Systems and methods for storing and sharing transactional data using distributed computer systems

A computer system configured to communicate with a distributed blockchain computer system that includes multiple computing nodes, each computing node configured to store a copy, or a portion thereof, of a blockchain of the distributed blockchain computer system, the computer system comprising:

• a transceiver configured to receive a match message from another computer system that matches data transaction requests, the match message including match data for a match between a first data transaction request that is associated with a first identifier and a second data transaction request that is associated with a second identifier;
• a storage system configured to store a data structure for a plurality of accounts, each one of the plurality of accounts including at least a private key and a public key, the plurality of accounts including an intermediary account, where the first and second identifiers are associated, respectively, with first and second accounts of the plurality of accounts;
• a processing system that includes at least one hardware processor, the processing system configured to:
• in response to reception of the match message:
• (a) generate a first blockchain transaction that includes the match data for the match between the first data transaction request and the second data transaction request;
• (b) transmit the first blockchain transaction to the distributed blockchain computer system for storage into the blockchain;
• generate at least one further blockchain transaction that includes information for a first transaction from the first identifier to an intermediary identifier that is associated with the intermediary account and information for a second transaction from the intermediary identifier to the second identifier;
• transmit the at least one further blockchain transaction to the distributed blockchain computer system for storage into the blockchain.
