Mastercard received a multicurrency blockchain patent
The story:
On October 9, American financial services giant Mastercard was granted a patent for a method to partition a blockchain so that it can store multiple transaction types and formats.
Details:
Modern blockchain systems retain transaction records in separate blocks that make up a chain, “often required to be of the same format and include the same types, and sometimes even sizes, of data.”
Now, imagine a company that wants to use blockchain technology to store different kinds of data or use multiple cryptocurrencies for their business. Consequently, this company will also have to be able to afford all the extra resources and computing power involved.
The patent proposes to solve the problem with the “partitioned blockchain” and describes in general terms how block generation and storage of transaction data will work in such a system. The patent introduces the term “subnet” for the proposed divisions, which will go consistently, but will interact in a wider, unified system.
Why it is important:
The American giant MasterCard is the third largest with a hefty 80 patent filings, surpassed only by Alibaba and IBM, which makes it a key participant of the potentially forthcoming patent war in the field of blockchain.
