What is Uniswap - Exploring Uniswap and the UNI Token

Written By Ivan on Tech

Oct 17, 2020

Uniswap is arguably the most popular decentralized exchange (DEX) on the Ethereum network, boasting over $2.7 billion in total value locked (TVL) at the time of this writing. To be more specific, Uniswap is an automated market maker (AMM). It allows anyone to swap ERC-20 tokens without having to find a buyer or seller on the other side of the trade.

Through being a DEX, people can use Uniswap in a trustless manner. They don’t have to deposit their funds or KYC identity documents to a central server where they can be hacked. After all, hackers do break into centralized exchanges (CEXs) quite often. So, to its credit, Uniswap has never had a hack or major bug inflict damage to its protocol. This has led to ever-increasing trust and has helped Uniswap vault to the top of the DeFi Pulse rankings.

The decentralized finance (DeFi) sector is hotter than ever, and Ivan on Tech Academy is your guide to all things blockchain-related, such as DeFi. What’s more, Ivan on Tech Academy...

Written By Ivan on Tech

Oct 14, 2020

Those keeping tabs on the crypto market will likely have heard the term “Ethereum 2.0” (or Eth2) being thrown around. As the name suggests, Ethereum 2.0 is an overhaul of the existing Ethereum network, intended to boost scalability and security on the network. A critical part of the path towards Ethereum 2.0 is the “Zinken testnet”, which went live on October 12th, at 12 PM UTC. However, what is the Zinken testnet exactly?

To put it simply, Zinken is an Ethereum 2.0 testnet intended to practice a mainnet launch. It can be seen as a “dry run” for an Ethereum 2.0 mainnet and is essential to complete before Ethereum 2.0 goes live and starts supporting substantial economic value.

Although the existing Ethereum network has served a real value, it is becoming increasingly apparent that Ethereum needs improvements to support higher volumes of users. This is becoming more pronounced than ever, as Ethereum adoption keeps increasing.

What is Decentraland - Explaining Decentraland, LAND and MANA

Written By Ivan on Tech

Oct 09, 2020

Decentraland is a decentralized, virtual reality (VR) platform where users can both create and monetize their content and applications. The digital land on their platform is simply called “LAND.” Specifically, it is a non-fungible digital asset maintained by Ethereum smart contracts. Decentraland split up their digital land into parcels so that users can purchase it using the MANA token.

We’ll describe all this in-depth, but for now, just understand that there is a finite amount of LAND available. So, the number one asset on Decentraland is scarce which is similar to Bitcoin. 

The cool thing is users who buy LAND own it outright and permanently. They can control how their LAND looks by choosing the scenes they want, what content they’ll display, and which interactive apps they’ll use. In short, the owners are in charge. Let’s therefore dive deeper and find out all about Decentraland!
