The Layered Structure of Blockchain and Architecture

The following six levels make up layers of blockchain architecture:

1. Hardware Infrastructure Layer

A blockchain data can be stored on individual nodes or even on a server at a data center. A client-server architecture is essentially the model used when users browse the web or use any apps to request content or data from application servers. But a blockchain is a peer-to-peer computer network that computes, verifies, and orderly records transactions in a shared ledger. Clients can communicate directly with one another and exchange data. A vast network of computers that share data is referred to as a peer-to-peer network. As a result, all data, transactions, and other relevant data are stored in a distributed database.

2. Data Layer

The data structure of a blockchain is described as an ordered linked list of blocks. Pointers and a linked list are the two main components of the blockchain’s data structure. Transactions are digitally signed to ensure the security and integrity of the data present in the layers of blockchain. Transactions are signed with a private key, and the signer can be verified by anybody who has a public key. The digital signature both checks for unity and identifies information modification. Since the data is encrypted with a specific, unique ‘hash’, it cannot be tampered with. The identity of the sender or owner is likewise shielded and not directly identifiable. A signature is therefore irrevocably connected to its owner and cannot be ignored.
