A digital signature behaves like a handwritten signature to mark someone’s agreement to a document or transaction or to prove their identity. A cryptocurrency is a type of digital asset that allows for one party to transfer value from one party to another over the internet without the use of a centralized entity, like a bank.

Instead, the computers participating in the network are tasked with verifying and facilitating each “block” (i.e., entry or transaction) within the chain. In some cases, all the computers work together to verify and facilitate each block action.
