Cardano Vs. Polkadot – Which project is better? What are the differences?

Cardano and Polkadot are two blockchain technologies that have been in the news lately. They are both exciting new developments in a space which is often known for quickly changing and moving targets. In this article, I’ll compare and contrast them to give you a better sense of each project’s strengths and weaknesses, as well as what makes them interesting for developers looking for something different.


The Cardano platform is older than Polkadot and is being developed by a team led by Charles Hoskinson, one of the co-founders of Ethereum. The team’s biggest advantage is that they have already secured private funding which will help them expand their development efforts. Additionally, Cardano has many important features including a proof-of-stake consensus protocol, side chains and academic research. These features are important when compared to the competition because it means that Cardano is being driven by thoughtful design decisions made with security as the top priority. The project also has a unique governance structure which allows it to think outside of the box when developing new technology like side chains and staking protocols.

Cardano’s greatest weakness is precisely that it wants to think outside the box. This is a big risk for a project which is in its early days and might not be able to deliver what it promises. It’s also possible that Cardano will have trouble making enough of its technology available in the open source code repository to be able to execute on its promises. If Cardano does develop well, the level of innovation will be impressive but it could end up being an expensive project if it doesn’t act fast enough.


Polkadot is another blockchain project that was launched in 2016. Unlike Cardano, Polkadot’s target market is developers and it is being developed by a single development team. Polkadot also has a structure similar to that of Ethereum which allows it to offer the same benefits as an open source project. Additionally, it’s structured in such a way that it could work with any other blockchain technology in the future. The advantages this gives Polkadot are two-fold: first, it means that the technology will be available for future projects to use or copy. Second, developers can see how Polkadot will function in various circumstances and test its specific safeguards before rolling out their own version of the technology on other platforms.

Polkadot has many advantages but a similar weakness to Cardano. This is that the team will be much smaller than both Ethereum and Cardano which means that they could end up being less innovative, produce slower code or make poor decisions. Additionally, they will be less familiar with traditional blockchain concepts which means it will be difficult for them to create their own new functionality.

Different PoS protocols

The feature that separates Cardano from Polkadot is the proof-of-stake consensus protocol. Proof-of-stake allows for users to vote on block production using a low computational power. This gives users greater influence over the ledger and provides more opportunity for them to come up with ideas that improve on the previous system. Very few other blockchain projects currently use proof of stake and it does have some flaws, which we’ll look at more closely below.

Polkadot also uses proof of stake to secure its ledger, but it uses a slightly different algorithm called Casper instead of Proof of Stake. It’s important to note that proof of stake is not a silver bullet and is not without its own flaws which we’ll look at in greater detail below. There has been an uptick in interest in proof of stake, especially because it has been proven that it can be a better alternative to the traditional proof-of-work consensus protocols.


The centralization of Polkadot has been one of the biggest concerns of many cryptocurrency enthusiasts. This is because of its governance structure which is in part controlled by a governing council that is run by a small group of people. This leaves it vulnerable to attack from outside groups and can lead to issues like censorship and mismanagement.

On the other hand, Cardano has been praised for its decentralized governance model that is planned to be patent-pending and will require approval from stakeholders before updates can be made using an affirmative vote system.[1] There have been no reports of this being mismanaged or abused, so at least this is a potential step in the right direction for Cardano’s governance structure.


Polkadot claims that it will allow users to stake their coins and earn more rewards for the additional work they do. This is a different approach to proof of stake and proof of service, which are just two of the many methods that can be used for generating new blocks. Most wallets currently don’t have a way to implement the full spectrum of this technology into their software, but this is something that I would like to see in Polkadot’s future platforms.

The rewards currency of Polkadot has a similar structure to the medals from Ethereum’s ERC-20 tokens. This means that it will be possible for users to stake their tokens and receive more rewards. This is similar to how the steem currency works on the steemit platform of Steemit but there have been many complaints about the effectiveness of this reward system. The rewards for staking Cardano have not been discussed in details but will likely be similar to the current rewards for staking tokens on Ethereum’s network.

Inflation rate

The inflation rate for Polkadot has a maximum of 10 % a year. This is an acceptable percentage which will likely not have too many problems in the future. The inflation rate for Cardano has been consistently 2 % a year, which is also a safe rate of inflation. This means that it won’t be excessively high or low and neither project will be subjected to serious economic debacles in the near future.

Maximum token supply

Polkadot claimed that it will have unlimited tokens. This is a large amount of the total token supply for the entire project, which will become difficult to manage in the future. There were several issues with Ethereum that caused its inflation rate to be slashed considerably from what was originally envisioned. It was also claimed that Ethereum has no hard cap and would allow other projects to take up its position as the world’s second largest cryptocurrency by market cap.

Cardano’s maximum token supply is still being developed and will eventually be under review again by the Cardano Developers. At the moment it is 45 billion.

The Future of Cardano and Polkadot

Both projects have a lot of potential. Both have very large and wealthy backing, they want to play by their own rules and achieve a very specific set of goals. Both look poised to compete for developers’ attention in the coming year or two. The biggest question to ask in the coming months and years is whether they can deliver on their promises.

Cardano wants to create a currency that’s more than just a simple cryptocurrency. It wants to reach the mainstream and be practical, useful and secure. In doing so, it will be one of the most interesting projects to watch. The future of blockchain technology is often uncertain but Cardano has many advantages that should make it one of the strongest contenders in the space for years to come.

There are many other projects out there with similar goals, but I think Cardano has more promise for now than its competitors do.

Polkadot looks like an interesting project which has a lot of potential but there is only so much that can be done on the Ethereum blockchain or other similar protocols.

Cardano Vs. Polkadot – Which is a better investment?


The Cardano team and its supporters have their own ambitions and ideas that are different from those of Ethereum, but they don’t seem to want to compete too much with the likes of Ethereum. They are still working on developing their own blockchain from scratch, rather than building off other projects. Their ultimate goal is for it to be a “new generation blockchain,” as opposed to just an improved version of existing blockchains (like Ethereum). It also wants a similar network that supports smart contracts and features which will allow for interoperability with other networks.

In terms of the people behind Cardano, there’s a lot of talent and experience here. Charles Hoskinson is the founder and has the most experience in the space. He was a co-founder of Ethereum and was also responsible for founding Invictus Innovations, which provided support to BitShares, as well as creating several other blockchain projects. The person leading development for Cardano is IOHK CEO, Duncan Coutts. He’s worked on several other blockchain projects in the past, and he has 20 years of experience developing software. This team already has a solid foundation set up at IOHK, but they’re also hiring some people in order to build out their team.

The founder of Polkadot, Robert Habermeier, is also the founder of R3 CEV, which is a large company that’s looking at applying the blockchain to financial transactions. It’s an up-and-comer in the space, so Liston says he’s looking forward to seeing what they’ll do with it. The people behind Polkadot are also a solid team.

Competition and Partnerships

Cardano has many big names supporting the project, including big players like the UK’s Barclays Bank and the Japanese financial giant SBI Group. It has been praised by Jeremy Gardner, who is known for being one of the first people to mine Ethereum. He even collaborated with Charles Hoskinson to build an app that could create smart contracts on Ethereum. They hope that Cardano will be able to provide more stability than Ethereum once it becomes larger, which will improve its use as a financial platform.


Cardano and Polkadot are two blockchain technologies that are looking to make their mark in the world of cryptocurrency. Cardano’s planned features include a proof-of-stake consensus protocol, side chains and academic research. It also has an ambitious roadmap for development which should help it gain momentum quickly if it is successful at delivering its initial promises. Polkadot provides developers with many tools and tools such as test cases, documentation, sample code and hardware support to help them get started quickly. The project is taking a slow and steady approach to development which could leave it behind its competition.


  • Cardano is an open source, decentralized blockchain that’s specifically created to be used as the foundation for other cryptocurrencies.
  • It has many big names supporting it, such as the UK’s Barclays Bank and Japan’s SBI Group. They’re also backed by a lot of talent and experience in the space.
  • Polkadot is another project that launched in 2016. The Polkadot team plans to use proof-of-stake to secure their network while using Proof of Service protocol instead of proof-of-work. They also claim that they will have unlimited tokens by the time they launch their network.
  • Both Cardano and Polkadot have their own ambitions and ideas when it comes to creating their own blockchains. The goal is for them to be a “new generation blockchain” which will be able to provide a useful cryptocurrency platform to the broader public.
  • Cardano has an ambitious roadmap for development, which could help it become more stable than Ethereum once it becomes larger. It has a wide range of support and people backing its development.
  • Both projects have similar features that could appeal to developers who are interested in working on blockchain technology.

Both Cardano and Polkadot are looking to create their own blockchains with their own set of features, which will make them stand out from the crowd.
  • There is a chance that they’ll both succeed in creating useful cryptocurrency platforms that provide high levels of security, stability and usability. But their success will depend on how well they plan for the future and how well they’re able to overcome whatever obstacles come up along the way. Both projects may have similar features but they’re likely to have different approaches and slightly varied goals too.
  • Cardano’s biggest advantage is its strong foundation which should help it become more stable than its competition in the long run. It also has the support of many big names in the space and a large network of people that are willing to support it. The Cardano team is a solid group of committed individuals that are well thought out and have a solid vision for their project.
  • Polkadot’s biggest advantage is its potential to become the second largest cryptocurrency by market cap after Ethereum. It has a lot of potential and there’s a lot of people who believe in its potential. There’s also no hard cap on its supply, so it could grow very quickly in the coming year or two if it becomes successful at developing its platform.
