Layer 1 and Layer 2 tracks have thrived in recent years of blockchain development, and the Layer paradigm is still evolving. Last year, Ethereum scaling solution StarkWare revealed a number of Layer 3 concepts and ecosystems in the works, each dedicated to a specific use case. zkSync also announced in October that they are working on a layer 3 chain called "Opportunity," which aims to improve the scalability of the zkSync blockchain infrastructure.
What exactly is Layer 3 and what are its benefits? Before we get into Layer 3, let's go over Layers 1 and 2.
Layer 1 public chains, such as ETH, Solana, Avalanche, and others, do not need to be built on other chains and can operate completely independently. Consider Ethereum: it is now the platform with the most smart futures and DAPPs, as well as the public chain with the most locked-up encrypted assets and transaction volume. With the crypto market's recent explosive growth, the magnitude of activities such as on-chain transfers and future calls has also increased. Even when the market is not so good, users must deal with network congestion and high gas prices.As a result, how to solve Ethereum's expansion problem has always been one of the key issues in the encryption community, which is why Layer 2 was created.
Layer 2 is a self-contained ecosystem built on Ethereum that relies on Ethereum for security. In essence, Layer 2 is responsible for stripping and layering the functions of the public chain, leaving the consensus mechanism that provides security in Layer 1 and delegating calculation and execution to Layer 2. It allows the public chain to become the Layer 2 settlement layer, allowing it to complete a large number of transactions quickly and cheaply.
If Layer 1 is compared to a road, as its ecology becomes more abundant, more vehicles will drive on the road, causing congestion to worsen. Layer 2 serves as a diversion, similar to the viaduct built on this highway.
So, what exactly is Layer 3? Let's look at Vitalik, the founder of Ethereumsummary ,'s of Layer 3: "Layer 2 is for expansion, while Layer 3 is for customizable expansion." This customization precisely corresponds to the special scenarios employed by users and the application direction preferred by developers. Layer 3 also has the feature of weak trust extension, which limits data availability to trusted third parties or committees, further protecting user privacy and security."
In short, Layer 3 is built on the foundation of Layer 1 and multiple Layer 2. It addresses C-level users directly and can provide higher-level expansion solutions. Layer 2 can maximize operational efficiency, but it can't handle highly customized application scenarios. However, as an independent layer, Layer 3 provides personalized services, which can provide users with a better trading experience.
