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_fpga_top

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

Architecture document is here

It optionally contains the following top-level engines (you can optionally include in a build via parameters):

• Equihash verification engine
• EC secp256k1 signature verification engine
• EC bls12-381 co-processor

ip_cores

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

• blake2b - A simple implementation of blake2b and a pipline-unrolled version for high performance.
• common - Packages and interfaces that are shared.
• fifo - Fifo implementations
• parsing - Blocks for parsing/processing streams, as well as testbench files.
• Karabutsa multiplier
• Barret reduction
• Resource arbitrators
