Initialize Node

The following instructions assume that you have already completed the following:

• Initial Setup
• Install Regen

Initialize Node

Create the configuration files and data directory by initializing the node. In the following command, replace [moniker] with a name of your choice.

For Regen Mainnet:

regen init [moniker] --chain-id regen-1

For Regen Testnet:

regen init [moniker] --chain-id regen-upgrade

Update Genesis

Update the genesis file.

For Regen Mainnet:

curl https://mainnet.regen.network:26657/genesis | jq .result.genesis > ~/.regen/config/genesis.json

For Regen Testnet:

We should use /genesis_chunk endpoint instead of /genesis because the genesis response is too large. /genesis_chunked endpoint will return data which is encoded in base64. Combining the outputs of all the chunks and base64 decoding then will produce the genesis file of the network.

#!/bin/bash

# Output file
output_file="genesis.json"
temp_file="genesis_temp.json"

# Start clean
> "$temp_file"

# Fetch first chunk to get total number of chunks
initial_response=$(curl -s "https://rpc-regen-upgrade.vitwit.com/genesis_chunked?chunk=0")

# Extract total number of chunks
total_chunks=$(echo "$initial_response" | jq -r '.result.total')
if [[ -z "$total_chunks" || "$total_chunks" == "null" ]]; then
  echo "Failed to retrieve total chunk count."
  exit 1
fi

echo "Total chunks to fetch: $total_chunks"

# Loop through all chunks
for ((i=0; i<total_chunks; i++)); do
  echo "Fetching chunk $i..."
  response=$(curl -s "https://rpc-regen-upgrade.vitwit.com/genesis_chunked?chunk=$i")
  chunk_data=$(echo "$response" | jq -r '.result.data')

  if [[ "$chunk_data" == "null" || -z "$chunk_data" ]]; then
    echo "Failed to retrieve chunk $i"
    exit 1
  fi

  # Decode the chunk and append to temp file
  echo "$chunk_data" | base64 --decode >> "$temp_file"
done

# Move the completed file to genesis.json
mv "$temp_file" "$output_file"

echo "Genesis file assembled successfully into $output_file"

Update Peers

Add a seed node for initial peer discovery.

For Regen Mainnet:

PERSISTENT_PEERS="c4460b52c34ad4f12168d05807e998bb8e8b4812@mainnet.regen.network:26656,aebb8431609cb126a977592446f5de252d8b7fa1@regen.rpc.vitwit.com:26656"
sed -i '/persistent_peers =/c\persistent_peers = "'"$PERSISTENT_PEERS"'"' ~/.regen/config/config.toml

For Regen Testnet:

PERSISTENT_PEERS="fc6cf74d3de04ab0a3836f5adf50968990f2c195@155.138.196.253:26656"
sed -i '/persistent_peers =/c\persistent_peers = "'"$PERSISTENT_PEERS"'"' ~/.regen/config/config.toml

TIP

Only one persistent peer is listed above. If you experience connectivity issues, check the Regen Testnet documentation or community channels for additional peers.

Start Node

The node is now ready to connect to the network:

regen start

Create a Validator

The next step will be to create a validator.

Using State Sync

Also, syncing from genesis will be a slow process. You may want to consider using state sync.
