Blockchain: Societal Impact

  • 0:05 - 0:07
    I think non-financial use cases of
  • 0:07 - 0:09
    blockchain are just emerging the biggest
  • 0:09 - 0:11
    such application currently are nfts or
  • 0:11 - 0:13
    non-fungible tokens which represent
  • 0:13 - 0:15
    unique assets things like Collectibles
  • 0:15 - 0:18
    primarily today but there's been an
  • 0:18 - 0:20
    explosion of representing other types of
  • 0:20 - 0:22
    assets things like carbon credits real
  • 0:22 - 0:24
    estate Securities and those kinds of
  • 0:24 - 0:26
    things fundamentally you can think of
  • 0:26 - 0:30
    blockchain as creating more efficient
  • 0:30 - 0:33
    usage or exchanges in almost any Arena
  • 0:33 - 0:36
    one way to use blockchain is to track
  • 0:36 - 0:39
    energy and and how it's used throughout
  • 0:39 - 0:41
    a grid and being able to then help
  • 0:41 - 0:44
    people figure out how to use it much
  • 0:44 - 0:45
    more efficiently
  • 0:45 - 0:48
    any time where there's like a contract
  • 0:48 - 0:50
    the participants they need some level of
  • 0:50 - 0:52
    trust right and usually we bring in
  • 0:52 - 0:53
    lawyers to do that and it's great
  • 0:53 - 0:55
    lawyers are an awesome solution to that
  • 0:55 - 0:56
    they're also an expensive solution to
  • 0:56 - 0:58
    that blockchains can create situations
  • 0:58 - 0:59
    they can't solve every problem but they
  • 0:59 - 1:01
    can create situations where we don't
  • 1:01 - 1:03
    necessarily need a lawyer to be involved
  • 1:03 - 1:05
    because things that the lawyer would
  • 1:05 - 1:07
    take care of can happen on the
  • 1:07 - 1:09
    blockchain in a way that everyone can
  • 1:09 - 1:11
    trust currently when we upload photos or
  • 1:11 - 1:12
    videos we don't actually have ownership
  • 1:12 - 1:14
    over that data so there's a huge
  • 1:14 - 1:16
    opportunity in terms of how do we
  • 1:16 - 1:18
    communicate with people that we love but
  • 1:18 - 1:21
    also how do we create online
  • 1:21 - 1:23
    what excites me most about blockchain is
  • 1:23 - 1:25
    the opportunity to deal with the wealth
  • 1:25 - 1:27
    Gap blockchain enables opportunity
  • 1:27 - 1:29
    because in this space we get to
  • 1:29 - 1:32
    de-identify ourselves and now I'm able
  • 1:32 - 1:34
    to interact with people anonymously or
  • 1:34 - 1:37
    pseudo anonymously with just as a series
  • 1:37 - 1:39
    of numbers my public key and I can
  • 1:39 - 1:42
    participate in any type of use cases
  • 1:42 - 1:44
    that I want without having that
  • 1:44 - 1:46
    regulation preventing me simply because
  • 1:46 - 1:49
    you know I'm of a particular demographic
  • 1:49 - 1:52
    or a particular gender My Hope for the
  • 1:52 - 1:55
    future of blockchain is that we find
  • 1:55 - 1:58
    ways to solve problems that we haven't
  • 1:58 - 2:00
    been very good at solving Financial
  • 2:00 - 2:02
    inclusions an obvious one blockchain
  • 2:02 - 2:05
    technology either by itself will solve
  • 2:05 - 2:09
    this problem or it will push governments
  • 2:09 - 2:13
    to put in more sensible regulation to
  • 2:13 - 2:16
    have more sensible policies on access
  • 2:16 - 2:18
    that'll solve the problem the thing that
  • 2:18 - 2:20
    keeps me up at night that I'm really
  • 2:20 - 2:21
    worried about is that we will wind up
  • 2:21 - 2:23
    whether accidentally or deliberately
  • 2:23 - 2:26
    rebuilding the same biases that we have
  • 2:26 - 2:28
    in our existing system
  • 2:28 - 2:30
    foreign
  • 2:31 - 2:33
    there definitely are environmental
  • 2:33 - 2:35
    impacts when it comes to blockchain
  • 2:35 - 2:38
    technology with Bitcoin it's proof of
  • 2:38 - 2:40
    work and proof of work requires energy
  • 2:40 - 2:42
    consumption but the value that Bitcoin
  • 2:42 - 2:44
    brings is much higher than that energy
  • 2:44 - 2:46
    consumption the environmental impacts
  • 2:46 - 2:50
    are disastrous in the case of the proof
  • 2:50 - 2:52
    of work Technologies that's Bitcoin as
  • 2:52 - 2:54
    an example so proof of stake is another
  • 2:54 - 2:56
    form of consensus system we have
  • 2:56 - 2:59
    stakeholders that stake on a on a
  • 2:59 - 3:02
    blockchain to say that this block is
  • 3:02 - 3:04
    valid so using proof of stake we're
  • 3:04 - 3:06
    actually not expending any electricity
  • 3:06 - 3:08
    usage a lot of people believe that it's
  • 3:08 - 3:10
    it's less decentralized so I think
  • 3:10 - 3:11
    you're going to see blockchain reducing
  • 3:11 - 3:13
    its own carbon footprint meanwhile
  • 3:13 - 3:15
    providing Technologies and abilities
  • 3:15 - 3:17
    that will help improve things outside of
  • 3:17 - 3:20
    the blockchain space
  • 3:20 - 3:21
    I believe that crypto currency in
  • 3:21 - 3:23
    blockchain are going to continue to grow
  • 3:23 - 3:25
    and be widely adopted it's true that it
  • 3:25 - 3:26
    goes through Cycles so sometimes we'll
  • 3:26 - 3:28
    see a massive run-up and then a
  • 3:28 - 3:30
    correction but if you zoom out over
  • 3:30 - 3:32
    these from one cycle to the next it
  • 3:32 - 3:34
    continues to grow at a really rapid Pace
  • 3:34 - 3:36
    my biggest concern with blockchain
  • 3:36 - 3:39
    technology is that it's developing very
  • 3:39 - 3:41
    fast but the regulators and governments
  • 3:41 - 3:44
    don't really understand it they don't
  • 3:44 - 3:46
    know how to regulate it they will
  • 3:46 - 3:50
    eventually but short term they don't and
  • 3:50 - 3:52
    it's important to agree across countries
  • 3:52 - 3:54
    not just in one country it's already
  • 3:54 - 3:57
    become a an underlying layer for lots of
  • 3:57 - 3:59
    systems and applications worldwide and
  • 3:59 - 4:01
    so it's pretty difficult to at this
  • 4:01 - 4:03
    point stop using blockchains do I think
  • 4:03 - 4:05
    decentralized permissionless open
  • 4:05 - 4:07
    networks are here to say I certainly
  • 4:07 - 4:09
    hope so and I think Bitcoin demonstrated
  • 4:09 - 4:11
    that they are at least that one seems to
  • 4:11 - 4:14
    be over a decade in existence will the
  • 4:14 - 4:16
    new one survive it's really anybody's
  • 4:16 - 4:18
    guess it's impossible to know for any
  • 4:18 - 4:20
    new thing we need a lot of evidence to
  • 4:20 - 4:22
    believe that it's really going to be the
  • 4:22 - 4:23
    next big thing and in the case of
  • 4:23 - 4:24
    blockchain we just don't have that
  • 4:24 - 4:27
    evidence yet blockchain's helping push
  • 4:27 - 4:29
    the technology it's pushing ideas it's
  • 4:29 - 4:32
    pushing competition but sometimes the
  • 4:32 - 4:36
    first mover isn't the one who wins
