Interested in FOSS and Bitcoin development ? Here is a great tool you can leverage to contribute to Bitcoin and one of the best application in the ecosystem 💚

Most bitcoin users never think about fee sniping; a scenario where a miner tries to re‑mine a recently mined block to capture the transaction fees inside it. To reduce the incentive for this, many wallets set a locktime, which helps ensure transactions are only valid for the next block. But this protective behavior has an unintended side effect: it can create patterns that make some transactions easier to identify on the blockchain. In our latest blog, @_abiodunAwoyemi dives into BIP326, a proposal that improves privacy for Taproot wallets without requiring any change to the Bitcoin protocol. The idea is simple: instead of always using nLockTime for anti‑fee‑sniping protection, wallets can sometimes use nSequence instead. Many off‑chain protocols like the Lightning Network⚡ already use nSequence for timelocks. If regular wallets also start using it, transactions that settle from off‑chain systems will blend in with everyday on‑chain activity. That makes it much harder for blockchain analysts to distinguish between the two. The result is a larger anonymity set, better privacy, and stronger fungibility for Bitcoin users. Abiodun walks through the mechanics behind locktimes, Taproot and MAST, why HTLC‑based systems leak information, and how BIP326 helps close that privacy gap, all the way down to a practical Rust implementation. If you’re curious about how a small wallet behavior change can strengthen privacy across the Bitcoin ecosystem, this is a great deep dive.

F1 2026 season so far

I love meeting people who are clearly enjoying their time on earth

"An experience that made me wake the fuck up was travelling with a Black person"

Lewis Hamilton breaking the record for most F1 career podiums (203) previously held by Lewis Hamilton (202)

these 3 were fighting for the championship last season

Btw Lewis will be the only F1 world champion to finish today’s race 😭

Bitcoin runs because of people. Developers who review code, fix bugs, debate tradeoffs, and quietly maintain the software behind a global monetary network. Btrust was created to help decentralize Bitcoin development across the Global Majority. One way we do this is by funding and supporting African developers contributing to Bitcoin open‑source projects. In 2025, we focused on building the systems to make this work better. We experimented, improved our processes, and strengthened the pipeline that supports developers contributing to Bitcoin. And our grantees delivered. They contributed to 15 Bitcoin open‑source projects, including @bitcoincoreorg, @lightningdevkit, @bitcoindevkit, @BtcpayServer, @lightningpolar, @bluewalletio, @VLSProject, Rust‑Bitcoin, and more. Together they produced 431 commits, 222 merged pull requests, and 475 code reviews, helping improve tools used across the Bitcoin ecosystem. This blog, co-authored by @kelvinator05, breaks down the projects they worked on, the technical contributions they made, and the impact across the Bitcoin stack.

Lovely to see one of our alumni doing amazing work and receiving funding in this round. 🫡🧡 We’re also excited to see more Africans getting recognized and funded by international organizations supporting Bitcoin open-source development. The talent is here, and it’s great to see it being supported.

@waithiraah @osumo_brad @thebigfishke @tando_me

@Murugi___ @osumo_brad @thebigfishke @tando_me I knew this one would speak to you. We might have to make a trip back there soon😉

Day 1 of proving you can pay for/buy things in Kenya using only Bitcoin! Today I bought lunch at @osumo_brad @thebigfishke Bitcoin for me. Kenyan shillings for them. Zero transaction fees too🔥 @tando_me

@Ihatebitcoin1 Awww, thank you for the feature Hussein 🥹🧡

Our guest for today, na @ihate1999, na him be di No. 1 Most Impactful African Bitcoiner for 2025. Na him also be CEO of @btrustteam wey also win most impactful project of the year. Watch this video make you hear im take on Bitcoin! 0:01 - We go like make you introduce yourself to our people wet dey watch 0:21 - Wetin be the experience so far for Mauritius 1:05 - Wetin be the message you get for people wey feel say Bitcoin na scam? 1:40 - Wetin you go tell developer wey get double mind about the ecosystem 1:55 - Wetin be the last message wey you get for us and wetin we need to expect from Btrust #bitcoin #africanbitcoiners #ABCZ

A both funny and educational meme. Let me explain: In the first panel, Joey is excited because the hotel’s “free Wi-Fi” is extremely fast. Anyone who has stayed in hotels knows their Wi-Fi is usually slow, overloaded, and frustrating. So when a connection suddenly feels blazing fast, it feels like you got lucky. In the second panel, Joey checks his device and notices his IP address starts with 172.16.42.x. His expression instantly changes to shock — because that number means something very specific in cybersecurity. That IP range is the well-known default network configuration used by a device called a WiFi Pineapple. A WiFi Pineapple is a portable penetration-testing tool that attackers can use to create rogue Wi-Fi access points. It can imitate legitimate networks … like a hotel’s Wi-Fi and trick nearby devices into connecting to it instead of the real network. Once your device connects, the attacker effectively becomes the network in the middle, allowing them to observe or manipulate traffic passing through it. This is a classic Man in the Middle (MitM) attack. The reason the connection feels “fast” is simple: you’re probably one of the few people connected to it, and the attacker is letting your traffic pass through so they can monitor it. So if you ever connect to public Wi-Fi and notice an IP address like 172.16.42.x, there’s a good chance you’re not actually on the hotel’s network…. you might be connected to a rogue hotspot controlled by someone else.
