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.

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.
