Difference between http3 and Web3

What exactly is Web3?

Web 3.0 comes from the fusion of artificial intelligence, machine learning, and blockchain technology, allowing real-time communication between people. To top it off, web 3.0 not only provides consumers control over their data but also compensates them for their online time. The semantic web’s premise is that it understands and interprets the context and meaning of data. Consequently, when a user looks for an answer, web 3.0 provides the most accurate and relevant result. As a result, Google, Facebook, and Microsoft are among the few corporations profiting handsomely from user data. Users can also sell their data to advertising while maintaining control and privacy.

Web3 will also enable websites and applications to make greater use of data and tailor content to particular users. Web3 is still primarily theoretical, with a high learning curve. That’s a step that not everyone wants to take only to utilize a different version of what they already have, especially if they can circumvent privacy issues using programmes like private browsers.

Web 3.0’s Key Features

The following are the primary elements of web 3.0:

  • Because it was created with open-source software by a community of open-minded developers that is accessible to the general public, it is ‘open.’
  • Users have the flexibility to engage openly and privately without the danger of an intermediary, resulting in “trustless” data.
  • Anyone, including users and suppliers, can participate without a governing organization’s approval.
  • As part of Web 3.0, the Internet will become ubiquitous, enabling access to it from anywhere. In the future, internet-connected devices will not just be limited to computers and smartphones, as was the case in web 2.0. Instead, the Internet of Things (IoT) will enable a wide range of new intelligent devices.

What exactly is HTTP/3?

HTTP/3 is a significant update to the Hypertext Transport Protocol (HTTP), which underlies information transfer on the Internet.

HTTP/3 is implemented using QUIC, an encrypted general-purpose transport protocol that multiplexes multiple data streams over a single connection.

Google was the first to create QUIC. The protocol employs User Datagram Protocol space congestion management (UDP).

What are the advantages of using HTTP/3?

  • The transition to QUIC goes a long way toward eliminating one of HTTP/2’s most significant issues, notably “head of line blocking.”
  • Because TCP’s loss recovery methods are blind to the concurrent nature of HTTP/2’s multiplexing, a lost or reordered packet causes all ongoing transactions to cease, regardless of whether the missing package impacted specific marketing.
  • Lost packets only affect the streams where data has been dropped since QUIC uses native multiplexing.
  • The switch to HTTP/3 has the practical consequence of lowering the latency of slow or lossy internet connections.
  • Because QUIC is almost fully encrypted, HTTP/3 should considerably increase security.
  • According to Marx, the built-in encryption means that manipulator-in-the-middle (MitM) attacks are less likely, and QUIC also has additional safeguards to protect against denial-of-service vulnerabilities.
  • QUIC combines cryptography and transports handshakes to provide a single round trip connection to a new server. In addition, the client sends encrypted application data on its initial flight, allowing an interrupted connection to be swiftly resumed.
  • TLS 1.3 serves as the foundation for QUIC’s cryptographic handshake.

What are the hurdles that HTTP/3 deployment will face?

  • Software that supports QUIC and HTTP/3 is still in its early stages. “Strong cross-industry alliances are working effectively to address interoperability challenges as they occur, which gives us hope.” As the standard and various implementations develop, we plan to continue discovering and correcting bugs.”
  • Middleboxes that have historically been unfriendly to UDP traffic may be used by transit providers across networks (or even ISPs in rare situations).
  • To fully benefit from QUIC and let all clients use it, some networks with hostile middleboxes may require configuration adjustments.
  • It isn’t easy to enable QUIC for many server operators. For Cloudflare clients, for example, activating HTTP/3 is simple: start the HTTP/3 toggle on the dashboard, and everyone accessing their site with a supported browser will see it.
  • Client service is still not widely used. “We expect other major browser makers to follow Google Chrome in enabling HTTP/3 on QUIC for 95 per cent of their browsers now that the HTTP/3 with QUIC IETF standard has entered its final draught.”

What are the hurdles that Web3 will face?

  • Blockchain technology underpins Web3. Multiple blockchains are currently being developed to solve various issues. Some pitch themselves as speedy and cheap, while others have a unique selling concept of being decentralized. As a result, not many individuals can code. Furthermore, each blockchain has carved out its niche in terms of programming language, exacerbating the problem.
  • While Web 3 emphasizes keeping your assets in your wallet rather than entrusting them to a centralized platform, there is a minor issue. Purchases on one blockchain cannot yet be utilized on another owing to a lack of interoperability. As a result, owning your possessions is no longer enjoyable. Some Blockchains are attempting to tackle these issues with a feature known as ‘Bridge.’¬† These bridges, however, are frequently sluggish, costly, and unreliable. This renders them unavailable to the general public.
  • Scalability is a complex issue in Blockchain technology and a major roadblock to Web 3 adoption. The scalability trilemma states that only two elements of security, decentralization and scalability, may be chosen at any one moment.
  • Web 2 firms like Facebook and Google have put a lot of emphasis on these elements. As a result, they have some excellent items. These items are designed to make the user experience as seamless as possible. There are no obstacles or impediments to adoption. The point we’re trying to make is that the user experience comes considerably later in the development process. The current emphasis of Web 3 is to create functioning products that keep the decentralization ethos. Users’ interactions with them receive minimal attention.
