A balance and control system may write a data file transfer confirmation from a transmitter system to a blockchain in response to the transmitter system transmitting a data file to a receiver system with the confirmation including a transmitter system address, a receiver system address, and a first hash of the data file. The system may also write a data file transfer acknowledgement from a receiver system to the blockchain with the acknowledgement including the transmitter system address, the receiver system address, and a second hash of the data file. The blockchain may execute a smart contract to compare the first hash of the data file to the second hash of the data file to identify an out-of-balance file transfer event. A monitoring device of the B&C system may read the out-of-balance file transfer event from the blockchain.

Systems and methods for data file transfer balancing and control on blockchain

A balancing and control (B&C) system for API transactions is disclosed. The system may write a request confirmation and a request acknowledgement to a blockchain in response to an API request being transmitted from a consumer system to a provider system, with the request confirmation and the request acknowledgement each comprising a request hash of the API request. The system may also write a response confirmation and a response acknowledgement to the blockchain in response to an API response being transmitted from the provider system to the consumer system, with the response confirmation and the response acknowledgement each comprising a response hash of the API response. The blockchain may execute a smart contract to compare the request hashes from the request confirmation and the request acknowledgement and the response hashes from the response confirmation and the response acknowledgement to identify one or more out-of-balance events.

API request and response balancing and control on blockchain

A messaging balancing and control (B&C) system is disclosed. The system configured to handle message transfers having different message exchange patterns, including: in-only exchange patterns, out-only exchange patterns, in-optional-out exchange patterns, out-optional-in exchange patterns, robust in-only exchange patterns, and robust out-only exchange patterns. The system may write a message transfer confirmation in response to a message transfer between a consumer system and a provider system, with the confirmation including at least a first hash of the message. The system may also write a message acknowledgement to the blockchain with the acknowledgement including at least a second hash of the message. The blockchain may execute a smart contract to compare the first hash of the message to the second hash of the message to identify an out-of-balance message transfer event. A monitoring device of the system may read the out-of-balance message transfer event from the blockchain.
