Most EVM systems have no memory

This article discusses a critical limitation of most EVM (Ethereum Virtual Machine) systems: they lack persistent memory between transactions. While EVM can store data on-chain via storage, many systems built on top of it fail to maintain state across sessions. The author explores how this "memoryless" design impacts dApp development, user experience, and scalability, while proposing potential solutions like off-chain storage and state channel architectures to overcome these constraints.
