Overview

ACE offers a two tiered method for ensuring the validity of hashes. The first tier involved calculating a summary value (CSI) for a set of hashes given to the IMS. These CSIs are composed of all hashes for a given time period (round). This CSI can be used to validate any hash submitted during its round. The second tier involves periodically publishing a witness value that is calculated from all CSI values issues during the previous day.
