Blockchain: Still in the Proof of Value Stage by Esther Pigg

business value of blockchain payments

Last May, I wrote an article entitled, “Blockchain: Mystery or Reality for the Financial Industry?” in which I described blockchain in this way:

“Imagine a spreadsheet (ledger) that is duplicated (distributed) thousands of times across a network of computers (nodes). This spreadsheet is constantly reconciled (by miners) and updated instantly with new transactions (blocks). The spreadsheets are permanent, public and verifiable (proof of work).”

Its potential is significant but the spectrum of expert opinions about its application for payments is wide:

“This technology is amazing. It is a technology of the future. It provides tremendous opportunities [but] the technology is not ready right now. When will it be ready? [In] three to five years, in my opinion.”

 Herman Gref, CEO of Russia’s Sberbank

“With multiple ledgers operating at full throttle, the associated communication volumes could bring the Internet to a halt.”

While experts continue their debate, blockchain proof of concepts are now being piloted but still in the proof of value stage. Questions to be answered include:

  • What’s the business value?
  • What problems does blockchain solve that cannot be solved with existing platforms?
  • Are its potential benefits offset by inherent flaws that make its widespread use impractical?

Touted Benefits of Blockchain Payments

The primary blockchain payment application that’s being explored is to bring efficiency to cross-border settlements for bank-to-bank payment transfers. While no one doubts the need to make cross-border payments more efficient, can blockchain solve the problem better than alternatives?

The debate about blockchain’s ability to handle the volume of cross-border payments continues. Most tests have been conducted in closed or private blockchain networks. Fragmented networks – closed or private – with different operating standards could hinder widespread usage of blockchain.

Test results so far are mixed. On one hand, a pilot by Western Union failed to provide time or dollar savings. In contrast, Ripple claims to have reduced the time it takes to effect a cross-border payment from a couple of days to a couple of minutes, at significant savings on Forex (FX) exchange rates.

The other benefit of blockchain that’s been widely touted is its potential to reduce costs by cutting out the middleman. But, as a sample of one, here’s a quick report of my personal experience:

A coworker and I downloaded a bitcoin wallet recently. My coworker deposited $40 at the closest bitcoin ATM, which happened to be at a gas station. Within 20 minutes there was, indeed, bitcoin in the crypto wallet, but only $25 – not even close to the $40 that was deposited.

Without oversight, there is no guarantee that wallet issuers and exchanges are legitimate and that wallets are secure.

Can Blockchain Overcome Its Inherent Flaws?

Blockchain’s proponents are working on solutions to compensate for some major obstacles to widespread acceptance in the payments ecosystem:

  • The inability to scale due to the complexities involved in reconciling transactions represents a major impediment. Ripple’s eCurrent solution used by Banco Santander for cross-border payments does not employ distributed ledger technology (DLT) because it lacks scalability and privacy. Red Belly Blockchain hopes to solve the scalability issue by using an alternative consensus algorithm instead of the current “proof of work” system. However, the issue around lack of privacy inherent in a public, decentralized ledger remains.
  • People conflate blockchain and its volatile cryptocurrency applications. The United States Senate Banking Committee holds the view that the potential for fraud associated with cryptocurrencies outweigh the potential benefits of blockchain. One possible solution to combat volatility are stablecoins – the most prominent holding one US dollar in a trust account for each coin issued.
  • Cross-network standards of governance for interoperability also are needed to drive scale and acceptance.

Payments Top Priorities: Ensure Safety and Security

Our current payment platforms are reliable and the digital transformation underway across the ecosystem will continue to reduce friction and costs. Still, industry leaders must continue to explore the possibilities and potential of blockchain. Ultimately, they will choose the best of distributed, permissioned and secure technology – blockchain or another utility – to clear and settle transactions globally, at scale.
