fpga_bitcoin_miner

Stratum Bitcoin mining client with support for CPU and FPGA mining. FPGA implementation of Sha256d for the Pynq-Z2 board. https://www.youtube.com/watch?v=M_AocgfvTIs

Requirements

Standard Python modules

Pynq-Z2 board - http://www.pynq.io/board.html

Tool versions

Xilinx Vivado 2019.1

Python 3.6.5

Instructions

Copy the overlays folder to the same directory as fpgaminer.py to match line 115 of fpgaminer.py

Copy the pynq module located in /usr/local/lib/python3.6/dist-packages/pynq to the same directory as fpgaminer.py

run python3 fpgaminer.py -h for command line arguments

To regenerate the Vivado project, open Vivado, cd to the FPGA directory, and run source sha256d.tcl in the TCL command prompt

Results

FPGA Sha256d: 40 Mhashes/sec

Hashlib Sha256d: 17 khashes/sec

Python Sha256d: 67 hashes/sec
