Later, we will aim to remove the Crdt Relayer from the architecture, by (a) moving to pure P2P transactions between Crdt Nodes, and (b) doing leader election of a Crdt Node to reach agreement on the submitted block.
## Bitcoin integration
There is a Bitcoin client integrated into the node, which can do simple coin transfers using esplora and the Mutinynet server's Signet (30 second blocktime).
The client's demo driver can be run by doing:
```
cargo run -- init dave
cargo run -- init sammy
cargo run -- btc
```
You'll need to have funded the "dave" address prior to running the `btc` command - otherwise the transfer will fail gracefully.
I was using this primarily as a way to experiment with constructing and broadcasting Bitcoin transactions, with the hope that it would be possible to move on to more advanced constructions (e.g. state channels). However, now that I look at all the options, it seems that multi-party state channels in Bitcoin are (probably) impossible to construct.
There is a second, unused Bitcoin client in place which uses Blockstream's Electrum server, but this didn't seem to be working properly with respect to Signet Bitcoin network during my testing, so I went with the esplora / Mutiny version instead.
