## Summary

PREDA is a programming model for parallel EVM blockchains that decomposes smart contract transactions into steps executed asynchronously across multiple EVMs, rather than synchronously within one block. The article states that PREDA avoids write conflicts by using a shared-nothing architecture in which each EVM holds non-overlapping contract state, and that relay transactions move execution between EVMs according to data dependencies. In its own experiments replaying historical ETH token transfers, PREDA showed 3.3X to 28.2X higher TPS than Aptos, while the article notes that Sei, Aptos and Sui execute transactions synchronously.
