Bull Bitcoin drags DAC8 before the Conseil d’État to have it canceled and draws a line in the sand

Bull Bitcoin announces that it has brought the French decree transposing DAC8 before the Conseil d’État, even though the company has just obtained its MiCA authorization. Behind this apparent paradox, Théo Mogenet, Managing Director of Bull Bitcoin Europe, defends a simple line. A Bitcoin platform can accept entering the European framework, without accepting that compliance becomes the systematic collection of sensitive data.

El Salvador, Bitcoin and Bukele: Audit of a Political Laboratory

In 2021, El Salvador became the first country to adopt Bitcoin as legal tender. Five years on, the balance sheet is contradictory: real security gains, an IMF deal that walked back the experiment, and a sovereignty narrative far simpler than the reality.

What is Spark? The Bitcoin Layer 2 behind the new wave of self-custodial wallets

Spark is a Bitcoin Layer 2 based on statechains and shared signing. It gives wallets a way to offer a Lightning-like payment experience without taking direct custody, but its self-custody guarantees are weaker than holding bitcoin directly on L1.

What is the Ark protocol? The missing piece to make Bitcoin a scalable everyday currency

Bitcoin is often described as a store of value, a form of “digital gold” meant to be held rather than spent. Yet, to function as a true monetary system, it must also enable payments that are fast, simple, and accessible. While solutions like the Lightning Network have significantly improved this aspect, they still introduce a level of complexity that limits adoption. It is in this context that the Ark protocol emerges.

What Is the Lightning Network? Bitcoin's Payment Layer Explained

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.

What Is Bitcoin? The Digital Currency Challenging Gold and Central Banks

Bitcoin is often treated as a speculative asset, but its purpose is more structural: to offer a scarce, verifiable digital currency without a central issuer. Here's how it works, what problem it solves, and why it matters beyond ETFs and exchanges.

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?

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 RGB, the ultra-scalable and highly confidential Bitcoin Layer 2?

Bitcoin was designed as a robust and decentralized monetary system, but its architecture naturally limits the complexity of applications built directly on its blockchain. For several years, different solutions have attempted to extend its capabilities without modifying its core rules. The RGB protocol follows this approach, with a radically different design: moving contract execution off-chain while preserving Bitcoin's security.

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.
