Major improvement in CMO.grexel Transaction Speed
CMO.grexel can now process transactions three times faster than before. In registries, certificates are stored in bundles consisting of a set of certificates with equivalent properties such as production time, country of origin and details of originating production device. One transaction can contain several certificate bundles. For example, a month of production of a hydro device can be in one certificate bundle of 50 000 certificates. Committing a transaction with a certificate bundle is a rather complex operation itself. A certificate registry needs to perform many validations and checks before it knows whether such transaction is allowed and what are the consequences.
