Permissioned Blockchain Definition - Glossary

Permissioned Blockchain is a blockchain with restricted access, allowing only authorized participants to validate and manage transactions.

Permissioned Blockchain is a type of blockchain where access is restricted to specific participants. Unlike public blockchains, which allow anyone to join and validate transactions, permissioned blockchains require authorization to participate. This control ensures higher security, privacy, and efficiency, as the nodes are vetted and known to the network. Typically used in enterprise settings, they enable organizations to maintain control over who can view and alter the data. Permissioned blockchains are ideal for industries requiring compliance and confidentiality, such as finance and healthcare.
