Trustless by Design
Gift Yourself the Skills to Evaluate and Build Real Blockchain Projects
You have a solid idea and a strong intuition that blockchain is the right tool. But then reality hits: how do you explain what you need to a developer without guessing? How do you know if the person in front of you actually understands blockchain, or is just repeating buzzwords? And if you are the developer, how confident are you that you can design and implement a decentralized system that actually works under real-world conditions?
This course is designed to answer exactly those questions. Whether you are a developer, a technical lead, a manager, a founder, or simply someone who wants to go deeper than surface-level explanations, you will learn how blockchains really work and how to reason about them correctly. No blind trust. No hand-waving.
You will learn how blockchain systems power real solutions across industries such as supply chain traceability, cross-border payments, trade finance, document notarization, identity systems, real estate registries, asset tracking, voting systems, and decentralized marketplaces. You do not need to be a programmer to follow the concepts, but if you are one, you will gain the architectural clarity to build correctly.
This course gives you the know-how to design the core of decentralized systems, understand the tradeoffs, challenge bad designs, and spot weak implementations before they fail. Taught by a senior blockchain architect with real-world experience, it shows you why now is the right moment to build, and how to do it without wasting time or money.
Seats are limited. Early bird pricing is just 15 euro per 2-hour lesson.

Why this moment matters
When the spotlight was on blockchain, it attracted hype, noise, and scams. Now the spotlight is on AI, and that is exactly why this is the moment for serious blockchain and decentralization work to happen quietly and correctly. Forget cryptocurrencies. Blockchain is about coordination, verification, resilience, and trustless infrastructure, things every industry needs, including AI itself. Models, data, provenance, incentives, and governance all break without decentralization. This is your window to stop chasing trends and start architecting the systems that will actually matter for the next decade.
Who this course is for
- Teachers, trainers, and technical content creators
- Product managers, tech leads, engineering managers
- Founders and investors evaluating blockchain projects
- Integrators and solution architects
- Security engineers and auditors
- Software developers (backend, full-stack, systems)
- Smart contract developers who want the base layer to stop being a black box
At a glance
- 30 lessons, 2 hours each
- Concept track: no coding required
- Builder track: implement a working node (Python reference), and you can port it to any stack
- Interoperability: builder-track nodes are designed to interoperate with other students
- Outcome: you will know why each rule exists and what breaks when you remove it
What you build
A blockchain node, from scratch, in the only order that actually works: data structures first, then validation and state transitions, then mining and consensus, then networking, forks, reorgs, syncing, and finally the user-facing tools (API, wallet, explorer).
Each lesson is a 2-hour class with clear outcomes, practical labs, downloadable code, quick checks, and a next-lesson hook.
When it starts
The course starts when either:
- 100 people subscribe, or
- March 2026 arrives
Whatever comes first.
Share your preference
We run two lessons per week. Pick your two preferred days and times.
Most students choose the live sessions. If demand splits across time zones, we can run two live sessions per lesson. Recordings are always available, and we will open extra live Q&A for other time zones.
Test your preparation
Answer 20 random questions to see which track fits you best. You can retake later without seeing the same questions twice.
What the course gives you
You do not leave with opinions. You leave with a correct mental model and a buildable blueprint.
For developers
- A reusable blueprint for a blockchain node: state, transactions, blocks, deterministic hashing
- Validation (stateless and stateful), mempool and fee policy
- Mining and verification, P2P networking, gossip and syncing
- Fork handling and safe reorgs
- Persistence, indexes, snapshots, and an HTTP API + wallet + explorer flow
For leads, PMs, and architects
- A correct mental model of what a blockchain does and what it cannot do
- Vocabulary that maps to real components (mempool, tip, reorg, cumulative work, sync)
- Ability to review proposals and spot missing pieces (replay protection, sync safety, reorg handling)
- Better decision-making around consensus choices and tradeoffs
For security-focused roles
- Structured attack map: replay, double-spend races, eclipse isolation, DoS, fork games
- Concrete defenses: nonce rules, peer selection, rate limits, safe reorg logic
- The habit of designing for adversarial inputs, not good-faith inputs
For integrators and communicators
- End-to-end flow from wallet to node to mempool to block to explorer
- Clear expectations for node APIs and data contracts
- A lesson narrative that makes blockchain teachable without hype
Lessons roadmap (30 lessons)
This roadmap is built for understanding, not hype. You will go from bytes, to rules, to consensus, to networking, to safe reorgs, to real tooling.
Pricing (time-based)
Early bird is a Christmas present: 10 EUR per lesson (300 total) until end of December. January is 15 USD per lesson. February is 30 USD per lesson.

Over the years he has guided startups and enterprises through the full lifecycle: from feasibility and system design to production deployment, audits, and operational hardening. His work spans product strategy, protocol architecture, and go-to-market execution for decentralized platforms in finance, compliance, supply chain, and public-sector use cases.
As a hands-on systems architect, Roberto focuses on practical, verifiable designs that survive real-world constraints. He teaches by building real nodes, not abstractions, and distills complex systems into clear, testable rules. Students leave with the vocabulary and reasoning skills to challenge weak designs and defend strong ones.

What makes this different
- You build the system in the correct order: data, rules, consensus, network, safe reorgs, and tooling
- You learn to reason about adversarial inputs (not good-faith inputs)
- You leave with a blueprint you can port to any language stack
- You gain the vocabulary to challenge vague claims: replay protection, sync safety, fork handling, DoS hardening
FAQ
Do I need to code?
No. You can follow the Concept track with zero coding. If you choose Builder track, you implement a working node using the Python reference code and you can port the design to your preferred stack.
What exactly will I be able to do after?
Explain and build the full lifecycle of a blockchain node: transaction formats, deterministic hashing, stateless and stateful validation, mempool, mining and verification, P2P networking, forks and safe reorgs, persistence and snapshots, sync, and a basic wallet and explorer flow.
When do registrations close?
Registrations close when 100 people subscribe, or in March 2026, whichever comes first. The first live lesson begins shortly after that.
Can I join the next round (June 2026)?
Yes. Leave your email in the waitlist form below and you will be notified.
Do I get a diploma?
You receive a Certificate of Completion issued by Blockchain Zoo that you can share publicly. It is not a government-accredited diploma, but it carries reputational value for employers, clients, and partners.
Are lessons recorded?
Yes. Every lesson is recorded and added to your private library. Live sessions include Q&A, and we schedule extra Q&A blocks if time zones are split.
Can I switch tracks later?
Yes. You can move between Concept and Builder tracks as your confidence grows. The content is aligned, so you can switch without losing context.
What if I miss a live lesson?
You can watch the recording and send questions in advance for the next live Q&A. We also keep a running thread of clarifications for each lesson.
Is the payment refundable?
Payments are final because seats and live scheduling are limited. If you cannot attend live, recordings and additional Q&A sessions are provided.
