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 🏗️🚢

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.

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 github.com/rustaceanrob/

* 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.

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.

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 🇧🇷.

You know what’s frustrating? When you’ve got the skills, the drive, and the ideas to make an impact, but the only thing stopping you is a border stamp. That’s the reality for so many brilliant Bitcoin developers across Africa and the Global South. They can write world‑class code, contribute to open‑source, and push the ecosystem forward, but collaborating in person with global peers or speaking on major stages? Too often, visa challenges make that impossible. We’ve decided that can’t be where the story ends. That's why we created the Pull Partnership; a way to place our grantees directly inside top Bitcoin teams around the world, where they can learn, share, and grow without barriers holding them back. The idea started when our grantee, @sadeeq_ismaela, joined @ChaincodeLabs in New York 🇺🇸 last year. He spent time working alongside leading Bitcoin developers, gaining hands-on experience and navigating the visa maze. That success made us think: what if we made this kind of opportunity a standard part of our grant ecosystem? Fast forward to this year. We’ve just piloted the Pull Partnership with @2140_dev in Amsterdam 🇳🇱. We’ve paired the Btrust‑funded developers with their team, covering salaries, relocation costs, and visa support, while 2140 provided mentorship, career development, and access to key Bitcoin industry events. We’d like to say a huge thank you to @josibake, @SomsenRuben and the @2140_dev team for making this partnership a reality. Learn more about the Pull Partnership here: blog.btrust.tech/introducing-th…
