The Sophia Protocol: A Framework for a Decentralized Digital Commonwealth

Abstract

The Sophia protocol introduces an integrated framework designed to address the foundational trilemma of decentralized social systems: achieving equitable economic distribution, ensuring authentic human participation, and implementing adaptive, resilient governance.

It combines a demurrage-based mutual credit system for Universal Basic Income (UBI), a hybrid Proof of Personhood (PoP) model for Sybil resistance, and a novel governance mechanism termed "Adaptive Futarchy" that integrates Liquid Democracy with prediction markets. The entire system is architected to operate on a high-throughput, secure ZK-Rollup infrastructure.

This paper details the protocol's theoretical underpinnings, its specific design choices informed by an analysis of historical and contemporary systems, and a critical examination of its potential failure modes and embedded mitigation strategies.

Introduction: The Trilemma of Digital Social Systems

Problem Statement

The proliferation of digital networks and decentralized technologies has created unprecedented opportunities for global coordination and value creation. However, these systems consistently encounter a foundational trilemma, a set of three interconnected challenges that must be solved simultaneously for any large-scale digital society to achieve long-term stability and legitimacy.

Existing platforms, whether centralized social networks or decentralized protocols, have largely failed to provide a holistic solution, typically optimizing for one or two aspects at the expense of the third. This trilemma comprises the challenges of economic equity, authentic identity, and effective governance.

Economic Inequity: The r > g Dynamic

The first and most pervasive challenge is the natural tendency of open economic systems toward wealth concentration. French economist Thomas Piketty, in his seminal work Capital in the Twenty-First Century, identified a central dynamic driving this phenomenon: when the rate of return on capital (r) is consistently greater than the rate of economic growth (g), wealth held by the owners of capital will compound faster than the income generated by labor and output.1

This fundamental inequality, expressed as r>g, is not an anomaly but a historical norm, interrupted only by catastrophic events like the World Wars. Over the long term, it leads to an inexorable concentration of wealth in the hands of a small minority, causing profound social and economic instability.1 In the context of digital economies, particularly those with tokenized assets, this dynamic is often accelerated. Early adopters and large capital holders can accumulate a disproportionate share of network assets, creating plutocratic structures that undermine the promise of a more equitable financial system. Any protocol for a digital commonwealth must therefore incorporate a mechanism that actively counteracts this concentrating force.

Identity Crisis (The Sybil Problem)

The second challenge is the crisis of identity. The core value proposition of permissionless networks is their openness, but this very openness makes them acutely vulnerable to the Sybil attack.

In a Sybil attack, a single adversary creates a large number of pseudonymous identities to gain a disproportionately large influence over the network.3 This attack vector fundamentally subverts any system that relies on a "one person, one vote" or "one person, one share" principle. It allows attackers to drain resources from systems designed for fair allocation, such as airdrops or UBI, and to overwhelm democratic governance processes by creating an illusion of widespread consensus.3

This long-standing problem has been supercharged by the advent of advanced artificial intelligence. AI models can now mimic human behavior with startling fidelity, generate creative content, and hold conversations, blurring the lines between human and machine interaction.5 Traditional methods of Sybil resistance, such as CAPTCHAs, are becoming increasingly obsolete as AI can now solve them or even socially engineer humans into solving them on its behalf.5

Consequently, a robust, scalable, and privacy-preserving Proof of Personhood (PoP)—a mechanism to verify that a given digital account corresponds to a unique living human—is no longer a niche technical requirement but a piece of critical infrastructure for the future of the internet.7

The Governance Deficit

The third challenge is the deficit in effective and legitimate governance. Decentralized Autonomous Organizations (DAOs) and other protocols have experimented with various governance models, but each has revealed significant flaws. The most common model, token-weighted voting, devolves into plutocracy, where the wealthiest token holders dictate the rules of the system, often for their own benefit. An analysis of major protocols like MakerDAO reveals a significant concentration of voting power in the hands of a few large holders, creating a risk of centralized decision-making despite the decentralized architecture.8

Alternative models also present trade-offs. Liquid Democracy, which allows users to delegate their votes to trusted experts, has been shown to suffer from its own power concentration problems, where a small number of "super-delegates" can amass immense influence.9

Futarchy, a model that uses prediction markets to select policies, is theoretically powerful but vulnerable to market manipulation and, more fundamentally, to the corrosive effects of Goodhart's Law, where the metric being optimized ceases to be a good measure of true welfare.12

The absence of a governance model that is simultaneously scalable, resistant to capture, and capable of adaptive learning represents a critical failure point for any long-lived decentralized system.

The Sophia Proposition

The Sophia protocol is proposed as an integrated, holistic solution to this trilemma. Its architecture is not a collection of disparate features but a co-designed system where the economic, identity, and governance layers are mutually reinforcing. The protocol's name, derived from the Greek word for "wisdom" (σoϕιˊα), reflects its core objective: to create a framework that enables collective intelligence, fosters equitable coordination, and builds a resilient digital commonwealth. Sophia's design is predicated on the understanding that the three problems of the trilemma are not independent but are deeply and causally linked. A failure in one domain inevitably cascades into the others, creating vicious cycles.

For instance, an economic system designed for UBI cannot function without a robust PoP system to prevent Sybil attackers from draining its resources.14 The entire premise of a universal income relies on the ability to uniquely identify each human recipient. A Sybil attack in this context is not a minor issue but an existential threat that would trigger hyperinflation and an immediate collapse of the currency's value.

Similarly, a governance system operating within an economic model prone to the r > g dynamic will inevitably be captured by the wealthy. As capital concentrates, so does voting power in token-based systems, leading to a feedback loop where the rules of the protocol are further skewed to benefit capital holders, accelerating inequality.1

Finally, an identity system requires a means of adapting to new threats, such as more sophisticated AI-driven deepfakes. Without an effective and legitimate governance mechanism to approve and implement necessary upgrades, the PoP system becomes static and brittle. Eventually, it will fail, and this failure of identity will, in turn, compromise the integrity of both the economic and governance layers that depend on it.

Sophia's architecture is therefore designed to create virtuous cycles. Its economic model promotes broad distribution, which decentralizes power in its governance system. Its identity system ensures that economic benefits and governance rights are allocated fairly, on a "one human, one share" basis. And its governance system provides the means to adapt and evolve all parts of the protocol in response to new challenges and changing community values. The strength of the Sophia protocol must be evaluated not on the merits of its individual components, but on the resilience and synergy of their integration.

Part I: The Sophia Economic Model: A Demurrage-Based Mutual Credit System

The economic model of the Sophia protocol is engineered to serve as the system's circulatory system, designed for high velocity of exchange, equitable distribution of value, and structural resilience against the common failure modes that have plagued alternative and community currency systems. It directly confronts the wealth-concentrating tendencies of conventional economies by embedding principles of redistribution and circulation into the very nature of its currency.

1.1. Foundational Principle: Counteracting r > g with a Universal Basic Income

The protocol's economic architecture is a direct and deliberate response to the long-term structural inequality identified by Piketty's r > g dynamic.1

In a system where capital's returns outpace overall economic growth, a passive accumulation of wealth by asset holders is the default outcome. To counteract this, the Sophia protocol institutes a Universal Basic Income (UBI) not merely as a social welfare program, but as a fundamental rebalancing mechanism built into its monetary policy.

The mechanism is straightforward: every verified human identity, as established by the protocol's identity framework (detailed in Part II), is entitled to a regular, unconditional issuance of the protocol's native unit of account, Sophia Credit (SC). This issuance is the primary means by which new currency enters the system, directly linking the growth of the money supply to the number of living human participants. This approach is inspired by the conceptual models of blockchain-based UBI projects such as Circles UBI and the UBI token built on the Proof of Humanity registry, which aim to establish a fair and ongoing distribution model accessible to all.14

By providing a constant, universal inflow of credit, the UBI establishes an economic floor for every participant, ensuring a baseline of economic security and fostering broad-based participation in the network's economy. It acts as a permanent countervailing force to wealth concentration, continuously redistributing a portion of the system's value to all members of the commonwealth.

1.2. Core Engine: A Mutual Credit System

To ensure a flexible and demand-driven money supply, Sophia is not built upon a pre-minted or centrally issued token. Instead, it operates as a mutual credit system. In this model, each participant's account is created with a zero balance. Money is created endogenously through the act of transaction itself. When one participant wishes to transact with another, they can extend credit up to a pre-defined limit, creating a positive balance in the recipient's account and a corresponding negative balance in their own.

This design directly addresses one of the most common failure modes of historical Local Exchange Trading Schemes (LETS) and other community currencies: liquidity shortages.16 In many of these systems, economic activity can grind to a halt simply because there is not enough "money" in circulation to facilitate desired trades. Participants may have valuable goods or services to offer but are unable to transact due to a lack of a medium of exchange.

In a mutual credit system, this problem is circumvented. The act of trading itself creates the necessary liquidity at the moment it is needed, ensuring that the money supply can dynamically expand and contract in response to the actual economic activity of the network's participants. This creates a more organic and resilient economic environment, less prone to the artificial constraints of a fixed money supply.

1.3. The Catalyst: Demurrage as a Negative Interest Rate

While the UBI provides a distributive foundation and mutual credit provides liquidity, a critical third component is required to ensure the system's dynamism and long-term viability. The primary failure mode observed in the Circles UBI pilot in Berlin was not a lack of liquidity, but a lack of a closed economic loop. The vast majority of participants, particularly businesses, did not circulate their UBI tokens within the local economy. Instead, they immediately cashed them out for fiat currency (Euros) to pay for expenses denominated in the mainstream economy, such as rent and external suppliers.15

This "exit-to-fiat" behavior broke the intended circular flow of value, turning the UBI into a one-time subsidy rather than the lifeblood of a new economy. This mirrors a similar failure mode in historical LETS, where participants would accumulate credits but, finding little to spend them on, would hoard them, leading to low trading volumes and eventual system stagnation.16

To solve this critical problem, the Sophia protocol implements a demurrage fee. First proposed by the heterodox economist Silvio Gesell, demurrage is a small, periodic holding cost applied to positive currency balances.18 It functions as a form of negative interest rate, making the currency an inefficient store of value but a highly efficient medium of exchange.19 Gesell famously argued that for money to effectively facilitate the exchange of perishable goods, it too must be perishable, that it should "go out of date like a newspaper, rot like potatoes, rust like iron".20

In the Sophia protocol, this principle is implemented algorithmically. A small, fixed percentage of all positive Sophia Credit balances is automatically deducted at regular, frequent intervals (e.g., daily). This deducted value can either be returned to a common pool for redistribution or be permanently removed from the supply (burned). This simple mechanism creates a powerful and persistent incentive for every holder of SC to spend or invest their credits rather than letting them sit idle and decay in value.

The intended effects of demurrage are well-documented in both theory and historical practice .19:

Increased Velocity of Money: The primary effect of demurrage is a dramatic increase in the velocity of money. By penalizing hoarding, it compels circulation. Historical experiments with demurrage currencies, such as the Wörgler Schwundgeld in Austria during the 1930s, demonstrated this effect powerfully, showing a significant increase in economic activity and even incentivizing participants to pay their taxes in advance to offload the depreciating currency.19 In Sophia, this ensures that the UBI issuance does not stagnate in a few accounts but flows rapidly through the economy, stimulating trade and creating a vibrant internal market.
Prioritization of Exchange over Store of Value: Demurrage deliberately degrades the currency's function as a long-term store of value. This discourages speculative hoarding and financialization, keeping the currency focused on its primary purpose: facilitating the exchange of real goods and services within the commonwealth.
Discouraging Cash-Out Behavior: While exchanging SC for other currencies remains possible, demurrage makes holding SC for the purpose of eventual conversion to fiat a costly strategy. A business receiving SC is faced with a clear economic choice: either convert it to fiat immediately (incurring exchange fees) or let it sit in their account and lose value to demurrage. This creates a third, more attractive option: find a supplier or employee within the Sophia network who accepts SC, thereby preserving the full value of the credit by passing it on.

This incentive structure represents more than a simple economic tweak; it is a profound behavioral and systemic design principle. Demurrage actively discourages the "exit-to-fiat" mentality that doomed the Circles pilot and instead applies a continuous, gentle pressure on all participants to seek out and build internal economic relationships. The problem for a participant is no longer "How can I be convinced to use this new currency?" but rather "What is the most efficient way for me to spend this depreciating currency before it loses value?"

This shift in the rational economic calculus is designed to make the economic model self-catalyzing. The UBI provides the initial potential energy in the form of universal liquidity. The demurrage mechanism then acts as a catalyst, converting that potential energy into the kinetic energy of exchange and directing that energy inward, fostering the very economic circularity that is essential for the system's long-term independence and viability. It bootstraps the network effect by making active participation not an ideological choice, but a rational economic decision to avoid the explicit cost of inaction.

Part II: The Sophia Identity Framework: Hybrid Proof of Personhood

The integrity of the Sophia protocol's economic and governance systems rests entirely upon a single foundational assumption: the ability to reliably and uniquely identify each human participant. Without a robust defense against Sybil attacks, the UBI would be drained by fraudulent claims, and the democratic governance process would be subverted by manufactured votes.

The Sophia Identity Framework is therefore architected as a multi-layered, defense-in-depth system. It is designed to provide strong Sybil resistance while navigating the complex trade-offs between privacy, accessibility, and decentralization. The core principle is resilience through diversity, acknowledging that any single method of Proof of Personhood (PoP) can and likely will be compromised over time.

2.1. The Necessity of a Robust PoP Framework

The function of the PoP framework is singular and critical: to ensure that each stream of Universal Basic Income and each unit of voting power in the governance system corresponds to one, and only one, unique living human being. This is the bedrock upon which the entire protocol is built. The threat model is diverse and evolving, ranging from low-cost, automated bots attempting to create thousands of fake accounts, to sophisticated AI-generated deepfakes capable of passing rudimentary liveness tests, and extending to the risk of state-level actors attempting to coerce or counterfeit identities on a massive scale.3

A successful PoP system must be resilient against this full spectrum of attacks.

2.2. Pillar 1: Privacy-Preserving Biometric Onboarding

Biometric data, such as an iris pattern or facial geometry, offers a powerful and scalable foundation for establishing the uniqueness of an individual. This is the approach taken by projects like Worldcoin, which uses a specialized hardware device, the Orb, to scan users' irises.21

However, as articulated by critics including Ethereum co-founder Vitalik Buterin, a purely biometric approach is fraught with significant risks related to privacy, centralization, and accessibility.7

A centralized entity controlling the hardware and the database of biometric hashes represents a single point of failure and a tempting target for attackers or oppressive governments. Furthermore, reliance on proprietary hardware creates significant accessibility barriers.

The Sophia protocol adopts a biometric layer designed to mitigate these specific risks:

Open Hardware Standards: To avoid the centralization risk of a single proprietary device like the Orb, the Sophia protocol will not produce its own hardware. Instead, it will define and support an open standard for biometric verification hardware. This allows a competitive, decentralized ecosystem of "Verifier" devices to emerge, built by various manufacturers and operated by independent entities. This prevents any single company from controlling the physical gateways to the network.23
Zero-Knowledge Proofs (ZKPs) for Privacy: The verification process is engineered for maximum privacy using Zero-Knowledge Proofs. When a user undergoes a biometric scan with a Verifier device, the system proves the uniqueness of their biometric template without ever revealing the template itself.26 The user's wallet generates a cryptographic key pair, and the Verifier device generates a ZKP attesting that a) a live human was present, and b) their biometric data is unique within the system's database of existing commitments. This proof is then used to issue a W3C-standard Verifiable Credential (VC) to the user's wallet.
Data Minimization and On-Chain Anonymity: Crucially, no raw biometric data ever leaves the user's device or the secure enclave of the Verifier hardware. The on-chain footprint of a successful verification is minimal: a cryptographic commitment (a hash of a secret known only to the user) is added to the system's Merkle tree of verified identities, and a corresponding nullifier (a value derived from the secret, which can only be revealed once) is published when the user wishes to perform an action. This "commit-and-reveal" scheme prevents the creation of a public database of biometric hashes that could be cross-referenced to de-anonymize users—a key privacy risk identified in critiques of Worldcoin.7

2.3. Pillar 2: A Sybil-Resistant Web of Trust (WoT)

A purely biometric system, even one with strong privacy protections, is brittle. A breakthrough in AI-generated biometrics or a compromised hardware manufacturer could lead to a catastrophic failure. To provide a complementary and human-centric layer of security and recovery, the Sophia protocol integrates a Web of Trust (WoT). However, traditional WoT services have demonstrated significant logical vulnerabilities that can be exploited to spoof identities and attestations.
Sophia's WoT is designed to be resilient against these known failure modes:

Vouching Mechanism: Already verified members of the network can "vouch" for new users they know and trust to be real, unique humans. This vouch takes the form of a cryptographically signed Verifiable Credential issued from the voucher to the new user. To achieve a baseline level of trust within the network, a new user must collect a threshold of vouches (e.g., 3-5) from established members with a good reputation.
Mitigating Logical Flaws: The system's design directly counters the types of attacks that have been successful against other WoT services.29
- Immunity to Content Distribution Attacks: Vouching attestations are not scraped from public social media timelines. An attacker cannot trick a user into "retweeting" or "forking" a malicious post containing a hidden token. Instead, vouches are structured data (VCs) that are transmitted directly between wallets and recorded in a dedicated, on-chain registry. This ensures the authenticity and explicit intent of every vouch.
- Immunity to Namespace and Redirect Attacks: Verification is based on the cryptographic signature of a user's Decentralized Identifier (DID), not on the presence of a specific file (e.g., keybase.md) at a particular URL. This makes attacks that rely on filename collisions or malicious redirects entirely irrelevant to the Sophia WoT.
Economic Disincentives for Collusion: To increase the cost of creating a Sybil network through a colluding group of vouchers, the protocol requires an economic stake. When a member vouches for a new user, they must lock a small amount of Sophia Credit as a bond. If the vouched user is later identified as a Sybil through a governance challenge, the vouchers who attested to their humanity forfeit their staked bonds and suffer a significant, lasting penalty to their on-chain reputation score. This imposes a direct and escalating economic cost on attempts to subvert the social graph, a key principle of Sybil resistance.3

2.4. Pillar 3: A Flexible Ecosystem of Verifiable Credentials (VCs)

While biometrics and social graphs can establish that a user is a unique human, they do not convey any other attributes or claims about that person. The W3C Verifiable Credentials (VC) data model provides a standardized, interoperable, and user-centric framework for representing, holding, and presenting such claims.32

The Sophia Identity Wallet is designed as a standard-compliant holder for VCs, enabling a rich and flexible identity ecosystem:

Protocol-Issued Credentials: The biometric onboarding process issues a "Proof of Uniqueness" VC. The WoT vouching process results in the user holding a set of "Social Vouch" VCs from their peers.
Third-Party Integration: The real power of the VC model lies in its extensibility. The protocol allows any trusted third-party issuer—such as universities, employers, professional organizations, or even governments—to issue VCs to Sophia users. A user could hold a "Proof of Degree" VC from their university, a "Proof of Employment" VC from their company, or a "Proof of Citizenship" VC from a government agency, all within the same wallet.
Selective Disclosure with ZKPs: The integration with ZKPs allows for powerful privacy-preserving interactions. A user can generate a zero-knowledge proof from their VCs to prove a specific fact without revealing the underlying data. For example, a user could prove to a service that they hold a valid "Proof of Uniqueness" VC (and are therefore human) without revealing their identity or which specific VC they hold. Similarly, they could use a government-issued VC containing their date of birth to prove they are over 18 without disclosing their actual birthdate, name, or address.28

This hybrid model of identity creates a system of progressive trust and offers multiple pathways to participation, directly addressing the critical accessibility and inclusivity failures of monolithic PoP systems. A system like Worldcoin presents a binary choice: either you have access to an Orb and are willing to have your iris scanned, or you are entirely excluded from the network.7

This creates a stark digital divide. A pure WoT system, conversely, can be difficult to bootstrap and may exclude individuals who are socially isolated or new to a community.7

Sophia's hybrid model resolves this tension by creating a spectrum of trust.

A user can achieve the highest level of assurance, Trust Level 3 (TL3): Biometrically Verified Human, by completing the privacy-preserving biometric onboarding. This status grants them the full UBI issuance and maximum weight in the governance system.
Alternatively, a user can enter the system through the social graph, collecting vouches from existing members to achieve Trust Level 2 (TL2): Socially Vouched Human. This status might grant them a partial UBI and limited governance rights, but it provides a crucial accessibility ramp for those who lack access to, or are distrustful of, biometric hardware.
A user who joins at TL2 can, at any time, "upgrade" their status to TL3 by completing the biometric verification process.
The VC ecosystem adds further nuance. A user with a TL2 identity who also holds a highly trusted VC from a reputable external issuer (e.g., a university) could be granted access to specific applications or services within the ecosystem that require a higher level of assurance than TL2 but do not strictly require biometrics.

This architecture results in a far more inclusive, flexible, and resilient identity framework. It avoids the "all-or-nothing" fragility of a single-method PoP system and instead fosters a nuanced ecosystem of identity and trust that is more reflective of the complex, multi-faceted nature of identity in the real world.

Part III: The Sophia Governance Protocol: Adaptive Futarchy with Liquid Delegation

The governance of the Sophia protocol requires a system that can effectively harness the collective intelligence of its members to make wise decisions, while actively resisting the common failure modes of plutocracy, power concentration, and strategic manipulation. To achieve this, Sophia implements a novel, hybrid governance mechanism called "Adaptive Futarchy." This system separates the process of deciding on collective values from the process of choosing the best strategies to achieve them, and it builds in a feedback loop designed to make the entire system resilient to metric fixation and gaming.

3.1. The Core Principle: "Vote on Values, Bet on Beliefs"

The foundational concept of the Sophia governance model is Futarchy, a framework first proposed by economist Robin Hanson.35 Futarchy's core insight is that traditional voting mechanisms conflate two distinct types of questions: questions of values (what do we want to achieve?) and questions of beliefs (what is the most effective way to achieve it?). By attempting to answer both with a single vote, we often do a poor job of answering either.

Futarchy proposes a clear separation of these two processes:

Voting on Values: The community, as a collective, uses a democratic process to define its goals. In the context of a protocol, this means deciding what success looks like and codifying it into a clear, objective, and quantifiable "Welfare Metric." This metric could be a composite formula that includes variables like network transaction volume, the Gini coefficient of SC holdings (to measure inequality), user retention rates, or any other measurable outcome the community deems important.
Betting on Beliefs: Once a Welfare Metric is established, the question of how to best improve it is turned over to the information-aggregation mechanism of prediction markets. When a specific policy is proposed (e.g., "Change the demurrage rate to 0.5% per week"), participants do not vote directly on the proposal. Instead, they bet on its outcome. The market mechanism determines which policy is most likely to maximize the agreed-upon Welfare Metric.

This separation allows the protocol to benefit from the best of both worlds: democratic legitimacy in setting its ultimate goals, and the unparalleled ability of markets to aggregate dispersed information and incentivize truthful forecasting to find the most effective strategies to reach those goals.36 It forces participants who have strong beliefs about a policy's effectiveness to back those beliefs with a financial stake, thereby rewarding accurate predictions and penalizing uninformed or manipulative ones.35

3.2. The "Values" Layer: Liquid Democracy for Metric Selection

The most critical question in a futarchy is: who decides the Welfare Metric? A static, hard-coded metric is doomed to fail. It will either become obsolete as the protocol's environment changes, or, more likely, it will be gamed. Therefore, the process for selecting and amending the Welfare Metric must itself be a robust and legitimate governance process.

For this "values-level" decision-making, the Sophia protocol employs a Liquid Democracy (LD) module.9 Liquid Democracy is a dynamic form of representation that sits between direct democracy and representative democracy. In this system:

Every verified human participant can vote directly on high-level "values" proposals, such as adopting a new Welfare Metric or amending the protocol's constitution.
Alternatively, any participant who feels they lack the time or expertise to evaluate a proposal can delegate their voting power to another participant or an expert committee whom they trust on that specific issue domain.10
These delegations are transitive (a delegate can delegate the votes they have received to another delegate) and are "liquid" (they can be reassigned or revoked at any time).

This model allows for specialization and the emergence of trusted experts, while preserving the ultimate sovereignty of the individual voter. However, LD is not without its own documented risks, most notably the tendency for voting power to concentrate in the hands of a few highly visible "super-delegates".9 To mitigate this risk, Sophia's LD module incorporates several safeguards:

Reputation-Weighted Voting: To counterbalance the influence of wealth or popularity, voting power within the LD module can be optionally weighted by a non-transferable reputation score. This score is earned through sustained, positive contributions to the ecosystem (e.g., successful proposals, accurate market predictions, reliable vouching). This creates a hybrid model that values both democratic representation and demonstrated expertise, moving away from pure token-based or simple one-person-one-vote systems.42
Delegation Caps: The protocol can implement governance-approved caps on the total number of delegations a single entity can accumulate. This can be a "soft" cap that reduces the weight of additional delegations beyond a certain threshold or a "hard" cap that prevents them entirely, ensuring a more distributed landscape of influence.

3.3. The "Beliefs" Layer: Conditional Prediction Markets

Once the Welfare Metric is defined by the LD module, the "beliefs" layer uses conditional prediction markets to evaluate specific policy proposals. The mechanism operates as follows 35:

When a policy proposal is submitted (e.g., "Launch a $1M grants program funded by the treasury"), the protocol automatically creates two conditional token markets.
Market A trades a token that pays out $1 if the proposal is adopted and the Welfare Metric is above a certain value X at a future date T, and $0 otherwise. The price in this market represents the market's collective prediction of the probability that the Welfare Metric will exceed X if the policy passes.
Market B trades a token that pays out $1 if the proposal is rejected and the Welfare Metric is above the same value X at the same future date T, and $0 otherwise. The price here represents the market's prediction of the outcome if the status quo is maintained.
Decision Rule: The markets remain open for a fixed period of trading. At the end of this period, the protocol compares the final prices. If the price in Market A is higher than the price in Market B, the proposal is automatically adopted and executed by the protocol's smart contracts. The market has effectively signaled its collective belief that the proposal is the superior path toward achieving the community's stated goals.

While prediction markets are powerful information aggregators, research has shown they are not entirely immune to manipulation, especially by well-funded actors who may wish to force a particular outcome for external reasons.43 Sophia's design includes several mechanisms to enhance market robustness:

Subsidized Liquidity: The protocol's treasury can be used to act as an automated market maker, providing a baseline level of liquidity to both sides of every market. This increases the "slippage" and makes it significantly more expensive for a single actor to manipulate the price away from the perceived true probability.
Reputation-Gated Trading: To prevent Sybil-based manipulation or influence from untrusted actors, access to larger trading limits within the prediction markets could be gated by a user's on-chain reputation score. This ensures that participants with a long history of positive engagement have a greater say than new, anonymous accounts.

3.4. The Adaptive Loop: A Direct Defense Against Goodhart's Law

The single most profound and challenging vulnerability of a pure futarchy is its susceptibility to Goodhart's Law, which states: "When a measure becomes a target, it ceases to be a good measure".12 Once a metric is targeted for optimization and reward, individuals will inevitably find ways to maximize the metric itself, often in ways that are counterproductive or detrimental to the actual, underlying goal the metric was supposed to represent.13

The classic example is the Soviet nail factory that, when given a target based on the
number of nails, produced thousands of tiny, useless nails. When the target was changed to the weight of nails, it produced a few giant, useless nails.48

In a futarchy, the Welfare Metric is the target. The prediction markets are a powerful optimization engine aimed squarely at this target. Over time, this engine will inevitably discover and reward policies that "teach to the test"—policies that are very good at increasing the number reported by the Welfare Metric, but which may harm the true, holistic health of the protocol in unmeasured ways.
Sophia's solution to this existential threat is to close the loop, creating a system of "Adaptive Futarchy." The key is to recognize that the problem is not the use of metrics, but the fixation on a single, static metric. The solution is to make the metric itself subject to continuous, deliberative governance.

The adaptive loop works as follows:

The prediction markets (the "beliefs" layer) act as an adversarial force, constantly searching for exploits and edge cases in the current definition of the Welfare Metric, W.
The community observes the real-world outcomes of the policies selected by the markets. Over time, they may notice a divergence between the rising value of W and their subjective experience of the protocol's health. For example, W might be increasing, but they perceive that the system is becoming less fair, more centralized, or more fragile.
This collective dissatisfaction can be channeled into a concrete governance action within the Liquid Democracy module (the "values" layer). A community member can submit a proposal to change the Welfare Metric from W to a new formula, W', which is designed to patch the observed exploit. For example, if the market has been favoring policies that increase transaction volume at the cost of extreme wealth inequality, W' might incorporate a Gini coefficient component to penalize inequality.
Because this is a "values" decision—a change in the fundamental definition of what the community is optimizing for—it is voted on by the LD module, not decided by the prediction markets.
If the proposal to adopt W' passes, the rules of the game change. The prediction markets are now re-tasked with a new mission: find the policies that best maximize the new, more nuanced metric, W'.

This creates a dynamic, adversarial, and ultimately collaborative process between the optimizing power of the market and the deliberative wisdom of the community. The market's relentless search for loopholes in the current ruleset serves to highlight the deficiencies in the community's definition of "good." The community, in turn, responds by periodically refining that definition. This adaptive loop makes the governance system anti-fragile. It doesn't assume a perfect metric can be found at the outset; instead, it assumes all metrics are flawed and builds in a mechanism for continuous learning and improvement.

Part IV: System Architecture and Implementation on a ZK-Rollup Framework

The theoretical constructs of the Sophia protocol—a global-scale UBI, a complex hybrid identity system, and a dynamic governance mechanism—place immense demands on the underlying technical infrastructure. To move from theory to a practical and viable implementation, the protocol must be built on a foundation that is secure, scalable, and cost-effective. This section details the architectural choice to build Sophia as a Layer 2 protocol on a Zero-Knowledge Rollup (ZK-Rollup) framework, and outlines the high-level smart contract structure.

4.1. The Scalability Imperative: Why Layer 1 is Insufficient

A system designed to serve a global user base will generate a colossal volume of transactions. The UBI component alone, if distributed daily to millions of users, would create a constant stream of micro-transactions. The mutual credit system involves numerous small-value exchanges. The governance layer adds voting, delegation changes, and continuous trading activity in its prediction markets.

Attempting to execute this transaction load directly on a Layer 1 (L1) blockchain like Ethereum would be completely infeasible. The limited block space and high demand for it would result in prohibitively expensive transaction fees (gas costs) and slow confirmation times. A UBI payment that costs more in fees than the payment itself is not viable, and a governance vote that takes minutes or hours to confirm is not practical. Therefore, a Layer 2 scaling solution is not an optimization for Sophia; it is a fundamental prerequisite for its existence.

4.2. The Choice of ZK-Rollups

Among the various Layer 2 scaling solutions, ZK-Rollups are uniquely suited to the specific requirements of the Sophia protocol. A ZK-Rollup works by bundling, or "rolling up," thousands of transactions off-chain in a Layer 2 environment. It then generates a single, succinct cryptographic validity proof (typically a ZK-SNARK or ZK-STARK) that mathematically proves the correctness of every single transaction in the batch. This small proof, along with a compressed summary of the transaction data, is then submitted to the Layer 1 chain for verification.49

This approach offers several critical advantages for Sophia over other scaling solutions, such as Optimistic Rollups:

Unconditional Security Guarantees: The core difference between ZK-Rollups and Optimistic Rollups lies in their security model. Optimistic Rollups assume transactions are valid and rely on a "fraud proof" system, where observers have a challenge period (often lasting a week) to submit proof of any invalid state transition.54 This results in long withdrawal times and a security model that depends on the vigilance of at least one honest actor. ZK-Rollups, by contrast, use validity proofs. A state transition on a ZK-Rollup is only accepted by the L1 contract if it is accompanied by a valid cryptographic proof of its correctness. This means that once a ZK-Rollup batch is finalized on L1, its transactions are as secure and irreversible as any L1 transaction. For a protocol managing a UBI and a financialized governance system, this level of mathematical certainty and fast finality is non-negotiable.49
Massive Scalability and Cost Reduction: By moving the computationally intensive work of transaction execution off-chain and only posting highly compressed data and a small proof on-chain, ZK-Rollups can achieve throughput increases of two to three orders of magnitude compared to the underlying L1. Transaction fees can be reduced by a factor of 100 or more.50 This is what makes the high-frequency, low-value transactions inherent in a demurrage-based UBI system economically feasible.
Inherent Privacy Capabilities: The underlying cryptographic primitive of ZK-Rollups is the zero-knowledge proof. This creates a powerful architectural synergy with the other components of the Sophia protocol. The same cryptographic tools and expertise required to build the rollup's core proving mechanism can be directly leveraged to implement the advanced privacy features of the identity and governance layers.

This deep integration of zero-knowledge cryptography at both the infrastructure and application levels makes Sophia a "ZK-native" protocol. Its most ambitious features—privacy-preserving biometric verification, selective disclosure of credentials, and potentially private voting—are not afterthoughts bolted onto a generic scaling solution. They are natural extensions of the core architectural choice, creating a unified, coherent, and privacy-preserving technological stack from the base layer all the way to the user-facing application. This synergy reduces development complexity, enhances overall security by relying on a consistent set of well-audited cryptographic components, and makes privacy a first-class citizen of the entire ecosystem.

4.3. High-Level Smart Contract Architecture

The Sophia protocol's implementation would be split between a set of minimal, highly secure contracts on the Layer 1 blockchain (e.g., Ethereum) and the main body of application logic deployed on the Layer 2 ZK-Rollup.

L1 Contracts (on Ethereum)

The L1 contracts serve as the trust anchor for the entire system. Their role is to be as simple and secure as possible, managing only the most critical functions:

Bridge Contract: This contract manages the depositing of assets (e.g., ETH or stablecoins) from L1 into the Sophia L2 and the processing of withdrawals from L2 back to L1. It locks assets on L1 when they are moved to L2 and releases them upon receipt of a valid withdrawal proof from the rollup.53
Verifier Contract: This is the core of the L1 security model. It contains the logic to verify the ZK validity proofs submitted by the L2 sequencer. It will only accept a new state update from the rollup if the accompanying proof is mathematically valid.53
State Contract: This contract stores the current cryptographic state root (a Merkle root) of the Sophia L2. Each time the Verifier Contract accepts a new valid proof, it updates this state root. This contract serves as the ultimate, indisputable source of truth for the state of the Sophia protocol.53

L2 Contracts (on the Sophia ZK-Rollup)

The vast majority of the protocol's logic resides on the fast, low-cost L2 environment. This is where all user interactions and application-specific computations occur:

Identity Registry: This suite of contracts manages the entire Proof of Personhood framework. It includes the Merkle tree of identity commitments, the logic for processing nullifiers to prevent double-spending of identity, the registry for Verifiable Credentials, and the smart contracts that manage the Web of Trust, including voucher staking and slashing.
Mutual Credit Engine: This contract implements the core economic logic of the protocol. It handles the periodic issuance of UBI to all verified identities, the rules for extending and settling mutual credit between users, and the automated application of the demurrage fee to all positive balances at each interval.
Liquid Democracy Module: This contract manages the "values" layer of governance. It stores the delegation graph, allowing users to delegate and revoke their voting power. It processes votes on proposals related to the Welfare Metric and other constitutional parameters, and it contains the logic for applying reputation-based weighting and delegation caps.
Futarchy Module: This contract manages the "beliefs" layer of governance. It is responsible for the automated creation of conditional prediction markets for each new policy proposal. It contains the logic for the automated market maker that provides baseline liquidity, and it executes the final decision rule by comparing market prices and triggering the adoption or rejection of the proposal.

This bifurcated architecture allows Sophia to leverage the unparalleled security and decentralization of a major L1 like Ethereum as its settlement and data availability layer, while executing its complex and high-throughput application logic in a scalable and cost-effective L2 environment.

Part V: A Critical Analysis of Failure Modes and Mitigation Strategies

A robust protocol is defined not only by its intended functionality but also by its resilience to unintended consequences and adversarial attacks. A comprehensive "pre-mortem" analysis is essential to identify potential failure modes and to embed mitigation strategies directly into the protocol's design. This section conducts such a critical analysis, examining the most significant risks across Sophia's economic, identity, and governance layers and detailing the mechanisms designed to counter them.

5.1. Economic System Failure

The most significant risk to the economic system is a crisis of confidence, potentially leading to a "death spiral." This could be triggered by an external shock or an internal vulnerability, causing participants to lose faith in the value of Sophia Credit (SC). A mass exodus to fiat currency would follow, causing the value of SC to hyperinflate and collapse, rendering the UBI worthless and destroying the internal economy.

Mitigation Strategies:
- Demurrage as an Inertial Damper: The demurrage mechanism, as detailed in Part I, provides a powerful, built-in defense against this scenario. In a typical currency collapse, the rational strategy is to hoard a more stable asset and dump the failing currency. Demurrage makes holding SC costly, creating a constant incentive for internal circulation even during a crisis. While it cannot prevent a determined exit, it acts as an inertial damper, discouraging panic-hoarding and encouraging participants to seek value within the network first.19
- Treasury Stabilization Fund: The protocol will maintain a treasury, funded by a small fee on activities that bridge to external economies (e.g., a fee on exchanging SC for fiat-backed stablecoins). This treasury, controlled by Sophia's governance, can act as a "market maker of last resort." During a crisis, it can be deployed to defend the value of SC by buying it on open markets, absorbing selling pressure and signaling a commitment to stability.
- Adaptive UBI Issuance: The rate of UBI issuance is not hard-coded but is a governable parameter. In response to severe inflationary pressure, the community can vote, via the governance process, to temporarily reduce or halt the issuance of new SC. This provides a crucial monetary policy lever to manage the money supply and restore confidence during periods of extreme volatility.

5.2. Identity System Compromise

The identity system's primary risk is a systemic exploit that allows for the large-scale creation of fraudulent, or Sybil, identities. This could occur through several vectors: a compromised biometric verifier manufacturer flooding the system with fake verifications, a breakthrough in AI that can reliably fool biometric liveness checks, or a large-scale, well-capitalized collusion attack that subverts the Web of Trust. A successful attack of this nature would be existential, as it would allow the attacker to claim a vast share of the UBI and hijack the governance process.

Mitigation Strategies:
- Defense-in-Depth via Hybridization: The multi-pillar identity framework is the primary defense. The pillars (biometric, social, credential-based) are designed to be as independent as possible. A compromise in the biometric system, for example, does not automatically grant an attacker full privileges. Governance could vote to temporarily disable the compromised pillar, increase the requirements for the other pillars (e.g., require more vouches), and rely on the remaining layers for security while a fix is developed. A systemic failure would require simultaneous, correlated compromises across multiple, distinct verification methods.
- Continuous Re-attestation: A Sophia identity is not granted in perpetuity. The protocol will require all participants to periodically re-attest their identity (e.g., annually or biennially). This process forces Sybil attackers to continually re-execute their exploit, increasing the chances of detection. It also serves to prune dead or abandoned accounts from the system, ensuring the UBI is directed only to active, living participants.
- Social Recovery Mechanisms: If an individual user's private keys are stolen or lost, they have not permanently lost their identity. The protocol will include a social recovery mechanism, where a user can call upon a quorum of their original vouchers (or other trusted members of their social graph) to attest to their identity and approve the rotation of their account to a new set of keys. This invalidates the compromised keys and secures the user's identity and assets.

5.3. Governance Capture

Despite the safeguards built into the Adaptive Futarchy model, the risk of governance capture by a wealthy and determined adversary remains. This could manifest as a "51% attack" on the Liquid Democracy module through vote-buying or coercion, or as a sustained manipulation of the prediction markets to pass malicious proposals that benefit the attacker at the expense of the commonwealth.

Mitigation Strategies:
- The Constitutional Circuit Breaker: The protocol's foundational rules will be codified in a "constitution" that is exceptionally difficult to amend. This constitution will enshrine a critical safety mechanism: an "emergency shutdown" or "governance halt." If a proposal is submitted that is deemed existentially threatening to the protocol—for example, a proposal to remove the demurrage fee, disable the PoP system, or seize treasury funds—a supermajority of voters (or a designated council of reputable guardians) can trigger a temporary halt to all on-chain governance. This "circuit breaker," inspired by similar emergency mechanisms in protocols like MakerDAO 8, freezes the system, giving the community time to coordinate an off-chain response, organize a counter-proposal, or, in the most extreme case, execute a hard fork to eject the attacker from the network.
- Radical Transparency and Monitoring: All governance activities—every vote cast, every delegation made, every trade in the prediction markets—are public and recorded immutably on-chain. This allows for constant, real-time monitoring by the community and by independent, third-party watchdog organizations. These watchdogs can develop sophisticated analytics to detect suspicious patterns of activity, such as coordinated vote-buying or market manipulation, and can alert the broader community, enabling a swift social and political response to a nascent capture attempt.

Conclusion

The Sophia protocol represents an ambitious attempt to synthesize lessons from economics, computer science, and political theory into a coherent and integrated framework for a decentralized digital commonwealth. It is founded on the recognition that the critical challenges of our digital age—structural economic inequality, the erosion of authentic identity, and the deficit of effective governance—are not independent problems to be solved in isolation. Rather, they form an interconnected trilemma, where a failure in one domain precipitates crises in the others.

Sophia's design is therefore holistic, architecting a series of virtuous cycles intended to create a resilient and equitable system.

Its economic model, built on a UBI and catalyzed by demurrage, is designed to counteract the wealth-concentrating force of r > g by ensuring broad-based distribution and a high velocity of internal exchange. It transforms the currency from a speculative asset into a pure medium of exchange, fostering a self-sustaining circular economy.
Its identity framework provides a robust and accessible solution to the Sybil problem. By creating a hybrid, multi-pillar Proof of Personhood system, it combines the scalability of privacy-preserving biometrics with the resilience of a socially-grounded Web of Trust and the flexibility of Verifiable Credentials. This creates a system of progressive trust that is more inclusive and resistant to single points of failure than any monolithic approach.
Its governance protocol, "Adaptive Futarchy," offers a novel solution to the challenge of collective decision-making. By separating votes on values from bets on beliefs, it leverages both democratic deliberation and the information-aggregating power of markets. Crucially, its built-in adaptive loop, which allows the community to govern the very metric the markets optimize, represents a structural defense against the existential threat of Goodhart's Law.

These three pillars are unified and made practical by an underlying architecture built on ZK-Rollups, which provide the necessary security, scalability, and privacy for a global-scale system. The protocol is not presented as a perfect or final solution, but as a robust, adaptable, and thoughtfully designed foundation. The comprehensive analysis of its potential failure modes and the inclusion of specific mitigation strategies—from economic circuit breakers to defense-in-depth for identity—reflect a pragmatic understanding of the profound challenges involved.

Ultimately, the Sophia protocol is a blueprint for a digital society that is not only decentralized in its technology but also democratic in its governance and distributive in its economy. It is an attempt to build a system with the wisdom to learn, the resilience to endure, and the commitment to place the unique, living human being at the center of its universe.

Frequently Asked Questions

General Questions

Q: What is the Sophia Protocol?

A: Think of Sophia as a blueprint for building a fairer, more democratic digital society. It's a set of rules for a new kind of online system that combines three key ideas:

A Fair Economy: A money system designed for spending and sharing, not just for getting rich.
Real Identity: A secure way to prove you are a unique human online, without giving up your privacy.
Smart Governance: A way for the community to make decisions together, where the best ideas win.

The goal is to create a digital world that is owned and operated by its users, not by a single company or government.

Q: What is the main problem Sophia is trying to solve?

A: Today's online world has a few big problems. Wealth tends to get concentrated in the hands of a few (like big tech companies). It's hard to know who is a real person and who is a bot. And decisions are usually made from the top down. Sophia tries to solve these problems by creating a system that is naturally more balanced, secure, and democratic.

Q: Is this another cryptocurrency like Bitcoin?

A: No, not really. While it uses similar technology (like a blockchain), its purpose is completely different. Bitcoin is often treated as a digital asset to buy and hold, hoping its value goes up. Sophia's currency is designed for the exact opposite: to be actively used and circulated for buying and selling goods and services. Its goal is to power an economy, not to be a speculative investment.

Q: Is this just for online communities, or can it be used in the real world?

A: The goal is absolutely for it to be used in the real world. A neighborhood, a co-op, or even an entire city could adopt the protocol to manage its local economy, public services, and civic decision-making. The digital layer is just the tool; the real application is in empowering real-world communities.

The Economy: Fair Money

Q: How does the money system work?

A: Sophia uses a "mutual credit" system. This means money is created when people trade. Instead of a central bank printing money, when you provide a service to someone, your account balance goes up, and theirs goes down. This ensures there is always enough money in the system to support the community's needs.

Q: What gives the credits their value? Why would anyone accept them?

A: The value of a credit comes directly from the goods and services offered by the community. A credit is valuable because you can use it to buy a loaf of bread, get a haircut, or pay for a programming lesson from someone else in the network. Its value is based on the real, productive capacity of the people who use it, not on speculation.

Q: If Universal Basic Income (UBI) is always creating new credit, what stops massive inflation?

A: This is a crucial question. The system has two main counter-balances. First, Demurrage (the holding fee) constantly removes a small amount of credit from the system, preventing infinite accumulation. Second, the UBI issuance rate can be adjusted by community governance. If the economy is growing quickly with many new goods and services, the UBI might be increased to match. If it's stagnant, the rate could be lowered. It's a dynamic system managed by the community to keep the currency stable.

Q: I read about "demurrage." What is that?

A: Demurrage is a small fee on money that is sitting still. Think of it like a "hot potato" effect—it encourages you to spend or use your credits rather than just holding onto them. This keeps money flowing through the community, creating more business for everyone and preventing the kind of hoarding that can stall an economy.

Q: Can I exchange these credits for regular money like Dollars or Euros?

A: Yes, it's possible. While the system is designed to be a self-sustaining internal economy, communities can create "gateways" that allow members to buy and sell credits for external currencies. These would function like community-run exchanges, allowing for seamless interaction with the traditional economy.

Q: How can an economy function without interest? How do people get loans?

A: Your ability to have a negative balance in the mutual credit system is essentially a community-backed, interest-free loan. For larger needs, like starting a business, the community could form groups (DAOs) to pool resources and vote to grant a larger credit limit to a specific project. Your reputation for fulfilling obligations would be the most important factor in getting this kind of support, not how much money you already have.

Work, Business & Property

Q: How would I get a salary?

A: The idea of a single "salary" changes a bit. Instead of one employer, you can earn income from many sources. Every time you sell a product, perform a service, or complete a freelance task for someone in the network, you are paid directly in credits. A company could still exist and agree to pay you a regular, fixed amount of credit for your work, which would look very similar to a traditional salary.

Q: How does investment work if the currency is designed not to be hoarded?

A: The system encourages productive investment rather than financial speculation. Instead of buying a currency and hoping its price goes up, you would invest your credits directly into projects you believe in—like funding a local farm, a new software application, or an artist's next project. Your "return" would be a share of that project's future earnings, which you would then be encouraged to spend back into the economy. The goal is to fund real value, not just to accumulate idle wealth.

Q: How is ownership of physical property (like a house or car) managed?

A: The network's public ledger can act as a universal registry for property. Your ownership of a house could be represented by a unique digital token (like an NFT) in your secure digital wallet. Selling the house would be as simple and secure as transferring that token to the buyer, with the transfer being recorded permanently and publicly on the ledger.

Identity & Security

Q: How do you prove you're a real person online?

A: Sophia uses a hybrid approach with multiple options. The main ways are:

Private Biometrics: You can use a special device to scan something unique, like your iris. The system only confirms you are a unique human; it never saves or shares your actual biometric data.
Web of Trust: You can be "vouched for" by people who are already verified members of the network.

This multi-layered system makes it very hard for bots or scammers to create fake accounts.

Q: Will my personal data be safe?

A: Yes. Privacy is a core principle of Sophia. It uses advanced cryptography called "Zero-Knowledge Proofs." This technology lets you prove something is true without revealing the information itself. For example, you could prove you are over 18 without ever revealing your actual birthdate. You are always in control of your data.

Q: What happens if I lose my phone or password? Is my identity and money gone forever?

A: The protocol includes plans for "social recovery." Instead of a password, you would pre-select a few trusted friends or family members (guardians). If you lose access to your account, you can reach out to them. If a majority of your chosen guardians confirm your identity, the system will grant you access to your account again. This is much safer than relying on a single password.

Q: How is the network protected from powerful hackers or even governments?

A: Security comes from decentralization. Because the ledger is stored on thousands of computers around the world, there is no single point of attack. To alter the record, an attacker would need to control a massive portion of the network's reputation and stake simultaneously, which is designed to be economically and practically impossible.

Governance & Community

Q: Who is in charge of the Sophia network?

A: The community is in charge. There is no CEO or central authority. Sophia uses a special governance system where everyone gets to participate in making the rules.

Q: How are decisions made?

A: It's a two-part process:

Vote on Values: The community votes on big picture goals (e.g., "What is most important to us?").
Bet on Beliefs: Once a goal is set, people use prediction markets to bet on which proposal is most likely to succeed. The policy with the best odds is automatically chosen.

Q: How are disputes resolved without lawyers and courts?

A: The network would have a reputation-based arbitration system. If two people have a dispute, they can agree to have it reviewed by a neutral third party with a high "mediation" reputation score. The arbitrator's decision could be automatically enforced by a smart contract, and failing to comply would publicly damage one's reputation.

Q: What about public services? Are there taxes?

A: There are no "taxes" in the traditional sense. Instead, the community can vote to apply a very small, automatic fee to all transactions. These fees go into a public fund, which the community then votes on how to spend—whether it's for improving the network's code, funding public art, or supporting environmental projects.
