Chia’s Proof of Space is a fascinating technology designed for cryptographic proof mechanisms, primarily using C++. This article aims to guide you through the steps needed to compile, test, and run the Proof of Space functionalities. Whether you’re a beginner or a seasoned developer, you’ll find this guide user-friendly and straightforward.

Understanding the Basics

Before diving into the technicalities, let’s use an analogy. Imagine a library where books are stored in such a way that you can prove you have access to a particular book without actually having to show it. The more books you have, the more you can prove your claim. Similarly, Chia’s Proof of Space allows users to demonstrate that they have allocated storage space without exposing the data itself. This is achieved through various tools involved in the code such as a plotter, prover, and verifier.

Getting Started with C++ Usage

To start using the Chia Proof of Space, you need to compile the code. Here are the detailed instructions:

Compile the Code

• Ensure you have CMake version 3.14 or higher installed.
• Open your terminal and execute the following commands:

bash
# Requires cmake 3.14+
mkdir -p build
cd build
cmake ..
cmake --build . -- -j 6

Static Compilation with glibc

If you wish to statically compile Proof of Space, follow these steps:

bash
mkdir -p build
cd build
cmake -DBUILD_PROOF_OF_SPACE_STATICALLY=ON ..
cmake --build . -- -j 6

Running Tests

• To run the tests, simply execute:

bash
./RunTests

Using the Command-Line Interface (CLI)

Chia’s Proof of Space supports several CLI commands that allow you to create, prove, and verify proofs. Here are some example commands:

bash
./ProofOfSpace -k 25 -f plot.dat -m 0x1234 create
./ProofOfSpace -k 25 -f final-plot.dat -m 0x4567 -t TMPDIR -2 SECOND_TMPDIR create
./ProofOfSpace -f plot.dat prove <32 byte hex challenge>
./ProofOfSpace -k 25 verify  <32 byte hex challenge>
./ProofOfSpace -f plot.dat check iterations

Benchmarking

To benchmark the performance of the Proof of Space, you can run the following command:

bash
time ./ProofOfSpace -k 25 create

Handling Hellman Attacks

For those interested, there’s an experimental feature for implementing Hellman Attacks:

bash
./HellmanAttacks -k 18 -f plot.dat -m 0x1234 create
./HellmanAttacks -f plot.dat check iterations

Python Bindings

If you prefer working in Python, you can install the bindings. Here’s how to do it:

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

Running Python Tests

Testing in Python utilizes `pytest`:

bash
pytest .tests -s -v

Troubleshooting

Here are some common troubleshooting tips if you encounter issues during installation or execution:

• Ensure that you have the correct version of CMake installed.
• Check that your system architecture is 64-bit, as the software exclusively runs on this platform.
• If you face issues with commands not being recognized, ensure you are in the correct directory where the binaries are compiled.
• For any dependency errors, verify that you have all required libraries installed.
