# Join the BitSong Network Public Testnet

TIP

See the networks repo for information on the testnet, including the correct version of the go-bitsong to use and details about the genesis file.

WARNING

You need to install go-bitsong before you go further

# Setting Up a New Node

These instructions are for setting up a brand new full node from scratch.

First, initialize the node and create the necessary config files:

bitsongd init <your_custom_moniker> --chain-id=bitsong-testnet-3

Note

Monikers can contain only ASCII characters. Using Unicode characters will render your node unreachable.

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

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

You can edit the ~/.bitsongd/config/app.toml file in order 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

##### main base config options #####

# The minimum gas prices a validator is willing to accept for processing a
# transaction. A transaction's fees must meet the minimum of any denomination
# specified in this config (e.g. 10ubtsg).

minimum-gas-prices = ""

Your full node has been initialized!

# Genesis & Seeds

# Copy the Genesis File

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

mkdir -p $HOME/.bitsongd/config
curl https://raw.githubusercontent.com/bitsongofficial/networks/master/bitsong-testnet-3/genesis.json > $HOME/.bitsongd/config/genesis.json

Note we use the latest directory in the bitsong-testnet-3 repo which contains details for the testnet like the latest version and the genesis file.

To verify the correctness of the configuration run:

bitsongd start

# Add Seed Nodes

Your node needs to know how to find peers. You'll need to add healthy seed nodes to $HOME/.bitsongd/config/config.toml. The bitsong-testnet-3 repo repo contains links to some seed nodes.

You can also ask for peers on the Validators Discord Chat

For more information on seeds and peers, you can read this.

# A Note on Gas and Fees

WARNING

On BitSong Network, the accepted denom is ubtsg, where 1btsg = 1.000.000ubtsg

Transactions on the BitSong Network need to include a transaction fee in order to be processed. This fee pays for the gas required to run the transaction. The formula is the following:

fees = ceil(gas * gasPrices)

The gas is dependent on the transaction. Different transaction require different amount of gas. The gas amount for a transaction is calculated as it is being processed, but there is a way to estimate it beforehand by using the auto value for the gas flag. Of course, this only gives an estimate. You can adjust this estimate with the flag --gas-adjustment (default 1.0) if you want to be sure you provide enough gas for the transaction.

The gasPrice is the price of each unit of gas. Each validator sets a min-gas-price value, and will only include transactions that have a gasPrice greater than their min-gas-price.

The transaction fees are the product of gas and gasPrice. As a user, you have to input 2 out of 3. The higher the gasPrice/fees, the higher the chance that your transaction will get included in a block.

TIP

For mainnet, the recommended gas-prices is 0.025ubtsg.

# Set minimum-gas-prices

Your full-node keeps unconfirmed transactions in its mempool. In order to protect it from spam, it is better to set a minimum-gas-prices that the transaction must meet in order to be accepted in your node's mempool. This parameter can be set in the following file ~/.bitsongd/config/app.toml.

The initial recommended min-gas-prices is 0.025ubtsg, but you might want to change it later.

# Run a Full Node

Start the full node with this command:

bitsongd start

Check that everything is running smoothly:

bitsongcli status

View the status of the network with the BitSong Testnet Explorer.

# Export State

go-bitsong can dump the entire application state to a JSON file, which could be useful for manual analysis and can also be used as the genesis file of a new network.

Export state with:

bitsongd export > [filename].json

You can also export state from a particular height (at the end of processing the block of that height):

bitsongd export --height [height] > [filename].json

If you plan to start a new network from the exported state, export with the --for-zero-height flag:

bitsongd export --height [height] --for-zero-height > [filename].json

# Upgrade to Validator Node

You now have an active full node. What's the next step? You can upgrade your full node to become a BitSong Validator. The top 32 validators have the ability to propose new blocks to the BitSong Network. Continue onto the Validator Setup.
