Just completed a Cognios Sprint at Solana Summit.

3 minutes to learn what Cognios is.
Now I’m in the running for a Solana Seeker.

Not a bad trade.

Ondřej Chaloupka (@_chalda), backend engineer at Marinade (@MarinadeFinance), is joining us at Solana Summit Serbia.

Marinade is the home for staking on Solana, and Ondřej builds the infrastructure behind it: liquid staking, native staking with its validator auction, and instant unstake all run on systems he helps engineer.

My machine kept freezing when I used async-profile.

This is the deepest I've ever gone: debugging a Linux kernel deadlock, performing live surgery on a frozen CPU with GDB, and pulling off a questionable resurrection.

📝 I have a write-up about working with @solana @anchorlang programs from different versions
and how to handle IDL incompatibilities for Rust and Typescript clients.

See the article here: https://t.co/gaNZCnYNYt

[Ondřej Chaloupka @_chalda]

I just found that the anchor-gen @anchorlang Rust library for IDL handling and managing compatibility with older Anchor versions was updated a few months ago to support the latest Anchor version. Nice.

[Ondřej Chaloupka @_chalda]

🚀 Thrilled to be speaking tomorrow at @AthensDAOx! I will be sharing insights on our journey with @MarinadeFinance in #Solana DAO management with @realmsdaos

[repe @repetny]

1/ In Q4 2024, @solana validators have captured $161M in transaction fees, making up 64% of their total revenue! 🚀

With no in-protocol way to share these fees, stakers miss out on this fastest-growing reward stream. So, how can they claim their share? Let’s dive in. 👇

[repe @repetny]

@mert @SolanaFloor @MarinadeFinance wrong, let's count together: 7.52% (inflation) + 3.25% (jito tips) + 1.58% (block rewards) = 12.35% APY total staking yield

block rewards (1.58% APY) go 100% to validators, while Marinade's auction lets validators share these back to stakers

that's where the yield comes from
