Our team will be be attending and speaking at this year’s edition of @bitcoinconfams 🇳🇱. Bitcoin Amsterdam brings together developers, entrepreneurs, researchers, investors, and community builders from across the global bitcoin ecosystem to exchange ideas, explore emerging developments, and discuss the future of bitcoin. Tomorrow, @ihate1999 and @sadeeq_ismaela will take the stage alongside Rob Netzke for a discussion on getting started in Bitcoin open-source development. Later in the day, @ihate1999 will take the Treasury Stage to explore the priorities, principles, and trade-offs shaping bitcoin’s future, from individual sovereignty to mainstream adoption, and whether the community needs a shared vision or room for disagreement. We’re looking forward to meeting fellow builders and members of the wider Bitcoin community, exchanging ideas, and exploring opportunities to build together. See you there! – at Amsterdam, The Netherlands

We’re on at the proof of work stage at @bitcoinconfams.📍 @ihate1999, @sadeeq_ismaela, and Rob Netzke are discussing how newcomers can find their way into Bitcoin open-source development, including the different skills, communities, mentorship opportunities, and practical pathways that can help turn curiosity into meaningful contributions.

On 6 November I’ll be at Bitcoin Amsterdam on the Proof of Work Stage moderating: Who Controls the Mining Stack? I’ll be joined by: - Duncan Coombe - The Solo Mining Co - Abubakar Sadiq Ismail - 2140.dev - BitMaker - Bitronics We’ll be looking at where real control sits in Bitcoin mining today. The discussion will cover how open source hardware and tools can shift that balance, the practical difference home miners can make against large industrial operations and what would need to change for independent mining to become a counter to centralisation. bitcoin.amsterdam

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.
Nominations are open for the 2026 Bitcoin Research Prize! Submit papers that made an impact on Bitcoin or Lightning published after 2022: forms.gle/DzN1gt7XbgEcMFxw6 Have you (co)authored any papers that fit this criteria? Submissions are anonymous 😉

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 🇧🇷. – at Sao Paulo, Brazil
