rosen tss project

This project is used for keygen, sign and regroup operations on eddsa and ecdsa protocols in threshold signature. It is based on Binance's TSS-lib. For massage passing you should run ts-guard project and set it's port as p2pPort argument.

build command

make build

config

set peer home address, log configs and operation timeout in second.

run command

./roesnTss [options]
  -configFile string
        config file (default "./conf/conf.env")
  -p2pPort string
        p2p port (e.g. 8080) (default "8080")
  -port string
        project port (e.g. 4000) (default "4000")
  -publishPath string
        publish path of p2p (e.g. /p2p/send) (default "/p2p/send")
  -subscriptionPath string
        subscriptionPath for p2p (e.g. /p2p/channel/subscribe) (default "/p2p/channel/subscribe")

There are 6 endpoint.

1. keygen
   • used to generate key between peers

     curl --location --request POST 'localhost:4000/keygen' \
     --header 'Content-Type: application/json' \
     --data-raw '{
     "peersCount" : 3,
     "threshold" : 2,
     "crypto": "eddsa",
     "callBackUrl": "http://localhost:5051"
     }'

2. sign
   • used to sign a message between peers
   • note: At least threshold+1 parties can recover the private key

     curl --location --request POST 'localhost:4001/sign' \
     --header 'Content-Type: application/json' \
     --data-raw '{
     "crypto" :"eddsa",
     "message" : "951103106cb7dce7eb3bb26c99939a8ab6311c171895c09f3a4691d36bfb0a70",
     "callBackUrl": "http://localhost:5051"
     }'

3. regroup
   • used to regroup and recreate and re-sharing key between new peers

     curl --location --request POST 'localhost:4000/regroup' \
     --header 'Content-Type: application/json' \
     --data-raw '{
     "peersCount" : 6,
     "newThreshold" : 2,
     "oldThreshold": 2,
     "crypto": "eddsa",
     "peerState": 0,
     "callBackUrl": "http://localhost:5051"
     }'

4. message
   • used as an entry to get messages from ts-guard.

   {
     "message": "message",
     "channel": "channel",
     "sender": "sender"
   }

5. import
   • used to import private key of peer

   curl --location --request POST 'localhost:4000/import' \
    --header 'Content-Type: application/json' \
