Understanding the layers of Blockchain: A Detailed Guide | CoinGabbar

Those who are familiar with the Blockchain’s Trilemma know that Blockchain is not only based on the one core concept of decentralization. The tech behind it also needs a sense of scalability and security to work efficiently. Blockchains must be highly secure and impenetrable due to the lack of a centralized authority. They must also be incredibly scalable in order to accommodate growing numbers of users, transactions, and other data.

A combination of various cutting-edge technologies—cryptography, game theory, mathematical computations, and so on—enables them to efficiently perform operations. Distributed ledger technology (DLT) maintains information verified by cryptography among a group of users who agree through a specified network protocol. This complex functioning is further divided into layered architectures and protocols. Let’s take a closer look at it.

Blockchain Architecture Layers

Blockchain layered architecture is a one-of-a-kind method of transaction validation. There are five layers involved, each with its own set of functions. Let's get right into it and learn about the architecture and what each layer does. 


Hardware Layer 

First layer of the blockchain. It consists of hardware such as network connections, computers in the network, and data servers. Data servers host the data held by a blockchain, and machines on the blockchain network can share this data with one another. This results in the formation of a Peer-to-Peer (P2P) network in which information is validated by nodes or miners (or computers) on the network.
