In a second embodiment, a respective method that can be carried out by the system is disclosed.

Methods, media, and systems are disclosed for adding new users to a channel in a group-based communication system. The system receives a request to add new users to a channel. The system adds a new user by classifying the new user's email address domain as internal or external. If the domain is internal, the first user is added to the channel as a member, and if the domain is external, the user is prompted for a type of access for the new user. If the new user's access type is guest, the new user is added to the channel as a guest. If the type of access is shared, the channel is shared with an organization associated with the domain, and the new user is added as a member of the channel that has been shared.

A computer-implemented method for validating a digital signature of at least one node in a peer to peer network comprises the steps of, a) executing a gossip algorithm, b) locally calculating in each node, a trust score s assigned to other node of the network, c) locally validating in each node, each digital signature of the at least one node, based on the value of said trust score s of the network, d) if there is a change in at least one trust endorsement value t of a node, sending the changed trust endorsement to each neighbour node and executing step a), or e) if a new node is added or deleted in the network, executing step a). A data processing system, a computer program product and a computer-readable storage medium for carrying out the steps of the method are also described.

Embodiments described herein generally relate to systems and methods that match the need for processing capability with the supply of computing resources. Similarly stated, embodiments described herein generally relate to systems and methods that allow users with a need for computing resources to have their computational problems serve as a basis for cryptocurrency mining. Embodiments described herein also relate to smart contracts such that users with a need for computing resources can stake a payment token such that miners are incentivized to solve a computational problem and are automatically awarded payment upon completion of the computational problem or a subtask associated with the computational problem.

Aspects of the subject disclosure may include, for example, a method including obtaining a first set of votes from devices that are registered and enabled by a registration system to form a first network communicating with a processing system. The first set of votes relate to performance of a target device and indicate conformance to performance criteria for the first network. The processing system receives a reputation score for the target device from the registration system, and receives a second set of votes regarding target device performance from voting systems over a second network comprising a peer network including the processing system and the voting systems. The first and second sets of votes and the reputation score are aggregated to generate an updated reputation score for the target device. The registration system disables the target device when the reputation score falls below a threshold. Other embodiments are disclosed.

Disclosed are an information packet download method for preventing high concurrency, an electronic device, and a non-volatile computer readable storage medium. The method includes: adjusting a current probability of downloading an information packet based on download environment information; receiving an information packet query request for downloading the information packet from a client, and determining whether to allow the client to download the information packet based on the current probability and the information packet query request; and when it is determined to allow the client to download the information packet, sending a download instruction to the client in response to the information packet query request, to make the client download the information packet.
