Independent public chain development refers to the establishment of an independent public chain network beyond the existing blockchain network. Compared to developing on existing blockchain networks, the significance of independent public chain development is that it can more flexibly and autonomously control the development direction and functions of the public chain, while also better protecting the security and privacy of the public chain. Independent public chain development can not only meet the needs of different application scenarios, but also further promote the development and application of blockchain technology in the future.
Steps and precautions for chain development
Before conducting independent public chain development, it is necessary to have a deep understanding of the technical characteristics and development process of the public chain. Below is a brief introduction to the steps and precautions for public chain development.
- Determine the technical framework and mechanism of the public chain
The first step in public chain development is to determine the technical framework and mechanism of the public chain, including consensus mechanism, node election mechanism, encryption algorithm, storage method, etc. Different technical frameworks and mechanisms will have different impacts on the performance, security, and privacy of the public chain, requiring comprehensive consideration of various needs and trade-offs.
- Build and configure public chain nodes
The public chain node is a fundamental part of the public chain network, and building an independent public chain is a very important step in public chain development. Independent public chains refer to independent blockchain networks and ecosystems that do not rely on other public chains and can achieve their own currency issuance and smart contract functions. Building an independent public chain involves various aspects of blockchain underlying technology, such as consensus algorithms, blockchain storage, node management, etc. Therefore, rich technical accumulation and experience are required.
Before building an independent public chain, it is necessary to determine the application scenarios and technical architecture of the public chain. Firstly, it is necessary to clarify the positioning and application areas of the public chain, such as for digital currency payments, supply chain finance, social media, etc. Secondly, it is necessary to determine the technical architecture of the public chain, such as consensus algorithms, smart contracts, etc. Consensus algorithm is one of the core technologies of public chain, which can affect the security, efficiency, and degree of decentralization of public chain. Smart contracts can achieve functional expansion of public chains, such as digital asset issuance and decentralized applications.
