Which mode for Ethereum?

[while1]

@while1
no, you need the opposite, instead of scaling down, you need to scale up (or even better: first think A LOT about the feasibility and keyspace, number of password candidates, patterns etc etc etc). Instead of trying to use a Raspberry PI, that has (compared to a modern CPU or GPU rig, but we already stated here that for scrypt a CPU-rig might be better) almost no computing power, you need to scale up and use modern performant hardware that has a lot of computing power. hashcat doesn't support Raspberry PI for several obvious reasons (almost no computing power, no fan/cooling, not suitable for most of the advanced hard cracking jobs etc). In case of a scrypt-based algorithm you are better of with some modern Intel i9 processors or modern high-performant Intel Xeon processors (or similar). Good luck cracking.

Thanks, my total guesses are around ~400-500million. Unfortunately, Hashcat (for good reason) doesn't support Raspberry Pi. I benchmarked a Pyhton library making attempts on a Raspberry Pi B+ and am getting 2.11 attempts a second. I think I'm going to group a dozen together in a beowulf cluster and have them run along side my computer when that's available to work on it. Should take a few months

If I want to scale up where would I find a CPU-Rig or directions to build??
