Cryptography, the science of writing codes and ciphers for secure communication, is one of the most important elements that goes into making modern cryptocurrencies and blockchains possible. The cryptographic techniques used today, however, are the result of an incredibly long history of development. Since ancient times, people have used cryptography to transmit information in a secure manner. Following is the fascinating history of cryptography that has led up to the advanced and sophisticated methods used for modern digital encryption.

The economy makes the world go round. It deeply affects each of us in our daily lives, so it’s certainly something worth understanding, even at a high level.

Banks often act as middlemen within the global economy by managing and coordinating the financial system through their internal ledgers. Since these ledgers aren’t available for the public to inspect, it forces trust in banks and their often outdated infrastructure.

Cryptocurrencies have brought lots of exciting possibilities, but they are also full of risks and dangers for the inexperienced. Follow the three main security principles outlined below to mitigate some risks associated with using, holding, and trading cryptocurrencies.

Game theory is fundamental to the development of cryptocurrencies and is one of the reasons why Bitcoin managed to thrive for over a decade, despite numerous attempts to disrupt the network.

In short, financial risk is the risk of losing money or valuable assets. In the context of financial markets, we may define risk as the amount of money one can lose when trading or investing. So, the risk is not the actual loss, but what can be eventually lost.

The Delegated Proof of Stake (DPoS) consensus algorithm is considered by many as a more efficient and democratic version of the preceding PoS mechanism. Both PoS and DPoS are used as an alternative to the Proof of Work consensus algorithm, since a PoW system requires, by design, lots of external resources. The Proof of Work algorithm makes use of a large amount of computational work in order to secure an immutable, decentralized and transparent distributed ledger. Contrarily, PoS and DPoS require fewer resources and are, by design, more sustainable and eco-friendly. To understand how Delegated Proof of Stake works, one must first grasp the basics of the Proof of Work and Proof of Stake algorithms that preceded it.
