What is Web 3.0 and how does it relate to the blockchain

Web 3.0 is a profound change in the underlying infrastructure of the network as we know it today. According to many, it will be a much deeper change than the one generated by Web 2.0 that has led the network from a passive source of information to be interactive.

So what is Web 3.0? There is no concrete definition of Web 3.0, but the latest developments in fields such as AI, IoT, advanced cryptography and decentralized systems give us some suggestions on what to expect.

Artificial Intelligence brings a capacity for understanding information to the systems we interact with. The first signs of this dynamic are already being seen today. In fact, if you ask your Google assistant who the President of the United States is and how tall he is, the software will know we’re talking about Trump. This trend is set to increase.

Another visible trend is the fusion of the virtual world with the physical one. The IoT (Internet of Things) consists of exactly this: common objects such as vacuum cleaners, light bulbs and toasters that are connected to the Internet.

For example: Are you coming home? The microwave is heating your lunch and the thermostat has turned on the heaters or the air conditioner.

Security in a connected world

All this comfort, however, brings with it many dangers.

A smart home is potentially much less secure than a normal home that can be opened with a classic key, and there are many criticisms of the low IT security standards typical of today’s IoT devices.

Blockchain technology is likely to play an important role in a secure authentication system without intermediaries, improving the security of these devices.

In fact, there are projects such as Slock that work to connect smart locks to the blockchain, in this case, that of Ethereum.

The decentralized web

It is difficult to expect that the decentralized infrastructure will only be used as a means of authentication or payment.

Projects such as IPFS seek to bring the decentralization and redundancy typical of blockchains to web hosting.

There are also decentralized DNS projects that should further contribute to the improvement of privacy for the next generation of online services.

While today every online website or service we use is offered through a server operated by a company that has access to all of its users’ data, this is likely to change in the future.

In fact, with infrastructures such as IPFS, data is saved with redundancy on numerous nodes and therefore censorship is rather difficult.

At the same time, privacy is also guaranteed by the fact that individual nodes contain data that is part of different websites, so to understand which website users view is not enough to know their IP.

The first services based on this decentralized infrastructure already exist.

A good example is dTube, the decentralized YouTube, but there is also the anonymous and decentralized eBay OpenBazaar.

The director of Coinbase himself recently stated that we are getting close to the decentralized web and many signs suggest that it will probably happen.
