Decentralized marketplace vs Centralized marketplace

Decentralized Autonomous Organizations - What is a DAO?

Written By Ivan on Tech

Aug 28, 2020

DAOs or Decentralized Autonomous Organizations happen to be one of the most innovative blockchain-based concepts. DAO is also known as DAC or decentralized autonomous corporation. The core philosophy is to create an organization that’s free from centralized control. 

As the name suggests, DAOs have three core features:

  • Decentralization: Not governed by one single, centralized entity.
  • Autonomous: The DAO can automatically execute operations on its own without any intervention.
  • Organization: The DAO is governed by its own predetermined rules, like an organization.

Since 2019, the support for DAOs has been increasing rapidly due to attention from the non-crypto world. An excellent example of this is the UK-based Nexus Mutual, which is the first decentralized mutual insurance incorporated as a cooperative and driven by a DAO. As such, decentralized autonomous organizations have made a pretty outstanding comeback since the disaster of 2016. However, we get into all that,...

Decentralized Finance in 2020 - DeFi Trends to Keep An Eye On

Written By Ivan on Tech

Aug 25, 2020

Despite its recent upswing in popularity, blockchain is still a relatively new technology that can be hard for some people to grasp. Bitcoin is probably the reason why most people know what blockchain is. However, Bitcoin as a currency relies on its vibrant community and underlying blockchain capabilities to keep growing and attracting users. 

Ethereum, on the other hand, is the reason why DeFi is growing at a tremendous rate. Ethereum’s support for smart contracts and the ability to tokenize it makes Ethereum perfect for a financial revolution, and is the reason why Decentralized Finance (DeFi) is hotter in 2020 than ever before. Let’s, therefore, take a look at decentralized finance in 2020 and what it means for the future of blockchain and finance!

How Decentralized Finance Works

Central authorities still largely dominate the traditional financial system. The role of these central authorities is to regulate the system, and act as middlemen between various...

Definition and Use Cases of Non-Fungible Tokens (NFT)

Written By Ivan on Tech

Aug 24, 2020

There appears to be an ever-increasing amount of information to learn about the various blockchain ecosystems. One of the terms that has recently seen an upswing in interest surrounding NFTs. NFTs (Non-Fungible Tokens) are becoming more established as the crypto sector heats up in what many hope will constitute a 2020 - 2021 bull run. So, what are NFTs?

In properly answering that question, however, we need to take a closer look at what non-fungible tokens, or NFTs, offer. Specifically, NFTs are bringing valuable assets to the blockchain through a wide array of industries including gaming, art, fashion, and real estate.

In this article, we’ll explore some of the key use cases for non-fungible tokens. We’ll also look at some of the latest token standards, how they are implemented, and what gives them value. First and foremost, however, we need to take a look at what blockchain technology actually is.

DeFi Deep Dive - What is dYdX?

Written By Ivan on Tech

Aug 23, 2020

Anyone keeping an eye on the DeFi sector will likely have come across the term “dYdX”. However, what is dYdX - and what is it used for? dYdX is a powerful, decentralized exchange (DEX) that supports spot, margin, and perpetuals trading. It is a permissionless platform powered by smart contracts on Ethereum that supports lending, borrowing, and most importantly, margin trading. 

In the true spirit of decentralized finance (DeFi), anyone can use dYdX without registering or handing over their assets to a central party. It is open, trustless, and non-custodial. Users can swap ETH, USDC, and DAI pairs as well as BTC and ETH on perpetual markets. We will touch on perpetual markets in a later article.

Trading Tools on the Blockchain

dYdX wants to bring trading tools from the traditional world of finance to the blockchain. Although it is decentralized, trading on dYdX is similar to trading on a centralized exchange (CEX). Options and margin trading are standard in...

Privacy Coins 2020 - What Are Privacy Coins?

Written By Ivan on Tech

Aug 22, 2020

For as long back as one can remember, the cryptocurrency community has been demanding for privacy coins. Coins that promised true anonymity, instead of pseudonymity, aka, false privacy as offered by Bitcoin. So, in this article, we are going to look up some of the top privacy coins in the world. Are the usual suspects still leading the privacy coins 2020 list, or do we have some surprising names in the mix? Let’s check it out. 

The need for privacy coins

There are two reasons why privacy coins are highly desirable:

  • Privacy
  • Fungibility

The need for privacy coins #1: Privacy

As mentioned before, the privacy afforded by “normal” coins such as Bitcoin and Ethereum isn’t absolute. To illustrate this point, consider the following example. We went to a blockchain scanner and picked up a random public address “bc1qq3fc75ppp5kq2qpe29wyl0708hzxxu34xk5836.”

Now, when you click on the address, you get this:
