What Is a Permissioned Ledger?
A permissioned ledger is a type of distributed ledger technology (DLT) that allows only certain users to access and modify the data stored on it. It is different from public blockchains, which are open for anyone to view or edit. Permissioned ledgers provide more control over who can access and make changes to the data, making them ideal for businesses looking for greater security and privacy when managing their digital assets.
Permissioned ledgers use cryptography-based authentication methods such as digital signatures or private keys to ensure that only authorized users have access to the network. They also employ consensus algorithms like proof-of-stake or Byzantine Fault Tolerance (BFT) in order to validate transactions without relying on miners like with public blockchains. This makes permissioned ledgers faster than traditional databases while still providing high levels of security and trustworthiness among participants in the network.
