Is Bitcoin (BTC) Really a Currency?

Is Bitcoin (BTC) Really a Currency?

Often labeled as “digital gold” or dismissed as a speculative asset, Bitcoin (BTC) is already used by many as a tool for payments, saving, and protection against inflation. But does that make it real money?
What is the Lightning Network of Bitcoin?

What is the Lightning Network of Bitcoin?

The Lightning Network is Bitcoin’s payment layer, enabling instant, low-cost transactions without compromising decentralization. Discover why it exists, how it solves Bitcoin’s scaling limits, and whether it is a viable long-term solution or just an intermediate step in Bitcoin’s evolving monetary infrastructure.
The Bitcoin Revolution in Iran

The Bitcoin Revolution in Iran

In this report, I explore the increasing use of Bitcoin by Iranians, a population facing economic challenges as well as censorship from their government and foreign powers. My goal is to depict how Bitcoin serves as a tool for protecting freedoms and preserving value in a complex economic and political context.

What is Citrea? The Bitcoin rollup powered by BitVM?

What is Citrea? The Bitcoin rollup powered by BitVM?

While Bitcoin still concentrates most of the liquidity in the crypto market, its use remains largely limited to value transfer and long-term holding. This contrasts with other ecosystems where on-chain financial applications have expanded significantly. It is within this context that Citrea emerges, aiming to make Bitcoin programmable without modifying its base protocol.
What is Rootstock? The Bitcoin sidechain for smart contracts

What is Rootstock? The Bitcoin sidechain for smart contracts

Bitcoin was designed as a monetary system, not as a programmable platform. Yet over the past few years, several solutions have attempted to extend its capabilities without modifying its core protocol. Rootstock fits into this trend: a sidechain aiming to bring smart contracts to the Bitcoin ecosystem.
What is the Liquid Network? Bitcoin’s private and scalable sidechain?

What is the Liquid Network? Bitcoin’s private and scalable sidechain?

Bitcoin was designed as a robust monetary system, but with intentionally limited capacity. To address these constraints, several solutions have emerged to improve its usability. Among them, the Liquid Network takes a different approach: a sidechain focused on speed, privacy, and asset issuance.
What are Ordinals, Runes, and other inscriptions on Bitcoin?

What are Ordinals, Runes, and other inscriptions on Bitcoin?

Since 2023, a new practice has emerged on Bitcoin: inscriptions. Images, text, tokens, and various files can now be recorded directly on the blockchain. Behind this shift, several protocols, Ordinals, BRC-20, and later Runes, have emerged in succession. Their appearance has expanded Bitcoin’s possible use cases while reigniting a long-standing debate about the network’s purpose.
What is BitVM? The protocol that enables Layer 2 rollups on Bitcoin

What is BitVM? The protocol that enables Layer 2 rollups on Bitcoin

Since its inception, Bitcoin has been designed as a simple, robust monetary system with intentionally limited programmability. Unlike blockchains such as Ethereum, it does not natively support complex smart contracts. Yet, the demand for more advanced applications on Bitcoin continues to grow, pushing developers to explore new approaches. This is where BitVM comes in.
What is the Spark protocol? A Bitcoin Layer 2 that simplifies BTC ownership, with significant trade-offs

What is the Spark protocol? A Bitcoin Layer 2 that simplifies BTC ownership, with significant trade-offs

Bitcoin was designed as a decentralized and verifiable monetary system, yet using it for fast and frequent payments remains complex. Second-layer solutions such as the Lightning Network have improved this usability, but at the cost of added technical complexity. The Spark protocol has a clear objective: simplify Bitcoin usage without relying on custodial intermediaries.
