My name is Zhangjiong Xuan. I come from Hangzhou Qulian Technology Co., Ltd. We have a team to research Algorand and VRF Algorithm. Now we have implement the VRF Algorithm in the Golang. And we think there is a good scenario in the Hyperledger Fabric. So we want to ask the communitty if it’s a good Idea to use VRF Algorithm into Ordering Service, to do a feature in the Ordering Service. I hope TSC group can have a discussion whether will receive this proposal. If both of you think it's a good idea .Maybe we can have a try to do this job .And make a more detailed design in the google docs.
