The electrum wallet is a secure and free wallet that allows people to store bitcoin more quickly and easily. Bitcoin transactions are kept on a digital record, known as the blockchain, and is maintained by thousands of people around the world. This digital record is growing larger every day and in 2016, it exceeded 100 gigabytes. A wallet is software that interacts with the network of recordings (blockchain) and lets users receive, store, and send their digital money. The benefit of an electrum wallet is that it doesn’t have to download and maintain the entire massive blockchain file.
