Mastercard has reportedly registered a system that can generate blocks for a partitioned blockchain with the US Patent and Trademark Office, following the patent application filed back in July 2016.
As the US Patent and Trademark Office stated, it is quite hard now to keep different data about transactions on the platform using only one blockchain. In this situation, Mastercard developed a system that can create blocks for permission blockchain to store different information.
"However, the transaction records stored in the blocks comprising a blockchain are often required to be of the same format and include the same types, and sometimes even sizes, of data. In the case of an entity that wants to use multiple types of blockchains, such as a different blockchain for several different currencies, the entity must deploy and operate each of the different blockchains, which may require significant resources and processing power," the document reads.
The Mastercard team said that the market requires so-called sectioned blockchain or in other words, the way to store transaction data of different formats and types in one distributed register. As a result, each section called sub-network will hold information about one currency or just data that differs from that in other sub-networks.
It is worth mentioning that Mastercard has collected the largest number of patents in terms of blockchain application.
