Some of you may remember me from my old account, Wolf0 (which I no longer have access to, as I got rid of the email I used long ago.) I'm still developing miners. Recently, I've been working on a miner for a coin called Ergo. Ergo uses a new proof of work known as Autolykos2 ( described here: https://docs.ergoplatform.com/ErgoPow.pdf ), which requires a large dataset in memory to mine. This dataset increases in size every 51,200 blocks, with a 2 minute block time. Currently mined with GPUs, and widely believed to be FPGA and ASIC resistant, this is the first FPGA miner (that I know of). While I have no clue what I'll be doing with it yet (releasing or otherwise), it performs slightly better than a 3070 per FPGA, at nearly half the wattage.

My miner is still in alpha stage - just a proof-of-concept, but I am currently mining it with a JC35 (Jungle Cat 35P) FPGA board which features two XCVU35P FPGAs, each with 8GB of HBM2 memory. Performance (currently, it will get better) is 178MH/s or so. Power is around 65W, at 0.75V core and 1.15V memory. Clocks are 415Mhz (core) and 1100Mhz (memory). These can go lower or higher to gain efficiency or hashrate.

As usual, I have a screenshot (and as usual, it is NSFW, so I did not inline the image): https://i.imgur.com/aIyhu2b.png
