Explain why it is important in moving today’s economy forward, and provide at least two real examples of the chosen core function being changed by blockchain technology today. Then think of three questions you’d like to ask other students and add these to the end of your thread. (block chain revolution text book)- Attached are the core functions – you can write the answer from attached Describe the use case that aligns most closely with your current job role, including how blockchain technology would change things that you currently do in your job. If you are not working in a job role that aligns nicely with a use case presented in chapter 1, describe a job role that you would like to hold after finishing your degree program, and how blockchain technology may affect those job functions.
Modern science fiction films often regard alien visitors as hostile conquerors. From the destructive Martians in War of the Worlds to the White House-blasting invaders in Independence Day, alien species are shown as destructive and ruthless. But unlike their modern counterparts, the aliens in Arthur C. Clarke's Childhood's End peacefully unify the world instead of destroying it. The Overlords are more convincing than modern science fiction invaders because they work to earn the respect of humanity and wish to further man's evolution. Unlike alien invaders in films like War of the Worlds, the Overlords subtly exert their power to earn humanity's respect. When a major power fires a nuclear missile at Karellan's ship, the Supervisor does not take any action to shoot it down. Instead, the world bears witness to the Overlords technical superiority when Karellan's ship emerges unscathed. Knowing that their mightiest weapon is useless against the Overlords, humanity learns to respect their authority. But technological intimidation is not the only method employed by the demon-looking creatures. Karellan does not punish the belligerent nation, instead he "ignored them contemptuously, leaving them to worry over a vengeance that never came" (Clarke 14). By refusing to take action, Karellan's decision was "a more effective, and more demoralizing treatment than any punitive action could have been" (Clarke 14). As the offending government collapses, humanity understands that no means of force will drive the Overlords from Earth. Begrudgingly they accept the Overlords presence. The same cannot be said for the invaders in War of the Worlds though. In the film version of H.G. Wells' novel starring Tom Cruise, alien creatures come to Earth with the purpose of destroying humanity. While the film does not explain the aliens' motivations, they don't make any effort to contact humanity - instead they attack with no reason and encounter military resistance. For an intelligent race with space-faring capability to attack Earth seems far-fetched - more likely an alien visit would be less destructive. It would be more logical for a race with superior technology and intelligence to visit Earth for altruistic reasons rather than destroying humanity. The Overlords serve to protect mankind, not destroy it like the aliens in modern studio films do. Instead of subjugating the human race, the Overlords act more like parents, gently settling man's conflicts. To protect man from himself, the Overlords facilitate the elimination of war, poverty, and crime. But because the Overlords do not use force to improve the world, most men are "only dimly aware that their steadily rising standards of living were due to the Overlords" (Clarke 22). Ironically, the Overlords are only the catalysts for the unified Earth - the world's nations draft the World State charter not the Overlords themselves. If the Overlords crafted their own charter, many people would oppose it. But since the
