What kinds of blockchain exist?


What has been described above is the purest form of blockchain, commonly referred to as a public, permissionless blockchain. This means that anyone can access that network and read its transactions.


owever, other blockchain types also exist and are more suited to other kinds of use. For example, some networks should not be accessed by everyone or information should only be shared with some participants depending on the content. Such a blockchain is commonly referred to as a “permissioned” blockchain, where either access to the network, or the information stored in it, is restricted in some way. How organizations interact (e.g., across supply chains), is often suited to such permissioned access. However, by introducing permissioned access, the quality of trust and immutability is reduced as there are typically less participants in the chain enabling consensus, particularly compared to the largest public blockchains mentioned above. l
