Explain Blockchain Layers: L0, L1, L2, L3
In the bitcoin and blockchain sectors, the terms “layer one” and “layer two” protocols are sometimes used interchangeably. You may be interested in knowing more about the layers of bitcoin and must have thought about gaining blockchain education to understand the core infrastructure of the cryptocurrency. Many a time we come across questions like ‘how to become a blockchain engineer,’ or ‘how to specialize in blockchain infrastructure.’ We have tried to help you find answers to such questions by making you understand the basics of the layers involved in the Bitcoin ecosystem.
So, let’s examine the architecture in detail here, take a look:
- Layer 0
It is at layer zero that you will find the components that will aid you in making the blockchain a reality. The two top-tier cryptocurrencies, Bitcoin and Ethereum, are based on this infrastructure which makes them work smoothly. As the initial layer of all blockchain protocols, Layer 0 connects all other layers effortlessly to establish linked value chains, providing a more robust and developed alternative to smart contracts.
- Layer 1
The immutability feature of this layer serves as the basis of the unprecedented security offered by a typical blockchain ecosystem. When people refer to the protocol’s first layer as “Ethereum,” they are referring to Layer 1 of the protocol. This layer contains the rules and configurations that allow a blockchain network to function at its most fundamental level.
Every aspect of the system is under its control, from consensus methods and programming languages to block timing and dispute resolution mechanisms. This layer is also referred to as the implementation layer in certain circles. This notion is best shown by a layer one blockchain, such as Bitcoin.
- Layer 2
L2 solutions are the overlapping networks that are built on top of the base layer and provide additional functionality. Some base-layer exchanges are shifted to layer two as a technique of boosting scalability in the architecture of the protocols. It is a word used to describe solutions that allow an application to grow by processing transactions of the Ethereum Mainnet (layer 1) while yet retaining the same security features and decentralization as the mainnet. Transaction speeds are increased and gas costs are reduced through layer 2 solutions. The Lightning Network is a second-layer blockchain for the Bitcoin cryptocurrency.
- Layer 3
The application layer is often referred to as layer three, abbreviated as L3, in the context of networking. The technical specifics of the communication channel are hidden behind a user-friendly interface in the L3 applications. L3 apps are able to offer blockchains with their real-world applicability.
Layer three applications are required for the development of real-world blockchain applications. When compared to earlier layers, they will, however, be unable to capture nearly as much value as the blockchain that serves as the core of the network.
Scalability is one of the factors contributing to the lack of widespread acceptance of cryptocurrencies. A rise in the popularity of cryptocurrencies will put pressure on blockchain systems to grow. This problem of scalability will not be resolved until a new system is developed that can overcome all of the restrictions of both levels of the blockchain. The different layers of the blockchain ecosystem form the basic pillar for its working and operational capacities. The core inbuilt complexities of a blockchain help to make the system more efficient. Those willing to learn more about blockchain layers can enroll themselves in blockchain engineer certification courses available on multiple platforms. The process will help aspiring blockchain engineers to emerge as experts in the field.
