A core wallet allows users to receive, store, and send digital currency along with the program on or with it. It has the capacity to hold the full blockchain rather than just a portion of it. For instance, Bitcoin transactions are recorded on a blockchain, a global network of computers that keeps track of digital transactions. A wallet is a piece of software that communicates with the network of recordings and enables users to receive, store, and even send their virtual currency. This digital record is always expanding.
