Bitcoin defended the $30,000 support level as the market eagerly awaits the potential approval of a bitcoin ETF. BlackRock CEO Larry Fink’s endorsement of bitcoin has divided analysts, with some concerned about the potential impact on decentralization. Meanwhile, dYdX Foundation CEO Charles d’Haussy discussed the platform’s move away from Ethereum to its own blockchain on Cosmos. He emphasized the importance of tech sovereignty and the ability to control the platform’s technology stack. dYdX’s blockchain is designed for its specific use cases but will be open for other platforms to build on. D’Haussy sees this move as part of a broader trend where crypto applications are optimizing for specific purposes rather than relying on general-purpose blockchains. He also highlighted the importance of diversity among validators to prevent centralized failure. In the coming years, he predicts that regulations may require financial institutions to access public networks via domestic nodes.
