Here are the four primary kinds of blockchains in the market:

– Public Blockchain: it’s a permissionless blockchain network allowing anybody to participate. It has zero restrictions and enables all parties to access a copy. Users can access all the records and do mining tasks.

– Private Blockchain: It runs in a private setting, like a controlled network. A private blockchain is regulated by a single company and is lesser than a public one. It’s also referred to as permissioned or business Blockchain.

– Consortium Blockchain: it’s a half-distributed form of Blockchain that different organizations manage. This means that various entities involved act as a node. Some institutions using consortium blockchains include banks and government agencies.

– Hybrid Blockchain: it’s a mixture of private and public Blockchains. This means that it uses both permissioned and permissionless qualities. The hybrid network allows users to regulate who accesses their data. A few records can be publicly available, while the others are confidential and accessible to chosen users.
