What Are the Technical Standards of Blockchain: A Comprehensive Analysis of the Underlying Specifications of Blockchain

Blockchain technology has become a hot topic in today's technology industry. With the rise of virtual currencies such as Bitcoin, blockchain is not only an innovative payment method but also an important driving force for transformation across various industries. To ensure its sustainable development, it is particularly important to establish corresponding technical standards. This article will explore in detail the technical standards of blockchain, including its basic concepts, technical architecture, key features, and standardization requirements in different scenarios.

The basic concept of blockchain

Blockchain is a type of distributed ledger technology whose core idea is to store data across multiple nodes. Unlike traditional centralized databases, the data structure of blockchain is organized in "blocks" that are sequentially connected, forming a chain-like structure. Each block contains a portion of data and the hash value of the previous block, ensuring data integrity and security through cryptographic methods.

1.1 Core Features of Blockchain

DecentralizationBlockchain maintains the validity of the network through the collaboration of various nodes, without the need for a central authority.

ImmutabilityOnce data is written to the blockchain, it cannot be modified, ensuring the authenticity of the information.

TransparencyAll participants can access and verify the data simultaneously, greatly enhancing trust.

Smart contractContracts that are automatically executed through programming improve the efficiency of business processes.

2. Technical Architecture of Blockchain

The technical architecture of blockchain can be simply divided into three layers: the infrastructure layer, the network layer, and the application layer.

2.1 Infrastructure Layer

The infrastructure layer mainly includes the basic components of blockchain, such as nodes, consensus mechanisms, data structures, etc. This layer is the foundation of blockchain technology.

Full node: Computers participating in the blockchain network, with each node having an identical copy of the data.

Consensus mechanismTo solve the problem of reaching consensus in a decentralized network, blockchain uses mechanisms such as Proof of Work (PoW) and Proof of Stake (PoS).

Data structuringData structures such as Merkle trees improve data processing efficiency while ensuring data security.

2.2 Network Layer

The network layer is responsible for communication between nodes. It is a crucial part of blockchain technology, ensuring that data is transmitted securely and quickly between nodes.

P2P networkThrough a peer-to-peer network, nodes are directly connected to each other, resulting in high data transmission efficiency.

Protocol and Design of the ChainStandardize the communication protocol between nodes to ensure stable and effective information transmission.

2.3 Application Layer

The application layer serves as the interface for users to interact with the blockchain, such as wallets, exchanges, decentralized applications (dApps), and so on.

User InterfaceA user-friendly interface can enhance the user experience, making it easy and efficient for users to operate.

Smart contractA contract that is automatically executed under specific conditions, widely used in fields such as finance and law.
