Remove database access from blockchain, and handle headers instead of blocks Avoid processing blocks and unfinished blocks that we have already seen. Also adds test for load. Plotting improvements
Chia Proof of Space
A prototype of Chia's proof of space, written in C++. Includes a plotter, prover, and verifier. Only runs on 64 bit architectures with AES-NI support. Read the Proof of Space document to learn about what proof of space is and how it works.
C++ Usage Instructions
Compile
git submodule update --init --recursive
mkdir build && cd build
cmake ../
cmake --build . -- -j 6
Run tests
./RunTests
CLI usage
./ProofOfSpace -k 25 -f "plot.dat" -m "0x1234" generate
./ProofOfSpace -f "plot.dat" prove <32 byte hex challenge>
./ProofOfSpace -k 25 verify <hex proof> <32 byte hex challenge>
./ProofOfSpace -f "plot.dat" check <iterations>
Benchmark
time ./ProofOfSpace -k 25 generate
Hellman Attacks usage
There is an experimental implementation which implements some of the Hellman Attacks that can provide significant space savings for the final file.
./HellmanAttacks -k 18 -f "plot.dat" -m "0x1234" generate
./HellmanAttacks -f "plot.dat" check <iterations>
Python
Finally, python bindings are provided in the python-bindings directory.
Install
git submodule update --init --recursive
python3 -m venv .venv
. .venv/bin/activate
pip3 install .
Run python tests
Testings uses pytest. Type checking uses pyright, and linting uses flake8.
py.test ./tests -s -v
