On this page Instruction on how to setup Bitcoin Regtest node alongside Ordinals node, and how to perform brc-20 tx inscription and execution.

​
Setup​

​
Bitcoin Regtest Node​

  1. Download the binaries, extract to the bin folder
wget https://bitcoincore.org/bin/bitcoin-core-25.0/bitcoin-25.0-x86_64-linux-gnu.tar.gz
tar -xzvf bitcoin-25.0-x86_64-linux-gnu.tar.gz
mv bitcoin-25.0/bin/* ~/bin/

rm -rf bitcoin-25.0  bitcoin-25.0-x86_64-linux-gnu.tar.gz
  1. Create home dir for bitcoin
mkdir ~/.bitcoin
  1. Initialize configuration file at ~/.bitcoin/bitcoin.conf
daemon=1
server=1
regtest=1
listen=1
txindex=1
rpcconnect=127.0.0.1
rpcuser=bitcoinrpc
rpcpassword=pass
  1. Start the node
bitcoind
  1. Verify the node is working
bitcoin-cli getblockcount

​
Ord Node​

Prerequisites:
  • Rust 1.78+
  1. Clone the Ord repo
git clone https://github.com/ordinals/ord.git
  1. Build the ord binary
cargo build --release
Built binary will be located at {project_root}/target/release/ord
  1. Create config file for the ord server ord.yaml
bitcoin_data_dir: $HOME/.bitcoin/
bitcoin_rpc_password: CCwXB6IxXcYMlBd6w812yfmiahxYBnlR0KLlvMIjgOrGq9eqgj9WmdeTCSDVo4w9
bitcoin_rpc_url: http://localhost:18443
bitcoin_rpc_username: bitcoinrpc
chain: regtest
data_dir: $HOME/.ord/
first_inscription_height: 0
index: $HOME/.ord/index.redb
index_addresses: true
index_cache_size: 1000000000
index_runes: true
index_sats: true
index_spent_sats: true
index_transactions: true
server_password: foo
server_url: http://localhost:80
server_username: bar
  1. Start the ord node
ord --config ord.yaml server --decompress
  1. Create a wallet
ord --config ord.yaml wallet create
Save the provided mnemonic. Your wallet name by default is ord
  1. Create a BTC address for your wallet
ord --config ord.yaml wallet receive
Use this address in the next step
  1. Mine some tokens for your wallet
bitcoin-cli generatetoaddress 110 "{YOUR_ADDR}"

​
Execution​

Now we have everything ready to inscribe and execute brc-20 txs

​
Deploy BRC-20​

  1. Create a json file with a deploy message
{
    "p": "brc-20",
    "op": "deploy",
    "tick": "ordi",
    "max": "1000000",
    "lim": "1000",
    "dec": "18"
}
  1. Create a transaction with the inscription for your wallet
ord --config ../release/ord.yaml wallet inscribe --fee-rate 1 --file deploy.json
  1. Mine new block to include your tx
bitcoin-cli generatetoaddress 1 "{YOUR_ADDR}"

​
Mint BRC-20​

  1. Create a json file with a mint message
{
    "p": "brc-20",
    "op": "mint",
    "tick": "ordi",
    "amt": "1000"
}
  1. Create a transaction with the inscription for your wallet
ord --config ../release/ord.yaml wallet inscribe --fee-rate 1 --file mint.json
  1. Mine new block to include your tx
bitcoin-cli generatetoaddress 1 "{YOUR_ADDR}"

​
Transfer BRC-20​

  1. Create a json file with a transfer message
{
    "p": "brc-20",
    "op": "transfer",
    "tick": "ordi",
    "amt": "100"
}
  1. Create a transaction with the inscription for your wallet
ord --config ../release/ord.yaml wallet inscribe --fee-rate 1 --file transfer.json
  1. Mine new block to include your tx
bitcoin-cli generatetoaddress 1 "{YOUR_ADDR}"
