Spotted at @2140_dev 👀

These socks are proven to make you a 10x developer

[Sergi Delgado ⚡ @sr_gi]

This is your reminder that the Bitcoin Research Prize nominations are still open.

TL;DR peer-reviewed research papers published in a recognized conference or journal after Jan 1st 2022. Nominations are anonymous. Self nominations are fine.

Did you know you can build a stick visualization of your mempool clusters and fee estimation using the getmempooldiagram RPC?

Did you know that if you also include PR #34075 you can see how accurate the fee estimation for previous blocks was?

Sadiq knew, be like Sadiq 🏗️🚢

- Visualize fee rate estimates for some confirmation target
- Benchmark accuracy against confirmed blocks
- Cluster Mempool feerate diagram

Next up: benchmarking against other estimators?

@boyacaxa Different protocol, not our great Rob.

[2140.dev @2140_dev]

Our Rob is not Rob the great*, but he is a great Rob, a devoted Rob. He's a dont-have-a-twitter-account Rob, a focused Rob. A speed-up-your-ibd Rob, a true committed Rob. He's been approved by the council of Robs**, a top notch Rob.

[Spiral @spiral_xyz]

We’re funding a guy named Rob via @2140_dev that they’ve assured us is a top notch Rob. He’ll be improving Core by speeding up initial block downloads using SwiftSync, continuing Kyoto work, adding integrations with LDK Node, Bull Bitcoin, Cove, and more

https://t.co/SfJgSleVx3

[2140.dev @2140_dev]

* The previous tweet may contain historically inaccurate information, but our Rob is great nonetheless.

** If you don't agree with the council's decision, you can take it with @Rob1Ham and @robertwarren.

[Vinteum @Vinteum_org]

Last week we hosted the 2nd @casavinteum Retreat, this time bringing together the full Floresta team, the Utreexo crew (@Erik17192799, @kcalvinalvinn, @tdryja) and @SomsenRuben representing SwiftSync and PoW fraud proofs to align on the roadmap for Floresta, utreexod and more. They also dove into spacechains, Kernel and a bunch of other ideas.

The meeting led to several exciting outcomes, from faster Utreexo bridges to plans for integrating SwiftSync into Floresta for even faster IBD. Huge thanks to @HRF for supporting this retreat. Davidson will share a full summary on Delving Bitcoin soon.

[Btrust @btrustteam]

Just wrapped up @satsconf_ 2025, and it was such an amazing experience!

On Day 2, @StephTitcombe got to speak on decentralizing Bitcoin development, where she highlighted the work we're doing in the Global South.

We're really happy to have been part of São Paulo Bitcoin Week.

Big shoutout to @lucasdcf, @brrrunog, and the entire @Vinteum_org and @satsconf_ team for putting together such an incredible week.

Looking forward to more of these. See you soon, Brazil 🇧🇷.
