Companies have played with it; they understand what blockchain does and how it works. Their innovation labs have participated in proof of concepts (POCs) and may belong to one or more industry consortiums created to vet the technology, but they haven’t taken the next step and implemented the technology for any mission critical apps.
What’s Holding Back Blockchain?
One of the fundamental issues holding blockchain or distributed ledger technology (DLT) back is the level of maturity of the technology, to wit, it’s current inability to support large-scale financial infrastructures by working in millisecond speeds. Currently the math, which is CPU-intensive can only support single digit to tens of transactions per second. It’s a bit of hurry up and wait!
The problem was highlighted in a recent article on Finextra, “Bank of Japan exec warns FS firms against leaving DLT expertise to tech providers." "There is absolutely no doubt that DLT is an unprecedented innovative technology,” said Bank of Japan executive director Shigehiro Kuwabara. “However, based on the level of its technology at this stage, it cannot be said to have yet reached the absolute superiority required to fully replace the current centralized system.”
However, consortiums like the Hyperledger are working on a new release of their open source code base that is supposed to support more than 1,000 transactions a second. What’s more, Hyperledger participant IBM’s new z Systems server platforms reportedly will be able to double that speed. Other developers like Ripple and Etherium are right behind; a lot of people are working on this.
Once the speed is there, which Oliphant thinks could be between the later half of 2017 and the first half of 2018, early adopters are expected to jump on it, followed by mass movement by the rest. “Blockchain needs to be mature first,” he said, “and we expect the rest to be fast-followers!”
ACI, which enables more than 5,000 processors and banks to transact $14 trillion daily through its suite of software-as-a-service tools, has been actively engaged with blockchain technology and POCs for the last two years. However it’s only been the last few months that its customers have started to step up to the blockchain plate.
We are just starting to see customers with requests for information (RFIs) and requests for proposals (RFPs). They want to engage with us and multiple blockchain providers. Our customers tend to have large payment infrastructures integrated to perform various payment functions and they are looking to ACI to help them integrate the technology with their existing payment systems. They want to move incrementally.
What Should Customers Do Now?
We recommend that customers identify critical business use cases where they can use the technology to bring business value and improvement to existing processes or create new products and services. A compelling use case will help drive the technology (much as Bitcoin did originally). That will also make it easier for their CIOs to fund it versus launching a blockchain initiative that is looking for a problem to solve. Customers should be laser-focused.
Fortunately, not all use cases require high velocity/high performance blockchains. That means that institutions can be supported by the technology today.
- Some of the top current use cases that do not require millisecond transaction speeds are:
- Cross-border payments
- International remittances: replacing current mechanisms to send money between family members.
- Supply chain management
- Centralized Referable Records/Data
Several blockchain providers such as Chain Inc., IBM and Ripple are beginning to offer products/services in these areas. The important thing for customers is to identify use cases that would bring business value to them. Conversely, high velocity use cases, including clearing and settlement, and stock trading, will have to wait a little longer until the technology is ready. But as discussed above, potential customers will likely not have much longer to wait.
