Use Besu-extended privacy (Deprecated)

caution

Tessera-based privacy is deprecated in Besu version 24.12.0 and later. Please read this blog post for more context on the rationale behind this decision as well as alternative options.

Besu provides an extended implementation of privacy allowing you to create a privacy group for a set of participants. You must specify the privacy group ID when sending private transactions.

To enable the PRIV API methods, use the --rpc-http-api or --rpc-ws-api command line options.

To create the privacy group containing the recipients of a private transaction, use priv_createPrivacyGroup.

To create an EEA-compliant private transaction, specify privacyGroupId when creating the signed transaction passed as an input parameter to eea_sendRawTransaction.

Privacy group type​

Privacy groups created using priv_createPrivacyGroup have a BESU privacy group type when returned by priv_findPrivacyGroup.
