🔍 What is Bitcoin?

Bitcoin is a decentralized digital currency that operates without a central authority or banks. It uses peer-to-peer technology to manage transactions and issue new coins through a distributed network.

1, Open-source technology
2, No single owner or controller
3, Transactions validated by the network
4, Enables borderless digital payments

Bitcoin introduced a revolutionary concept — trustless digital transactions powered by cryptography.

🌍 Bitcoin vs Other Cryptocurrencies

While Bitcoin was the first, many other cryptocurrencies have emerged with different mechanisms.

🔹 Ethereum

Uses “Gas” as an internal value mechanism to calculate transaction costs.
Technical Whitepaper (Yellow Paper): https://gavwood.com/paper.pdf

🔹 Litecoin

Uses Proof of Work but with a different hashing algorithm than Bitcoin.

🔹 Ripple

Uses ledger consensus instead of traditional mining.

🔹 NEO

Uses Proof of Stake.

🔹 IOTA

Uses a Directed Acyclic Graph (DAG) instead of blockchain.

Each cryptocurrency differs in mining approach, scalability, and consensus mechanism.

⛏️ How Bitcoin Mining Works

Mining is the process where computers compete to solve cryptographic puzzles to confirm transactions.

1, New block added approximately every 10 minutes
2, Network difficulty adjusts automatically
3, Hash rate indicates total network computing power

Mining secures the network and validates transactions globally.
