Bitcoin, first released as open-source software in 2009, is generally considered the first decentralized cryptocurrency.
The system does not require a central authority, distributed achieve consensus on its state . The system keeps an overview of cryptocurrency units and their ownership. The system defines whether new cryptocurrency units can be created. If new cryptocurrency units can be created, the system defines the circumstances of their origin and how to determine the ownership of these new units. Ownership of cryptocurrency units can be proved exclusively cryptographically. The system allows transactions to be performed in which ownership of the cryptographic units is changed. A transaction statement can only be issued by an entity proving the current ownership of these units.
If two different instructions for changing the ownership of the same cryptographic units are simultaneously entered, the system performs at most one of them. In March 2018, the word “cryptocurrency” was added to the Merriam-Webster Dictionary. The term altcoin has various similar definitions. Decentralized cryptocurrency is produced by the entire cryptocurrency system collectively, at a rate which is defined when the system is created and which is publicly known. As of May 2018, over 1,800 cryptocurrency specifications existed. Most cryptocurrencies are designed to gradually decrease production of that currency, placing a cap on the total amount of that currency that will ever be in circulation. The validity of each cryptocurrency’s coins is provided by a blockchain.
A blockchain is a continuously growing list of records, called blocks, which are linked and secured using cryptography. Blockchains are secure by design and are an example of a distributed computing system with high Byzantine fault tolerance. Decentralized consensus has therefore been achieved with a blockchain. The block time is the average time it takes for the network to generate one extra block in the blockchain.
