Mastercard Seeks 'Fast Track' Way to Sync Blockchain Data - CoinDesk
In a patent application published Thursday by the U.S. Patent and Trademark Office, the company outlines a method by which nodes can connect with and verify the contents of a particular blockchain. Per Mastercard, the idea is to boost the speed at which the nodes - which store a copy of that network's transaction history - can get up to date.
Mastercard first filed the application back in October 2016. And as the application explains, "a blockchain may store thousands, millions, or even billions of transaction records over time in a vast number of different blocks."
While this is part of its immutable nature, this also means the blockchain could "contain thousands, millions, or billions of blocks, each of which must be verified by the new node prior to the generation and addition of new blocks to the blockchain."
