For nearly a decade, Cardano has been one of the largest, most reliable, and secure blockchains, with zero downtime since its launch in 2017.
Cardano runs on eUTXO, an extension of Bitcoin’s UTXO accounting model, with native programmability. Transactions execute in parallel. Multiple assets settle in a single transaction. Fees are known before you submit. Smart contract outcomes are deterministic at the protocol level. There are no failed transactions that eat fees. What you model is what executes.
Cardano also handles tokens differently. Native Assets inherit the same properties as ADA itself, secured directly at the ledger level. No ERC-20 style smart contracts sit between users and their tokens.
Given these architectural differences from EVM chains, a major limitation has always been connectivity: Cardano didn’t speak the same language as the rest of crypto.
