Security and Privacy in Web 3.0

Security and Privacy in Web 3.0


The online space has improved significantly in recent years, and with the Web 2.0 iteration, marketing possibilities became virtually infinite, especially because it employs multiple target market tactics.

In terms of capabilities, Web 2.0 is an excellent instrument for digital marketing since it provides multiple options to ensure that a product or service is advertised to the appropriate audience.

In a similar vein, Web 2.0 is also noted for its rash disregard for user privacy policies.

Web 3.0, which also serves as the most recent version of the internet, on the other hand, follows an altogether other sets of rules. The web 3.0 internet iteration is notable for being constructed on the blockchain, making it open, decentralized, and more secure than prior online iterations.

About Web 3.0

Even as Web 2.0 continues to engulf us, Web 3.0 is the latest incarnation of the internet. The decentralized internet, the spatial web, and the semantic web are all terms used to describe Web 3.0 which is set in context by a brief timeline of the Internet's evolution:

  • Web 1.0 consisted solely of static desktop web pages.
  • Web 2.0 is defined by interactive content on desktops, mobile devices, and social media, as well as persistent device connectivity.
  • Open-source software and trust-less (users connect openly or privately without the help of a trusted third party) and permission-less (no regulating body) networks will define Web 3.0. Edge computing, decentralized data networks, and artificial intelligence will be used to create it.

According to Deloitte, Web 3.0, also known as the spatial web, will combine machine learning from the semantic web with distributed ledger technologies such as blockchain to authenticate and decentralize information, allowing users to "interact with information away from screens and into physical space".

Decentralization and more user participation and control over data will undoubtedly be trademarks of Web 3.0. Rather than being stored exclusively in central data storage, data will be disseminated among a variety of computing resources, including phones, appliances, sensors, and vehicles.

Augmented and virtual reality, enhanced networking (e.g., 5G), geolocation, Internet of Things devices and sensors, distributed ledger technology (e.g., blockchain), artificial intelligence and machine learning, and distributed ledger technology are some of the enabling technologies for Web 3.0.

Web 3.0 innovation includes cryptocurrencies, but as Mersch and Muirhead write in The Medium, Web 3.0 "leads to a "return to the global village" — immersion in the human-centric and highly personalized interactions from which we used to benefit, but now delivered at the global scale of the internet and supporting an ever-increasing myriad of human and machine skill.

Web 3.0, according to the Forbes Technology Council, promotes "real sovereignty", in which people own and manage who profits from their time and information... "and overshadow an exploitative and unjust web, where the only ones who control and profit from it are huge, centralized repositories".

How does Web 3.0 improve privacy?

In terms of privacy, this brave new world means that humans, businesses, and machines will be able to share more data with significantly improved privacy and security. Users will own their data and digital footprint via decentralized identity technologies, and we will no longer rely on (or at least communicate on our own terms with) Big Tech platforms with all their inherent vulnerabilities.

In 2018, the IAPP outlined exactly what Web 3.0 could entail for privacy, and it was upbeat:

  • We'll utilize cryptographically secured digital identities to conduct transactions that presently require us to hand over highly sensitive and valuable personal information in an untrustworthy manner. We'll stop being the product and start being the client again.
  • Furthermore, governments will not be able to control our data. Instead, all programs, users, and linked devices will interact directly, with data kept in a safe, decentralized manner. This will result in fewer data breaches affecting huge groups of people, and individual users will regain control of their data.


Finally, Web 2.0 has accelerated the world's technological advancement. Web 3.0 is coming, and blockchain will most likely be the fundamental technology that drives this advancement at scale. Web 3.0 is coming as a natural progression of the internet and tackling issues around user privacy/data breaches. If you want to be an active part of the incoming Web 3.0 future, you will need some crypto, and if you haven't got a lot of money for investing you can read guide how to buy kava and start from this.
