Use EEA-compliant privacy


Orion features have been merged into Tessera! Read our Orion to Tessera migration guide and about all the new Tessera features.

When using Hyperledger Besu EEA-compliant privacy, the group of nodes specified by privateFrom and privateFor form a privacy group, to which Tessera assigns a unique privacy group ID.

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

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

Privacy group type

Privacy groups created when specifying privateFrom and privateFor have a LEGACY privacy group type when returned by priv_findPrivacyGroup.
