Understanding the ETH Hype and the Ethereum Bull Run 2021

Written By Ivan on Tech

Jan 10, 2021

The recent Ethereum bull run has caused quite a stir in the crypto space. Although the continuation of the 2020 Bitcoin bull run is still in full swing, eyes are turning to Ethereum as it approaches its previous all-time high. Some Ethereum predictions even suggest that we could see an Ethereum bull run in 2021 perform in a similar way to Bitcoin's atmospheric rise during late 2017. Many believe that it is only a matter of time before Ethereum embarks on a similarly explosive bull run. Moreover, as the roll-out of Ethereum 2.0 progresses, Ethereum’s infrastructure fundamentals are improving substantially.

In this article, we’re going to look at what is driving the recent price action of Ethereum. Also, we’re going to discuss the future of the Ethereum network, as well as go through some common Ethereum predictions for 2021.

Are you just coming across Ethereum for the first time and would like to gain a better understanding of how the Ethereum blockchain works? The...

What Is Tornado Cash and TORN?

Written By Ivan on Tech

Jan 08, 2021

Tornado Cash is a decentralized protocol designed for those looking to transact privately on the Ethereum blockchain. This protocol helps solve the privacy problem on Ethereum because whenever you buy or sell on that blockchain, your transactions are public. It's not like the blockchain will publicly post your name, but your address will be. For that reason, Ethereum is considered pseudonymous. However, if an observer can connect you to a wallet address, they can track you with research tools like Etherscan.

That means they could track things like the source of your funds, your balances, and your payments. In short, they could analyze your on-chain activity, including your entire transaction history. That's because transparency is the default position of Ethereum. 

So, this is why Tornado Cash has introduced private transactions. They exist to serve those who want anonymity and complete privacy. Therefore, if you're one of those people who doesn't like others snooping on your...

Talking About ETH Gas - Ethereum Gas Explained

Written By Ivan on Tech

Dec 19, 2020

If you’ve just entered the world of decentralized finance, you may be asking yourself: “What is Ethereum gas?” or “What is Gwei?”. Well, you’re not alone! Rarely is Ethereum gas explained to new users or understood properly. Gas is the fee paid to Ethereum nodes to mine transactions. Therefore, Ether gas price is the cost of an Ethereum transaction fee. This applies to any token transacted on the Ethereum network. The Ether gas price can fluctuate dramatically depending on network congestion. This is something that many newcomers fail to understand, and as a result, get "rekt" as a result.

In this article, we’re going to explain what happens when someone pays an Ethereum transaction fee. Also, we’ll explore the dynamics of Gwei and Ether gas price and the function it plays in the Ethereum ecosystem. 

Ethereum is the second-largest cryptocurrency following Bitcoin. Also, Ethereum is the backbone for decentralized finance, with over...

Written By Ivan on Tech

Dec 09, 2020

Smart contracts are some of the most fascinating and important inventions at blockchain developers disposal. Essentially, smart contracts allows programmers to develop self-executing code that can be used in several fields such as decentralized finance (DeFi). This technology has the potential to save a huge amount of money for businesses and organizations all over the globe. As this technology has vast potential, several smart contract platforms compete in order to offer developers the best tools.

Many different platforms allow developers to utilize smart contracts. However, in this article, we are going to take a closer look at four main smart contract platforms. 

Some of the largest smart contract platforms out there are EOS, Ethereum, RSK and Cardano. Seeing as such, we will take a look at the smart contract platform struggle of EOS vs Ethereum vs RSK vs Cardano. However, before discussing the differences and benefits of each platform, it is important that you have a...

Ethereum Code: Examining Ethereum Programming and Ethereum Smart Contracts

Written By Ivan on Tech

Jul 06, 2020

Ethereum is one of the most fascinating and impactful projects in the crypto space. By bringing in the idea of programmable blockchains, Ethereum pretty much ushered in the era of smart contract platforms. Now with Ethereum 2.0 just around the corner, let’s familiarize ourselves with Ethereum code. 

Ethereum Code: The Ins and Outs of Ethereum smart contracts

What code is Ethereum written in? How to code Ethereum smart contracts? What are ERC-20 tokens? Let's answer all these questions in this guide.

What code is Ethereum written in?

Vitalik Buterin, a Russian-Canadian programming prodigy, first released the Ethereum whitepaper in 2013, describing it as a platform that can accommodate decentralized applications (Apps). Ethereum has a long list of co-founders and was coded using– Go, Rust, C#, C++, Java, and Python.

However, when learning about Ethereum code, this is not the main information that most developers are looking for. The truly fascinating aspect of...

Smart Contracts Explained - What Are Smart Contracts?

Written By Ivan on Tech

Jul 01, 2020

Smart contracts have pretty much become an integral part of the “blockchain offering” alongside cryptocurrencies. However, we are at a weird conjuncture wherein we are either overestimating or underestimating the real capabilities of smart contracts. In this article, let’s gain a clear perspective of what they are and how they can revolutionize different industries and sectors as we move towards the future. So, how do smart contracts work? Let’s begin with the basics. 

What are smart contracts? 

How do you define contracts in the legal world?

Traditional contracts are human-readable, agreements between two parties. The agreements stated in the contract are a set of agreed-upon terms. Usually, one party needs to fulfill some tasks for the other party in exchange for a payment. A lawyer oversees this entire contract. 

As you can imagine, this third-party acts as an obvious point-of-failure in the entire agreement. The only way that either of the...

Breaking Down ETH 2.0 - Ethereum Layer-2 and Scalability Explained

Written By Ivan on Tech

Jun 22, 2020

As you are probably aware, we are on the verge of an Ethereum revolution, colloquially known as ETH 2.0. This upgrade is going to bring in a lot of innovations to the popular Ethereum protocol.

We have covered two of the most significant changes - Casper and Sharding - in detail before. In this guide, let's cover another exciting innovation that is going to give the overall scalability a significant boost - Ethereum layer-2 scaling.

Ethereum layer-2: Solving the scalability problem

Numerous sources have very extensively documented Ethereum's scalability problems. Decentralized cryptocurrencies are inherently non-scalable due to their design issues. Ethereum does around 25 transactions per second, which is pretty abysmal but still marginally better than Bitcoin, which can only do seven transactions per second. 

This low transaction throughput happens because of the amount of time it takes to validate and put in a transaction within the block. 

Design problems of...
