Cardano's Approach to Combining UTXO and EVM
Cardano is attempting to combine the UTXO model with expressive contracts, attaching arbitrary data to coins to enable richer logic. However, this approach has led to the need for off-chain batchers to handle concurrency issues, which introduces centralization. The article discusses the potential of eCash, which aims to build expressive but scoped contract capabilities on a solid UTXO foundation without the baggage of EVM, potentially offering better scalability and avoiding the need for EVM parity.
