The Cardano main-net (Shelley era) has been launched in the middle of the year 2020 and so far it runs reliably and without any issues. There is a lot of scientific work behind Ouroboros Proof-of-Stake consensus and the practice shows that theoretical assumptions seem to be correct. People are asking why Ouroboros does not need to punish dishonest participants. Let’s try to answer the question.

Building a distributed network consensus is hard

Decentralization and security of any network consensus are key requirements for building a cryptocurrency. Network consensus is a digital process with many participants. Participants live in the physical…

In the Cardano ecosystem, you can participate in voting and thus actively influence the future of the project. Let’s have a look at it. We will show you how to do it via the Yoroi wallet.

Introduction

To be able to vote, you need to have a certain amount of ADA coins in your wallet. The balance will decide your voting power. To be able to vote, you need to let it know to the Cardano network. It is achieved by the creation of a voting certificate. The certificate can be created in Yoroi or Daedalus wallet and it is…

The possibility to issue tokens on Cardano increases the utility of the network. It will bring network traffic and new users. After the Mary hard-fork, Cardano will become a multi-asset ledger. Let’s have a look at what it means and what it brings to the Cardano ecosystem.

What are native tokens?

Cardano’s security and decentralization are related to ADA coins. ADA is the cryptocurrency of the Cardano network and you can stake it. You can also send ADA coins from address to address. Besides ADA coins, it will be possible to issue other tokens that will have similar properties as…

People can ask why the IOHK team works on Cardano if we have Bitcoin and Ethereum. Do we really need more public networks? These are fair questions. Let’s answer them.

Technology must evolve

We do not know any digital technology that would have been created once and survive without being constantly improved afterward. Technology must evolve or it gets obsolete sooner or later. Why is it like that? The answer is simple. Every technology evolves so when it is not the case for a given project then others will become mainstream. At least, we have such experience from history.

Have…

Cardano is a public global protocol with open source code. Millions of people can use it every day. The question is who should be responsible for maintaining the global protocol that is supposed to be decentralized?

How software development works

Many people do not understand how software development works. They might think that it is possible to create software that can be used forever as is when it is done. Similarly like a knife or shoes. Once a knife is produced you can buy it and use it for cutting foods. There is a catch. When a knife is blunt…

The adoption of cryptocurrencies is driven by monetary policy and utility. Which one is more important? The adoption of Cardano is more about utility than monetary policy. However, both factors are important. Let’s have a look at it.

Monetary policy vs. utility

Cryptocurrencies are technologies in the first place. However, the financial aspect cannot be overlooked. Both factors have a certain impact on society and thus they are the main drivers of adoption. Projects put the accent on different factors. Cardano is mainly about technology that will help people to solve real-world issues. Bitcoin is more about monetary policy. Both…

A joint partnership of Ergo Foundation, IOG, and Emurgo resulted in the creation of the first stable-coin that is called AgeUSD. It is a crypto-backed algorithmic stable-coin protocol with some significant advantages over popular stable-coin Dai.

Why do we need stable-coins?

The traditional cryptocurrencies like BTC, ETH, or ADA are volatile. It means that the price can go up or down in a short period of time. Sometimes, when the market is turbulent, it can even be 10% or 20% a day. Cryptocurrencies can generally be a good store of value due to their stable and hard-to-change monetary policies. However…

Cardano is to be a social and financial operating system. As such, it must be more than a transaction network on blockchain. It must be easy to extend the basic concept and add new functionalities. Transaction metadata will allow it.

Every transaction has a context

First-generation blockchains are able to store transactions. Every transaction basically says how many coins were transferred from address A to address B and when was it. There is no context that would say something more about transactions. Nobody knows who owns addresses, the reason why transactions were sent, and whether everything was fine regarding the…

The security of public networks is not governed by a centralized authority. It is something that evolves organically with the growth of projects. Let’s have a look at how secure Cardano is.

Security of public networks

Security of public networks depends on a group of people that are willing to spend their time and money in order to maintain blockchain networks. Nobody hires these people and gives them permission. People can freely decide to do so and they can also leave whenever they want. The motivation to maintain a public network is purely economical. …

Smart contracts technology has enhanced the abilities of blockchain networks and added programmability features. A trusted link between the digital world and the physical could be another such enhancement. Oracles can do that for us.

Why do we need Oracles?

The first generation of blockchain networks was able to transfer value from

Alice to Bob. They can be perceived as transaction networks. The second generation came with smart contracts. It enables us to work with conditions. It is very useful in an environment where people do not trust each other and it is needed to be sure that something is…
