FPGA Cryptocurrency Mining Using FPGA
- 1. Prof. : Dr. Vahid Rashtchi Researcher: Mostafa Najmi Cryptocurrency mining using FPGA Winter 2018
- 2. Some kinds of cryptocurrencies • Bitcoin (BTC) • Ethereum (ETH) • Litecoin (LTC) • Ripple (XRP) • Bitcoin Cash • Ethereum Classic • etc...
- 3. Bitcoin What is Bitcoin(BTC)? • Best defined as a digital currency that only exists electronically • BTC is decentralized How does Bitcoin works? • Ruthless verification process which greatly minimizes the risk of fraud. What is mining? • Instead of single server >> Blocks verifies by users processing systems
- 4. Bitcoin Pros and Cons Pros: • It's decentralized and brings power back to the people • Freedom • Security • Low Transaction fees Cons: • Legal gray area • Liquidity • Volatility • Lack of adaption by business
- 5. BTCUSD daily chart and forcast
- 6. Kind of mining systems Most flexibility Least flexibility Least powerful Most powerful Can do almost any task Application specifics
- 7. Overview of mining systems CPU pros and cons Pros: • No specialized hardware required • A very good starting point to enter mining • Invaluable educational experience • It's fun to mine Cons: • Electricity cost • No Longer profitable • Constant wear and tear on your CPU
- 8. Mining speeds with different CPUs
- 9. Overview of mining systems GPU pros and cons Pros: • GPU is very good at complex computation • Easily sourced • Standard Hardware • High resale Value • Upgradable Cons: • High power draw • Not as powerful as ASICs • Requires large equipment • Less overall efficiency compared to ASICs
- 10. Overview of mining systems
- 11. Mining speeds with different GPUs
- 12. Overview of mining systems ASIC pros and cons Pros: • Low power use • A very high hash rate to specific coin • Physical size • High-profit margin Cons: • Cost can be very high • Low resale value • Short life span • Non-upgradable • Application-specific, for example, Litecoin ASIC can only mine litecoin

- 16. Mining speeds with different ASICs
- 17. FPGA miners Pros: • Flexibility • Tremendous power efficiency compared to GPUs • Can add to a GPU miner systems Cons: • Hard to setup • Are quite pricey compared to GPUs • FPGA have to be plugged into operational computers,just like GPUs
- 18. FPGA miners Why FPGA never been widely used in mining: 1-The first reason: • FPGA board are not easy to setup. • You have got to know how to program it for a certain algorithm especially you got to coding in verilog or VHDL- neither python nor c++ • Certain FPGA board perform 3x to 100 times better than a GPU 2-The second reason: • The creation of ASICs miners • Being ASICs as Plug and play hardware
- 19. FPGA miners Bitstream: The program written on a low-level programming language. Zetheron • No entry fees for owners-you pay only if the bitstream works • Plus,the access to the diversity of community-made bitstream will certainly grantee that we will be able to mine virtually any algo which we want • Table of all planned coins which Zetheron will release

- 23. Open source FPGA Bitcoin miner Performance: 109MHash/s on a Terasic DE2-115 Development board Both Xilinx and Altera are fully supported Required equipments • DE2-115 Development kit(based on cyclone IV EP4CE115 • USB Cable • Windows PC (Linux are also supported) • Altera's Quartus II (Installed on PC)
- 24. Open source FPGA Bitcoin miner Instructions: 1. Remove the clear acrylic cover on your board to prevent overheating 2. Navigate to 'scripts/mine' and follow the instructions in 'config.example.tcl' Do these each time you want to run the miner: 1. Connect the DE2-115 Development Kit to your PC through USB, connect its power, and turn it on. 2. Ensure that the DE2-115's drivers have been installed successfully on your PC. 3. Navigate to 'scripts/program' and run 'program-fpga-board.bat'. 4. Follow the instructions provided by the program-fpga-board script. Select the correct cable and programming file. Once programming has succeeded, the DE2-115 is now ready to mine!
- 25. Open source FPGA Bitcoin miner 5. Run 'mine.bat' 6. If working correctly, 'mine.bat' will leave a console window open where reports hashing rate, estimated hashing rate and accepted/rejected share information. 7. Profit! NOTE: • You need to re-program the DE2-115 every time it is powered off and on again. • Your PC needs to stay on and connected to the internet. It is acting like a controller for the FPGA, feeding it data and getting back valid hashes.
- 26. Conclusion • FPGA might bring flexibility and the miners back to common folk. • Although the price of xilinx FPGA card is about $5000 USD but those board will let us mine virtually any algorithm at any time. • FPGA hopefully become the all-in-one universal mining solution.
