GO VDF

Running Verifiable Delay Function in GO Execution example using ChiaVDF.

Run using Docker

Raise the docker container using docker compose. It produces a one-shot execution.

docker compose up --build

Run Locally (Ubuntu)

1. Load ChiaVDF submodule bu running:

git submodule update --init

2. Install in your device the required compiling tools.

sudo apt-get install cmake libgmp-dev libboost-system-dev build-essential -y

3. Create directory chiavdf/build, and then move into it.

mkdir chiavdf/build && cd chiavdf/build

4. Run CMake to configure the project, establishing flags to compile chiavdfc and ommit python library. Pass as parameter the directory in which CMakeLists.txt is located.

cmake -DBUILD_CHIAVDFC=ON -DBUILD_PYTHON=OFF ../src

5. Build Chia VDF Library.

make

By following the previous commands, we obtain a shared library: libchiavdfc.so, located inside chiavdf/build/shared.

6. Go back to root project's folder.

cd ../..

7. Export path of C wrappers, ChiaVDF shared library and libgmp.

export CGO_CFLAGS="-I/path/to/chiavdf/src/c_bindings"
export CGO_LDFLAGS="-L/path/to/chiavdf/build/lib/shared -L/usr/lib/x86_64-linux-gnu -lgmp"
export LD_LIBRARY_PATH="/path/to/chiavdf/build/lib/shared"

8. Run main program:

go run main.go
