This is a proof-of-concept implementation of Efficient Asymmetric Threshold ECDSA for MPC-based Cold Storage.
The code is only for demonstration and benchmarking purposes, do not use in production!
The code does not implement any communication between the parties, everything runs in a single process on the same machine and memory is shared between all parties.
Build:
make
To generate 1000 persignatures, and sign 50 of them, between 5 parties (1 offline and 4 online):
./benchmark -pre 1000 -sign 50 -parties 5
To hide debug info add: -no-print.
To hide timing and communication measurements info add: -no-measure.
To save execution time it is possible to mock execution of some of the protocol phases, add:
-mock-keyto mock key generation phase.-mock-preto mock presigning phase.-mock-cmpto mock CMP part of signing phase.
