Multi-tenant node on a private network of distributed, auditable, and immutable databases

A computing device comprising:

• one or more processors;
• and
• memory storing instructions that, when executed by the one or more processors, cause the computing device to:
• receive a record, wherein the record comprises a transaction identifier and identification information for each of one or more approving devices;
• generate a temporary record based on the record;
• generate, based on the record, a first verification parameter for each of the one or more approving devices, wherein the first verification parameter comprises a result of a first one-way function applied to:
• a unique code associated with one of the one or more approving devices, an identifier associated with the one of the one or more approving devices, an asset identifier, or a record identifier;
• and
• generate, based on the record, a second verification parameter for each of the one or more approving devices, wherein the second verification parameter comprises a result of a second one-way function applied to the transaction identifier and the identifier associated with the one of the one or more approving devices;
• send, to a device associated with each of the one or more approving devices, the temporary record, the first verification parameter, and the second verification parameter;
• receive, from a quantity of the one or more approving devices, one or more messages, wherein each of the one or more messages comprises an indication of a veracity of the temporary record;
• generate, based on a determination that the quantity satisfies a threshold, a signature associated with the record;
• store the record in a ledger;
• and
• delete, after the storing the record in the ledger, the temporary record.

A non-transitory computer readable medium storing instructions that, when executed, cause:

• receiving a record, wherein the record comprises a transaction identifier and identification information for each of one or more approving devices;
• generating a temporary record based on the record;
• generating, based on the record, a first verification parameter for each of the one or more approving devices, wherein the first verification parameter comprises a result of a first one-way function applied to:
• a unique code associated with one of the one or more approving devices, an identifier associated with the one of the one or more approving devices, and an asset identifier;
• and
• generating, based on the record, a second verification parameter for each of the one or more approving devices, wherein the second verification parameter comprises a result of a second one-way function applied to the transaction identifier and the identifier associated with the one of the one or more approving devices;
• sending, to a device associated with each of the one or more approving devices, the temporary record, the first verification parameter, and the second verification parameter;
• receiving, from a quantity of the one or more approving devices, one or more messages, wherein each of the one or more messages comprises an indication of a veracity of the temporary record;
• generating, based on a determination that the quantity satisfies a threshold, a signature associated with the record;
• storing the record in a ledger;
• and
• deleting, after the storing the record in the ledger, the temporary record.
