About the issue of DKG, if we have free time, @alanchchen will help you. However, he is sick now. We apologize for not providing a sample yet. Meanwhile, we should update the Readme!
In cggmp, before you run the sign protocol, you should perform the protocols of DKG and refresh. The DKG protocol generates all shares and the refresh protocol gives us the other necessary data.
Our implementation does not include "Pre-sign". If you perform the sign protocol, then you will get a signature directly. You can refer to the uni-test: https://github.com/getamis/alice/blob/f4081e0922387b5a60ab709e5df9f680704d860f/crypto/tss/ecdsa/cggmp/sign/sign_test.go#L70
This uni-test can tell us how to use the sign protocol. If you have other problems, please let me know. Thanks a lot!

Hi all!
I'm trying hard to make a complete result of ECDSA-CGGMP, but I can't :(
About DKG -> I already posted an issue couple of days ago, please check it Sign -> This issue!
I was unable to make input configurations of a signing and found that the DKGresult and input of sign are very different. I thought probably that's because some important parts are missing: Auxiliary Information phase and Presigning phase in the paper. (some of them or all of them)
Are they implemented ? If yes, then please let me know what packages or functions to use to control the input configs. No! Then, can you give me any information to make it work? Or Do you have any plan to implement them/it?
This might be a silly question ... but anyway, thank you in advance!
