Public and Private Blockchain Networks
Public blockchain networks are open and permissionless networks that anyone can access without approval. Permissionless blockchain networks have no central authority and provide full transparency of block transactions. Blockchain networks that are open to the public are known as permissionless blockchain networks. Users have the ability to read, write, or modify transactions based on their needs. This particular type of blockchain network is a self-organizing blockchain and allows users to employ security measures such as encryption, timestamps, anonymity, and hashes.
Private blockchains are permissioned and restricted networks where participation is strictly controlled. These private blockchain networks provide limited blockchain services to users and are often used by organizations to maintain information privacy. User access is only granted to validated and authenticated users. Permissioned blockchain network is another term for private blockchain network. Additionally, selected or authenticated users can only access the shared ledger.
