Solana has always forked Rust/LLVM to maintain its BPF target instead of giving back to OSS. Today, that all changes. Behold, a pinocchio escrow built with nightly Rust for upstream BPF with a custom sbpf-linker. Zero protocol changes. It is now safe to turn off your compiler. 👇

The last few days there were a ton of discussions on the VM toolchain Currently there's a few SIMDs out for the VM: - SIMD 117: ABI V2 - SIMD 167: LoaderV4 - SIMD 178: sBPF Static Syscalls - SIMD 179: Stricter sBPF verification constraints and more Where are we going?

Related to saving CUs, always use the latest platform-tools version. You don't need to update your Solana CLI, just add "--tools-version <version>" to cargo build-sbf. https://t.co/d8YAHERtAS
In another win for crate enjoyers, it turns out that using a bpf program as a library (instead of making a separate library crate) breaks LTO and wastes CUs

There is a new framework for writing programs – recommend checking it out.
The team just release star_frame to the world, 2 years in the making. https://t.co/Dp1saTmf4w

1/ Today we're launching comprehensive new documentation and API reference for the Solana Javascript SDK at https://t.co/kZm34pjGvy. This completes our transition to Kit, a reimagined way to build Solana applications and interact with on-chain programs 🧵

if you're a solana program dev, learn what no_std rust is today. you will thank me tomorrow

We've concluded our audit of P-Token, Solana's new token program build with Pinocchio. It promises impressive savings in Compute Unit (CU) usage. But what exactly does this mean in practice? We've investigated 👇️

If you ever worked with programs, you'll know that the worst thing to do is creating SDKs. NOT ANYMORE! @lorisleiva built Codama and accidentally made SDK development... fun?!? Learn how to use it in our new course ⬇️

how you like that mfkers (1 cu more on trivial case, many less on others) put some respek on my name
thought of a -1 CU on my walk back from gym 👍

Programs have a "cheaper" way to access more memory if they choose to do so. https://t.co/TGN7TrWsZJ

And the work to integrate pinocchio and the SDK types is underway. This will make it easier to write code that support both. https://t.co/dpYQ3Mr4c6

Problem Pinocchio re-implements many types from Solana SDK to avoid non-essential dependencies. Since now the SDK has been divided into separate crates and they are much leaner in terms of external...
