Storing data in a dispersed storage network

A computing device of a dispersed storage network (DSN), the computing device comprises:

• an interface;
• memory;
• and
• a processing module operably coupled to the memory and the interface, wherein the processing module is operable to:
• generate a set of write requests regarding a set of encoded data slices, wherein a write request of the set of write requests includes an encoded data slice of the set of encoded data slices, a corresponding slice name, and a transaction number corresponding to the set of write requests;
• send the set of write requests to a set of storage units, wherein each of at least some of the storage units of the set of storage units generate a write response that includes the transaction number and a list of revision levels corresponding to the slice name;
• receiving the write responses from the at least some of the storage units, wherein the write responses includes at least a decode threshold number of write responses;
• determining a most current revision level regarding the set of encoded data slices based on the lists of revision levels from the at least some of the storage units;
• and
• generating a set of write commit messages, wherein a write commit message of the set of write commit messages includes the transaction number and a new revision level for the set of encoded data slices.
