Abstract: The present invention discloses a method for proving digital assets of a transaction platform. An asset transaction platform and a server are involved. The method for proving digital assets of the transaction platform comprises: step 1: taking snapshot of a user identity and a user assets amount of each of all users by the sever; step 2: exporting the snapshots of the user identity and the user assets amount into a user asset list; step 3: setting mathematical hash functions; step 4: generating a merkle tree by using a string combined hash value of each of the users as a leaf node, and storing the merkle tree; and step 5: verifying valid user provisions and the total amount of assets of all users on the transaction platform, and drawing a conclusion.

Abstract: One disclosed example method includes a video conference provider establishing a main meeting of a video conference and multiple associated sub-meetings at the request of a host client device associated with a host of the meeting. The method further includes the video conference provider determining that a self-selection mode for the sub-meetings is enabled and transmitting notifications to participant client devices associated with the participants of the meeting. Each notification identifies a list of sub-meetings from which a participant can select a sub-meeting to join. The method further includes the video conference provider receiving and forwarding a request from a participant client device to connect to a selected sub-meeting, and receiving an automatic approval from the host client device. The video conference provider further connects the participant client device to the selected sub-meeting.

Abstract: One example system for multiple host management of videoconferencing sub-meetings includes a processor and at least one memory device. The processor establishes a main videoconferencing meeting and establishes a host of the main videoconferencing meeting. The host participates using a first host client device. The processor can receive a selection of a participant to be a co-host. The co-host participates in the main videoconferencing meeting from a second host client device. The processor receives a first sub-meeting control input from the second host client device, wherein the first sub-meeting control input identifies an action to perform with respect to a sub-meeting. The system generates a second sub-meeting control input based on the first sub-meeting control input, executes the second sub-meeting control input, and discards the first sub-meeting control input so that the sub-meeting command is associated with the main host.
