With tongue firmly in cheek, I wonder how long before it becomes cost effective to mine Bitcoin with raw 74xx logic?

- nickpsecurity 9y agoBitcoin miners are already using custom ASIC's on expensive, process nodes. Anyone using discrete logic would be running at a snail's pace compared to them.
- tudorconstantin 9y agoWhat about mining ethereum on FPGA, would it be suited?
- nickpsecurity 9y agoI don't know specifics on Ethereum. Basically, it has to be within the hardware constraints of FPGA's where CPU's, GPU's, and ASIC's don't convey an advantage.
- hrac 9y agoDo you know how bitcoin miners use FPGAs? They're used for communication somehow. The Antminer S7 uses an SoC FPGA which allegedly was being used with ASICBoost.
- nickpsecurity 9y agoYou can implement many forms of I/O on FPGA's that let you bridge things that otherwise can't communicate for whatever reason. The FPGA can also be used to accelerate I/O vs a software implementation. For example, many network devices offload TCP/IP from the host. Finally, the connecting systems might have the necessary I/O built-in but FPGA accelerates some computational part of it. You see that in compression, TLS or IPsec engines. I don't know what Bitcoin people are doing. The above are common use cases, though.

- tyingq 9y agoThat's (sort of) asked and answered in the comments :) "it would be theoretically possible. But if you calculate that... it isn't. For example: a DE0-Nano board ($79) mines at 12 MH/s. It has 22320 logic elements. Assuming the slices are equivalent, you would have to have 22320 of these boards. Each containing 12 7400 chips."
