Ethereum Explained for Beginners

💡 How Does Bitcoin Work?

Bitcoin is the world’s first decentralized digital currency. But how does it actually work behind the scenes?

Let’s break it down in 5 simple steps 👇


1️⃣ Bitcoin Is a Digital Currency
It’s completely online — no physical coins.
You can send and receive bitcoin (BTC) like email, but securely and without banks.
Instead of a central authority, Bitcoin runs on a peer-to-peer network of computers called nodes.

2️⃣ Blockchain Is the Ledger
Bitcoin transactions are recorded on a public, tamper-proof ledger called the blockchain.
Think of it as a digital book with pages (blocks) that record every transaction.
Every 10 minutes, a new block of transactions is added to the chain.

3️⃣ Mining Secures the Network
Miners are special nodes that validate and group transactions into blocks.
To do this, they solve complex math problems — this process is called Proof of Work.
The first miner to solve the problem adds the block and is rewarded in BTC.
This process keeps Bitcoin secure, decentralized, and trustless.

4️⃣ Wallets Store Your Bitcoin
A Bitcoin wallet holds your private keys, which allow you to spend your BTC.
Your public key (wallet address) is like your email address.
Your private key is like your password — never share it.

5️⃣ Bitcoin Is Limited and Transparent
There will only ever be 21 million BTC.
Every transaction is visible to anyone via the blockchain.
No central bank or government can print more — Bitcoin is deflationary.

🔐 Why It’s Revolutionary
✅ No middlemen or banks
✅ Borderless and global
✅ Secured by cryptography and code
✅ Controlled by math, not politics

📌 Final Thought
Bitcoin = Digital money + Blockchain + Math-based trust
It’s not just a currency — it’s a movement toward a decentralized financial future.

Handling Frames and Iframes Using Playwright

Handling Frames and Iframes Using Playwright When automating modern web applications, you’ll often come across frames or iframes—HTML elements used to embed another HTML document within the current page. If you're using Playwright for browser automation, knowing how to handle frames properly is crucial for interacting with elements inside them. In this blog, we’ll walk through how to identify, access, and interact with frames and iframes using Playwright with code examples in JavaScript and Python. 🧾 What Are Frames and Iframes? <frame>: Rarely used now; part of the outdated <frameset> HTML structure. <iframe> (inline frame): Embeds another HTML page inside the current one. Common for third-party content like ads, maps, or payment gateways. 🎯 Why Frames Matter in Automation Elements inside an iframe are not part of the main DOM, so trying to interact with them directly will result in errors unless you switch the context to the frame. 🔍 Locating an Iframe in Pla...
