Chia proof of space plotting, proving, and verifying (wraps C++)

Project description

# 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](https://www.chia.net/assets/proof_of_space.pdf) to learn about what proof of space is and how it works.

## C++ Usage Instructions

### Compile

`bash mkdir -p build && cd build cmake ../ cmake --build . -- -j 6 `

### Run tests

`bash ./RunTests `

### CLI usage

`bash ./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

`bash 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.

`bash ./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

`bash python3 -m venv .venv . .venv/bin/activate pip3 install . `

### Run python tests

Testings uses pytest. Type checking uses pyright, and linting uses flake8.

`bash py.test ./tests -s -v `
