Gridless

Today we’re announcing a developer release of the Jua Kali Miner - an open source project that allows farmers and small industries to make use of their excess solar energy to mine Bitcoin. With a live demo at #abc25

@akaKush0 No. It lowered the temperature a bit.

@GridlessCompute Looks cool! Does the low ceiling affect air intake?

New filters for cooling. Always fighting the twin dragons of heat and dust!

Before bitcoin++ Nairobi 🇰🇪 kicked off, we brought together Btrust developer grantees and team members for a retreat at @NodeNBO. With many of our grantees already in Nairobi for bitcoin++, it felt like the perfect opportunity to spend a day together, connecting, sharing progress, aligning on priorities, and strengthening the relationships that make our ecosystem what it is. For many of the grantees and some of our newer team members, this was the first time meeting in person after months (and in some cases years) of collaborating online.

Cool BTC surfboard to add to our knickknack shelf from our friends at @BitcoinEkasi - thanks!

@ryankuester Karibu anytime. :)

Thanks for hosting me! It was instructive and perspiring—I mean inspiring—to see Gridless in action.

Last week we had the pleasure of supporting @btcplusplus Nairobi 🇰🇪, the first bitcoin++ conference in Africa and the first-ever open source edition. Over three incredible days, we saw developers, researchers, educators, and builders come together to explore Bitcoin, Lightning, privacy, mining, open-source development, developer tooling, financial infrastructure, and the future of building on Bitcoin. It was inspiring to see so many ideas turn into working projects tackling real-world challenges. We're especially proud of the strong representation from our community, with members speaking across the conference and teams building projects that earned recognition across multiple hackathon categories. A huge thank you to @niftynei and the entire bitcoin++ team for bringing this milestone event to Africa, as well as the speakers, mentors, judges, volunteers, sponsors, and every attendee who made it such a success. We're excited to see the projects, collaborations, and conversations that started here continue long after the conference. See you next year! 🚀

In 2026, @tando_me makes it possible to live on Bitcoin Kenya. They are now combining M-Pesa and Bitcoin's Lightning Addresses to unlock that for 40 million Kenyans 🔥 Read more in my latest for @ForbesCrypto forbes.com/sites/digital-…

People ask why we do this. Here's the answer. A documentary on Bitcoin education in Africa, made with @Trezor.

He also joined us for a visit to our 1.5MW biomass site. Braving Kenya’s roads, and seeing how we battle dust and heat.

We had @ryankuester in Kenya for @btcplusplus last week. Here is his @256FOUNDATION podcast on his experiences and seeing how open source bitcoin mining is such a big deal for us in Africa. podcasts.apple.com/us/podcast/pod…

@whiteafrican speaking on decentralized mining powered by Juakali @GridlessCompute @GAMA_alliance @btcnairobi_conf

Swing by our space and listen to Erik and the team talk at 2pm today about our Jua Kali miner at @btcnairobi_conf Jua Kali is an open source project turning solar 12v mining on with old hashboards.

We’re kicking off with @rkirubi setting the stage for why bitcoin and why Nairobi. @btcnairobi_conf

At @btcnairobi_conf at ASK Dome today, looking forward to hanging out with everyone, but especially @rkirubi and @OKIN_17 again!

Taking some @btcplusplus to see our biomass site in Kenya.

Next up is the team from @protomining talking about their mining rig and the open source fleet management software. @BitDevsNBO

Day 3 of @btcplusplus open source edition kicks off with a talk from Sy⚡️(@dzeg5) about open source mining and what they’ve built on the @StratumV2 team

The final hackathon presentations at @btcplusplus are officially complete. Selected finalists presented open-source projects, demonstrating creativity, technical skill, and a commitment to advancing the Bitcoin open-source ecosystem. While the judges deliberate, here are some highlights from some participants 🥳

A 60x gap. That's the reality @_bradcuddy_ used to explain why public Bitcoin miners are pivoting to AI. An AI data center earns ~$6,000 per megawatt hour on its compute. A Bitcoin miner earns about $100. 🧵/

@rsadiqra @abcptza @Machankura8333 @btcplusplus @dzeg5 Thanks! Simon’s great, love his Stratum V2 work too.

@abcptza @Machankura8333 @GridlessCompute @btcplusplus @dzeg5 killing it 🫡

Hey @GridlessCompute, I spy a locally-made BitShoka at @btcplusplus Open Source Edition, I’d like to know more.
