<p>Not yet to my knowledgw but Jack Dorsey with Square seems to be working on it, I cant wait for his first results...</p><p><a href="https://www.theverge.com/2022/1/14/22883500/jack-dorsey-block-bitcoin-mining-system-open-source-mainstream" target="_blank">https://www.theverge.com/2022/1/14/22883500/jack-dorsey-block-bitcoin-mining-system-open-source-mainstream</a></p>

<p>I don't know any alternatives but the project you shared looks interesting!</p>

<p>I'm not aware of any sourcecode. But solving hashes should theoretaically be possible to all modern Altera/Xilinx boards. </p><p><br></p><p>I highly doubt its performance and cost of the board (and electricity) could compete with ASICs </p>

<p>Yes, there are more recent open source FPGA Bitcoin miners available. Here are a few examples:</p><p><br></p><p>1. Butterfly Labs EasyMiner: This is an open source FPGA Bitcoin miner that uses an FPGA board based on the Xilinx Spartan-6 FPGA. The source code is available on GitHub, and the miner is compatible with both the Bitcoin and Litecoin networks.</p><p><br></p><p>2. X6500 FPGA Miner: This is another open source FPGA Bitcoin miner that uses an FPGA board based on the Xilinx Spartan-6 FPGA. The source code is available on GitHub, and the miner is capable of mining both Bitcoin and Litecoin.</p><p><br></p><p>3. IceDrill FPGA Miner: This is a newer open source FPGA Bitcoin miner that uses an FPGA board based on the Xilinx Virtex-7 FPGA. The source code is available on GitHub, and the miner is capable of mining both Bitcoin and Litecoin.</p>
