4.3 Duplex Transfer Channel

The second layer-2 design is duplex transfer channels between each MASP-client pair, with which we realize the atomic fee-ownership transfers. These channels are virtual 7 and instantiated by the specific smart contract. Within the channel, the participants can conduct multiple rounds of atomic transfers protected by the Hash Lock (HL) protocol. Only the channel initialization and closing need to be recorded on the anchor chain. Since the transfers happen inside channels, low latency can be guaranteed, and the workload of the anchor chain can also be alleviated. Next, we introduce the procedure of atomic fee-ownership transfer on the channel.
