What is Bitcoin Core?
Today, there are numerous crypto wallets available. Third-party developers created many of these wallets. However, there has been a dedicated wallet through Bitcoin software called the Bitcoin Core Client for users to store their Bitcoins since the inception of the blockchain and crypto concept.
Bitcoin Core is open-source software that serves as a Bitcoin network client. It was created by Satoshi Nakamoto, the pseudonymous creator of Bitcoin, and was first released in 2009. Bitcoin Core is used to send and receive Bitcoin and verify and participate in the Bitcoin network.
Bitcoin Core is a full node that downloads and stores the entire blockchain. This allows Bitcoin Core to verify all transactions on the network and to participate in consensus. However, there is a light version of Bitcoin Core.
If you do not need to download and store the entire blockchain, you can use a light client. Lightweight clients do not download the entire blockchain but only the portions required to verify transactions. Light clients are typically lighter and more efficient than full nodes, but they may require more security.
Bitcoin Core is an essential component of the Bitcoin network. It enables users to send and receive Bitcoin and contributes to network security by participating in consensus. Bitcoin Core is a useful tool for developers because it provides a reference implementation of the Bitcoin protocol.
The goal of Bitcoin Core is to create a decentralized digital currency that is not controlled by any government or financial institution. Bitcoin Core is intended to be safe, efficient, and simple to use. It is a powerful tool for sending and receiving Bitcoin that also helps to secure the Bitcoin network.
Getting Started with Bitcoin Core
Setting up Bitcoin Core is different from the way you set up other crypto wallets. This is because when you install Bitcoin Core into your computer, you automatically have a copy of the entire Bitcoin blockchain on your node. It could be more straightforward, but it’s worth the process.
However, the Bitcoin Core Client was initially only available for mobile devices recently. This is due to its significant data nature. Installing the entire blockchain on the computer consumes more than 500 GB of data, but the mobile version is only for the wallet. Please follow the guidelines or steps below to set up Bitcoin Core on mobile and desktop;
Setting Up on Desktop
- Download the Software: You must first download the software to begin your setup process. To download, go to the Bitcoin official website. Please ensure you are on the right website because many scammers have similarly cloned sites. Go to the “Wallets” page to begin your download when you are on the website. The application is available for Windows, MacOS and Linux operating systems. Choose the one compatible with your computer and download the software.
- Install the Software: After downloading the software, locate the file downloaded and click on it to begin the installation. Follow the onscreen instruction and wait for the installation to complete. When the installation is completed, wait some minutes for Bitcoin Core to download the entire history since 2009.
- Create a New Wallet: When the installation process is completed, and the software opens, click the “create wallet” button in the middle to create a new address. Next, input the name you want for the wallet and click the “create” button below your screen to continue. To complete the process, set up an alphanumeric password of not less than eight characters to secure your account.
After the last process above, the wallet will be created and available for use immediately.
Setting Up on Mobile
The Bitcoin Core mobile version wallet is called “Bitcoin Wallet”. It is lightweight and relatively straightforward to install and use, unlike the Desktop version. To use the mobile wallet, go to the respective app stores of your mobile device, search for “Bitcoin Wallet”, and install it. After installation, the app will be automatically available for use.
Important: Please ensure you back up your wallet. You can back up your wallet by creating your password and encrypting your wallet in a file. This file will be automatically saved to your device. Duplicate the file into a trusted mobile device or flash drive in case you lose your device.
Cryptocurrencies & Assets Supported by Bitcoin Core
At the time of writing, Bitcoin Core only supported Bitcoin. You must use a different wallet or client if you want to use other cryptocurrencies or assets. There are several wallets and clients that support various cryptocurrencies and assets.
Bitcoin Core Keys and Security
To secure user funds, Bitcoin Core employs a system of public and private keys. Bitcoin is received using public keys, and it is spent using private keys. Private keys are generated and are never made public.
When you create a Bitcoin Core wallet, you are given a generated private key and a corresponding public key. The public key is basically used to create a Bitcoin address, a string of characters that can be used to send Bitcoin to your wallet.
When you spend Bitcoin, you sign the transaction with your private key. This signature proves that you are the owner of the Bitcoin being spent. The network verifies the signature, and the transaction is added to the blockchain.
It is very important or crucial to keep your private key safe. If your private key is stolen, you will lose access to your Bitcoin. There is no other way to recover a lost or stolen private key. Follow the steps below to view your private keys in Bitcoin Core;
- Open Bitcoin Core.
- Click on the “Help” menu.
- Select “Debug Window”.
- Select the “Console” tab.
- Type the following command: dumpprivkey <address>
- Replace the address above with the public address of your wallet and click “enter”. Bitcoin Core will display the private keys of your wallet address.
Other Bitcoin Core Features
Bitcoin Core Client is not just a Bitcoin Wallet. The application has other unique features that make it special. The following are some of its other features;
A full node is like a diligent guardian, a watchful eye overseeing the entire Bitcoin network. When you run Bitcoin Core as a full node, you become an integral part of the decentralised ecosystem that powers Bitcoin. It’s like becoming a member of a vibrant and borderless digital community.
Bitcoin Core, as a full node, downloads and keeps a complete copy of the blockchain, the public ledger that records all Bitcoin transactions. This means you can see every transaction made on the network since the first block. It’s like having the entire Bitcoin history at your fingertips.
Being a full node means more than just having a complete copy of the blockchain. It also means actively participating in the validation and verification of transactions. When a new transaction is made or broadcasted on the network, your Bitcoin Core node verifies its authenticity by checking if it adheres to the rules of the Bitcoin protocol. It’s like being a guardian angel, ensuring that only legitimate transactions make it into the blockchain.
Bitcoin Core offers a command-line interface that puts you in direct control of the software through simple text-based commands. It’s like having a direct conversation with Bitcoin Core, where you can instruct it to perform various tasks and access its functionalities without needing a graphical user interface.
Using the command-line interface, you can perform a wide range of operations. For instance, you can query information about the Bitcoin blockchain, such as checking your account balance or the status of a specific transaction. You can initiate transactions, create new addresses, and even set up multi-signature wallets for added security. It’s like having a versatile toolbox, allowing you to shape your Bitcoin experience according to your needs.
The consensus protocol is an essential part of Bitcoin Core. It means that Bitcoin Core follows a set of rules defined by the Bitcoin protocol. These rules determine how transactions are checked and approved, how new blocks are created, and, ultimately, how everyone in the network agrees on the state of the blockchain. By sticking to these rules, Bitcoin Core ensures the blockchain remains secure and trustworthy.
Mining Support is a crucial aspect of Bitcoin Core that ignites the passion and dedication of its users. It grants them the power to become miners, heroes of the Bitcoin network, who tirelessly work to uncover new blocks and safeguard the entire ecosystem. However, it’s important to note that mining efficiency is a pursuit that demands fine-tuning. Dedicated miners often invest in specialised mining equipment and software tailored to this specific purpose to optimise their capabilities.
Privacy and Security
Bitcoin Core represents the actual value of Bitcoin and blockchain technology. At its core, Bitcoin Core upholds a fundamental principle that resonates with individuals seeking a sense of liberation from traditional financial institutions. It removes the barriers that have long restricted financial access, for it requires no personal information or the Know Your Customer (KYC) verification process. It allows users to transact without compromising their privacy, ensuring their details remain protected from prying eyes.
Bitcoin Core Usability and Support
Bitcoin Core is the Bitcoin protocol’s reference implementation. The entire blockchain is downloaded and validated by a full-node client. This makes it more secure than other wallets for storing Bitcoin, but it also makes it more difficult to set up and use.
The Bitcoin Core website contains a comprehensive guide on how to download and install and use the client. However, for new users, the process can be complicated and time-consuming. There is also a help section available. This section allows users ask questions and get help from other developers.
Bitcoin Core is a more powerful and secure wallet with more user-friendly features. If you want a simple and easy-to-use wallet, there are other options available.
