Privacy is the ability to keep transactions private between a set of participants. For those applications that require the exchange of sensitive information between parties, it can be convenient to enable a private side-channel. In these side-channels, the information is shared encrypted only between authorized participants and a timestamp is recorded in the public LACChain network. There is a private transaction manager particularly suitable for Hyperledger Besu Networks developed by Consensys, named Tessera (https://docs.tessera.consensys.net/en/stable/). We have enable quick development guides of Tessera nodes integrated with LACChain writer nodes, for those entities interested in setting up private channels. Go to section [Develop -Private Channels].
