Blockchain at Berkeley

Blockchain at Berkeley YouTube Channel Review Guide: Everything You Need to Know (with FAQ)

Want a reliable way to learn crypto in 2025 without getting lost in hype? Wondering if the Blockchain at Berkeley YouTube channel is actually worth your time—and where to start so you don’t waste hours?

I watched the channel like a hawk and mapped what still holds up, what to skip, and who gets the most value. If you want a clear path from “new to crypto” to “building with confidence,” you’re in the right place.

The problem with learning crypto on YouTube

YouTube is amazing for free education—but crypto is a minefield. You’ll find clickbait, outdated tutorials, and lectures that assume you already speak the language. That combo leads to three predictable problems:

• No structure: You bounce between hot takes and half-finished tutorials without a syllabus or checkpoints.


• Outdated tools: Old content still ranks, and commands or gas estimates no longer match 2025 reality.


• Shaky confidence: You think you’ve “learned,” but can’t explain consensus, write a contract safely, or reason about DeFi risks.

There’s a reason this happens. YouTube’s ranking systems historically optimize for watch time and engagement—not curriculum quality (Google/YouTube research on recommendations). And when learning is unstructured, we tend to binge-watch instead of practice, which hurts retention. Evidence-backed study methods—like retrieval practice and spaced review—consistently beat passive watching (Dunlosky et al., 2013; Roediger & Karpicke, 2006).

“Structure beats binge—every time.”

So if you’ve ever watched five hours of crypto videos and still couldn’t explain what a Merkle tree does or how AMMs set prices, that’s not on you. You just didn’t have a plan.

The plan that actually works

Here’s what I’m going to do for you: show you exactly how to use Blockchain at Berkeley’s playlists as a free, structured curriculum. We’ll nail the order to watch, what’s still gold in 2025, what to skip, and where you’ll want fresher tools or code labs. I’ll also answer the questions people ask most so you can move fast without second-guessing every step.

Expect specifics, not fluff. For example, you’ll see why a fundamentals lecture that explains consensus with clear state diagrams is worth more than ten “top 5 altcoins” videos—and how a DeFi talk that walks through slippage math beats yet another token pitch.

How I test and grade channels

I constantly trial crypto learning resources and keep a running scorecard. When I review a channel, I look at:

• Accuracy: Do explanations match how protocols actually work? Are security caveats clear?


• Freshness: Is the content still valid in 2025? If examples are older, do the ideas still map to modern tooling?


• Practical depth: Can a motivated beginner or developer apply this—build a small contract, reason about MEV, or analyze a protocol?


• Beginner fit: Are jargon and math introduced with context? Are slides readable and examples grounded?

I also check pacing (can you watch at 1.25x and still take notes?), slides and repos (linked or easy to reconstruct), and how well lectures stack into a usable roadmap. If a session assumes missing context, I flag it and point to a quick primer.

TL;DR verdict

Short version: The Blockchain at Berkeley YouTube channel is one of the best free crypto education hubs online. It shines for foundations, DeFi, and thoughtful guest lectures that actually teach you how things work. Some older lectures show their age on tooling and ecosystem examples, but the core fundamentals are rock solid. Follow the learning plans I outline next so you don’t fall into rabbit holes.

Curious why this student-led channel punches above its weight—and how to pick the exact playlists that fit your level? That’s where we’re headed next. Ready to see why their approach matters in 2025?

What is Blockchain at Berkeley and why their channel matters

If you’re tired of scattered tutorials and want the closest thing to a real course without paying tuition, this channel is the good stuff. Blockchain at Berkeley is a student-led group at UC Berkeley that teaches credited university courses (DeCal), consults for industry, and publishes those lectures on YouTube. The result is rare on YouTube: structured, up-to-date learning with a syllabus behind it.

“In crypto, the half-life of hype is weeks—the half-life of fundamentals is years.”

The university context matters. UC Berkeley is consistently ranked among the top computer science schools globally, and that academic DNA shows up on the channel—clear definitions, rigorous explanations, and sessions that build on each other rather than chasing headlines.

Quick background on the org

Blockchain at Berkeley runs on three pillars: education, research, and consulting. Their public lectures stem from DeCal courses—student-facilitated classes officially recognized by UC Berkeley (learn about DeCal). That means you’re not watching random webinars; you’re watching lectures that were taught on campus and refined semester after semester.

• Education: Full-semester fundamentals, DeFi theory, and specialty workshops that mirror university pace.


• Research influence: Topics like consensus, cryptography, MEV, and scaling are treated with academic precision.


• Industry ties: They collaborate with teams across the ecosystem, so examples reflect real protocols and tradeoffs—not just toy demos.

What you’ll find on the channel

Expect a mix of full course series and targeted talks. It’s the kind of catalog you can actually build a curriculum from, instead of binge-watching random clips.

• Blockchain Fundamentals (multiple semesters): Consensus, cryptographic primitives, wallets, smart contracts, governance, and safety assumptions—organized week by week.


• DeFi lecture series: AMMs, stablecoin design, oracles, liquidation mechanics, yield, and risk frameworks. Strong on mental models and system design.


• Smart contract sessions: Solidity concepts, contract patterns, common pitfalls, and security considerations. Great for developers to get conceptual clarity before coding.


• Guest lectures and panels: Builders and researchers on scaling (L2s, rollups), zero-knowledge, MEV, security, UX, and governance.


• Workshops: Shorter, focused sessions—think wallet architecture, auditing themes, or protocol-specific case studies.

One thing I appreciate: most series keep a syllabus-like arc. You can watch in order and feel yourself leveling up, which is rare on YouTube.

Who it’s best for

• Beginners: If you want a real foundation without fluff. The fundamentals courses explain why things work, not just how to click buttons.


• Developers: If you need the “why” behind Solidity patterns, threat models, and protocol design before building. Use the lectures for theory, then code with current docs.


• Investors/analysts: If you’re tired of narratives and want first-principles thinking about economic incentives, security assumptions, and real risks.

This matches what we see across the industry: channels that teach fundamentals help people stick around. Reports like Electric Capital’s annual developer studies have repeatedly shown that consistent, educated contributors are a leading indicator of ecosystem health. Translation: strong education creates durable skill, not just short-term hype.

How current is it?

The foundations age well; the ecosystem examples sometimes don’t. Here’s the practical breakdown so you know what to trust at a glance:

• Still gold: Consensus mechanics (e.g., PoS concepts), cryptography basics (hashing, signatures, Merkle trees), security assumptions, and DeFi design principles (AMMs, collateralization logic, oracle risk).


• Check freshness: Tooling and command-line steps from older semesters; gas cost examples; chain-specific details pre-upgrades. For instance, anything pre-2024 won’t account for Ethereum’s EIP-4844 (proto-danksharding) changes, and older smart contract talks won’t mention account abstraction via ERC-4337.


• Use this approach: Learn the concept from the lecture, then validate implementation details against the latest docs (Solidity, Foundry/Hardhat, and protocol repos). Treat old numbers as historical context, not gospel.

The good news: newer uploads cover L2s, ZK, and MEV a lot better, so the channel naturally bridges the gap as you move from fundamentals to current practice.

Want the fastest route through all this without getting lost? Up next, I’ll map the exact playlists worth your time and the order to watch them so you can get results in weeks, not months. Which path should we start with—fresh foundation or builder mode?

The content map: playlists worth your time

I built this as a clean, no-stress route through the Blockchain at Berkeley channel so you can watch in the right order, skip the dead ends, and actually remember what you learn.

“You don’t rise to the level of your goals; you fall to the level of your systems.” — James Clear

Use this as your system.

Beginner path: Blockchain Fundamentals (DeCal)

This is your on-ramp: clear explanations of how blocks are built, why consensus matters, how wallets work, and what smart contracts actually do under the hood. It’s theory that won’t go out of style next cycle.

• Suggested order: Bitcoin and transactions → Ethereum & the EVM → Consensus (PoW, PoS, BFT) → Cryptography basics (hashes, signatures, Merkle trees) → Wallets & addresses → Smart contract intro.


• Quick wins while you watch:
  
  
  
  • Sketch a Merkle proof for a toy dataset (it cements how “proof of inclusion” works).
  
  
  • Trace a single transaction from wallet → mempool → block using a block explorer; label each step in your notes.
  
  
  • Explain block finality to a friend in 60 seconds (use the Feynman technique).
  
  
  
  


• Make tiny quizzes: After each lecture, write five questions and answer them the next day without peeking. Retrieval practice is a cheat code for memory (see the “testing effect” in education research: Roediger & Karpicke, 2006; pair it with spaced review: Cepeda et al., 2006).


• What to treat as timeless vs. dated:
  
  
  
  • Timeless: how consensus works, what cryptographic primitives do, why addresses look the way they do.
  
  
  • Dated: specific gas prices, old wallet UIs, client commands from years back—use the concepts, not the exact steps.
  
  
  
  

Goal here isn’t to memorize slides; it’s to build a mental map of how the whole system clicks together so later topics feel obvious.

Builder path: smart contracts and dev sessions

These workshops lean practical—Solidity mechanics, patterns, and how bugs actually sneak in. Treat them as your concept engine, then code with modern tools while you learn (Foundry/Hardhat today, even if an older lecture shows Truffle).

• Focus topics to prioritize:
  
  
  
  • Solidity language basics and the contract lifecycle (deploy → upgrade patterns → interactions).
  
  
  • Security fundamentals: reentrancy, access control, delegatecall hazards, storage collisions, oracle assumptions.
  
  
  • Gas optimization and storage layout (packing, unchecked math in 0.8+, calldata vs. memory).
  
  
  
  


• Hands-on pairings while you watch:
  
  
  
  • Rebuild a minimal ERC‑20 from the spec; add permit (EIP‑2612) as a stretch goal to understand signatures.
  
  
  • Write a small vulnerable contract, exploit it locally, then patch it using Checks‑Effects‑Interactions and a reentrancy guard. Feel the “before/after.”
  
  
  • Create two invariants for your toy protocol and run them as property tests. Even a simple “sum of balances equals total supply” catches surprises.
  
  
  
  


• Version sanity:
  
  
  
  • Solidity 0.8+ has built‑in overflow checks; if a lecture warns about SafeMath everywhere, translate it to today’s context.
  
  
  • Older syntax (e.g., function visibility defaults, payable quirks) may differ—use the lessons, then confirm in the current Solidity docs.
  
  
  
  


• Learn faster by doing: Active learning consistently beats passive watching in technical fields (meta‑analysis: Freeman et al., PNAS 2014). Don’t move to the next lecture until you’ve coded at least one tiny experiment.

Tip: Commit your experiments in a repo named after the topic (e.g., “reentrancy-lab/01”). Future you will thank you when you revisit a bug pattern.

DeFi and beyond: cryptoeconomics, MEV, and protocol talks

This is where the “why” behind protocols becomes clear—AMMs, stablecoins, oracles, MEV, and risk. It’s candy for PMs, quants, and curious devs who want the mental models that survive market noise.

• Watch order that compounds: AMM basics (x*y=k) → Stablecoins (collateralized vs. algo) → Oracles (design and failure modes) → MEV (searchers → builders → relays) → Risk and incident case studies.


• Mini‑exercises that make it click:
  
  
  
  • Compute price impact: after swapping 10% of pool reserves in a constant‑product AMM, what’s the new price? Write the steps.
  
  
  • Calculate impermanent loss for a 2x price move—seeing the number changes how you think about LP returns.
  
  
  • Open a recent block in a block explorer and look for back‑to‑back swaps that hint at a sandwich; note gas, ordering, and profit path.
  
  
  
  


• MEV reality check: Anything pre‑2022 is valuable history; for the current picture of PBS, order flow, and auctions, cross‑reference with Flashbots docs while you watch.


• Risk muscle: Build a 1‑page checklist from lectures—governance dependencies, oracle updates, upgrade keys, liquidity concentration, fee switches. Apply it to one protocol you use this week.

When you understand why “risk‑free yield” rarely is, you start asking the questions that protect your stack.

Guest lectures you shouldn’t miss

The gold here is fresh context from builders working on scaling, ZK, security, and governance. I use these talks to recalibrate what matters now without getting caught in hype.

• What to listen for:
  
  
  
  • Rollups: data availability choices, shared sequencers, bridging trust—what trade‑off did they pick and why?
  
  
  • ZK: SNARK vs. STARK costs, trusted setup, recursion, prover bottlenecks—note the metrics they track.
  
  
  • Security: incident response timelines, how bounties are designed, and what they’d change if they could rewind one exploit.
  
  
  • Governance: voter participation levers, delegation data, and how proposals avoid capture.
  
  
  
  


• Pick winners fast: Sort by newest first, prioritize “guest” or “panel” sessions, and favor anything recorded in the last 12–18 months.


• Make it stick: For each talk, write “3 numbers, 3 trade‑offs, 3 open questions.” Teaching your notes—even to your future self—boosts retention (the “protégé effect”: Nestojko et al., 2014).

I treat these guest sessions like a live roadmap update from the people shipping the protocols we all use.

So, which of these playlists actually explain complex ideas clearly, and where does the material show its age? I stress‑tested the teaching quality, pacing, and accuracy—let’s unpack that next.

Quality, clarity, and accuracy: my take

If you’re tired of crypto content that shouts instead of teaches, you’ll appreciate the way these lectures breathe. No fluff, no price talk—just clean concepts explained the way a good TA would do it at the whiteboard. Production isn’t flashy, but the signal-to-noise is excellent.

"Clarity compounds. Get the fundamentals right once, and everything else clicks faster."

Expect methodical explanations of what matters: how consensus actually guarantees safety and liveness, how wallets manage keys, why AMMs conserve an invariant, and what a “reentrancy” bug looks like in plain English before it ever touches code. A favorite example: when they explain constant-product AMMs, they don’t just show x*y=k—they walk through how trades move the curve and why liquidity providers earn fees but still face impermanent loss. That kind of framing sticks.

Teaching style and pacing

The delivery leans on whiteboards and clear slides, with crisp definitions followed by concrete examples. It’s the kind of cadence that lets you pause, rephrase in your own words, then hit play without losing the thread. Two practical tips:

• Watch at 1.25x speed if you’re comfortable. Multiple learning studies on playback speed suggest comprehension holds up well up to 1.5x for most students, especially when you pause to take notes.


• Chunk the lectures around slide transitions. The “segmenting” principle from multimedia learning research shows we retain more when content comes in small, meaningful blocks.

In short: steady, academic pacing you can control. It rewards curiosity without wasting time.

What’s aged well vs. what’s outdated

Use the older series for timeless mental models, not for exact commands or tools. Here’s the fast filter I use:

• Still gold
  
  
  
  • Consensus fundamentals: safety vs. liveness, fork choice, finality intuition.
  
  
  • Cryptography basics: hashing, signatures, Merkle trees, commitments.
  
  
  • Architecture: accounts vs. UTXO, contracts as state machines, threat modeling.
  
  
  • DeFi mechanics: AMMs, stablecoin designs, oracle risks, MEV concepts.
  
  
  
  


• Showing its age
  
  
  
  • Tooling references to Truffle/Ganache and web3.js v0.x (use Hardhat or Foundry and ethers.js v6 instead).
  
  
  • Gas talk pre–EIP-1559 and pre-Dencun (base fee and blobs change the reality).
  
  
  • Old ecosystem callouts (ICO-era projects, early DeFi gas costs) that no longer match 2025 conditions.
  
  
  
  

Translation: lean on their explanations for “why,” but confirm “how” with current docs. If a lecture says “Truffle,” I mirror it in Hardhat or Foundry. If it mentions “gas price,” I think in base fee + tip and remember that blob txs exist now.

Slides, assignments, and code

Slides are often linked in video descriptions or course pages and are generally clean: definitions, diagrams, and references you can annotate. Assignments and repos vary by semester, so I plug the gaps with well-known public challenges:

• Concept to code: After a security lecture, run the Ethernaut Reentrancy and Fallout levels, or a couple of Damn Vulnerable DeFi challenges.


• Up-to-date scaffolding: Use Hardhat or Foundry instead of older Truffle flows; swap ganache-cli with anvil.


• Standards and patterns: Generate boilerplate with OpenZeppelin Wizard, then read the actual contracts to connect what you saw in lecture to audited code.

When slides don’t list exercises, I create mini-checkpoints: “Write a minimal ERC-20 with events,” “Model a simple AMM in a spreadsheet,” “Prove to yourself how a Merkle proof works with three leaves.” It keeps momentum high without waiting for a formal assignment sheet.

Common sticking points and how to handle them

• Math-heavy sections feel intimidating
  
  
  
  • Skim a quick primer on hashing, signatures (secp256k1), and Merkle trees before the lecture. Even a 15-minute refresher changes everything.
  
  
  • When BLS or finality shows up, anchor on the goal: “aggregate signatures to reduce bandwidth” and “finality prevents long-range rewrites.” The details land better once the purpose is clear.
  
  
  
  


• Solidity syntax whiplash
  
  
  
  • Do a 30-minute syntax refresh (events, modifiers, errors, receive/fallback). Then replay the example. You’ll retain far more than brute-forcing it live.
  
  
  • Map old patterns to new ones: SafeMath → built-in checked arithmetic (or unchecked blocks), send/transfer → call with checks, storage vs. memory nuances.
  
  
  
  


• DeFi math looks abstract
  
  
  
  • Keep a calculator open. For constant-product AMMs, if price doubles (r = 2), impermanent loss ≈ 2√2/(1+2) − 1 ≈ −5.73%. Seeing the number once makes the concept stick.
  
  
  • Rebuild the AMM state in a spreadsheet: reserves in/out, fee, new price. It makes the curve feel tangible.
  
  
  
  


• MEV terminology overload
  
  
  
  • Watch with a mempool visualizer or read the Flashbots primer for shared vocabulary (front-run, back-run, sandwich, PBS). One page of context defangs a 60-minute talk.
  
  
  
  


• “This command doesn’t work on my machine”
  
  
  
  • Assume the toolchain has moved on. Translate: Truffle → Hardhat/Foundry, web3.js → ethers.js, ganache → anvil. Then re-run.
  
  
  
  

The bottom line: treat older sessions as evergreen ideas and pair them with modern execution. That’s how you get the best of both worlds—university-grade clarity with 2025-ready skills.

Want the easiest way to put this into action without burning out? In the next section, I’ll lay out two simple 30-day plans—one for beginners and one for developers—that turn these lectures into real progress. Which path do you want to take first?

How to build a learning plan from the channel

I like learning plans that actually get you shipping and thinking, not just nodding along. The structure below uses spaced repetition, retrieval practice, and quick feedback loops—methods shown to boost retention and skill-building in multiple studies (testing effect: Roediger & Karpicke, 2006; spacing effect: Cepeda et al., 2006).

"What I cannot create, I do not understand." — Richard Feynman

Beginner 30-day plan

Time budget: 45–60 minutes per day, 5–6 days/week. Your goal isn’t to memorize buzzwords—it’s to build a mental model you can explain to a friend without notes.

• Days 1–10: Core Fundamentals
  
  
  
  • Watch 1 lecture from the Blockchain Fundamentals playlist per day at 1–1.25x speed.
  
  
  • After each lecture, write a 5-question quiz from memory. Then answer it without looking. This is retrieval practice working for you (Roediger & Karpicke, 2006).
  
  
  • Sketch a quick diagram: blocks → transactions → signatures → consensus. Keep it messy and honest.
  
  
  • Deliverable: a one-paragraph “explain-like-I’m-five” note for each core idea (hashing, wallets, consensus).
  
  
  
  


• Days 11–20: Wallets, transactions, basic smart contracts
  
  
  
  • Set up a fresh wallet and send a tiny test transaction on Sepolia (never mainnet funds).
  
  
  • Watch 1–2 sessions on accounts, gas, and smart contract basics. Pause to write down any term you can’t define in your own words; look it up and update your glossary.
  
  
  • Hands-on: deploy a toy contract from a template (you can reference OpenZeppelin to understand interfaces).
  
  
  • Deliverable: a simple “transaction lifecycle” one-pager—what happens from click to confirmation.
  
  
  
  


• Days 21–30: DeFi context so you can read the room
  
  
  
  • Pick 3 DeFi lectures: AMMs, stablecoins, and risk/liquidity. Watch, pause, and write a 1-page summary each.
  
  
  • Mini-lab: Calculate a constant-product AMM price change for a simple trade. A calculator is fine. Understand slippage.
  
  
  • Deliverable: a comparison note—“Order books vs. AMMs: where each shines and why.”
  
  
  
  

Weekly habits that lock it in

• One 30-minute review session using your own quizzes (spacing effect: Cepeda et al., 2006).


• Two “Feynman checks” per week: record a 60-second voice memo explaining a tough concept with no jargon.

Developer 30-day plan

Time budget: 90 minutes/day, 5–6 days/week. You’ll alternate between lectures and building. Think “learn small → build small → break it → fix it.”

• Week 1: Foundations and security instincts
  
  
  
  • Lectures: consensus, contract lifecycle, common vulnerabilities.
  
  
  • Tooling setup: pick Foundry or Hardhat. Add tests on day 1.
  
  
  • Deliverable: a minimal ERC‑20 and ERC‑721 using OpenZeppelin, plus unit tests for mint/transfer/revert paths.
  
  
  • Security reps: run Slither and note every finding. Fix what you can; document what you can’t and why.
  
  
  
  


• Week 2: Patterns, pitfalls, and reviews
  
  
  
  • Lectures: Solidity patterns (pull vs push payments, access control, upgrade gotchas).
  
  
  • Refactor: add role-based access control and pausable modules.
  
  
  • Deliverable: a code review checklist you’ll reuse (reentrancy, unchecked math, external call ordering, auth, invariants).
  
  
  • Stretch: add gas snapshots (hardhat-gas-reporter or Foundry’s gas reports).
  
  
  
  


• Week 3: DeFi mechanics in code
  
  
  
  • Lectures: AMMs, oracles, liquidation/risk.
  
  
  • Fork locally: spin a mainnet fork and simulate a swap + price move. Use a faucet on testnets; never real funds.
  
  
  • Deliverable: a tiny AMM prototype with tests around fees and rounding. Sanity-check against Uniswap docs.
  
  
  • Oracle safety: read Chainlink docs and write one page on “stale data and how to guard against it.”
  
  
  
  


• Week 4: Security drills and polish
  
  
  
  • Lectures: gas optimization, audits, threat modeling.
  
  
  • Fuzz/invariant testing with Echidna or Foundry invariants. Try to break your AMM.
  
  
  • Deliverable: a lightweight audit report of your own repo: summary, severity labels, PoCs, recommended fixes.
  
  
  • Optional: integrate a sandbox like Tenderly for transaction traces.
  
  
  
  

Definition of done at 30 days

• One public repo with tests, a README, and a short audit write-up.


• Notes for 8–12 lectures and two diagrams you could present to a teammate.

Research or advanced track

If you’re optimizing for understanding systems and writing smart critiques, this is your loop: watch, model, simulate, write.

• Focus areas to pick: cryptoeconomics, MEV, scaling (rollups and ZK), protocol governance.


• Model, don’t just read:
  
  
  
  • Recreate AMM curves in a notebook and test fee changes on LP returns.
  
  
  • Prototype a basic auction to see how priority fees and ordering influence MEV.
  
  
  • Compare optimistic vs ZK rollup costs with simple throughput assumptions.
  
  
  
  


• Source material:
  
  
  
  • Channel lectures in these tracks (look for MEV, scaling, and governance sessions).
  
  
  • Flash Boys 2.0 (MEV) and Uniswap documentation for AMM math.
  
  
  
  


• Deliverables:
  
  
  
  • One 2–3 page literature note per topic with “claims vs data” and your counterarguments.
  
  
  • A small public repo with a reproducible experiment (notebook + CSV + README).
  
  
  • One thread or short post summarizing a lecture + your replication result.
  
  
  
  

Tools and tips for learning faster

• Make the videos work for you: watch at 1.25x, hit J/K/L to control pace, and pause to write a 2–3 sentence summary per section.


• Glossary on the fly: keep an Obsidian or Notion page. If you can’t define a term in one sentence, it’s not learned yet.


• Spaced repetition: turn your 5-question quizzes into Anki cards; review 10/day (spacing effect and interleaving help reduce forgetting).


• Whiteboard > copy-paste: redraw key diagrams (Merkle trees, rollup flows). The motor effort makes it stick.


• Build small, daily: 30 minutes of code beats a 3-hour cram. Ship a tiny change every session.


• Safety first: use Sepolia/Holesky testnets, and never touch mainnet keys while learning.


• Accountability loop: post your day’s deliverable (quiz screenshot, code snippet, 60-second explanation) in a study group or repo issues.


• Burnout guard: one rest day per week; on that day, only do a 15-minute review of your Anki deck.

Want me to cut through the common questions—Is it really free, do you get certificates, what’s still relevant in 2025, and how it stacks up against other universities? I’m answering those next, along with the underrated resources people miss. Ready?

FAQ: Real questions people ask about Blockchain at Berkeley’s channel

Is it legit and free?

Yes. It’s a student-led UC Berkeley organization, and the YouTube lectures are free to watch. Think real course content and guest talks from builders—not influencer clips or token promos. You’ll see a university vibe: slides, whiteboards, and structured sequences.

Do I get certificates? Is there homework and code?

No certificate for YouTube viewers—certs are for enrolled Berkeley students. Some series include public assignments or repos in the descriptions, but it’s not guaranteed. When an upload doesn’t include code, I pair the lecture with hands-on practice the same day: build a tiny contract, write tests, or replicate a formula from the DeFi session you watched. That active recall + practice loop is where the learning sticks.

Quick tip: Write 3–5 questions about the lecture from memory, then answer them without looking. Research shows retrieval practice boosts long-term retention more than rewatching. See Karpicke & Roediger (2008) and a summary of spaced repetition effects by Cepeda et al. (2006).

Is the content still relevant in 2025? What’s missing?

Yes on fundamentals and DeFi theory. Consensus, cryptography basics, AMMs, oracles, and risk framing still hold up. What can be dated: specific tooling, gas numbers, and ecosystem references from older semesters. Cross-check hands-on steps against current docs—especially after major changes like EIP-1559, ERC-4337 (account abstraction), and EIP-4844 (proto-danksharding). For ZK and L2 tooling, add a recent workshop or two from official project channels to cover new CLI flags and APIs.

How does it compare to Coursera or MIT/Stanford content?

Depth is comparable on core concepts, but this channel feels more crypto-native and applied. If you want a formal credential, pair it with a MOOC. If you want understanding you can use, the channel stands on its own—especially if you add practice. There’s solid evidence that well-structured videos plus retrieval practice and spaced repetition can outperform passive lecture consumption in knowledge retention (see Karpicke & Roediger, 2008 and Cepeda et al., 2006). The message: watch smart, practice fast.

Can I reuse slides or clips? Any community or contact?

Check each video description for licensing. When unclear, assume personal educational use only. For community and inquiries, use the links on their YouTube About tab—typically a website, email, and socials. Some semesters also spin up public forums or Discords; if it’s not linked, it’s likely for enrolled students only.

Do I need a CS or math background?

No degree required. You’ll do better if you’re comfortable with: basic algebra, probability intuition (for security and MEV), and reading pseudo-code. If math-heavy slides show up, pause and skim a 15-minute primer on hashing, digital signatures, and Merkle trees, then resume. That small reset prevents the “I’m lost” spiral.

Is Solidity still worth learning in 2025?

Yes. EVM chains still hold the majority of DeFi TVL, and most security/audit literature focuses on Solidity patterns. If you’re protocol-curious, add a bit of Rust later for non‑EVM ecosystems; for most builders, Solidity first is the fastest path to shipping something real.

How much time should I budget per week?

Plan 3–5 hours: roughly two lectures at 1.25× speed, plus one small practice block. The practice block is the multiplier—fork a local repo, write a test, or simulate a DeFi formula. Skipping practice makes the same two hours feel like they never happened.

Are there captions and transcripts?

Most videos have YouTube’s auto-captions; some have manual captions. If you need transcripts, use YouTube’s transcript feature from the three-dot menu. It’s handy for skimming definitions and copying formulas into your notes.

Does it cover Bitcoin or just Ethereum?

Both show up. Fundamentals lean on Bitcoin and general blockchain design; developer sessions and DeFi lectures skew EVM/Ethereum because that’s where most open-source examples and audits live. The mix is healthy for understanding trade-offs.

What’s the best way to take notes so I remember this stuff?

• Active recall: Write down questions before you check the answer.


• Spaced repetition: Revisit your notes 1–2 days later, then a week later.


• Worked examples: Recreate the diagram or formula from scratch.

These aren’t study hacks—they’re well-supported learning effects in the literature. Even a lightweight version will pay off.

Why not just learn from random YouTube channels?

Signal-to-noise. University channels are structured and less likely to push outdated tricks. In crypto, bad advice can cost real money or months of confusion. Here you get consistent definitions, reading lists, and guest speakers who actually build things.

One more thing: want a simple “watch this first, then this” list so you don’t overthink it? I’m about to hand you a fast-start checklist and a 30‑day plan—ready to queue your first lecture?

What to watch first and how to keep momentum

I like a simple, low-friction plan that gets you learning today and still excited next week. Here’s the exact order I’d queue up and how I’d keep the pace without burning out.

• 1) Fundamentals first (your “Week 0” boot-up):
  
  
  
  • Intro to blockchain and why it exists
  
  
  • Keys, wallets, and transactions (signatures, nonce, gas basics)
  
  
  • Consensus 101 (Proof of Work/Stake concepts and trade-offs)
  
  
  • Smart contracts overview (what they are, common patterns)
  
  
  • Security basics (common pitfalls and attack surfaces)
  
  
  
  


• 2) Add two DeFi pillars for context:
  
  
  
  • AMMs 101 (how x*y=k works, liquidity, impermanent loss)
  
  
  • Stablecoins 101 (collateralized vs algorithmic, risk and design)
  
  
  
  


• 3) Choose your lane:
  
  
  
  • Builder path: Smart contract workshops, audits, gas, patterns
  
  
  • Research path: MEV, cryptoeconomics, scaling (rollups/ZK), governance
  
  
  
  

That starter set gives you the mental model for everything else. If a later lecture references something unfamiliar, pause and review a relevant fundamentals session. No ego, just reps.

Quick start checklist

• Subscribe and save the core playlists you’ll use this month.


• Pick your 30-day plan and block 45–60 minutes, 4 days a week—same time, recurring.


• For every lecture, write 5 takeaways and 2 open questions you’ll research later.


• End each week with a 20-minute review session: scan your notes, answer last week’s questions, and set next week’s queue.


• Use a “done today” tracker (calendar dots or a simple sheet). Seeing progress keeps motivation high.

Optional: Pair with hands-on practice

• Zero-install path (fastest)
  
  
  
  • Open Remix, pick Solidity, and write a tiny contract (e.g., a counter with increment/decrement).
  
  
  • Compile, run basic functions, then break it on purpose (reentrancy-like pattern) to understand why guards exist.
  
  
  
  


• Local dev (recommended if you’re serious)
  
  
  
  • Use Foundry or Hardhat.
  
  
  • Create a minimal ERC-20 with only mint (owner) and transfer. Write a few tests: minting limits, transfer events, edge cases.
  
  
  
  


• Mini-missions after each lecture
  
  
  
  • After consensus: write a short note comparing PoS safety assumptions vs PoW.
  
  
  • After AMMs: reproduce x*y=k in a spreadsheet and simulate price impact with a few swaps.
  
  
  • After oracles: fork a testnet script and pull a price feed; add a simple require() check using that feed.
  
  
  • After security: list 3 vulnerabilities from a recent incident report and how you’d mitigate each.
  
  
  
  

Momentum tactics that actually work

• Retrieval beats rewatching: Quiz yourself from memory. The “testing effect” consistently outperforms passive review for retention. See the research summaries by The Learning Scientists.


• Space it out: 3–4 shorter sessions per week trump a single cram day. Spaced practice improves long-term recall.


• Interleave topics: Alternate fundamentals, DeFi, and contracts across the week. Interleaving improves your ability to recognize patterns across domains.


• Make it visible: Keep a one-page glossary and a running “unknowns” list. Cross them off as they become knowns.


• Ship tiny wins weekly: One mini-contract, one test suite, or one DeFi model. Momentum loves outcomes.

Pro tip: “Don’t break the chain.” Even 20 minutes counts. Small consistent reps win over heroic sprints.

Templates you can copy

• Lecture notes (repeat each session)
  
  
  
  • 5 takeaways: bullet list, short and sharp
  
  
  • 2 open questions: what to research next
  
  
  • One action: a mini-task to apply that concept today
  
  
  
  


• Weekly checkpoint (15–20 min)
  
  
  
  • What I watched and built
  
  
  • Key insights that changed my mental model
  
  
  • What was confusing (and my plan to fix it)
  
  
  • Next week’s 3–5 items (pre-scheduled)
  
  
  
  

Example first 10 videos to queue

• Intro + history of blockchain (set the why)


• Keys, signatures, and wallets (make a mini glossary)


• Transactions and gas (trace one TX lifecycle)


• Consensus basics (map PoW vs PoS assumptions)


• Smart contracts overview (note key patterns)


• Security fundamentals (list top 5 pitfalls)


• AMMs 101 (simulate a swap; track slippage)


• Stablecoins 101 (categorize risks)


• Oracles and data feeds (sketch attack vectors)


• MEV 101 or ZK intro (choose based on your lane)

Fail-safes for when life gets busy

• Reduce scope, keep the habit: If you can’t watch a full lecture, watch 15 minutes and write 2 takeaways. Win recorded.


• Use a parking lot: When you hit jargon you don’t know, park it in your “unknowns” list and keep rolling. Clear the list in your weekly review.


• Pair up: A buddy or small study group keeps you honest and speeds up unblocking.

Your next step

Line up the first two fundamentals lectures and one DeFi session. Block the time, grab a notebook, and get your first three checkmarks this week. Keep it simple, keep it steady, and you’ll be surprised how quickly the fog lifts.
