This repository provides a Rust implementation of the Cryptobazaar auction protocol and includes the code for all of the validity proofs, the AV protocol, and the results vector computation.
To setup Rust, please follow the official installation instructions.
The minimum required Rust version is 1.80.1.
To run the Cryptobazaar tests, execute cargo test in the root folder.
To execute a sample Cryptobazaar auction, execute cargo run --example simple_e2e in the root folder. The corresponding code showing the protocol flow can be found in examples/simple_e2e.rs.
There are six different microbenchmarks in total, namely for the computation of the four validity proofs, the AV protocol, and the results vector.
To replicate the microbenchmarks provided in Table 1 of the paper, execute ./run-benchmarks.sh in the root folder.
Alternatively, you can run the benchmarks via Docker by executing docker build . in the root folder.
Note: Benchmark runtimes depend on your hardware and CPU architecture. For example, enabling the asm feature utilizes AVX instructions on Intel CPUs for faster performance. On Apple Silicon, AVX instructions are not available, so runtimes may differ. For example, on an Apple MacBook Pro M2 Max with 96 GB RAM, the benchmarks take about 1h to finish.
