Abstract: The system, method, and computer program product described herein provides a built-in feedback mechanism for a blockchain to sanction validator nodes that consistently “vote” in a manner that does not match the ultimate consensus. The method includes receiving a vote on whether to add a transaction to the blockchain, comparing the vote to a consensus decision on whether to add the transaction to the blockchain, determining based on the comparison that the vote does not match the consensus decision, in response to determining that the vote does not match the consensus decision, incrementing a value associated with the validator node in a feedback registry, determining that the value associated with the validator node is above a predetermined threshold value, and in response to determining that the value associated with the validator node is above the predetermined threshold, proposing a sanction of the validator node to the plurality of validator nodes.

Abstract: An example operation may include one or more of identifying a workflow specification including a number of entities and state elements, selecting two or more entities designated as a subset of entities among the entities, where the subset of entities share one or more of the state elements of the workflow specification among the state elements, and creating a first smart contract identifying the one or more state elements.

Abstract: An example operation may include one or more of identifying a registered interest associated with a requestor on a blockchain, accessing a smart contract stored on the blockchain, determining a match between the registered interest and blockchain transaction information, determining the requestor associated with the registered interest has access permissions to access the blockchain transaction information based on access control rules, and creating a temporary bilateral smart contract including the requestor, and an owner of the blockchain transaction information, and the temporary bilateral smart contract provides permission for the requester to access the blockchain transaction information.

Abstract: An example operation may include one or more of receiving an identification of vendor resources held by each of a plurality of members of a social network, extracting respective preference information of the plurality of members from web pages associated with the plurality of members on the social network, automatically determining to exchange resources of a first vendor issued to a first member of the social network with resources of a second vender issued to a second member of the social network based on extracted preference information of the first and second members, and triggering execution of the exchange of resources via one or more blockchain computing networks associated with the social network

Abstract: An example operation may include one or more of a processor configured to receive a database command from a client system, the database command comprising a database function and parameters to be used by the database function, and to execute the database command on database data, and an interface configured to transmit the database command to one or more other databases that are within a decentralized database system in which each database node is controlled by a different entity, wherein in response to receiving a request from an ordering node of the decentralized database system, the processor may commit results of executing the database command to a database and store information about the database command in an append-only immutable database log.

Abstract: During a process of migrating a source system into a standardized virtual environment, virtual machine instances of the source system executing in a hypervisor are snapshotted as virtual machine images in an operational repository of the hypervisor. The virtual machine images in the operational repository are short-term snapshots. From time to time during the migration process, long-term snapshots of the source system are created by checking given ones of the virtual machine images from the hypervisor operational repository into an image library as image objects.

Abstract: An arbitrary customer instance is transferred from a customer environment to a target managed-infrastructure-as-a-service cloud environment as a transferred image. An image adjustment plan, capturing at least one adjustment required to render the transferred image compliant with standards of the target managed-infrastructure-as-a-service cloud environment, is formulated. The image adjustment plan is executed to adjust the transferred image to obtain an adjusted image compliant with standards of the target managed-infrastructure-as-a-service cloud environment. The adjusted image is on-boarded into the managed-infrastructure-as-a-service cloud environment as a standard image thereof.

Abstract: An example operation may include one or more of storing a user profile in a blockchain by an authorized member of the blockchain, receiving a request by another authorized member of the blockchain to access the user profile, identifying the request for the user profile is from the another authorized member of the blockchain, creating a signed message that includes consent to share the user profile with the another authorized member of the blockchain, and transmitting the signed message to the another authorized member of the blockchain, and wherein an exchange of the user profile between the blockchain members is performed without revealing blockchain member identities of the authorized member of the blockchain and the another authorized member of the blockchain to any of the blockchain members.
