What is Bitcoin?

Bitcoin is the first and most widely recognized cryptocurrency. It enables peer-to-peer exchange of value in the digital realm through the use of a decentralized protocol, cryptography, and a mechanism to achieve global consensus on the state of a periodically updated public transaction ledger called a 'blockchain.' Practically speaking, Bitcoin is a form of digital money that (1) exists independently of any government, state, or financial institution, (2) can be transferred globally without the need for a centralized intermediary, and (3) has a known monetary policy that arguably cannot be altered. At a deeper level, Bitcoin can be described as a political, philosophical, and economic system. This is thanks to the combination of the technical features it integrates, the wide array of participants and stakeholders it involves, and the process for making changes to the protocol. Bitcoin can refer to the Bitcoin software protocol as well as to the monetary unit, which goes by the ticker symbol BTC. Launched anonymously in January 2009 to a niche group of technologists, Bitcoin is now a globally traded financial asset with daily settled volume measured in the tens of billions of dollars. Although its regulatory status varies by region and continues to evolve, Bitcoin is most commonly regulated as either a currency or a commodity and is legal to use (with varying levels of restrictions) in all major economies. In June 2021, El Salvador became the first country to mandate Bitcoin as a legal tender.

Bitcoin's origin, early growth, and evolution

Bitcoin is based on the ideas laid out in a 2008 whitepaper titled Bitcoin: A Peer-to-Peer Electronic Cash System. The paper detailed methods for "allowing any two willing parties to transact directly with each other without the need for a trusted third party." The technologies deployed solved the 'double spend' problem, enabling scarcity in the digital environment for the first time. The listed author of the paper is Satoshi Nakamoto, a presumed pseudonym for a person or group whose true identity remains a mystery. Nakamoto released the first open-source Bitcoin software client on January 9th, 2009, and anyone who installed the client could begin using Bitcoin. The initial growth of the Bitcoin network was driven primarily by its utility as a novel method for transacting value in the digital world. Early proponents were, by and large, 'cypherpunks' - individuals who advocated the use of strong cryptography and privacy-enhancing technologies as a route to social and political change. However, speculation as to the future value of Bitcoin soon became a significant driver of adoption. The price of bitcoin and the number of Bitcoin users rose in waves over the following decade. As regulators in major economies provided clarity on the legality of Bitcoin and other cryptocurrencies, a large number of Bitcoin exchanges established banking connections, making it easy to convert local currency to and from bitcoin. Other businesses established robust custodial services, making it easier for institutional investors to gain exposure to the asset as a growing number of high-profile investors signalled their interest.
