Systems and methods for facilitating confirmation of completion of a transaction for state synchronization over a non reliable network using signature processing are described. One of the methods includes receiving a read request from a first client, sending a last known signature with a context object to the first client in response to receiving the read request, and receiving an appended signature from the first client with a context object for a transaction at the first client. The appended signature includes the last known signature and an increment by the first client. The operation of receiving the appended signature occurs upon execution of the transaction at the first client. The method further includes updating the last known signature to the appended signature and sending the updated last known signature to the first client to facilitate marking of the transaction as complete resulting in a definitive state synchronization.
