Oracles in Web3 Explained

In ancient Greece, an oracle was a female priest who gave people advice from the gods. This priestess acted like a medium by revealing knowledge or answering questions. In the modern world, Oracles are essential services that act as bridges between blockchain networks and the external world. They are trusted intermediaries for the exchange of data by enabling smart contracts to access real-world data or connect to external IoT (Internet of Things) systems. Since blockchains are designed to be...

Web3 Grants Explained

We are currently in the midst of the Gitcoin GG22 Grant season, and it felt appropriate to tell you more about Web3-based grant systems. Similar to DeFi (Decentralized Finance), grants come with their native vocabulary, which is important to know in order for you to get involved. Generally, a grant is a financial award provided by an individual, organization, or government agency to a recipient, typically for a specific purpose, such as funding a project or research. Grants are a particular f...

Proof-of-Work vs Proof of Stake

As you know from our last article, blockchain technology relies on consensus mechanisms to validate transactions and maintain security. Two of the most prominent mechanisms are Proof-of-Work (PoW) and Proof-of-Stake (PoS). To simplify these concepts, we will be using another set of metaphors from the creative world. Ready? Let’s go!Proof-of-Work: The Artisan's CraftMetaphor: A Master Artisan Imagine a master artisan creating a unique piece of art. This artisan must source rare materials,...

Consensus Mechanism Explained

In our article “Blockchain Explained,” we used the metaphor of a fashion show to describe the participants and mode of operation of blockchains. The blockchain was visualized as the runway, where the models (aka blocks) are initially lined up, and as they walk down the runway, they will be added to the end of the line, thus building a chain of models/blocks. The audience members represent the nodes (computers) in the blockchain network. They watch the models walk and have a written copy of th...

Centralized vs. Decentralized Exchanges Explained

We are back with more; this time, let’s have a look at centralized vs. decentralized cryptocurrency exchanges, how each works, and how they are different. Imagine two bustling marketplaces in a city, each with its own unique character and offerings. One is a large, well-organized mall, with security guards at the entrance and a central management team overseeing everything. The other is an open-air market with a huge variety of stalls run by individual vendors, each responsible for their own ...

Liquid Restaking Explained

Remember one of our past posts when we explained what "staking" is and how it differs from "liquid staking"? Now, DeFi is evolving, and there is “liquid re-staking”! Are you ready for the next step👀? Once again, think about the metaphor of the decentralized art gallery: When you lend your painting to the gallery and earn a share of the ticket sales, but your painting is locked up in the gallery for a set period, that`s like staking in DeFi. If you receive a special "Art Token" for lending yo...

Blockchain Layers Explained

Last time, we discussed the different public blockchain networks available and the fact that there are other types of blockchains besides the public ones. This time, we will take a closer look at the different layers of Blockchain ecosystems such as Ethereum. The Ethereum Blockchain Ecosystem is pretty versatile, and one of the most developed ones out there, and it will make for a great example. To keep the information flow easy, we will avoid metaphors this time around as they introduce unne...

Blockchain Networks Explained

Last week, we talked about Blockchain as a general concept; this week, it is time to dig a bit deeper. As mentioned in "Blockchain Explained" (Article Link), there is not one Blockchain but, in fact, many different ones. Not all of them follow the same rules, and not all of them are publicly accessible. This time, let’s use some art 🎨 metaphors to examine different types and properties of Blockchains. When it comes to the different kinds of Blockchains, we can differentiate between four main...

Blockchain Explained

First of all, and to clarify, there is no such thing as ‘The Blockchain.’ There are actually hundreds of different blockchains. But to take it one step at a time, let’s look at the general concept of one blockchain, again utilizing a more relatable metaphor from the realms of fashion:Fashion Show = BlockchainImagine a fashion show where each model represents a block in the blockchain. As the models walk down the runway, they are wearing outfits that represent the data or transactions being re...
