Blockchain is a decentralized distributed database technology that has had a profound impact on all walks of life. Although blockchain has become increasingly popular over the past few years, it can be a little difficult for beginners to understand the concept of blockchain. This article will introduce the three basic types of blockchain: public chain, private chain and consortium chain to help you better understand this field.
Public chain
Public chains are also known as open blockchains. This type of blockchain is public and can be participated and accessed by anyone. On a public chain, anyone can create and publish blockchain applications without needing to obtain any special permissions or permissions. The biggest advantage of a public chain is its decentralized nature, which means there is no centralized authority or single entity controlling it. This makes public chains very secure, as an attacker would have to attack multiple nodes in the network simultaneously to compromise its integrity.
Every node on the public chain can verify the validity of transactions and blocks and add them to the blockchain. This process requires a high degree of computing power and resources, so the operation of public chains is more complex than other types of blockchains. The most famous example of a public chain is Bitcoin. Bitcoin is an open blockchain network that anyone can participate in. It is characterized by a high degree of decentralization and security.
private chain
Unlike a public chain, a private chain is a closed blockchain network that only authorized participants can access. This makes private blockchains more suitable for data management and exchange within organizations, such as within banks or companies. Private chains can improve efficiency by lowering access barriers and simplifying communication between nodes. Additionally, private chains can be customized and configured as needed, so they generally have greater flexibility and scalability.
The main advantage of private blockchains is controllability, since only authorized users can participate. This makes private chains more secure and reliable as it prevents data tampering by unauthorized persons. In addition, since private chains do not require computationally intensive mining work, their operations are also faster. Examples of private chains include Quorum, which is a private chain version of Ethereum developed by JPMorgan Chase and is mainly used for transaction processing between financial institutions.
Alliance chain
The consortium chain is a hybrid form between the public chain and the private chain. It is jointly controlled and managed by multiple organizations. Unlike private chains, consortium chains allow multiple organizations to share and collaborate on data and transactions, but these organizations must be authorized to join the network. The purpose of the consortium chain is to promote cooperation and interaction between organizations while maintaining data security and confidentiality.
The biggest advantage of the consortium chain is its scalability and efficiency. Because it only contains authorized organizations, the network can collaborate and coordinate more easily, increasing the speed and reliability of transactions. Alliance chains can also be used to manage supply chains to ensure data accuracy and traceability. An example of a consortium chain is R3 Corda, which is a consortium chain platform specifically used in the financial services industry.
Public chain
Public chains are also known as open blockchains. This type of blockchain is public and can be participated and accessed by anyone. On a public chain, anyone can create and publish blockchain applications without needing to obtain any special permissions or permissions.

Summarize
Blockchain technology is increasingly used in different fields. Public chain, private chain and alliance chain are the three basic types of blockchain technology. The public chain is completely decentralized and public, and is suitable for scenarios that require a high degree of security and anonymity. The private chain is closed and can only be accessed by authorized users. It is suitable for internal data management and exchange within the organization. The consortium chain is a hybrid form between the public chain and the private chain. It is jointly controlled and managed by multiple organizations and is suitable for cooperation and interaction between organizations.
Understanding these three types of blockchain can help you better understand the nature and application scenarios of blockchain technology. Whether it is a public chain, a private chain or a consortium chain, all have their own unique advantages and limitations. Therefore, when choosing to use blockchain technology, you need to make trade-offs and choices based on the actual situation.
