Layering Architecture of Blockchain

Hello friends,

In our last series of blockchain articles, we have discussed what is web 3.0 and how web 3.0 is the foundation for blockchain.?

To continue our blockchain knowledge series, let's know about layering architecture of Blockchain in this article.

Blockchain technology:

A unique fusion of various technologies, including cryptography, game theory, etc., is blockchain technology.

Blockchain technology improves productivity, lowers operating costs, and does away with middlemen to provide advantages like transparency and impenetrable security.

You may have heard individuals discuss the many layers of blockchain when discussing Web 3.0, Decentralized Ledger Technology (DLT), and particularly blockchain. But what are they specifically, and why are they so important?

In this essay, we'll examine the importance of layers in IT ecosystems and how the Blockchain setup functions in accordance with each layer.

The Architecture of Layers

Blockchains do not have a central authority, so all transactions must be secure and data must be kept on a distributed ledger securely. The distributed ledger technology (DLT) operates according to a predefined protocol, with the network's many computers (or nodes) reaching a "consensus" to validate transactional data. Each node adds, checks, and modifies new entries as they come in. Blockchains have a layered design that enables this particular type of transaction authentication.

Some blockchain experts claim that blockchain technology consists of five layers:

• Infrastructure or hardware layer
• Data layer
• Network layer
• Consensus layer
• Application and presentation layers

Blockchain technology layers, however, can also be grouped into:

• Layer 0
• Layer 1
• Layer 2
• Layer 3

Hardware or infrastructure layer

The blockchain data is safely backed up on a data server. Peer-to-peer networks, or P2P, are the foundation of blockchain platforms. Through these networks, one node can easily and quickly connect with other nodes to share data. This data interchange is made possible by the client-server architecture.

Data Layer

A chain of hashed blocks containing transactional records is known as a blockchain. The Genesis block is the very first block in the blockchain. Following then, an iterative mechanism is used to link each new block that is added to the blockchain to the Genesis block. And in doing so, the blockchain continues to grow.

Using the sender's wallet private key, each transaction is "digitally signed." The data cannot be accessed or altered by anybody else because this key is only visible to the sender. The digital signature, which is encrypted to ensure the highest level of security, further protects the owner's identity. This concept is known as "finality" in the context of blockchain technology.

It is inaccessible due to data encryption. Tampering with data access is practically impossible.

Network Layer

To determine whether a transaction is legitimate, the P2P infrastructure enables many nodes to exchange transaction data. This indicates that in order to communicate fast, every node on the network must be able to find other nodes. The network layer enables this "inter-node communication." Due to its control over block creation, block insertion, and node identification, this layer is often referred to as the "Propagation Layer."

The Consensus Layer

This layer, which is one of the most crucial for blockchain functionality, is in charge of transaction authentication. Without this layer, the system won't function properly because the validation of transactions won't happen. This layer carries out the protocol, which necessitates a certain quantity of nodes in order to validate a single transaction.

Because the role is distributed and no node has sole control over any transactional data. It preserves the decentralized nature of the blockchain and is also known as a consensus mechanism.

Layers for applications and presentations

The applications that end users employ to create blockchain network connection make up the application layer. The application layer is made up of scripts, frameworks, UIs (user interfaces), APIs (application programming interfaces), chaincode, smart contracts, and Dapps (decentralised applications).

Blockchain technology layers, however, can also be classified as Let's take a look at those layers, such as layer 0, layer 1, and so on.

Layer-0

Layer-0 serves as the network architecture for the blockchain and is made up of the hardware, protocols, connections, and other elements that make up a blockchain ecosystem. You could think of this layer as a "network of blockchains."

Layer-1

The majority of duties that maintain a blockchain network's core functions, including as dispute resolution, consensus, programming languages, protocols, and limitations, are carried out by Layer- 1. The first layer represents the blockchain itself.

Layer-2

Layer-1 is updated by a second network, Layer 2, which also controls all transactional validations. Layer-2 sits on top of Layer-1 in the blockchain ecosystem and regularly exchanges information with it. On the other hand, Layer-1 is simply in charge of overseeing the creation and adding of new blocks to the blockchain.

Take the Lightning Network as an illustration of a layer 2 blockchain that has been implemented on the Bitcoin blockchain.

Layer-3

the last and most apparent layer of the blockchain ecosystem. Participants will eventually communicate with the user interfaces at Layer-3 (UI). This layer seeks to provide simplicity and convenience of use while interacting with L1 and L2.

Wrap Up:

Building a scalable system is the only way to solve the scalability trilemma because each level of the blockchain has its own set of limitations.
