It is taking advantage of unique account structure of Solana – executable and non-executable accounts and PDAs (Programmatically derived addresses). Using PDAs, the execution for accounts can be delegated to an Ephemeral rollup which could have its own customised block production time, gasless trasactions.
The key components for MagicBlock are

- Provisioners are a network of nodes that spin up new instances of Ephemeral rollups on receiving requests.
- Validators are hyper-specialised an
