Question

By issuing concert tickets on the blockchain, fans can verify transfer of ownership from one digital wallet to another, rather than worrying whether the PDF (or paper) ticket they received was sold to 10 other people. This is an example of how blockchain solves the ____________ problem

Answer 1

The answer is "double-spend"

Step-by-step explanation:

• It is a part of the blockchain network, in which the double costs are used in the case of dislocation and potentially stolen cryptocurrency. The criminal offers the duplicate currency, which is a transfer or may erase the payment. It is twice that many, if not frequently.
• It's not desirable for a certain virtual currency to also be spending more than once, because it can contribute to the interest rates and lack of trust in money, essentially making it worthless. It is not the same virtual currency.
