4. Let node 1, 2, 3, 4, 5 accept the request for a co-management public key

  • key is the unique ID of this request command and is obtained in step 3.

5. Obtain the public key according to the key of the Request of generating public key

curl -X POST -H "Content-Type":application/json --data '{"jsonrpc":"2.0","method":"smpc_getReqAddrStatus","params":["0x99eb5c871ce7dc1a2dfd22339c9266894b3fb7aebe2e7a97a6db16b7f2b0e095"],"id":67}' http://127.0.0.1:5871

6. Delete data from one of the nodes

Let's say node 5 is deleted.（Suppose enodeId of node 5 is XXX, then find the dcrmdbXXX and skXXX folders in ~/.Anyswap-MPCNode/dcrmdata/ or the path specified by datadir parameter when gsmpc startup and delete them）

7. Set new groups

Now node 5 is to be replaced with node 6, and suppose node 1, 2, 3 (the threshold is 3/5) is involved to perform the reshare procedure.

  • get group id of node 1,2,3,4,6 and get subgroup id of node 1,2,3.At the end of this step, it returns the group id of 1, 2, 3, 4, 6 and subgroup id of 1,2,3.
  • the second parameter is an array of 1,2,3,4,6 node enodes.
  • the 1,2,3 nodes participating in the reshare are the first three of the array in turn,... and so on.

  • sig: parameter must be added with the signature enode of 1, 2, 3, 4, 6
  • mode: must be specified. Must be consistent with step 3.
  • gid: the group id of 1, 2, 3, 4, 6
  • tsgid: the subgroup id of 1, 2, 3
  • pubkey: the public key to be reshared,obtained in step 5.
