What is the character of Polkadot?

The biggest character of Polkadot is "Interoperability".

It means connecting different blockchains to make them interoperable.

What means?

Previous blockchains, such as Bitcoin and Ethereum, were not compatible and could not be connected to each other.

So, when trying to convert Bitcoin to Ethereum, it had to be traded on an exchange.

Going through an exchange means you need something centralized with an administrator.

In other words, blockchains were decentralized but people need something centralized for exchanging.

However, through Polkadot, it is possible to connect different blockchains and create a completely decentralized web world = Web 3.0.

This is what I'm excited about Polkadot!
