Techniques for managing distributed state for stateless transactions are disclosed herein. In some embodiments a distributed state manager detects a state-changing event that corresponds to a stateless transaction between a node and an application server. The stateless transaction is generated from a first instance of an application that is executing on the node and hosted by the application server. The distributed state manager records the event in a blockchain comprising blocks that each record a batch of one or more events associated with execution of the application. The distributed state manager detects an update to the blockchain associated with the recorded event and modifies a state of a second instance of the application executing on at least one other node based, at least in part, on the update to the blockchain.
