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. Read the contest intro to participate in the Proof of Space Contest.

./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>There is an experimental implementation which implements some of the Hellman Attacks that can provide significant space savings for the final file.
make hellman
./HellmanAttacks -k 18 -f "plot.dat" -m "0x1234" generate
./HellmanAttacks -f "plot.dat" check <iterations>Finally, a python implementation is also provided for the verification algorithm.
