This guide explains how to set up and run an OP_CAT Layer node. You can either run a node using pre-built binaries or Docker.

Option 1: Using Pre-built Binaries​

Prerequisites​

Ubuntu 22.04​

sudo apt update
sudo apt install -y libssl3 libevent-2.1-7 libboost-filesystem1.74.0 libboost-thread1.74.0 libboost-program-options1.74.0 libboost-chrono1.74.0 libdb5.3++ libzmq5 libsodium23 libminiupnpc17 libevent-pthreads-2.1-7 zlib1g

Ubuntu 24.04​

sudo apt update
sudo apt install -y libssl3 libevent-2.1-7t64 libboost-filesystem1.83.0 libboost-thread1.83.0 libboost-program-options1.83.0 libboost-chrono1.83.0 libdb5.3++ libzmq5 libsodium23 libminiupnpc17 libevent-pthreads-2.1-7t64 zlib1g

Download​

Download the latest release from: https://github.com/OPCAT-Labs/layer/releases/latest

Extract the archive:

tar -xzf opcatlayer-<version>-<platform>.tar.gz

Configuration​

Create the configuration file at ~/.bitcoin/bitcoin.conf:

testnet=1
daemon=1

rest=1
txindex=1

rpcuser=opcatlayer
rpcpassword=Awes0meLayer!
rpcbind=0.0.0.0
rpcallowip=0.0.0.0/0

Run the Node​

Start the node:

./bitcoind

Check node status:

./bitcoin-cli getblockchaininfo

Stop the Node​

./bitcoin-cli stop

Option 2: Using Docker​

Prerequisites​

  • Docker and Docker Compose installed

Quick Start​

Clone the release repository:

git clone https://github.com/OPCAT-Labs/layer-release.git
cd layer-release

Modify data/bitcoin.conf as needed, then start the node:

docker compose up -d

Check node status:

./cli.sh getblockchaininfo

Stop the node:

docker compose down
