Solana developers are set to implement a significant core upgrade, potentially the largest in the blockchain's history. This redesign involves replacing the existing Proof of History and Tower BFT consensus mechanisms with a new system called Alpenglow, developed by Anza, a spinout from Solana Labs. This overhaul aims to enhance finality and responsiveness. Additionally, discussions around Ethereum include a proposal by co-founder Vitalik Buterin that introduces 'partially stateless nodes' aimed at reducing hardware requirements for running Ethereum nodes, thus promoting a more decentralized network. Meanwhile, Sam Altman's World Network announced a successful $135 million token sale to venture capital firms to facilitate network expansion. There are also updates regarding Solana's mobile initiative, with the Seeker phone launching soon and plans for a new SKR token. Overall, these developments reflect ongoing efforts to improve blockchain technology and user accessibility.
