# Mainnet

This document introduces how to join the mainnet of smartBCH as a normal node (non-validator node).

Before you start, you must have a trusted server running bitcoincashnode's client with RPC enabled. The executable `smartbchd` will connect to it for querying staking information.

First, build the latest binary by running the steps of [this document](https://github.com/smartbch/docs/blob/master/developers-guide/build-smartbchd.md).

Second, prepare the working directory:

```bash
cp ~/smart_bch/smartbch/smartbchd ~/build/smartbchd
cd ~
rm -rf .smartbchd
~/build/smartbchd init mynode --chain-id 0x2710
wget https://github.com/smartbch/artifacts/releases/download/v0.0.6/dot.smartbchd.tgz
tar zxvf dot.smartbchd.tgz
cp -rf dot.smartbchd/* .smartbchd/
```

Third, open the `~/.smartbchd/config/app.toml` file to modify the information of the bitcoincashnode's client with RPC enabled.

```
# BCH mainnet rpc url (Only BCHN & BCHD are well tested)
mainnet-rpc-url = "http://ip-address:8332"

# BCH mainnet rpc username
mainnet-rpc-username = "<my user name>"

# BCH mainnet rpc password
mainnet-rpc-password = "<my password>"
```

Last, start smartbchd.

```bash
cd ~/build
./smartbchd start --mainnet-genesis-height=698502
```

## Docker

You can also run your smartBCH node using Docker. First, clone smartBCH and build Docker image for mainnet (or [pull prebuilt images from DockerHub](https://hub.docker.com/r/smartbch/smartbchd/tags)):

```bash
git clone https://github.com/smartbch/smartbch.git
cd smartbch
docker image build -f Dockerfile.optimized -t smartbchd:latest .
```

Second, prepare smartBCH mainnet home directory:

```bash
cd somewhere
mkdir smartbchd_home
docker run \
  -v path/to/smartbchd_home:/root/.smartbchd \
  smartbchd:latest init mynode --chain-id 0x2710

wget https://github.com/smartbch/artifacts/releases/download/v0.0.6/dot.smartbchd.tgz
tar xvf dot.smartbchd.tgz
cp -rfv dot.smartbchd/* smartbchd_home/
```

Third, edit smartbchd\_home/config/app.toml, modify the information of the bitcoincashnode's client:

```toml
...
mainnet-rpc-url = "http://ip-address:8332" # BCH mainnet rpc url
mainnet-rpc-username = "<my user name>"    # BCH mainnet rpc username
mainnet-rpc-password = "<my password>"     # BCH mainnet rpc password
...
```

Last, start smartbchd using Docker like this:

```bash
docker run \
  -v path/to/smartbchd_home:/root/.smartbchd \
  -p 0.0.0.0:8545:8545 \
  -p 0.0.0.0:8546:8546 \
  -p 0.0.0.0:26656:26656 \
  --ulimit nofile=65535:65535 \
  --log-opt max-size=200m \
  -d smartbchd:latest start --mainnet-genesis-height=698502
```
