What is Bitcoin Core and why install it on a Linux server?
Bitcoin Core is the open-source software that powers the Bitcoin network, serving as the reference implementation for the cryptocurrency. It is designed to facilitate the creation, validation, and transmission of transactions on the Bitcoin network. As a full node, Bitcoin Core downloads and maintains a complete copy of the blockchain, ensuring that every transaction is verified against the rules of the Bitcoin protocol. This independent verification is vital for preventing double-spending and maintaining the trustless nature of the network.
By running Bitcoin Core on your Linux server, you operate a full node that independently verifies all Bitcoin transactions and blocks. This participation is crucial for maintaining the integrity and security of the network.
Running your own node enhances privacy by allowing you to interact with the Bitcoin network without relying on third-party services, which can track your IP address and transactions. It gives you complete control over your wallet and funds, reducing the risks associated with centralized services. Moreover, a full node contributes to the decentralization of the network, improving its resilience against attacks and enhancing its overall efficiency.
While running a Bitcoin node requires significant storage space and bandwidth due to the large size of the blockchain, the benefits of increased security, privacy, and control make it a worthwhile investment for any serious Bitcoin user.
Solutie
Step 1: Update and Install Dependencies
Before installing Bitcoin Core, ensure your server is up to date and that you have the necessary dependencies installed. Run the following commands:
sudo apt update
sudo apt upgrade
sudo apt install wget software-properties-common
Step 2: Download Bitcoin Core
Visit the official Bitcoin Core website to download the latest version of the software. Use wget to download it directly to your server:
wget https://bitcoincore.org/bin/bitcoin-core-24.0/bitcoin-24.0-x86_64-linux-gnu.tar.gz
Make sure you replace the version with the latest one available.
Step 3: Extract the Archive
Once downloaded, extract the Bitcoin Core binaries:
tar -xzvf bitcoin-24.0-x86_64-linux-gnu.tar.gz
Step 4: Install Bitcoin Core
Move the extracted files to /usr/local/bin so you can easily run Bitcoin Core commands from anywhere in the terminal:
sudo install -m 0755 -o root -g root -t /usr/local/bin bitcoin-24.0/bin/*
Step 5: Create the Bitcoin Data Directory
Bitcoin Core will store the blockchain and its configuration files in a specific directory. Create this directory:
mkdir ~/.bitcoin
Step 6: Run Bitcoin Core
You can now run Bitcoin Core for the first time using the following command:
bitcoind -daemon
This starts Bitcoin Core in the background as a daemon process.
Step 7: Verify the Installation
Check if Bitcoin Core is running correctly by viewing the log file:
tail -f ~/.bitcoin/debug.log
This log file should show the synchronization process as Bitcoin Core starts downloading the blockchain.
