Blockchain technology has been growing in popularity recently, sparking interest in businesses and organizations across multiple industries.
One of the reasons for its popularity is its versatility, and there are several types of blockchain available. In this article, we will explore the different types of blockchain, including public, private, hybrid, and more.
Public Blockchain
Public blockchain is the most well-known type of blockchain. Bitcoin is one of the most famous examples of public blockchain. It is an open-source blockchain where transactions are transparent and fully accessible to the public. Anyone can check the transactions or add new transactions on the network. Bitcoin miners validate the transactions and create new blocks to the blockchain.
The security of public blockchain is ensured by the decentralized nature of the network. Since there is no central authority, fraud is harder to commit, making it an ideal option for financial transactions.
Private Blockchain
Private blockchain, as the name suggests, is a blockchain intended for private use. Unlike public blockchain, only authorized users can access and propose transactions on the network.
Private blockchain is more centralized than public blockchain, and the network is maintained by a group of people or an institution. It can also be used to secure transactions between business partners.
This type of blockchain is favored by companies with strict privacy requirements, such as healthcare, banking, or legal services.
Hybrid Blockchain
Hybrid blockchain combines the best aspects of both public and private blockchains. Specific parts of transactions can be kept private while other parts of the same transaction can be made public. For instance, a hybrid blockchain can be used to keep sensitive information private while still providing transparency to the transaction’s less sensitive parts.
Hybrid blockchain is perfect for supply chain management, where transparency is required for some parts but not for everything.
Consortium Blockchain
Consortium blockchain is a more centralized version of hybrid blockchain, where the network is established by members of a consortium.
Consensus among members of the consortium is required before any transaction is validated. It is also possible to restrict access to the consortium’s transaction records to the members alone, making it ideal for consortium members who need to manage a shared asset or system.
Conclusion
There are several types of blockchain available, each suited to different needs. Public blockchain offers transparency and decentralized control, making it an ideal option for public financial transactions. Private blockchain is for private transactions where confidentiality and privacy are essential. Meanwhile, hybrid blockchain combines the best aspects of public and private blockchain, making it perfect for supply chain management. Finally, consortium blockchain is ideal for consortium members who need to manage a shared asset or system.
