In Their Own Words: Reflections from the Q1 2026 Self-Paced Tracks
In Q1 2026, Btrust Builders ran two learning pathways in parallel: Mastering Bitcoin and Learn Bitcoin from the Command Line. Each pathway had two tracks: a live cohort with weekly sessions, chaperones, structured assignments, and formal graduation requirements; and a self-paced track for developers who wanted to study the same material independently.
We recently celebrated the live cohort graduations. This post focuses on the other side of that same quarter: the self-paced learners.
The self-paced tracks were designed for developers balancing learning with work, school, exams, family, and other responsibilities. They received the same core materials as the live cohorts, along with learner guides, weekly prompts, Discord check-ins, moderator support, and open office hour sessions. What they did not have was the fixed structure of weekly attendance or live cohort grading.
Instead, completion was recognised through a written self-assessment: a published article or reflection documenting what the learner studied, where they struggled, what changed in their understanding, and what they plan to build next.
By the end of Q1, 13 developers submitted written reflections: 10 from Mastering Bitcoin and 3 from Learn Bitcoin from the Command Line. Together, these submissions represent the first self-paced completion pool for potential recognition, grant shortlisting, and deeper program engagement.
Below is what they wrote.
Mastering Bitcoin Track
The Mastering Bitcoin self-paced track gave learners the opportunity to study Mastering Bitcoin: Programming the Open Blockchain independently. The track focused on Bitcoin fundamentals: transactions, wallets, keys, mining, consensus, fees, scripts, Taproot, privacy, and the design choices that make bitcoin work.
For many learners, the pathway revealed a gap between being able to talk about Bitcoin and truly understanding it at the protocol level.
Hussein
Hussein came into the pathway confident. He had explained bitcoin to people and knew the talking points. However, the seven weeks of close reading revealed the gap between being able to talk about something and actually understanding it.
The fees chapter was where it got embarrassing. "I thought about how many times I had explained fees as a small charge. That framing completely hides the truth. It's not a charge. It's a bid. Every transaction is competing with thousands of others for space in the next block. I rewrote my mental model of fees from scratch that week."
Mining hit harder. "I used to explain mining like this: miners solve a puzzle and new bitcoin gets created. Bitcoin isn't issued because miners solve puzzles. Miners solve puzzles because that's the only known way to get thousands of strangers, with no reason to trust each other, to agree on one shared version of history. The new bitcoin is just an incentive. The real product is consensus."
Hussein is now building Bitcoin Lasgidi, a Bitcoin developer community at his campus in Lagos.

Ebube Miracle Ukpai
Ebube had developer experience and enough bitcoin familiarity to feel comfortable in most conversations. He knew about Taproot, had heard of Lightning, understood HD wallets at a surface level. What he was missing was the connective tissue behind the design decisions, the tradeoffs that shaped the protocol, the mental models that make everything else make sense.
The UTXO model was the concept that changed the most for him. In his words, "That reframe changes everything. It changes how you think about privacy; address reuse links your UTXOs together publicly. It changes how you think about fees , they're the implied difference between inputs and outputs, never explicitly stated. It changes how you think about wallet design, transaction construction, and even the economics of small payments."
The hardest part was not cryptography, as he expected, but Schnorr multisig and the key cancellation attack. Working through it required sitting with the discomfort of not immediately understanding something. He is now planning to build a Bitcoin wallet from scratch and contribute to Bitcoin Core, rust-bitcoin, and BDK.

Kamogelo Aphane
Kamogelo describes completing the pathway as gaining a new set of eyes. What began as curiosity about digital gold became, over eight weeks, a rigorous study of distributed systems, cryptography, and game theory.
What surprised her most were the incentives. "The difficulty adjustment algorithm is perhaps the most underrated piece of engineering in the 21st century, the heartbeat of the network, ensuring that no matter how much hash power enters or leaves, the block interval remains constant."
By the end, she had three projects mapped out: A non-custodial Lightning wallet that prioritizes user sovereignty, an exploration of Onion Messages for metadata-free peer-to-peer coordination, and a DLC-based weather insurance product for small-scale farmers. She wants to build a decentralised, oracle-based weather insurance tool, and a trustless safety net without a centralised middleman."

Timothy Chimbiv
Timothy came in as a Stacks developer writing smart contracts in Clarity, and the pathway rebuilt the foundation he had been building on. In his words, "A bitcoin wallet doesn't hold bitcoin. It holds your keys. The bitcoin lives on the blockchain, your keys just prove you can spend it. That reframing changed how I think about custody and security entirely." This was an insight that landed the most for him.
He is now going deeper into Lightning and building on Stacks with more intentionality about staying within bitcoin's decentralized security model.

Collins Mwanga
Collins came in thinking of bitcoin as magic internet money. Bitcoin Script was his hardest chapter. In his words, "Reading scripts felt like learning a tiny programming language. I had to go through examples multiple times before understanding how transaction conditions are verified. What helped most was slowing down, drawing diagrams, and experimenting with small code snippets."
He plans to focus on Bitcoin infrastructure, privacy tools, and making technical bitcoin education more accessible across Africa.

Goodness Bakinde
Goodness worked through all 14 chapters and describes Taproot as his standout: "Schnorr's linearity enables powerful features like scriptless multisignatures, making complex multi-party setups indistinguishable from simple single-signature transactions on-chain. This leap in privacy and efficiency was eye-opening."
He is now moved into the Bitcoin CLI pathway.

Jonjay
Jonjay came to the pathway with no technical background in Bitcoin.
"I used to think bitcoin was just 'that coin' for rich people on X. I never really understood what was happening underneath." By the end, his frame had shifted entirely: "It is economics. It is game theory. It is freedom. It is coordination at a global scale without trust."
He made his first open-source contribution, to BTCPay Server, during the pathway.

Khalid Yusuf
Khalid went in expecting a technical overview and found, he writes, "a blend of computer science, economics, and philosophy that challenged my assumptions about money and trust in digital systems."
His view of bitcoin shifted from investment to infrastructure. He is now experimenting with testnet transactions and plans to go deeper into Lightning.

Clerence
Clerence's starting point was familiar: he thought a wallet stores coins. Learning about hierarchical deterministic wallets and derivation paths dismantled that entirely.
"Understanding HD wallets and derivation paths changed my mental model completely. A single seed phrase can generate many addresses, all controlled by the same cryptographic root. This forced me to move away from thinking in terms of accounts and toward thinking in terms of key ownership."
The Byzantine Generals Problem was the concept that gave him the deepest appreciation for bitcoin's design. Understanding why reaching agreement in a decentralised system with untrusting participants is so hard, and how proof-of-work solves it, made the protocol feel less like a technology and more like a carefully reasoned argument.
He is now exploring node infrastructure, scalability constraints, and building systems that can operate in resource-limited environments.

Abdulmajid Yunus
Abdulmajid came in with a goal to understand bitcoin well enough to explain it in non-technical terms. What he ended up doing was considerably more.
He ran a node on his machine, performed a testnet transaction in Sparrow Wallet, created SegWit, Taproot, and multisig wallets, and connected Sparrow to his local node. When CompactSize encoding in transaction hex stumped him, he built a tx-decoder, an educational tool for parsing the binary structure of Bitcoin transactions, to work through it properly.
He has already made contributions to rust-bitcoin and rust-payjoin, and is actively looking to go deeper into both projects. "When I come back to this in a year, I should be able to see my name, in multiple Bitcoin open-source projects."

Learn Bitcoin from the Command Line Track
The Learn Bitcoin from the Command Line self-paced track focused on practical, hands-on interaction with Bitcoin Core. Learners worked through command-line usage, node configuration, raw transactions, scripts, multisig, PSBTs, RBF, CPFP, and other low-level Bitcoin operations.
While Mastering Bitcoin helped learners strengthen their conceptual foundation, the CLI pathway pushed them to interact directly with the protocol.
Muhammad Ademola
Muhammad's submission walks through configuring Bitcoin Core, building raw transactions, testing RBF and CPFP hands-on, and working through multisig and PSBT. The most significant work happened alongside the curriculum.
He investigated a security vulnerability in BDK Wallet, traced it across multiple dependency layers, and found the real blocker upstream in two libraries without stable releases. The lead maintainer reviewed his issue and added it to the official Wallet 4.0.0 milestone. He contributed PRs to Cove and Floresta in parallel and is monitoring upstream libraries for the next fix.
His contributions this quarter span five PRs and issues across BDK Wallet, Cove, and Floresta.

Usman Umar Garba
Usman came in with a longer Bitcoin arc behind him. In 2025, his team built BitTicket, a decentralised ticketing platform using Bitcoin transactions, through the African FreeRouting Lightning Bootcamp. The CLI pathway shifted how he engaged with the protocol at its base layer. "Before this pathway, I mostly interacted with bitcoin through wallets and high-level explanations. Using bitcoin-cli forced me to work directly with the protocol itself."
His BOSS Challenge project, a Rust-based Lightning UTXO and Anchor Manager for Lightning node operators, was featured on the BOSS Challenge portfolio. He is now building SatsFor, a Lightning-based mobile tipping application in Flutter and Rust.
In his words, "A creator in Lagos should be able to receive sats instantly from someone anywhere in the world without depending on traditional payment systems, delays, or high fees."

Ogunseye Oluwajuwon Michael
Ogunseye completed the CLI pathway for the second time, this time alongside AI engineering final exams. The self-paced format made that possible.
He built a multisig wallet in Python, worked through PSBT and RPC commands, and describes where he landed: "I still consider myself early in the journey, but I now feel much closer to the direction I want to grow in."

What the Self-Paced Reflections Show
Across both pathways, the reflections reveal a few clear patterns.
First, the self-paced format did not reduce the depth of learning. Learners were not simply consuming material passively. They were revising mental models, building tools, running nodes, creating wallets, testing transactions, contributing to open-source projects, and forming clearer technical goals.
Second, written reflection proved to be a useful completion signal. It gave learners a way to demonstrate understanding in their own words while also documenting their growth publicly. For some, the article itself became a bridge into the next phase of their Bitcoin development journey.
Third, self-paced learning widened access. Several learners were studying around exams, jobs, or other responsibilities. The ability to move at their own pace made it possible for them to continue without being excluded by the structure of a live cohort.
Finally, the reflections point toward the next stage of the self-paced framework. Written self-assessments are a strong first signal, but the program is now working toward adding more outcome-based indicators, including pull requests, code contributions, technical projects, and open-source participation.
If you are working through the Btrust Builders pathways, or considering starting, these are the people ahead of you on that path. The material is the same and the pathway is open. If you are ready to begin, you can apply to the Btrust Builders program here.
