Bitcoin is a decentralized digital currency that allows people to send and receive payments without relying on a central authority such as a bank or government.
It operates on a distributed network of computers and uses blockchain technology to record and verify transactions.
Bitcoin was introduced in 2009 and became the first widely adopted cryptocurrency.

How Bitcoin Works
Bitcoin transactions are processed and verified by a global network of computers.
Every transaction is recorded on a public ledger called the blockchain. This ledger is shared across the network, making it difficult to alter transaction history.
When a user sends Bitcoin, the network verifies that the sender has sufficient funds and records the transaction on the blockchain.
This process allows Bitcoin to function without a central payment processor.
What Is Blockchain?
Blockchain is the technology that powers Bitcoin.
It consists of a chain of blocks containing transaction records. Once information is added to the blockchain and confirmed by the network, it becomes extremely difficult to modify.
This helps maintain the integrity of the transaction history and prevents the same funds from being spent more than once.
Bitcoin vs. Traditional Currency
Bitcoin ≠ Traditional Currency
Traditional currencies are issued and managed by central banks.
Bitcoin is not controlled by a central authority and operates through a decentralized network.

How to Use Bitcoin
To use Bitcoin, a user typically needs:
- A Bitcoin wallet to store and manage funds.
- A Bitcoin address for sending and receiving payments.
- A service or exchange if they wish to buy or sell Bitcoin.
Wallets are available as:
- Mobile applications
- Desktop applications

Practical Implications
Bitcoin transactions can be sent directly between users without involving a traditional bank.
However, users are responsible for securing access to their wallets and recovery information. Losing access credentials can result in permanent loss of access to funds.
Because Bitcoin’s value can fluctuate significantly, it should not be assumed that its market price will remain stable over time.
Summary
Bitcoin is a decentralized digital currency that operates on blockchain technology. It enables peer-to-peer transfers without a central authority and maintains a public record of transactions through a distributed network.
While Bitcoin has become one of the most widely recognized cryptocurrencies, users should understand both its capabilities and limitations before using it for payments or storing value.
