1  Alternate cryptocurrencies / Mining (Altcoins) / Re: DIY FPGA Mining rig for any algorithm with fast ROI on: June 28, 2018, 12:23:37 AM
>Next up on my implementation list is SHA-224 and Neoscrypt.

Hi, I'm Dan, an engineer at StarDot Technologies. I wrote a 100% parallel H.264, jpeg, and color processing for our cameras.  

Our boss has become interested in digital coins.  He's even got mining farms!  

He wanted to know if we could productize digital coin mining into the "internet of things".  He's hoping to add transactions to the block chain, so his mining farms earn more money for more years.  

It's pretty easy to make a $50 ethereum mining card (cost) using one fpga (we get excellent prices on Xilinx), a raspberry pi style linux, and 4 out of date (cheaper) memory cards.  It'd be as wide of memory as the 1070 cards but with 1/4th the memory speed.  

As an add-on to another device, it could be good.  Here's an example. Tokyo is covered in Pachinko machine businesses, which have  rooms filled with the machines, and men sitting there playing all day long for valuable prizes (which they sell out the back to circumvent gambling laws).

Why not add that low cost mining card to some of those, and let them earn money from whatever is the best coin to mine that day. Easy to make them change if they're hooked to the network and FPGA based.

When the machines in that business (all together) earn a full coin, they'd give it out in response to a certain level of play, lighting up and making all kinds of noises where the win takes place.  Owners would be motivated to buy more of that type of machine, so the fireworks payout would happen more often.   And, it would add more transactions to the block chain, which is good for all of us.

Many such other things are possible.  But the hardware needs to be open source, flexible, and a lot less expensive.

I'm designing such devices, but I've only looked at bitcoin and ethereum algorithms in detail.   Could you tell me, are any of the coin algorithms you're aware of,  bus transfer intensive?  Do I need a faster interface to get data into the FPGA during operation?  I don't with ethereum or bitcoin.

I'd hate to design it with a bottleneck which prevented mining some newer coins.
