Foundations
Why blockchain exists at all — the digital-trust problem and the leap from ledger to chain.
Not a bootcamp, not a buzzword tour. A six-module course built rule by rule, ending in an exam and a verifiable credential.
From the original problem of digital trust to the working machinery of consensus, contracts, and certification.
Why blockchain exists at all — the digital-trust problem and the leap from ledger to chain.
Hashing, blocks, chain linking, wallets, transactions. The mechanics behind every move.
Proof-of-Work, Proof-of-Stake, BFT — how a network of strangers agrees on a single truth.
Code as agreement. From a simple transfer rule to the full application stack.
Layer-1s, Layer-2s, stablecoins, exchanges, oracles — how the real-world system is wired.
Where the protocol is heading, where the jobs are, and how to keep learning past the exam.
Designed alongside universities and L&D teams. Verifiable, not just printable.
It taught me blockchain as a protocol — not as a market. Honest, structured, no hype.
I tried four other courses before this. DLTC is the one I'd actually recommend to a non-engineer.
A clear, exam-backed credential my hiring panel can read at a glance.
The foundational course in the DLTC catalogue. By the end of BF101 you don't memorise blockchain — you understand it.
Six modules covering the full stack — foundations, consensus, smart contracts, ecosystem, future & careers. Concludes with a 100-question certification exam.
Six modules. One exam. A certificate worth showing.
