# zcash-fpga

Repo for Zcash FPGA projects code and documents.

## Overview

These have been designed targetted for Xilinx boards (US+) and therefore contain Xilinx-specific IP.

## zcash_verif

This is the top level for the Zcash verification FPGA board. It targets both Xilinx Virtex UltraScale+ FPGA VCU118 Evaluation Kit, and Amazon EC2 F1 Instances.

Architecture document is [here]()

## ip_cores

These contain custom IP cores used in the projects in this repo.
