Abstract: An example operation may include one or more of changing a status of a current blockchain to a closed and retired status based on expiration of a limited time window, creating a genesis block associated with a new blockchain, storing a world state of the current blockchain in the genesis block, creating one or more smart contracts, storing the one or more smart contracts on the new blockchain, and initiating an open stage on the new blockchain, and the open stage permits one or more potential blockchain transactions to be written to the new blockchain.

Abstract: A system, method and program product for creating a customized content viewer portlet from a content viewer portlet template. The system comprises a content viewer portlet template that is imported into a workbench. The content viewer portlet template includes a persistent interface component, a model component, a view component and a controller component. The persistent interface component is configured to connect to and retrieve data from a content management system, with the retrieved data being stored in the model component. The view component is configured to retrieve the data from the model component and to display the data as content items. The controller component is configured to invoke methods to be executed by the persistent interface component and the view component in response to a user request, such that the content viewer portlet template is transformed into the customized content viewer portlet that can be installed into a desired portal.
