What is Bitcoin?
Bitcoin is a consensus rete di emittenti that enables a new payment system and a completely digital money. It is the first decentralized peer-to-peer payment sistema that is powered by its users with no central authority or middlemen. From a user perspective, Bitcoin is pretty much like cash for the Internet. Bitcoin can also be seen as the most prominent triple entry bookkeeping system per existence.
Who created Bitcoin?
Bitcoin is the first implementation of a concept called “cryptocurrency”, which was first described sopra 1998 by Wei Dai on the cypherpunks mailing list, suggesting the disegno of a new form of money that uses cryptography to control its creation and transactions, rather than a central authority. The first Bitcoin specification and proof of concept was published quanto a 2009 quanto a a cryptography mailing list by Satoshi Nakamoto. http://forum.rollbrettmedia.de/user/93418-rudolf2776/ (clicca per maggiori informazioni forum.rollbrettmedia.de) Satoshi left the project sopra late 2010 without revealing much about himself. The community has since grown exponentially with many developers working on Bitcoin.
Satoshi’s anonymity often raised unjustified concerns, many of which are linked to misunderstanding of the open-source nature of Bitcoin. The Bitcoin protocol and programma are published openly and any developer around the world can review the code or make their own modified version of the Bitcoin programma. 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. As such, the identity of Bitcoin’s inventor is probably as relevant today as the identity of the person who invented paper.
Who controls the Bitcoin rete informatica?
Nobody owns the Bitcoin rete informatica much like no one owns the technology behind email. Bitcoin is controlled by all Bitcoin users around the world. While developers are improving the programma, they can’t force a change per the Bitcoin protocol because all users are free to choose what programma and version they use. Durante order to stay compatible with each other, all users need to use programma complying with the same rules. Bitcoin can only work correctly with a complete consensus among all users. Therefore, all users and developers have a strong incentive to protect this consensus.
How does Bitcoin work?
From a user perspective, Bitcoin is nothing more than a mobile app or cervello elettronico program that provides a personal Bitcoin wallet and allows a user to send and receive bitcoins with them. This is how Bitcoin works for most users.
Behind the scenes, the Bitcoin rete di emittenti is sharing a public ledger called the “block chain”. This ledger contains every transaction ever processed, allowing a user’s cervello elettronico to verify the validity of each transaction. 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. Per addition, anyone can process transactions using the computing power of specialized hardware and earn a reward quanto a bitcoins for this service. This is often called “mining”.
