Abstract: A scenario execution system includes a scenario execution terminal, a log management device, and a storage device. The scenario execution terminal includes a scenario execution unit and an event notification unit. The scenario execution unit executes a scenario file having a scenario indicating a procedure of operations in the scenario execution terminal described therein. The event notification unit notifies the log management device of information on an event generated by the scenario execution unit executing the scenario file. The log management device includes a log recording unit that receives the information on the event from the scenario execution terminal and records log data having the received information on the event set therein on the storage device. The storage device adds, to the log data, information uniquely generated on the basis of log data recorded before such log data and stores resultant log data.

Abstract: An example operation may include one or more of generating a hashed summary including hashes of one or more of a validation data set and hashes of data points chosen in previous iterations from producer nodes, and exposing the hashed summary to a plurality of producer nodes, receiving, iteratively, a plurality of requests from the plurality of producer nodes, respectively, where each request identifies a marginal value provided by a hash of a data sample available to a producer node, selecting a request received from a producer node based on a marginal value associated with the request, retrieving hashed data of the producer node associated with the selected request, and aggregating the hashed data of the producer node with the summary of hashes generated at one or more previous iterations to produce an updated summary, and storing the updated summary via a data block of a distributed ledger.

Abstract: Systems and methods for transfer of rights pertaining to game assets operate between users of an online gaming platform. Exemplary implementations may: tokenize a game asset into a tokenized game asset; record, on a distributed blockchain, ownership of a beneficiary right to a share resulting from selling the game asset; responsive to a sale of the game asset, transfer the share resulting from the sale to a first beneficiary; responsive to a transfer of ownership of a particular virtual item from the first beneficiary to a second beneficiary, and responsive to a second sale of the game asset, transferring a second share resulting from the second sale to the second beneficiary in accordance with the beneficiary right.

Abstract: Technologies are shown for content distribution on a blockchain. An access request is received for digital content owned by a first entity and associated with one or more blocks of a blockchain. The access request is associated with a second entity. A current use condition associated with the second entity is verified to satisfy a use requirement conditions attribute defined by at least one of the one or more blocks of the blockchain. Responsive to verifying the current use condition satisfies the use requirement conditions attribute, the second entity is provided access to the digital content.

Abstract: Technologies are shown for controlling a transaction on a digitally stored blockchain by creating a contract data block for a transaction involving entities and by event code executed after receipt of digital signatures from the entities. A refund transaction may be digitally signed by entities and linked to the contract block within the blockchain. A payment transaction block may also be digitally signed by entities and linked to the contract block. Code authorized to execute by the blocks executes based on receipt of digital signature events.

Abstract: A file system is implemented in a system comprising an anonymous-write storage device. A request for a file system operation that comprises semantics of the file system to receiving the request is received. The file system translates the file system operation to one or more commands that effect the file system operation while maintaining consistency with operation of the anonymous-write storage device. The one or more commands comprise one or more of updating file system metadata, sending a request to the anonymous-write storage device, or receiving a response from the anonymous-write storage device. The anonymous-write storage device is configured to write data in an append-only format and determine locations of data write operations agnostic of input of a write location from the file system. Metadata is updated to indicate results of the file system operation.

Abstract: In one example, a method for writing data includes receiving a write request and performing a first type of logging process in connection with the write request, and creating a corresponding first logging record. Additionally, a second type of logging process is performed in connection with the write request, and a corresponding second logging record created, where the second type of logging process is different from the first type of logging process. Next, a determination is made, as between the two logging records, which of the logging records requires the least amount of non-volatile random access memory (NVRAM), and the logging record that requires the least amount of NVRAM is written to the NVRAM.

Abstract: Garbage collection for a log-structured file system can be offloaded from a processor to an internal controller of a storage device, such as a solid-state drive. For example, an internal controller of a storage device can determine characteristics of a log-structured file system hosted by a processor that is external to the storage device. The characteristics can indicate how data is arranged in the log-structured file system. The internal controller can then execute, based on the characteristics, a garbage collection process with respect to the data of the log-structured file system on behalf of the processor.

Abstract: A system and method are presented that utilize separate append-only arrays to track metadata and real data for a file. All modifications to the file result in metadata records being appended to the end of the metadata array. Write modification commands cause real data to be appended to the file data array. The location of real data on the file data array is identified by a record in the metadata array. Modification commands can be grouped into sets, which complete as a set. Modification sets can rely upon the completeness of prior sets. Read-like commands cause the creation of a virtual array based upon the records of the metadata array. The created virtual array has the same size as the actual file but does not contain the real data for the file. Rather, the virtual file array maps to the actual data stored in the file data array.
