Privacy Manager

A Privacy Manager is required to use private transactions in Quorum.

The Privacy Manager is a separate component that is concerned with the storing and distribution of encrypted private transaction data between recipients of a private transaction.

To enable private transactions, use the PRIVATE_CONFIG environment variable when starting a Quorum node to provide the node with the path to the Privacy Manager’s .ipc socket, e.g.:

export PRIVATE_CONFIG=path/to/tm.ipc

The Privacy Manager has two components:

• Transaction Manager: See the Homepage and Tessera’s Transaction Manager page for more details on the responsibilities of the Transaction Manager
• Enclave: See Homepage and Tessera’s Enclave page for more details on the responsibilities of the Enclave

Implementations

• Tessera is a production-ready implementation of Quorum’s privacy manager. It is undergoing active development with new features being added regularly.

• Constellation is the reference implementation of Quorum’s privacy manager. It is still supported but no longer undergoing active development of new features.
