What is Bitcoin (BTC)?
Bitcoin (BTC) is the world’s first and most widely recognized cryptocurrency, created in 2008 by an anonymous entity using the pseudonym Satoshi Nakamoto. Launched in 2009, Bitcoin was designed as a decentralized digital currency that allows people to transfer value over the internet without the need for intermediaries like banks or payment processors. As the first digital currency to solve the double-spending problem using blockchain technology, Bitcoin laid the foundation for the entire cryptocurrency ecosystem.
Bitcoin operates on a peer-to-peer network where transactions are verified by nodes (computers) through cryptography and then recorded on a public ledger called the blockchain. This decentralized structure means that no single entity controls the Bitcoin network, ensuring transparency, security, and resistance to censorship.
How Does Bitcoin Work?
At the heart of Bitcoin is its blockchain technology—a distributed and immutable ledger that records every Bitcoin transaction ever made. Every time a transaction is broadcasted to the network, miners (specialized computers) compete to solve complex cryptographic puzzles to validate the transaction and add it to the blockchain. This process is called mining and uses a consensus mechanism known as Proof-of-Work (PoW).
Once a miner successfully solves the puzzle, the transaction is grouped with others into a “block” and added to the chain of previous transactions, creating a permanent and secure record. For their work, miners are rewarded with newly minted bitcoins and transaction fees, which provides the incentive to maintain the network.
The Bitcoin network has a fixed supply of 21 million bitcoins, with new coins being issued at a decreasing rate. This cap ensures that Bitcoin remains a deflationary asset, as its total supply will never exceed 21 million.
