I have use the hyper-ledger raft network with 2 organisations and 4 peers with the chain code installed, everything is working well. Now i am creating the react mobile app for creating the wallet and generating the key-pair for user with certificate. Is there any way that, i can sign the transaction offline and broadcast to network using the react or any libraries built for it?
he fabric client which derived from any SDK comes with the ability to sign a transaction offline.
