The Alpha Audit tool is a simple, secure, transparent and cheap way of creating a tamper-proof audit trail for internal processes and documents. At Araneum Technologies the Alpha Audit is part of our Trading Engine and ensures the creation of a transparent audit trail and track-record by logging all trades and signals from our Signaling & Trading Engine with a smart contract on the Ethereum blockchain. The trade entry is done via a web-interface, where all the necessary information gets encrypted (“hashed”). After creating a unique hash-key, the user can log the trade or information on the Ethereum Blockchain trough our web-interface, where automatically an entry in the blockchain is created with the hash-key and a timestamp. The logging of the hash-key ensures the highest data security for sensitive and non-public information as only the hash-key and timestamp can be accessed publicly on the blockchain. Finally, each trade gets displayed in the Alpha Audit dashboard and can be cross-validated by any third-party by comparing the hash-keys and timestamps generated in the web-interface and the hash-key and timestamps logged on the blockchain. Alpha Audit is available to the public as a stand-alone service.
