Udacity’s Blockchain Developer Nanodegree (nd1310) is a 29-hour program in two halves: blockchain fundamentals (how blocks, networks, consensus and wallets work) and smart contract development with Solidity and Hardhat. It ends with two reviewed projects, a blockchain use case evaluation and a collateralized loan smart contract. On 13 October 2026 it showed a single review on Udacity’s page.

What it costs

Udacity sells access by subscription. On 13 October 2026 the program page offered $249 a month, $846 for a four-month bundle (about $212 a month), or $999 to buy only this program. A subscription includes Udacity’s wider catalog. The page also showed a 40% discount banner for new users; the current offer appears at Udacity’s checkout.

For almost everyone with the prerequisites, this is a one-month program. The $999 one-time price is hard to justify for 29 hours of content.

What You’ll Learn

The core program has two courses of about 14 hours each, plus optional refreshers for learners whose JavaScript needs work.

Course 1: Blockchain Fundamentals (about 14 hours)

• Blockchain Basics: Predecessors and Block Structure: the path from the cypherpunk movement to Bitcoin and Ethereum, then block structure, the genesis block and hashing.
• Blockchain Networks and Sharing Information: how peer-to-peer networks and cryptography let nodes share information securely.
• How Blockchain Networks Reach Consensus: proof of work, proof of stake, Byzantine fault tolerance and other mechanisms for validating transactions.
• Blockchain Wallets: key pairs, wallet addresses, signing and encryption, and transactions.
• Blockchain Solutions and Applications: system components, smart contracts, ecosystem use cases, and scaling challenges and solutions.

This course is conceptual. If you only want to understand blockchain rather than build on it, a cheaper course covers similar ground; see the alternatives below.

Course 2: Blockchain with Solidity (about 14 hours)

• Writing Your First Solidity Smart Contract: Ethereum basics, Solidity syntax, setting up a coding environment, and testing and deploying a contract.
• Solidity Design Patterns and dApp Interactions: design patterns, working with time, function modifiers, access control and libraries.
• Going to Production with Smart Contracts: writing and deploying secure contracts, integrating with dApps, Ethereum transactions, and testing with Hardhat in a DeFi context.

Three lessons is a short course for a language as unforgiving as Solidity. It gets you to the point where you can write, test and deploy a contract, but it does not go deep into gas optimization, upgradeable contracts or security auditing. Those are what separate junior smart contract developers from employable ones.

The two projects

• Blockchain Use Case Evaluation: you pick a use case, propose a blockchain solution with diagrams, work through the challenges, and present it in a recorded video. It tests whether you can judge when blockchain makes sense, a useful skill for product or consulting roles.
• Collateralized Loan Smart Contract Development: you develop and deploy an Ethereum smart contract that manages collateralized loans across their lifecycle. This is the technical centerpiece and the project to put on GitHub.

Both projects are graded by a Udacity reviewer against a rubric, and you can resubmit until they pass. Udacity’s project review timeline says reviews often take 48 to 72 hours and up to a week at busy times.

Who teaches it

Udacity lists Guillaume Bibeau (senior staff engineer at MetaMask), Anthony Romagnolo (lead blockchain instructor at Dapp University), Ritika Bharati (technical content developer at Udacity), Mohammad Salim (smart contract software engineer) and Sushmita R. (software engineer at Consensys). Having MetaMask and Consensys engineers involved is a good sign for the Solidity half.

What changed from the older program

Udacity launched its first blockchain Nanodegree in 2018. Older reviews, including the previous version of this page, describe Hyperledger, a supply chain dApp and token standards; none of those are in the current syllabus. Ethereum itself has changed since then: The Merge moved it from proof of work to proof of stake on September 15, 2022. The current nd1310 program is shorter, covers both proof of work and proof of stake, and uses Hardhat for testing. If a review mentions Hyperledger or four projects, it is describing an older version.

Who Should Enroll?

• Web developers who know JavaScript well and want a guided first step into smart contracts.
• Backend or full stack developers who want to understand how dApps interact with contracts before choosing whether to specialize.
• Product managers, analysts and consultants who need to evaluate blockchain proposals: the first course and the use case project fit this goal well.

If you only want to trade or invest in crypto, this program is not for you; see our cryptocurrency courses instead. If you have never programmed, Udacity’s label says Beginner but the prerequisites do not; learn JavaScript first.

The prerequisites, in plain terms

Udacity lists intermediate JavaScript, asynchronous JavaScript with async/await, exception handling and command line basics. In practice, you should be comfortable writing async functions that call an API, handling errors with try and catch, and running npm commands in a terminal. If any of that is shaky, Udacity’s optional Introduction to JavaScript (about 30 hours) and Asynchronous Programming (about 6 hours) sections are included, but they will push the program past one month.

A quick readiness check

1. Write an async JavaScript function that fetches JSON from an API and handles a failed request.
2. Install a package with npm and run a script from the command line.
3. Explain in a sentence what a hash function does.

If the first two are easy, you are ready for the Solidity course. The third is covered in course 1, so it is fine if you cannot answer it yet.

How to become a blockchain developer: where this program fits

1. Programming foundations. JavaScript or TypeScript, Git and the command line. Free paths such as The Odin Project cover this.
2. Blockchain concepts. Blocks, consensus, wallets and transactions. This is course 1 of the Nanodegree.
3. Solidity and tooling. Writing, testing and deploying contracts with Hardhat or Foundry. Course 2 starts this; it does not finish it.
4. Security. Common vulnerabilities, testing and audits. Not covered here; Cyfrin Updraft has free security tracks.
5. A public portfolio. Contracts deployed to a testnet, with tests and documentation, on GitHub.

The Nanodegree covers steps two and the start of step three. Plan the rest separately. Our blockchain developer certification guide covers credential options.

Pros and Cons

Pros:

• Short and focused: 29 core hours fits in one month of subscription.
• Instructors include engineers from MetaMask and Consensys.
• Current tooling: Hardhat for testing and deployment to testnets.
• Two reviewed projects, one conceptual and one technical, with human feedback.
• Optional JavaScript refreshers are included at no extra cost.

Cons:

• Only three Solidity lessons: no security auditing, gas optimization or upgradeable contracts.
• Almost no public reviews (one on Udacity’s page), so outcomes are hard to judge.
• Free resources cover the same Solidity ground in more depth.
• Blockchain hiring is cyclical and smaller than general software development.

What learners say

There is very little program-specific feedback: Udacity’s page shows one review, at five stars. Across Udacity as a whole, Trustpilot showed 4.5 from 3,406 reviews on 13 October 2026. Among the 60 newest, most praised structured lessons and project reviews; the negative ones described project reviews pending for weeks, terminals that stopped working and slow support tickets, and one said newer courses contain mistakes that look AI-generated.

On Reddit, most discussion of Udacity’s blockchain program dates from the 2018 launch of the older version, including an r/ethdev thread urging people not to enroll. That criticism was about a different syllabus. More useful is the path one r/learnprogramming learner described in 2022: JavaScript fundamentals with The Odin Project, then full stack JavaScript, then Udacity’s blockchain course. That is the order we recommend too.

Is the Blockchain Nanodegree Worth It?

Yes, if you are a JavaScript developer who wants a structured, reviewed introduction and you will finish in a month ($249 at list price, less with a new-user offer). The collateralized loan project gives you a deployed contract to discuss, and the fundamentals course is a clear grounding in how blockchains work.

No, if you want to work as a smart contract developer. You will need much more Solidity and security practice than this program offers, and the best material for that is free. Start with Cyfrin Updraft and spend the money on time, not tuition.

How it compares with the alternatives

Cyfrin Updraft says its on-demand courses are free to access, and it pays us nothing; we list it because it is the strongest free option for Solidity. Grider’s course is rated 4.3 from 28,333 ratings with more than 157,000 students. INSEAD’s course, taught by Don and Alex Tapscott, is rated 4.6 from 115 reviews and suits non-developers who want course 1’s material without the price. For broader lists, see our best blockchain courses, Solidity courses and Web3 courses guides, or our Blockchain Council review if you want a certification-style credential.

Turning the loan contract into a portfolio piece

A passed project is a starting point, not a portfolio. After the review, extend the collateralized loan contract: add events for every state change, write tests for edge cases such as late repayment and liquidation, and deploy it to a public testnet with a short README explaining the design. Then compare your code with a security checklist from a free course such as Cyfrin Updraft’s. Showing that you looked for vulnerabilities in your own contract tells an employer more than the certificate does.

Ways to lower the cost

• Finish in one billing period. At 29 hours, one month is realistic if your JavaScript is solid. Fix gaps before you subscribe.
• Check the new-user offer. Udacity showed a 40% banner for new users on 13 October 2026; our links go to Udacity’s checkout, where the current offer appears.
• Ask your employer. Udacity sells business plans, and several recent Trustpilot reviewers took courses through employer training.
• Cancel on time. Cancel once both projects pass; access continues to the end of the paid month.

A one-month plan

Write more tests than the rubric asks for. In smart contract work, tests are the evidence an employer looks for first, and they cost nothing to add.

Frequently Asked Questions

Is the Udacity Blockchain Developer Nanodegree worth it?

It is worth it for JavaScript developers who want a short, structured introduction to blockchain concepts and Solidity, with two projects a reviewer grades, and who can finish in about one month of subscription. It is not worth it if you want deep smart contract development or security skills: free resources such as Cyfrin Updraft go much further, and the program has only one public review on Udacity’s page.

What is a Udacity Nanodegree?

A Nanodegree is Udacity’s name for a multi-course program built around projects that a human reviewer grades against a rubric. You receive a Udacity certificate when every project passes. It is not a college degree or academic credit, and it is sold through Udacity’s subscription.

How long does the Blockchain Developer Nanodegree take?

Udacity estimates 29 hours for the core program: about 14 hours of blockchain fundamentals and 14 hours of Solidity. At 10 hours a week that is about three weeks plus project review. Optional JavaScript refreshers add up to about 38 more hours if you need them.

Do I need to know JavaScript?

Yes. Udacity labels the program Beginner, but its prerequisites are intermediate JavaScript, asynchronous JavaScript with async/await, exception handling and command line basics. Smart contract testing with Hardhat is written in JavaScript, so weak JavaScript will slow you down.

Does the program cover Hyperledger, NFTs or IPFS?

No. Those topics belonged to Udacity’s older blockchain program. The current syllabus covers blockchain fundamentals, wallets and consensus, then Solidity, design patterns, dApp interactions and deploying contracts, with Hardhat for testing.

How much does it cost?

On 13 October 2026 Udacity charged $249 a month, $846 for four months (about $212 a month) or $999 to buy the program outright, and showed a 40% discount banner for new users. At 29 hours, one month on the monthly plan is the cheapest route for most learners.

Can I get a refund?

Udacity’s Terms of Use (updated January 16, 2026) give seven days from your first purchase to cancel for a full refund. After that, fees are not refunded, and canceling a monthly plan keeps access until the end of the paid month.

Is blockchain development still a good career?

It is a smaller and more cyclical market than general software development, and hiring follows crypto market cycles. Solidity developers who understand security are in the strongest position. Treat this program as an introduction, then build and publish your own contracts.

Is the Udacity blockchain certificate recognized?

It is a Udacity certificate, not an industry certification or academic credit. In blockchain hiring, deployed contracts, audited code and public repositories carry far more weight than any course certificate.
