Cardano is a decentralized proof-of-stake (PoS) blockchain designed as a more efficient alternative to proof-of-work (PoW) networks. It uses its native token, ADA, to process transactions and support a wide range of applications. While it handles various transaction types, Cardano’s broader vision is to become the "internet of blockchains"—an ecosystem where different blockchains interoperate seamlessly. It aims to serve as a platform for innovators and changemakers, offering banking solutions to the unbanked worldwide.
Developed through peer-reviewed research and evidence-based methods, Cardano distinguishes itself from many fast-moving cryptocurrencies. Its deliberate, structured development approach helps identify potential threats early, fostering reliability and long-term sustainability.
How Does Cardano Work?
Cardano operates on a proof-of-stake consensus mechanism, which is more energy-efficient and scalable than the proof-of-work model used by networks like Bitcoin. Here’s a breakdown of how these systems work:
Proof of Work Explained
Decentralized cryptocurrency networks require a way to prevent double-spending without central authorities like banks. Proof of work (PoW) achieves this by relying on computational power:
- Miners compete to solve complex mathematical puzzles using significant computing resources.
- The first miner to solve the puzzle updates the blockchain with verified transactions and receives a cryptocurrency reward.
Proof of Stake Explained
Proof of stake (PoS) replaces miners with validators who stake their tokens to secure the network:
- Validators are chosen based on the amount of ADA they hold and how long they’ve held it.
- The selected validator confirms the latest block of transactions, and others attest to its accuracy.
- All participating validators receive rewards proportional to their stake.
- Users can also delegate their ADA to staking pools to earn rewards without running a node.
Founded in 2015 by Ethereum co-founder Charles Hoskinson, Cardano launched in 2017 as an Ethereum alternative. Both platforms support smart contracts and decentralized applications (DApps), but Cardano emphasizes scalability, sustainability, and interoperability through features like sidechains and selective metadata for real-world use cases.
Key Features of Cardano
Cardano offers several advantages over traditional blockchains:
- Energy Efficiency: Cardano consumes 99% less energy than PoW blockchains like Bitcoin, making it environmentally friendly.
- Scalability: The network handles over 250 transactions per second, outperforming Bitcoin and Ethereum Classic.
- Low Fees: Transaction costs are minimal due to the PoS model.
- Passive Income: Users can stake ADA to earn rewards effortlessly.
- Dual-Layer Architecture: Separates settlement and computation layers for enhanced efficiency.
- Smart Contract Support: Enables DApp development and complex transactions.
Despite these strengths, Cardano faces competition from larger platforms like Ethereum and faster-growing networks like Solana. Its lower price may reflect reduced demand for network space, but the introduction of smart contracts could drive future growth.
Cardano NFTs
Cardano NFTs (CNFTs) are digital assets traded on marketplaces like JPG Store, CNFT.IO, and AdaNFT. Their unique features include:
- No Smart Contracts Needed: Cardano’s extended UTxO (eUTXO) model simplifies NFT creation with inherent security.
- Cost-Effective Batching: Users can buy or sell multiple NFTs in a single transaction, reducing fees.
- Permanent Metadata Link: Each NFT’s metadata is embedded in the transaction, ensuring uniqueness.
- Low Fees and Speed: Fixed transaction costs and fast processing times.
Staking on Cardano
ADA tokens are acquired through exchanges and stored in wallets for staking. Cardano’s PoS system uses staked ADA to determine which nodes validate transactions and create new blocks. Key points:
- Staked ADA acts as collateral and cannot be spent during the staking period.
- Rewards are distributed based on the amount of ADA staked.
- Users can delegate their stake to pools operated by others for passive income.
What Is Stake Delegation?
Delegation allows ADA holders to assign their staking power to a pool without managing a node. This enables broader participation in network security and reward distribution.
Tokenomics of ADA
ADA has a fixed supply of 45 billion tokens. Its primary uses include:
- Paying transaction fees.
- Participating in governance.
- Staking for rewards.
Distribution breakdown:
- Public Sale: 25.9 billion ADA (57.6%)
- Treasury Reserve: 13.9 billion ADA (30.9%)
- IOHK: 2.46 billion ADA (5.5%)
- EMURGO: 2.07 billion ADA (4.6%)
- Cardano Foundation: 640 million ADA (1.4%)
ADA’s utility extends to DeFi and NFT ecosystems, driving demand as Cardano grows.
