Communicate with bitcoin network via Electrum server(s)

[chill117]

• Use TCP sockets to communicate directly with electrumx (or electrum personal server) instances.

What the app needs:

• Get unspent transaction outputs (UTXO) for an address
• Get current network fee rate and minimum relay fee
• Broadcast raw transactions
• Watch an address for new transactions

My phone is connected over VPN to my DAppNode. Can we auto-detect that my.bitcoin.dnp.dappnode.eth domain is resolvable and try to use it as self-hosted node ? It would be really convenient.

@polto Is that a bitcoin full node or an electrum server? I've created a pull request (#346) that replaces the ct-api-server calls with direct communication to multiple electrum servers - includes automated peer management.

@chill117 for now DAppNode runs a Bitcoin and Ethereum full node. But DAppNode have a modular structure allowing people to deploy new DAppNode packages via IPFS and ENS. Lightning Network module exist for DAppNode , one could build a Electrum-server module, but it does not seems to exist yet.

Anyway it's already very cool to be able to connect to it's own electrum server.
