概要

TLDRLes applications décentralisées (dApps) offrent une nouvelle façon d'interagir avec la tecnología blockchain par rapport aux applications centralisées. Contrairement aux applications classiques qui se connectent à des serveurs d'entreprise, les dApps se connectent directement à la blockchain, garantissant de nombreux avantages tels que la transparence, la résistance à la censure et la disponibilité continue. Ces applications sont construites sur des blockchains supportant les contrats intelligents, comme Ethereum. Le contenu décrit des exemples de dApps dans divers domaines tels que la finance décentralisée, le jeu, les marchés et les applications éducatives, soulignant les capacités révolutionnaires des dApps et leur potentiel pour transformer divers secteurs de l'économie numérique. On explore également les avantages et le fonctionnement des smart contracts, essentiels à l'opération des dApps, établissant une base pour l'avenir technologique des applications blockchain.

タイムライン

  • 00:00:00 - 00:05:00

    Les applications décentralisées (ou dapps) fonctionnent de façon similaire aux applications traditionnelles comme Facebook ou Instagram, mais elles se connectent à la blockchain au lieu de serveurs centralisés. Les dapps sont construites sur les réseaux de contrats intelligents, comme Ethereum, mais pas sur Bitcoin. Ces dapps offrent de nombreux avantages, notamment être en open-source ce qui renforce la confiance, et être résistantes à la censure, ce qui les rend indépendantes des gouvernements et entreprises. Elles permettent également de réaliser des opérations sans intermédiaire de confiance grâce aux contrats intelligents qui exécutent automatiquement les accords écrits en code.

  • 00:05:00 - 00:10:40

    Les dapps financières incluent des plateformes comme Aave pour l'emprunt et le prêt, et les échanges décentralisés (DEX) qui permettent le trading sans vérifications d'identité. Il existe aussi des dapps de jeux comme CryptoKitties et Zed Run qui intègrent l'achat et l'élevage de NFTs et des courses de chevaux virtuelles. Les marchés de NFT comme Wearable permettent l'achat, la vente et la création de nouveaux NFT. Finalement, le service ENS simplifie les adresses Ethereum. L'espace des dapps est en pleine expansion et offre des opportunités significatives pour le développement futur.

  • 00:00:00
    you know how your phone can actually
  • 00:00:01
    have a bunch of different applications
  • 00:00:03
    there's facebook and instagram and gmail
  • 00:00:06
    and youtube they're basically all
  • 00:00:08
    applications that run code that was
  • 00:00:09
    created by the company so that you could
  • 00:00:12
    interact with their company
  • 00:00:13
    well a dapp or a decentralized
  • 00:00:15
    application
  • 00:00:16
    is very similar in how it works except
  • 00:00:19
    instead of reporting back to facebook
  • 00:00:21
    servers or tick tock servers
  • 00:00:23
    this app reports back to the blockchain
  • 00:00:25
    you're simply interacting with the
  • 00:00:26
    blockchain through the application
  • 00:00:28
    welcome the whiteboard crypto the number
  • 00:00:30
    one youtube channel for crypto education
  • 00:00:32
    and here we explain topics of the
  • 00:00:34
    cryptocurrency world using analogies
  • 00:00:36
    stories and examples so that you can
  • 00:00:38
    easily understand them in this video we
  • 00:00:40
    are going to explain
  • 00:00:41
    exactly what a dapp or decentralized
  • 00:00:44
    application is
  • 00:00:45
    how they work and why they might hold
  • 00:00:47
    the key to the future of the technology
  • 00:00:49
    first we're going to go over some of the
  • 00:00:50
    benefits of dapps and then we're going
  • 00:00:52
    to cover the different types of them
  • 00:00:54
    including a bunch of specific examples
  • 00:00:57
    the first thing you need to know is that
  • 00:00:58
    dapps can only be built
  • 00:01:00
    on smart contract networks this means a
  • 00:01:03
    blockchain like bitcoin
  • 00:01:05
    cannot utilize dapps bitcoin was
  • 00:01:07
    designed to only allow the sending of
  • 00:01:10
    its native coin
  • 00:01:11
    ethereum however can utilize something
  • 00:01:13
    called smart contracts which is code
  • 00:01:15
    that makes up a program so that it can
  • 00:01:17
    be ran
  • 00:01:18
    to do more complicated things you should
  • 00:01:20
    check out our video on smart contracts
  • 00:01:22
    so that you're not confused throughout
  • 00:01:23
    this video
  • 00:01:24
    but in short they allow two people to
  • 00:01:26
    make an agreement written in code
  • 00:01:28
    so that they don't have to trust a third
  • 00:01:30
    party to follow through they can simply
  • 00:01:32
    just trust the code
  • 00:01:33
    another benefit is that since the code
  • 00:01:35
    is out there to be run
  • 00:01:36
    it is what we call open source which
  • 00:01:38
    means anyone can look at the code
  • 00:01:40
    this allows a lot more trust to be given
  • 00:01:42
    to the application
  • 00:01:44
    we can't really look at how facebook
  • 00:01:45
    recommends us friends to interact with
  • 00:01:47
    or how google knows what we ate for
  • 00:01:49
    dinner
  • 00:01:49
    but with any smart contract we can
  • 00:01:51
    actually look at the code
  • 00:01:53
    and see how it works this is a big
  • 00:01:55
    benefit over centralized applications
  • 00:01:57
    next dapps are also censorship resistant
  • 00:02:01
    and this is a fancy way of saying they
  • 00:02:02
    don't have to answer to governments or
  • 00:02:04
    corporations or even specific people
  • 00:02:06
    if the smart contract is coded to do
  • 00:02:09
    something and it's triggered
  • 00:02:10
    nobody can stop it naturally this is
  • 00:02:13
    good and bad
  • 00:02:14
    but it's really important for financial
  • 00:02:16
    applications this way nobody can control
  • 00:02:18
    your money
  • 00:02:19
    in history governments that have done a
  • 00:02:21
    lot of bad things
  • 00:02:22
    have had the control of their citizens
  • 00:02:24
    money there have also been cases where
  • 00:02:26
    facebook or twitter can actually ban
  • 00:02:28
    or censor certain people based on their
  • 00:02:30
    views or opinions
  • 00:02:32
    a decentralized application will not
  • 00:02:34
    allow this unless it's written
  • 00:02:36
    to another big benefit of decentralized
  • 00:02:38
    applications is that they will
  • 00:02:40
    essentially
  • 00:02:40
    never go offline now there's been times
  • 00:02:42
    where i've actually seen facebook or
  • 00:02:44
    even youtube down
  • 00:02:45
    maybe their servers have a bug or
  • 00:02:47
    there's an outage or they simply just do
  • 00:02:49
    not work it's
  • 00:02:50
    usually for a very short period of time
  • 00:02:51
    because there's a lot of money involved
  • 00:02:53
    but technically the government could
  • 00:02:54
    come in and just shut them down since
  • 00:02:56
    dapps run
  • 00:02:57
    on the blockchain they will actually
  • 00:02:59
    never go down because they are run by
  • 00:03:01
    hundreds of thousands of computers
  • 00:03:03
    all around the world it would be
  • 00:03:05
    infeasible to turn them all off if not
  • 00:03:07
    it's impossible
  • 00:03:08
    so now that you know what makes dapps so
  • 00:03:10
    cool let's get into some examples of
  • 00:03:11
    them
  • 00:03:12
    first off let's start off with financial
  • 00:03:14
    dapps
  • 00:03:15
    there are actually many decentralized
  • 00:03:17
    applications that provide a way for
  • 00:03:19
    people to invest in something called
  • 00:03:21
    decentralized finance decentralized
  • 00:03:23
    finance
  • 00:03:24
    or defy is a new monetary protocol that
  • 00:03:27
    uses blockchain to allow investors to do
  • 00:03:29
    new things
  • 00:03:30
    and even some old things with their
  • 00:03:32
    money with a ton of new benefits
  • 00:03:34
    let's go over some of the ways adapt may
  • 00:03:35
    use your money number one
  • 00:03:37
    borrowing and lending so ave is a
  • 00:03:40
    platform that allows a user to deposit
  • 00:03:42
    their ethereum or matic tokens to
  • 00:03:44
    certain smart contracts whenever you
  • 00:03:46
    deposit these coins and tokens
  • 00:03:47
    you can actually receive an interest
  • 00:03:49
    rate on them allowing you to basically
  • 00:03:52
    invest with them
  • 00:03:53
    ave also lets you borrow tokens
  • 00:03:56
    basically if you have enough collateral
  • 00:03:57
    already deposited so without going too
  • 00:04:00
    much in depth
  • 00:04:01
    this allows you to borrow at different
  • 00:04:03
    interest rates and even create
  • 00:04:05
    specific margin positions if you want to
  • 00:04:07
    learn more about ave we've actually
  • 00:04:09
    created a specific video over this topic
  • 00:04:11
    number two is providing liquidity so
  • 00:04:14
    providing liquidity
  • 00:04:15
    is actually a very complicated idea but
  • 00:04:17
    we're going to make it simple
  • 00:04:18
    in short there is not much money in the
  • 00:04:20
    tokens out there to trade
  • 00:04:22
    so investors can come along buy these
  • 00:04:24
    tokens
  • 00:04:25
    and then invest them in what is called a
  • 00:04:27
    liquidity pool which allows other people
  • 00:04:29
    to trade back and forth using their
  • 00:04:30
    tokens
  • 00:04:31
    the traders pay a small fee that allow
  • 00:04:33
    the investors to earn a return for their
  • 00:04:35
    investment
  • 00:04:36
    it's a win-win situation and number
  • 00:04:38
    three are
  • 00:04:39
    exchanges now as i mentioned allowing
  • 00:04:42
    traders to find a way to actually buy
  • 00:04:43
    and sell their tokens is one of the
  • 00:04:45
    issues in the decentralized finance
  • 00:04:47
    world
  • 00:04:47
    exchanges are decentralized applications
  • 00:04:50
    that allow traders to take some of their
  • 00:04:52
    tokens
  • 00:04:52
    and trade them for another token usually
  • 00:04:55
    with really low fees
  • 00:04:56
    almost instantaneously and without
  • 00:04:58
    needing any background checks or
  • 00:05:00
    identification verification
  • 00:05:01
    that was a mouthful but what it means is
  • 00:05:03
    that you can sell a million dollars of
  • 00:05:05
    ethereum
  • 00:05:06
    without anyone blinking an eye or asking
  • 00:05:08
    any questions by the way these exchanges
  • 00:05:11
    are actually called dexes which stands
  • 00:05:13
    for decentralized exchange
  • 00:05:15
    next up on the menu we have game dapps
  • 00:05:18
    now of course there's going to be games
  • 00:05:20
    i mean programmers are the ones creating
  • 00:05:22
    these daps so they're going to find a
  • 00:05:24
    way to gamify the space
  • 00:05:25
    number one is cryptokitties so
  • 00:05:27
    cryptokitties is a decentralized
  • 00:05:29
    application
  • 00:05:30
    that allow you to buy these little cute
  • 00:05:32
    kittens technically what you are buying
  • 00:05:34
    is the nft data of rights to that
  • 00:05:36
    certain token
  • 00:05:37
    that represents the kitty however the
  • 00:05:39
    fun part of this game
  • 00:05:40
    is that you can actually collect a bunch
  • 00:05:42
    of these kittens and even breed them to
  • 00:05:44
    create more kittens
  • 00:05:45
    in the community the older generation
  • 00:05:47
    kittens are usually the most valuable
  • 00:05:50
    and you can actually sell them for a
  • 00:05:51
    profit or maybe sometimes a loss
  • 00:05:53
    if you play the game long enough even
  • 00:05:55
    more so you can actually rent out your
  • 00:05:57
    kitten to breed with someone else's
  • 00:05:59
    kitten
  • 00:05:59
    as a strange form of passive income on
  • 00:06:02
    the blockchain
  • 00:06:02
    number two is something called zed run
  • 00:06:05
    zed is technically a gambling
  • 00:06:07
    application since you buy nfts that
  • 00:06:09
    represent
  • 00:06:10
    racing horses and then race them every
  • 00:06:12
    horse has specific skills and a point
  • 00:06:14
    system
  • 00:06:15
    also every race is recorded on the
  • 00:06:17
    blockchain so you can see
  • 00:06:18
    all of the races including the races
  • 00:06:20
    your horses have won or lost in
  • 00:06:22
    this game actually went viral for a
  • 00:06:24
    while because it combined the
  • 00:06:26
    psychological pulls of gambling
  • 00:06:27
    with the virality of a blockchain game
  • 00:06:30
    number three
  • 00:06:31
    is basically gambling so just like zed
  • 00:06:33
    is technically a gambling app
  • 00:06:35
    there is an absolute massive list of
  • 00:06:37
    blockchain gambling websites out there
  • 00:06:39
    that are technically
  • 00:06:40
    decentralized applications there are
  • 00:06:42
    daps that allow you to play
  • 00:06:43
    games like poker slots roulette even
  • 00:06:47
    simpler games like
  • 00:06:48
    dice rolling or coin tossing in fact you
  • 00:06:50
    can actually code these applications
  • 00:06:52
    so that the house always wins even if
  • 00:06:54
    it's by one percent but people love
  • 00:06:56
    playing these games
  • 00:06:57
    our next category is tracking apps so
  • 00:07:00
    there are actually many
  • 00:07:01
    applications out there that read smart
  • 00:07:03
    contract data
  • 00:07:04
    and information from the blockchain to
  • 00:07:06
    display it to you technically these are
  • 00:07:08
    decentralized applications but they're
  • 00:07:10
    usually centralized and hosted on a
  • 00:07:12
    single web server
  • 00:07:13
    and in most cases don't require the
  • 00:07:14
    blockchain specific code to work
  • 00:07:16
    however they do read the data from the
  • 00:07:18
    blockchain so we thought they deserved a
  • 00:07:20
    spot on this list so zapify is actually
  • 00:07:22
    a website that collects information
  • 00:07:24
    about wallets that you have
  • 00:07:26
    and the displays it all on one page not
  • 00:07:28
    only will it look at all the major daps
  • 00:07:30
    out there and find out how much money or
  • 00:07:32
    coins you have
  • 00:07:32
    it'll do it for many different networks
  • 00:07:34
    as well zapperfy is one of my favorites
  • 00:07:37
    because it's free to use and i can
  • 00:07:38
    actually see
  • 00:07:39
    a dashboard of my entire blockchain
  • 00:07:41
    portfolio in one place
  • 00:07:42
    now you should know there are many
  • 00:07:44
    different applications like zapify but
  • 00:07:46
    we thought we'd share the one that we
  • 00:07:48
    use
  • 00:07:48
    the next category is marketplaces number
  • 00:07:51
    one
  • 00:07:51
    is cryptokitties again even though we
  • 00:07:53
    put cryptokitties in the game category
  • 00:07:56
    it deserves its own spot in the
  • 00:07:57
    marketplace category
  • 00:07:58
    cryptokitties has proven themselves to
  • 00:08:00
    be an asset that people went crazy over
  • 00:08:03
    in the last few years the price of some
  • 00:08:05
    of these cryptokitties has skyrocketed
  • 00:08:07
    and their dap that allows you to buy and
  • 00:08:09
    sell these nft kitties is paving the
  • 00:08:11
    ground
  • 00:08:12
    for mass adoption number two is wearable
  • 00:08:14
    so wearable and
  • 00:08:16
    air nfts are two marketplaces for other
  • 00:08:18
    nfts
  • 00:08:19
    that allow you to buy sell and even
  • 00:08:21
    create new nft art that you specifically
  • 00:08:23
    can sell
  • 00:08:24
    these platforms or applications
  • 00:08:26
    facilitate the process
  • 00:08:27
    and allow the interaction with the
  • 00:08:29
    blockchain so an everyday person can use
  • 00:08:31
    it
  • 00:08:31
    lastly as an example of a marketplace
  • 00:08:33
    app we have bedali
  • 00:08:35
    bedali is a decentralized application
  • 00:08:37
    that allows you to buy things
  • 00:08:39
    using your crypto one of their main
  • 00:08:40
    products is basically
  • 00:08:42
    gift cards which they can actually
  • 00:08:44
    deliver anonymously and very quickly
  • 00:08:46
    remember whenever you buy stuff with
  • 00:08:48
    crypto in the united states at least
  • 00:08:50
    it is currently reported as a sale and
  • 00:08:52
    because of that you have to pay
  • 00:08:53
    taxes although bedali does not report to
  • 00:08:56
    the irs so the liability is in your
  • 00:08:59
    hands
  • 00:08:59
    you may see what we're saying here
  • 00:09:01
    anyways before we get ourselves into
  • 00:09:03
    trouble
  • 00:09:03
    let's move on to the next category which
  • 00:09:05
    is educational
  • 00:09:06
    so this is still an early announcement
  • 00:09:08
    but we are actually currently developing
  • 00:09:10
    our website into a decentralized
  • 00:09:12
    application where you can complete
  • 00:09:13
    quizzes
  • 00:09:14
    watch videos read articles and gain xp
  • 00:09:17
    through your metamask wallet
  • 00:09:19
    once you have enough experience you can
  • 00:09:20
    then mint limited edition nfts through
  • 00:09:23
    our platform if you're interested leave
  • 00:09:25
    a comment if you want to be an early
  • 00:09:26
    tester
  • 00:09:27
    one last dap that doesn't really fit
  • 00:09:29
    into any of these categories is
  • 00:09:31
    something called
  • 00:09:32
    ens ens stands for ethereum name
  • 00:09:35
    service and we actually have an entire
  • 00:09:37
    video explaining how it works
  • 00:09:39
    in short ens turns those long ethereum
  • 00:09:42
    addresses
  • 00:09:43
    into any address that you want for
  • 00:09:45
    example we actually own
  • 00:09:47
    whiteboardcrypto.eth
  • 00:09:48
    so if you send any of your coins or
  • 00:09:50
    tokens there it'll go to
  • 00:09:52
    our wallet now as we in this video you
  • 00:09:54
    need to know that the categories that we
  • 00:09:56
    listed are just the major ones we wanted
  • 00:09:58
    to share
  • 00:09:58
    this space is incredibly new and there
  • 00:10:01
    are new dapps being built
  • 00:10:02
    every day in fact blockchain developers
  • 00:10:05
    are one of the highest paying jobs this
  • 00:10:07
    year
  • 00:10:07
    simply because there is so much money
  • 00:10:09
    being poured into the space
  • 00:10:10
    and there's a lack of people knowing how
  • 00:10:12
    to code it the sky's the limit and we
  • 00:10:14
    truly believe this space has a lot of
  • 00:10:16
    potential
  • 00:10:16
    for positive growth maybe some of the
  • 00:10:19
    best developers that will ever be
  • 00:10:21
    may use our videos as resources to learn
  • 00:10:23
    and be inspired
  • 00:10:24
    at least that's our goal thank you guys
  • 00:10:26
    so much for watching this video
  • 00:10:28
    we hope that you enjoyed it we really
  • 00:10:30
    hope that you learned something
  • 00:10:31
    and most of all as always we hope to see
  • 00:10:33
    you in the next video
