Blockchain Made Simple

Summary

Blockchain technology is a decentralized and distributed database system that ensures data integrity and trust through network consensus, enabling a wide range of applications from cryptocurrencies to decentralized autonomous organizations (DAOs).

Abstract

Blockchain simplifies the concept of a database by distributing copies across multiple computers, ensuring that any changes are verified and accepted by the entire network. This creates a universal, trustworthy database that is not controlled by a single entity. The distributed nature of blockchain allows for the development of applications that are universally accessible and transparent, promoting a new kind of internet where control is in the hands of the users rather than centralized corporations. The technology has a broad spectrum of uses, including cryptocurrencies like Bitcoin, platforms for decentralized applications like Ethereum, and the emergence of DAOs.

A lot of people think Blockchain is complicated, but the concept is actually extremely simple:

You make a copy of a database on everyone’s computers.

So instead of one single company like Google having and controlling a database, blockchain copies the database to everyone’s computers.

Any change to the database is copied by everyone’s computer on the network as well. Which makes the database universal and trustworthy. No change can be made to the data on the database without that change being accepted and confirmed by the network.

That’s it.

A distributed database that is run by the people. That is available and accessible everywhere and can be trusted.

Since databases constitute the basis of how we use the Internet out of a need to store our data and they are behind every single service that we use, this enables us to build applications that use this distributed database. This means that these applications can be available anywhere universally.

Anyone can get on the network and use the database, and anyone can run applications on it.

This creates some kind of ‘distributed’ Internet in which no central authority or corporation is in control, acting as a gatekeeper.

Moreover, this enables us to make transparent, verifiable interactions with each other since the entire network keeps a track of those interactions through the shared, universal database.

The applications are endless. From distributed crypto-money like Bitcoin to blockchain that can act as an infrastructure to build distributed applications like Ethereum, from DAOs to distributed blogs or content.

So, Blockchain acts as an agent that takes back the control from centralized entities like corporations and gives it back to the people.

A much-needed change.
