1. A method comprises: generating, by a computing device, 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; sending, by the computing device, the set of write requests to a set of storage units; generating, by each of at least some of the storage units of the set of storage units, a write response that includes the transaction number and a list of revision levels corresponding to the slice name; receiving, by the computing device, 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, by the computing device, 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, by the computing device, 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.
