1. A system including a first point-of-sale terminal, the system comprising:
a processor and a memory configured to store transaction data therein;
a network interface configured to connect to a computing network and configured to receive, from the computing network, a message comprising blockchain information,
the first point-of-sale terminal being configured to create transaction data for an initial block of a blockchain ledger based on a first transaction at the first point-of-sale terminal and store the transaction data in the blockchain ledger, such that, upon creation, the transaction data is stored in a local cache and then sent to the computing network, the first point-of-sale terminal being provided to service transactions at a first location of a restaurant,
the system being configured to
synchronize the transaction data between the local cache and a remote memory accessible via the computing network, wherein
the synchronized transaction data includes sales data of point-of-sale transactions conducted at a plurality of point-of-sale terminals including the first point-of-sale terminal and a second point-of-sale terminal, the second point-of-sale terminal being provided to service transactions at a second location of the restaurant, and
link transaction information of the first transaction at the first point-of-sale terminal with transaction information of a second transaction at the second point-of-sale terminal such that the blockchain ledger includes the transaction information of the first transaction and the second transaction, the second transaction being later than the first transaction, wherein
the linking of the transaction information comprises linking an order ID, which is generated when a first item is selected at the first point-of-sale terminal, with another order ID, which is generated when a second item is later selected at the second point-of-sale terminal, the first item different from the second item,
wherein the first transaction and the second transaction relate to at least one of at least one drawer session or labor activity, and the transaction data is associated with at least one of the first transaction over a time period according to the at least one drawer session or a worker identity and a time period worked according to the labor activity.
