 ## Managing public and private state in async transitions
 
 Updating private state on Aleo utilizes off-chain proof generation to preserve the confidentiality of the user’s data and associated address.  Therefore, Records cannot be created or consumed within the scope of `async functions`.  However, Records can be used inside of the scope of `async transitions`.  This is because transition and async transition functions are initially executed off-chain and are accompanied by proofs of correct execution which are subsequently verified by validators.  Once the proof is verified, validators execute the code contained within a Future, which is solely defined by code within an `async function`.
