摘要： A method executed by a computing device includes determining whether baseline content associated with a longevity-contingent instrument is qualified for a proposed a non-fungible token (NFT) for an object distributed ledger. The baseline content includes an obligation provider identifier (ID) and an outcome recipient ID. When the baseline content is qualified, the method further includes determining an exposure level for the NFT and establishing NFT content. The method further includes causing generation of a new block affiliated with the NFT via a blockchain of the object distributed ledger, where the new block includes the NFT content.

摘要： Provided are a data storage method, a device, and a storage medium. The implementation scheme is as follows: target data to be stored is divided into data fragment original texts, and storage nodes are allocated for the data fragment original texts; in a trusted execution environment, the data fragment original texts are encrypted according to node information of the storage nodes to obtain data fragment cipher texts associated with the storage nodes; and the data fragment cipher texts are stored to the storage nodes.

摘要： A method and system for creating and managing secure tokens associated with users and assets. The method and system of the present invention provide mechanism for dynamically associating a token with one or more users as owners and one or more assets to track the changes in value of those assets. The monetary value of token is determined using a functional relationship with associated assets. The token can be monetized by users associated with the token as owners in the proportion of their ownership. Monetization of the token represents processing of payments equivalent to the monetary value of the token at the time of monetization.

摘要： A method is described. The method can include establishing a block chain network of multiple imaging devices. The block chain network can be established such that, at least a first imaging device of the multiple imaging devices can be validated by at least a second imaging device of the multiple imaging devices. Further, the method can include generating a block message by the first imaging device. The block message can be generated by using a secured hash function and based on a set of parameters that can be associated with the first imaging device. The set of parameters can include, a first imaging device identifier, a network fluctuation parameter, and at least one inertial parameter. Furthermore, the method can include sending by the first imaging device the block message to the second imaging device. In this regard, the block message can facilitate validation of the first imaging device.

摘要： The present invention discloses a system and method of trading registered equities with the Securities and Exchange Commission on an immutable blockchain on an immutable blockchain, while also integrating with the rules and regulations of the existing brokerage ecosystem. In these systems and methods, customers are invited by at least one broker dealer to participate as a user on the digital trading platform to take a cash immutable action that comprises the placement of at least one of an order, bid or offer. The action, containing a digital price, is then entered into the digital trading platform, stored on the platform and used to facilitate a spot market transaction between a buyer and a seller.

摘要： A first hash of a record is retrieved. The first hash is tokenized by storing the first hash in a tokenization table that has a corresponding hash token. A request is received to validate the record. The request to validate the record comprises a second hash of the record and a second hash token. In response to receiving the request to validate the record, the record is validated by looking up the first hash in the tokenization table using the second hash token and comparing the looked up first hash to the second hash. In response to the looked up first hash being the same as the second hash, the record is validated. In response to the looked up first hash not being the same as the second hash, the record is not validated.

摘要： A first hash of a record is retrieved. The first hash is encrypted using an encryption key to produce an encrypted hash. The encrypted hash is stored in the record by replacing the first hash with the encrypted hash or by adding the encrypted hash to the record. A request is received to validate the record. In response to receiving the request to validate the record, the record is validated by: unencrypting the encrypted hash using the encryption key to produce a second hash; hashing the record to produce a third hash; and comparing the second hash to the third hash. In response to the second hash being the same as the third hash, the record is validated. In response to the second hash not being the same as the third hash, the record is not validated.

摘要： A device includes: a storage storing a distributed ledger, the distributed ledger including a plurality of evidence chains and a time stamp chain, the plurality of evidence chains storing in chronological order at least one hash value, the time stamp chain storing in chronological order at least one time stamp token; and a processor configured to repeatedly execute an update process such that the time stamp chain is updated, the update process including a process for identifying, out of the evidence chains, at least one evidence chain in which the hash value has been changed with a change in the file since previous execution of the update process, and acquiring the time stamp token for a terminal value generated based on a terminal hash value of the at least one evidence chain.

摘要： A technique for controlling participation of a miner in a computation of a block for a message to be added to a blockchain in a blockchain network is disclosed. The miner is configured to perform block computation for messages of one or more security levels available in the blockchain network. A method implementation of the technique is performed by the miner and comprises receiving (S308) the message, checking (S310) whether a security level indication associated with the message matches one of the one or more security levels configured for the miner to determine whether the miner is to participate in the computation of the block for the message, and starting (S312) to compute the block for the message if it is determined that the miner is to participate in the computation of the block for the message.
