Cardano stands as a third-generation blockchain utilizing a proof-of-stake consensus algorithm.
ADA ranks among the top ten cryptocurrencies, allowing investors to stake their holdings and earn rewards.
Various platforms support ADA staking, including Daedalus, Yoroi, Exodus, Guarda Wallet, and several cryptocurrency exchanges.
Cardano's blockchain is faster, more energy-efficient, and more scalable than Bitcoin.
Introduction
A common recommendation from financial experts is to include a mix of top-ten cryptocurrencies and promising assets from the top 100 in a diversified portfolio. The leading cryptocurrencies by market cap include Bitcoin, Ethereum (ETH), Binance Coin (BNB), Tether (USDT), USD Coin (USDC), XRP, Binance USD (BUSD), Cardano (ADA), Dogecoin (DOGE), and Solana (SOL). This article focuses on Cardano (ADA), which holds a market capitalization exceeding $13 billion and ranks eighth globally.
Understanding Cardano (ADA)
Cardano is an open-source blockchain that hosts smart contracts and decentralized protocols. As a third-generation blockchain, it aims to resolve key challenges faced by earlier generations, such as Bitcoin and Ethereum. These earlier blockchains often struggled with scalability, transaction speed, and high gas fees.
The History of Cardano
Mathematician Charles Hoskinson, the creator and founder of Cardano, launched the blockchain on September 29, 2017. The development team conducted an Initial Coin Offering (ICO) in 2016, raising over $620 million to fund the project.
Cardano's rollout is structured across five phases: Byron, Shelley, Goguen, Basho, and Voltaire. The Byron phase involved initial testing, Shelley marked the mainnet launch, and Goguen integrated smart contract capabilities.
The upcoming Basho phase will focus on optimization and scaling solutions, while Voltaire will introduce treasury and governance systems.
Significant upgrades like the Alonzo Hardfork and Vasil Hardfork have already been implemented. The Alonzo upgrade introduced smart contract functionality, enabling developers to deploy decentralized applications (dApps) and create non-fungible tokens (NFTs). The Vasil Hardfork, launched on June 29, 2022, enhanced network speed and scalability to better support dApps.
Cardano's Proof-of-Stake Mechanism
Blockchain consensus mechanisms verify transactions to prevent double-spending—a scenario where the same cryptocurrency is used for multiple payments. The two most common mechanisms are Proof-of-Work (PoW) and Proof-of-Stake (PoS).
Cardano uses a PoS consensus mechanism, which is far more energy-efficient than PoW. Through its Ouroboros protocol, nodes that stake ADA are responsible for validating transactions. Validators who stake their coins for longer periods have higher chances of being selected to verify transactions.
Smart Contracts
As mentioned, Cardano is designed to host smart contracts that perform various functions, many of which offer innovative financial services like lending, borrowing, and insurance—without intermediaries. The blockchain's two-layer architecture enhances the security of these smart contracts.
Cardano's Two-Layer Architecture and Security
Cardano's two-layer system boosts both security and scalability. The Cardano Settlement Layer (CSL) handles all transactions and is supported by ADA. The Cardano Computation Layer (CCL) executes smart contracts, allowing developers to build dApps.
Key Features of Cardano
Cardano boasts several standout features that contribute to its top-ten status:
Rapid Transactions
Cardano processes up to 250 transactions per second, resulting in low gas fees—often under $1 per transaction.
High Energy Efficiency
Thanks to its PoS mechanism, Cardano consumes minimal energy. Founder Charles Hoskinson claims Bitcoin uses 1.6 million times more energy than Cardano.
Strong Decentralization
Millions of users participate in Cardano's consensus mechanism, either directly or by delegating their stake to pools, ensuring a highly decentralized network.
What Is ADA?
ADA is Cardano's native cryptocurrency, named after 19th-century mathematician Ada Lovelace, often regarded as the world's first computer programmer. ADA is used to pay gas fees, stake for network security, and will eventually enable holders to participate in governance. Like Bitcoin and ETH, ADA serves as a store of value and medium of exchange. Users can buy, store, send, and receive ADA.
Staking on Cardano
Staking involves locking ADA in smart contracts to earn rewards and help secure the network. It ensures transactions follow protocol rules and maintains decentralization.
ADA holders can participate individually or delegate their stake to pools. Pools with larger stakes have higher chances of validating transactions and earning rewards.
How Do Cardano Staking Pools Work?
A staking pool is a node that aggregates users' ADA to function as a single unit. Pool operators run servers with professional hardware and expertise to process transactions and create blocks.
The network rewards operators for helping prevent Sybil attacks, and these rewards are distributed to pool contributors.
Solo Staking
Individual investors can also run their own nodes and stake large amounts of ADA. In this case, validators keep all rewards but require significant technical resources and upfront investment.
How Cardano Differs from Bitcoin
Although both are top-ten cryptocurrencies, Cardano and Bitcoin differ in several key areas:
- Development Approach: Cardano has a dedicated team of experts overseeing its evolution, while Bitcoin relies on its preset code and community consensus.
- Speed and Efficiency: Cardano processes about 250 transactions per second, compared to Bitcoin's 3–5.
- Reputation and Adoption: Bitcoin enjoys greater recognition due to its first-mover advantage.
- Consensus Mechanism: Bitcoin uses energy-intensive Proof-of-Work, while Cardano uses efficient Proof-of-Stake.
- Supply Cap: Bitcoin has a fixed supply of 21 million coins; Cardano's cap is 45 billion.
Staking Platforms
ADA holders can stake on several platforms to earn rewards and support network security:
Daedalus: A desktop wallet developed by Cardano, offering around 5% annual staking rewards.
Yoroi: A popular web extension wallet with approximately 5% annual rewards.
Exodus: A versatile digital wallet supporting ADA staking with about 4.5% annual returns. It requires a minimum stake of 5 ADA and charges a 2 ADA fee.
Other Platforms: Additional options include Guarda Wallet, Uphold, and various cryptocurrency exchanges. To explore more staking strategies, check out advanced methods here.
Conclusion
Cardano is a third-generation blockchain using Proof-of-Stake consensus. Unlike Bitcoin, it doesn't support mining; instead, users stake ADA to earn rewards and secure the network.
