The Difference Between Blockchain and Cryptocurrency

 🔗 What is Blockchain?

Blockchain is a technology — a special type of database or digital ledger that stores information in blocks, which are linked (or "chained") together in a secure, tamper-proof way.


It is decentralized — no single person or company controls it.


It is transparent — everyone on the network can see the transactions.


It is secure — once information is recorded, it cannot easily be changed.


🟢 Think of blockchain as the platform or infrastructure.


🪙 What is Cryptocurrency?

Cryptocurrency is a digital currency that uses blockchain technology to operate.


Examples: Bitcoin, Ethereum, Litecoin.


It is decentralized and not controlled by any government or bank.


Transactions are recorded on a blockchain.


Cryptocurrencies can be used for buying goods/services or as investments.


🟠 Think of cryptocurrency as one use case of blockchain.

Waits in Playwright: Explicit, Implicit, and Auto

 In Playwright (a powerful end-to-end testing framework), waiting mechanisms help ensure your scripts interact with elements only when they’re ready. Playwright handles waits more intelligently than older tools like Selenium, but understanding the types of waits—Explicit, Implicit, and Auto-waiting—is key for writing reliable tests. 🕰️ Waits in Playwright: Explicit, Implicit, and Auto ✅ 1. Auto-Waiting (Built-in) – Playwright’s Default Behavior What it is: Playwright automatically waits for elements to be actionable before performing actions (like click, type, fill, etc.). This is its most powerful feature. How it works: Waits for the element to be attached to the DOM Waits for the element to be visible Waits for the element to be enabled (not disabled) Waits for stable animation or layout Example: python Copy Edit await page.click('#submit-button') No need for a separate wait — Playwright will wait until the button is ready. Benefits: Reduces the need for manual waits More re...
