Worth knowing

Solana can process a transaction in under 400 milliseconds — faster than a human blink.
Cardano has published over 140 peer-reviewed academic papers underpinning its protocol.
Solana suffered a major 17-hour network outage in September 2021, shaking user confidence.
Cardano's smart contracts (Alonzo hard fork) didn't launch until September 2021 — years after competitors.
Solana's validator hardware requirements are steep, raising centralization concerns among critics.

Cardano's founder Charles Hoskinson is also a co-founder of Ethereum — he basically left the family business to start a rival that moves at the speed of a PhD thesis.
