Solana is poised for a significant transformation as 98% of its community voted in favor of the 'Alpenglow' upgrade. This overhaul is expected to enhance the network's performance and scalability, marking a pivotal moment for the blockchain platform. Meanwhile, the Ethereum Foundation plans to sell an additional 10,000 ETH, continuing its strategy of liquidating portions of its holdings. In another development, Ethereum is set to close its largest testnet, signaling a shift in its testing and development approach.
