Learning Blockchain Through Examples

Learning any technology is completed only when we are well familiar to its current use cases. By analyzing any use case we come to conclusion of how any technology can be used in real time. We all very well know about basics of blockchain and also should know about use cases.

Even though blockchain is very potential technology, we have to think about our expectation and cost of implementation. We have to think about is there really need of features of blockchain then only prefer this technology, this thing will be worthy.

Correlation between technology and its use cases makes easy to understand. As we know Bitcoin is very first use case of blockchain technology implemented in 2009. Since blockchain has reached at different heights over a time. We will see some examples of blockchain applications.

Polkadot

 Beyond a token transfer it is a true multi-chain application environment where things like cross-chain registries and cross-chain computation are possible.

Polkadot can transfer this data across public, open, permissionless blockchains as well as private, permissioned blockchains.

This makes it possible to build applications that get permissioned data from a private blockchain and use it on a public blockchain.

In simple words polkadot can connect any types of blockchain through XCM protocol.

For example, XCM could be used to communicate between a proof-of-work network like Bitcoin and a proof-of-stake network like Polkadot.

Some companies using blockchain
