Currently there is an intense discussion about personal data and ownership. Although the assumption of exposing data is inherently dangerous, the opposite may be true as well. The key question focusses more on access control to manage data exposure in order to avoid risks while still getting the benefits. Or maybe it is more about establishing broad ethical standards as data availability is neither good or bad on its own – the way it is used makes the difference.
Let’s look at some use cases which illustrate the challenge. Let’s assume you feel an unusual pressure in your chest and decide to visit a doctor. He does an electrocardiogram (ECG) which looks normal. What does this mean – although it maybe normal in relation to a statistical sample but may be very unusual for you. The doctor does not have the necessary data to determine this.
Let’s assume now that you have a wearable which collects data of key body functions on an ongoing base. Many others do this as well and the gathered data can be analysed leading to algorithms which can detect anomalies like an indication of an increased risk of a heart attack on a personal level. Your data is now used in two ways – to build up the algorithm and to detect health issues for you. Please note that just doing some data gathering when you feel bad has not the same effect. The power comes from the availability of longer term data.
Let’s now assume that the new way to identify potential heart attacks reduces the perspective costs substantially. Especially in the long-term, trends and indicators can be used to influence the behavior e.g. towards more physical activity.
The data gathered could also be used to derive further information which could be used for unethical purposes.
You might say that it is always possible to switch data gathering on and off – depending on the type of data such ‘white spots’ may finally be problematic and will not help to better protect privacy. If gathering data is the norm, then switching it off could easily seen as an indicator that somebody tries to hide something may actually attract attention.
Such data could be pseudonomized – but needs to have some sort of tag to allow correlations to power the analytics or it may even by identifying itself like the ECG which is also being used for authentication.
There are many such examples – if you share your GPS position, somebody may take advantage that you are far away from home or use the data to rescue you after an accident.
I think that collecting data will be the norm. Protecting data will be key – but even more important is the need to establish ethical standards on how to deal with such data and information derived from it.
Financial newspaper “Finanz and Witschaft” published an article titled “SNB will keinen Krypto-Franken” reflecting on the speech “The financial markets in changing times – Changes today and tomorrow: the digital future” by Andréa M. Maechler, Member of the Governing Board of the Swiss National Bank (SNB) held at Money Market Event in Zurich on 05th of April 2018.
There are various views on the nature and definition of money, currency and cash which has substantially changed over time. The post How to explain ‘new’ things like bitcoin … provides some thoughts on this topic. It is very difficult to talk about all these terms as the definitions incorporate specific perspectives.
The challenge all countries, including Switzerland, face is to sustain global competitiveness. How does one move from the current economic system, of the industrial age, to one which is digital in its core. The post “Crypto Franc” – key ingredient for a Swiss national blockchain” provides a proposal published by the Fintech Rockers.
This essay proposes to create a Swiss national blockchain. A blockchain allows to track and change ownership of digital assets without the need of a central authority or intermediate. The exchange is peer to peer and cryptographically secured. Money is a key ingredient when values are exchanged and hence a blockchain infrastructure should contain some form of it to unleash the full potential.
“Such blockchain infrastructure, carried jointly by all Swiss cantons, will have an equivalent catalyst effect as the initial introduction of the railway system or the creation of the Gotthard tunnel during the age of industrialization. The Swiss national blockchain will enable local as well as foreign entities and all people with an interest and/or business relation with Switzerland to hold genuine Swiss cryptocurrency and/or execute transactions via legal compliant smart contracts.”
On this blockchain environment a cryptocurrency bound to the Swiss franc controlled by the SNB is envisioned:
“The introduction of Swiss cryptocurrency “Crypto Franc”, bound to the issued fiat Swiss Franc by the Swiss National Bank (SNB), revolutionizing digital payment capabilities. The national blockchain will enable and bring the Swiss industry(s) to the international forefront of the digital age.”
In her speech, Andréa M. Maechler commented on aspects of the proposal:
“A more prominent role for central banks in this end-customer business area is currently a subject of debate, amid calls for ‘digital central bank money for the general public’. The SNB opposes this idea. Digital central bank money for the general public is not necessary to ensure an efficient system for cashless payments. It would deliver few advantages, but would give rise to incalculable risks with regard to financial stability.”
“Which technologies and solutions ultimately prevail on this solid foundation should in principle be left to the market to decide, however. This division of roles between central banks and commercial banks epitomises our current two-tier financial system. It contributes to the stability of the system, while allowing sufficient leeway for innovation.”
Both are for sure valid points – but again perspective matters. If a “Crypto Franc” is seen as a modern form of cash then not a lot would really change. The SNB controls the amount of cash in circulation and it would continue to control the amount of cryptographic cash which could be safely kept and exchanged using a blockchain infrastructure.
Introducing cryptographic cash could have an impact on the financial system as it would allow people to keep their cash safe – within your e-wallet on a blockchain instead of your existing cash account in the bank. With a cash account the client gets a repayment promise by the bank in turn the bank can use the amount from this account for other business (e.g. mainly lending). The value of the repayment promise depends on the trust in the bank while the trust in the Crypto Franc depends on the trust into the currency.
Thus issuing cryptographic cash is not of the interest of the bank when ownership and value is no longer with the bank but with the individuals. Regardless if a cryptographic currency is introduced, the prevalent systemic risk will continue as long as there is still book money or money created though credit. As the adoption of cryptographic currency increases, it will eventually reduce the systemic risks as commercial banks need to compete for such currency of clients. Clients will need to make an explicit decision when putting Crypto Francs onto an account which means transferring ownership to the bank against a repayment promise. They need to assess the risk(s) whether a bank is able to meet its repayment promise. On the other side the bank can provide return on investment where such transparency would rather de-risk the system invalidating some of the arguments stated by the SNB.
There is an increasing interest by companies and other organizations to create their own form of money. Dr. Edward De Bono suggested years back that companies should consider to issue their own currency using IBM as the example (Towards a digital barter economy?). It was futuristic at the time where he made this proposal – but today in a digital world it becomes feasible (David Birch – Before Babylon, Beyond Bitcon – from Money that We understand to Money that understand Us ). There seems to be a trend going into this direction which could accelerate with potential huge implications on the existent monetary system.
“The SNB will keep a close watch on developments to ensure that it always remains able to assess their potential impact on the financial system in good time.”
This sounds given the context to passive. The SNB needs to active in the developments to gain the required experience. Observers will typically be late. Being late means becoming defensive and reactive. The SNB in my view should be active and engaged in building the best possible future for Switzerland and its financial system.
The ‘No’ by the SNB feels premature influenced by past paradigm rather than by the current developments and the needs of the future. One aspect became prevalent from all the statements across the various parties engaged in the thought exchange is the complexity of the topic. It is a complex network problem and requires much more thoughts and discussions. It is key to have these exchanges in a frequent but immediate manner in order to come to conclusions before other organizations/entity(s) may take over and suddenly provide “the” new form of money pushing organizations like the SNB into a reactive rather than proactive position.
Services offered by banks are mainly commodities sold with rather opaque pricing strategy. Client experience has become the main differentiator as underlying services are largely the same. The challenge has become creating outcomes which integrate into the life of the customer via respective touchpoints of the client’s eco system. This becomes difficult as the number of potential touchpoints increases significantly (ubiquitous computing).
The focus within banks has moved from operations and backend infrastructure to the touchpoints. Such focus leads to the shift in investments – which leave the backends under-invested hidden from the user by layers of newer systems. This trend started years back when the financial services industry realized that the internet is not a transient effect and changed the way business is fundamentally done. The adoption accelerated with the rise of mobile and the next catalyst with the increase usage of conversational technologies like chat or voice.
Adding more layers does not improve the overall system – instead only to delay and cover up the increasing issues and complexities of the fragile legacy backend which can no longer be sustainable (Measuring complexity in networks). From an opertional perspective the whole architecture becomes more and more unmanagable and risky highlighting the need for a substantial refactoring or more likely a total re-architecting.
Let’s for the moment assume that you own such a “backend” which becomes increasingly hard to change and difficult to operate. What could be a way out of this situation?
Be bold and start greenfield. This allows to get rid of the layers of legacy and build a system which matches current needs.
Try to be clever and refactor the system in an incremental approach. You have to be faster then the changes in the environment as you have to catch up and eliminate debts while adding the functions required to stay competitive. Implementation risk and sunk cost avoidance are the typical arguments backing this option.
Most organizations will go for the second option and try hard. They neither have strong leadership and capability(s) to aim for the first option nor the skills to actually build something new based on current state practices. The organization and the management are only trained to do small changes and the “internal immune system” reacts immediatly against any major change which could endanger the status quo.
Maybe it is better to start with a canary banking approach – where the next version of the bank is built up while the first is operational.
- One extreme is to have all functions in a single block – we have now a complicated block which hides all interdependencies between functions from the outside world.
- The other extreme is to have a block for each function and then connect the blocks based on the functional dependencies. Now each block is simple but all interdependencies have been externalized which makes the network complicated.
- If we have 4 functions in a block and add another to it, then the solution complexity of this block doubles.
- If we add an additional connection to 4 existing connections between blocks, the complexity of the network doubles.
