Description

Weiwu Zhang, CTO, Blockchain Architect, Co-Founder Alphawallet and AlchemyNFT project , His topic is : Token Negotiation, Why Universal Login isn’t Working — This Might.

A

Good, um so I'm online, um thank you, everybody! um This is, will and I'm from alpha wally why universal login uh isn't working, and this one might um so up to this year.

A

um I can, in the previous year and every year before periods here a little bit like in parallel universe, in the sense that if you build web3 website, it's usually targeting web3 audience, you are building d5 or you're, building a dial and if you build web 2 well, there's no reason to use web3 technology between web 2 and web 3 is only happening this year and the most prominent connecting point is something um in the line of universal login, where the user up 2 and web three websites uh with their ethereum address or some kind of um identifier, and that um enables um webster web websites to use so to say- and it's also decentralizing the web a little bit, because now the users can take their identity into their own control and they don't have to be concerned for someone deleting their identity or leaking their password.

A

Before I go into that technology, I wish to step back a little bit and talk about. Why are we doing web 3 in the first place?

A

The way I see it, the reason.

A

Is because centralized web talks? Innovation, that's the first reason. So if you have a new idea or a new website, it won't work without participating in the centralized and second is confidentiality issue. The website knows everything about you and third, is that competition is about who has a data, so without data and technology innovation in point.

A

Will universal login solve these problems and this is a screenshot I take. I took just a few hours on the left side. There is um steam app. This is the map store on the left side on the right side is indigala, which is also a computer games. I logged into both website and you can see on the left side. The website is presenting uh highly customized choices.

A

Advertisement for some computer game hardware, which every gamer should be interested, but only a little interested and a few random games. That is not up to my taste so well, that is a platform, and it not only sells me game. It also rents my game on the right side in the gala. It's only a store front.

A

Indigala does not have data needed to compete.

A

If we add universal login, let's say users can log in with their ethereum address on both websites. What will change? Frankly, I think nothing will change the advantage and the steam will still be a platform.

A

They didn't get us where we wanted for decentralized web now, if you think what um what can prove the um what is most most differentiating point of web three, I don't think his ethereum address, I think, is a token so for this game it will change. There are a few things we can. We can. We can change by using tokens. So first we can tokenize the products.

A

I effectively own the game. Token ownership talk that allows me when I log into indiegala the website on the right side to share my so that they can make better suggestions, and, secondly, I can- I should be able to tokenize my identity and, more specifically, in this case, uh prove uh to indiegogo that um that indigala can show games such as the sexy lady to the left side and and third, I should be able to tokenize my membership.

A

So if I have, for example, humble bundle, membership or then games that would be discounted because of that membership should jump out, these would give um indie gala.

A

This gives us what we wanted in the for decentralized web in the first place, which is allowing innovation, which is um allowed users to share their own information in their own confidential manner and allow computation- and this brings us um the need for new technology which does not authenticate users by their id, but by what they have like the product tokens and membership tokens I just mentioned.

A

So this would be token negotiation. um Token negotiation is a protocol that enables users to use tokens and websites in plain language. Now, it's not just where you have the ethereum address and website can look up what tokens you have by looking at ethereum blockchain. It includes negotiation component where the user is able to decide and the website is able to react to it, and here is the example.

A

Now before I introduce this example, um uh I need to mention that we worked with devcon for the next devcom project, where the ticket was tokenized uh with our technology, which do use the token negotiation that allows um devcon tickets to be used by other websites. So in this case it's a hotel website. It's a hotel and it's um um you can see here. There are the hotels offering three rooms. This is a concept and you can find the the code for this concept.

A

So first look at this um hotel has been offered and on the lower right corner, there is an ethereum icon. If you click that you can you, it shows what devcon tickets you have and if then you can see the website changes according to the tokens you have in this case the price is discounted.

A

Then, when you choose to book one of the hotels when you choose a token to be used on a website, there's no authentication. This is um something called adaptive authentication that we implemented in token negotiation.

A

That allows website to react to our tokens actually own. The token- and this uh allows the website to ask to ask you to verify the token ownership at the last stage when you are ready to book the hotel and pay for the hotel. So if then the authentication request is um popping up and then you need to authenticate by signing the message and confirm the quick booking.

A

So this is a three two minute overview of how token negotiation works, um but I wish to take this example and analyze. What are the features we need for such a process and the features which is trust, interoperability and privacy?

A

um First trust the technology need to ensure that tokens being displayed on the web being used on the web is what you really have so, and the website really reacts to the fact that you really own a a devcon ticket token, and not fooling you by saying that you have a token or accept a non-token probability issue where token issuers in this case has to participate in web service to a certain extent, and uh because this is this is step content that can take it being used.

A

The issue here, we will have, will influence the process a little bit, for example, by displaying the ticket in the way that devcon prefers.

A

And third, we have a privacy issue, so the website should only learn about tokens being used so taking in the example, hotel bagota trust element is um at work by having devcon ticket displayed rendered by a token script provided by devcon.

A

Devcon controls, revocation expiry and widely switches out other websites that can use the token without asking users for permission. First and third point privacy, where the website does not learn about users other unless user choose to expose them to the website and I'll quickly go over another uh go go over the the previous example of indigala.

A

If we use this.

A

Indigo trust indiegogo learns what games you have for your token and it will interrupt interoperability in the sense that user your game thumbnail, can be customized to your character and finally, privacy night, which came to have a you know that doesn't know your ethereum balance in a nutshell, this is what token negotiation does and it opens doors for few types of innovations such as identifier, token identification by giving attribute tokens proof of age and product tokens, for example, getting uh token related services.

A

And, finally, this is a quick link to the download code and run the demo. Thank you very much. I think it's 10 minutes exactly right.
