Testing electrs

Install electrs

sudo apt-get update
sudo apt-get install librocksdb-dev wget
sudo apt-get install -qqy cargo clang cmake build-essential

From electrs git repo being tested:

ROCKSDB_INCLUDE_DIR=/usr/include
ROCKSDB_LIB_DIR=/usr/lib
cargo install --locked --path .
electrs --version

Install bitcoind

BITCOIND_VERSION=22.0

wget -q https://bitcoincore.org/bin/bitcoin-core-$BITCOIND_VERSION/bitcoin-$BITCOIND_VERSION-x86_64-linux-gnu.tar.gz
tar xvf bitcoin-$BITCOIND_VERSION-x86_64-linux-gnu.tar.gz
mv -v bitcoin-$BITCOIND_VERSION/bin/bitcoind .
mv -v bitcoin-$BITCOIND_VERSION/bin/bitcoin-cli .

Install electrum client

sudo apt-get install -qqy git libsecp256k1-0 python3-cryptography python3-setuptools python3-pip jq curl

git clone --recurse-submodules https://github.com/spesmilo/electrum/

python3 -m pip install -e electrum/

electrum version --offline

install electrumx server

git clone https://github.com/spesmilo/electrumx.git
cd electrumx
pip3 install .

Remove old data

rm -rf data/
mkdir -p data/{bitcoin1,bitcoin2,electrum,electrs,electrumx}

Start bitcoind node 1 and fund wallet

./bitcoind -version
./bitcoind -regtest -regtest -txindex=1 -datadir=data/bitcoin1 -printtoconsole=0 -fallbackfee=0.0001 &

Start and fund mining bitcoind node 2 and add to node 1

./bitcoind -regtest -txindex=1 -datadir=data/bitcoin2 -port=28444 -rpcport=28443 -printtoconsole=0 -fallbackfee=0.0001 &
BITCOIND2_PID=$!
