1. A computer-implemented method for fast decryption of one or more payloads, the method comprising the steps of: providing a frontend server operatively connected to at least one slave read-only database, the frontend server configured for receiving one or more received payloads and authenticating each of the one or more received payloads by comparing data included in the one or more received payloads with data included in the at least one slave read-only database; providing a hardware security module implemented by at least one processor, wherein the hardware security module is operatively connected to the frontend server via a hardware security module server and is for decrypting encrypted portions of the one or more received payloads; and providing a message queuing protocol implemented by at least one processor operatively connected to a read-only database and a read/write database, the message queuing protocol configured for receiving event notifications from the read-only database and transmitting the event notifications to the read/write database upon determining that the read/write database is configured to accept event notifications.
