Originally, bitcoin mining was conducted on the processors, or CPUs, of individual computers, with more cores and greater speed resulting in more profit. This entices cryptominers to keep solving the transaction-related algorithms, supporting the overall system. In return, they are awarded a certain number of bitcoin per block.

One key is stored in a secure location as a backup, another is stored on the user's mobile device and a third key can be stored with a multisignature provider. This greatly decreases the chances of a wallet being accessed if lost or stolen. Multisignature wallets require two or more private keys to authorize transactions. Even when connected to another device, the private keys are never exposed, as signed transactions are completed on the device.
