How Bitcoin’s core enables the use of cryptocurrency on the market

Bitcoin is the first and most influential cryptocurrency. When it was released, the world was still recovering from an economic outburst, so for many, its existence meant accessing an innovative financial opportunity. Since there wasn’t any central institution to power it, people could perform borderless transactions with low fees, which made Bitcoin more appealing to the modern generation.

The cryptocurrency rapidly gained popularity and made it into the news, so the number of investors, miners, and validators boomed overnight. Acquiring it was more difficult back then, but you can now find the best places where to buy Bitcoin through various methods, including credit card, Google Pay, or P2P Trading.

Still, ensuring Bitcoin’s efficiency in the long term requires a lot of work and focus on maintaining its decentralized features. This proves to be more difficult as activities like staking on Ethereum risk becoming centralized. Therefore, those who collaborate to keep Bitcoin stable use the Bitcoin core to introduce new updates and fix vulnerabilities.

Here’s what’s the core about.

Core Bitcoin as a definitive protocol.

Behind the blockchain and cryptocurrency, the Bitcoin core is responsible for the software protocol that handles everything from mining and transactions to the verification process. The core has numerous implementations, as the original one covers more than 90% of the network, but the Bitcoin Knots or Bcoin protocols manage the rest.

Bitcoin Core operates the node, ensuring the network is safe and sound. Nodes here validate transactions and maintain a copy of the blockchain. Node operators are vital for the network because they:

Verify transactions, so there’s no need for third parties to be involved;
Secure the network and ensure decentralization is maintained;
Empower users by allowing them to have more control over their transactions;

In addition, the Bitcoin core provides specific functionalities for wallet technology, mining support, and block distribution across the blockchain.

How does Bitcoin guarantee continuous development?

While the Bitcoin core is mostly leveraged to maintain the network in good condition, its use cases also include innovation and development. Therefore, all updates the blockchain receives happen here. Developers, nodes, and validators work towards increasing the network’s efficiency, refining memory usage, and contributing to a user-friendly blockchain.

At the same time, upgrades are made so as not to compromise decentralization or security. New codes are easily introduced to the core as developers propose updates that are later reviewed and transformed into further developments. Anyone can use the Bitcoin core and modify or redistribute it, but no one owns the underlying code or special rights.

The process of accepting an update is called the Bitcoin Improvement Proposal (BIP) and includes reviewing, testing, and reaching a consensus on the network to make it up on the blockchain. Major updates usually occur twice a year, but maintenance releases might happen more often.

The evolution of the Bitcoin core

In the beginning, the Bitcoin core had 26,221 code lines, but they’ve expanded considerably since developers deleted or introduced new codes to make Bitcoin what it is today. The base code has everything nodes, miners, and participants need to work with the protocol, but the core has many other features, such as the following:

The dependencies include external tools for Bitcoin, such as a data storage library or a technology that generates public and private keys;
The localization takes up a considerable part of the codebase as it includes numerous translations, complete or partial, in different languages;
The tests are necessary to ensure that every code feature and codebase proposition is efficient on the blockchain;
The documentation area is where developers get all the information on the code so they can better contribute to its improvement;

Who can become a Bitcoin core developer?

Anyone can normally code on Bitcoin and contribute to the network. Of course, developers should have a solid knowledge base on decentralization, coding, and cryptocurrency. In addition, they must seek continuous learning as the industry is rapidly changing, so they need to add new information to what they already know.

Luckily, there are numerous web resources, such as the Bitcoin Development Mailing List or Chaincode Labs, that offer a complete picture of cryptocurrency and blockchain. Bitcoin meetups and events are available in most important cities, so there’s generally a lot happening in communities that contribute to its development.

Some of the skills people need to become developers include the following:

Blockchain architecture;
Programming languages like C++ and JavaScript;
Smart contracts;
Data structure;
Cybersecurity;
Web development;

Can Bitcoin and other blockchains coexist?

Although Bitcoin developers are working hard to promote safety and transparency, there’s always the risk of vulnerability in the systems, especially when talking about cross-chain bridges. These technologies ensure the possibility of assets from two different blockchains to be transferred, usually powered up by an application.

However, it might become inefficient to use cross-chain bridges due to security reasons, which is why a recent project started the idea of tunneling to unite the Bitcoin and Ethereum blockchains. The protocol is planned to secure Bitcoin interoperability and security while connecting to Ethereum, so users of the latter blockchain could benefit from Bitcoin-based asset tokenization.

In addition, the Ethereum creator is working on solving issues with cross-chain interoperability by proposing the “Fusion+” feature, through which users can leverage on-chain and off-chain liquidity for swaps powered by smart contracts. This could contribute to a seamless experience of tunneling between Bitcoin and Ethereum, building the bridges to a super network where there are no chances of attack vectors.

Bitcoin development is an integral part of the asset

The development of Bitcoin is a continuous process in which worldwide nodes and validators contribute to blockchain security and interoperability. The Bitcoin technology core allows anyone to tap in and suggest improvements, after which developers test and deliver updates. Becoming a Bitcoin developer isn’t that complicated, as you need basic programming languages. Still, the crypto and blockchain knowledge expands as we speak, so developers must be up-to-date with the latest technologies to advance Bitcoin’s usability.
