摘要： An information computer system is provided for securely releasing time-sensitive information to recipients via a blockchain. A submitter submits a document to the system and a blockchain transaction is generated and submitted to the blockchain based on the document (e.g., the document is included as part of the blockchain transaction). An editor may edit the document and an approver may approve the document for release to the recipients. Each modification and/or approval of the document is recorded as a separate transaction on the blockchain where each of the submitter, editor, approver, and recipients interact with the blockchain with corresponding unique digital identifiers—such as private keys.

摘要： A computer system is provided that communicates with a distributed blockchain computing system that includes multiple computing nodes. The exchange stores an order book and a plurality of digital wallets associated with different clients. The computer system receives new data transaction requests that are added to the order book. A match is identified between data transaction requests and hashes associated with the digital wallets associated with the respective data transaction requests are generated. The counterparties receive the hashes of the other party along with information on the match and each party causes blockchain transactions to be added to the blockchain of the blockchain computing system. The computing system then monitors the blockchain to determine if both sides of the match has been added to the blockchain.

摘要： Systems and methods are provided for recording ownership information in a distributed ledger (such as a blockchain), and for performing application processing utilizing the distributed ledger. An example server computer system is configured to: record on a blockchain ownership information of an asset; to configure, for each owner of the asset, a digital wallet associated with a private cryptographic key and at least one blockchain address; using a blockchain address from a digital wallet to access ownership information in the blockchain; perform application processing using the accessed ownership information; and record in the blockchain, updated ownership information or other information associated with the ownership information in accordance with the performed application processing.

摘要： A computer system is provided that allows participants to submit agent data structures for processing. Each agent data structure includes a valuation function for a first resource and a property of a second resource. The computer system performs a dual sided evaluation process to determine when contra-sided agents match with one another. A match is determined by comparing results of valuation functions of the agent data structures.

摘要： The described technology relates to a real-time order processing systems such as, for example, an electronic trading application for equities and other tradable investment instruments. An example system relates to reordering messages received at a server over a communication network from distributed clients, in order to, among other things, eliminate or at least substantially reduce the effects of jitter (delay variance) experienced in the network. The reordering of messages may enable the example electronic trading system to improve the consistency of executing orders (e.g., performing transactions for buying/selling electronic inventories) in the time order of when the client's order entered the trading system's network.
