The technical rollout of the Secure Chain takes place by expanding existing services in the Port Community System (PCS) of the Dutch ports by means of an extra authorisation layer. Parties in the port logistics chains have been quickly and conveniently exchanging digital data with one another via this PCS for more than twenty years already. T-Mining’s Secure Container Release is a separate blockchain solution. Of course, shipping lines/ship agents are free to make their own choice from the available solutions for releasing containers. In all cases, the inland operator will however always need to submit a pre-notification to the container terminal via Portbase prior to collecting containers.
