Respondent: zhongnan zhang, co-founder and CEO of AlphaWallet
This year's European championship will be more than twenty thousand tickets to the NFT (Non - Fungible Token) form. Given the impact of the event itself, we can argue that blockchain has finally brought NFT tickets to the ticketing market after the Internet brought electronic tickets.
The 20,000 tickets issued on the blockchain are being launched by Shankai, uefa's sole sales agent in Asia, in partnership with AlphaWallet, the cryptocurrency wallet, which is providing the tickets and funding the development. AlphaWallet will provide the technology. These token tickets can be used through tokenscript-compliant ethereum wallets, such as AlphaWallet, and a customised ethereum wallet will be launched by blooming sports to provide a better user experience.
This will be an important moment for blockchain technology to reach ordinary consumers and realize large-scale application. Nearly 940 million people worldwide used digital tickets in 2019, according to data provided by AlphaWallet CEO zhongnan zhang. If 5 percent of that could be converted into blockchain-based token tickets, he believes, it would already be more than all current global blockchain users.
According to the developers, NFT tickets for euro 2020 will be sent to buyers once the contract is developed in February and released on ethereum's main network. By then, the 20,000 etheree-based NFT tickets will enter the electronic wallets of ordinary consumers and be freely transferable, bringing blockchain applications into the daily lives of ordinary people.
An NFT ticket is essentially a non-homogeneous token generated on the blockchain network. This NFT ticket for euro 2016 is issued on ethereum using the improved version of ERC721 standard and TokenScript standard description language.
Thanks to these improvements, these blockchain-based NFT tickets are portable, scalable and interoperable, helping to create frictionless markets, according to zhang. At the same time, the ability of these NFT tickets to atomise payments (DvP, Delivery Versus Payment) without the need for a centralised, trusted third party to guarantee transactions also helps to create frictionless markets.
In other words, the market is more open, and anyone, anywhere in the world, can participate. It's also more efficient. You pay for it, you deliver it, and once the deal is done, the seller gets 100% of the money, and the buyer gets 100% of the goods.
In addition, local files implemented using the TokenScript standard description language can help token get rid of the limitations of existing tokens and become a service integration point with value, benefits and functions. (for the specific concept of TokenScript, please refer to the article "re-understanding token, understanding the new TokenScript".)
In other words, all services can be integrated on the client side through NFT tickets, such as ticket services, insurance services, car booking services, souvenir sales and so on, while users can also choose any services based on tickets freely and conveniently.
As 20,000 euro 2008 tickets go on sale in NFT format, we spoke with AlphaWallet co-founder and CEO zhongnan zhang to help us understand what's different, what's good, and how to make these big breakthroughs.
Advantage of NFT tickets: frictionless trading market
Q: electronic tickets are already convenient. Why use NFT tickets?
Zhang zhongnan: when tickets are in circulation and integrated by different third-party systems, NFT tickets do not require the original issuing institution to participate in the verification, which brings two major benefits. The second is the opening up of the integration market, which greatly reduces the difficulty of integration and makes it easier for users to use the services and service providers to provide services.
Q: how can NFT tickets be verified without the participation of the original issuer?
Mr. Zhang: when a user views a ticket in a wallet or web page that supports the TokenScript standard, he will find a signature message in the upper right corner of the ticket, which is the signature of the publisher. NFT itself (smart contracts plus TokenScript) carries all the verifiable information, so there is no need to go back to a centralized server, either in circulation or during integration.
This integrity of NFT tickets makes them portable, scalable and interoperable, features that help create frictionless markets; NFT's ability to atomise payments (DvP, Delivery Versus Payment) and avoid the need for a centralised, trusted third party to guarantee transactions also helps create frictionless markets.
This market is more open, and anyone, anywhere in the world, can participate. It's also more efficient. You pay for it, you deliver it, and once the deal is done, the seller gets 100% of the money, and the buyer gets 100% of the goods.
Q: how does the frictionless market work?
Mr. Zhang: the simplest thing is that the NFT ticket contract has a built-in transaction function. Any ticket owner who selects the ticket in his wallet will see the function of selling and transferring tickets directly. When tickets are sold, a MagicLink is generated, which is a message containing the signatures of the parties, as well as the ticket price set by the seller, in the form of a link or string.
The seller can take this MagicLink release the information to any social platform or platform, want to buy the tickets for the people only need to copy this article MagicLink information and opened his wallet, purse will automatically suggest he need to pay the amount, if he agreed to pay, signing messages will be broadcast to Ethernet network, the seller received the fare, and he became a tickets for the new owner.
The biggest concern for buyers is buying fake tickets, but NFT cannot fake them. Counterfeiters may be able to make two identical paper or electronic tickets, but there is no way to make two identical NFT tickets.
Companies or organizations, such as hotels, football forums, etc., can also easily create a ticket market within their own systems to offer ticket services in the form of MagicLink. In fact, TokenScript can be used to display tickets as ticket information and ticket status, which is a more friendly way to create a trading market. However, the NFT tickets for the euro tournament hide this feature.
Q: can tickets be bought and sold on NFT markets such as OpenSea, the largest NFT exchange?
Zhang zhongnan: NFT tickets for the euro 2016 are based on the improved ERC721 standard, which is compatible with existing infrastructure and can be traded on OpenSea. As long as the user has a DApp browser wallet, they can see the ticket on OpenSea and set the transaction options to sell or buy the ticket.
It should be noted that OpenSea does not support TokenScript at present, so it can only show the part described by NFT ticket with smart contract, but not the part described by NFT with TokenScript. At this time, the purchaser cannot identify the issuer's signature for fidelity, so he needs to check whether the address of the smart contract issuer of NFT is correct to judge whether the ticket is real or not.
There is no technical difficulty in getting a platform like OpenSea to support TokenScript. Next, we'll work with platforms like OpenSea to push them to support this feature. This is good for these platforms.
Q: what benefits can NFT tickets bring to issuers or equity holders?
Mr. Zhang: a more open and efficient market benefits both the buyer and the issuer. In addition, the issuer can define the rules for the circulation of NFT tickets in the smart contract, so that each participant can automatically participate in the market according to the rules. For example, set the turnover times (some VIP tickets do not want to be resold), limit resale price, participate in resale profit sharing, etc.
Advantages of NFT tickets: open integrated market
Q: after introducing the trading market, what is an open integration market?
Zhang zhongan: to give you an example of a real integration problem for the European championship, Booking.com is the official accommodation partner of uefa. They have targeted a large number of hotels for the European championship, but according to uefa's requirements, these hotels can only be provided to holders of tickets for the European championship. Booking.com can't verify who has the tickets under the existing technology, so they have to push the hotel inventory to the ticket agent and ask the agent to help them sell the tickets, but the ticket agent doesn't know who has the tickets after the ticket is sold, so they can only sell the tickets.
There is a central solution to this problem, but it requires all participants, including every user, to access a closed system managed by uefa. This is not realistic, the parties will not integrate into the system, and even if they do, it will create a lot of friction.
The reasons for the failure of integration can be referred to the article "solving the integration needs is the key to the future block chain business" :
https://www.chainnews.com/articles/847407790351.htm
But NFT can solve the integration problem. NFT tickets themselves provide complete, verifiable information, so the service provider does not need to connect to the ticketing system to authenticate the user's ticket and identity. All they need to do is add a piece of code to their system to validate the NFT ticket, which then shows the user the page and provides the service. Think of a blockchain as an open database, with a simple verification action on the part of the service provider.
For ticket holders, they only need to log in the website of the service provider through the ticket and start using various services after the verification of the service provider. In other words, users no longer need to repeatedly register, input various information and wait for verification when logging into different websites. An NFT ticket can save them all the steps, which is very convenient.
Q: if you take hotel services as an example, what is the implementation process of integration?
Zhang zhongnan: the hotel website adds code to enable its own system to verify NFT tickets. When the user accesses the hotel website through the browser in the wallet, the browser will prompt the user to log in with NFT tickets. Is the browser rather than site tooltips, because it involves the security trust problem such as anchor, interested can through the video to understand: https://youtu.be/Yl7x8DRth9E.
The user confirms "login", the website after verifying that the user has the correct NFT, will show the exclusive booking page of the hotel to the ticket holder, and can recommend the appropriate hotel products for the user according to the information in the NFT ticket, such as game time, location, game times and so on.
Q: what are the other features of the integration marketplace through NFT, or token?
Mr. Zhang: this service integration is infinite, applicable to and accepts (without access) any supporting services related to token. For example, the airline ticket service, insurance service, car booking service, souvenir sales and so on, Uber can provide special discounts for ticket holders to attract these users if it is willing. I think there will be a large number of service providers willing to use NFT ticket /token as the integration point to provide services to users.
All services can be integrated on the user side through token, and each token is equivalent to a fully open API on the user side, which means that all the APIs of alipay, WeChat, facebook and other platforms are in the hands of users. This analogy is not particularly rigorous, but it is convenient for us to understand the power of user side integration.
Specifically, on the Internet, we take big platforms such as alipay and WeChat as integration points, and call different systems through these platforms. However, alipay can only use services integrated by alipay, while WeChat can only use services integrated by WeChat.
As the integration point, token is to return to the user the information that is verified by alipay or WeChat to provide the third party to use, so that block chain can provide authentication instead of these large platforms. The integration of services happens on the user side, not on the platform, and there is no such thing as an Internet platform. Everyone's wallet is an integration platform that can integrate an unlimited number of services. Any service can be provided to the user based on token, and the user is free to choose any service based on token.
NFT ticket technology
Q: what are the four concepts of NFT, ERC721, TokenScript and smart contract?
Mr. Zhang zhongnan: NFT is a general term for a class of tokens, which are implemented through smart contracts on the block chain and TokenScript (or other off-chain components). ERC721 is a standard for implementing NFT smart contracts on ethereum. There are countless smart contracts to implement NFT. If there is a standard, interoperability between contracts can be easily realized.
TokenScript is a standardized description language for token. Through TokenScript, a TokenScript local file can be generated. Together with the smart contract, a complete token can be realized. We can understand it as simple as this: for a token, part of its information is put in the smart contract, and part of the information and logic are put in the TokenScript file, which contains the description information of token, use logic, UI rendering, program interface, interaction with the smart contract and so on.
Q: why do you need the other half of TokenScript when a smart contract can implement NFT?
Zhang zhongnan: smart contracts can only define part of the rules of NFT, but some other logic is missing. Advanced, some of the chain does not involve the transaction of the functional implementation, such as dynamic two-dimensional code display, location-based services, user notifications and so on; More advanced, when token is the integration point, it involves the definition of trust, privacy, security, interoperability and other aspects of the technical framework.
For example, this NFT ticket can directly complete the payment within the contract. The implementation of this function requires not only the support of smart contract for DvP protocol, but also the user terminal to know how to construct the corresponding transaction, which is provided by TokenScript.
As mentioned earlier, NFT tickets support various levels of signatures so that user terminals, such as wallets or websites, can recognize the issuer's signature, which is implemented through TokenScript; When users use MagicLink to import tickets purchased from the official website into their wallets, they also need to use TokenScript to realize the function that only real buyers can import tickets.
Q: if you put NFT tickets in a wallet that can't parse TokenScript, is it possible to put them there as a normal token instead of using the rich functionality implemented through TokenScript?
Zhang zhongnan: yes, it is a common 721 token. There is no ticket information display, no MagicLink function, and no issuer signature to ensure the authenticity.
Q: from a technical point of view, how is an NFT ticket structured?
Zhang zhongnan: NFT tickets themselves are smart contracts plus TokenScript local files. The technical stack at this stage of the tournament is as follows:
The first floor is ethereum. The second layer is an improved version of the ERC721 contract, the contract built-in DvP protocol, NFT ticket part of the information is here; The second layer also includes the xDai network, though this will be replaced by the Attestation (certificate) feature, which will use the ethereum main network directly in the future. The third layer is TokenScript, the other part of the NFT ticket information is here. The fourth layer is the user layer.
Euro NFT ticket guide
Q: how do I buy NFT tickets?
Zhang zhongnan: you can buy tickets with French currency on the official website. After the purchase, you will receive a MagicLink. With this signature information, you can import the tickets into your wallet. If the buyer does not make a secondary transaction, the ticket will be stored in his wallet as an "Attestation," a credential, and saved.
This process does not need to send the transaction chain, so the user does not need to have the password currency to pay gas, nor does he need to know any block chain knowledge. For him, this process is the same as buying ordinary electronic tickets, which will not bring additional cognitive burden.
Think of Attestation as an NFT whose ownership cannot be replaced. When the user needs to transfer the ticket, the smart contract on the chain will verify Attestation and convert Attestation into NFT and replace the ownership.
Q: do I need to exchange NFT tickets for paper tickets before admission? If not, how do ticket inspectors verify the authenticity of tickets?
Zhang zhongnan: the final plan has not been confirmed. Technically, tickets can be verified by scanning dynamic qr codes directly at the entrance. The ticket holder generates a qr code through the wallet. This qr code is dynamic and has a failure time. Every generation requires the user's signature, which cannot be copied or reused. The qr code contains the message of token ID and user signature, and staff scan the qr code to verify the user's signature, wallet address and token ID in the corresponding contract.
Q: can any event organizer easily distribute NFT tickets using TokenScript?
Mr. Zhang: basic development capability is required. It's like throwing HTML to people who don't know how to build a website. They can't build a website. However, if there is a "fool's platform" like Wix, which is actually what blooming sports and some of our other partners will do next, blooming sports will make a Wix of block chain tickets/coupons, so that other companies like them can issue NFT tickets very easily.
EDCON, which will be held in April this year, will also adopt the same ticket solution as euro 2016. During the conference, you can also get over 100 NFT with different functions. Welcome to join us.
Blockchain is one option
If you have a browser wallet, you know how comfortable it can be. Buy a couple of domain names at ENS, buy two cats from Cryptokitties, play a game, and then open Opensea to find the domain name, the cat, and the down game kit all there for you to auction off. If blockchain can be used for anything, that's what it's for. This use is not derived or advertised, it is used and selected.
That may be why the launch of NFT tickets for euro 2020 is a bit of a thrill, opening up a new opportunity for many people to use products that only blockchain can achieve. If it works, it can "replace" its internet-like counterpart.
Blockchain is not a day to complete the landing in 5 or 10 years, it is a long time to the traditional Internet penetration and nibbling, and to find a breakthrough one after another let everyone use blockchain, is to give the block chain again and again the opportunity to attack.
This summer, let's try NFT tickets.
