Crypto is a digital currency, meaning it runs on a virtual network and doesn’t exist in physical form like paper money or coins. Cryptocurrencies are often built using blockchain technology, which provides a secure recordkeeping and processing system for all of their transactions. Cryptocurrency transactions will typically be recorded on a public ledger, called a “blockchain.” That’s a public list of every cryptocurrency transaction — both on the payment and receipt sides. Depending on the blockchain, the information added to the blockchain can include details like the transaction amount, as well as the sender’s and recipient’s wallet addresses. It’s sometimes possible to use transaction and wallet information to identify the people involved in a specific transaction.
