#CardanoDebate

Comparison of Cardano with other blockchains (Solana, Ethereum, Polkadot)

Feature Cardano (ADA) Ethereum (ETH) Solana (SOL) Polkadot (DOT)

Consensus Proof of Stake (Ouroboros) PoS (since ETH 2.0) Proof of History + PoS Nominated PoS

Speed TPS ~250 TPS (can scale with Hydra) ~30 TPS (more with rollups) ~65,000 TPS ~1,000 TPS (depends on parachains)

DeFi Ecosystem Limited but growing Very broad and mature Fast growth, active dApps Moderate, focused on interoperability

Contract language Haskell (Plutus) Solidity Rust Rust/Substrate

Strength Academic rigor, sustainability Dominance in the DeFi and NFTs market Speed, user-friendly UX Interconnection between chains

Weakness Slow development, fewer dApps High fees during congestion Centralization risks Lower overall visibility

Cardano vs Ethereum: Cardano is more “formal” and sustainable, but Ethereum leads in real use and DeFi ecosystem.

Cardano vs Solana: Solana is faster and has many active dApps but has had more technical interruptions. Cardano is more stable, although slower in innovation.

Cardano vs Polkadot: Both bet on interoperability, but Cardano has a stronger community and greater capitalization.

🌍 Real adoption and use cases

1. Projects in Africa

IOHK (now Input Output Global) works with governments in Africa, especially in Ethiopia, where Cardano implemented digital identity solutions for students.

Meta-goal: to provide digital identity and banking access to unbanked populations.

2. Use cases in health and education

Cardano seeks to use its blockchain to:

Verify educational credentials.

Create decentralized medical systems.

Applications in medicine logistics and supply chain.

3. DeFi and NFT (evolving)

DeFi ecosystem still limited but growing with platforms like Minswap, SundaeSwap, Liqwid.

Cardano has supported NFTs since 2021, with markets like JPG Store.
