When investing in virtual currency, you need to do your research. We provide you with reviews of each world top cryptocurrency out there, so that you can find the best crypto coins to invest in for you. This is a review of Cardano Coin.

What is Cardano?

Cardano is an open source blockchain technology project. Like many other similar projects, Cardano as a project includes both a platform and a cryptocurrency. Cardano’s cryptocurrency has the trading ticker ADA. It is currently one of the top 10 biggest cryptocurrencies in the world by market cap.

Cardano launched 29 September 2017, after two years of development. Ethereum was the first blockchain to characteristic smart contracts. Nowadays, a number of others cryptocurrencies follow the same smart contract functionality. One of those is Cardano.

Cardano claims to be the first blockchain platform to grow out of a scientific philosophy. An international team of engineers and researchers have vigorously developed the cryptocurrency. The project began in 2015. Interestingly enough, the former Ethereum CEO and co-founder Charles Hoskinson is leading the project. Hoskinson left the Ethereum project before the network launched, and ultimately went on to found IOHK.

The platform is completely open source and patent-free.

How Does Cardano Work?

Up until today, Ethereum has been the dominant player in the world of smart contracts. Many believe, however, that Cardano can be a strong future competitor to Ethereum on the smart contract-arena.

Cardano claims to have extra superior aspects than any other protocol ever developed. The development team claims that its cryptocurrency is the most perfectly engineered cryptocurrency yet. The platform integrates concepts like disseminated systems, mechanism design, and cryptography. Also, the Cardano cryptocurrency is the first to be based on Haskell code, an industrial-strength programming language.

The blockchain uses an exclusive proof of stake (POS) algorithm known as Ouroboros. Also, it has an introductory settlement layer linked to a control layer. That settlement layer has a unit of account, while the control layer runs on smart contracts. Furthermore, the control layer will be programmed to make out identity, assist fulfilment, and enable blacklisting, among other purposes.

One of the instant distinctions from Cardano is that it’s designed to stick to regulators while still maintaining user seclusion. Cardano also claims to be the first protocol that balances these necessities. Some believe Cardano to be one of the more future-proof platforms for just that reason.

The cryptocurrency industry has created lots of opportunities for new exciting projects to enter the market — one of them is Cardano and its coin!

The technology that the Cardano uses is brand new, so I am going to give you a complete guide on everything you need to know. Firstly, I will explain what Cardano is and what are the main aims of the company.

After that, I will explain how the technology works, using really simple real-world examples as well as provide a list of Cardano’s advantages and disadvantages that will help you to decide whether ADA is worthy of your attention.

Before buying ADA, make sure to choose a reliable cryptocurrency exchange, such as Binance, and store your tokens in a secure wallet. The most recommended options include Ledger Nano S and Trezor.

The Core of Cardano

The Cardano project started in 2015. The company behind its development is called Input-Output Hong Kong (IOHK), which is managed by the co-founder of both BitShares and Ethereum, Charles Hoskinson.

The aim of Cardano is to create a blockchain that can perform much better than older blockchains like Ethereum, meaning that it should process more, cheaper and faster transactions.

Charles Hoskinson believes that Cardano is a third-generation blockchain, whilst Bitcoin and Ethereum are first and second. So, rather than copying the code of other blockchains, IOHK has created its own new blockchain.

People sometimes think that Cardano and ADA are the same, however, there is a slight difference. Cardano is the name of the blockchain that allows people to send and receive funds. ADA coin is the name of the cryptocurrency.

Ada token: Cardano front page.

This is similar to how Ripple works, where Ripple is the name of the blockchain and XRP is the name of the cryptocurrency.

The Cardano coin blockchain will also allow people to create smart contracts, just like the Ethereum blockchain. Smart contracts allow two or more people to enter an agreement without needing a third party, meaning that once pre-defined conditions have been met, everything else is automated.

Like most other blockchains, Cardano is decentralized, meaning that it is not controlled by any single authority. Instead, transactions and smart contracts are verified by the community, who do so by contributing their computing power. However, Cardano does things differently from Bitcoin and Ethereum (I will explain everything more detailed later).

To help raise funds for the development of Cardano, the team raised $63 million during its ICO. Since then, the ADA coin has reached heights of $33 billion in market capitalization!

Note: ICO stands for “Initial Coin Offering”. It is a way for cryptocurrency companies to raise funds. In the first three months of 2018 alone, more than $6 billion was raised in ICO’s!

ADA coin: Cardano features.

So, now that you understand how Cardano and the ADA cryptocurrency started, as well as what they plan to do, then the next part of my guide is going to explain how it works.

How Does Cardano Work?

First, it is important to understand how the Cardano blockchain functions. It can be split into two different layers:

  1. Settlement Layer: The settlement layer has been built and is now fully operational. This allows users to send and receive ADA coins, wallet to wallet. This is similar to how users can transfer Ethereum (ETH) to each other.
  2. Computation Layer: The computation layer is still being developed. Once it is launched, it will allow users to create and enter into smart contracts.

That’s why Cardano is different from the earlier blockchains that normally operate on a single layer. Two separate layers bring some potential benefits to Cardano users.

Firstly, the computational layer is more adaptable than the likes of Ethereum, as small changes can be made for different end-users. For example, since different nations have their own regulations, Cardano can change how data is stored and accessed depending on their laws.

To make sure you understand how both settlement and computation layers work, here is a quick real-world example.

  1. John needs to hire an electrician to fix his kitchen lights.
  2. John enters into a smart contract agreement that is stored on the computation layer.
  3. The agreement states that as soon as the electrician has fixed John’s lights, the agreed funds will be released.
  4. When this happens, the smart contract is transferred to the settlement layer, which allows the electrician to be paid in ADA cryptocurrency.
  5. Everything is fully automated, meaning that there is no need for a third party.

So, now that you know the difference between the settlement layer and the computation layer, I will now explain how the transactions are verified!

How Are ADA Coin Transactions Verified?

I mentioned earlier that the Cardano platform is decentralized, meaning that no single authority has control over the network. This means that the network is operated by miners.

However, Cardano uses a different model, which it calls “Ouroboros”. Before I explain how it works, let me quickly explain how other blockchains like Bitcoin are different.

Bitcoin uses a consensus model called “Proof-of-Work”. To help authenticate a transaction, miners use their computing power to solve a really difficult puzzle. It’s like a mathematical equation that is so difficult, no human being could solve it!

Whichever miner solves the puzzle first, they get the reward that is paid in Bitcoin! The problem with Proof-of-Work is that as the puzzle becomes more and more complex, miners need to use more and more electricity.

In December 2017, it was reported that Bitcoin Proof-of-Work miners were using more electricity than the entire nation of Ireland! Not very economical, right?

The Cardano network confirms transactions using a consensus mechanism called Proof-of-Stake:

  1. People who want to help validate transactions are called validators.
  2. Validators must freeze some of their ADA coins, which is called the “Stake”.
  3. Once a validator helps verify a transaction, they receive additional ADA cryptocurrency as a reward.
  4. The higher the stake, the more chance a validator has of receiving the reward!
  5. The amount of coins they receive is based on how much “stake” they have.

This system is far more efficient and environmentally friendly than Proof-of-Work as it requires much less electricity, which means transaction fees are lower as well.

ADA coin: proof of work and proof of stake.

Although there are other Proof-of-Stake blockchains available, the Cardano team says that none of them offer a truly random way of selecting a validator. This is why they built their Ouroboros protocol on top of the standard Proof-of-Stake model, as it ensures everybody gets a fair chance of earning the reward.

This is sometimes called “The Honest Majority”, which means that if people have a big stake in the blockchain (for example, having lots of ADA coins), then they have a reason to make sure that the network remains secure, stable and most importantly – honest.

So, now that you know how transactions are confirmed and validated, let’s see how the Cardano platform performs!

Is Cardano Scalable?

There are so many different blockchains in the market, and it is important to understand what makes each of them unique. One of the most important things to consider when deciding how well a project can perform is its scalability.

In the cryptocurrency industry, scalability is how many transactions a blockchain can process in a certain time-frame, however, it is normally presented as “transactions per second”.

Older blockchains like Bitcoin and Ethereum have big problems with scalability, as they are very limited to the number of transactions they can process at one time. In fact, Bitcoin can only process 7, while Ethereum averages a maximum of just 15. Again, this is where Cardano has an advantage.

When transactions are verified on the Bitcoin blockchain, they remain on the public ledger forever. This means that over time, the blockchain ledger becomes bigger and bigger.

The problem with this is that every single miner on the network must keep a copy of every single transaction. This causes scalability issues.

ADA token: native token.

Cardano, however, is building a blockchain that does things differently by separating data that is not relevant to the people involved in the transaction. For example, if John sends 100 ADA coins to Sue, they are the only two people that are involved in the transaction.

As a result, when validators help confirm the movement of the funds, they only need to maintain the data that is relevant to the transaction, not the entire blockchain!

The team is also aiming to install a protocol called “Sharding”. The way this works is that as more and more people use the network, the number of transactions per second increases.

Cardano performed a test in late 2017 that allowed the blockchain to process 257 transactions per second, which is significantly more than Bitcoin and Ethereum. However, the long-term aim is to increase this number to tens of thousands per second.

Daedalus Wallet

When it comes to storing your ADA coin, Cardano has its own official wallet called Daedalus. However, there have been many reports from the cryptocurrency community saying that the Daedalus wallet has many issues. This includes things such as being unable to connect to the network, sync blocks and transactions not reaching the receiver.

If you’re looking for the most secure and reliable wallet, you should check out Ledger Nano S and Trezor. Since they’re offline wallets, your assets will remain safe at all times.

Ada token: Ledger Nano S.

So, now that you know about Cardano’s plans for scalability, the next part of this ADA cryptocurrency guide is going to look at what it can be used for, as well as how it could be abused!

How Can Cardano Be Used And Abused?

First of all, ADA Cardano coin can be used in the same way as Bitcoin — a global payment system. However, as I mentioned earlier, Bitcoin can only process 7 transactions per second. No global payments system could survive if it was only about to scale up to 7 transactions per second. In fact, Visa alone processes an average of 1,667 transactions every second!

So, if the Cardano team is able to meet their objectives of “tens of thousands” per second then the network would work perfectly as a payment system.

The second main function of ADA coin is to allow people to create smart contracts and dApps (decentralized applications). This could be anyone from corporations, governments or even individuals.

However, if Cardano is to get their smart contract protocol to go global, they need to improve their scalability issues.

Ada token: what is Ada.

If Cardano is able to meet these objectives, then their technology would be perfect for everyday applications, as it would be near impossible for people to hack and the application would never go offline. It would also mean that confidential data remains confidential!

Criminal Activity

Blockchain platforms like Cardano are perfect for committing an anonymous crime (this is not a recommendation).

But why?

Well, when you send or receive an ADA coin, you do not need to reveal your real-world identity.

Instead, the only thing that people can see is your personal wallet address, which looks something like this:


Allowing people to send and receive funds anonymously means the platform could potentially be used for money laundering or tax evasion. This is because it is near impossible to find out who is actually involved in a transaction.

It also allows people to sell illegal goods and services online without having to reveal any real-world payment details.

Cardano team is also working on a protocol that will allow users to share their metadata if they decide to. Metadata carries certain information about a transaction, such as:

  • What did X spend the cryptocurrency on?
  • Who did X give the coin to?
  • Where did X get her ADA coin from?

The above protocol will allow banks to use the Cardano blockchain, as they will be able to comply with national regulations.

Pros & Cons of ADA Cryptocurrency


  • Great development team. The founder has been working with successful projects, such as BitShares and Ethereum.
  • It will be the first blockchain to use multiple layers (settlement and computational layer).
  • No scaling limit. The more people use blockchain, the more transactions can be processed.
  • The ADA cryptocurrency offers cheap and quick transactions.
  • Cardano’s consensus mechanism is more environmentally friendly than older blockchains, as well as being fairer.


  • The blockchain is still being developed, so some of the Cardano claims are theoretical.
  • Other blockchains, such as Ripple, Stellar Lumens, and NEO can already process more than 1,000 transactions per second.
  • The maximum scalability at the moment is only 257 transactions per second.
  • Ongoing problems with their official wallet.


So, this is the end of this “what is Cardano? guide!

I hope that you found this Cardano and ADA cryptocurrency guide helpful and managed to understand all of the aspects regarding ADA coin.
