Cardano

Cardano is a layer-1 blockchain founded in 2015 by Charles Hoskinson, one of the co-founders of Ethereum. It was developed by IOHK (Input Output Hong Kong) with a strong focus on academic research and peer-reviewed development. The goal was to create a scalable, sustainable, and decentralized blockchain that improves upon Bitcoin and Ethereum. Cardano is powered by its native token (ADA) and uses proof-of-stake consensus mechanism to support decentralized applications (dApps) and governance (DAOs), token creation and customization, and more.

1. How It Works

Cardano is a proof-of-stake (PoS) blockchain, meaning it does not rely on energy-intensive mining like Bitcoin. Instead, it uses Ouroboros, a PoS consensus mechanism where network participants (validators) are chosen based on the amount of ADA (Cardano’s native token) they hold and stake. The core components of Cardano include:

• Layered Architecture: Cardano has two layers:
  1. Cardano Settlement Layer (CSL) – Handles ADA transactions (like Bitcoin).
  2. Cardano Computation Layer (CCL) – Runs smart contracts and DApps.
• Plutus and Marlowe: Special smart contract languages designed for security and efficiency.
• EUTXO Model (Extended Unspent Transaction Output): A more advanced version of Bitcoin’s UTXO model, making transactions more secure and scalable.

2. Uses in Web3-Supported Games

Cardano is increasingly being adopted in Web3 gaming due to its efficiency and scalability. It supports:

• In-game NFTs – Players can own, trade, and sell items as NFTs.
• Play-to-Earn (P2E) Models – Games can reward players in ADA or game-specific tokens.
• Decentralized Gaming Economies – Game assets can exist outside centralized control, giving players true ownership.
• Low-Cost Transactions – Cardano’s PoS system ensures cheaper transactions compared to Ethereum’s gas fees.

3. Types of Tokens on Cardano

Cardano supports multiple token types, including:

• ADA – The native cryptocurrency used for transactions and staking.
• Native Tokens – Custom tokens created on Cardano without the need for smart contracts (unlike Ethereum’s ERC-20).
• Non-Fungible Tokens (NFTs) – Unique digital assets used in gaming, art, and collectibles.
• Gaming Tokens – Many Web3 games build their in-game currencies on Cardano.

4. Advantages of Cardano in Gaming vs Other Blockchains

Compared to Ethereum, Solana, and Binance Smart Chain, Cardano has several gaming benefits:

• Scalability – The layered design and EUTXO model improve transaction speed and efficiency.
• Low Fees – Gas fees are significantly lower than Ethereum.
• Energy Efficiency – PoS consensus consumes less energy than PoW (Proof-of-Work).
• Security & Reliability – Academic peer-reviewed approach ensures a stable and secure network.
• Interoperability – Cardano is working on cross-chain compatibility, making it easier to integrate with other blockchains.
