@proofrock I will rebase this after #38 is merged.

[proofrock]

Looks nice, thanks! Yes, let's rebase it after #38

[proofrock]

Thanks. There are still a couple of errors and conflicts, would you solve them (whenever you can)? Please try a "make test" afterwards.

./web_service.go:66:62: undefined: requestItemCrypto
./web_service.go:311:58: txItem.Decoder undefined (type requestItem has no field or method Decoder)

[proofrock]

Good code anyway, thanks! 👍

[thanhnguyen2187]

Oh yep I'm trying to rebase, but it seems simpler to create a new branch and copy the changes manually anyway 😅. I'll let you know when the new branch is ready

[thanhnguyen2187]

@proofrock it should be ready

[proofrock]

Many thanks!!

Next step is to write documentation for all that, but before I'd like to do the resultset format "change"
