We use Bridge Protocol sir. The Bridge Protocol ensures privacy preservation by linking PrivateChains to MainChain. The innovation here is that the Bridge Protocol while private transactions details are distributed securely over the PrivateChain, the protocol provides a secure communication between both private and main chain by abstracting details and creating cryptographically verifiable proofs on both chains to ensure system transparency and security. The Bridge Protocol help private chains submit their data to the Mainchain for validation and each private chain need to pay fee using the HETACOIN.
