
