Bitcoin has received all kinds of press, from the apocalyptic to the sycophantic. Meanwhile its underlying blockchain technology has stealthily become an intense focus of research by the banking community. Could this technology and mechanisms like it become an integral element in the future machinery of finance? What are the implications for ordinary citizens?
Last October 2015, The Economist published a briefing on blockchain technology explaining how it works and what it implies – one of the most fascinating articles I read that year. After reading, I felt that blockchains had the potential to change the 21st century more than credit cards, ATMs, and mutual funds changed the 20th.
I’ve annotated the article with Hypothes.is. To read my annotations within the article you’ll need to join (for free) which I highly recommend and will discuss in another post at some point.
For the article, see The Economist, Oct 31st, 2015, The great chain of being sure about things.
In case you don’t wish to join Hypothes.is, I’ve included my annotations here.
This has implications far beyond the cryptocurrency
The concept of trust underlies exchange. During the 15th-17th centuries, the Dutch and English dominance of trade owed much to their early development of instruments of credit that allowed merchants to fund and later to insure commercial shipping without the exchange of hard currency, either silver or by physically transporting the currency of the realm. Credit worked because the English and Dutch economies trusted the issuers of credit.
Francis Fukuyama, a philosopher and political economist at Stanford, wrote a book in 1995, Trust: The Social Virtues and the Creation of Prosperity, on the impact of cultures of trust on entrepreneurial growth. Countries of ‘low trust’ have close family culture who limit trust to relations: France, China, southern Italy. Countries of ‘high trust’ have greater ‘spontaneous sociability’ that encourages the formation of intermediate institutions between the state and the family, that encourage greater entrepreneurial growth: Germany, England, the U.S. (I own a copy of Trust and haven’t yet read it – shame on me!)
I thought of this article on Bitcoin in that context – of the general need for trusted institutions and the power they have in mediating an economy, and the fascinating questions raised when an entirely new method of trust is introduced to society.
Trust is integral to human association and the concentric circles of society: family, ethnicity, neighborhoods, city, and state. How do we ensure trust within and across those circles? Throughout human history, how have we extended the social role of trust to state institutions? If a new modality of trust comes available, how does that change institutional structures and correspondingly the power of individuals and of institutions. How would it change the friction to growth and to decline?
Prior to reading this article, I had dismissed Bitcoin as a temporary aberration, mostly for criminal enterprises and malcontents. I still feel that way. But the underlying technology and it’s implications – now that’s interesting.
It is the third bucket that contains the most ambitious applications: “smart contracts” that execute themselves automatically under the right circumstances. Bitcoin can be “programmed” so that it only becomes available under certain conditions.
In other words, blockchain technology can facilitate a deferred payment system that works when the payer provides payment in escrow. Like Kickstarter and other crowdfunding systems. It could manage deposits on purchase-and-sale agreements and handle escrows on legal judgments without a third party holding title to the money. The core financial system itself would ‘hold’ the money by ensuring no transaction took place against the payer’s funds that would make the future payment impossible.
Note that ensuring the ability to pay can be the simple calculation of ensuring liquid assets never fall below the owed amount or it could be complex, taking guaranteed future cash flow into account. The latter is the kind of calculation a sophisticated blockchain system might be able to make if it held those guarantees of future cash flow.
Could a blockchain financial system be made into a complete deferred payment system for managing loans, mortgages, and coupon bonds? I don’t know how, since the source of those payments is outside the bitcoin system and generally doesn’t exist at the time of the loan or bond purchase. But imagine if a financial system was entirely built around a programmable trust system, then financial instruments themselves become a part of the logic of a company’s assets and liabilities. When a corporate bond coupon comes due, the company treasurer doesn’t create a transaction, instead the coupon payment is automatically transferred to the holder of the bond by the financial system itself. That is, the structure of the bond would be integrated, that is, coded directly into the financial system for automatic execution.
If a future government were to implement blockchain technology and legislate its adoption throughout the financial community (perhaps as an option, in parallel with the preexisting system), it could ‘write the code’ for legally certified instruments like stocks, corporate bonds, mortgages, car loans. It could further write legally permissible derivatives of those instruments (yes, derivatives have tremendous value in reducing risk when used wisely).
At that point, financial companies like Vanguard or Fidelity could issue mutual funds whose prospectuses assert that the only kind of instruments held by the fund were those certified by the government to use the legislated systems. This could reasonably allow safe and less expensive adoption of powerful financial instruments with far less risk to the system.
Sure there are plenty of flaws and dangers in this kind of a system and its complexity may be beyond what our current computer technologies can reliably secure. But could this eventually be worked out to create a safer, less expensive, more transparent and more accessible financial system than we currently have? Would it help engender some of the trust that our financial titans have lost time and again? There are enormous benefits to society if it can.
