Detailed Installation Guide for OPI on Ubuntu 22.04

Installing & Running bitcoind

sudo apt update
sudo apt install snapd
snap install bitcoin-core

## if you want to use a mounted media as chain folder:
snap connect bitcoin-core:removable-media

## create a folder for bitcoin chain
mkdir /mnt/HC_Volume/bitcoin_chain
## run bitcoind using the new folder
bitcoin-core.daemon -txindex=1 -datadir="/mnt/HC_Volume/bitcoin_chain" -rest

Installing PostgreSQL

1. First install and run postgresql binaries.

sudo apt update
sudo apt install postgresql postgresql-contrib
sudo systemctl start postgresql.service

2. (Optional), I'll usually mark postgres on hold since apt will try to auto update postgres which will restart its process and close all active connections.

sudo apt-mark hold postgresql postgresql-14 postgresql-client-14 postgresql-client-common postgresql-common postgresql-contrib

3. Set a password for postgresql user.

sudo -u postgres psql

ALTER USER postgres WITH PASSWORD '********';
\q

4. (Optional), if you want to connect to DB instance remotely (if postgres is not installed on your local PC) you need to configure pg_hba.conf file.

nano /etc/postgresql/14/main/pg_hba.conf

## add the following line to the end of the file, change ip_address_of_your_pc with real IP
hostssl all             all             <ip_address_of_your_pc>/32       scram-sha-256

To reload the new configuration:

sudo -u postgres psql

SELECT pg_reload_conf();
\q

5. (Optional), some configuration changes:

nano /etc/postgresql/14/main/postgresql.conf

listen_addresses = '*'
max_connections = 2000

sudo systemctl restart postgresql

Installing NodeJS

These steps are following the guide at here.

sudo apt-get update
sudo apt-get install -y ca-certificates curl gnupg
sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://deb.nodesource.com/gpgkey/nodesource-repo.gpg.key | sudo gpg --dearmor -o /etc/apt/keyrings/nodesource.gpg

NODE_MAJOR=20
echo "deb [signed-by=/etc/apt/keyrings/nodesource.gpg] https://deb.nodesource.com/node_$NODE_MAJOR.x nodistro main" | sudo tee /etc/apt/sources.list.d/nodesource.list

sudo apt-get update
sudo apt-get install nodejs -y

Installing Cargo & Rust

These steps are following the guide at here.

curl https://sh.rustup.rs -sSf | sh
source "$HOME/.cargo/env"

To update cargo & rust:

rustup update stable

Cloning the repository

git clone https://github.com/bestinslot-xyz/OPI.git

All next shell script groups assumes that you are in OPI folder cloned by above command.

Installing node modules

cd modules/main_index; npm install;
cd ../brc20_api; npm install;
cd ../bitmap_api; npm install;
cd ../pow20_api; npm install;
cd ../sns_api; npm install;

(Optional): Remove the following from modules/main_index/node_modules/bitcoinjs-lib/src/payments/p2tr.js

if (pubkey && pubkey.length) {
  if (!(0, ecc_lib_1.getEccLib)().isXOnlyPoint(pubkey))
    throw new TypeError('Invalid pubkey for p2tr');
}

Otherwise, it cannot decode some addresses such as 512057cd4cfa03f27f7b18c2fe45fe2c2e0f7b5ccb034af4dec098977c28562be7a2

Installing python libraries

1. If you don't have pip installed, start by installing pip. guide.

wget https://bootstrap.pypa.io/get-pip.py
python3 get-pip.py
rm get-pip.py

or

sudo apt install python3-pip

2. Install dependencies

python3 -m pip install python-dotenv;
python3 -m pip install psycopg2-binary;
python3 -m pip install json5;
python3 -m pip install stdiomask;
python3 -m pip install requests;

Build ord:

sudo apt install build-essential;
cd ord; cargo build --release;

Do not run ord binary directly. Main indexer will run ord periodically

Initialise .env configuration and databases

Run reset_init.py in each module folder (preferrably start from main_index) to initialise .env file, databases and set other necessary files.

(Optional) Restore from an online backup for faster initial sync

1. Install dependencies: (pbzip2 is optional but greatly impoves decompress speed)

sudo apt update
sudo apt install postgresql-client-common
sudo apt install postgresql-client-14
sudo apt install pbzip2

python3 -m pip install boto3
python3 -m pip install tqdm

2. Run restore.py

cd modules/;
python3 restore.py;

Run

Postgres will auto run on system start.
Bitcoind needs to be run with -txindex=1 flag before running main indexer.
Do not run ord binary directly. Main indexer will run ord periodically

Main Meta-Protocol Indexer

cd modules/main_index;
node index.js;

BRC-20 Indexer

cd modules/brc20_index;
python3 brc20_index.py;

BRC-20 API

This is an optional API and doesn't need to be run.

cd modules/brc20_api;
node api.js;

Bitmap Indexer

cd modules/bitmap_index;
python3 bitmap_index.py;

Bitmap API

This is an optional API and doesn't need to be run.

cd modules/bitmap_api;
node api.js;

SNS Indexer

cd modules/sns_index;
python3 sns_index.py;

SNS API

This is an optional API and doesn't need to be run.

cd modules/sns_api;
node api.js;

POW20 Indexer

cd modules/pow20_index;
python3 pow20_index.py;

POW20 API

This is an optional API and doesn't need to be run.

cd modules/pow20_api;
node api.js;

Update

• Stop all indexers and apis (preferably starting from main indexer but actually the order shouldn't matter)
• Update the repo (git pull)
• Recompile ord (cd ord; cargo build --release;)
• Re-run all indexers and apis
• If rebuild is needed, you can run restore.py for faster initial sync
