  • 00:00:08
    hi my name is serge medellin i'm part of
  • 00:00:10
    the developer advocacy team at hedera
  • 00:00:12
    today i would like to take you through a
  • 00:00:14
    quick demo of how hedera can be used to
  • 00:00:16
    easily and securely issue and operate
  • 00:00:18
    loyalty tokens using hedera token
  • 00:00:20
    service
  • 00:00:22
    distributed ledger technologies came
  • 00:00:23
    with a shiny cool promise of
  • 00:00:24
    tokenization from which loyalty schemes
  • 00:00:27
    can definitely benefit
  • 00:00:28
    dlt-based loyalty points can inherit
  • 00:00:31
    improved security and transparency of
  • 00:00:32
    cryptocurrencies enhance fraud
  • 00:00:34
    prevention and resistance to double
  • 00:00:36
    spending compared to traditional loyalty
  • 00:00:38
    schemes
  • 00:00:39
    however in reality many of the glt
  • 00:00:41
    platforms came with the burden of very
  • 00:00:43
    complex and risky development life cycle
  • 00:00:46
    developers often need to learn a new
  • 00:00:47
    exotic language to write what's called a
  • 00:00:49
    smart contract that describes the token
  • 00:00:52
    a smallest error can lead to losses of
  • 00:00:54
    customer funds that cannot be retrieved
  • 00:00:57
    even more running the app usually has
  • 00:00:59
    high and unpredictable operational fees
  • 00:01:01
    ridiculously so transaction speed and
  • 00:01:03
    overall complexity of implementation
  • 00:01:06
    hedera solves this problem by offering a
  • 00:01:08
    tokenization solution that enjoys the
  • 00:01:10
    benefits of hedera itself like
  • 00:01:12
    predictable and low fees and no need for
  • 00:01:14
    smart contracts
  • 00:01:16
    everything is done through the apis
  • 00:01:18
    wrapped in developer familiar languages
  • 00:01:20
    so a wide range of developers will find
  • 00:01:22
    it really easy to develop on
  • 00:01:24
    hedera on the screen we can see a very
  • 00:01:27
    simple demo showing capabilities of
  • 00:01:30
    creation transfer and management of the
  • 00:01:33
    tokens on hedera using hedera token
  • 00:01:35
    service
  • 00:01:36
    we will use hedera token service to
  • 00:01:38
    create simple loyalty points like
  • 00:01:41
    structure
  • 00:01:42
    users will be able to exchange these
  • 00:01:44
    tokens for different loyalty rewards
  • 00:01:46
    that we will publish in a loyalty
  • 00:01:48
    redemption store
  • 00:01:49
    we will also create a simple nft gift
  • 00:01:52
    card that can be exchanged for a
  • 00:01:53
    specific item in the loyalty redemption
  • 00:01:56
    store
  • 00:01:57
    we will look at the user experience from
  • 00:01:59
    the perspective of three actors an
  • 00:02:02
    issuer entity which creates and
  • 00:02:04
    distributes the tokens and two users
  • 00:02:06
    alice and bob
  • 00:02:08
    we've pre-created hedera accounts for
  • 00:02:10
    them which can we identify by their
  • 00:02:13
    hedera user account ids
  • 00:02:15
    we'll also topped up their accounts with
  • 00:02:17
    some hbar
  • 00:02:19
    which is used as a payment to process
  • 00:02:21
    transactions
  • 00:02:23
    these are the view buttons that
  • 00:02:25
    represent what's called a very
  • 00:02:26
    simplified wallet a view into what token
  • 00:02:29
    users own and user interface to manage
  • 00:02:32
    them the user interface can be changed
  • 00:02:35
    and is just for the demo purposes
  • 00:02:37
    let's look at how easy it is to create a
  • 00:02:39
    token using hedera token service and
  • 00:02:42
    discuss some of the customization of the
  • 00:02:44
    token we offer natively
  • 00:02:48
    the dlt industry currently recognizes
  • 00:02:50
    two main meta types of tokens fungible
  • 00:02:53
    and non-fungible tokens fungibility is
  • 00:02:56
    the ability of a good or asset to be
  • 00:02:58
    interchanged for another of kind
  • 00:03:00
    one us dollar can be easily exchanged
  • 00:03:02
    for another us dollar without much of
  • 00:03:04
    the difference to the owner
  • 00:03:06
    many goods and assets are not
  • 00:03:08
    interchangeable such as owned cars and
  • 00:03:11
    houses so they are non-fungible same
  • 00:03:14
    applies for the tokens fungible tokens
  • 00:03:17
    are a great use case for digital assets
  • 00:03:19
    that display properties of what we
  • 00:03:20
    consider close to the notion of money
  • 00:03:23
    but can have some additional codified
  • 00:03:25
    functionality on top of it like loyalty
  • 00:03:27
    points
  • 00:03:28
    non-fungible tokens often used to
  • 00:03:30
    represent unique items sometimes
  • 00:03:32
    physical sometimes digital for example
  • 00:03:35
    an item in a virtual game digital art or
  • 00:03:38
    a coupon to exchange for a product at a
  • 00:03:40
    supermarket can be implemented as an nft
  • 00:03:44
    let's imagine a scenario where we'd like
  • 00:03:46
    to create a new loyalty program for our
  • 00:03:48
    customers
  • 00:03:49
    every time our customers show up in our
  • 00:03:51
    shops a percentage of purchases goes
  • 00:03:54
    back to the customer's wallets in form
  • 00:03:56
    of loyalty tokens
  • 00:03:57
    these tokens can be exchanged for
  • 00:03:59
    redeemable items on the redemption
  • 00:04:01
    marketplace
  • 00:04:03
    let's start with creating
  • 00:04:04
    a new fungible token representing
  • 00:04:07
    loyalty points for our program
  • 00:04:10
    this token creation wizard will help us
  • 00:04:12
    define the token properties and issue a
  • 00:04:14
    new token
  • 00:04:15
    in reality you would use
  • 00:04:17
    hedera sdk to issue the command to
  • 00:04:20
    create mint and transfer new tokens
  • 00:04:24
    any other token has to have a name and a
  • 00:04:26
    symbol these are used to identify tokens
  • 00:04:29
    among many others in a human readable
  • 00:04:31
    format
  • 00:04:32
    we call our loyalty
  • 00:04:34
    points loyalty
  • 00:04:37
    token
  • 00:04:38
    sample
  • 00:04:40
    and assign it a symbol lts
  • 00:04:46
    next step is to decide on the initial
  • 00:04:48
    supply and if supply can be changed how
  • 00:04:51
    many tokens do we create now can we
  • 00:04:53
    issue more tokens in the future as our
  • 00:04:56
    loyal loyalty program expands we may
  • 00:04:58
    want to have additional tokens in
  • 00:05:00
    circulation compared to the initial
  • 00:05:02
    amount so we will set variable supply
  • 00:05:05
    type with an initial supply of 1 million
  • 00:05:08
    tokens
  • 00:05:14
    we have pre-selected some cool token
  • 00:05:16
    configuration features that hedera
  • 00:05:18
    offers as well
  • 00:05:19
    for example we set the kyc parameter on
  • 00:05:23
    it means that any user who would want to
  • 00:05:25
    receive our loyalty points in their
  • 00:05:27
    account
  • 00:05:28
    first would have to be approved by the
  • 00:05:31
    issuer or issuer delegated authority as
  • 00:05:33
    known
  • 00:05:34
    this can be very helpful in the
  • 00:05:36
    situations where organization has
  • 00:05:38
    reporting requirements on the holders of
  • 00:05:41
    the tokens it created
  • 00:05:43
    another useful feature that we've set is
  • 00:05:45
    an admin key for this token which means
  • 00:05:47
    that the properties of this token can be
  • 00:05:49
    changed over time by departing the
  • 00:05:52
    position in the possession of a special
  • 00:05:54
    admin key
  • 00:05:55
    for example over time we may no longer
  • 00:05:58
    need to have a kyc field requirement for
  • 00:06:00
    the tokens an admin can change this
  • 00:06:03
    property over time
  • 00:06:05
    if this feature isn't needed we don't
  • 00:06:07
    have to set it which means that the
  • 00:06:08
    token is immutable and never can be
  • 00:06:10
    changed
  • 00:06:12
    there are many more other great features
  • 00:06:14
    that hedera token service offers for a
  • 00:06:16
    full list please refer to hedera
  • 00:06:18
    documentation portal available at
  • 00:06:20
    docs.hedera.com
  • 00:06:23
    and now we are about to witness one of
  • 00:06:25
    the hedera's superpowers its insane
  • 00:06:28
    transaction speed
  • 00:06:29
    normally on most other networks we would
  • 00:06:32
    have to wait for somewhere between a
  • 00:06:34
    minute to 15 minutes sometimes for a
  • 00:06:36
    transaction to be confirmed with hedera
  • 00:06:39
    it takes about three seconds to get a
  • 00:06:41
    confirmed and final transaction
  • 00:06:48
    it our loyalty points token is now live
  • 00:06:50
    on the network and is ready for
  • 00:06:52
    distribution to make sure we're not
  • 00:06:54
    making it up let's check hedera explorer
  • 00:06:57
    which constantly monitors the network
  • 00:06:59
    for new transactions and confirms that
  • 00:07:01
    the token were indeed created
  • 00:07:10
    hedera explorers are external observers
  • 00:07:12
    that observe header network and log
  • 00:07:14
    events that are happening there
  • 00:07:17
    think of them as logging and business
  • 00:07:19
    intelligence tools auditability is key
  • 00:07:22
    here we can build business intelligence
  • 00:07:24
    tools around the data because we can
  • 00:07:26
    listen to the events happening to the
  • 00:07:28
    token
  • 00:07:29
    on the ledger
  • 00:07:31
    so awesome we can see that
  • 00:07:33
    the token has been created with that uh
  • 00:07:35
    with the name loyalty token sample and
  • 00:07:39
    symbol lts
  • 00:07:41
    and
  • 00:07:42
    now we need to advertise our program to
  • 00:07:45
    the users
  • 00:07:46
    so we advertise the loyalty program to
  • 00:07:49
    the users that you know you get 10
  • 00:07:51
    cashback from all the purchases and our
  • 00:07:53
    user alice hears about it and decides to
  • 00:07:56
    join the program
  • 00:07:58
    we can see that her initial token
  • 00:08:00
    balance is not available
  • 00:08:02
    and
  • 00:08:03
    she needs to make some purchases to earn
  • 00:08:05
    her loyalty points first she needs to
  • 00:08:08
    apply for the program and subscribe for
  • 00:08:10
    it
  • 00:08:12
    and once she applies for it we can see
  • 00:08:14
    that her initial token balance is zero
  • 00:08:21
    let's imagine that alice goes to our
  • 00:08:23
    e-commerce store and buys some goods for
  • 00:08:25
    one thousand dollars we want to reward
  • 00:08:27
    her with ten percent of the purchase
  • 00:08:29
    total sum in a form of loyalty points
  • 00:08:31
    for example each loyalty point is
  • 00:08:33
    representing one usd so we will send
  • 00:08:36
    alice 100 lts tokens representing 10 or
  • 00:08:40
    1 thousand dollars
  • 00:08:49
    here we are sending 100 tokens to alice
  • 00:08:56
    as we can see the transaction will fail
  • 00:08:58
    by design
  • 00:09:00
    because as you remember we've set the
  • 00:09:03
    kyc field on the token and first we need
  • 00:09:06
    to label alice as a known user
  • 00:09:09
    by the authority and grant
  • 00:09:11
    her account kyc
  • 00:09:14
    this issues a special authorization
  • 00:09:16
    transaction to hedera saying yes i know
  • 00:09:19
    who alice is and i'm okay with her
  • 00:09:21
    getting our loyalty tokens
  • 00:09:27
    now when we send alice 100 lts tokens
  • 00:09:35
    we can see that transaction is
  • 00:09:37
    successful
  • 00:09:38
    and we can see that alice now has a
  • 00:09:40
    total token balance of 100 lts
  • 00:09:44
    tokens
  • 00:09:46
    she now can send these tokens to other
  • 00:09:48
    registered users or use them to redeem
  • 00:09:50
    items on the marketplace
  • 00:09:52
    this is a foundation of a functionality
  • 00:09:55
    rich token that is secure and fast by
  • 00:09:57
    design
  • 00:09:59
    the next step would be to start building
  • 00:10:00
    business logic around the token
  • 00:10:02
    primitive
  • 00:10:03
    let's create our first redeemable item
  • 00:10:05
    [Music]
  • 00:10:09
    for example apple watch that can be
  • 00:10:11
    exchanged for a certain number of lts
  • 00:10:14
    points
  • 00:10:20
    we would like it to be redeemable for
  • 00:10:23
    let's say 50
  • 00:10:25
    loyalty token samples lts tokens
  • 00:10:30
    and now we are about to create a
  • 00:10:32
    redeemable item
  • 00:10:35
    and now it's been added
  • 00:10:40
    now when alice will go to the redemption
  • 00:10:43
    marketplace
  • 00:10:44
    she will see that apple watch is
  • 00:10:46
    available on the redemption marketplace
  • 00:10:48
    and when pressing redeem button
  • 00:10:51
    she will see an option to redeem with 50
  • 00:10:53
    loyalty to sample tokens once she clicks
  • 00:10:56
    this button
  • 00:10:59
    the transaction is issued to the network
  • 00:11:01
    and we can see that her balance went
  • 00:11:03
    down she now has 50 lts instead of 100
  • 00:11:07
    but now she also owns one apple watch
  • 00:11:10
    congratulations alice
  • 00:11:14
    another example i'd like to quickly walk

    you through is a product and gift card
  • 00:11:19
    uh creation
  • 00:11:21
    it works slightly differently as each
  • 00:11:23
    instance of the gift card is unique and
  • 00:11:26
    represents one-to-one redemption value
  • 00:11:28
    we are creating an nft token that our
  • 00:11:31
    customers can exclusively exchange for
  • 00:11:34
    this time let's say
  • 00:11:37
    samsung galaxy watch
  • 00:11:49
    because it's an nft token it can also
  • 00:11:51
    have some unique properties associated
  • 00:11:53
    with it
  • 00:11:55
    so let's create a new template of the
  • 00:11:57
    unique properties that are describing
  • 00:11:59
    the properties of a gift card
  • 00:12:02
    let's say for example it's samsung
  • 00:12:06
    color is white
  • 00:12:09
    blue font color
  • 00:12:17
    also upload the logo
  • 00:12:21
    another field here is metadata storage
  • 00:12:24
    type
  • 00:12:26
    as we are uploading a logo as part of
  • 00:12:28
    our gift card creation process we want
  • 00:12:30
    this image to be stored immutably in
  • 00:12:32
    some form of decentralized storage
  • 00:12:35
    hedera offers its own storage service
  • 00:12:38
    but we also can choose any other
  • 00:12:40
    decentralized storage solution here we
  • 00:12:42
    use a popular file storage protocol
  • 00:12:44
    called ipfs we will use it to upload the
  • 00:12:47
    gift card metadata to
  • 00:12:51
    let's not worry about kyc option for
  • 00:12:54
    this token it means that anyone can hold
  • 00:12:56
    this gift card without our explicit
  • 00:12:58
    approval
  • 00:13:01
    and now we click create
  • 00:13:05
    and again couple of seconds and our gift
  • 00:13:07
    card is created and ready for
  • 00:13:09
    distribution
  • 00:13:10
    this gift card has a unique serial
  • 00:13:12
    number and full ownership history can be
  • 00:13:16
    observed by the external observers and
  • 00:13:19
    it can only be exchanged for the item
  • 00:13:21
    once
  • 00:13:22
    let's go ahead and create a new
  • 00:13:24
    redeemable item in the redemption
  • 00:13:26
    marketplace
  • 00:13:28
    a samsung
  • 00:13:30
    galaxy
  • 00:13:33
    watch
  • 00:13:39
    and now here we can choose whether it is
  • 00:13:42
    whether this item can be exchanged
  • 00:13:44
    either for one gift card or a samsung
  • 00:13:46
    galaxy watch nft
  • 00:13:48
    or
  • 00:13:50
    for 50 loyalty points
  • 00:13:52
    that's pretty cool we can easily create
  • 00:13:54
    marketplaces where different types of
  • 00:13:56
    tokens can be accepted we can do so many
  • 00:13:59
    really really cool things like loyalty
  • 00:14:00
    points per brand and even loyalty point
  • 00:14:03
    exchanges
  • 00:14:09
    for the gift card nft that we've created
  • 00:14:12
    let's imagine we want users to be able
  • 00:14:13
    to buy it rather than earn through
  • 00:14:15
    loyalty points purchases
  • 00:14:17
    let's send this gift card
  • 00:14:21
    to a marketplace and offer users to buy
  • 00:14:25
    this nft for let's say five hbar tokens
  • 00:14:34
    bob always wanted to buy
  • 00:14:37
    samsung galaxy watch so he buys the
  • 00:14:40
    galaxy watch
  • 00:14:41
    nft gift card of the marketplace for
  • 00:14:44
    bypage bar
  • 00:14:50
    and now he has this card in his wallet
  • 00:14:53
    and can confirm that he has it
  • 00:14:55
    and now he can go to the redemption
  • 00:14:57
    marketplace
  • 00:14:58
    and exchange
  • 00:15:00
    a samsung galaxy watch or either 50
  • 00:15:04
    loyalty token sample tokens or one
  • 00:15:06
    samsung galaxy watch token
  • 00:15:09
    which he will do
  • 00:15:13
    congratulations bob you now have a
  • 00:15:15
    samsung galaxy watch and the gift card
  • 00:15:17
    has been burned
  • 00:15:20
    normally it would take very very long
  • 00:15:21
    time to build this functionality and
  • 00:15:23
    make it safe and secure and easy to
  • 00:15:25
    manage with cedar it's secure fast and
  • 00:15:28
    auditable by design the tokens have full
  • 00:15:31
    traceability into ownership and
  • 00:15:33
    transfers and are never at risk of
  • 00:15:35
    double spend
  • 00:15:37
    if you'd like to run this demo yourself
  • 00:15:39
    it is available as an open source
  • 00:15:40
    project on github under hashgraph
  • 00:15:44
    hedera hds demo in a branch called
  • 00:15:47
    loyalty demo
  • 00:15:49
    this repo has detailed instructions on
  • 00:15:51
    how to set everything up and in no time
  • 00:15:53
    you will be up and running
  • 00:15:55
    i hope this quick demo inspired you to
  • 00:15:57
    create your own loyalty scheme solutions
  • 00:15:59
    and we there are really looking forward
  • 00:16:01
    to hearing about your ideas thank you
  • 00:16:14
    you
