Bitlight Local Development Environment

This is a local development environment for Bitlight. It is based on Docker and Docker Compose.

Prerequisites

Getting Started

Clone this repository
check the .env file and change the values if needed
Run make start or make up to start the development environment
Run curl localhost:3002 to see the Esplora API running
Run make test to run the tests
Open the http://localhost:5002 in your browser to see the Esplora UI

bitlight-local-env % curl -s localhost:3002/mempool | jq
{
  "count": 0,
  "vsize": 0,
  "total_fee": 0,
  "fee_histogram": []
}

For more information about the Esplora API, check the Esplora API documentation

Commands

make start - Start the development environment with full logs
make up - Start the development environment
make down - Stop the development environment
make restart - Restart the development environment
make clean - Remove all the containers and volumes
make recreate - Recreate the development environment
make logs - Show the logs of the development environment
make full-logs - Show the logs of the development environment with full logs
make cli or make core-cli - Run a bash shell inside the bitcoin-core container
make alice-cli - Run a bkd-cli repl inside the Alice Wallet container
make bob-cli - Run a bkd-cli repl inside the Bob Wallet container
make up-lnd - Start the LND containers: Alice, Bob
make down-lnd - Stop the LND containers
make start-docs - Start the documentation server, the docs is located in the docs folder

For manual run tests:

make activate - Get environment variables and activate them

Other commands are available, check the Makefile for more information

CLI Commands

Run make cli to enter the bitcoin-core container. The following commands are available:

Custom commands

In the bitcoin-core container, the following commands are available (they are just bash scripts in the docker/bitcoin/cli/bin folder):

load_wallet - Load the default minter wallet and show address and balance
mint <blocks_number> - Mint <blocks_number> blocks to the default wallet
send <address> <amount> - Send <amount> to <address> from the default wallet

The default wallet is wallet, and used for minting and sending BTC. You can create your own commands by adding a new bash script in the docker/bitcoin/cli/bin folder

Wallets

In Example, we have two wallets: Alice and Bob. You can use the following commands to interact with the wallets:

make alice-cli - Run a bkd-cli repl inside the Alice Wallet container
make bob-cli - Run a bkd-cli repl inside the Bob Wallet container

If you want to add new wallets,

you can refer to the docker-compose.yml file and add a new wallet service with service name wallet-<wallet_name>.
run make up to start the new wallet.
run make wallet-<wallet_name>-cli to enter the new wallet container.

Examples

Create A new wallet Alice and send 25 BTC to Alice's address

Run make alice-cli to enter the Alice Wallet container and chose the descriptor to start the REPL.

Please choose a descriptor to start the REPL:
 - (9) RGB Descriptor 9/*: tr(tprv8ZgxMBicQKsPeHzjP5LTL818LxwHbJNLZRa98Qdnn7M98fW15365cB1Sz9QZvYufASRKH6JEPhfpxVuFTKMHxDcEAVboqKuZdMmxzKVhMnW/86'/1'/0'/9/*)
 - (90) RGB Descriptor 9/0: tr(tprv8ZgxMBicQKsPeHzjP5LTL818LxwHbJNLZRa98Qdnn7M98fW15365cB1Sz9QZvYufASRKH6JEPhfpxVuFTKMHxDcEAVboqKuZdMmxzKVhMnW/86'/1'/0'/9/0)
 - (00) Bitcoin Descriptor 0/0: tr(tprv8ZgxMBicQKsPeHzjP5LTL818LxwHbJNLZRa98Qdnn7M98fW15365cB1Sz9QZvYufASRKH6JEPhfpxVuFTKMHxDcEAVboqKuZdMmxzKVhMnW/86'/1'/0'/0/0)
 - (*) quit
Enter your choice: 9 <== choose 9 for RGB Descriptor 9/*

Now, you can use the wallet object to interact with the wallet, for example:

wallet sync
wallet get_balance
wallet list_unspent
wallet get_new_address

The output should be similar to the following:

$ make alice-cli

>>

In the output, you can see the base information about the wallet, such as the XPUB, RGB Address, and Balance. Now you can use the wallet object to interact with the wallet, for example:

>> wallet sync 
{}
>> wallet get_balance
{
  "satoshi": {
    "confirmed": 0,
    "immature": 0,
    "trusted_pending": 0,
    "untrusted_pending": 0
  }
}

>> wallet get_new_address
{
  "address": "bcrt1pr3rupmav8a7av7dqfyvynu2wk02lduggnh9ln4ndze9aqvuv9y3sklwrss"   <== Alice's address used to receive BTC
}
>>

Remember the address bcrt1pr3rupmav8a7av7dqfyvynu2wk02lduggnh9ln4ndze9aqvuv9y3sklwrss for the next step. Now, let's send 25 BTC to Alice's address.

Open a new terminal and run make core-cli to enter the bitcoin-core container, and run following commands:

load_wallet
send bcrt1pr3rupmav8a7av7dqfyvynu2wk02lduggnh9ln4ndze9aqvuv9y3sklwrss 25
mint 1

The output should be similar to the following:

$ make core-cli 
docker compose -p bitlight-local-env exec -it -w /cli bitcoin-core /cli/active.sh
/cli $ load_wallet
load wallet's address: bcrt1qv6428v9lzk9ac5aswp4hlaf773r48824stfvx9 with balance: 50.00000000
/cli $ send bcrt1pr3rupmav8a7av7dqfyvynu2wk02lduggnh9ln4ndze9aqvuv9y3sklwrss 25
load wallet's address: bcrt1qx4mwpxpw0d8prsrw4fg8q2s94au6s2qk5dwc9g with balance: 50.00000000

Sent 25 to bcrt1pr3rupmav8a7av7dqfyvynu2wk02lduggnh9ln4ndze9aqvuv9y3sklwrss
/cli $ mint 1
load wallet's address: bcrt1q2rtzrwrlpjnknsct2re3ez595wx2c9ezmspacl with balance: 24.99996940

]
/cli $

Now, open http://localhost:5002/tx/recent in your browser, you should see the transaction with 25 BTC sent to Alice's address, open it, and you will see the transaction details.

Now, let's check the balance of Alice's wallet by running make alice-cli or go back to the previous terminal, and run the following commands:

wallet sync
wallet get_balance
wallet list_unspent

The output should be similar to the following:

$ make alice-cli
docker compose -p bitlight-local-env exec -it  wallet-alice /start-wallet.sh repl

    }
  }
