Abstract: An identity certificate may be issued to a blockchain node. The issuance may include issuing a first identity certificate to a first terminal and receiving a second identity certificate issuance request that is from the first terminal. A second identity certificate may be issued to the first terminal, and a third identity certificate issuance request is received from the second terminal. A third identity certificate is issued to the second terminal, so that the second terminal forwards the third identity certificate to the third terminal.

Abstract: In one embodiment, a method for collaboratively installing a computer application includes monitoring an installation process of an application. The method also includes determining that the installation process requires remote assistance in order to continue. Also, the method includes sending a remote assistance request to remote assistance personnel at a remote site in response to the determination that the installation process requires remote assistance in order to continue. Moreover, the method includes receiving a response to the remote assistance request. The response includes remote assistance information required for installing the application provided by the remote assistance personnel at the remote site. Also, the remote assistance information and the response to the remote assistance request are invisible to an installer of the application.

Abstract: Embodiments of adjustment of a task execution plan at runtime by a task execution engine configured to receive a plan compilation task, the plan compilation task comprising a task execution plan, are provided. An aspect includes receiving a first plan compilation task by the task execution engine through a plan compilation interface. Another aspect includes modifying a task execution plan of the first plan compilation task in response to receiving a second plan compilation task by the task execution engine, the second plan compilation task comprising a task execution plan for modifying the task execution plan of the first plan compilation task. Yet another aspect includes reading a next task in the task execution plan of the first plan compilation task and initiating the next task by the task execution engine.
