Exit, Voice, and Forking

With Alastair Berg. Published in Cosmos + Taxis, Volume 8, Issue 8-9, 2020

Abstract: This paper offers a new framework to understand institutional change in human societies. An ‘institutional fork’ occurs when a society splits into two divergent paths with shared histories. The idea of forking comes from the open-source software community where developers are free to copy of a piece of software, alter it, and release a new version of that software. The parallel between institutional choice and software forking is made clear by the function and politics of forking in blockchain implementations. Blockchains are institutional technologies for the creation of digital economies. When blockchains fork they create two divergent communities with shared transaction ledgers (histories). The paper examines two instances of institutional forks. Australia can be seen as a successful fork of eighteenth-century Britain. The New Australia settlement in Paraguay can be seen as an unsuccessful fork of nineteenth century Australia.

Some Economic Consequences of the GDPR

With Darcy Allen, Alastair Berg, Brendan Markey-Towler, and Jason Potts. Published in Economics Bulletin, Volume 39, Issue 2, pages 785-797. Originally a Medium post.

Abstract: The EU General Data Protection Regulation (GDPR) is a wide ranging personal data protection regime of greater magnitude than any similar regulation previously in the EU, or elsewhere. In this paper, we outline how the GDPR impacts the value of data held by data collectors before proposing some potential unintended consequences. Given the distortions of the GDPR on data value, we propose that new complex financial products—essentially new data insurance markets—will emerge, potentially leading to further systematic risks. Finally we examine how market-driven solutions to the data property rights problems the GDPR seeks to solve—particularly using blockchain technology as economic infrastructure for data rights—might be less distortionary.

Blockchains and Constitutional Catallaxy

With Alastair Berg and Mikayla Novak

Abstract: The proposition that constitutional rules serve as permanent, fixed points of interaction are challenged by observations of contestable rule amendment and the emergence of de facto authority. This observation not only applies to conventional political constitutions, but to the fundamental rules which govern interactions by numerous people using new forms of technology. Blockchain technology aims to coordinate action in a world of incomplete information and opportunism, but the governance arrangements in blockchain protocols remain far from settled. Drawing upon recent theoretical developments regarding constitutional change, we interpret changes to the fundamental working rules of blockchain protocols as central to the adaptive, emergent nature of activity within this technological space. We apply this concept of “constitutional catallaxy” to selected blockchain platform case studies, illustrating the dynamism inherent in establishing protocols within the blockchain. Blockchain coordination changes and adapts not only to the technological limitations of the available protocols, but to mutual expectations and influence of interacting stakeholders.

Blockchains and constitutional catallaxy: an EOS case study

With Alastair Berg. Originally a Medium post.

The EOS mainnet launched earlier this year.

In EOS we are witnessing the emergence of what Ludwig von Mises and Friedrich Hayek would recognise as constitutional catallaxy — open source constitutional orders in which participants are continually developing the rules of the game even after the game has started.

EOS operates under a Delegated Proof of Stake (DPoS) consensus mechanism, with 21 Block Producers (BPs) overseeing the validation of transactions. As an open source constitutional order, the jurisdiction of these BPs has been guided by de jure constitutional arrangements. In the pre-launch phase of EOS, documentation was drafted and debated outlining an EOS Constitution, while users were to include a hash of that document in their transactions to acknowledge their understanding and acceptance of it.

However, open source constitutional orders like EOS also have stakeholders who may exercise de facto authority in the absence of formal procedural rules or technical constraints.

The launch of the EOS mainnet provides examples of how de jure and de facto constitutional arrangements can diverge. While no token holder vote has taken place on the EOS Constitution (via their proxies — BPs), de factosovereignty was quickly exercised through the banning of seven (and later many more) accounts following a conference call between BP representatives and a body known as the EOSIO Core Arbitration Forum (ECAF).

As a result of this call, BPs chose to exercise de facto sovereignty and freeze these accounts. Only retroactively did this dispute resolution body ECAF issue a statement which indicated their support of the actions of BPs.

Similarly, 6 weeks after launch, an announcement was made to fundamentally change the way in which economic value is distributed across the EOS protocol. On July 28 Brendan Blumer, CEO of block.one (the organisation which developed the EOS mainnet), announced changes in the way EOS inflation is to be allocated. This will see new EOS tokens being distributed to users who stake tokens and vote for BPs, in addition to the rewards BPs receive for overseeing the validation of transactions.

These actions have drawn support as well as opposition. Some have called it a successful demonstration of off-chain governance, while some see it as jurisdictional overreach by emergent institutions.

In previous articles, we have argued that blockchains are a lot like countries. These (usually) open source protocols are constitutional orders which define how individuals interact and transact — complete with their own currencies, property, laws, corporations and security systems.

Blockchains, along with nation states, attempt to coordinate action in a world of incomplete information and opportunism — while computer scientists and economists have different vocabularies, Byzantine fault tolerance and robust political economy are the same thing.

Systems of governance for blockchain protocols are not new — the genius of Satoshi Nakamoto was to allow the Bitcoin network to reach consensus when two equally valid blocks are presented by miners, in effect solving the double-spend problem.

Yet now we can observe the emergence of — and have debate over — other governance arrangements in blockchain protocols. (Who writes and has permission to change the law (code), who enforces the rules, the role and method of voting, the role of developers and token holders, on-chain and off-chain governance etc).

What’s interesting is that these are analogous to the debates that individuals had during the emergence of nations. Consider the United States. With little to guide them but the musings of philosophers and radical thinkers, individuals grappled with a myriad of competing principles and interests as they set the ground rules for how their new constitutional order was to be governed.

Previously, constitutional orders emerged from revolution, civil war, conquest and other usually violent means — much like the constitutional order that emerged in the 13 American colonies.

In the real world, the emergence of institutions — as well as the jurisdiction which they exercise power over — can take many years after their formal establishment. The Supreme Court of the Unites States has the now familiar power of judicial review, evaluating the constitutionality of legislation and executive action. However it was only 16 years after it was established that the Supreme Court granted itself the power to declare acts of Congress unconstitutional as a result of Marbury v. Madison. Similarly, the role of the President has significantly expanded over time, with the term the Imperial Presidencyaccounting for the increased powers gradually vested in the US executive since the administration of George Washington.

The US Constitution has similarly been amended, challenged and otherwise interpreted in a myriad of different ways over its lifetime, demonstrating a real-world divergence and interaction of de jure and de facto constitutional arrangements.

Constitutional catallaxy

Likewise, blockchains are constitutional orders governed by social norms as well as technical constraints. The de jure constitutional order which governs how BPs represent EOS token holders, and the ways in which disputes are resolved, are ultimately subject to the exercise of authority by those who have the means.

What we are seeing is a process of constitutional entrepreneurism — constitutional catallaxy — in the establishment of new economies. The institutions that coordinate activity in these economies change and adapt to both the technological limitations built into the protocols, as well as the mutual expectations and power of interacting stakeholders.

Crypto Public Choice

With Alastair Berg and Mikayla Novak

Abstract: This paper presents ‘crypto public choice’ which examines the economics of collective decision making in the functioning of blockchain protocols and among related communities of users. We introduce the blockchain community to public choice theory and show how it can be applied to the study of this technology. Public choice offers an extensive literature that can be applied to blockchain design, can interpret the actions of different types of blockchain users, and can explain governance problems and challenges in each of the blockchain protocols. Blockchains are institutional technologies which provide new ways in which to produce public goods including consensus over shared facts and the security of property rights. Collective decision making by users of blockchain protocols relates to consensus over the contents of a shared ledger, as well as the initial design and subsequent upgrading of these protocols.

Some economic consequences of the GDPR

With Darcy Allen, Alastair Berg and Jason Potts.

At the end of May 2018, the most far reaching data protection and privacy regime ever seen will come into effect. Although the General Data Protection Regulation (GDPR) is a European law, it will have a global impact. There are likely to be some unintended consequences of the GDPR.

As we outline in a recent working paper, the implementation of the GDPR opens the potential for new data markets in tradable (possibly securitised) financial instruments. The protection of people’s data is better protected through self-governance solutions, including the application of blockchain technology.

The GDPR is in effect a global regulation. It applies to any company which has a European customer, no matter where that company is based. Even offering the use of a European currency on your website, or having information in a European language may be considered offering goods and services to an EU data subject for the purposes of the GDPR.

The remit of the regulation is as broad as its territorial scope. The rights of data subjects include that of data access, rectification, the right to withdraw consent, erasure and portability. Organisations using personal data in the course of business must abide by strict technical and organisational requirements. These restrictions include gaining explicit consent and justifying the collection of each individual piece of personal data. Organisations must also employ a Data Protection Officer (DPO) to monitor compliance with the 261-page document.

Organisations collect data from customers for a range of reasons, both commercial and regulatory — organisations need to know who they are dealing with. Banks will not lend money to someone they don’t know; they need to have a level of assurance over their customer’s willingness and ability to repay. Similarly, many organisations are forced to collect increasingly large amounts of personal data about their customers. Anti-money laundering and counter-terrorism financing legislation (AML/CTF) requires many institutions to monitor their customers activity on an ongoing basis. In addition, many organisations derive significant value from personal data. Consumers and organisations exchange data for services, much off which is voluntary and to their mutual benefit.

One of the most discussed aspects of the GDPR is the right to erasure — often referred to as the right to be forgotten. This allows data subjects to use the government to compel companies who hold their personal data to delete it.

We propose that the right to erasure creates uncertainty over the value of data held by organisations. This creates an option on that data.

The right to erasure creates uncertainty over the value of the data to the data collector. At any point in time, the data subject may withdraw consent. During a transaction, or perhaps in return for some free service, a data subject may consent to have their personal data sold to a third party such as an advertiser or market researcher. Up until an (unknown) point in time — when the data subject may or may not withdraw consent to their data being used — that personal data holds positive value. This is in effect a put option on that data — the option to sell that data to a third party.

The value of such an option is derived from the value of the underlying asset — the data — which in turn depends on the continued consent by the data subject.

Rational economic actors will respond in predictable ways to manage such risk. Data-Backed Securities (DBS) might allow organisations to convert unpredictable future revenue streams into one single payment. Collateralised Data Obligations (CDO) might allow data collectors to package personal data into tranches of varying risk of consent withdrawal. A secondary data derivative market is thus created — one that we have very little idea of how it will operate, and what any secondary effects may be.

Such responses to regulatory intervention are not new. The Global Financial Crisis (GFC) was at least in part caused by complex and rarely understood financial instruments like Mortgage-Backed Securities (MBS) and Collateralised Debt Obligations (CBS). These were developed in response to poorly designed capital requirements.

Similarly, global AML/CTF requirements faced by financial institutions have caused many firms to simply stop offering their products to certain individuals and even whole regions of the world. The unbanked and underbanked are all the poorer as a result.

What these two examples have in common is that they both have good intentions. Adequate capital requirements and preventing money from being cleaned by money launderers are good things, but good intentions are not enough. Secondary consequences should always be considered and discussed.

Self-governance alternatives, including the application of blockchain technology, should be considered. These alternatives use technology to allow individuals greater control over the personal data they share with the world.

Innovators developing self-sovereign identity solutions are attempting to provide a market based way for individuals to gain greater control over — and derive value from — their personal data. These solutions allow users to share just enough data for a transaction to go ahead. A bartender doesn’t need to know your name or address when you want a drink, they just need to know you are of legal age.

Past instances of regulatory intervention should make us cautious that even well-meaning regulation will achieve its stated objectives with no negative effects. Self-sovereign identity, and the use of blockchain technology is a promising solution to the challenges of data privacy.

Identity as Input to Exchange

With Alastair Berg, Sinclair Davidson and Jason Potts

Abstract: Identity is an integral part of all but the most trivial economic, social and political transactions. Using transaction cost economics, we determine that identity costs are a distinct and measurable subset of transaction costs. In certain transactions, such as credit arrangements, identity costs are incurred at considerable expense for commercial and compliance based reasons. Vertical integration can be seen through the lens of identity cost economising, including in the financial sector, due to high costs of complying with KYC regulations as well as commercial risk management. Such organisational structure is also contingent on available identity technologies. The introduction of blockchain and distributed ledger technologies in identity applications may see new models of institutional structures develop.
