This course is designed for Product Managers who are serious about building Bitcoin-powered products that protect users, survive pressure, grow responsibly, and outlast hype cycles. Across 21 practical, deeply human-centered modules, you will learn not just how Bitcoin works, but how to design, prioritize, and ship Bitcoin experiences that: * Serve merchants, migrants, activists, and everyday savers, * Protect autonomy, liquidity, privacy, and dignity, * Sustain business models without betraying user trust, * Build resilient, ethical companies that will stand for decades. You will leave this journey not simply as a PM who "understands Bitcoin", but as a builder of infrastructures that defend freedom, stability, and future generations. This is not a crypto product management course. This is Bitcoin product discipline. And it is built for those who intend to lead. ## Full table of contents | Module | Title | Description | | - | - | - | | 1 | What Bitcoin Really Is | Understand Bitcoin as a system of money, freedom, and survival not just digital currency and why its principles must shape product decisions. | | 2 | Private Keys, Public Keys, and Bitcoin Addresses | Master how Bitcoin keys and addresses work, how ownership is proven, and how your product must secure them correctly. | | 3 | Understanding UTXOs | Learn why Bitcoin is not account-based, how UTXOs represent real spendable Bitcoin, and how they affect product design and fees. | | 4 | Anatomy of a Bitcoin Transaction | Break down the structure of Bitcoin transactions: inputs, outputs, signatures, scripts and design with real Bitcoin mechanics in mind. | | 5 | How Bitcoin Blocks and Confirmations Work | Understand Bitcoin block production, confirmation logic, and network consensus and how to reflect this transparently in UX. | | 6 | What a Bitcoin Wallet Actually Does | Clarify the real role of wallets from key management to transaction construction to user safety beyond just showing balances. | | 7 | Security Model of Bitcoin Wallets | Study real-world Bitcoin wallet threats from device loss to theft, and how to design security flows that protect users under pressure. | | 8 | Wallet Product Architecture Mapping | Map out custodial and non-custodial wallet architectures, infrastructure needs, risk points, and scaling challenges. | | 9 | Designing a Bitcoin Wallet for Real Users | Translate Bitcoin’s complexity into intuitive, human-first UX: for first-time users, refugees, merchants, and everyday savers. | | 10 | Designing Bitcoin Support for Existing Custodial Wallets | How to integrate Bitcoin into multi-asset custodial wallets practically, respecting Bitcoin’s special characteristics without overwhelming users. | | 11 | Bitcoin Address Types, Multi-Address Watching, Batching, and Webhooks | Master the operational basics of Bitcoin address formats, address monitoring, transaction batching, and webhook-driven systems. | | 12 | Designing Bitcoin Payment Products for Merchants | Blueprint for creating Bitcoin payment acceptance products: onboarding merchants simply, safely, and with strong incentives. | | 13 | Bitcoin Liquidity and Treasury Management for Wallets | Learn how to manage Bitcoin inflows, outflows, treasury security, and liquidity risks at platform and operational scale. | | 14 | Practical Bitcoin Product and UX Guidelines for Designers and Product Managers | Real-world design and product guidelines for building Bitcoin apps, services, and integrations users can trust and survive on. | | 15 | Bitcoin Security Operations (SecOps) for Companies | How to run Bitcoin security systems properly: treasury protection, multi-sig cold storage, hot wallet limits, incident response. | | 16 | Bitcoin Product Revenue Models: Building Sustainable Businesses | How serious Bitcoin products generate revenue honestly spreads, fees, premium services without betraying user trust. | | 17 | Key Performance Indicators (KPIs) for Bitcoin Products | How to define, track, and optimize Bitcoin-specific metrics like transaction trust, liquidity efficiency, retention, and growth health. | | 18 | Marketing Bitcoin Products | How to market Bitcoin products based on real problem-solving, survival use cases, storytelling, and circular economy activation. | | 19 | Building Bitcoin Products for Activists, Refugees, and Displaced Persons | How to design Bitcoin products for survival: fear, flight, censorship, hunger designing dignity into every pixel and flow. | | 20 | How Companies Can Incorporate Bitcoin Responsibly and Sustainably | A guide for any fintech, payment platform, or financial app adding Bitcoin wisely balancing user freedom, revenue, and trust. | | 21 | Mastering Bitcoin Product Building: Final Reflections and Action Tasks | Final practical exercises, checklists, and mastery reflections to turn knowledge into durable Bitcoin product discipline for life. | This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
