There is a word that has spent most of its history in the company of kings and constitutions, of treaties and territorial borders, of flags planted in earth or carried into battle. That word is sovereignty — and for most of recorded thought, it has been understood as something states possess and individuals, at best, are subject to.

That understanding has always been incomplete. The deeper history of the idea, traced carefully, reveals something more interesting: that sovereignty was never intrinsically a property of governments at all. It described a relationship between authority and a domain. And the question of who holds that authority — who is the rightful sovereign over what territory, what body, what identity — has been contested and progressively widened across centuries of careful argument. What began as the monarch’s claim over a kingdom eventually became the people’s claim over their government. What is now unfolding — haltingly, imperfectly, but with genuine philosophical force — is a further extension of the same movement: the individual’s claim over their own digital existence.

This is not a technical claim. It is a philosophical one. And it is worth taking seriously on its own terms, before considering what it means for the way identities are built, anchored, and held in the present era.

THE LONG ROAD FROM KINGS TO PEOPLE.

Sovereignty as a formal concept entered European political thought with Jean Bodin in the sixteenth century. Writing during the French religious wars, Bodin defined sovereignty as supreme power over citizens and subjects — power that was, in his account, perpetual and not restrained by ordinary law. His purpose was partly pragmatic: a France tearing itself apart needed a final authority, and Bodin sought to locate it firmly in the monarch. Thomas Hobbes, writing a century later in the shadow of the English Civil War, constructed a different but parallel account: without a sovereign power to enforce the peace, human life reverted to its natural condition — and the terms of that condition were not hospitable. Both Bodin and Hobbes conceived of sovereignty as authority that the people permanently transferred and alienated to an external entity, here the monarch.

The problem with this account, as later thinkers recognised, was that it provided no mechanism for the people to reclaim what they had surrendered. The theories of John Locke and Jean-Jacques Rousseau, challenging this in their different ways, led to the development of the doctrine of popular sovereignty that found expression in the American Declaration of Independence in 1776. Rousseau, in particular, held that sovereignty was inalienable: it could not be permanently transferred, because it resided in the collective body of citizens and expressed itself through their ongoing participation in civic life. The general will of the people could not simply be handed over and done with. It had to be continually exercised, or it atrophied.

The journey, in other words, has been one of progressive relocation. Sovereignty moved from monarch to nation, and from nation to people. Each movement involved a recognition that supreme authority was not self-evidently located where custom and power had placed it — that it could be argued for, claimed, and under the right conditions, shifted. The French constitution of 1791, in its famous formulation, declared that sovereignty is one, indivisible, inalienable, and imprescriptible, belonging to the nation — a statement that rang with revolutionary certainty but also foreclosed, deliberately, the idea that any individual could arrogate sovereign authority to themselves. This was a necessary corrective to monarchical tyranny. But it was not the final word on where sovereignty could legitimately rest.

THE SOVEREIGN INDIVIDUAL — A PHILOSOPHICAL THREAD.

Within the larger tradition of political theory, a distinct and sometimes overlooked strand has long concerned itself with the individual as the proper bearer of a particular kind of sovereignty. Not sovereignty over others, but sovereignty over oneself.

John Stuart Mill, writing in 1859 in his essay On Liberty, gave this idea its most durable formulation. In his conclusion to the analysis of past governments and their claims upon personal liberty, Mill proposed a single standard: that over himself, over his own body and mind, the individual is sovereign. Mill was not claiming that individuals were exempt from law or social obligation. He was arguing something more targeted: that there is a domain of self-regarding thought and action over which no external power — neither the state nor the pressure of social convention — holds legitimate authority. The only justification for interference with that domain was the prevention of harm to others. Everything else belonged to the person.

As the Stanford Encyclopedia of Philosophy has documented, Mill conceived of liberty as justifying the freedom of the individual in opposition to unlimited state and social control. What he described was not anarchy but a careful drawing of the line between the self and the social: a distinction between the person as citizen, subject to legitimate collective authority, and the person as individual, who retains a sovereignty that no democratic majority can simply override. The tyranny of the majority, Mill warned, was as real a threat to freedom as the tyranny of the monarch — perhaps more insidious, because it arrives wrapped in the language of the common good.

This strand runs alongside, and sometimes in tension with, the Lockean tradition of property and self-ownership. Locke proposed a radical conception of political philosophy deduced from the principle of self-ownership and the corollary right to own property. He famously argued that every person has a property in their own person, extending this to the labour of their body and the work of their hands. From this basis, Locke developed a labour theory of property: ownership of property is created by the application of labour to the common resources of the world. What a person works upon, improves, and transforms becomes theirs — not by the grace of a sovereign or the decree of a government, but by natural right. He further believed that property precedes government and government cannot dispose of the estates of subjects arbitrarily.

The implication is significant: for Locke, the individual’s domain of property is not something a legitimate government creates or grants. It is something a legitimate government exists to protect. The sovereign does not bestow ownership; the sovereign — if legitimate — merely recognises and secures what already belongs to the individual by right.

THE INTERNET'S ORIGINAL SOVEREIGNTY PROBLEM.

When the infrastructure of the digital world was designed, it was not designed with individual sovereignty in mind. That is not an accusation — it is a description of what the early internet was built to do. It was an open network for the exchange of information, constructed on protocols that had no native conception of identity. There was no authentication layer, no durable record of who a person was or what they owned. Identity was something platforms would add later, as a feature, not a foundation.

The consequence, as that infrastructure developed, was that identity became centralised by default. The W3C, in the preamble to its specification for Decentralised Identifiers, made this structural condition explicit: the vast majority of globally unique identifiers that individuals rely on are not under their own control. They are issued by external authorities that decide who or what they refer to and when they can be revoked. They are useful only in certain contexts, and recognised only by certain bodies not of the individual’s choosing.

Each service provider managed users’ identity. Users accessed services using credentials — usernames and passwords — that varied by service, and control of those credentials sat with the provider rather than the person. The centralised identity model became dominant not because it was philosophically sound, but because it was practically convenient and commercially useful. The federated identity model that followed — the capacity to authenticate across multiple services using credentials from a major platform — improved convenience while leaving the underlying problem intact. As the World Economic Forum has noted in its survey of self-sovereign identity, in the federated identity model, the sovereignty of identity remains with the identity service providers, not with the individual.

What those providers hold, they can withhold. What they store, they can lose. What they offer as a login, they can revoke. The individual account holder is, in every technical and legal sense, a tenant — not an owner.

This is, in the language of political philosophy, precisely the condition that Locke and Mill were each, in their different registers, arguing against. The individual holds no title to their digital identity under the current dominant model. They are licensed to use it. And a licence is not sovereignty. A licence is permission extended by a power that retains the ultimate right to withdraw it.

THE EMERGENCE OF SELF-SOVEREIGN IDENTITY.

The concept of self-sovereign identity emerged as a principled response to this structural condition. The term was articulated and popularised by Christopher Allen, who published a foundational article, “The Path to Self-Sovereign Identity”, in April 2016 — a date that Blockchain Commons has marked as a significant moment in the history of digital identity. The core notion, as the World Economic Forum has summarised it, is that users are given control and autonomy over their identity data — how it is used, and by whom. Although a universal definition is difficult to pin down, the argument is consistent: that individuals should be the ultimate authority over their own digital presence, not the platforms that currently hold it in trust.

The technical realisation of this idea has drawn on two standards developed through the World Wide Web Consortium: Decentralised Identifiers (DIDs) and Verifiable Credentials (VCs). DIDs are a new type of identifier that enables verifiable, decentralised digital identity. In contrast to typical federated identifiers, they have been designed so that they may be decoupled from centralised registries, identity providers, and certificate authorities. The controller of a DID can prove control over it without requiring permission from any other party. The W3C approved the DID 1.0 specification as an official recommendation on 19 July 2022 — a significant moment of international standardisation for an idea that had begun as a philosophical aspiration and a technical sketch.

Frontiers in Blockchain has described self-sovereign identity as embodying the fundamental human right to own and control a digital identity that grants access to public, social, and financial services. The principles that underpin SSI read, in important respects, like an application of Mill’s individual sovereignty to the digital domain: autonomy, meaning the individual has the freedom to choose what they share and with whom; consent, meaning the individual can consent to the use of their data in each instance; control, meaning the individual determines who accesses their identity data, and retains access to all of it themselves.

It is worth noting that the shift toward individual digital sovereignty has not proceeded without resistance. Centralised platforms built on the existing model have structural incentives to maintain it. When the W3C DID standard was formalised in 2021, Google, Apple, and Mozilla all raised objections — though, as observers have noted, it is perhaps unsurprising to encounter pushback from organisations whose models include monetising individuals’ identity data. The pattern is familiar from political history: those who hold sovereign power under existing arrangements rarely surrender it voluntarily. The movement of sovereignty from kings to peoples did not happen by consent. It happened through argument, through accumulated legitimacy, and through the construction of new institutional forms that made the old arrangements structurally obsolete.

TERRITORY, ADDRESS, AND THE SELF.

There is a resonance worth dwelling on between the territorial logic of state sovereignty and the spatial metaphors that govern digital identity. States assert sovereignty over bounded territories. Within those boundaries, they exercise supreme authority. The Stanford Encyclopedia of Philosophy has noted the parallel that international relations theorists draw between state sovereignty and private property: both involve the demarcation of domains, the assignment of authority, and the recognition of rights that others are bound to respect. The territorial and the proprietary are, at their structural core, the same kind of claim: this is mine, and that recognition carries binding force.

A digital address operates within a similar logic. It is a location within a namespace — a domain within which an identity is anchored and from which communications, representations, and interactions proceed. The question is whether that address is held on terms that resemble ownership or terms that resemble tenancy. Whether the individual is sovereign over it, or merely permitted to occupy it at the pleasure of a third party.

The internet’s current dominant architecture has made tenancy the default. Domain names registered through the traditional Domain Name System are subject to annual renewal, administrative control by registrars, and the ongoing governance decisions of ICANN and its constituent bodies. An individual who fails to renew, or whose registrar ceases to operate, or whose registration is challenged under dispute resolution procedures, can find their digital address revoked or reassigned. The identity is not property in any philosophically meaningful sense. It is a licence.

The onchain namespace model changes this relationship structurally. By anchoring identity to a blockchain record — a decentralised, cryptographically secured ledger that does not depend on any single administrator’s continued cooperation — it moves the address from the category of licence to the category of property. It does not merely offer a more convenient or durable service. It changes the fundamental terms of the relationship between the individual and their digital presence. A record on a distributed ledger, once written, persists without requiring anyone’s ongoing permission for it to remain valid.

This is not a trivial difference. It is the difference that Mill was identifying when he wrote about the self as a domain over which others have no legitimate authority. The domain, in this case, is literal: a name, an address, an identity anchored to a permanent record that no platform administrator can revoke and no policy change can expunge.

"Over himself, over his own body and mind, the individual is sovereign."

Mill wrote those words in a different context, about a different kind of domain. But the logic holds across domains. The question of who has final authority over the place where a person stands — whether that place is a piece of land, a body, or a digital address — is always and fundamentally a question about sovereignty.

THE CIVIC DIMENSION OF INDIVIDUAL SOVEREIGNTY.

It would be a mistake to read individual digital sovereignty as purely a private concern — as though it were only about personal convenience or the technicalities of access management. The civic dimension is real and significant.

The ACM Computing Surveys journal has described digital sovereignty as attracting increasing attention from the perspective of people’s ownership, custody, and control over their own digital assets, extending to inalienable user data rights of exercising self-determination over their data destiny. The language of inalienability here is directly descended from the Rousseauian tradition: there are things that belong to the person so fundamentally that they cannot be transferred or surrendered in any permanent or binding sense — only held or taken.

When a community owns its digital infrastructure — when the names and addresses that anchor its civic life are held as genuine property rather than as conditional licences — the community’s capacity for self-determination is strengthened in ways that regulation alone cannot achieve. Australia’s Privacy Act 1988, which established the Australian Privacy Principles governing the handling of personal information by government agencies and private sector organisations, represents one legislative attempt to assert something like sovereignty over personal data at the national level. But legislation operates at the level of governance over existing arrangements — it governs what platforms may do with data they hold, without changing the fundamental structural fact that they hold it.

Architecture and ownership are different instruments than law. They do not govern existing conditions; they establish new ones. An address held on a permanent, distributed ledger does not need a regulator to protect it from arbitrary revocation, because the conditions that would permit arbitrary revocation are not present in its architecture. The individual sovereignty it embodies is not a right that must be defended against institutional encroachment; it is a condition that is built into the structure of the thing itself.

WHAT QUEENSLAND'S ONCHAIN LAYER REFLECTS.

The project anchored through queensland.foundation is, among other things, a civic exercise in exactly this kind of individual sovereignty. The names registered across its six namespaces — name.queensland · name.brisbane · name.goldcoast · name.qld · name.surfersparadise · name.brisbane2032 — are not leased or licensed. They are owned, in the fullest sense that digital property currently supports: anchored to a blockchain record, held permanently, transferable at the holder’s discretion, and not subject to the renewal schedules, administrative decisions, or commercial imperatives of any centralised authority.

The philosophical tradition reviewed above helps clarify why this matters beyond the technical. When Locke argued that property precedes government and that government cannot dispose of subjects’ estates arbitrarily, he was making a claim about the proper relationship between individuals and the institutions that govern them. When Mill argued that over himself the individual is sovereign, he was drawing a line between the domain of the self and the domain of collective authority. When the advocates of self-sovereign identity argue that individuals should have complete control over their identity data and how it is used, they are extending the same line into a new terrain.

A permanent digital address in a civic namespace is one concrete way of standing on that line — of asserting, in the language that this era’s infrastructure understands, that this place, this identity, this name, belongs to the person who holds it. Not provisionally. Not subject to renewal. Not at the discretion of a platform that has its own interests in the matter.

The idea that sovereignty belongs to individuals as well as to states is not a new or radical one. It has been present in the best of the Western political tradition since at least the seventeenth century. What is new is the technical capacity to give it structural expression — to build the individual’s sovereignty over their digital domain into the architecture of the record itself, rather than relying on institutions to honour it after the fact.

THE ONGOING ARGUMENT.

Sovereignty has never been a settled question. The Oxford Handbook of the History of Political Philosophy notes that sovereignty has borne too many conflicting meanings over the centuries, and that even a definition flexible enough to accommodate much of the concept’s historical diversity must still be concrete enough to be meaningful — which it suggests is something like supreme authority within a territory. The history of that authority’s location — who holds it, over what domain, on what basis — is the history of political thought itself.

What is unfolding in the domain of digital identity is a new chapter in that history. The question of who holds supreme authority over the digital address, the name, the credential, the presence — whether it is the platform, the registrar, the state, or the individual — is a genuine political and philosophical question, not merely a technical one. And it is being answered, incrementally but structurally, by the architecture being built.

For a Queenslander who registers a permanent name in one of these civic namespaces, the philosophical significance may not be foregrounded. The practical significance — permanence, portability, ownership rather than rental — is immediate and legible without reference to Hobbes or Mill. But it is worth knowing that the claim being made is not merely commercial or administrative. It is a claim in a tradition that goes back to the most fundamental debates about where authority legitimately rests: with the institution that issues, or with the person who holds.

Mill’s formulation was precise: over himself, over his own body and mind, the individual is sovereign. The task of each era is to find the instruments through which that sovereignty can be made real — not just asserted, but structurally secured. A permanent onchain address, held without condition and without renewal, is one such instrument. Small in scale; significant in kind. The logic that moves it is the same logic that has been moving sovereignty toward the individual, steadily, for four centuries of argument.
