 Enhancing Block Optimization on the Solana Network: Strategies and Upcoming Changes


In the wake of unprecedented usage, the Solana network has been rigorously tested, highlighting the significance of block optimization. Despite maintaining stability, the network's components, notably priority fees and the transaction scheduler, have faced challenges. This article outlines immediate actions for developers and operators to enhance network performance and previews upcoming core protocol changes aimed at further optimization.

Immediate Actions to Improve Network Performance:

1. Implement Priority Fees:

   - Many Solana applications currently underutilize priority fees, leading to transaction delays or dropouts. Integrating dynamic priority fees into decentralized applications (dApps) is crucial for improving user experience.

   - The integration process is straightforward and can be accessed via the provided link.

   - Additionally, exchanges are encouraged to refer to the updated guide for calculating priority fees to streamline operations.

2. Optimize Program CU Usage:

   - Transactions on the Solana network consume compute units (CU) from the total available in a block, with a current cap of 48M CU.

   - To alleviate congestion, developers should strive to reduce the CU usage in their programs, thus allowing more transactions to be processed.

3. CU Budget Request Optimization:

   - Developers can specify a compute unit budget for transactions, with a default value set higher than necessary for most transactions.

   - Requesting excessive compute units upfront can lead to inefficient transaction scheduling. Developers are advised to request CU budgets that align closely with transaction requirements.

4. Use Stake-Weighted QoS:

   - Infrastructure providers are encouraged to adopt stake-weighted Quality of Service (QoS) as an additional sybil resistance mechanism.

   - Detailed guidance on stake-weighted QoS will be provided soon to facilitate its implementation.

Upcoming Core Protocol Changes in v1.18:

1. Transaction Scheduler Improvement:

   - The transaction scheduler, a critical component of the validator stack, is slated for enhancement in the v1.18 software release scheduled for mid-April.

   - The new scheduler implementation will be introduced alongside the current scheduler but will not be enabled by default, allowing validator operators to monitor its performance and revert to the old scheduler if necessary.


The Solana Foundation remains committed to optimizing the network's performance and will continue to provide updates to the community. For the latest information, users are encouraged to refer to the Solana Foundation's official channels.

By implementing these immediate actions and preparing for upcoming core protocol changes, developers and operators can contribute to the ongoing enhancement of block optimization on the Solana network, ensuring its resilience and efficiency in the face of increasing demand.
