 Hello and welcome to this short presentation about what is essentially intermediaries My name is Bruno. I'm from the web three foundation and I'm I serve there as the technical educator Explaining what we do and what we are developing from a technical perspective so I mentioned intermediaries and intermediaries are like people or more likely institutions that Make sure that two parties in a deal Keep their word basically the recipient the receiving party has to receive what was arranged and the Sending party has to be punished if they don't keep their promise. That's what intermediaries are an intermediary is basically forward our messages forward our transactions make sure stuff happens on our behalf and Indeed since humans were able to stand on two legs We haven't been able to trust each other and we needed intermediaries to do that for us We needed somebody to kind of make our make sure that other people fulfill our fulfill their promises to us so Let's dive into intermediaries a little bit and define what they really are what they actually do So intermediaries accept messages from outside sources, right? We are the source and we give them a message on what to do. They also Act on these messages once the message is authenticated as really coming from us the origin of the message Then the results of these messages need to be Computed that there has to be some kind of outcome to this message and that outcome has to be stored somewhere, right? So does that sound familiar? It's just a computer, right? It does the exact same thing you put messages in something happens You store the result and then somebody looks at it later on and then uses that as the next input for the next message So why have intermediaries not been replaced by computers by now? Why do we need these intermediaries and institutions if this is really that simple and the answer is authority? well authority and Authorization in a nutshell because a computer does not have the ability or the authorization To decide something on our behalf without our input and this is what these intermediaries actually do So they make decisions when there's any kind of arbitration when there's any kind of disagreement They will decide who's right and who's wrong and this is why we like them This is why we use them today and indeed There are many ways to relay authority and authorization to other people from simple things like payment checks Which are still in use today in some primitive societies like the United States of America to? Elliptic curve cryptography which is a branch of mathematics that lets you prove that you know something without revealing What you know and without letting anybody else impersonate your knowledge later on and We have made Big strides in in forwarding this authorization. We made it so much simpler to forward this authorization to an authority We have usernames and passwords We have two factor authentication to make things a little bit more secured or not very much if you're using sms We have biometrics even which is the least secure of them all but the most practical of them all and With all of these conveniences these these awesome awesome upgrades We now have the ability to send and receive money globally and an instant We have the ability to stalk our crushes or post our baby photos We have the ability to find lost friends and family or argue with strangers online We can become keyboard warriors at the click of a button We can post blogs that reach anybody anywhere at any time and are automatically promoted to everybody else in that same network We can even date online or whatever it is you call that when people use Tinder We can also collaborate an open source code like this was un Unimaginable before people around the world who are Thousands of kilometers apart can work on the same software project without clashes and end up with an awesome product together That's launched without any central oversight that they can all agree on and that's amazing And let's not forget that you can also rent out your apartment without ever actually meeting the person that you're renting the apartment to That's mind-blowingly practical, right? I mean it lets you just earn money for an empty room without having to deal with people. It's great and This intermediary takes care of that dealing with people, right? You don't ever have to meet them Everything happens through the intermediary super great super practical But also it's not a coincidence coincidence that the bank I can resemble is a prison because in any system of perceivably hordeable power somebody is gonna hoard that power and When people abuse that system and when they take the power of the intermediaries that abuse becomes that much worse so now you have Institutions like PayPal and transfer rights who have closed accounts left and right without any kind of justification to people They simply do not like or to people. They are ordered not to like Transfer wise itself has closed my business account with money still in it and refunded some customers overnight and Invented the reason I have yet to hear back from their support two years later Instagram has had its own metadata leakage and allowed people to access private profiles of other people and to stalk them by Using geo tags on their photos Facebook is no stranger to controversy. They have leaks so often. We don't even care anymore Every week something new leaks and we just may whatever Twitter has been no stranger to corporate censorship and to shutting down accounts it disagrees with and that's becoming more and more of a problem on many other platforms as well and Medium itself has built such a walled garden of posts that is impossible to exit practically That they're basically holding your content hostage and using it to drive revenue to the popular bloggers Well, your content is there to drive that traffic and they share nothing with you Tinder and okCupid have both been data-mined Tinder Tinder has leaked through Facebook integrations okCupid was data-mined and some identities were exposed you can Google that It's very interesting case study and GitHub itself has earlier has last year Just closed down some accounts from Iranian developers and caused them to lose months and months of their open source work Just because one fat guy in a cigar told other people I don't like you and because he said I don't like you GitHub said you no longer have your account so the sanctions towards Iran have caused people to lose accounts and a lot of their work Airbnb itself is being hunted in some areas of the world where people are being chased down for By institutions who are under the foot of the hotel lobby and others who do not like this business model Having one central intermediary through all of this through which all of this data goes makes that makes it that much easier to identify These people who need to be hunted down so Power is being hoarded abused and when it's being accessed by people who have no who weren't supposed to access it The abuse is that much worse the hackers can get your data They can use it in different ways and it's all around a very unhealthy system It's becoming a very dangerous system and like Buckminster Fuller said you never change things by fighting existing reality We cannot fix this you to change something build a new model that makes the existing one obsolete So we now have these walled gardens where these institutions do not necessarily trust each other One computer at Facebook doesn't necessarily trust the server state of Twitter There's their their vision of the world doesn't necessarily have to be in sync When somebody has that many likes there, they don't have that many likes there When one post is the truth here, it doesn't have to be the truth there and they're doing this on purpose They have no interest no incentive to agree on content because they rely on Ads and their ads are driven by your rage So they give you clickbait they give you posts that make you upset and they make you drain your focus They make you drain your willpower in one location so that you have no more to drain in their competitors place This is the system that we have built and encouraged They are competing with each other by keeping the walls closed and by keeping the state of the world isolated in each of these Networks and this is harming Users but benefiting them individually. So now we we we bring the blockchain into into matters The blockchain brings as a global state of truth that everybody can check at any moment in time It's just math and if you have a global state of truth that nobody can say is not true Then the systems can trust each other then we have the walled gardens That are becoming on walled the gardens are starting to talk to each other because they have no choice If they lie it is obvious that they lie because we can check that they're lying Mathematically, but also we don't really need these systems anymore because we can trust each other We now are participants of this global system of trust and we can trust that each of us is Telling the truth about what they are saying. So we have commoditized trust we have turned it into an online resource and now we have the internet of value and trust because we have tacked a trust level on to the content that we have and so in the beginning there was the Primitive internet where people were skeptics and told everybody that it would never work then there there was the wonderful read-only Internet with lots of directories and hand handmade directories static webpages Nobody was actually evil then web 2.0 came and this is where we are now walled gardens and insane Practicality so practical. We don't want to leave it even in spite of all the evil that we see Now we have web 3.0. So web 3.0 is the read write trust web It's the verifiable web. It's the web where you can verify a content's truth and that's that's huge That's mega powerful and but but the web 3 is not just Blockchain right these are blockchain apps that I use every day, but it's the web 3 is more than that It's much more than that. So the web 3 is three things. It's linked data It's data that machines have to understand and know how to parse and know how to process Without a translator in the middle without an adapter written by humans that needs to be in place for the machines to understand each other And we've had that since like 2000 or so then there's the distributed data So we need to make sure that all the computers that need the data have the data So that we can make sure that these computers can actually talk and can exchange this data But there's something missing because we've had this since torrents, right? Something is missing and this is where blockchain comes in blockchain adds trust to that data So that now the machines that have the data can make sure that their copy is as legit as everybody else's copy And that the copy coming in is as legit as the one that they expect So now we have the internet that is linked and that is trusted and that is distributed And that's the essence of the web 3.0. This is what we're building at the web 3.0 foundation Web 3.0 is a system of being able to send a message Anywhere anytime to anyone anyhow without fear of censorship or downtime That's all there is to it and that message can be hello in a chat program It can be forbidden content that the Chinese fireball doesn't want you to see or it can be a financial transaction You can send money to anyone anywhere in the world. That's all there is to it So all we want is to make it possible to transfer messages from anywhere to anywhere Now our system is the internet of blockchain in a way Because we are building polka dot and that's a system that allows other blockchains to talk to each other We are not competing with them We are making all of them better by allowing them to to to share their strengths through one common system I don't really have time to go into this diagram, but I would love to explain it later If you grab me Essentially these pink boxes are these chains that are communicating and they're communicating through these central system and these pink lines And in the middle they are the communication messages between the blockchains We have built a system which lets independent and completely unrelated blockchains Securely speak to each other without relays without humans doing the trans Translation and this allows us to pull the greatest strengths of all the independent blockchain Blockchains into one system and makes the web 3.0 possible. So what we are doing with this is we are locking the web open by adding a new infrastructure layer on top of everything that exists right now by Upgrading the system and making the blockchains talk to each other and allowing all the accompanying systems like IPFS the Interplanetary file system or whisper or swarm and all of these other things that are being developed to talk to other blockchains Through this system. We are effectively locking the web open and making it forever Impossible to go back to the dystopian way of aggressive data harvesting Repackaging and selling our own data back to us that we are stuck in in the web 2.0 world So this is essentially what we're doing. Please go to web 3.foundation to find out more if you're if you're interested Grab me afterwards. I would love to explain everything that we do and If you're interested in the practical side of things we have a workshop tonight Substrate workshop substrate is a framework for developing your own blockchain. It can talk to polka dot It's two hours and in two hours you will be developing. You will develop your own blockchain It's free to attend. Just go to this URL We'll have a hands-on workshop bring your laptop. Just make sure you install the prerequisites everything's on this URL And I hope to see you there for a practical introduction of everything that I've talked about here I have a few seconds for questions, which I will take now. Thank you. That's it Yes I've checked out the web 3.0 here. Where where? Oh I've used the web 3.0 applications myself with applications like MetaMask And although I think it's quite innovative one thing that I did know notice was that First applications that were previous not monetized were now monetized because blockchain is a generally monetized platform So what I'm wondering is could blockchain be used for just data without a financial token or coin attached to it Yes, so The the use of your blockchain is entirely up to so the question was could the could applications on the blockchain Be used without a financial incentive involved the blockchain itself No, because you need an incentive on the core layer to keep people participating in the blockchain Otherwise it falls apart but applications on the blockchain itself. Yes, absolutely They can and they do there are many applications that do not have an incentive built-in and that can function perfectly Well by just providing some primitives that you can use in other apps or directly and that do not require any kind of financial Ascentive interacting with the blockchain itself still requires you to pay some transactions That's some details that we can't we don't really have time to go into right now But there are many applications that you do not need to have financial incentive for and that are perfectly suited for for the Blockchain and of course there are many more that are absolutely ill suited for blockchain and 99.9 stuff should never touch a blockchain. So 99.9% just getting that out there, but there are things that are perfectly suited for it and that can and should use it Yeah I think we're out of time. Yeah, any other questions real quick. No, okay. Thank you
