Developed with peer-reviewed research and aimed to ensure scalability, security, and sustainability, Cardano is a blockchain based on a proof-of-stake mechanism. The system was created as an enhancement to current blockchains with phased development, which implies new features will be added by means of built-in program upgrades.
Since its inception in 2017, the Cardano blockchain has evolved into a platform for smart contracts, digital asset issuing, dApps, governance, and staking, in addition to conducting transactions with the native cryptocurrency ADA.
It is developed by Charles Hoskinson (Ethereum founder) and is developed by Input Output Global, Cardano Foundation, and Emurgo. The development is based on research, formal verification, and protocol upgrades tested over 5 different eras.
Cardano Development has taken place in the context of 5 eras.
The project was the creation of Cardano in 2015. The network was developed for two years before it was launched in September 2017 during the Byron era, when some innovations were introduced, such as the wallet Daedalus and Yoroi, the Ouroboros proof-of-stake protocol, and the introduction of ADA.
A number of changes were planned for the roadmap, which were implemented:
- Shelley made some improvements to staking and decentralisation.
- Goguen (2021): Used smart contracts and native tokens for the Alonzo hard fork.
- Basho (2022): improved efficiency of the transactions with the Vasil upgrade.
A decentralized governance is in place, as described in Voltaire (2024 onwards), making use of On-chain governance (CIP-1694).
Cards are used in a number of activities throughout the Cardano network. There are several uses to which ADA is put in the Cardano network. It is important to note that ADA is the native cryptocurrency of the Cardano blockchain and has a capped supply of 45 billion tokens. Some of the key activities of ADA are:
- Paying fees using the ADA app.
- Locking up ADA in pools to support the network.
- Using ADA to vote on proposals and upgrading the protocol.
Smart contracts, applications and other digital assets are developed using ADA on the Cardano blockchain.
Cardano Architecture separates Transactions and Smart Contracts
There are two independent layers of Cardano.
The Settlement Layer handles value transfers, user balances, and transactions. The Computation Layer is separate from transaction processing, allowing for the independent operation of smart contracts and decentralized applications.
The blockchain is constructed in the functional programming language Haskell, which is strongly based on mathematics. Cardanoscan confirms that this is a development strategy that is consistent with Cardano’s focus on formal verification and peer-reviewed development.
How Cardano Differs From Bitcoin and Ethereum
Cardanoscan categorizes Cardano as a third-generation blockchain inspired by the ideas of Bitcoin and Ethereum.
Bitcoin was the first to come with proof-of-work to Bitcoin, Ethereum was the first to bring programmable smart contracts to blockchain before moving to proof-of-stake.
Cardano’s Ouroboros has ensured that it has been a proof-of-stake initiative since the initial launch. It also features a multipart architecture, a multi-asset support, structured governance via Project Catalyst and Voltaire period and smart contracts.

Cardano Continues Expanding
After the Alonzo upgrade, Cardano ventured into new areas in DeFi, NFT marketplaces, decentralized exchanges, lending protocols, identity solutions, and token issuance.
Some of the recent developments are:
- The on-chain governance has been expanded in the Voltaire era.
- Hydra is working on becoming a Layer-2 scaling solution.
- Continuous projects aimed at achieving interoperability with other blockchain networks on Cardano.
- Continuous Cardano interoperability projects with other blockchain networks.
Conclusion
Cardano has developed with a well-planned development roadmap that focuses on research, peer review, and gradual network upgrades.
Since then, the blockchain has expanded its capabilities to support the transactions of ADA, staking, smart contracts, decentralized applications, governance, and digital assets. Its technical design is unique, given its layering, Ouroboros Proof of Stake protocol, and Governance model.
Frequently Asked Questions
What is Cardano?
Cardano was launched in 2017 as a development blockchain that is scalable, secure, sustainable and peer-reviewed.
What are the goals of ADA?
Users can use ADA for transaction fees, as a stake for securing the network, as a voting option for governance and as a smart contract and decentralised application.
What is the method used by Cardano to validate transactions?
The Ouroboros proof-of-stake consensus protocol is deployed in Cardano, as stake pool operators validate transactions, unlike energy-heavy mining.
