Blockchain

Blockchain :

Blockchain has grown rapidly throughout the entire world though its realization with Web 4.0, coupled with Internet-of-Things and Artificial Intelligence can bring the most necessary thing, which the Internet currently lacks: Trust. And that "Trust" can be enforced by a decentralized network.

There have been many attempts to create digital money in the past, but they have always failed.

The prevailing issue is trust. If someone creates a new currency called the X dollar, how can we trust that they won't give themselves a million X dollars, or steal your X dollars for themselves?

Bitcoin was designed to solve this problem by using a specific type of database called a blockchain. Most normal databases, such as an SQL database, have someone in charge who can change the entries (e.g. giving themselves a million X dollars). Blockchain is different because nobody is in charge; it’s run by the people who use it. What’s more, bitcoins can’t be faked, hacked or double spent – so people that own this money can trust that it has some value.
