The first blockchain-powered bank has launched in Wyoming, United States. Called N3XT, the institution makes business-to-business payments instant and available 24/7. The platform, which is interoperable with stablecoins, utility tokens, and other digital assets, offers its clients the ability to program and automate payments. By combining programmability, auditability, and speed without sacrificing regulatory compliance, N3XT aims to make "money flow as easily as information."

On December 3, 2025, Ethereum activated the Fusaka upgrade, increasing the gas limit per block from 45 million to 150 million. This innovation promises higher throughput, reduced costs, and a better experience for Layer 2 solutions (L2s), which are at the heart of Ethereum's development strategy. The EIP-7594 (PeerDAS) proposal reduces bandwidth demand and increases the capacity of data packets (blobs). This enables L2s to publish their transactions at lower cost while avoiding overloading the main chain.

In its report dated December 4, 2025, the IMF scrutinizes stablecoins. The financial institution acknowledges the potential of stable cryptocurrencies to modernize payments and increase financial inclusion. However, the organization also sees in these assets, currently driven mainly by private companies, a risk of currency substitution and capital flows. Translation: banking institutions must catch up in this area to avoid missing out on this innovation.

Considering the shortcomings of the MiCA regulation, the European Commission wants to extend the powers of the European Securities and Markets Authority (ESMA). This proposal aims to centralize supervision of key cryptocurrency market infrastructures. Like the SEC in the United States, ESMA could act directly on crypto asset service providers (CASPs), trading platforms, and central counterparties. The measure, currently being negotiated in the European Parliament and Council, also plans to relax rules on distributed ledger technology (DLT) to foster innovation in the sector.

Nearly $4 billion in net outflows have been recorded by Bitcoin ETFs since mid-October. A period during which the price of BTC dropped by 35%, falling from a historic high of $126,000 to $80,000. Is panic sweeping through institutional investors? According to Amberdata analysts, this is not institutional capitulation but rather a more nuanced situation driven notably by the closure of arbitrage trades and concentrated outflows. 89.1% of BTC sales on spot ETFs were made by Grayscale, 21Shares, and Grayscale Mini."
