This repository implements a small demo use-case of BLS threshold signatures. We consider a scenario where a small company has perform payments to suplliers at the end of each month. The payments have to be approved by a subset of the board to be accepted.
In this repository we demonstrate an example on how to automate this process with threshold signatures.
Each member posses a BLS threshold signature private key, which can be used to sign payments with a BLS signature.
The payment will be accepted by the verifier if more than t members have signed the payment request.
The verifier should only accept the payment if the signature can be verified.
The code relies on the BLS threshold signature implementation from the libBLS library.
See libBLS for the basic requirements.
Example for Ubuntu
sudo apt-get update
sudo apt-get install -y automake cmake build-essential libprocps-dev libtool\
pkg-config yasm texinfo autoconf flex bison
To install and build the dependencies just run
bash ./setup.sh
After running installation script for the dependencies, the following command has to be executed to build the project.
cmake . && make
To start the non-interactive demo, run the bin/requested_demo executable.
The non-interactive demo consider 5 board members with a approval threshold of 3 and processes 50 payment requests.
To start the interactive console demo, run the bin/demo_app executable.
