Layer of blockchain

While it may initially appear unnecessary to grasp the various layers of blockchain technology, users don't necessarily require an intricate understanding of this concept. However, having a fundamental grasp of these layers can aid users in comprehending the rationale behind the creation of diverse blockchains and currencies, as well as discerning their distinctions.

If certain aspects of this topic seem perplexing, there's no cause for concern, as users can gradually delve deeper into these subjects over time. Essentially, blockchain layers serve as a conceptual framework for categorizing the diverse elements within a blockchain network. This model aids in enhancing comprehension of how a blockchain network operates and the interplay among its various components.

Typically, blockchains are segmented into 4 layers :

This layer includes the hardware and software needed to run the blockchain network. For example, this layer includes the network nodes, the communication network between the nodes, and the software required to implement the blockchain protocols.

Data layer: This level encompasses the information stored within the blockchain network, comprising financial transactions, smart contracts, or other relevant data.

Network layer: This layer is responsible for the communication between the nodes of the blockchain network. This layer provides protocols for sending and receiving data between nodes.

Consensus Layer: This layer holds the responsibility of authenticating transactions and appending them to the ledger. It employs consensus algorithms for transaction validation.

If you're not fully grasping all the material, don't fret. With time, you'll grow more accustomed to these ideas. At this point, you don't require further insight into this topic. Now, considering how blockchains operate across various layers, they can be categorized into four tiers, ranging from 0 to 3. Prominent blockchains like Ton, Bitcoin, Ethereum, etc., belong to layer 1.
