Open-source peer-to-peer (P2P) money and the grandfather of all cryptocurrencies.

Bitcoin is a decentralized digital currency, without a central bank or single administrator, that can be sent from user to user on the peer-to-peer bitcoin network without the need for intermediaries. Transactions are verified by network nodes through cryptography and recorded in a public distributed ledger called a blockchain.

Bitcoin is the first open-source cryptocurrency project actually deployed and used widely. Bitcoin inspired most cryptocurrencies created afterward, and many are simple clones without any relevant addition. It was created in 2009 by the mysterious Satoshi Nakamoto, whose real identity is still unknown. The main application of the Bitcoin network is the Bitcoin cryptocurrency, used to transfer value with no central authority. Bitcoin works with peer-to-peer software, which enables participants to issue Bitcoins and manage transactions collectively and automatically. Bitcoin is self-regulating, and inflation is limited. The maximum number of emitted Bitcoins capped at 21 million units.

Key Concepts and Features


Unlike traditional currencies, Bitcoin operates on a decentralized network of computers. This means no single institution or government has control over the Bitcoin network.

Blockchain Technology

Bitcoin transactions are recorded in a public ledger known as the blockchain. This technology ensures transparency and security, preventing fraud and unauthorized transactions.


Bitcoin mining is the process by which new bitcoins are entered into circulation. It is also the method used to secure the network and verify transactions. Mining involves solving complex computational puzzles.


Bitcoin wallets are digital tools, that allow users to store, send, and receive bitcoins. Wallets secure bitcoins with cryptographic keys.

Anonymity and Transparency

Bitcoin offers a unique blend of anonymity and transparency. While all transactions are publicly recorded in the blockchain, the identities of the parties involved are encrypted.


Bitcoin is known for its price volatility. Its value can rapidly increase or decrease over a short period of time, making it a risky investment for some.

Legal and Regulatory Issues

The legal status of Bitcoin varies by country. While some governments have embraced it, others have imposed restrictions or outright bans.

The goal of Bitcoin is to provide a secure, decentralized, and efficient way of conducting transactions without the need for traditional financial institutions. It represents a groundbreaking shift in the concept of money and has the potential to change the financial landscape globally.
