Cryptocurrency is basically digital money that runs on blockchain technology, and every transaction is recorded on a decentralized network instead of being controlled by a bank or government.

It works by using cryptography to secure transactions, miners or validators to verify them, and digital wallets to store your coins, letting people send, receive, or trade value online safely and transparently.

Step-by-step process: Mining, wallets, and transactions

• New coins are created through mining: Computers solve tough problems to validate blocks and earn new coins.
• Transactions are broadcast: When you send crypto, it gets shared across the network for checking.
• Verification uses proof-of-work or proof-of-stake: Nodes confirm the transaction is real and the sender has enough balance.
• The transaction is added to the blockchain: Once approved, it becomes a permanent, tamper-proof record.
• Your wallet stores the crypto: You receive coins in a digital wallet protected by private keys.
• You trade crypto through apps or exchanges: Most beginners use a crypto platform to buy, sell, or manage their coins.

Blockchain technology explained simply

Blockchain is like a shared digital notebook that everyone can view and verify. Once information is written in it, it can’t be changed, making it secure, transparent, and trustworthy without needing a middleman.

How does Bitcoin transaction confirmation work?

A Bitcoin transaction gets confirmed when miners add it to a new block on the blockchain. Each block added after that gives another confirmation, making the transaction more secure. Most exchanges treat 6 confirmations as fully final.

How does blockchain record transactions?

When you make a transaction, it gets grouped with others, verified by the network, and then added to a new block. That block is locked, linked to the previous one, and becomes part of the permanent chain, making the record secure and tamper-proof.
