A device may receive content data from a content provider, the content data including: data identifying content, and data for verifying that the content has not changed. The device may access a blockchain associated with the content data, the blockchain including validation information specifying instructions for validating the content. In addition, the device may perform, based on the validation information, validation of the content to determine a measure of confidence that the content is accurate and store results of the validation in the blockchain as a transaction. Based on the validation results, the device may perform an action.

Implementations of the present specification disclose a consensus verification method, apparatus, and device. In the implementations of the present specification, for each piece of service data, if first consensus verification on the service data fails, a first node determines whether the service data satisfies a predetermined retry condition instead of directly considering the service data to be invalid. If the predetermined retry condition is satisfied, then the service data is stored as service data to be retried. The first node can perform the first consensus verification on the service data to be retried in response to determining that a predetermined retry execution condition is triggered.

This disclosure is directed to an apparatus for real-time routing of an input signal received from a real-time sensor to perform disparate computing operations in a complex computing network, wherein hut for the real-time routing of the input signal, which is necessarily rooted in computing technology, separate input signals would be needed for performing the disparate computing operations.

A method of issuing blockchain-based digital certificates associated with a gemstone comprising receiving from a user a plurality of gemstone records, each record of the plurality of gemstone records comprising a characteristic indicator associated with a gemstone, receiving from the user meta-information related to the plurality of gemstone records, applying a hashing function to each record of the plurality of gemstone records, generating a plurality of fingerprints, generating a hash tree from the plurality of fingerprints, the hash tree comprising a root hash, recording to a digital certificate gemstone smart contract deployed at a digital certificate gemstone smart contract address on a first blockchain network the root hash and the received meta-information, and signing the digital certificate gemstone smart contract with an issuer signature.

A media system that includes one or more smart devices.

A group definition is received via a network interface. Communications are transmitted to destinations, the communications comprising an invitation to associate with the a content sharing group. Authentication data associated with users that accept the invention is encrypted. The accepting users are associated with the content sharing group. A content gallery definition is received. A communication is received that the content gallery is to be shared with the content sharing group. The content gallery is caused to be instantiated on devices of users associated with the group. A content request for the content sharing group is received and the content request is transmitted accordingly to users associated with the group. A content item is received in response the request and the content item is transmitted to user devices associated with the group and enabled to appear in instantiations of the content gallery on the user devices.

A method for configuring replicas in a distributed computing system is disclosed. In one example embodiment, a plurality of replicas with associated bootstrap modules may be created. The same bootstrap module code may be used for each replica, thereby simplifying configuration. Using the bootstrap module, the replicas may automatically configure themselves and self-assign a role for a set of predetermined roles such as master and worker. The bootstrap module may check a predetermined location such as a shared network folder for earlier registration entries and then self-select based on the remaining available roles. The bootstrap module may also store its own registration entry to inform subsequent replicas of the role and network address for the current replica so that they may self-configure correctly.

A method and an apparatus for Wi-Fi connection based on Wi-Fi Protected Setup (WPS) in a portable terminal are provided. The method includes entering a group owner mode of Wi-Fi Direct when enabling of WPS is requested, after entering the group owner mode, entering a WPS session mode where the portable terminal is operable in a WPS registrar mode, determining whether an Access Point (AP) whose WPS session of the WPS registrar mode is enabled or a device whose group owner mode is enabled, exists nearby, and when an AP whose WPS registrar mode is enabled is discovered, disabling the WPS registrar mode and the group owner mode, enabling a WPS session where the portable terminal is to operate in a WPS enrollee mode, and accessing the discovered AP.

A system and method for creating and updating a distributed indexing table for peer nodes in a peer-to-peer network. In one embodiment, a method includes providing, from a first node to a second node of the peer-to-peer network, a first level of a first plurality of levels for a first designator identifying the first node and entered in a first distributed indexing table stored in the first node. The method also includes receiving, at the first node from the second node, a corresponding first level of a second plurality of levels for a second designator identifying the second node and entered in a second distributed indexing table stored in the second node, and updating the corresponding first level of the second plurality of levels for the second designator within the first distributed indexing table of the first node.
