Join the Mainnet

We are moving our documentation to the new "BitSong, the blockchain for music" website. To access the most up-to-date and complete version of our guides and articles, please visit our new bitsong documentation website. This old documentation site will no longer be maintained or updated, so we strongly recommend referring to the new bitsong documentation website for the latest information. If you can't find what you're looking for on the new site, please be patient as we are still in the process of migrating all of our content. Thank you for your understanding! Visit the new article https://bitsong.io/en/docs/blockchain/join-the-mainnet

Make sure to have the latest go-bitsong version installed. First, initialize the node.

bitsongd init <your_custom_moniker>

Note Monikers can contain only ASCII characters. Using Unicode characters is not supported and renders your node unreachable.

By default, the init command creates your ~/.bitsongd directory with subfolders config and data. In the config directory, the most important files for configuration are app.toml and config.toml.

You can edit the moniker in the ~/.bitsongd/config/config.toml file:

# A custom human readable name for this node
moniker = "<your_custom_moniker>"

For optimized node performance, edit the ~/.bitsongd/config/app.toml file to enable the anti-spam mechanism and reject incoming transactions with less than the minimum gas prices:

# This is a TOML config file.
# For more information, see https://github.com/toml-lang/toml

# The minimum gas prices a validator is willing to accept for processing a

minimum-gas-prices = "0.0025ubtsg"

Your full node has been initialized!

Genesis & Seeds

Copy the Genesis File

Fetch the mainnet's genesis.json file into bitsongd's config directory.

wget -O ~/.bitsongd/config/genesis.json https://raw.githubusercontent.com/bitsongofficial/networks/master/bitsong-2b/genesis.json

Set persistent peers

Your node needs to know how to find peers. You'll need to add healthy seed nodes to $HOME/.bitsongd/config/config.toml

export PEERS="[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:31656,[email protected]:26656,[email protected]:26656,[email protected]:31656,[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:26256,[email protected]:31656,[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:31656"
sed -i.bak -e "s/^persistent_peers *=.*/persistent_peers = \"$PEERS\"/" ~/.bitsongd/config/config.toml

Synchronise the Node

Now we have to syncronise the node with the current state of the blockchain. The fastest way to achieve this is by using state sync, which we will use for this purpose.

sudo systemctl stop bitsong

SNAP_RPC="https://rpc.bitsong.forbole.com:443"
SNAP_RPC2="https://bitsong.stakesystems.io:2053"

LATEST_HEIGHT=$(curl -s $SNAP_RPC/block | jq -r .result.block.header.height); \
BLOCK_HEIGHT=$((LATEST_HEIGHT - 1000)); \
TRUST_HASH=$(curl -s "$SNAP_RPC/block?height=$BLOCK_HEIGHT" | jq -r .result.block_id.hash)

peers="[email protected]:26656,[email protected]:26656,[email protected]:16656,[email protected]:26656,[email protected]:31656,[email protected]:26656,[email protected]:26656,[email protected]:31656,[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:31656"

sed -i.bak -e "s/^persistent_peers *=.*/persistent_peers = \"$peers\"/" $HOME/.bitsongd/config/config.toml

sed -i.bak -E "s|^(enable[[:space:]]+=[[:space:]]+).*$|\1true| ; \
s|^(rpc_servers[[:space:]]+=[[:space:]]+).*$|\1\"$SNAP_RPC,$SNAP_RPC2\"| ; \
s|^(trust_height[[:space:]]+=[[:space:]]+).*$|\1$BLOCK_HEIGHT| ; \
s|^(trust_hash[[:space:]]+=[[:space:]]+).*$|\1\"$TRUST_HASH\"|" $HOME/.bitsongd/config/config.toml

cp $HOME/.bitsongd/data/priv_validator_state.json $HOME/.bitsongd/priv_validator_state.json.backup

bitsongd tendermint unsafe-reset-all --keep-addr-book --home "$HOME/.bitsongd"

mv $HOME/.bitsongd/priv_validator_state.json.backup $HOME/.bitsongd/data/priv_validator_state.json

sudo systemctl start bitsong

sudo journalctl -u bitsong -f

Enable the REST API

By default, the REST API is disabled. To enable the REST API, edit the ~/.bitsongd/config/app.toml file, and set enable to true in the [api] section.

###############################################################################
###                           API Configuration                             ###
###############################################################################

[api]

# Enable defines if the API server should be enabled.
enable = false

# Swagger defines if swagger documentation should automatically be registered.
swagger = false

# Address defines the API server to listen on.
address = "tcp://0.0.0.0:1317"

Optionally, you can activate swagger by setting swagger to true or change the port of the REST API in the parameter address. After restarting your application, you can access the REST API on YOURNODEIP:1317.

GRPC Configuration

By default, gRPC is enabled on port 9090. In the ~/.bitsongd/config/app.toml file, you can make changes in the gRPC section. To disable the gRPC endpoint, set enable to false. To change the port, use the address parameter.

###############################################################################
###                           gRPC Configuration                            ###
###############################################################################

[grpc]

# Enable defines if the gRPC server should be enabled.
enable = true

# Address defines the gRPC server address to bind to.
address = "0.0.0.0:9090"

Background Process

To run the node in a background process with automatic restarts, you can use a service manager like systemd. To set this up run the following:

sudo tee /etc/systemd/system/bitsongd.service > /dev/null <<EOF  
[Unit]
Description=BitSong Network Daemon
After=network-online.target

[Service]
User=$USER
ExecStart=$(which bitsongd) start
Restart=always
RestartSec=3
LimitNOFILE=4096

[Install]
WantedBy=multi-user.target
EOF

Then setup the daemon

sudo -S systemctl daemon-reload
sudo -S systemctl enable bitsongd

We can then start the process and confirm that it is running

sudo -S systemctl start bitsongd

sudo service bitsongd status
