Currently uses Monero addresses and binary names and so forth.

@Doy-lee will work on this issue.

[josephnicholas]

@Doy-lee some rpc-fields are not yet available in the current loki code. Should I directly merge them from Monero? An example is wide_cumulative_difficulty.

[jagerman]

No; wide_cumulative_difficulty is deliberately not merged (and probably won't be) because it is a pain to deal with, because we are nowhere even remotely close to the limits of a 64-bit int, and because there are better ways to handle it (for example, resetting it and/or rescaling difficulty values at some fork height).
