Data security is a crucial issue, especially in a digital world where hacking and privacy breaches are becoming increasingly prevalent. To ensure the protection of digital files, one of the most effective means is the use of hashing algorithms. These have the particularity of transforming any type of data into a unique digital fingerprint that preserves its integrity. In this article, we will explain how this fingerprint is calculated for a file. For this practical case, we will use SHA-256, the hashing algorithm used by the Bitcoin protocol. But first, let's explore the fundamentals of hashing in general, and SHA-256 in particular.

Bitcoin (BTC) has revolutionized the financial world by offering a decentralized alternative to traditional online transactions. Since its launch in 2009, it has attracted a large community of users and developers, but it has also faced debates on how to evolve and develop. To resolve these differences, some members of the community have chosen to fork the Bitcoin blockchain. What does this term refer to? What are the different types of forks and how do they work? What are the impacts for users and miners? Let’s explore the world of forks together to deepen our understanding of how Bitcoin operates.

Bitcoin Gold (BTG) is a cryptocurrency project that resulted from a hard fork of Bitcoin (BTC). It was created with the aim of making mining more accessible. Since its launch, this project has been adopted by several exchange platforms and crypto wallets. In this article, we will explore in detail the origins of BTG and how it works. We will also attempt to determine what the future holds for this digital asset, which has been gaining ground in the cryptocurrency market for several years.

Bitcoin Diamond (BCD) is one of the major blockchain projects that emerged following a hard fork of Bitcoin (BTC). It was designed with the aim of overcoming certain challenges faced by its predecessor. In this article, we will examine the history, functionality, and potential benefits of BCD. Finally, we will explore how Bitcoin Diamond could evolve and develop in the future within an increasingly competitive cryptocurrency market.

Bitcoin, with its decentralized architecture, has revolutionized the world of blockchain. However, its operation relies on considerable electricity consumption, raising questions about the sustainability of this system. This article explores the energy mechanisms of Bitcoin and examines the factors influencing its electricity consumption. It assesses the environmental consequences of Bitcoin's energy consumption and discusses potential solutions for a greener future.

Since its creation in 2009, Bitcoin (BTC) has faced scalability challenges and transaction fees. To address this, several hard forks have emerged, including Bitcoin Cash (BCH). This digital currency was born with the aim of improving scalability and transaction efficiency. Let's take a deep dive into the history of BCH, its advantages and disadvantages, as well as its potential uses and development prospects.

The Bitcoin blockchain is a distributed ledger technology that underpins the first and most iconic cryptocurrency: Bitcoin. Since its creation in 2009, it has sparked global interest, challenging our conception of money and transactions. With its growth, debates have intensified around its environmental impact and its ability to scale without compromising its principles of decentralization. This article reveals the mechanisms of the Bitcoin blockchain, clarifying its complex functioning and practical implications for users and society as a whole.

Victim of its success, the Bitcoin network faces congestion problems: cryptocurrency transactions take longer to be validated and fees are higher. It is in this context that Segwit came into being, bearing the improvement proposal number BIP141. This is a soft fork of Bitcoin that helps to address the scalability of the network. In addition to improving the performance of the ecosystem, this upgrade has also brought better security to transactions. But how does Segwit actually improve the BTC blockchain? We explain everything in this comprehensive guide.
