Xian Stack Quickstart

This guide will get you up and running with the Xian blockchain stack as quickly as possible. For advanced details, see the Reference section at the end.

---

1. Prerequisites

1.1 Install Docker & Docker Compose

• Mac: Docker Desktop for Mac
• Linux: Docker Engine and Docker Compose

Note: Docker Desktop (Mac) includes Docker Compose. On Linux, install Docker Compose separately after Docker Engine.

1.2 Clone the Repositories

make setup CORE_BRANCH=mainnet CONTRACTING_BRANCH=mainnet

This will pull all required Xian repositories.

---

2. Running a Xian Node (Core Only)

2.1 Build the Environment

make core-build

2.2 Start the Node Docker Container

make core-up

2.3 Initialize cometbft

make init

2.4 Configure the Node

make configure CONFIGURE_ARGS='--moniker "<your node name>" --genesis-file-name "genesis-mainnet.json" --validator-privkey "<your validator privatekey>" --seed-node-address "c3861ffd16cf6708aef6683d3d0471b6dedb3116@152.53.18.220" --copy-genesis'

2.5 Enter the Core Shell

make core-shell

2.6 Start the node

make up

2.7 View the logs to ensure the node is running

pm2 logs --lines 1000

2.8 Exit the Core Shell (the node will continue to run in the background)

exit

2.9 Stop the Node

make core-down

---

3. Running a Node with Blockchain Data Service (BDS)

3.1 Build the Environment

make core-bds-build

3.2 Start the Node Docker Container with BDS

make core-bds-up

3.3 Initialize cometbft

make init

3.4 Configure the Node

make configure CONFIGURE_ARGS='--moniker "<your node name>" --genesis-file-name "genesis-mainnet.json" --validator-privkey "<your validator privatekey>" --seed-node-address "c3861ffd16cf6708aef6683d3d0471b6dedb3116@152.53.18.220" --copy-genesis --service-node'

3.5 Enter the BDS Shell

make core-bds-shell

3.6 Start the node

make up-bds

3.7 View the logs to ensure the node is running

pm2 logs --lines 1000

3.8 Exit the BDS Shell (the node will continue to run in the background)

exit

3.9 Stop the Node

make core-bds-down

---

4. Running a Node in Development Mode (Core Dev)

4.1 Build the Dev Environment

make core-dev-build

4.2 Start the Dev Node Docker Container

make core-dev-up

4.3 Initialize cometbft

make init

4.4 Configure the Node

make configure CONFIGURE_ARGS='--moniker "<your node name>" --genesis-file-name "genesis-mainnet.json" --validator-privkey "<your validator privatekey>" --seed-node-address "c3861ffd16cf6708aef6683d3d0471b6dedb3116@152.53.18.220" --copy-genesis --service-node'

4.5 Enter the Dev Shell

make core-dev-shell

4.6 Start the node

make up

4.7 View the logs to ensure the node is running

pm2 logs --lines 1000

4.8 Exit the Dev Shell (the node will continue to run in the background)

exit

4.9 Stop the Node

make core-dev-down

---

5. Contracting Development Quickstart

5.1 Clone Contracting (if not already done)

git clone https://github.com/xian-network/contracting
cd contracting
# (Optional) Create a new feature branch
# git checkout -b <new-branch-name>

5.2 Build the Contracting Dev Environment

make contracting-dev-build

5.3 Start the Contracting Dev Shell

make contracting-dev-up

5.4 Run Contracting Unit Tests

pytest contracting/

5.5 Exit the Shell

exit

---

6. Running Tests for Core

6.1 Enter the Core Dev Shell

make core-dev-shell

6.2 Run Core Tests

pytest xian-core/tests/

6.3 Exit the Shell

exit

---

7. Useful Makefile Shortcuts

Action	Command
Start node (core only)	make core-up
Start node with BDS	make core-bds-up
Start dev environment with BDS	make core-dev-up
Stop node	make down
Stop container	make core-dev-down

---

8. (Optional) Firewall Configuration (Linux Only)

If you are running on Ubuntu/Debian, you may want to secure your node with UFW:

sudo apt install ufw
sudo ufw default deny incoming
sudo ufw default allow outgoing
sudo ufw allow 22/tcp comment 'SSH'
sudo ufw allow 26656/tcp comment 'Tendermint P2P'
sudo ufw allow 26657/tcp comment 'Tendermint RPC'
sudo ufw allow 26660/tcp comment 'Tendermint Prometheus'
sudo ufw allow 80/tcp comment 'HTTP'
sudo ufw allow 443/tcp comment 'HTTPS'
sudo ufw enable
sudo ufw status numbered

Warning: Always allow SSH before enabling UFW to avoid locking yourself out.

---

9. Troubleshooting

• Docker permission errors: Try running with sudo or add your user to the docker group.
• Ports already in use: Make sure no other services are using the required ports (26656, 26657, 26660, 5000).
• Containers not starting: Run docker-compose ps or docker ps to check status. Use docker-compose logs for details.
• Database connection issues: Ensure the xian-db network is running and not blocked by firewall.

---

Reference

Docker Networking

• xian-net: Main network for service communication and internet access. Exposes ports 26657, 26656, 26660, 5000.
• xian-db: Isolated network for database access (PostgreSQL only accessible within this network).

Docker Compose File Combinations

• docker-compose-core.yml: Base config for Xian node
• docker-compose-core-dev.yml: Adds dev settings
• docker-compose-core-bds.yml: Adds BDS with PostgreSQL

Combine with -f flag, e.g.:

docker-compose -f docker-compose-core.yml -f docker-compose-core-bds.yml up

Makefile Shortcuts (Reference)

• make up — Start node without BDS
• make up-bds — Start node with BDS
• make core-up — Start node (core only)
• make core-bds-up — Start node with BDS
• make core-dev-up — Start dev environment with BDS
• make down — Stop node
• make core-dev-down — Stop container

Advanced: Initializing CometBFT

If you need to initialize CometBFT manually:

make core-dev-shell
make init
