Anza, the developer shop spun out of Solana Labs, has unveiled its 2025 roadmap, which focuses on optimizing Solana's efficiency and doubling its blockspace. The roadmap highlights Anza's commitment to tackling numerous small improvements that will enhance transaction handling capabilities and performance. A significant change includes gradually raising Solana's block limit from 48 million to 50 million compute units (CUs) per block, which aims to address bandwidth constraints. Although increasing the block limit could pose challenges for the network, especially for the read layer that formats blockchain data for applications, the roadmap underlines a philosophy that complex systems require many micro-advancements rather than a single fix. Anza also aims to scale Turbine, Solana's block propagation protocol, and transition to a faster hashing algorithm. Overall, the focus on incremental improvements is expected to pave the way for a more efficient Solana, particularly as the Firedancer client rolls out more broadly.
