Description

Setup an offline Electrs (Electrum Server) qube named "sys-electrs", connected to your own full node running on "sys-bitcoin" to index the blockchain to allow for efficient query of the history of arbitrary addresses.

A disposable qube "disp-electrs-builder" will be created, it will serve to install and verify Electrs. After the verification succeeds, files are copied to the template "tpl-sys-electrs". This method was chosen so the server can be always offline.

At least 200GB of disk space is required.

Installation

This formula depends on sys-bitcoin.

• Top:

sudo qubesctl top.enable sys-electrs
sudo qubesctl --targets=tpl-electrs-builder,tpl-sys-electrs,disp-electrs-builder,sys-electrs state.apply
sudo qubesctl top.disable sys-electrs

• State:

sudo qubesctl state.apply sys-electrs.create
sudo qubesctl --skip-dom0 --targets=tpl-electrs-builder state.apply sys-electrs.install-builder
sudo qubesctl --skip-dom0 --targets=tpl-sys-electrs state.apply sys-electrs.install
sudo qubesctl --skip-dom0 --targets=disp-electrs-builder state.apply sys-electrs.configure-builder
sudo qubesctl --skip-dom0 --targets=sys-electrs state.apply sys-electrs.configure

Usage

You may customize Electrs by writing to the file ~/.electrs/conf.d/electrs.conf.local.

If you are not using sys-bitcoin, you will need to add the RPC Authentication cookie to the qube sys-electrs in the file ~/.bitcoin/.cookie. Make sure there is no new line at the end of the cookie file, else Electrs will fail to start.
