Do the orderers see the transaction data in Hyperledger Fabric

Question

When a transaction is made in Hyperledger Fabric. It goes through the orderers for ordering. In this stage is the data visible to the orderers?

Answer 1

No, the orderers do not see the data of the transactions. If you do not want the data to go through the orderers at all, then you can use private data feature of Fabric. Or you can hash or encrypt the data in the client application before calling chaincode. If you encrypt the data, you will also have to create a decrypting mechanism after the data passes through the orderer.
