I am wondering if the first two roundtrips of pre-committing and then revealing R/r in MuSig signing can be moved to the keygen phase and made deterministic. That reduces the amount of messages that need to be exchanged, since keygen is done only once and we want to expand that phase. This would be especially useful for HD wallets so that at the expense of making wallet creation more complicated, signing needs fewer interactions.

The [musig paper](https://eprint.iacr.org/2018/068.pdf) on page 11, "Signing" specifies that signer 1:

1. sends t<sub>1</sub>=H<sub>com</sub>(R<sub>1</sub>)
2. receives t<sub>i</sub> 
3. sends R<sub>1</sub>
4. receives R<sub>i</sub>
5. checks that H<sub>com</sub>(R<sub>i</sub>)==t<sub>i</sub>

YOU NEED TO ADJUST PATHS IN THE TWO FOLLOWING SCRIPTS!!!

You need
- expect(1), package expect on Ubuntu
- bitcoind/bitcoin-cli 0.16 (with wallet. tested with 686e97a0c) in $PATH
- lnd (tested with 26f68da5b2883885fcf6a8e79b3fc9bb12cc9eef)
- electrum on lightning
- electrumx
- jq ('lightweight and flexible command-line JSON processor')
