Ethereum and Cardano are the two most well-known block platforms for decentralized applications (DApp). Both projects are trying to create a convenient environment for the development of decentralized applications and smart contracts. However, on this similarity between them ends. Platforms differ significantly from one another both in terms of consensus building mechanisms and internal arrangement.

Consensus Algorithms
Currently, Ethereum uses the Proof-of-Work (PoW) algorithm to maintain the network. However, this will not last forever. Soon, the transition to Proof-of-Stake (PoS) is planned. To solve the problems with scalability should Casper - the new PoS-algorithm Ethereum.

Before fully migrating to PoS, Ethereum will work for a while on the hybrid PoW / PoS algorithm. Having convinced of the stability of the PoS, the developers will activate the "bomb of complexity", after which the ether will not be able to be extracted using ordinary mining.

Cardano implements a kind of Proof-of-Stake called Ouroboros. The algorithm works as follows:
• Leaders of slots check transactions and create blocks.
• Any ADA holder (own project cryptocurrency) can become the leader of the slot regardless of the amount of accumulation.
• The algorithm of Follow the Satoshi is used to select leaders.
• The entire process is automatic, and no additional actions are required on the user side.

Programming languages
The main programming language on the Ethereum network is Solidity. The project team has developed it specifically to create smart contracts. Their execution is handled by the virtual machine Ethereum (Ethereum Virtual Machine, EVM).

Cardano uses Haskell and Plutus. Haskell is a functional programming language that appeared in 1990. His last stable version was released in 2010. Plutus is similar to Haskell, however it was developed by the Cardano team.

Architecture
Perhaps the main difference between the two platforms.
Cardano has two layers, CSL and CCL. They allow you to separate the records about the state of accounts from logical operations. This separation provides end-users with control over the confidentiality and performance of smart contracts.
The level of conclusion of transactions Cardano Settlement Layer (CSL) tracks the status of accounts, the computing level of the Cardano Computation Layer (CCL) is responsible for the logic of operations.

At present, Ethereum has only one level. Work on the second in the process. One possible solution is Plasma. Plasma contains daughter blockades, similar to the network of Lightning bitcoins. They ensure the conduct of transactions with minimal involvement of the main detachment.
In addition, soon, Ethereum should appear shading. All these technologies will significantly increase the network bandwidth and solve the problem of scaling.

Other differences
In addition to the obvious difference in capitalization and price, the cryptocurrency has some less critical features.
Ethereum is older than Cardano for more than three years. The first project was launched in January 2014, the second was launched only in September 2017.
Cardano has one of the largest offers of coins in the industry. In total, it is planned to issue 45 billion ADA tokens. Ethereum does not have limits on the number of coins; at the moment it is just over 101 million.
Ethereum is one of the largest and most active (if not the largest and most active) development communities in the crypto-currency industry. Most of the initial coin placement (ICO) takes place on the Ethereum blockhouse. The cost of the ether will grow, while the popularity of the platform remains at a high level.
Cardano can not boast of such high popularity, but the crypto currency has a loyal and friendly community. The main tests are waiting for it after the preliminary stage, when the platform will be fully ready for the development of decentralized applications. The long-awaited release can significantly increase the popularity of Cardano and raise its price.

Thank you all for attention!

Cardano is better than ETH is very aspect. Given this coin is new and offers better rates than ETH, Cardano has potential in the market.

Given the popularity Cardano has gained in the short period of time, it does look like a better alternative to ETH.

Thank you for taking the time and effort to share this with us. We all know cardano and ethereum are two unique cryptocurrencies and both are market dominants. However, there was so much hype with cardano back in 2017 and many thought that this coin would rocket in 2018. But we haven’t seen much progress from it and now I’m not so sure where it’ll end up in the future.

ETH is doing really great but now it time to face their competitor because Cardano is doing really great which is potential than ETH.

I like ethereum rather than cardano. Ethereum is the top in the cryptomarket. it follows the decentralized system and also runs with smart contact. for run smart contract they use new programming language named solidity and that is interesting. their project purpose also good.

You are right, every platform is different from each other. But some have most potential features and some have a little. I hope Cardano will do better for beusing their best decentralized platform.

I think ETH coin is in crypto not from so long so it needs more time to grow and to be successful. Instead of having some big catastrophe they are now trying to make their position by improving them.

Ethereum is an established coin. So it's quite hard for Cardano to beat Ethereum. Still it has some possibilities. Cardano is much fast which makes it better in some points. But it needs to be established first.

There are some differences between them. Though both of them serves the same purpose. Still they differs from efficiency, speed, etc factors. Like Ethereum has less transaction speed than Cardano.
