Abstract: A computing system includes: server; client; broker-dealer database(s) storing personally identifiable information for accounts; and distributed ledger. Server receives request to obtain the personally identifiable information (PII) regarding public information for first account from first user of client. Server determines that a database of the database(s) includes the PII for the first account. Server determines whether the first user has permission to obtain the PII for the first account from the database that includes the PII for the first account. Server receives public information for the first account from distributed ledger when the first user has permission to obtain the PII for the first account from the database that includes the PII for the first account. Server provides the PII regarding the public information to the first user of the client.

Abstract: A computing system includes: server; client; broker-dealer database(s) storing personally identifiable information for accounts; and distributed ledger. Server receives request to obtain personally identifiable information (PII) regarding a trading history for a first account from a first user of the client. Server determines which broker-dealer database of the broker-dealer database(s) includes the PII for the first account. Server determines whether the first user has permission to obtain the PII for the first account. Server receives a trading history for the first account from a distributed ledger when the first user has permission to obtain the PII for the first account. Server is configured to map the PII from the broker-dealer database with the public transaction information received from the at least one distributed ledger to generate mapped information.

Abstract: A system, includes at least one processor; and at least one memory communicatively coupled to the at least one processor. The at least one processor is configured to receive an order to execute a trade of at least one transactional item associated with a first account, wherein the order, the first account, and a second account are associated with a common identifier; generate a first transaction to transfer the at least one transactional item from the first account to the second account; generate a second transaction that includes the order; verify that the first transaction was authorized by a same party as the second transaction; and authorize placement of the order on an exchange if the first transaction was authorized by the same party as the second transaction.

Abstract: Methods and systems described herein create a first addressed account and a second addressed account that each have a common identifier and are each associated with a customer. The system can receive an order for exchanging digital transactional items associated with the first addressed account, where the order is associated with the common identifier. A private key associated with the first addressed account can be used to electronically sign a first transaction to transfer the digital transactional items from the first addressed account to the second addressed account, and the same private key can be used to sign a second transaction. After verifying that the first transaction was signed with the same private key as the first transaction, the system authorizes placement of the order on a cryptographic exchange.

Abstract: Methods and systems described herein prevent traders from using order intent and hardware solutions to advance their order position by obfuscating the order until execution and by using a digital ledger to assign priority of the orders. As described herein, using a series of cryptographic key pairs, one side of a transaction can be created, matched, and executed while a public record is recorded and maintained but obfuscated (i.e., not publicly transparent) until after the transaction is completed.
