Ethereum researchers want to reduce the finality time of transactions from 16 to 4 minutes. Behind this technical improvement is a concrete economic issue: to allow transfer services to mobilize less capital while waiting for the final confirmation of operations. For now, the project is still under study and does not plan any deployment date.

Ken Griffin believes investors are "almost certainly" in an AI-related bubble. The founder of Citadel does not, however, question the technology itself. His concern is mainly about the amounts invested, the cost of GPUs, and the difficulty many companies have in turning their expenses into productivity gains. For him, a correction could eliminate many players while allowing the future giants of the sector to emerge.

The rise in bond yields in the euro area revives the debate on the "vicious circle" linking the health of banks to that of states. European institutions hold 4,300 billion euros in sovereign debt, but their capital reserves are stronger than during the crisis of the 2010s.
