Web3 - the decentralized web

In the early 1990's the WWW revolutionized information. Ten years later, the Internet became more
mature & programmable. We saw the rise of the so-called Web2, which brought us social media and
e-commerce platforms. It revolutionized social interactions, bringing producers and consumers of
information, goods and services brought closer together and allowed us to enjoy P2P interactions on a global
scale.
But always with a middleman, a platform acting as a trusted intermediary between A and B who did not
know or trust each other. While these platforms have done a fantastic job at creating a P2P economy with
an ever more sophisticated content discovery layer. They also dictate all rules of the transactions and
these platforms own all of our data.
In this context Blockchain seems to be a driving force of the next generation Internet, the Decentralized
Web, or Web3. Blockchain can bring us true P2P transactions without intermediaries and Bitcoin is the
first use case. While Bitcoin is P2P money without banks and bank managers, the same technology that
brought us Bitcoin could now allow us to build ridesharing without Uber, apartment sharing without
Airbnb and social media without Facebook and Twitter.

Killing​ ​the​ ​Server:​ ​Redesigning​ ​Data​ ​Structures-

We first had the computer and then we started connecting computers over the internet protocol. In the
early days of personal computers, we used to save data on a floppy disc, eject it, walk over to the
colleague that needed the file, insert the floppy disc into that person's computer, and copy the file onto
their computer so they could use it.
Data was centrally stored in one physical device. In order to transfer data copies needed to be made. The
internet made the transfer of these copies faster and massively reduced transaction costs.

30 years into mass adoption of the internet, our data architectures are mostly still client server based.
Which means that our data is centrally stored on one computer and retrieved via the Internet by another
computer over the Internet. Even though we live in an ever more connected world where every device
whether toaster or fridge are also connected to the Internet data is still centrally stored on our devices,
on the USB stick or even in the cloud.
​
This raises issues of trust. Can I trust those people and institutions that store my data against any form of
corruption, internal or external, man made or machine failure, on purpose or by accident? Such centralized
data structures have a unique point of failure.

From​ ​Data​ ​Monarchy​ ​to​ ​Data​ ​Democracy-

P2P data architectures have existed since the 1990's where they rose to fame with file sharing programs
like BitTorrent and Tor browser. In combination with cryptography and game theoretic incentive
mechanisms, Blockchain has taken P2P architectures to a new level. We can now start to move from
centralized data structures where all data is stored on a central computer to more decentralized or
entirely distributed data architectures.

In the Web3, we are redefining data structure, given that we live in a connected world. It is important to
note that Blockchain is only one of many technologies in this Decentralized Web Stack. While Blockchain is
a great P2P way to record who did what and when. It is not ideal for storing large amounts of data for two
reasons:
(1) scalability: blockchains are too slow and
(2) doesn't allow privacy by design:

Never store private data on the Blockchain.
​
Web3​ ​Technology​ ​Stack-

Similar to building a standard web or mobile applications, creating a dApp commonly requires a few
things: computation, file storage, external data, monetization and payments. The community has made a
lot of progress building the ecosystem in the past four years.
While it was borderline impossible to build a dApp in 2014. In 2017 it’s feasible to build a basic dApp that
requires minimal computation and file storage. The Web3 ecosystem has come a long way to develop a
technology stack that developers can build upon.

The transition from client-server internet to the decentralized web will be gradual rather than radical. As
the decentralized web stack is still maturing, the transition seems to be shifting from centralized to
partially decentralized to fully decentralized. Furthermore, it is important to point out that while
decentralized architectures are more fault tolerant and attack resistant, they are also slower.
While it is likely that the future of the internet will be more decentralized. This does not mean that we will
get rid of centralized systems altogether. Centralized systems also have advantages and will likely prevail,
but only for specific use cases.

So we will use centralized as well as decentralized applications based on our specific requirement and features.

Thanks a lot and waiting your comments.....
