Mastercard Files Patent for Increasing Anonymity of Blockchain Transactions

[Nikko]

Mastercard has filed a patent for a method of anonymizing transactions on a blockchain, according to an application published by the United States Patent and Trademark Office (USPTO) Dec. 9.

The filing outlines that “the use of one or more intermediary addresses to obscure the source and destination of funds in a blockchain transaction” can be used in order to “increase anonymity of entities associated with blockchain addresses.” The proposed technical solution would entail a series of “anonymization request” designed to anonymize the transactions themselves, rather than just the user behind any individual wallet.

This would “result in showing the user only transferring funds to and receiving funds from a small number of addresses that are also involved in a significantly large volume of transactions with various other users, thereby rendering the data innocuous.” Analysis of the wallet, Mastercard suggests, would thus yield “little to no information” about the user behind the wallet.

As context, Mastercard notes that while many “are flocking” to various blockchain-based cryptocurrencies, such as Bitcoin (BTC), for the perceived “high level” of anonymity they can provide, “the nature of the blockchain as an immutable ledger is such that every transaction can” - ultimately - “be traced and followed back to the genesis block.”
