Cardano Get Started

Welcome to the Cardano Developer Portal. This content is for technical people; if you are looking for a Cardano wallet please head to the showcase section.

It is noteworthy to mention that the Developer Portal covers everything you can do today on the Cardano mainnet. If your goal is to learn about Cardano's smart contracts, please visit this signpost article to point you in the right direction.

What is Cardano?#

Cardano is a collection of open-source, patent-free protocols. It's a platform that enables you to store, transform, and manage value, identity, and governance. Cardano follows research not opinions or bias.

How did it start?#

Cardano started as a significant research and development project in 2015, and it took almost two years of research to get to a position to start writing code.

The purpose of Cardano was to ask: How can we build a sustainable financial and social operating system for billions of people? What collections of technologies do we need to bring together to get everything at an affordable cost?

Besides cryptographic research, there was game-theoretic research, identity-management research, and programming-language research. This academic rigor process produced more than 100 academic papers. Most were accepted in cryptography conferences like Eurocrypt and Asiacrypt and went through the standard peer-review process. For example, the paper “Ouroboros: A Provably Secure Proof-of-Stake Blockchain Protocol” was one of the most cited security papers from 2015-2019.

What you need to bring#

To get the most out of the Cardano Developer Portal, you should have programming experience and a basic understanding of blockchain concepts of Cardano such as UTxO, transactions, addresses, key derivation, and networking.

If you are unfamiliar with these terms, start with technical concepts, and you can complete the stake pool course afterward. It will also help you understand basic concepts, even if you don't want to run a stake pool.

Cardano is different#

If you have experience with other smart contract platforms and want to start building on Cardano, it is vital to know its differences:

  • It makes sense to get your head around the concept of UTxO and later the extended UTxO model.
  • Tokens on Cardano are not built with smart contracts. Instead, tokens are native and live on the ledger. The protocol treats them as first-class citizens, like ada. It is quite different from our peers that don’t have native tokens and need to use a smart contract to send tokens.
  • Native tokens use the core infrastructure, and the network has to do everything else instead of running a smart contract and calling a method called 'transfer'. On Cardano, you are sending a standard transaction. This removes a layer of extra complexity and the risk of human mistakes, as the ledger handles all token-related functions.

Why build on Cardano?#

  • Cardano offers a better infrastructure to build products because it is faster, more secure, and cost-effective.
  • Cardano offers accurate cost predictability when it comes to transactions. There are no auctions for transaction fees.
  • Cardano has an energetic community and more than one million wallets. If you stick to specific standards, we are keen to try out and engage with new products. Participating now makes you a first mover.
  • Cardano brings its venture fund. If you build on Cardano you can get your project funded. Every 6 to 8 weeks, projects can be proposed, discussed, and voted on by the Cardano community.
  • Cardano is a proof-of-stake blockchain. By design, it consumes much less energy and computational power.
  • Cardano is built with the rigor of high-assurance formal development methods. The consensus mechanism Ouroboros was delivered with several peer-reviewed papers presented in top-tier conferences and publications in cybersecurity and cryptography. If you build on Cardano, you build on this foundation.
