Beyond the space itself, what excites us is what this unlocks for Bitcoin builders. A focused environment for open-source contribution, protocol-level thinking, and disciplined shipping. A place where developers can run nodes, test ideas, review code, and collaborate around Bitcoin-first principles. Stronger ecosystems are built by those who contribute upstream. We’re looking forward to deepening that culture. First Bitcoin Lab in Africa!!! #dadahub #build4africa

BIG ANNOUNCEMENT!!!🎉🥁 For a long time, Dada Hub has lived in strategy documents, late-night planning calls, and the collective imagination of a community that believes Africa deserves Bitcoin-native infrastructure built with intention. Today, we are proud to announce the space is secured!! The setup is underway. What we are building is not simply a venue, but an operational backbone for Bitcoin-native talent, product thinking, and ecosystem execution. As our programs have expanded and the depth of builders emerging from Bitcoin Dada & @DadaDevs has increased, it became clear that we needed infrastructure that supports serious work, not just community gathering. The Hub is designed as an applied Bitcoin lab — a controlled environment where capital, talent, and technical thinking can converge. Rather than merely hosting sessions, it enables sustained engagement, disciplined experimentation, and ecosystem-grade execution. It is about creating the physical layer that supports long-term market participation, not just short-term programming. This is an intentional step toward sustainability and stronger ecosystem integration. We are thinking long-term: about talent pipelines, about institutional collaboration, and about how to make KENYA an undeniable node within the global #Bitcoin network. More details about the official launch will be shared soon. For partners, builders, and aligned institutions who understand that infrastructure precedes impact, you already know what this means. We are building with permanence in mind! 1/2

When Satoshi Nakamoto created Bitcoin, they needed a language that could handle direct memory control, high performance, and low-level system access, all critical for a decentralized currency that relies on cryptography and peer-to-peer networking. C++ was the obvious choice because it offered speed, deterministic behavior, and mature libraries for complex data structures. Plus, Satoshi wanted a language that could prevent accidental bugs in money handling. Ever wondered why C++ was the choice? #DadaDevs #Bitcoin #BitcoinDevelopment

Last week, through the lens of @Chaitika_ the focus was on Scripting, key control, and transaction-level behavior. Script was approached through execution rather than abstraction, with emphasis on how outputs define spend conditions and how validation enforces them. P2PKH, P2SH, and P2WPKH were used as reference points, particularly in understanding SegWit’s role in transaction structure, weight, and malleability fixes. Spending conditions were extended into multisig, timelocks, and HTLCs. This covered m-of-n authorization, absolute and relative timelocks via nLockTime and nSequence, and hashlock constructions for conditional flows. On the security side, the discussion centered on key ownership. Authentication and authorization were separated at the wallet level, with cold storage treated as an operational necessity for minimizing key exposure. Threat models focused on realistic vectors, including malware, phishing, and physical compromise. At the transaction layer, signatures and fee rates were examined in relation to validation and mempool policy. Privacy was discussed in terms of UTXO linkability, CoinJoin usage, and the impact of address reuse on traceability. #BitcoinDevelopment #BitcoinSecurity #DadaDevs

Another week of class⚡ This time we’re deconstructing the shift from P2PKH to P2WPKH. What changed in the transaction structure, why SegWit introduced it, and what it means for fees and signatures. Swipe through for the breakdown. #DadaDevs #Segwit #BitcoinDevelopment

Over the weekend, the Dada Hub space hosted members of the Bitcoin Dada community for a practical session on peer-to-peer Bitcoin trading using @vexl. The focus was simple: hands-on learning, open discussion, and a chance for participants to explore how these tools work in practice. Dada Hub exists to support exactly this kind of engagement. It is a dedicated environment where communities working around Bitcoin, technology, and digital innovation can come together to learn, exchange ideas, and collaborate in a setting designed for focused work. As the hub continues to grow, we are looking to connect with organizations, collectives, and partners who are interested in using the space for workshops, learning sessions, and collaborative initiatives. If your community is exploring meaningful work in this space, we welcome the opportunity to collaborate. 📩 hello@dadahub.org #DadaHub #BitcoinDada #Vexl #BitcoinCommunity #Collaboration

This past weekend, we welcomed members of the Bitcoin Dada community to Dada Hub for a high-impact, hands-on workshop exploring peer-to-peer Bitcoin trading using @vexl. Although the Hub is still undergoing its final refinements, it is already serving its core purpose. Dada Hub was designed as a premium, purpose-built environment where our students and Bitcoiners gather to engage deeply with transformative technologies, collaborate meaningfully, and translate knowledge into practical capability. The workshop demonstrated exactly what that vision looks like in practice.

Taproot shipped in November 2021, combining three proposals that fundamentally reshaped how complex transactions are constructed, validated, and appear on-chain to an outside observer. Three of these options were central to that activation argument. Can you spot the imposter?

Nearly half of Africa’s STEM graduates are women. Yet their presence drops sharply in the technology workforce. Women occupy roughly a quarter of technical roles across the continent, and even fewer are in positions where engineering direction and product architecture are shaped. The issue has never been capability. The challenge has been access to the spaces where technical skills are refined, ideas are tested, and real systems are built. That is why Dada Devs exists. Within this community, women are committing to the technical side of emerging technologies. They study Bitcoin at the protocol level, strengthen their engineering foundations, and engage in research and development around the systems shaping the future of open digital infrastructure. With March recognized globally as a month to celebrate women, we are proud to spotlight some of the engineers (@junearsenic7, @KalukiTiiime and @NNakhero ) at Dada Devs. Developers building the technical depth required to contribute to Bitcoin and the broader frontier of decentralized and intelligent systems. The future of technology will be written by builders, and these women are part of that story. #IWD #DadaDevs #BitcoinDada #WomenInTech #BitcoinDevelopers

This past week, the Dada Devs fellows covered three lectures under the guidance of @ANaiyoma and the depth of what was covered speaks for itself. We covered: Bitcoin Core Development Environment: Configuring the core build, compiling from source and running a fully validating Bitcoin node on the network. Keys, Addresses and Wallets: Private and public key cryptography, address derivation, hot vs cold storage, custodial vs non-custodial wallets, HD wallet architecture, mnemonic seed phrases and the BIP32, BIP39 and BIP44 standards that define how modern wallets are structured. Transactions: The UTXO model, transaction structure from inputs to outputs, how digital signatures prove ownership without revealing private keys and a SegWit overview covering how it solved transaction malleability and expanded block capacity. The fellows are going deep, and we are only just getting started. #DadaDevs #BitcoinDevelopment

𝐂𝐨𝐧𝐜𝐞𝐩𝐭 𝐨𝐟 𝐭𝐡𝐞 𝐃𝐚𝐲: 𝐖𝐨𝐫𝐦𝐡𝐨𝐥𝐞 𝐀𝐭𝐭𝐚𝐜𝐤 In distributed networks, assumptions about topology matter. A wormhole attack occurs when an adversary tunnels packets between two distant parts of the network, making nodes appear closer than they actually are. The result is distorted routing and manipulated message propagation. Studying these attack models sharpens our thinking about network resilience. Security starts with understanding the adversary. ⚡ #Bitcoin #DadaDevs #BitcoinDev #BitcoinDevelopment

It’s time to get schooled 📚 Do you actually know what BIPs are or why they matter? Bitcoin does not just upgrade itself. Every change starts as a BIP, a Bitcoin Improvement Proposal. It is the blueprint for how the network evolves. From small tweaks to game changing upgrades, BIPs shape the future of Bitcoin. Swipe through and level up ⚡ #Bitcoin #Dadadevs

Last Wednesday, we took the fellows through Bitcoin 101, how it works and why it matters. Under the guidance of @wandiology, the fellows spent the evening building a solid foundation in Bitcoin from the ground up. We covered: 🔷 What Bitcoin is: A decentralized digital money ecosystem built on cryptography. 🔷 The Role of Cryptography: Digital signatures and how the double-spend problem was solved. 🔷 Bitcoin Wallets: How they work, hot vs cold storage, and keeping funds secure. 🔷 Public & Private Keys: How ownership works on the Bitcoin network. 🔷 Transactions: How value moves from one person to another. 🔷 Nodes: What keeps the network decentralized and running. 🔷 Mining & Proof of Work: How new bitcoin enters circulation and the chain stays secure. 🔷 The Lightning Network: Bitcoin’s Layer 2 for fast, low-cost payments. We are excited for all they have to learn and we are only just getting started! #Dadadevs #BitcoinDevelopment

AI is rapidly reshaping how we work, build, and think. From automation to agents, adoption is accelerating across industries, but the intersection of Bitcoin and AI is still largely underexplored. Where do these two forces converge? What opportunities are overlooked? And how can builders position themselves early? Join us for a Twitter Space on Bitcoin × AI, featuring @callebtc @MouxDesign @D_plus__plus, experienced builders exploring the intersection of both worlds. Hosted by @marcelorraine as we unpack practical integrations, emerging use cases, and the opportunities hiding in plain sight. Bring your perspective. Builders, operators, and the curious are all welcome. Set that reminder👇🏽 #AI x.com/i/spaces/1YxNr…
