Cardano vs Solana FAQ
- What is Cardano?
- Cardano (ADA) is a proof-of-stake blockchain launched in 2017, designed by IOHK with a research-driven approach. Its Ouroboros consensus was peer-reviewed before mainnet, and it has pursued phased upgrades (Byron, Shelley, Goguen, Basho, Voltaire).
- How does Cardano differ from Ethereum?
- Cardano uses an eUTXO model (extended unspent transaction output) rather than Ethereum's account model. It ships upgrades via hard forks coordinated through Haskell-based Plutus smart contracts. Throughput historically lagged peers, though Hydra L2 rollouts aim to close that.
- What is Solana?
- Solana (SOL) is a high-throughput blockchain launched in 2020. It combines proof-of-stake with a clock-like mechanism called Proof of History to process thousands of transactions per second at sub-cent fees, making it popular for DeFi, NFTs, and memecoins.
- Why does Solana have low fees?
- Solana processes transactions in parallel and compresses state into a single global chain, rather than splitting workload across L2 rollups like Ethereum does. The trade-off is higher hardware requirements for validators and occasional network congestion.
- How do Cardano and Solana compare?
- Cardano (ADA): Research-driven Layer 1. Peer-reviewed Ouroboros consensus, eUTXO model. Launched 2017, runs Ouroboros Proof-of-Stake. Solana (SOL): High-throughput Layer 1. Sub-cent fees, consumer-scale apps, memecoin volume. Launched 2020, runs Proof-of-Stake + Proof-of-History.
