Tinydancer 🤏💃

Excited to share that we’ve launched our own Solana validator on mainnet!(8vk6QpG93JSaQCSgnycBsv5qmfQBk4qC9FjNA35E5JhU) - 0% commission - 0% MEV commission - Proceeds fund OSS contributions by @anoushk77 and @harsh_patel We’ve been quiet for a while. Here’s why and what we were up to...

a sneak & peep on how my jito shredstream xdp monitor looks like atm, vibe coded in bash. this screenshot was captured while the proxy was live and actively forwarding traffic, with actual counters. its displaying shreds received from the jito block engine in new york & forwards to a sink, bypassing the entire kernel networking stack. - single queue rx and tx - skb & drv mode the goal is to: - benchmark latency, cpu utilization of XDP based packet processing pipeline. - demonstrate a full xdp based shred forwarding pipeline that is not only reliable for more traffic but also handles packet bursts gracefully.

xdpdump is a very handy tool for diagnostics. below is my jito-shredstream fork redirecting shreds from the block engine in a fully kernel bypass pipeline. h/t @seminuked

i automated my nic monitoring for XDP with a skill that i plug into codex/claude. not all NICs/drivers are the same but this covers most of the general settings & metrics. it monitors: - bpf program attachment - NIC queue IRQs to CPU core affinity - free CPU cores - kernel tracing - fdir rule application - perf recording and report

Just got casually mentioned by @alessandrod today on his talk on agave performance and networking at Breakpoint. This is why I wake up and Solana. full talk: x.com/solana_devs/st…

We all know how painful it is to get locked out of ssh when experimenting with XDP. This one is a helpful primer for the people starting out with XDP based networking👇

Announcing Solana Network State: Road to Breakpoint – @ns on 20th november. – invite only. 80 builders. – real ICM insights reach out for collabs (sponsor/speaker) ––– more details soon. by @meteora_my @ionet @met_engine @SuperteamMY @sendarcadefun @tinydancerio

We're proud to be running the first release of FD-Paladin! Connected to both Jito and Bloxroute for the highest tips!

FD-Paladin is live on Mainnet! You can now connect multiple block engines (Jito + bloXroute) to @jump_firedancer @tinydancerio and Paladin-Firedancer are the first validators on Mainnet already producing blocks with txns from both block engines! Link to release below

We stand on the shoulders of giants! Thanks for your support!

Detailed setup guide, challenges faced and implementation details coming soon! Stay tuned.

💥 The AF_XDP receive path in Agave has been ACHIEVED, both zero-copy and copy modes SUCCESSFULLY TESTED end-to-end! 💥 A first step toward ultra-low-latency packet reception on @solana h/t @alessandrod for all the help 🤝 Zero-copy mode in IKVM console, more details 🧵:

🚨 Just wrote my own XDP redirect program in Rust (Aya). 🚨 Packets → NIC → AF_XDP → userland rings. ft. kernel trace logs Works in both copy and zerocopy modes.

incredible research, OSS projects and accelerating @solana dev infra with @tinydancerio ft. @harsh_patel

Tinydancer validator will vote in favour of the alpenglow proposal. We are committed to supporting upgrades that improve performance and sustainability of the network. Alpenglow brings IBRL to reality and we’re in for it.

Introducing an open source pinocchio-powered, modified asset-agnostic Solana orderbook. - integrate with any program - create/cancel orders, order feedback via OrderSummary - stream matches via an event queue, - custom callback data. This orderbook was first introduced by @bonfida in Breakpoint 2021 cc. @0x_febo @jacobvcreech

Mainnet -> mb.tinydancer.io Testnet -> testnet.tinydancer.io

Thanks to @CherryServers @Dovydavicius for providing us with a new machine for mainnet and testnet! We're now running the incredibly powerful 9375F in Amsterdam. Our Firedancer dashboards are live too, check them out below!

@benhawkins Thanks Ben!🙏

More of this 🙏
