Unlike traditional currencies, cryptocurrencies exist only as a shared digital record of ownership, stored on a blockchain. When a user wants to send cryptocurrency units to another user, they send it to that user’s digital wallet. The transaction isn’t considered final until it has been verified and added to the blockchain through a process called mining. Cryptocurrency is a digital payment system that doesn’t rely on banks to verify transactions. It’s a peer-to-peer system that can enable anyone anywhere to send and receive payments.

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. Cryptocurrencies run on a distributed public ledger called blockchain, a record of all transactions updated and held by currency holders.

This is what Bitcoin miners are doing, running numbers through a cryptographic algorithm until they guess the valid NONCE. If a counterfeiter attempts to create a fake record of cryptocurrency, the computers in the network will disagree with the change in an old block. The fake record will be invalid and not recorded in the network. Bank transfers also require a centralized party to deduct the funds from the sender’s account and deposit them into the recipient’s.

For cryptocurrencies, this is the transaction history for every unit of the cryptocurrency, which shows how ownership has changed over time.
