zk-benchmark

Benchmark of multiple zk implementations.

The benchmark results can be found in this blog.

SHA256 benchmark

Define a single circuit that compute sha256 for N bytes data

• one private input: x, len(x) = N = 2^k
• one public input: h = sha256(x)

func benchmark(x, h):
    assert(sha256(x) == h)
