NFT Based Content Restriction in ASP.NET - What is Web3 login?

What is Web3 Login?

Web3 login refers to using your digital cryptocurrency wallet as credentials to sign into a particular website, service, or application. Rather than using a traditional username and password combination, a public and private key pair authenticates you and grants you access.

This mode of authentication is exponentially more secure than Web 2.0 login, even with all its peripheral security features and extensions. Web 3.0 refers to blockchain technology, which is self-attesting and practically impossible to break. Given that thousands or even hundreds of thousands of blocks in a chain keep each other error and tamper-free allows you to put a high level of trust in its reliability.

Once you’re authenticated with a Web3 login, you can use features like tokengating to restrict or provide access to certain services. Holders of different cryptocurrencies and NFTs can be targeted for specific markets, thereby enhancing their experience.

What is NFT Gating?

NFTs, or Non-Fungible Tokens, are cryptographically encrypted tokens that are unique in nature. Meaning, they are non-fungible. These tokens can be used to represent digital or even physical assets of a large variety. Thus, the sale and purchase of these assets can be carried out simply by exchanging these NFTs for either a traditional currency or another NFT.

Using the concept of Web3 login we mentioned above, a user can log into a website or application with their crypto wallet and use the NFTs owned by that wallet as an entry to certain services and features. In other words, NFT gating is the process of restricting access to a website, application, or specific sections of the same behind the ownership of NFTs. NFT gating becomes another way of ensuring whether a user has made a legitimate purchase and deserves access to a service behind a paywall. Exclusive memberships and VIP events can also be gated behind special NFTs that are available to a select few people.

Tokengating allows you to create NFT gated communities where like-minded individuals can share NFT gated content with each other. It may not even be a tangible asset, but an experience that can be shared and collaborated on. This is just one of the use cases made possible by the NFT API.

Built on a Peer-to-peer (P2P) protocol, Web3’s Single Sign-On does not suffer from downtime and malfunctions of a traditional Web2.0 system that relies completely on the service provider’s server health.

NFT Based Content Restriction in ASP.NET - No Censorship
No censorship

Free from censorship and central administrative power

The decentralized nature of the protocol prevents any single user from censoring, shadow-banning or locking you out of the service, unlike centralized systems that concentrate the administrative power into the hands of a few select users.

What are the Benefits of Web3.0?

A fundamental aspect of Web 3.0 is its decentralized nature thanks to blockchain technology. It eliminates the centralization of control and authority, while also increasing the security of data. It is scalable, making it future-proof for large-scale applications, and accessible, allowing people who are not tech-savvy to take advantage of its many features. Web 3.0 takes power from a handful of large, monopolistic tech giants and puts it in the hands of all the people using its technology equally. It fosters freedom of expression, protecting an individual’s right to privacy and ownership of their data.

What are Decentralized Applications (dApps)?

Decentralized Applications (dApps) run on a peer-to-peer (P2P) network based on a blockchain rather than a centralized server. They are a lot less restrictive than traditional, centralized apps that are under the control of a single authority. Ethereum is the most popular decentralized, open-source blockchain that can be used as a platform for dApps. This also means that making transactions on dApps is efficient because there is no one to take a cut. And since they’re using cryptographic blockchains as a platform, they are secure and protect your privacy.

NFT based login and Content Restriction

Ownership of NFTs can be a requirement for users to log in or browse content on your ASP.NET application like pages, posts, images, videos, documents, or other customized content. Conversely, you may also make it such that ownership of certain NFTs blocks or prevents access to certain content. This is supported by various blockchain networks like Ethereum, Ethereum Classic, Polygon (Matic), Optimism, BOBA Network, Gnosis Chain (xDai), Fantom Opera and many more

What are Smart Contracts?

Smart Contracts are small programs stored on a blockchain that automatically execute when a particular condition is met. They are essentially a type of Ethereum account, but one that a user cannot directly control. User accounts can interact with a smart contract by submitting transactions that execute a function defined by it. Our solution enables you to create smart contracts easily and store the record on the blockchain.

Implementing NFT Gating in ASP.NET

ASP.NET is a web application framework that can be used to create websites and web applications. It is incredibly dynamic, stable, and flexible. As such, implementing NFT gating in ASP.NET applications should be a piece of cake

First, you need to figure out for what purpose you’re making the application. The potential is quite vast as there are several different industries that can make use of an ASP.NET application. Examples range from healthcare, banking, education, sports, and eCommerce to online ticket sales, entertainment, and media.

You have several options in creating an ASP.NET application, be it Web Forms, the MVC framework, or a classic ASP/PHP web page. Restricting content behind the ownership of NFTs can be implemented in a variety of ways and isn’t limited to just subscription models.

How will the Wallet Login Flow work?

Generating the Nonces

For each user, a Random string in the nonce field is generated, this can be a random number.

Nonce is fetched by the user

Aftern clicking the login button, an API call to the back end is sent to retrieve the nonce associated with the users public address

User Signs the nonce

User will be shown a pop-up to confirm the nonce and will be able to accept it hence signing the nonce

Signature Verification

With the authentication verified, cryptographically it will be verified that the nonce has been correctly signed by the user and the public address belongs to the same user
