BTC Miner - An Open Source Bitcoin Miner

BTCMiner is a Bitcoin Miner software which allows you to make money with your ZTEX USB-FPGA Module. Since these FPGA Boards contain an USB interface no additional hardware (like JTAG programmer) is required and low cost FPGA-clusters can be build using standard USB hubs.

Features

• Supported FPGA Boards:
  • Spartan 6 USB-FPGA Module 1.15b with XC6SLX75: 90 MH/s (typical)
  • Spartan 6 USB-FPGA Module 1.15d with XC6SLX150: 215 MH/s (typical)
  • Spartan 6 USB-FPGA Module 1.15x with XC6SLX150: 215 MH/s (typical)
  • Spartan 6 USB-FPGA Module 1.15y with four XC6SLX150: 860 MH/s (typical)
• Dynamic frequency scaling / overclocking based on error measurement, i.e. BTCMiner automatically chooses the frequency with the highest rate of valid hashes.
• Cluster mode: one software instance can control many FPGA Boards (up to several hundreds, limited by the number of USB host controllers)
• Hot-plugging: new FPGA Boards can be added / removed during runtime
• Stale reduction by Long Polling and block monitoring
• Backup server / pools
• Possibility of enumeration of FPGA Boards and cluster partitioning using that numbers
• Power save mode after 5min inactivity of per command
• Temperature monitoring and overheat shutdown (USB-FPGA Module 1.15y rev. 2)
• Overheat protection by shutdown if error rate increase to much
• Logging
• Package is Open Source
• Ready-to-use Bitstream, i.e. no Xilinx Software or Licence required
