[Electrs][Elements] Show proofs in /address/<addr>/utxo

[tiero]

When calling the /utxo endpoint would be very useful to get also the corresponding rangeProof, surjectionProof and the nonce.

Right now the only way to unblind a list of inputs is to call for each unspent the tx/<:txid>/hex endpoint and get the proofs from the decoded raw tx.

Implemented in Blockstream/electrs@9398eac.

I initially also added this information to the main transaction json format, but I ended up dropping it because the proofs can get pretty big. I pushed this to a branch in case this becomes relevant.

Thanks! The utxo endpoint is all what i need.
Will make from this commit the updated amd64 and arm images for the Nigiri box.

@shesek I just built the from latest new-index commit and trying it, I don't see nonce, surjection_proof and range_proof as documented.

I only see noncecommitment compared to before. Am doing it wrong?

You can try with nigiri, the image has been pushed already. (if you have it already on your system do docker rmi vulpemventures/electrs-liquid vulpemventures/electrs before runnig nigiri start --liquid)
