  1. it's gina.
  2. I've decided to discuss block chains And this is an
  3. exciting emerging technology that's shaping the future of data security
  4. and building a future that's going to optimize efficiency for
  5. a lot of different applications.
  6. Mhm. Block chains currently rely on computing power to operate
  7. and with smartphones becoming smarter than ever, even those tiny
  8. computers in our pocket can contribute to the strength and
  9. security of the Blockchain networks.
  10. Mm Not only are parts of the data computation network
  11. mobile but it's also true that enhanced security ultimately allows
  12. for data to become more mobile than ever.
  13. It allows for easy access by the intended users and
  14. not for those who shouldn't be accessing it.
  15. So what exactly is a Blockchain?
  16. It starts with a block of data that has been
  17. given a unique identifier like a digital fingerprint.
  18. If data in the block has changed, the identifier will
  19. also change.
  20. Another block of data is added to that block, forming
  21. a chain.
  22. It lends itself to the previous block by calculating the
  23. previous ones unique identifier along with its own.
  24. If any block of data within the chain is tampered
  25. with, causing its identifier to change the Blockchain will identify
  26. an error because all of the following blocks will be
  27. incorrect in the chain as well.
  28. This is just the first layer of protection that the
  29. Blockchain provides.
  30. Computers are fast enough to simply calculate a new identifier
  31. for each block down the chain until the error resolves,
  32. even if it involves millions of blocks.
  33. Mhm. So the next layer of protection involves slowing down
  34. the creation of a new block.
  35. This provides a means of making the recalculation process too
  36. slow and cumbersome to be effective to be hacked.
  37. Taking this even further, any user is allowed to join
  38. the network that supports the storage and verification of the
  39. Blockchain. Multiple different computer systems are then verifying the accuracy
  40. of the Blockchain independently at this point to tamper with
  41. the data within a block.
  42. All of the following blocks in the chain must be
  43. recalculated for that chain, but also over 50% of the
  44. users verifying the block must have it recalculated.
  45. This makes tampering of data in the chain virtually impossible.
  46. So what do we do with all that awesome security?
  47. The application that has brought this technology to the forefront
  48. in recent years is digital decentralized currency or Cryptocurrency?
  49. Bitcoin is the grandfather But many more coins have come
  50. to market since its 2010 release.
  51. And even governments are looking into using Cryptocurrency to make
  52. transactions more secure.
  53. Yeah. It is also allowed for the protection of digital
  54. artwork from copyright violations.
  55. Non fungible tokens or N.
  56. F. T.
  57. S are gaining ground.
  58. Doesnt mean to protect artists work from fraudulent reproduction or
  59. use. But as I mentioned before, the heart of applications
  60. or the ultra security of the Blockchain networks, this technology
  61. could become an essential part of how we pay taxes,
  62. vote and access healthcare data.
  63. With Blockchain technology, Healthcare data could confidently be secured for
  64. access by the appropriate recipients.
  65. Only streamlining this access translates to better, safer and more
  66. confident care for patients.
  67. Okay, So HRH A for black jeans and what they
  68. hold for the future.
  69. Thanks for watching.
