# Become a Btrust Builder

Btrust Builders is our program to educate software developers from Africa about Bitcoin and Lightning development, and start them on their journey as open-source Bitcoin contributors.

The pathways are designed to build strong foundations in Bitcoin and progress toward meaningful open-source contribution, whether you’re just getting started or sharpening advanced skills.

You can learn at your own pace using our always-available materials, or [apply](https://btrust.homerun.co/btrust-builders-application/en) to join a live, guided cohort with small study groups, mentorship, and evaluation.

Pick a pathway. Learn deeply. Build readiness for open-source Bitcoin.

### How the Builders Journey Works

Btrust Builders operates as a progressive contributor pipeline:

* **Pathways (On-Ramps)**\
  Structured learning programs that build technical understanding, contribution habits, and readiness.
* **Open Source Fellowship (Acceleration)**\
  A contribution-driven program for top performers working on real Bitcoin open-source projects.
* **Outcomes**\
  Long-term contribution, grants, ecosystem roles, and alumni collaboration.

Pathways are the entry point. Progression is based on demonstrated readiness, not automatic advancement.

### Choose Your Learning Mode

<details>

<summary>Self-Paced Learning (Always Available)</summary>

Learn independently using Builders materials and the [Resource Hub](https://pathways.btrust.tech/resource-hub).

* No application required
* Learn on your own schedule
* Access readings, exercises, and discussion prompts
* Ideal for exploration, skill-building, or busy schedules

<a href="01/mastering-bitcoin/self-paced-learning" class="button primary">Start Self-Paced Learning</a>

</details>

<details>

<summary>Live Cohort (Limited &#x26; Selective)</summary>

A guided learning experience with structure, accountability, and mentorship.&#x20;

* Application-based, fixed start/end dates
* Weekly study groups and mandatory cohort sessions
* Assigned chaperone for guidance, mentoring, and grading
* Graduates listed publicly
* Required for Fellowship consideration

<a href="https://btrust.homerun.co/btrust-builders-application/en" class="button primary">Apply for a Live Cohort</a>

*Due to high application volume, not all learners will join live cohorts, and that’s intentional. The Pathways are built to support both independent and guided learning without loss of quality.*

### Frequently Asked Questions

<details>

<summary>How do the pathways work in 2026?</summary>

Btrust Builders Pathways are structured learning tracks designed to help developers build real capability in Bitcoin and open-source development.

In 2026:

* Most pathways are available year-round in self-paced mode
* Some pathways also run live, guided cohorts at specific times
* You can enter at different levels depending on your background
* Progress is measured through proof of work, not attendance

Each pathway clearly explains:

* Who it’s for
* What you’ll learn
* How to participate (self-paced or live)
* What completion looks like

You choose the pathway and learning mode that best fits your goals and availability.

</details>

<details>

<summary>What’s the difference between self-paced learning and live cohorts?</summary>

**Self-Paced Learning**

* Learn independently, on your own schedule
* No deadlines, live sessions, or evaluations
* Structured materials, prompts, and guidance provided
* Best for busy schedules, exploration, or refreshers

**Live Cohorts**

* Fixed schedule with weekly sessions
* Small study or homegroups with peer accountability
* Guided discussions, feedback, and evaluation
* Limited spots and selective admission
* Required for progression into certain advanced Builders programs

Both modes are designed to be high-quality. The difference is structure and accountability, not content quality.

</details>

<details>

<summary>Do I have to pay to join?</summary>

All pathways are **free to participate in**.

We remove financial barriers so learners can focus on:

* Showing up consistently
* Doing the work
* Building real skills and public proof

What we *do* require is commitment. Pathways are demanding by design, and spots in live cohorts are limited.

</details>

<details>

<summary>How do I choose the right pathway?</summary>

Start by being honest about where you are right now.

As a general guide:

* New to Bitcoin or want strong fundamentals?\
  → Start with *Mastering Bitcoin*
* Understand Bitcoin basics and want hands-on experience?\
  → *Learn Bitcoin from the Command Line*
* Comfortable with programming and ready for real code?\
  → *Rust for Bitcoiners* or *Language Clubs*
* Unsure where you fit?\
  → Start with a foundational pathway, then progress forward

Each pathway page clearly states:

* Prerequisites
* Level
* Expected commitment

When in doubt, start earlier rather than later. Foundations compound.

</details>

<details>

<summary>Can I join more than one pathway?</summary>

Yes — but not at the same time in most cases.

We strongly recommend focusing on one pathway at a time, especially for live cohorts.&#x20;

Why:

* Pathways require consistent weekly effort
* Splitting attention usually leads to shallow learning
* Builders prioritizes depth over speed
* Most pathway cohorts run in parallel.

You’re welcome to complete pathways sequentially as you progress.

</details>

<details>

<summary>How does the Open Source Fellowship work?</summary>

The Open Source Fellowship is a separate, advanced program.

* It is not open enrollment
* It is by invitation or application
* Selection is based on demonstrated proof of work, not credentials

Typically:

* Strong performance in live cohorts
* High-quality public work (code, research, contributions)
* Consistency, collaboration, and reliability over time

Completing a pathway does not guarantee fellowship placement, but it is often the first step toward it.

</details>

<details>

<summary>What if I am already well past all these pathways and fellowship?</summary>

You might be ready for the Btrust Grants. Grants are based on proof of work.

We currently offer:

* **Starter Grant** (full-time funding for six months)
* **Open-Source Cohort** (structured support while contributing long-time)

See [btrust.tech/grants](https://www.btrust.tech/grants) for details.

</details>

<details>

<summary>Do you have resources on open-source contribution?</summary>

Yes. Start with [Open Source Contribution Notes](https://pathways.btrust.tech/resource-hub/open-source-contribution-notes).

You can also browse the [Resource Hub](https://pathways.btrust.tech/resource-hub) for developer tools and reading.

</details>

<details>

<summary>Will I get a job with Btrust after completing one or more of the pathways?</summary>

Btrust does not hire developers directly. We support contributors through grants.

Pathways help you build proof of work. Proof of work helps you qualify for grants.

</details>
