Private Blockchain
Private blockchains are not open to the public and are only accessible to a select group of people. This means that only authorized users can read the data on the blockchain and only authorized users can verify the transactions. Private blockchains are often used by businesses and organizations that want to keep their data confidential.
Permissioned Blockchain
Permissioned blockchains are a hybrid of public and private blockchains. They are open to the public, but only authorized users can verify the transactions. This means that anyone can read the data on the blockchain, but only authorized users can add new blocks to the blockchain. Permissioned blockchains are often used by businesses and organizations that want to allow some level of public access to their data but still want to maintain control over the network.
Each type of blockchain has its own advantages and disadvantages. Public blockchains are the most secure and transparent, but they are also the slowest and most expensive to use. Private blockchains are faster and cheaper to use, but they are not as secure or transparent. Permissioned blockchains offer a balance between security, transparency, speed, and cost.
The type of blockchain that is best for a particular application depends on the specific needs of the application.
