By radically altering what is stored, @Plasma addresses the "state explosion" issue, which occurs when storing every user's complete history bloats the network. Each #Plasma child chain maintains its own detailed state locally rather than requiring the main Ethereum chain to record every single transaction. Only small, recurring commitments cryptographic snapshots of the final state of the child chain are stored in the main chain. Users only need to present a minimal proof associated with these commitments when they leave the system. No matter how many millions of transactions occur off-chain, this design guarantees that the load on the main chain remains steady and controllable, preventing explosive growth at the core security layer.
