Need more clarity on setting up the workshop

[rrybarczyk]

Background

The README.md currently shows how to setup the block explorer aspect of the workshop (electrs and mempool.space). However there is a bit more to the setup than just these things.

Problem

The README.md does not clearly note that the Blockchain Explorer contents are for workshop setup and does not include useful details like:

• Required installs.
• Where to find the signet Genesis node/which bitcoin fork to run.
• The bitcoin.conf contents.

I also ran into an issue with the mempool.space docker-compose.yml CORE_RPC_HOST variable.

Solution

Create docs/setup.md to host a complete instruction set to setup the workshop.

This signet-genesis-node.sh was found in the ~/sv2-workshop on the SRI VM. Would be good to commit this:

#!/bin/bash

# Check if the environment variables are set
if [ -z "$BITCOIND" ] || [ -z "$BITCOIN_CLI" ] || [ -z "$BITCOIN_UTIL" ] || [ -z "$BITCOIN_DATA_DIR" ] || [ -z "$MINER" ]; then
  echo "Please make sure all environment variables (BITCOIND, BITCOIN_CLI, BITCOIN_UTIL, BITCOIN_DATA_DIR, MINER) are properly set. Exiting."
  exit 1
fi

# Check if the specific port is in use
if lsof -i :38332 | grep -q LISTEN; then
  echo "Port 38332 is already being used, which means there's probably a bitcoind already running in signet mode. Exiting."
  exit 1
fi

echo "This script is about to erase some contents of the provided BITCOIN_DATA_DIR. Do you want to continue? (yes/no)"
read -r user_input

if [ "$user_input" != "yes" ]; then
  echo "User did not consent. Exiting."
  exit 1
fi

rm -rf $BITCOIN_DATA_DIR/signet
rm -rf $BITCOIN_DATA_DIR/bitcoin.conf

To get the slides up and accessible at http://75.119.150.111:8888/html/sv2-workshop.html:

• Log into the SRI VPS
• Create a new tmux session
• cd ~/sv2-workshop
• Start the server: python -m http.server 8888

In the mempool.space README.md instructions, change:

docker-compose up

to

cd docker/
docker-compose up
