In Blockchain each transaction and its record is easily traceable with prevention of double spending, fraud, abuse, and any other type of manipulation.
In short, loyalty programs stored in blockchain are not only tougher to hack, but also have the ability to provide security on multiple levels that were not possible before. All points are tokenized, and that gives them unique identities that are extremely difficult to counterfeit.
It's not possible to access or corrupt information recorded in the Blockchain, since all the transaction history is stored equally on thousands of machines spread all over the world.
Scaling and handling of thousands of loyalty rewards transactions - that's what LoyalGarden is.
