Solana Changelog: Validator Rewards, Snapshot Improvements, and Performance Optimizations

In the ever-evolving world of blockchain technology, Solana continues to make significant strides in improving its ecosystem. The latest Solana Changelog, featuring Nick from the Solana Foundation DevRel team and Jacob, delves into a range of exciting updates and developments that are set to enhance the Solana network's performance, governance, and developer experience.

Governance Proposal: Rewarding Full Priority Fees to Validators

One of the most noteworthy discussions in this changelog revolves around a governance proposal that aims to distribute all priority fees to validators responsible for packing blocks. This proposal is a continuation of a previously accepted idea and highlights the democratic nature of Solana's governance process.

The proposal, which is currently under a feature gate, requires a formal vote for implementation. As Jacob explains, "Part of the process for general changes on Solana is first you kind of talk about the idea, let's consider the idea stage within the SIMD process. Then you draft a SIMD, you get it reviewed, and then for some changes that affect economics, like this change, which is this is specifically SIMD 96 if you wanna read more about it."

This change, affecting the network's economics, necessitates a vote by validators based on stake weight. The proposal aims to reward validators with the full priority fees instead of burning half of them, potentially providing more incentives for validators to maintain the network's integrity.

SIMD-149: Migrating Snapshot Epoch Stakes

Another significant development discussed in the changelog is SIMD-149, which focuses on migrating snapshot epoch stakes. This improvement document addresses the need for versioning in snapshots and introduces a new field for epoch stakes.

Jacob elaborates, "The way this is that there's a current snapshot version that needs some changes, and this is kind of thinking ahead of like, 'Hey, if I ever need to make changes to the snapshot version or the snapshot structure, and we have multiple clients on the network, I need to be able to have versioning on it.'"

This update is crucial for maintaining compatibility across different clients on the network and ensuring smooth operations when rebooting from snapshots, especially during new rewards distribution periods.

Performance Optimizations: Reducing Replay Time and Improving Deserialization

The changelog highlights several performance improvements that have been merged into the Solana codebase. Nick commends Alessandro for his work on these optimizations, stating, "There were two big ones. This first one is a program cache, and basically the way that the runtime would actually write, it would do the right locks for some things that was less than ideal, it was less than optimal."

These improvements have resulted in a significant reduction in replay performance, with Nick noting, "With these new performance improvements that Alessandro's already merged in, it reduces replay performance by about 20 to 25%, which is pretty significant, it's pretty great."

Additionally, Alessandro has contributed to enhancing deserialization processes, further boosting overall performance. These optimizations are expected to benefit the entire validator set, improving the efficiency of the Solana network as a whole.

Load Balancing Improvements in the 118 Scheduler

The changelog also touches upon ongoing work to enhance the 118 scheduler's load balancing capabilities. Jacob explains, "Currently it has four threads to do all the work. In the new scheduler, it'll do four threads for like distributing and then they will make it in order in a single thread."

This improvement aims to optimize the distribution of compute units (CUs) across threads, potentially leading to more efficient transaction processing and better overall network performance.

Enhancing Robustness: Addressing Vote Program Panics

An interesting development highlighted in the changelog is a commit by Richie from FunNet Firedancer, addressing a non-security related crash in the VOTE program. Nick clarifies, "This is not a security bug. It's just a crash that happens whenever you do testing."

The fix prevents the program from panicking under specific states during testing. What's particularly noteworthy is that this issue was discovered through fuzz testing, showcasing the importance of comprehensive testing methodologies in maintaining the robustness of Solana's core components.

SolFuzz: A New Fuzz Testing Framework for Validators

The Firedancer team has introduced a new fuzz testing library called SolFuzz, which is designed to enhance the reliability and compatibility of Solana runtimes. Jacob explains the significance of this tool: "They've been using this within the Solana runtime to catch a bunch of different bugs and fix them so that they can, one, figure out bugs that might happen in the future, and two, make sure that they can test both multiple clients' runtimes at the same time."

SolFuzz allows developers to run test cases across different runtime implementations, ensuring consistency and identifying potential issues before they manifest in production environments. This tool represents a significant step forward in Solana's commitment to maintaining a robust and reliable blockchain infrastructure.

Create Solana DAP Update: Integrating Anchor 0.30

The changelog brings attention to an important update for Solana developers. The Create Solana DAP tool, which generates scaffolding for Solana applications, has been updated to use Anchor version 0.30.0 by default. Nick highlights the significance of this update: "When you use the Create Solana DAP CLI tool, generate a scaffold for your application, the anchor programs that get generated from that now use anchor 0.30 by default, and which means you can benefit from all of those ideal improvements that Acaran and the rest of the anchor team has been working so very hard about shipping those out."

This update streamlines the development process for new Solana applications, allowing developers to leverage the latest features and improvements in the Anchor framework right from the start of their projects.

Triton's Cascade: Improving Transaction Delivery

The changelog also mentions a new transaction delivery network called Cascade, developed by Triton. Jacob notes, "Brian Long has a post here on Twitter. He's created something called was a cascade that is a new transaction delivery network to kind of fix a lot of the outstanding issues around stake-weighted quality service."

Cascade aims to address challenges in transaction delivery, particularly focusing on improving the process of deploying programs. This development is part of ongoing efforts to enhance the overall user and developer experience on the Solana network.

Anchor i11n: Simplifying Instruction Introspection

Another developer-focused resource highlighted in the changelog is the Anchor i11n crate created by Dean McLittle. Jacob describes it as "basically a way for you to look at instructions that are within your transaction. It's a bunch of helper macros without having to run your own distillation."

This tool simplifies the process of instruction introspection, potentially saving developers time and effort in their projects. The hosts express enthusiasm for such community-driven developments, encouraging developers to share similar helpful tools and crates.

Stack Exchange Activity: Community Engagement in Problem-Solving

The changelog concludes with a shoutout to active contributors on the Solana Stack Exchange. Nick mentions, "We had the top of the list here is Drew, who I believe is on the TinyDancer team. And then we have Jimmy and Stevie is on there. Everyone's crushing on Stack Exchange this week."

This recognition highlights the vibrant and collaborative nature of the Solana developer community, where knowledge sharing and problem-solving are actively encouraged and celebrated.
