Use Bitcoin on a Command Line Only System

For developers interested in exploring alternative cryptocurrencies like Ethereum, using a full node client can be an attractive option. However, traditional Bitcoin clients are not designed to work entirely in the command line interface (CLI). In this article, we explore the process of using a full Bitcoin client on a pure command line system, specifically using Amazon EC2.

Why use Bitcoin with CLI?

By using Bitcoin in the CLI, developers can:

• Test and develop: Test new features or tweak existing features without compromising security.

• Performance optimization: Run the entire node with lower overhead, which improves performance.

• Explore alternative cryptocurrencies: Try Ethereum as an alternative blockchain.

Qualifications

To use Bitcoin on the CLI system, you will need:

• Bitcoin source code: Get the latest Bitcoin source code from [

• EVM (Ethereum Virtual Machine): Install an EVM compatible virtual machine to use Ethereum in addition to Bitcoin.

• Amazon EC2: Create or choose an Amazon EC2 instance with sufficient resources (CPU, memory, disk space).

Step-by-step guide

Here is a step-by-step guide to using Bitcoin on the CLI:

1. Configure your environment

Clone Bitcoin source code
Git clone  Bitcoin
CD Bitcoin

Change to the cloned directory
CD Bitcoin

2. Turn on EVM (optional)

If you want to use Ethereum in addition to Bitcoin, turn on EVM:

Translate EVM (for Ethereum)
Do it yourself

3. Install CLI-based node manager

One popular option is [Bitcoin Node Manager]( This tool provides an easy way to run multiple nodes in a CLI environment.

Clone the Bitcoin Node Manager repository
Git clone  node-manager

Change to the cloned directory
cd node-manager

4. Run the main Bitcoin client

Now you can use the main Bitcoin client like this:

Compile and install the main Bitcoin client
do
sudo apt-get update and sudo apt-get install bitcoin-qt

Start the main Bitcoin client in CLI mode
./bitcoin --daemon-cli

5. Configure EVM (if using Ethereum)

If you want to use Ethereum in addition to Bitcoin, configure EVM by creating a new “.evm/contracts.json” file with your custom Create contract specifications:

{
"type": "contract",
"source": {
"@includes": ["
"version": "1.0"
},
"configs": [
{
"name": "mainnet",
"rpcUrl": "
"ethAccount": "0x…"
}
]
}

This config points to the Ethereum masternode (RPC URL) and configures a custom contract with an account (using the “ethAccount” field).

6. Run the Bitcoin client in CLI mode

Finally, run the Bitcoin client using the following command:

Compile and install a custom Bitcoin client
do
sudo apt-get update and sudo apt-get install Bitcoin-CLI

Start the main Bitcoin client in CLI mode
./bitcoin-cli --config=.evm/contracts.json --node-url=

With these instructions, you should be able to run a full Bitcoin client on a simple command line system using Amazon EC2. Please note that this installation may not provide the same level of security as using GUI mode.

Conclusion

Using Bitcoin only in a CLI system allows developers to test and optimize their cryptocurrency projects with less effort.
