Cardano was proposed back in 2015 with the release of its foundational research papers. Following a phased and region-specific Initial Coin Offering (ICO), where ADA was distributed through vouchers in some regions like Japan, Cardano officially launched its blockchain and cryptocurrency, ADA, in September 2017.
Cardano was founded by one of Ethereum’s co-founders, Charles Hoskinson, and Jeremy Wood. Hoskinson’s vision for Cardano was to create a blockchain platform that was more methodically developed, focusing on academic research and peer-reviewed processes, different from the more experimental approach of many contemporary blockchains.
The scalability of Cardano is its main focus. It currently handles between 200 and 250 transactions per second (TPS), which is less than some competitors but with a strong attention to security and decentralization. While it is projected to reach thousands of transactions per second (TPS) through its upcoming scaling solutions, known as Hydra.
Cardano utilizes a consensus mechanism called Ouroboros, which is a proof-of-stake (PoS) protocol, making it more energy-efficient compared to Proof of Work (PoW). Ouroboros was the first PoS protocol that had its security formally verified, which ultimately placed Cardano in the frontline in terms of academic rigor.
Instead of mining, Cardano uses staking, where ADA holders can delegate their tokens to the staking pools run by validators. These validators are responsible for adding new blocks to the blockchain. Rewards from staking are distributed according to the stake and promote a decentralized validation process. Cardano has no traditional mining; ADA holders earn rewards for supporting the network’s security without the energy consumption associated with mining.
Cardano has made significant moves in government collaborations. In Ethiopia, Cardano has been working with the government on digitizing students and teachers’ identification, leveraging blockchain for educational purposes. Similarly, in Georgia, there are announced plans for blockchain infrastructure to help the government improve services and stimulate the local tech ecosystem. However, like all cryptocurrencies, it faces its challenges in proving scalability solutions in the real world and keeping community engagement in its governance model.
In terms of network upgrades, Cardano implemented the Vasil Hard Fork in September 2022, which upgraded the performance of the network, especially on smart contracts and transaction throughput. Currently, Cardano is progressing through the Voltaire Era, focusing on decentralized governance. This phase allows ADA holders to vote on future developments and funding proposals, making the community more involved in the evolution of the blockchain.
Cardano is currently working towards a decentralized governance model, with plans for a community-voted constitution; this will be a great step towards a self-governing blockchain. Moreover, the Cardano ecosystem has seen growth in DeFi and NFT projects, with an increasing Total Value Locked (TVL) in its DeFi space, reflecting growing adoption and interest in the capability of the blockchain.
As of December 9, 2024, Cardano (ADA) is trading at approximately $1.22, reflecting a positive trend in line with broader market movements. Over the past month, ADA has seen an increase of approximately 184%, supported by ecosystem developments, the constitutional vote, and the increased DeFi activity on the network. This surge in price demonstrates investor confidence in Cardano’s long-term vision and its steps towards full decentralization. As Cardano continues to evolve into the Voltaire era, which focuses on community-driven governance, it remains one of those projects to keep an eye on.

FAQs
Q1: How does Cardano differ from other major cryptocurrencies like Bitcoin and Ethereum?
- A: Cardano differentiates itself through its emphasis on academic research and peer-reviewed development processes. Unlike Bitcoin’s Proof of Work (PoW) mechanism or Ethereum’s transition from PoW to Proof of Stake (PoS), Cardano was built with Ouroboros, a PoS protocol that was the first of its kind to be formally verified for security. Additionally, Cardano focuses on scalability, system interoperability, and sustainability.
Q2: What are the main phases of Cardano’s development roadmap?
- A: Cardano’s development roadmap includes several key eras: Byron, which established the blockchain’s foundation; Shelley, which focused on decentralization; Goguen, which introduced smart contract capabilities; Basho, aimed at scalability and optimization; and the current phase, Voltaire, which centers on decentralized governance where ADA holders can vote on future developments.
Q3: Can ADA be used for payments in real-world scenarios?
- A: While ADA’s primary use is within the Cardano ecosystem for staking, there are initiatives to broaden its utility for everyday payments. However, its adoption for real-world transactions remains limited compared to more established cryptocurrencies like Bitcoin or Ethereum. Cardano’s partnerships, such as in Ethiopia, are steps toward expanding these practical use cases, but widespread payment adoption is still evolving.
Q4: How does Cardano ensure the security of its network?
- A: Cardano secures its network through Ouroboros, a Proof of Stake protocol that is significantly less energy-intensive than Proof of Work. Security is maintained by allowing ADA holders to stake their tokens in staking pools, where the selection of block creators is randomized based on stake, preventing any single entity from dominating the network. Additionally, Cardano’s protocols undergo formal verification to confirm their security.
Q5: What are Cardano’s plans for scalability beyond Hydra?
- A: Beyond Hydra, which aims to scale transaction processing to thousands per second, Cardano is also looking at sidechains for off-chain transaction processing, Input Endorsers to increase throughput, and zero-knowledge protocols to enhance privacy and efficiency without security trade-offs.
Q6: Is Cardano environmentally friendly?
- A: Cardano is considered environmentally friendly because it operates on a Proof of Stake mechanism, which uses much less energy than Proof of Work systems like Bitcoin’s, making the energy consumption for network operations minimal.
Q7: How can someone participate in Cardano’s governance?
- A: With the advent of the Voltaire era, ADA holders can participate in Cardano’s governance by voting on proposals that shape the network’s future using their staked ADA. Community members can also submit their own proposals for community voting, influencing the direction and features of the Cardano ecosystem.
