Bitcoin 

It's a decentralized digital currency, often referred to as a cryptocurrency. It was created in 2009 by an unknown person or group of people using the pseudonym Satoshi Nakamoto. Bitcoin operates on a peer-to-peer network, allowing users to send and receive payments without the need for a central authority, such as a bank.



Key features of Bitcoin include:


Decentralization: Bitcoin operates on a decentralized network of computers (nodes), which means there is no central authority controlling it. This is achieved through a technology called blockchain, a distributed ledger that records all transactions across the network.


Blockchain: The blockchain is a public ledger that contains a chronological record of all transactions. It is maintained by a network of nodes that validate and confirm transactions through a process called mining.


Mining: Mining is the process by which new bitcoins are created and transactions are added to the blockchain. It involves solving complex mathematical puzzles using computer power. Miners are rewarded with newly created bitcoins for their efforts.


Limited Supply: There is a finite supply of bitcoins. The total supply is capped at 21 million coins, which is designed to mimic the scarcity of precious metals like gold.


Divisibility: Bitcoin is divisible into smaller units, with the smallest unit being a satoshi (named after the pseudonymous creator, Satoshi Nakamoto). One bitcoin is equivalent to 100 million satoshis.


Cryptography: Bitcoin transactions are secured using cryptographic techniques. Private keys, which are secret codes known only to the owner, are used to sign transactions and provide ownership.


Pseudonymity: While transactions are recorded on the blockchain, users are identified by alphanumeric addresses rather than personal information. This provides a level of privacy, but it is not entirely anonymous.


Bitcoin has gained attention and popularity as a form of digital currency and a store of value. It is often used for online transactions and as an investment. However, its price is known for its volatility, and regulatory developments and technological advancements can impact its adoption and value.
