In a permissioned blockchain, only specific nodes can participate in the consensus mechanism, ensuring controlled participation.

In a permissionless blockchain, anyone can join the network and participate in the consensus process, promoting decentralization and openness.

Permissioned blockchains are typically used for public applications where transparency is critical.

Permissionless blockchains often have higher transaction speeds due to fewer participants.

Public blockchains allow anyone to read and write data, enhancing transparency but potentially exposing the network to more security risks.

Private blockchains restrict data access to specific members, enhancing transparency but potentially exposing the network to more security risks.

Public blockchains typically have centralized control over who can participate.

Both, public and private blockchains typically rely on a permissionless consensus mechanism to validate transactions.
