Blockchain is a public, decentralized, and tamper-proof distributed ledger technology. It works like a โdatabaseโ that everyone in the world can view and verify at the same time, specifically designed to record transactions, data, or events โ ensuring information is authentic, trustworthy, and permanently preserved.
๐งฉ Decentralized: No need for banks or intermediaries; data is maintained by global users
๐ Transparent: Anyone can view the contents of the ledger
๐ Immutable: Once written, data cannot be altered or deleted
โ๏ธ Block-based: Information is grouped into โblocksโ and linked chronologically
Blockchain is the underlying technology behind cryptocurrencies like Bitcoin and Ethereum.
Cryptocurrency is a digital asset built on blockchain technology, secured by cryptographic algorithms. It can be used for payments, investments, transfers, and also for running on-chain applications and smart contracts.
Bitcoin (BTC) ๐ : The worldโs first cryptocurrency, considered โdigital goldโ
Ethereum (ETH) ๐ฃ: Supports smart contracts and decentralized applications (DApps)
Stablecoins (USDT, USDC) ๐ต: Pegged to fiat currency, maintaining stable value
Meme Coins (e.g., DOGE, PEPE) ๐ถ: Community-driven with entertainment and hype

๐ High market volatility: Prices fluctuate sharply due to policy, supply-demand, and market sentiment
