Abstract
An embodiment of a method of seeking consensus among computer processes begins with a first step of saving a new timestamp in a timestamp array for a particular process. The method continues with a second step of determining whether a most recent entry in a decision array includes a previously established consensus decision. In a third step, if the most recent entry does not include the previously established consensus decision, the method saves a proposed decision as a consensus decision. Otherwise, in a fourth step, the method saves the previously established consensus decision as the consensus decision. In a fifth step, if a most recent timestamp in the timestamp array continues to be the new timestamp, the method returns the consensus decision. Otherwise, in a sixth step, the method returns an abort indicator.
