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?
