  9. 9. Use cases ● Cryptocurrency. ● Voting. ● Lotteries. ● Crowdfunding. ● Energy Trading. ● Patents.
  10. 10. Disadvantages of Blockchain ● Scalability. ● Performance capacity. ● Storage limits. ● Integration challenges with corporate legacy systems. ● There is no Administrator or Support Team to help you. (Logical Consequence.) ● Documentation convulsed (Blame the hype).
