This article aims to give an overview of tips and techniques for saving gas cost when creating a Smart Contract. The article is divided into two parts. The first part focuses on some general guidelines and technique on how to create a Smart Contract. The second part tries to use Read more

If you have missed the previous parts, you can find part 1 here and part 2 here. In this part, we will take a look at some selected DeFi services like NFTs and decentralized exchanges. NFTs First, we need to understand what an NFT is. An NFT (nonfungible token) is Read more

If you have missed part 1 you can find it here. In this part, we scrutinize the settlement layers 1 and 2. They serve as a foundation of decentralized finance services and thus influence their decentralization. In some cases, there is even a strong connection between the settlement layer and Read more

In this blog post series, we will take dig into the question of how decentralized DeFi is. The aim is to create awareness of aspects that influence the decentralization of these services. Since DeFi is a vast space, we can only set spotlights on certain services and aspects. In the Read more

This is the final part of two articles about the usage of tokens in e-learning.

It is one thing to earn tokens, but it is also important to know how a user can spend them. That’s why we look into how users can utilize their earned tokens. If you have missed the first part on how to earn tokens, you can find it here.

This is the first part of two articles about the usage of tokens in e-learning. In this article, we explore the usage of tokens in an e-learning platform and how they can enhance the acceptance of the platform and increase the learning success. The article is divided into two parts. First, we take a look at how students can obtain tokens and second, we take a look at how they can spend the tokens.

The Gas Station Network (GSN) is a decentralized meta-transaction framework. It allows users without Ether to make an Ethereum call into the blockchain by having a third party pay the gas costs. This way, a DApp can be accessed by more users who have been deterred by buying Cryptocurrencies and the associated KYC Process. These users could pay with fiat or token in the application, but would not need Ether for the transaction fees. 

This article covers the implementation of zk-rollups using zk-Sync library accessed from github for testing purposes. We have also summarised some issues encountered during the implementation while using the zk-Sync library.

In this post, we explain in detail how zk-rollups and optimistic rollups work.
