If the recent software failures in the financial industry are anything to go by, then disruption to payment systems are becoming the ‘new normal’. This week David O Riordan, Principal Technical Engineer, SQS Group, delves into the benefits of blockchain, in particular in the aftermath of a software disaster.
The VISA card payment outages, Faster Payments issues and disruption to card payments at BP petrol garages, all within the first half of 2018, have caused many to question the regulatory environment around financial institutions. And with the Bank of England and FCA requesting banks to report on how prepared they are for IT meltdowns, stating that any outages should be limited to just 48 hours, the finance industry is under real scrutiny when it comes to technology.
Corporations are now expected to have a Disaster Recovery (DR) and business continuity plan put into place to avoid falling victim to software failures. Nevertheless, what business leaders need to understand is that while no IT solution is completely foolproof, and will likely go down from time to time, the key is knowing how a potential internal failure can be mitigated without affecting the overall performance. This can only be achieved with a well-practiced DR plan that is second nature to the responsible parties and can be executed in the desired timeline. However, this can be both costly and time-consuming to set up. How can such incidents be minimised, or potentially eliminated, in the future? Blockchain is an alternative technology solution business leaders should consider, as it has fraud protection already built-in and is highly resistant to all type of attacks and failures.
Blockchain for Business Continuity
Built-in Fraud Protection:
Blockchain is a de-centralised platform, where every node in the network works in concert to administer the network and no single node can be compromised to bring down the entire system. It is a form of distributed ledger where each participant maintains, calculates and updates new entries into the database. All nodes work together to ensure they are all coming to the same conclusions, providing in-built security for the network.
Most centralised databases keep information that is up-to-date at a particular moment. Whereas blockchain databases can keep information that is relevant now, but also all the historical information that has come before. But it is the expense required to compromise or change these databases that have led people to call a blockchain database undisputable. It is also where one can start to see the evolution of the database into a system of record. In the case of VISA and other payment systems, this can be used as an audit trail to track the state of transactions at all stages.
Ingrained Resiliency:
Additionally, blockchain removes the need for a centralised infrastructure as the distributed ledger automatically synchronises and runs across all nodes in the network by design. As a result, Disaster Recovery (DR) is essentially built in, eliminating the need for a synchronised DR plan. The inability to alter entries in the ledger also contributes to the overall security of the blockchain, improving resilience against malicious attacks.
This is unlike traditional large centralised systems where resilience is provided by failover within a cluster, as well as site-to-site Disaster Recovery at a higher level. Disaster Recovery plans and procedures can be costly due to a large amount of hardware and data replication required. Furthermore, most businesses often do not execute it, so when disaster strikes, corporations are not prepared to deal with the aftermath; as seen with VISAs outage problems.
The Downside of Decentralised Blockchain Technology
Performance:
While blockchain can be used as a system of record, and are ideal as transaction platforms, they are slow compared to traditional database systems. The distributed networks employed in blockchain technology means they do not share and compound processing power like traditional centralised systems. Alternatively, they each independently service the network; then compare the results of their work with the rest of the network until there is an agreement that an event has happened.
Confidentiality:
In its default, blockchain is an open database. Anyone can write a new block into the chain and anyone can read it. Private blockchains, hybrid limited-access blockchains, or ‘consortium’ blockchains, can all be created, so that only those with the appropriate access can write or read them. If confidentiality is the only goal then blockchain databases offer no benefit over traditional centralised databases. Securing information on a blockchain network requires a lot of cryptography and a related computational liability for all the nodes in the network. A traditional database avoids such overhead and can be implemented ‘offline’ to make it even more secure.
Blockchain for Disaster-Relief?
As an emerging digital disruptor technology, no one can say for sure where blockchain technology will ultimately lead. While many have disregarded this technology, the potential is certainly there to attempt to solve some of the most common problems in the digital space.
However, with high customer demands on the increase within financial services and with the combination of a widespread network and substantial cost pressures, IT outages will continue to impact consumer experience. Businesses can minimise potential damage by managing communication effectively and dealing with the technical nature of the outage quickly. With a comprehensive and well-rehearsed data recovery plan, it can not only mitigate outages but maintain standards of service too. This will encourage customer retention, loyalty and growth. Therefore, blockchain should be considered, as it has a built-in check and balance to ensure a set of colluding computers can’t ‘game’ the system; as the network is virtually impossible to crack. As blockchain processing efficiency improves, it will increasingly become a more viable proposition, potentially making traditional disaster recovery unnecessary in the future.
Following the recent disasters that hit the US mainland, Finance Monthly reached out to Nalanda Matia, Lead Economist at Dun & Bradstreet, to gather thoughts on the overall impact felt by supply chains throughout the various industries, regions and markets.
Mother Nature hasn’t been kind to the United States in the past month or so; Hurricane Harvey left a trail of destruction on several counties in Texas, while Hurricane Irma devastated parts of the Sunshine State, most notably The Keys. The stormy season doesn’t look like it will abate anytime soon. The market impacts of these natural disasters are significant, particularly on densely populated and urban cities.
While the financial repercussions of Irma are still being counted, let’s take a closer look at the impact of Harvey, including affected industries, the supply chain and the future outlook of the affected areas.
Impacted industries
Early estimates have placed the impact of Category 4 Hurricane Harvey at around $75 billion, with losses from insured and uninsured residential and commercial properties making up the majority. With the addition of other costs associated with business interruptions, lapses in employment gains, and additional flooding or damage to contents of the properties, the toll could be much higher.
The top industries in the state with the largest number of jobs that have been potentially impacted by the hurricane are services; manufacturing; wholesale and retail trade; mining; construction; finance, insurance, & real estate and agriculture, forestry & fishing.
Supply chain concerns
The disruption in energy exports and other supply chain activities as ports in the state remained closed to vessel traffic until floodwater damage was assessed affected consumers and trade, creating build-ups and delays.
Many industry supply chains will take a hit as the transportation industry looks to get business back to normal. The Houston area in particular accommodates several major airports with flights to more than 70 international destinations. With some of these airports closed for a few days, the air transportation sector faced considerable backlog that they’re still coping with today.
Waterborne transportation is also in crisis due to the closure for several days of all major ports in the Houston and Corpus Christi areas. Large container ships headed to Houston to load cargo were stranded or diverted to nearby ports to wait out the storm and port closures. This caused severe supply chain disruptions in both parts of the United States and internationally. Based on the diverse nature of cargo that goes through the Houston area ports, the supply chain interruptions were not just limited to energy or chemicals, but extended to other commodities, such as agricultural products.
Business and economic impact
The parts of the United States affected by Hurricane Harvey have relatively high populations and are economically developed areas, which has contributed to high economic losses, perhaps one of the highest economic costs incurred due to a natural disaster in the US. With thousands of businesses and their employees stricken, the economic outlook for the region as a whole is expected to be lacklustre, but this prognosis may be true only in the short term.
Looking more closely at what businesses were affected, the vast majority were micro and small businesses with fewer than 10 and fewer than 100 employees, respectively. Also, close to 40% of the affected businesses are fairly young – within the first five years of their life cycles.
According to our estimates, the county of Harris, TX seems to have undergone the maximum disruption as far as the number of affected businesses are concerned. The county contains more than 60% of the businesses that have been declared at risk.
What to expect from Irma
While Irma seems to have been a slightly stronger storm in terms of wind, its financial impacts – without diminishing its severity – might be slightly less than Hurricane Harvey’s. Dun & Bradstreet estimates over two million businesses to have been in the monster hurricane’s path. This includes 49 counties in FL, three in Georgia, four in PR and two in Virginia that have been declared as disaster regions by FEMA.
Early estimates regarding these businesses are that nearly 60% of the jobs affected are in Services and Retail – with the affected regions in scenic and tourist-frequented areas. Pre-Irma, about 12% of the businesses located in the path of the storm were in the riskiest class of the Dun & Bradstreet Delinquency Predictor score. Because of the hurricane, these businesses, which were already at risk of becoming severely delinquent, will have an increasingly difficult time meeting their obligations.
Early estimates put the damage from Hurricane Irma in Florida and the surrounding areas at closer to $50bn, but the exact number is hard to predict exactly at this stage. As the southern coastal states count the cost of these disasters, we envisage a number of months until all services, transportation systems, supply chains and the economy are back to normal.
Although these current disasters are not expected to leave a permanent imprint on the economy of the United States, the immediate consequences of these increasingly frequent events cannot be ignored.
Among the thousands of individuals, charities and businesses’ making donations towards hurricane Harvey relief, and in the wake of another pending hurricane in the Caribbean, KPMG has teamed with brand ambassador Stacy Lewis this weekend to make a combined donation of $390,000 to support Hurricane Harvey relief efforts. This follows Lewis' win at the Cambia Portland Classic where she donated 100% of her tournament winnings.
Stacy Lewis was raised and currently resides in the Houston, TX area and Lewis' husband, Gerrod Chadwell, is Head Golf Coach for the University of Houston Women's Golf Team. Stacy dedicated her play on this week's LPGA Tour tournament to relief efforts, which KPMG matched. Asked what the week has taught her, Stacy reflected: "Being more appreciative. It definitely puts things into perspective."
This win marks Stacy's 12th on the LPGA Tour and first victory since 2014. In addition to KPMG's donation to relief efforts, each time a KPMG Brand Ambassador wins on Tour, KPMG makes a donation of books and refurbishes a local library as part of KPMG's Family for Literacy (KFFL) initiative. To honor this special win by Stacy, KPMG will double the typical donation with 10,000 new books to be provided to children and local KPMG volunteers will refurbish two libraries in the Houston area.
KPMG US Chairman and CEO Lynne Doughtie said: "In times like this, coming together to support one another matters the most. We are touched by the generosity displayed by Stacy, and so many across the country, to help those impacted by Hurricane Harvey."
In addition, KPMG has pledged to match partner and employee contributions up to $400,000 to the KPMG Disaster Relief Fund to provide Hurricane Harvey relief.
