Paid Udemy video courses include a certificate of completion when you finish; free courses and practice-test-only courses do not. It shows you did the work, but it is not an accredited qualification. Coursera usually charges for a certificate, issued with the university or company that made the course.

Getting Started with Web3 Development
provider

Getting Started with Web3 Development (2021)

4.2
(3,967 reviews)
bySebastien Arbogast

An 18 hour walkthrough that builds a single Ethereum dapp with Truffle and Ganache, rated 4.2 by nearly 4,000 students who like the structure and grumble about outdated tooling.

Best for: Working developers who want to see how a smart contract, its tests, deployment and a front end fit together end to end.

icon
Pros
icon
Cons
    • Setup shown step by step on Mac, Linux and Windows, with code snapshots before and after each lecture
    • Code is typed live and commands are magnified on screen, which reviewers say makes it easy to follow
    • Covers the whole cycle: contract, unit tests, front end, and deploying to Ganache, private and public test chains
    • Nearly nine in ten of its 3,967 ratings are four or five stars
    • Last updated December 2021; reviewers hit version errors in Truffle, Solidity and web3.js
    • The Truffle 5 section is an add on, not a rewrite, so newer lessons assume files built the old way
    • A recent two star review says Q&A goes unanswered and the instructors push a paid eBook instead

The Complete Solidity Course - Blockchain - Zero to Expert (2022)

4.5
(2,328 reviews)
byLiam Sloane

A slow, beginner-first walk through the Solidity language itself, 191 lectures in Remix with an exercise after each topic, running from variables to inheritance and security patterns.

Best for: Anyone who has never coded and wants Solidity as a first language, taught one small concept at a time.

icon
Pros
icon
Cons
    • Assumes zero programming background, and reviewers confirm it stays slow and careful early on
    • An exercise after each topic, with source code solutions included
    • Covers security patterns, restricted access, inheritance and abstract contracts, not just syntax
    • Light humor that reviewers say makes 17 hours easier to get through
    • Last updated October 2022; one reviewer says it never shows deploying to a real network
    • Advanced sections add code on screen without explaining it, reviewers say
    • One reviewer reports typos and jumps between bits of code in later videos that feel half edited
$79.99 Certificate Length: 16.8h
Blockchain Development on Hyperledger Fabric using Composer
provider

3

Blockchain Development on Hyperledger Fabric using Composer (2020)

4.3
(2,278 reviews)
byRajeev Sakhuja

A clear, well-paced introduction to Hyperledger Fabric development through the now-deprecated Composer framework, still useful for learning concepts and building a proof of concept.

Best for: Developers who already write JavaScript or Java and want hands-on Fabric fundamentals for a proof of concept, not a production system.

icon
Pros
icon
Cons
    • Instructor states up front that Composer is deprecated and spells out exactly who should not enroll
    • Reviewers say explanations are clear, the pace is steady, and the examples actually run
    • 36 quizzes and 3 assignments reinforce the concepts across 13 sections
    • Q&A section and quick instructor replies helped students get past environment setup problems
    • Composer is deprecated and the course dates from 2020, so some scripts and materials break without fixes
    • Environment setup is a known pain point, especially on Windows
    • Later chapters walk through pre-written code rather than building it with you

The Complete NFT Web Development Course - Zero To Expert

The Complete NFT Web Development Course - Zero To Expert (2022)

4.3
(1,671 reviews)
byLiam Sloane

A 24-hour project course that builds an ERC721 NFT marketplace from scratch with Solidity, Truffle, and React, now aging since its last update in 2022.

Best for: Beginners who want to hand-build the ERC721 standard and a React front end step by step, bugs included.

icon
Pros
icon
Cons
    • Every line of code feeds the next step, so the marketplace builds up without throwaway examples
    • Writes ERC721, ERC165, and SafeMath by hand, so students see what OpenZeppelin does underneath
    • Optional Solidity and React crash courses let experienced coders skip ahead
    • Bugs are left in and debugged on camera, which one reviewer says taught him more than clean demos
    • Last updated October 2022; reviewers hit broken Node dependencies and a deprecated Web3 library
    • Marketplace covers minting in depth but skips buy, sell, and transfer flows
    • Slow pace for anyone with coding experience, with basics re-explained in every section

Introduction to Corda Development
provider

5

Introduction to Corda Development (2018)

4.6
(1,350 reviews)
byAustin Moothart

A free, three-hour primer on R3's Corda ledger that has developers build an IOU CorDapp by fixing unit tests, useful mainly as a first step toward Corda certification.

Best for: Java or Kotlin developers who need a quick, free orientation to Corda before reading the official docs or sitting the certification exam.

icon
Pros
icon
Cons
    • Free, and short enough to finish in an evening: 3.3 hours of video across 44 lectures
    • Test-driven format: 14 assignments have students fix failing unit tests until an IOU CorDapp works
    • Reviewers call it well structured, moving cleanly from states and contracts to flows and consensus
    • Rated 4.6 by about 1,350 students, the large majority giving four or five stars
    • Not updated since August 2018; links and node instructions no longer match current Corda docs
    • Assignments lean on Kotlin, and Java learners say the videos give them no path to follow
    • Several reviews call it mostly theory that mirrors the free Corda key-concepts documentation
