Introduction
The blockchain space is teeming with projects aiming to challenge Ethereum's dominance, but two stand out as leading "Ethereum killers": Cardano (ADA) and Solana (SOL). This in-depth comparison explores their origins, similarities, differences, and future potential to help you understand which might better suit your needs.
Cardano Overview
Launched in 2017, Cardano is a Proof-of-Stake (PoS) blockchain platform with a mission to redistribute power from centralized structures to individuals. Founded by Charles Hoskinson, Cardano distinguishes itself through:
- Peer-reviewed research: First blockchain to incorporate academic collaboration
- ADA cryptocurrency: Used for transactions and staking rewards
- Sustainability focus: Aims to create positive global impact
