Solana's Latest Developments: RPC Changes, Actions, and Blinks

In the fast-paced world of blockchain technology, Solana continues to evolve and improve its ecosystem. The latest Solana Changelog, hosted by Nick Frostbutter from the Solana Foundation and featuring Jonas, offers insights into recent developments, upcoming changes, and exciting new features. This article delves into the key topics discussed, providing a comprehensive overview of Solana's latest advancements.

SIMD-148: Enhancing Stake Management

One of the significant improvements highlighted in the changelog is SIMD-148, which focuses on enhancing stake management within the Solana ecosystem. This improvement document, recently approved, introduces new instructions for moving stake and lamports between different staking accounts.

Benefits for Stake Pool Providers

The changes introduced by SIMD-148 are particularly beneficial for stake pool providers. Jonas explains, "This is especially interesting for stake pool providers. So you can easily get a bunch of stake delegated and they can take parts of it to different validators." This enhancement allows for more fluid movement of stake without the need to unstake and restake, streamlining the process for managing large pools of delegated stake.

Addressing Previous Concerns

While these changes offer significant improvements in stake management, there were previous concerns about potential issues if slashing were to be implemented in the future. However, the benefits of easier stake movement appear to outweigh these theoretical concerns for now. Jonas notes, "In the meantime, this will make it way easier to move stake around and you don't need to un-stake it and stake it again."

Removal of Deprecated RPC Methods in Version 2.0

A critical update discussed in the changelog is the removal of deprecated RPC (Remote Procedure Call) methods in the upcoming Solana version 2.0. This change is part of Solana's ongoing efforts to streamline its codebase and improve overall efficiency.

Impact on Developers

Nick emphasizes the importance of this update for developers: "Now that version 2.0 of the Agabe runtime, the Agabe validator, the version has been cut, there's this PR that is actually going to start removing some of those deprecated RPC endpoints." This change will affect both the Solana validator and the Web3.js library, two core components of the Solana development ecosystem.

Transition to New RPC Endpoints

Developers are strongly encouraged to review their code and ensure they are using the most up-to-date RPC endpoints. Jonas warns, "Since many people, of course, ignore deprecation warnings, I know that, like, it's just the code is like cutting them through, but have a deep look at these, like, probably you still might use confirm transaction or get recent block hash or so on."

List of Affected Endpoints

While the specific list of deprecated endpoints wasn't provided in the transcript, it's crucial for developers to consult the official Solana documentation and review any deprecation warnings in their code. Common endpoints that might be affected include methods for transaction confirmation and retrieving recent block hashes.

Upgrading Crates to Version 2.0

The changelog also touched on recent issues related to the upgrade of Solana crates to version 2.0. This upgrade initially caused some dependency problems, but quick action was taken to resolve these issues.

Fixing Dependency Issues

Jonas explains, "So this is related to this PR here, which broke some dependencies because many of the packages actually have, like, the smaller or equal 2.0. And yeah, this broke in the last days a bunch of dependencies, but this is now already fixed." The swift response from the Solana team, particularly John Cinco, ensured that these issues were resolved promptly.

Version Management

To address the dependency problems, some versions were yanked, and fixes were implemented. This quick resolution highlights the Solana team's commitment to maintaining a stable and reliable development environment for its community.

Changes to Compute Unit Charging

An interesting development discussed in the changelog relates to changes in how compute units are charged, particularly concerning the loading of account data.

New Feature Gate

Nick explains the upcoming change: "There's a feature gate that is open and it's going to basically make it so the amount of data that you're requesting, account data size that you're requesting, will actually affect your total compute usage within your transaction."

Impact on Transactions

This change is significant because it introduces a new factor in transaction cost calculation. Previously, loading large amounts of account data didn't significantly impact compute usage. However, with this new feature, transactions that request large amounts of account data may see increased compute costs.

Implications for Developers

Developers working on applications that frequently load large accounts or multiple accounts should be aware of this change. Nick advises, "Be sure to be watching out for that. And if you are requesting lots and lots of account sizes or a very large account size, then you might start to notice things in the future once this feature gate gets activated."

Introduction to Solana Actions and Blinks

One of the most exciting topics covered in the changelog is the introduction of Solana Actions and Blinks, a new feature set that promises to enhance user interaction with Solana transactions.

What are Solana Actions?

Solana Actions is a new framework that allows developers to create interactive transaction links that can be shared across various platforms. Nick explains, "The idea of links and actions is bringing transactions to the users where they're already at."

Current Implementation on X (Twitter)

At present, Solana Actions are primarily implemented on X (formerly Twitter). Nick notes, "Right now it is just limited to X.com, your Twitter feeds, your DMs on Twitter. It's fun fact, it does work in DMs, which is really cool."

Potential Use Cases

The potential applications for Solana Actions are vast. Nick outlines some possibilities: "You could think of sharing a link for a token swap, digital collectibles, donations for charity, voting on the downloads, all sorts of different powerful things directly to where people are."

Developer Resources

To support developers in leveraging this new feature, several resources have been made available:

1. Official documentation on solana.com
2. A video walkthrough for learning about Actions in 17 minutes
3. Example implementations
4. An "Awesome Blinks" repository on GitHub for community-contributed resources

Community Engagement

The Solana team is actively encouraging community participation in the development of Actions and Blinks. Nick mentions, "If anyone is building anything that is blinks are action related, open a PR to this awesome blinks repo."

Solana Game Jam and Hackathon

The changelog also touched on upcoming events in the Solana ecosystem, particularly focusing on gaming-related initiatives.

Upcoming Game Jam

Jonas mentions an ongoing game jam, which includes a track for blinks: "When you hear this, the game jam will actually be in full force already. And they will be a track for blinks as well, probably. So you can try to make a game with blinks."

In-Person Events

Several in-person game jam events are happening across the globe, including:

• Eastern Berlin
• Turkey
• Munich, Germany
• Berlin, Germany
