The reference to the action of extracting minerals from the Earth is due to the fact that bitcoin miners employ electricity and computing hardware to generate, or ‘extract’, bitcoins from the system. Much like the world’s resources, the number of bitcoins in this algorithmic mine is not infinite but restricted to a limited supply of 21 million coins. Every transaction is accompanied by the digital signature of the coin’s owner. These electronic signatures are sequentially logged in a decentralised, public database called the “block chain”, so each bitcoin has a specific history of digital signatures from the moment it is mined throughout the chain of its transactions. Bitcoin founders favoured the model of distributed computing as opposed to relying on a trusted third party to overcome the double-spending issue that digital currencies are exposed to as non-physical entities. Miners are required not only to generate bitcoins, but also to verify transactions, which means that the lack of a central authority is compensated by a distributed system of self-verification operated by the community of users. This is also the reason why the system of transactions is public, so that it can be accessed by anyone for verification purposes.
