The best tech buzzwords of 2021


The “Metaverse” generally refers to shared and immersive digital environments where people can meet, create, socialize, work, purchase goods and services, and attend events with others who are not in the area. same physical space. A true metaverse is supposed to mimic real life perfectly, although it’s unclear how many more years it will take to develop. The term metaverse was coined in the dystopian novel “Snow Crash” three decades ago. It was recognized this year after social media giant Facebook rebranded itself as Meta to reflect its new metaverse focus.

Web 3.0

Called the next version of the Internet, Web 3.0 will be built on the concept of decentralization, openness, and greater user utility. It will be based on blockchain record keeping technology, where users would have ownership shares in platforms and applications. In retrospect, the current version of World Wide Web or Web 2.0 is characterized by social media platforms, which allow a greater proliferation of user-generated content.

This is a far cry from Web 1.0, which was entirely static and non-interactive – an entirely top-down approach to information dissemination.

Block chain

Blockchain is essentially a database, but very different from any other database you’ve seen. As the name suggests, a blockchain is a chain of blocks, with each block storing information. The other key characteristics of blockchain are that it is decentralized, and by the very nature of this design, it is immutable. While cryptocurrency is the most popular use case for blockchain, governments around the world and in India are rushing to take advantage of this technology for governance and public administration purposes.


NFT is the abbreviation for non-fungible token. It is a unique digital certificate, saved in a blockchain that is used to register ownership of an asset such as a work of art or a collector’s item. Most people weren’t sure what an NFT was until this year, when sales exploded, largely sparked by former Twitter CEO Jack Dorsey selling an NFT of his first tweet for 2, $ 9 million. In India, the NFT craze came after Bollywood superstar and actor Amitabh Bachchan auctioned off his collection, including an autographed poster of his films, as NFT.
