What is blockchain technology?

  • Sasha bought 6 apples
  • Sasha gives Nick 5 apples to divide them between his friends.
  • Nick gives Vita 1 Apple.
  • Nick gives Lana 3 apples to share with her friends.
  • Lana, instead of treating her friends, eats all 3 apples in a fit of hunger during the night, and when Tasha and Margo come to her for the promised apples (because they received information that Nick gave her three apples), Lana is trying to put the blame on Nick and says that he gave her only 1 apple, and the rest he kept for himself. But the entry in the blockchain tells a different story and Tasha and Margo know that Lana has eaten their fruits!
