SBPFv3 is the bytecode format for Solana programs. This migration guide covers toolchain requirements, building with cargo-build-sbf, and the SIMD-0500 rules that reject deployments of older bytecode.

wincode is Anza's bincode-compatible Rust serializer, recommended by RustSec as a bincode replacement. Built for Solana, now used across the Rust community. Learn why we built it, how the design works, and how to run the benchmarks.

Quantumglow is a post-quantum adaptation of Alpenglow.

Kit v7 brings two major new features for developers building Solana apps.

Agave 4.0 is the latest major release shipping from the Anza team.

This is the first blog in a series of conversations with the engineers building the Agave validator client and the core programs that run on Solana. We're starting with Febo, the engineer behind Pinocchio and p-token.

Cryptographically relevant quantum computers are still several years away, but the Anza team and members of the Solana community have begun laying groundwork for what the quantum transition might look like.

Anza planned and executed a Devnet cluster halt on April 14, 2026. The purpose of the halt was to deactivate several abandoned features that were live on Devnet but not Mainnet-Beta.

The Constellation whitepaper, a protocol design for multiple concurrent proposers on Solana.

In this blog, we investigate slot latency and transaction drops.

Two critical potential security vulnerabilities were responsibly disclosed to Anza via GitHub security advisories in December 2025.

In this post, we share how Anza is entering a new chapter of leadership, reflect on a year of major performance and reliability wins for Solana, and outline what comes next.

In this article, we show how to enable XDP (eXpress Data Path) in Agave and why it matters for upcoming network upgrades.

Documentation is now available for Solana Kit, the evolution of the Solana JavaScript SDK, formerly named web3.js.

Clarifying the difference between compute units (CUs) and transaction cost, and how they relate to transaction fees on Solana.

Addressing the intricacies of market microstructures.

Agave 2.3 delivers a range of improvements across validator performance, developer tooling, and quality of life. This release features updates to snapshot handling, enhancements to the SBPF toolchain, and a revamped TPU client.

Meet Alpenglow: Solana’s new consensus protocol which highlights major performance gains. Learn more in the blog and linked white paper.

Detailing the advantages of bringing Scheduler Bindings to Agave.

This article outlines how multiple concurrent leaders will make decentralized NASDAQ a reality on Solana.

Details of the precompile alignment bug.

This article explores some of the key advancements that Agave has made over the last year and our roadmap for 2025.

Solana’s issuance plays a crucial role in network security and validator incentives, but is the current model optimal? This article explores the trade-offs of issuance, its impact on staking behavior, and a potential market-based alternative to improve efficiency.

This is the second article on the topic of the implementation of slashing in Solana which began with the introduction of SIMD-0204: Slashable Event Verification. Implementing slashing in Solana is a phased process involving the introduction of first a SIMD to log and monitor incidences of potentially slashable behavior followed by a second SIMD which involves specific economics and implementation of the slashing itself. In this article we will examine SIMD-0212: Slashing.

Many decentralized protocols make use of slashing as a mechanism to ensure correct behavior amongst validators. Solana has historically never had an automatic slashing mechanism, but that is set to change. This article outlines the first step in the process (SIMD-0204, a logger for bad behavior) followed by what to expect next.

Announcing the new Anza Research team!

Details of the web3.js exploit.

Timely Vote Credits (TVC) refers to a new feature designed and approved by Solana validator operators to incentivize validators to submit consensus votes in a timely manner. To do accomplish this goal, TVC will award extra vote "credits" to validators whose votes are included in blocks with relatively low latency. Earned vote credits are directly tied to the proportion of inflation rewards that are awarded to validators.

Anza's Invalidator Adversarial Team strengthens Solana's resilience by simulating real-world attack scenarios and stress-testing the network to identify vulnerabilities and ensure reliability.

With the introduction of Agave v1.18, a new instruction called setLoadedAccountsDataSizeLimit was added and carried forward into Agave v2.0+. This instruction provides developers with additional control over transaction prioritization and resource management within blocks. In this article, we will cover how developers can make use of this instruction as well as make use of it via Web3js.

Version 2.0.0 of the Solana JavaScript SDK (@solana/web3.js) has been released.

Solana programs must be executed according a very specific virtual machine instruction set architecture (ISA). This article provides an overview of that ISA, as well as a guided tour through the Agave validator's implementation and use of such a virtual machine.

Sphere and Anza core engineering are collaborating to enable the next-generation of cross-border payments based on Solana technology. This article outlines the architecture of how Sphere is reimagining the technical architecture of cross-border payments using Solana.

Details of the Agave Network Patch.

AccountsDB is Solana’s custom accounts database. This post contains a high-level overview of core concepts and then explains it's implementation details in context of Anza’s Agave implementation written in collaboration with the Sig Engineering team from Syndica.

A Release Candidate of the new Solana JavaScript SDK (@solana/web3.js) v2.0.0 is now available for evaluation, testing, and feedback.

With the release of Agave 2.0, Anza is rolling out a brand-new crate, designed specifically for projects building with SVM. This new library - solana-svm - gives developers the ability to drive the lower-level SVM components without the rest of the validator.

Starting with Agave v1.18, a new scheduler called the "Central Scheduler" will be included as an option which can be enabled by validators. The new scheduler adds an additional 7th thread to the scheduler called "The Scheduler Thread" which minimizes conflicts by selectively feeding transactions to the four worker threads.

A quick post written for the Solana Discord server to provide further details around the upcoming Solana Labs fork.
