Different types of blockchain networks

Public	Private	Permissioned	Consortium
A Public blockchain, like Bitcoin, allows anyone to join and participate. The disadvantages may include the requirement for a significant amount of computational power, little or no transaction privacy, and weak security. These are important factors to consider for enterprise blockchain use cases.	A private blockchain network, like a public blockchain network, is a decentralized peer-to-peer network. However, the network is governed by a single organization, which decides who is allowed to participate, implements a consensus protocol, and maintains the shared ledger. This can significantly boost participant trust and confidence, depending on the use case. A private blockchain can be run behind a corporate firewall and even hosted locally.	Private blockchain networks are typically created by businesses. It is worth noting that public blockchain networks can be permissioned as well. This restricts who and what transactions can take place on the network. To attend, participants must first obtain an invitation or permission.	Multiple organizations can manage a blockchain. Who can submit transactions and access the data is determined by these pre-selected organizations. When all participants must be authorized and share responsibility for the blockchain, a consortium blockchain is ideal.
