Frequently Asked Questions (FAQ)

What is Bitcoin – what is its primary focus?

Bitcoin is a digital currency primarily focused on peer-to-peer transactions, utilizing the Proof of Work consensus mechanism.

What do miners use to solve complex mathematical problems?

Miners utilize computational power to solve complex mathematical puzzles (Proof of Work). The first miner to find a solution gains the right to add a new block to the blockchain and receives a reward in cryptocurrency, securing the network.

What is DeFi (Decentralized Finance)?

DeFi (Decentralized Finance) refers to financial services built on blockchains without centralized intermediaries. It leverages smart contracts to automate financial operations like lending, borrowing, and trading, giving users complete control over their assets through crypto wallets.
