What technologies are used in Web3?

Web3 is a new frontier in decentralized applications. It is an umbrella term for various technologies used to build decentralized applications, including IPFS, Ethereum, and more. This article will discuss the technologies that make up Web3, how they work, and what they mean for application web3 developers and users. 


Ethereum is a platform that allows you to build decentralized applications, much like the internet itself. It’s also a blockchain and smart contract platform, which means it can build applications on top of its own technology. Ethereum has several different kinds of tokens, most notably:

  • Ether: This is the currency for users who want to be paid for their contributions or services in ETH; it’s also used as fuel for mining purposes on the network—more on this later!
  • Tokens: These are created when someone buys something using ETH but doesn’t have enough tokens yet; they’re then unlocked after being bought by another user who has them available.


IPFS is a peer-to-peer distributed file system, which means it’s not hosted on a single server and has no central authority. Instead, it uses the blockchain for data storage and authentication. 

This makes it very difficult for anyone to seize control of IPFS nodes or manipulate the network’s data without knowing how they work (i.e., through hacking). 

IPFS uses Git as its distribution format—think BitTorrent with a decentralized backend—and allows users to store files using git commits instead of storing them on some remote server somewhere else in cyberspace (like Dropbox). 

These objects are then made available using HTTP requests sent over UDP packets between peers who have linked their nodes via an encrypted handshake protocol called SOCKS5. 


Scuttlebutt is a decentralized social network that uses the same technology as Bitcoin. It’s similar to other peer-to-peer networks such as Napster, BitTorrent, and Gnutella. However, it differs from these in that its users can create their content on the platform and share it with others without going through an intermediary (like Facebook). 

This makes it different from other social media platforms like Facebook or Instagram because there is no centralized company controlling what you see on Scuttlebutt; this makes it more secure than most other types of social media sites out there today!


Dat is a peer-to-peer protocol that runs on top of IPFS, an open-source, peer-to-peer file system. It’s all about data sharing, making it easy for anyone to contribute their own data or files.

Dat was created by the Decentralized Web Foundation (DWeb), a non-profit organization based in Berlin that aims to build decentralized applications and protocols for Web3 development

The web’s goal is to make it easier for the web3 developer roadmap to build apps on top of its platform without having them rely on any centralized third-party service providers like Google or Facebook—or even just one company at all!

The goal here is simple: if you can remove those middlemen from your lives entirely, then you’ll be able to live more freely because there won’t be anyone holding you back from doing what you want with your own time and resources!


Textile is a decentralized social media platform that uses the blockchain to create a more secure and transparent user environment. The Textile protocol allows users to create their own social networks and share content with others without having to trust each other or third parties.

Textile aims to provide an alternative to Facebook, Twitter, and Instagram. It does this using its blockchain-based network, where users can interact directly with one another in real-time through chat rooms or groups (the same way you would on Facebook). This means that no one person can hold all of your data hostage—it’s all decentralized!


Web3 is an open-source platform that allows web3 developers to create decentralized applications by leveraging blockchain technology. Web3 companies build Web3 applications on top of existing products like Ethereum or Hyperledger Fabric and run in any browser, regardless of the operating system used.
