This article aims to explore The Upper Bound of Ethereum’s evolution from a “World Computer” to a “Civilizational Foundation”. We argue that the ultimate value of Ethereum lies in its role as the social operating system of a “Computational Civilization” — a programmable base layer that carries core civilizational elements such as wealth, identity, contract, and governance. By analyzing its triple foundations of technical, institutional, and cultural legitimacy, this paper systematically demonstrates Ethereum’s potential to become the root of civilization; furthermore, it explores its theoretical boundaries from four dimensions — technical, economic, governance, and social — ultimately defining the ultimate form of an “Ethereum Civilization” defined by physical limits, UBI, contestable sovereignty, and human-machine co-governance. The research concludes that The Upper Bound of Ethereum is essentially the limit of complexity, coordination, and secure evolutionary capacity that human social order can achieve on a programmable, verifiable foundation, offering a “meta-framework” for the safe evolution of civilization for the first time.

1. In the first paper, “Taming Leviathan,” we proposed the governance paradigm of “revocable authorization,” asserting that the legitimacy of power stems from its revocability, and revealed the important status of DAOs in governance practice. This paper further asks: What role will Ethereum play when the on-chain economic density and institutional complexity surpass those off-chain?

Ethereum’s narrative is undergoing a profound paradigm shift, evolving from a “protocol layer” focused on executing computation, to a “social operating system” that supports complex social collaboration. The Upper Bound of Ethereum is no longer defined by micro-indicators such as transaction throughput (TPS) or Gas fees, but by the institutional complexity, social scalability, and civilizational adaptability it can bear as the foundation of civilization.

More importantly, Ethereum has actually become the base layer for the human science fiction, the “Metaverse”. All functional modules and ecological synergy of the Metaverse must be built on top of Ethereum, as it is humanity’s first attempt to systematically reconstruct the underlying support for another parallel universe. Therefore, the core proposition of this paper is: Is The Upper Bound of Ethereum the limit of technical parameters, or the limit of human capacity to build civilizational complexity on a programmable foundation?

A system must pass the stringent test of legitimacy to bear civilization. Ethereum’s irreplaceable nature stems from the solid foundation it has built across the following three dimensions.

The consensus system, with over 1.06 million active validator nodes globally and more than 34 million ETH locked, makes the cost of attack far exceed any potential gain, establishing absolute security in an “economic physics” sense. Continuous technological changes greatly enhance Ethereum’s scalability, providing technical support for it to carry large-scale applications.

Quantum resistance and long-term security planning ensure that Ethereum can maintain long-term security in a rapidly iterating technological environment, providing sustainability guarantees for its role as civilizational infrastructure.

More importantly, protocol rules are enforced by code rather than human will. This “code is law” neutrality is the prerequisite for attracting diverse global entities to converge and collaborate, and it is a moat that other high-performance chains, which compromise on decentralization, cannot match.

Ethereum’s institutional legitimacy is reflected in its interaction with traditional governance systems and the maturation process of its internal governance mechanisms, which serves as the institutional guarantee for its role as a civilizational foundation.

Ethereum’s core value lies in transforming abstract social institutions (such as corporate law, contract law, governance charters) into composable, verifiable smart contracts, thus forming a programmable “social operating system”.

While Real-World Assets (RWA) are gradually moving on-chain, a deeper process based on the on-chain migration of the real world is unfolding — RWO (Real-World Organization).

The on-chain migration of RWO marks institutions themselves becoming composable “on-chain Legos” — identity modules, power modules, decision modules, financial modules, and auditing modules can be freely invoked, forked, and reorganized.

Ethereum’s institutional legitimacy will reach its ultimate establishment when human society’s institutions enter a “Three-Body-like” evolutionary stage where the cost of trial and error approaches zero, and the iteration speed is near real-time.

Ethereum’s core values include decentralization, censorship resistance, transparency, and security. The global spread of these values makes Ethereum not just a technological platform but also a cultural symbol and value system, providing the basis for cultural identity as a civilizational foundation.

The Ethereum community has grown into a global, diverse network, encompassing participants from different backgrounds such as technical developers, financial innovators, artists, and social activists.

The Ethereum community culture is deeply rooted with an anti-zero-sum and pro-positive-sum gene. This public spirit, which transcends short-term interests, is the “soft power” that unites global collaboration, allowing Ethereum to move beyond a purely technical scope and become a global community with shared values.

Based on the above legitimacies, Ethereum’s development will touch its theoretical cap in four dimensions. These boundaries collectively outline the profile of the “Ethereum Civilization”, while also defining the core constraints for Metaverse construction.

The path to scaling is the core way for Ethereum to break through its technical boundary. The prosperity of the Layer 2 ecosystem and the continuous increase in Blob capacity are important ways for Ethereum to break through technical boundaries.

According to the Ethereum Foundation’s long-term technical planning, Ethereum can continuously break through technical boundaries in the foreseeable future, providing technical support for its role as civilizational infrastructure. Under the modular architecture, its computing power is theoretically scalable to support global-level applications.

However, the physical speed of light will become the absolute boundary for consensus synchronization. When human civilization moves toward the stars, inter-planetary communication delays will force the unified Ethereum network to split into multiple relatively independent “consensus autonomous regions,” forming civilizational partitions based on physical distance.

Vitalik once suggested that “low-risk decentralized finance (DeFi) is to Ethereum what search is to Google,” sustaining Ethereum’s minimum value. This is Ethereum’s floor.

With the continuous development of Real-World Assets (RWA) + Real-World Organization on-chain (RWO) and Decentralized Physical Infrastructure Networks (DePIN), when the density of the on-chain economy and the complexity of its institutions surpass those off-chain, The Upper Bound of Ethereum is no longer defined by Earth’s GDP or market size, but is limited by the total complexity of the computational civilization.

At that time, its economic scale cap may reach several orders of magnitude above the Earth’s economy, becoming a “consensus economic universe” operated jointly by billions of humans and trillions of AIs.

In this system, the mechanisms for wealth creation and distribution will be reconstructed. The Global Basic Income (UBI) system will mainly consist of Node Dividend and Data Yield. $ETH will evolve into the fundamental unit for measuring the energy of the entire “consensus economic universe”. At this point, the essence of wealth is no longer the aggregation of assets in the traditional sense, but a function of the civilization’s capacity to coordinate complex activities. Therefore, The Upper Bound of Ethereum is truly the economic representation of the civilizational complexity it can support.

Ethereum’s governance boundary is reflected in its evolution from core developer dominance to multi-party co-governance, which is the governance foundation for its role as a civilizational root.

The Ethereum Foundation introduced four strategic pillars: accelerate, amplify, support, and long-term unblock, to support the ecosystem’s development. It also proposed the following two visions:

i. Maximize the number of people who directly or indirectly use Ethereum and benefit from its underlying values;

ii. Maximize the resilience of Ethereum’s technical and social infrastructure.

Ethereum has formed a multi-stakeholder governance model involving developers, validators, users, enterprises, and institutions. This pluralistic governance model can better balance the interests of different groups, enabling Ethereum to better adapt to complex ecosystem needs, thus providing governance assurance for its role as a civilizational root.

The development of Decentralized Autonomous Organizations (DAO) is an important manifestation of the expansion of Ethereum’s governance boundary.

Based on a Decentralized Society (DeSoc) formed by SBTs (Soulbound Tokens), individuals can seamlessly migrate their biometric characteristics (identity), capabilities, behavior, health, and wealth between different DAOs (which can be viewed as “digital city-states”). The role of real-world nations will gradually shift to “physical world public service providers” (public health, security). Ethereum, in turn, will become the “transnational constitutional layer,” setting underlying rules like “identity confirmation, asset protection”. Global governance will thus form a “layered legal order” of “Real-World Governance (Nation/Community) + On-Chain Governance (Constitutional Layer) + DAO Governance (Application Layer)”.

From this, a new system of contestable sovereignty emerges: power gains legitimacy through competition, governance achieves optimization through migration, and institutions complete iteration through consensus. “Sovereignty competition” will become the driving force for the continuous evolution of future society, and the quality of governance will be decided by the real-time voting of citizens’ migration data (“voting with their feet”).

Ethereum’s social boundary is reflected in its evolution from an experiment by a few technical enthusiasts to a social infrastructure involving the global public, which is the social foundation for its role as a civilizational root.

Continuous optimization of user experience is a key way for Ethereum to break through social boundaries, enabling it to attract more non-technical users and expand its social base.

Enhancing localization and cultural adaptability is an important strategy for Ethereum to break through social boundaries; encouraging developers and users from different regions to build applications and services based on local needs and cultural characteristics allows Ethereum to better integrate into different social environments, providing a cultural foundation for its role as a civilizational root.

Expanding education and knowledge dissemination is an important way for Ethereum to break through social boundaries, enabling it to cultivate a broader talent base, providing human resource support for its long-term development.

When the abundance and depth of human digital identity (via technologies like SBT) and the on-chain activities of AI Agents collectively form the mainstream of social interaction, Ethereum will evolve into a neutral “Human-Machine Interaction Field”. Social governance will be jointly participated in by humans and silicon-based intelligence with on-chain personalities, and the social form will ultimately evolve into an inter-species consciousness community, making coordination intelligence Ethereum’s ultimate social function.

In this stage, Ethereum is no longer an extension tool of human society, but the new form of society itself — an operating system where humans and silicon-based intelligence co-inhabit.

In summary, the exploration of the technical, economic, governance, and social boundaries ultimately converges into a qualitative leap — when the core elements of civilization are encoded onto a programmable foundation, its evolutionary paradigm shifts from the slow, friction-filled, rigid iteration to agile, reversible, elastic evolution. This marks a systemic error-correction capability becoming an intrinsic attribute of civilization.

British physicist David Deutsch pointed out in The Beginning of Infinity: When a civilization masters a systemic error-correction mechanism, its progress will no longer have an upper limit.

This “infinitely correctable” capacity is the very source of civilization’s sustained evolution. Ethereum is precisely the technological realization of this error-correction mechanism. On Ethereum, social institutions are no longer unchangeable codes of law, but updatable code; power is no longer a static monopoly, but revocable authorization; governance is no longer a single design, but a continuous iteration process. This “institutional programmability” is essentially the “civilizational correctability”. It allows society to enter an operational mode of low-cost trial-and-error and high-frequency evolution, making the speed of institutional updates align with the speed of technological innovation for the first time.

When the social contract can be improved, copied, and forked like open-source software, humanity truly steps into a “beginning of infinity”: a civilizational stage that does not aim for perfection, but where continuous error correction and evolution are the norm.

This marks a fundamental leap for human society: from irreversibility to reversibility, from power monopoly to power mobility, and from institutional closedness to institutional openness.

Therefore, The Upper Bound of Ethereum is not a static endpoint, but an eternally activated “beginning of infinity” — a continuous, unbounded civilizational process driven by programmable institutions, revocable power, and iterative governance.

Ethereum’s ultimate form is not any specific civilizational vision, but becoming a meta-framework for digital civilization — an underlying foundation that allows countless forms of civilization to be safely born, compete, evolve, and perish. It does not define the ultimate goal of civilization, but provides the necessary rules and soil for evolution.

As a meta-framework, Ethereum’s core is to establish a field for the infinite game. Within this field, all participants are engaged not in a finite game with an endpoint (such as winning an election, defeating an opponent), but in an infinite game aimed at making the game itself continue forever — that is, the continuation and prosperity of civilization itself.

Programmable institutions constitute the game’s mutable rules, allowing the social contract to iterate at the speed of code, enabling low-cost trial-and-error and high-frequency evolution.

Trustworthy neutral execution ensures the impartiality of the rules. Any participant, regardless of their strength, interacts under the same set of rules, which is the premise for the game’s continuation.

Contestable sovereignty introduces a competition mechanism for the rules. Different DAOs (“digital city-states”) can offer different governance models, cultural values, and economic systems. Individuals choose by “voting with their feet,” thereby driving the continuous optimization of the entire system.

Therefore, The Upper Bound of Ethereum is not a quantifiable technical metric, but the limit of complexity and coordination that a civilization can achieve after placing its core institutions on a programmable, verifiable foundation. Its limit is not the limit of computing power, but the limit of social coordinability. When a civilization’s institutions can be updated like code, and values can be freely migrated through consensus, human society enters a calculable, verifiable, and evolvable order space for the first time — this is the true meaning of the “Civilizational Cap”.

This civilizational meta-framework is not a castle in the air; its first, and most intuitive instance, is the Metaverse of human science fiction. In fact, Ethereum has objectively become the only viable base layer for constructing any true sense of the Metaverse.

The Metaverse is not merely a “virtual game” or “digital space”, but a parallel universe that requires “uniquely trusted identity, clear asset ownership, inviolable contracts, and highly efficient governance synergy” — these core needs are perfectly met by Ethereum’s underlying system:

Decentralized Identity (DID/SBT) ensures uniquely trusted and autonomous identity;

Non-Fungible/Fungible Tokens (NFT/FT) achieve clear asset ownership and global liquidity;

Smart Contracts guarantee inviolable and automated contract execution;

Decentralized Autonomous Organizations (DAO) support highly efficient governance synergy and revocable authorization.

In other words, all functional modules and ecological synergy of the Metaverse must be built on top of Ethereum or a similar trustworthy neutral base layer. Any so-called “Metaverse” that departs from this foundation, no matter how spectacular its visuals, will eventually fall into the traditional internet traps of platform monopoly or data silos, unable to become a true “parallel universe” where rights are fundamentally protected and the economy can freely thrive. Therefore, Ethereum is not just the civilizational framework; it is already the Constitution and the cornerstone of the Metaverse.

From its very first “Genesis Block,” Ethereum has harbored the ambition to transcend technology. This paper systematically demonstrated its triple legitimacy, four boundaries, and ultimate form as a social operating system.

When identity, wealth, and governance fully migrate on-chain, Ethereum is no longer just a tool, but the “Promised Land of Digital Civilization”. Here, we are not merely users of code, but the founders jointly writing the social contract of the future.

The “possible future” envisioned by Vitalik is the path of technological implementation, while the “ultimate form” revealed in this paper is the underlying rule of civilizational evolution. Ethereum becomes the underlying protocol for all social experiments, and The Upper Bound of Ethereum is a function of humanity’s collective wisdom and capacity for collaboration — this is an infinite game that never ends.

From “Genesis Block” to “Genesis Civilization”, The Upper Bound of Ethereum is ultimately a reflection of our determination and imagination in choosing where to go together. It carries not only the evolution of a new technology but also humanity’s first attempt to build another universe in the digital frontier, and its boundary is the horizon of human collaboration and imagination.
