Facebook’s David Marcus Advocates for Blockchain-Based Payment Networks

David Marcus, the head of Calibra at Facebook, has set forth arguments in favor of blockchain-based payment networks.

In a Sept. 25 blog post, Marcus pointed out shortcomings of existing payment systems such as regional and international networks, including SWIFT and RT1, central banks and others. Marcus began by noting the weakness of the underlying infrastructure of the current system that limits its efficiency and reach.

In one case, Marcus wrote, an individual can send and receive funds from within one wallet, while not being able to do the same between wallets from different companies. He went on to explain:

“Depending on the setup, moving money from point A to point B requires a number of intermediaries to be involved, and often demands liquidity pools to be readily available at point B for consumers to get their money out in a timely fashion.”

Advantages of blockchain payment networks

When it comes to a blockchain-based payment network like Facebook’s forthcoming Libra, its participants can purportedly carry out near real-time cross-border transfers at a low cost and with no need of liquidity pools of various currencies, Marcus said, adding:

“This would in turn massively reduce costs by eliminating the need for so many intermediaries, and operational complexity and overhead, thus increasing innovation and access. People would benefit from more ease when they want to send and receive money, and the barrier of access to modern digital money and financial services would be greatly lowered.”
