✅ DAY 2/30 — How Blockchain Actually Works Yesterday was about why Web3 exists. Today was about how blockchain actually works under the hood. And ngl… this part made everything feel more real. 🧱 First: What Is a “Block”? A blockchain is literally made…
Day 2 Summary
How Blockchain Works
Today I learned how blockchain is structured and why it is secure.
A blockchain is made of blocks that store transaction data. Each block contains a hash, which is a unique digital fingerprint created from the block’s information. Even a small change in the data creates a completely different hash.
Blocks are connected in order, and each block also stores the hash of the previous block. This creates a chain. If someone tries to change an older block, its hash changes, which breaks all the blocks after it. This makes tampering with past data extremely difficult.
Because copies of the blockchain exist on many computers around the world, the network can quickly detect any fake or altered version.

✅ DAY 3/30
(Nodes, Miners & Validators)
So far I learned what blockchain is and how blocks connect.
But today’s big question was:
If there’s no company in charge… who actually runs the system?
Turns out .. regular people and computers around the world.
🌍 Meet the NODES
A node is just a computer connected to the blockchain network.
But not just watching ,
It stores a full copy of the blockchain and helps verify information. Thousands of these nodes exist worldwide.
That means:
• No single server controls everything
• No one can secretly change the records
• If one node goes offline, the network keeps running
• This is what makes blockchain decentralized.
Think of nodes as: 🧠 The memory of the blockchain
👀 The watchers checking everything is correct
✅ What Do Nodes Actually Do?
Nodes:
•Store the entire blockchain history
•Check if transactions follow the rules
•Share information with other nodes
•Reject fake or invalid transactions
So when someone sends crypto, nodes help decide:
“Is this legit or not?”
⛏️ Then Who Adds New Blocks?
This is where miners and validators come in. Different blockchains use different systems to choose who adds the next block.
🧱 System 1: MINERS (Proof of Work – used by Bitcoin)
Miners are special nodes that:
Compete to solve a very hard math puzzle ,The first one to solve it earns the right to add the next block, They get rewarded with crypto, This system is calledProof of Work (PoW).
Why make it hard? Because it prevents cheating, To fake the blockchain, you’d need more computing power than the rest of the world combined. Basically impossible.
Downside: ⚡ Uses a LOT of electricity.
🌱 System 2: VALIDATORS (Proof of Stake – used by Ethereum now)
Ethereum switched to a different system called Proof of Stake (PoS).
Instead of solving puzzles, validators:
Lock up (stake) their own crypto as a deposit, Are randomly chosen to confirm new blocks, Get rewards for being honest, Lose money if they try to cheat...
So instead of “work hard with computers,”
it’s “risk your own money to prove you’re honest.”
Much more energy efficient.
🧠 Why This Matters
Because this is how blockchain stays:
🔐 Secure
⚖️ Fair
🌍 Decentralized
No boss. No company. No central server.
Just: Nodes verifying
Miners or validators adding blocks
Math enforcing the rules

✅ How transactions are verified
✅ The difference between miners and validators
✅ Proof of Work vs Proof of Stake (basics)
This system is lowkey genius fr.

Proof-of-Stake (vs proof-of-work)
Cryptocurrencies use a ton of electricity because of mining. In recent years people started working on a different technique called Proof-of-Stake. Not only does it use less energy, it can also be more secure.

The Talix Landing Page Contest
We’re building Talix, an AI-powered learning platform. We’re looking for a landing page design that is clean enough to put out there
Prizes:
- Winner: 10,000 ETB Cash Prize + 3 months of Talix pro + Featured Credit and Opportunities
- 2nd Place: A custom Domain Name for you.
It's only a landing page, so we expect you to include sections/elements of a modern landing page (Hero Section, CTA, etc.) The design should match our existing App design feels. Hit me up at @sozofe, i will give you the file containing all the things you need and the hosted app playground
Deliverable: Figma is strongly preferred. It would be awesome if you do it in public so that it will be easier to track and see your progress (use #DesignTalix if you decide so), but it's totally optional as long as you deliver on time.
Deadline: 1 week. So you can work on it on weekends too

✅ DAY 4/30
Bitcoin vs Ethereum (They’re NOT the Same)
Before today I thought Ethereum was just “another crypto like Bitcoin.”...Nahhh.
Bitcoin and Ethereum are built on blockchain, but they were designed for different purposes.
🟠 BITCOIN — Digital Money
Bitcoin was created in 2009 to be:
Its main goals:
• Be digital cash
• Work without banks
• Be secure and limited in supply
Bitcoin is focused on one job only: 💰 Sending and storing value....
It’s like digital gold:
• Hard to change
•Reliable
•Not very flexible
•Designed to be simple and secure
Bitcoin’s blockchain is intentionally limited in what it can do.
🔵 ETHEREUM — A Programmable Blockchain
Ethereum came later (2015) with a bigger vision:
Ethereum allows developers to write smart contracts programs that run on the blockchain.
That means Ethereum can power:
•DeFi apps (borrowing, lending, trading)
•NFTs
•Games
•DAOs
•Voting systems
•Marketplaces
So Ethereum isn’t just money…
It’s more like a global computer that anyone can use.
🧠 The Core Difference
Focus: Money
Digital gold
Simple & secure
Limited features
Focus:Applications
Programmable blockchain
Flexible & powerful
Smart contracts + DApps
Bitcoin asks:
Ethereum asks:
⚙️ Tech Difference (Beginner Level)
Bitcoin’s scripting system is very basic on purpose.
This keeps it secure but limits what developers can build.
Ethereum uses a system called the Ethereum Virtual Machine (EVM), which lets code run on the blockchain.
That’s why we can build apps on Ethereum but not really on Bitcoin.
⛽ Gas Fees (Ethereum Thing)
Ethereum transactions cost gas fees because: You’re not just sending money
You’re paying for computation (code execution)
The more complex the action, the more gas it needs.
Bitcoin mostly just processes payments, so its fee system is simpler.
💡 Big Realization Today
Bitcoin = store value
Ethereum = build systems
Bitcoin is like a calculator.
Ethereum is like a smartphone.
Both are powerful just for different reasons.

Day 4 Summary — Bitcoin vs Ethereum
Today I learned that Bitcoin and Ethereum are both blockchains, but they serve different purposes.
Bitcoin was created to be decentralized digital money. Its main goal is to store and transfer value securely, similar to digital gold. It is simple and focused mostly on payments.
Ethereum, on the other hand, is a programmable blockchain. It allows developers to build smart contracts and decentralized applications (DApps), such as DeFi platforms, NFT projects, games, and more.
Conclusion:
Bitcoin is mainly for digital money, while Ethereum is designed to run applications on the blockchain.
