The year 2025 will mark an important phase for Solana as Anza, the development team that split from Solana Labs, has just announced an upgrade roadmap aimed at optimizing performance and doubling blockspace capacity. Instead of launching a single breakthrough improvement, Anza chooses to pursue a path of accumulating numerous small enhancements, making the Solana blockchain increasingly robust and stable.


Micro-Advancements: Small but Decisive Steps


Anza, the client development unit of Agave (the native validation software of $SOL ), is making several small but necessary tweaks to the system. Anza's Vice President of Core Engineering, Brennan Watt, believes that:



"Complex systems cannot be optimized by a single magic solution, but through the accumulation of thousands of small improvements."



Some key updates in the 2025 roadmap include:



  • Improve Agave's scheduler to allocate resources more efficiently.

  • Expand Turbine, Solana's block propagation protocol, to increase transaction validation speed.


  • Switch to a faster hashing algorithm to enhance data security without slowing down the system.



Increase Block Limit – A Cautious Breakthrough


Currently, each block on Solana can contain up to 48 million Compute Units (CUs) - a unit of measurement for the network's computational capacity. According to Anza, this figure is becoming a barrier limiting Solana's bandwidth, preventing the network from scaling further.


Therefore, Anza proposes to increase the block limit to 50 million CUs. While this increase is not significant, it is a cautious step to ensure that network participants can handle the growing data volume without performance issues.


Challenges from the Read Layer


One of the biggest bottlenecks in scaling blocksize is the read layer – the component that converts blockchain data into a format readable by programs.


#SolanaFoundation also acknowledges that the read layer needs to be reformed, and improvements will be implemented this year. This is especially important as Solana gradually increases block capacity, necessitating a faster, more robust data reading system.


Conclusion


The 2025 roadmap of #solana not only focuses on expanding blockspace but also aims to fine-tune a multitude of technical factors to optimize network performance. These small but essential improvements could help Solana maintain its position as a top-performing blockchain in the industry.


With the emergence of Firedancer (a high-performance client currently being tested) and improvements from Anza, Solana may enter 2025 with a faster, stronger, and more stable blockchain architecture than ever before. #anhbacong
