![]() ![]() To learn more about Bitcoin, you can consult the dedicated page and the original paper. In addition, anyone can process transactions using the computing power of specialized hardware and earn a reward in bitcoins for this service. The authenticity of each transaction is protected by digital signatures corresponding to the sending addresses, allowing all users to have full control over sending bitcoins from their own Bitcoin addresses. This ledger contains every transaction ever processed, allowing a user's computer to verify the validity of each transaction. This is how Bitcoin works for most users.īehind the scenes, the Bitcoin network is sharing a public ledger called the "block chain". ![]() How does Bitcoin work?įrom a user perspective, Bitcoin is nothing more than a mobile app or computer program that provides a personal Bitcoin wallet and allows a user to send and receive bitcoins with them. Therefore, all users and developers have a strong incentive to protect this consensus. Bitcoin can only work correctly with a complete consensus among all users. In order to stay compatible with each other, all users need to use software complying with the same rules. While developers are improving the software, they can't force a change in the Bitcoin protocol because all users are free to choose what software and version they use. Bitcoin is controlled by all Bitcoin users around the world. Nobody owns the Bitcoin network much like no one owns the technology behind email. As such, the identity of Bitcoin's inventor is probably as relevant today as the identity of the person who invented paper. Just like current developers, Satoshi's influence was limited to the changes he made being adopted by others and therefore he did not control Bitcoin. The Bitcoin protocol and software are published openly and any developer around the world can review the code or make their own modified version of the Bitcoin software. Satoshi's anonymity often raised unjustified concerns, many of which are linked to misunderstanding of the open-source nature of Bitcoin. The community has since grown exponentially with many developers working on Bitcoin. Satoshi left the project in late 2010 without revealing much about himself. The first Bitcoin specification and proof of concept was published in 2009 in a cryptography mailing list by Satoshi Nakamoto. ![]() Who created Bitcoin?īitcoin is the first implementation of a concept called "cryptocurrency", which was first described in 1998 by Wei Dai on the cypherpunks mailing list, suggesting the idea of a new form of money that uses cryptography to control its creation and transactions, rather than a central authority. Bitcoin can also be seen as the most prominent triple entry bookkeeping system in existence. From a user perspective, Bitcoin is pretty much like cash for the Internet. It is the first decentralized peer-to-peer payment network that is powered by its users with no central authority or middlemen. Bitcoin is a consensus network that enables a new payment system and a completely digital money. ![]()
