Might I suggest that the min-spec, if developed, target the RISC-V Rocket architecture (running on FPGA, I suppose) as a reference point for performance? This may be much lower performance than desirable, however, it means that we don't lock people into using large-vendor chipsets which have unknown, or known to be bad, security properties such as Intel AMT.

In general, targeting open hardware seems to me to be more critical than performance metrics for the long term health of Bitcoin, however, performance is still important.

Does anyone know how the RISC-V FPGA performance stacks up to, say, a Raspberry Pi?

I'm also a user who runs a full node, and I also like this idea. I think Gavin has done some back-of-the-envelope calculations around this stuff, but nothing so clearly defined as what you propose.

I think this is a great suggestion! I'd love to know what system
requirements are needed for running Bitcoin Core.
