Sustainable GameFi Economics: Asset Sinks, NFT Utility, and P2E Viability
Preventing GameFi Collapse: NFT Utility, Asset Sinks, and Economic Viability
Every developer and investor in Web3 gaming already feels the pulse-quickening anxiety that comes from watching yet another project implode under its own inflationary pressure, collapsing into the familiar Ponzi spiral everyone pretends they didn’t see coming.
The fear is justified: without strict token velocity control, real value accrual, properly engineered in-game utility, and ecosystem funding that doesn’t depend on extracting liquidity from new players, there is no economic sustainability to speak of.
The great token printing machine never sleeps, and the only real defenses against it are painful to implement: robust Asset Sinks, meaningful Burn Mechanics, and consistent Token Inflation Control baked directly into the system architecture.
The industry keeps repeating the same mistakes with governance tokens, slashing risk mismanagement, mispriced cryptocurrency asset classes, and shallow player incentives, but the mission here is to break that cycle before it consumes the next generation of play-to-earn economies.
Token Inflation Control in GameFi (The Dual Token Dilemma)
The panic around token dumping is not some abstract theoretical threat; it is the single most common failure mode in GameFi, and everyone who has spent more than a month analyzing these economies knows exactly why.
Once players receive tokens as rewards, the system inherits instant inflationary pressure, and unless the underlying framework is engineered to maintain value accrual, the selling cascade begins. The Dual Token Dilemma appears to be the industry’s preferred answer: one governance token, one utility token, two diverging token velocities, and a fragile expectation that players will not immediately liquidate the reward asset. But aligning player incentives with long-term holders is a brutal challenge.
Governance tokens demand scarcity; utility tokens demand emission; both demand equilibrium that most projects never achieve.
None of this works unless the economy establishes an unavoidable, high-friction structure that reduces circulating supply with precision, not hope.
Analyzing GameFi Project Tokenomics for Long-Term Viability
Evaluating whether a GameFi project can survive beyond its first hype cycle requires focusing on the real mechanical weak points: how fast tokens can be sold, how steeply vesting schedules unlock for founders, and how aggressively staking rewards compensate for the expanding circulating supply. A project without a strict vesting schedule inevitably triggers a supply shock once early investors regain liquidity, crushing any value accrual the ecosystem tried to build.
Staking incentives slow the bleeding by locking governance tokens, but they only work when emissions are mathematically sustainable rather than celebratory giveaways. Liquidity mining risks remain painfully high if the system assumes that players will voluntarily hold a reward token designed for spending.
This is where most dual-token models fail: the utility token leaks value relentlessly because players treat it as an exit mechanism rather than a functional resource. The only real solution requires embedding unavoidable sinks that force tokens back into the system and permanently remove them through deflationary mechanics.
Question: Why does the dual-token model often fail projects? The failure stems from the leakage problem, where the reward token is structurally designed for spending but ends up being sold instantly for profit, creating permanent sell-side pressure that inflates supply.
The economically viable mitigation strategy requires forcing the utility token into expensive, irreversible sinks, rebalancing token velocity while ensuring that players who engage with the system actually reduce circulating supply rather than add to it.
Question: How do revenue generation models impact ecosystem funding? Sustainable ecosystems rely on external revenue streams such as NFT royalties, marketplace fees, land sales, and protocol-level charges that continuously inject non-speculative capital. Without these external inflows supporting the token’s value, the system becomes dependent on new player liquidity, transforming the economy into a slow-motion collapse masked as growth.
Designing NFT Utility in Web3 Gaming (Asset Sinks & Burn)
The entire premise of NFT integration in GameFi has been misunderstood for years, mostly because projects keep treating NFTs like decorative collectibles instead of economic instruments designed to counteract relentless inflationary pressure and token velocity spikes. When NFT utility is shallow, players disengage, economic sustainability collapses, and the system is left relying on speculative cryptocurrency asset classes rather than actual in-game utility.
The only rational approach is to design NFTs as controlled deflation engines, where every upgrade, fusion, repair, and progression step consumes resources and pushes value accrual upward.
Asset Sinks become mandatory architecture, not optional cosmetics, because a free-to-play model relying on non-consumable NFTs is already structurally doomed. Investors evaluating Web3 gaming must identify whether NFT mechanics enforce irreversible consumption, rapid value cycling, and systemic load reduction.
Without those constraints, the economy behaves like a leaking bucket pretending to be a financial ecosystem.
NFT Asset Sinks and Burn Mechanisms Explained
Asset Sinks serve one brutal but necessary purpose: they permanently remove NFTs or tokens from circulation, ensuring that long-term viability does not depend on a growing influx of new buyers. The most effective sinks are the ones that players cannot avoid. Permanent Upgrade Systems consume older NFTs to produce stronger versions, creating natural scarcity.
Forging Costs require players to spend large amounts of tokens or materials, burning them in the process. Repair Mechanics, when tuned correctly, force continuous spending instead of one-time purchases. Breeding Fees, if priced accurately, counterbalance inflation by removing more value than they generate.
These mechanisms work only when the cost curve escalates with progression, preventing late-game stagnation. Weak sinks—temporary rentals, cosmetic-only access, or low-fee crafting—fail because they allow players to enjoy progression without contributing to deflation, undermining all attempts at true game design complexity.
Question: What is the difference between cosmetic utility and essential utility? Cosmetic utility offers superficial changes that do not influence competitive performance, so players ignore these sinks unless prices are trivial.
Essential utility is directly tied to advancement, power scaling, and economic progression. When an upgrade determines win probability or income potential, players engage repeatedly, injecting continuous deflationary pressure back into the economy. Projects that rely on cosmetic utility misprice their economic model from day one.
| Mechanism | Impact | Project Viability |
|---|---|---|
| Permanent Upgrade | Deflationary | High |
| Forging Cost | Deflationary | Moderate-High |
| High Repair Cycle | Deflationary | Moderate |
| Breeding Fee | Mixed | Variable |
| Cosmetic Rental | Inflationary | Low |
| Time-Limited Cosmetic | Inflationary | Very Low |
Comparing Web3 Gaming Layer-1s and Layer-2s Scalability
The economic anxiety surrounding infrastructure choices is far more serious than most developers admit, because the underlying blockchain defines transaction cost behavior, player incentives, and scalability limits that shape the entire financial loop. High gas fees on certain Layer-1s destroy micro-transaction viability, suffocating value accrual and accelerating liquidity mining risks as users avoid interactions that would otherwise stabilize token velocity.
Networks like Solana offer low-fee throughput at the cost of occasional congestion, while Ronin and ImmutableX specialize in gaming-specific scalability that enables high-frequency actions without eroding player incentives. Layer-2 rollups solve cost issues but introduce new slashing risk vectors, especially when bridging assets between layers.
Smart contract vulnerabilities on bridges represent catastrophic failure points capable of draining liquidity instantly. Economic sustainability depends on choosing an infrastructure that minimizes friction, maximizes transactional density, and avoids turning progression mechanics into a financial burden players refuse to pay.
Question: What is the greatest technical risk to liquidity mining risks in GameFi? The largest threat is cross-layer asset exposure. Bridging reward tokens or NFTs between L1 and L2 layers introduces a compounded smart contract risk surface. Exploits drain reserves, distort supply, and destabilize token value faster than any inflation model.
The only mitigation is minimizing bridge dependency and ensuring that emissions and sinks occur on the same execution layer.
Token Inflation Control in GameFi (The Dual Token Dilemma) — Extended Strategic Analysis
When developers attempt to stabilize a reward-driven system without acknowledging the crushing force of inflationary pressure, the outcome is almost predetermined. Every emitted token adds weight to circulating supply, accelerating token velocity until the economy snaps under its own imbalance. This phase is where even serious investors miscalculate, assuming that governance tokens will somehow maintain value accrual despite sloppy incentive engineering.
The Dual Token Dilemma becomes a battlefield of conflicting priorities: governance token scarcity versus utility token emission. Projects often compensate for early liquidity mining risks with over-aggressive APRs, hoping players will voluntarily compound instead of selling. But hope is not a mechanism; it is a liability.
Without disciplined economic sustainability, vesting control, strict emission curves, and unavoidable utility sinks, the entire reward system mutates into an exit environment where players cash out faster than new liquidity enters. That structural panic explains why even ambitious systems decay at alarming speed.
Analyzing GameFi Project Tokenomics for Long-Term Viability — Advanced Considerations
Real due diligence for long-term viability requires tearing into the architecture, not just reading a whitepaper soaked in optimistic jargon. The first priority is determining whether the emission model mathematically aligns with projected user growth.
Most projects assume exponential onboarding while emissions remain linear or exponential, guaranteeing oversupply. The second priority is validating the vesting discipline for founders, advisors, and seed investors. If early allocations unlock during a market downturn, circulating supply faces a brutal shock that overwhelms any value accrual mechanism.
The third priority is analyzing staking design: is staking absorbing supply or simply redistributing inflation? A staking system that emits more than it locks contributes to collapse. Players often mistake high APRs as opportunity, but developers must interpret them as structural warnings.
Finally, an investor must review how the ecosystem funding mechanism injects outside liquidity. A system dependent exclusively on player inputs replicates the same unsustainable loops that already destroyed dozens of GameFi economies.
Question: Why do even well-designed reward systems collapse? They collapse because player incentives are misaligned with long-term token retention. When rewards exceed ecosystem revenue, utility tokens become extraction vectors rather than functional assets.
The circulation rate spikes, liquidity pools saturate with sell pressure, and governance tokens lose their stability anchor. Without binding deflationary mechanisms to reduce supply, reward systems become self-terminating cycles.
Question: How can staking systems prevent supply overload? They can prevent overload only when staking is tied to strict scarcity mechanics. Locking periods must extend through emission waves, penalties must discourage early exits, and reward rates must decline algorithmically.
Staking must behave like a pressure valve, not an inflation amplifier. When staking becomes an entitlement rather than a containment tool, supply spirals out of control.
Designing NFT Utility in Web3 Gaming (Asset Sinks & Burn) — High-Pressure Economic Design
The narrative around NFT utility has been polluted by superficial implementations that treat NFTs as speculative trophies instead of economic levers engineered to throttle inflation and reduce liquidity leakage. To build a sustainable system, utility must extend far beyond cosmetic skins and into core progression loops where every player interaction consumes resources.
Asset Sinks must be unavoidable, strategically expensive, and deeply integrated into game design complexity. They counteract the runaway inflation caused by reward emissions, and without them, the economy shifts into extraction mode almost instantly. Tokens with no sinks behave like volatile coupons; NFTs with no burn mechanisms become inventory clutter.
Economic sustainability demands that players continuously reinvest into the system, willingly or through necessity, to maintain competitiveness. Unlike traditional free-to-play models that monetize convenience, GameFi must monetize survival, progression, and competitive pressure.
If players can progress indefinitely without sacrificing assets, the system is already structurally broken.
NFT Asset Sinks and Burn Mechanisms Explained — Advanced Breakdown
Burn mechanics only function when they permanently remove value, not when they delay liquidity. An upgrade that consumes an NFT reduces long-term supply and strengthens value accrual for remaining holders. A forging system that burns tokens introduces strategic depth.
A repair loop that scales with item rarity forces veteran players to contribute disproportionately more deflation than newcomers. A breeding mechanic priced below its output value becomes an inflation engine; priced above it, breeding stabilizes supply. The distinction is subtle but decisive. Ineffective sinks mislead developers into believing they’ve solved inflation, but cosmetic-only sinks cannot counteract a reward-driven model.
The true measure is economic inevitability: players must face decisions where burning tokens or NFTs is the optimal or required action, not a polite suggestion from designers.
| Mechanism | Impact | Project Viability |
|---|---|---|
| High-Rarity Fusion Burn | Strong Deflation | High |
| Scaling Repair Costs | Moderate Deflation | Medium |
| Token-Heavy Forging | Variable Deflation | Medium-High |
| Low-Cost Breeding | Inflationary | Low |
| Non-Consumable Cosmetic Skins | Neutral | Very Low |
Comparing Web3 Gaming Layer-1s and Layer-2s Scalability — Deep Technical Evaluation
The infrastructure layer is not a branding choice; it is the structural backbone that determines how efficiently a GameFi economy handles transaction load, progression loops, and micro-interactions that fuel value accrual. A blockchain with high gas fees throttles player incentives instantly because every action—crafting, repairing, upgrading, trading—feels like a punishment.
That economic suffocation accelerates token velocity spikes, collapses NFT turnover, and pushes the ecosystem toward stagnation. Layer-1 chains like Solana and specialized networks like Ronin deliver high throughput and low-fee execution designed for heavy in-game utility cycles. Layer-2 rollups extend this efficiency by offloading congestion, but introduce a different threat surface through bridging, slashing risk, and settlement delays. Game-specific blockchain scalability demands low-friction finality, predictable costs, and seamless liquidity flows.
When infrastructure becomes unreliable or expensive, players disengage, liquidity dries up, and even the most mathematically balanced tokenomics crumble under abandoned activity loops.
Question: What is the greatest technical risk to liquidity mining risks in GameFi? The answer is the systemic fragility created by multi-layer bridging. When a project emits on L2 but settles on L1, every bridge becomes a pressure point where exploits, freezes, or liquidity drains can annihilate reserves. A compromised bridge triggers asymmetric supply distribution, wrecking token velocity and destabilizing pools. Minimizing cross-layer dependencies is not optional—it is fundamental economic risk management.
| Criterion | Ideal Answer | Risk Metric |
|---|---|---|
| Defined Burn Mechanism | Permanent and Mandatory | Low Risk |
| Inflation Rate Structure | Hard-Capped or Algorithmic | Low Risk |
| Primary Asset Sink | Progression-Linked and Expensive | Low-Medium |
| Staking Emission Curve | Declining, Non-Inflationary | Medium |
| Vesting Schedule Enforcement | Strict, Multi-Year | Low Risk |
| External Revenue Flow | Consistent and Non-Speculative | Low Risk |
| Bridge Exposure | Minimal or Controlled | High Risk if Excessive |
Strategic Fail-Safes for Preventing Economic Collapse in GameFi
At this stage of industry maturity, it is impossible to pretend that collapses come from “unpredictable market conditions.” They arise from predictable structural failures: oversupply, weak sinks, misaligned incentives, unmanaged token velocity, and reward systems that depend on endless liquidity injection from new players.
Strategic Fail-Safes exist, but developers rarely implement them with discipline. A stable system demands externally sourced liquidity, mandatory deflation, and economic throttles that decelerate supply growth during player surges. Ecosystem funding must rely on costs tied to progression, not on speculative NFT presales that introduce long-term liability.
The entire architecture must assume that players will extract value aggressively; survival depends on mechanisms that counterbalance extraction with enforced reinvestment. Without these safeguards, any tokenomics model—dual-token, single-token, hybrid—inevitably collapses once emissions exceed economic throughput and the system transitions from sustainable circulation to runaway leakage.
Long-Term Ecosystem Stabilization Techniques
Creating a long-lived GameFi ecosystem means engineering counterforces that continuously absorb inflation and reduce sell pressure without relying on artificial hype. One stabilization technique involves dynamic emission scaling, where reward output automatically decreases as token velocity rises. Another approach ties progression requirements directly to circulating supply, making upgrades or repairs proportionally more expensive as inflation increases.
Liquidity reserves must be algorithmically fed by external revenue rather than internal recycling, because internal recycling amplifies systemic fragility. Governance tokens require strict scarcity enforcement, achieved through multi-year vesting, slashing penalties, and controlled staking access. Utility tokens must flow through irreversible sinks that neutralize extraction behavior.
A self-correcting GameFi economy is not a myth—it is a structure where every spike in activity triggers balancing forces that reduce oversupply, increase burn, and push the system back to equilibrium. Without this dynamic counterweight, tokenomics become static, brittle, and doomed.
Question: Why do stabilization systems often fail despite good design? They fail because developers underestimate player optimization behavior. Players exploit every inefficiency, accelerating inflation beyond projected models.
Stabilization requires systems that cannot be bypassed—mandatory burns, non-negotiable progression costs, and dynamically enforced scarcity calibrated to real-time metrics.
Advanced Sustainability Frameworks for High-Load GameFi Economies
Building a GameFi economy that can withstand prolonged user activity requires more than clever tokenomics diagrams or optimistic projections; it demands a structural framework engineered to absorb volatility, redistribute pressure, and maintain economic sustainability under stress conditions.
The core challenge is that reward-based systems inherently push token velocity upward while injecting inflationary pressure into every progression loop, and without counterbalancing forces, this pressure compounds until collapse. High-load ecosystems must treat every transaction—crafting, trading, upgrading, repairing—as a regulatory event that influences supply.
When rewards inflate faster than sinks consume, value accrual dissipates. When players extract more than they reinvest, circulation decays. Economic architecture must therefore behave like a living system, adjusting to user behavior, absorbing liquidity shocks, and dynamically shaping incentives to maintain scalable deflation.
Without these automated controls, even the most sophisticated models degrade into chaotic, self-defeating loops under real-world usage.
Dynamic Emission Control and Automated Deflation Models
A robust sustainability framework begins with dynamic emission control, where reward output is algorithmically linked to real-time economic performance indicators such as circulating supply, liquidity depth, and activity velocity. Emissions must contract during periods of high extraction and expand only when sinks outweigh output.
Automated deflation models reinforce this by tying burn intensity to system health. When token velocity spikes, burn rates should automatically increase through more expensive upgrades, higher repair fees, or steeper forging requirements. These mechanisms prevent runaway inflation by redirecting user activity back into consumption.
Automated price oracles can also adjust crafting or breeding costs based on market conditions, ensuring players cannot exploit fixed-rate sinks during volatile phases. Liquidity mining risks decrease when emissions correlate directly with economic throughput rather than arbitrary reward schedules.
Tokenomics cease being static rules; they become adaptive constraints that reshape player incentives as conditions shift.
Question: What differentiates effective adaptive economics from reactive patching? Adaptive systems adjust automatically before failures occur, while reactive patching attempts to fix damage after the economy has already broken.
Adaptive economics ties emissions, burns, and progression costs to measurable metrics, preventing catastrophic oversupply before it escalates.
Reactive patching relies on manual adjustments that arrive too late, allowing players to exploit flaws for weeks or months.
High-Pressure Progression Loops and Reinforced Value Accrual
For an economy to maintain structural integrity, progression loops must reinforce value accrual rather than dilute it. Every advancement step—skill increase, gear improvement, territory upgrade—must require proportional economic contribution that removes tokens or NFTs from circulation.
A progression loop that does not consume value is a disguised subsidy that accelerates inflation. Reinforced progression loops convert player motivation into controlled deflation. When advancement forces players to burn resources, the system channels activity into equilibrium rather than excess.
Developers often underestimate the importance of aligning player incentives with economic necessity; if progression does not require constant reinvestment, the ecosystem becomes top-heavy, dominated by players who stop contributing to sinks.
This imbalance destroys sustainability by shifting consumption pressure to new users. A well-designed loop requires veterans to carry the highest burn load, ensuring value accrual remains stable even as user numbers fluctuate.
Designing Pressure-Based Upgrades and Competitive Sinks
Pressure-based upgrades represent the backbone of sustainable GameFi economies. These upgrades must introduce escalating costs that scale with player power, ensuring top-tier players contribute disproportionately to burn intensity. Competitive sinks amplify this by forcing players to consume tokens or NFTs to remain viable in high-level play.
Tournament entry fees, territory maintenance, seasonal resets, and consumable power boosts are all mechanisms that enforce ongoing reinvestment. The objective is not to punish players but to ensure that economic throughput is maintained under competitive load. Without competitive sinks, high-end players become net extractors, draining liquidity through rewards while contributing little.
Properly engineered, pressure-based sinks stabilize value, reduce circulating supply, and throttle destructive token velocity. The economic model becomes a cycle where ambition drives deflation.
Question: Why do high-level players destabilize weak economies? Because they extract disproportionately more rewards than they consume. Without scalable sinks, top-tier users accumulate wealth, dump excess tokens, and trigger cascading inflation. Strong economies ensure that competitive pressure forces veteran players to burn more than they earn, maintaining balance.
How Regulatory Arbitrage Shapes Token Velocity and Creates Distorted Market Incentives
Regulatory arbitrage operates as an invisible engine behind token velocity spikes, and understanding this mechanism is critical for deciphering why many ecosystems behave irrationally despite their supposed decentralization. When projects exploit jurisdictional loopholes, they often accelerate token distribution schedules, introduce soft-KYC mechanisms, or push pseudo-compliance frameworks designed solely to create a façade of legitimacy.
This artificially lowers friction for speculative actors and increases short-cycle churn, feeding high-frequency liquidity rotations instead of long-horizon network participation. The irony is that the more aggressively teams chase “regulatory flexibility,” the more they inadvertently nurture environments where genuine utility is sidelined and wash-trade liquidity becomes the dominant economic force. Token velocity ceases to be a metric of adoption and mutates into a signal of structural fragility, revealing how little intrinsic demand the token actually commands.
Arbitrage-driven ecosystems often show identical behavioral patterns: short-duration retention curves, inflated staking APYs masking supply-side sell pressure, and reliance on cross-chain wrappers to distribute regulatory risk rather than technical value. As a result, token holders unknowingly finance a machine optimized for compliance evasion rather than sustainable growth, while the foundational incentives push treasury managers to prioritize speed over stability, reinforcing a cycle that collapses as soon as external liquidity dries up.
Wrong vs Right: Preventing Economic Collapse
The difference between a sustainable ecosystem and a doomed one often lies in predictable design choices. Recognizing common failure modes allows developers and investors to apply strategic fail-safes before economic collapse becomes inevitable. The urgency is clear: assuming that player behavior is rational is the first mistake; a sustainable model assumes aggression and designs against it.
- Incorrect: Using low-cost cosmetic NFTs as the primary Asset Sink. Outcome: Players ignore cosmetic sinks, and token velocity spikes because rewards have nowhere to go but the open market.
- Correct: Implementing an expensive, progression-linked fusion mechanic that requires burning multiple lower-tier NFTs to produce a high-tier asset. Outcome: Forces players to reinvest and permanently removes supply, reinforcing value accrual through engineered scarcity.
- Incorrect: Setting a fixed, high staking APR regardless of active user numbers or external revenue flow. Outcome: Rewards become purely inflationary, consuming ecosystem funding and accelerating the eventual slashing risk when the treasury runs dry.
- Correct: Using Dynamic Emission Scaling tied directly to the ratio of tokens burned vs. tokens emitted. Outcome: The system automatically throttles inflationary pressure during high-activity extraction periods, ensuring economic sustainability is reactive and not passive.
These examples stress that survival depends on mechanisms that cannot be bypassed, ensuring player incentives align with deflationary mechanics, turning extraction into reinvestment through necessity.
Glossary of Advanced GameFi Economics
Navigating sustainable GameFi requires a precise vocabulary. The following terms are essential for evaluating project viability and risk in the cryptocurrency asset classes:
- Asset Sinks: Mechanisms (upgrades, forging) that force the permanent consumption of NFTs or tokens, counteracting inflation by reducing circulating supply.
- Token Velocity: The rate at which a token changes hands. High velocity in a utility token is often a sign of quick profit-taking and accelerating inflationary pressure.
- Value Accrual: The process by which the token or asset gains and retains intrinsic worth, usually tied to governance tokens or essential NFT utility, rather than pure speculation.
- Vesting Schedule: A legally binding timeline dictating when allocated tokens (for founders/investors) unlock. Poor vesting leads to catastrophic supply shocks.
- Slashing Risk: The economic penalty (loss of staked funds) imposed on validators or stakers for bad behavior. In GameFi, it can refer to risks associated with bridging or L2 security.
Why Tokenomic Models Collapse Without Elastic Demand Curves and Macro-Responsive Supply Mechanics
Most tokenomic architectures fail because they are built on static assumptions in a dynamic environment, ignoring the necessity of elastic demand curves and macro-responsive supply behaviors. Projects typically introduce fixed emission schedules, naive deflation narratives, or overly rigid staking lockups that assume infinite buyer appetite.
However, without an elastic mechanism that adjusts issuance, burn pressure, or participation rewards when macro liquidity shifts, the token economy becomes brittle.
During liquidity contractions—precisely when flexible systems are needed—these rigid models amplify volatility, triggering mass unstaking, cascading sell-offs, and treasury depletion.
The absence of macro-aware supply throttling is the primary reason tokens with initially strong momentum abruptly implode once market conditions deviate even slightly from their launch assumptions.
Elasticity is not a luxury but a prerequisite: demand curves must adapt to user growth stages, while supply mechanics must adjust automatically to risk-off cycles, miner/validator concentration, and velocity anomalies.
Without these stabilizers, ecosystems depend entirely on speculative inflows, turning their economics into a delayed-failure model disguised as innovation.
The uncomfortable truth is that many projects collapse not from external shocks but from internal design flaws—specifically, their inability to respond dynamically to macroeconomic pressure, which exposes the hollowness of their value proposition and reveals the absence of genuine utility-driven equilibrium forces.
