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.

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

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 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.

Ark Makes Its Mainnet Debut – Is Arkade the Perfect Bitcoin Layer 2?

At Baltic HoneyBadger 2025 in Riga, Arkade completed its first live demonstration on the Bitcoin mainnet. As the first implementation of the Ark protocol, this second-layer infrastructure aims to make Bitcoin programmable without touching its protocol or relying on the wrapped tokens that have long undermined competing solutions.
