Solana Changelog: Transaction Capping, BigTable Fixes, and OpenBook Launch

Welcome back to the Solana Changelog, where we dive deep into the latest updates and developments in the Solana ecosystem. In this edition, we'll explore some significant changes and improvements that have been implemented in recent weeks. From transaction capping to BigTable fixes, and the exciting launch of OpenBook, there's a lot to cover. Let's dive in!

Transaction Capping: A New Approach to Compute Units

One of the most notable changes coming to Solana is the way the protocol handles compute units for transactions. This update is expected to be implemented in version 1.15 and represents a significant shift in how transaction priority is managed.

From Estimated to Requested Compute Units

Previously, Solana used estimated compute units to manage transaction priority and block inclusion. However, the new system will use requested compute units instead. This change affects how the protocol handles transactions, especially those with priority fees.

Jacob, one of the hosts, explains:

"Previously it was using like estimated compute units. So the basically the protocol was estimating the compute units used on your specific transaction and then using that in order to manage how many transactions make it into a block and kind of manage it against priority fees."

Default Compute Units

Under the new system, if a developer doesn't specify a compute limit, the default will be set to 200,000 compute units for a single instruction. This default value scales with the number of instructions in a transaction, up to a maximum of 1.4 million compute units.

Jacob clarifies:

"Today that like the requested compute units when you ever use a compute budget program without using that and you have one instruction you're always gonna have 200 compute units requested and 200k and it will be 200k times the amount of instructions in your transaction with a maximum of 1.4 million."

Implications for Developers

This change has significant implications for developers, especially those working with priority fees. It's crucial for developers to understand how this new system works to optimize their transactions and manage costs effectively.

While this change doesn't necessarily mean users will be paying more, it does alter how the protocol interprets and prioritizes transactions. Developers who aren't actively managing their compute budgets may want to revisit their code to ensure they're not requesting more compute units than necessary.

Capping Account Data Loading in Transactions

Another important update is the introduction of a cap on the amount of account data that can be loaded in a single transaction. This change aims to prevent potential issues that could arise from loading excessive amounts of data in a single transaction.

The 100 Megabyte Limit

The new cap limits the total amount of account data that can be loaded for a single transaction to 100 megabytes. This applies regardless of whether a lookup table is being used or not.

Joe explains:

"So say you sent in a transaction and you added 23 accounts to load with that transaction and each of those accounts was 10 megabytes the maximum for each account. You can actually do that anymore the amount of data that can be loaded for a single transaction is now capped at a up to 100 megabytes amount."

Impact on Transaction Design

This change forces developers to be more mindful of the data they're loading with each transaction. It encourages more efficient transaction design and could potentially lead to improved overall network performance.

BigTable Fixes: Improving Node Stability

Solana nodes have been experiencing some disconnect issues with BigTable, the system used to store older block data. Recent changes have been implemented to address these problems, particularly focusing on token refresh.

Alleviating Disconnect Issues

The improvements to token refresh are expected to alleviate many of the disconnect problems that nodes have been experiencing. This should lead to more stable and reliable node operation, which is crucial for maintaining the health and efficiency of the Solana network.

Joe mentions:

"They've made some changes to the token refresh so that that's gonna probably be a little bit alleviated on that end. So that's kind of good if you're experiencing any issues with that. Hopefully that solves some problems."

Importance of Node Stability

Stable nodes are essential for the smooth operation of the Solana network. By addressing these BigTable issues, Solana is taking steps to ensure that nodes can maintain consistent connections and access to historical data, which is crucial for various network functions and applications built on Solana.

Versioned Transactions in Program Tests

A significant improvement for developers is the addition of support for versioned transactions within the program test framework. This update allows developers to more effectively test their code, particularly when working with address lookup tables.

Enhanced Testing Capabilities

With this new feature, developers can now create more comprehensive tests for their programs, especially those that utilize address lookup tables. This improvement in the testing framework will lead to more robust and reliable Solana programs.

Jacob emphasizes the importance of this update:

"That's definitely a big deal good to see that one."

Improving Developer Experience

By enabling versioned transactions in program tests, Solana is making it easier for developers to ensure the quality and reliability of their code. This improvement in the developer experience could lead to higher quality applications and increased developer adoption of the Solana platform.

Rust Client Improvements

The Solana team has also made improvements to the Rust client, specifically addressing issues with the get_program_accounts function. This update fixes parsing problems related to account context and additional parameters that were recently added.

Expanding Functionality

These improvements to the Rust client expand its functionality and reliability. Developers using the Rust client for Solana development will now have access to more robust and comprehensive account data retrieval capabilities.

Joe notes:

"They also did some rust clients of two like there was a problem with get program accounts that they fixed. It was like wasn't able to I think parse some kind of like account context or whatever kind of like additional parameters that have recently been added."

Importance of Client Libraries

Reliable and feature-rich client libraries are crucial for blockchain development. By continually improving and expanding the capabilities of the Rust client, Solana is making it easier for developers to build complex and efficient applications on the platform.

Token2022 Updates: Laying Groundwork for Confidential Transfers

The Solana team has been working on updates to the Token2022 program, laying the foundation for exciting new features like confidential transfers. These changes represent a significant step forward in Solana's capabilities and potential use cases.

Confidential Transfers

While not yet available on mainnet, the groundwork for confidential transfers is being laid in the Token2022 program. This feature could potentially enable more private and secure token transfers on the Solana network.

Joe mentions:

"I also saw some changes to token 2022. I think there was it actually like a patch upgrade. It looked like they were sort of laying down some of the frame like the groundwork for some of the like the confidential transfers that were talked about like kind of tease to us a little bit."

CPI Guard

Another addition to the Token2022 program is the CPI (Cross-Program Invocation) Guard. While the exact details of this feature weren't fully explained in the podcast, it appears to be a mechanism for protecting against certain types of CPI-related vulnerabilities or attacks.

Joe speculates:

"There's something called a CPI guard that they added as well which like at first glance kind of seems like it's protecting against like or at least enabling protection against CPI."

Future Developments

These updates to Token2022 hint at exciting future developments for Solana. The addition of features like confidential transfers could open up new use cases and attract more users and developers to the platform.

Jacob adds:

"The confidential transfers are starting to like more be built out right now. Mainly because there's a lot of they've recently enabled the ability to test with larger transactions which was a requirement to run confidential transfers."
