Web 3.0 may means decentralization powered by blockchain.

The internet is physically decentralized; no single entity owns it. But large, centralized services support its critical components such as server hosting, DNS services, email services, search engines, social media, cloud computing, and more. These services rely on resources concentrated in a limited number of physical or virtual servers. This approach makes it more convenient for companies to keep their services maintained.

But the same centralized architecture has created problems. If the servers of these entities go down, we lose access to vital functionality. If they get hacked, we lose our data. If they decide to monetize our data in unlawful ways or hand it over to government agencies, we likely won’t learn about it. If they decide to censor or prioritize content based on their interests, we won’t be able to do anything about it. In short, we’ve entrusted these entities with too much power, and they’ve become too big to fail.

During doing ODYSY, I red interesting article about blockchain and internet. It covers internet-decentralization ideas using blockchain and smart contract. It also introduces some brave startups try to realize them.

Most people generally have some idea that Web 2.0 is an interactive and social web facilitating collaboration between people. However Web 3.0 has the lack of a clear, distinct definition for it, and this is why the simple question of “What is Web 3.0” may get you dozens of different answers.

To summerize concepts used to predict and depict the Wed 3.0, There were semantic web, artificial intelligence and virtual reality. There have been a cynical view point that it’s merely a marketing term. By the way, Web 3.0 may means full decentralization powered by blockchain and smart contract.

A fully decentralized internet will have its own challenges, but its key promise will be to provide robust services that can’t be compromised or owned by any single entity, a distributed network gives users full control of their digital life and ensures privacy and equal access. If such an internet is destined to arrive, blockchain will surely be one of its principal building blocks.
