The digital advertising industry stands at a precipice. Decades of growth have culminated in a deeply flawed ecosystem, characterized by consolidation of power into proprietary walled gardens, monopolistic and anti-competitive behavior, systemic opacity, and rampant fraud in an attempt to exploit user data across the web, mobile apps, and streaming television. This market, valued at over $700 billion globally, is now facing a crisis of confidence. Advertisers question the efficacy of their spend, publishers struggle with diminishing returns, and users are increasingly aware and resentful of their role as the product. This fundamental tension has created an unprecedented strategic opening for a new foundational standard that can rebuild the industry on the principles of transparency, efficiency, and user control.

Enter Unwalled, a new project designed to seize this opportunity. The project's vision is to create a decentralized, permissionless ad-tech ecosystem by implementing new, open standards that allow for high-frequency, low-cost advertising transactions. We have deconstructed the current ad-tech battlefield, and mobilized around the strategic vulnerabilities of incumbent players whose versions of "transparency" are commercially motivated constructs designed to reinforce their market dominance.

In contrast, Unwalled offers a new paradigm built on three pillars. First, it provides a radically transparent, open-source advertising standard that serves as a neutral counterweight to closed, proprietary systems. Second, it is built upon a foundation of Decentralized Identity (DID), leveraging the high-performance settlement and identity layer Keeta ($KTA) to transform the ad supply chain into a "truth layer" where every participant and transaction is cryptographically verifiable. The identity framework is a critical hedge against an internet increasingly flooded with AI bots, ensuring that engagement is verifiably human, mirroring similar financial KYC requirements. Third, it establishes a new Value Exchange Standard, creating a fair and generative micro-economy where users are compensated for their attention and consented data.

This strategic rearchitecture of the advertising ecosystem is encapsulated by the name Unwalled. Together we’ll dismantle the walled gardens that currently dominate the digital landscape, prevent new manifestations of the same antipattern and build the foundational network for a fairer, more efficient, and verifiably true open internet.

Strategy

The contemporary programmatic advertising ecosystem is a paradox. It was founded on the promise of an open, efficient, and democratic marketplace for digital media, yet it has evolved into a system plagued by opacity, inefficiency, and the centralizing gravity of a few dominant platforms. Understanding the deep-seated tensions within this market is the first step in articulating the urgent need for a new foundational standard. The current landscape is not merely ripe for disruption; it is actively demanding a solution that can resolve its core contradictions. This section dissects the failures of the incumbent model, analyzes the proven success of open-source interventions as a market corrective, and establishes the clear mandate for a neutral, verifiable advertising standard.

Walled Gardens and New Threats

The core conflict in modern programmatic advertising is the chasm between its theoretical promise and its operational reality. Advertisers are confronted with a "paradox of choice," navigating a complex and convoluted supply chain where a significant portion of their budget is consumed by an "ad tech tax" before ever reaching the publisher. This value extraction is a direct result of obscured auction mechanics, rampant bid duplication, and a general lack of transparency that erodes trust and value for both buyers and sellers. Even when a platform with best intentions tries to push the boundaries of what is possible their innovation is twisted into controversy or the proposals get stalled at the bureau (IAB). The market's response has been a broad, industry-wide push for Supply Path Optimization (SPO), a movement dedicated to simplifying the ad transaction and demanding greater accountability from every intermediary.

No single company has capitalized on this movement more effectively than The Trade Desk (TTD). As the largest independent Demand-Side Platform (DSP), TTD has masterfully leveraged the demand for transparency to consolidate its own market power. Its flagship sell-side initiative, OpenPath, is marketed as a "direct connection" to publisher inventory, promising a more efficient and transparent route to premium content. However, this initiative is a strategic masterstroke in market control. By creating its own preferred supply routes, TTD is effectively bifurcating the market into its proprietary ecosystem and the rest of the open internet.

This maneuver is more than just product development; it is the weaponization of language and market power. TTD has begun to strategically re-label traditional Supply-Side Platforms (SSPs) as mere "resellers," a semantic shift designed to devalue its competitors. Its powerful AI engine, Kokai, is engineered to penalize these "resold" paths and steer billions in ad spend toward TTD-controlled products like OpenPath. While framed as a victory for transparency, this strategy serves to tighten TTD's grip on the flow of ad dollars and expand its own revenue capture. The very definition of "transparency" has become the new competitive battleground. TTD's version of transparency is one that is defined, curated, and controlled entirely within its own ecosystem. It is a marketing claim, not a verifiable state.

This dynamic reveals a critical market vulnerability. The incumbent leader of buy-side programmatic technology is not ignoring the demand for transparency but is actively co-opting the term to reinforce its moat and build a more formidable walled garden of its own. This creates a powerful strategic opening for a model that offers a fundamentally different kind of transparency. The market does not need another commercially motivated closed solution. It needs a transparency that is radical, verifiable, and community-governed—a transparency rooted in open-source code and cryptographic proof, standing in stark contrast to the proprietary models seen in the market today.

Lessons from the Sell Side Header Bidding Revolution

The viability of an open-source, community-driven standard in ad-tech is not a theoretical proposition; it is a proven historical precedent. The success of header bidding as a whole provides a great case study for challenging centralized control within the advertising ecosystem. Prebid emerged as a direct response to the inefficiencies of the "waterfall" ad serving model, a rigid, sequential system that privileged the primary ad server (historically Google) and limited publisher revenue. It was a highly effective sell-side driven approach to dealing with the monopolization of certain online advertising technology markets caused by the bundling of publisher ad server and ad exchange together.

Prebid fundamentally democratized the sell-side by creating a unified, open-source framework for header bidding. This allowed publishers to conduct a fair and simultaneous auction among multiple demand partners directly in the user's browser, dramatically increasing competition and revenue. Prebid.js rapidly became the de facto industry standard for several key reasons. Its open-source nature fostered unprecedented industry-wide collaboration and innovation, leading to a rich ecosystem of over 300 demand source adapters and 50 analytics adapters. Its lightweight, modular architecture gave publishers the flexibility to build efficient, customized implementations tailored to their specific needs. Most critically, the establishment of Prebid.org as a neutral, community-governed body ensured that the project would serve the interests of the entire ecosystem, rather than being captured by a single corporate entity.

The Prebid revolution showcases the spirit, ingenuity and resilience within the ad-tech industry. The ecosystem exhibits a powerful "immune response" to excessive centralization. When a single player or a closed, proprietary model becomes too dominant or extractive—as the waterfall model did—the broader community of publishers, agencies, and independent technology providers will inevitably rally around an open, neutral standard that restores balance and fairness.

Today, a new wave of centralization is occurring, this time on the demand side, driven by the strategic consolidation of DSPs like The Trade Desk. The same conditions that gave rise to Prebid are re-emerging. The market is once again facing a powerful, centralizing force that threatens to dictate terms and extract disproportionate value from the supply chain. The success of Prebid demonstrates a profound and persistent market appetite for non-proprietary, transparent standards that solve fundamental inefficiencies. This history provides a clear validation for the thesis that the ecosystem is ready for the next iteration of this immune response—a neutral, open standard for the buy-side.

The Market Mandate for Open Standards

Synthesizing these market dynamics—the crisis of transparency created by dominant platforms and the proven success of the open-source Prebid model—leads to an undeniable conclusion. Just as Prebid created an open standard to bring fairness and efficiency to the sell-side, the market now requires a neutral, open-source standard for the entire advertising ecosystem. The consolidation of power by major platforms creates an urgent need for a counterweight: a transparent, community-governed network that serves the interests of the entire ecosystem without a conflicting business model designed to extract value from the supply path.

This project is a strategic intervention in the future architecture of the open internet, how we fund and monetize content and experience media. It represents a philosophical alternative to the prevailing model of centralized control. By offering a truly transparent and auditable standard, it empowers all participants with sophisticated functionality without the prerequisite of proprietary lock-in. Unwalled is designed to embrace and interoperate with existing standards like OpenRTB and sell-side projects like Prebid, creating anchors to the legacy ecosystem and treating incumbent DSPs and SSPs as valued sources of liquidity and innovation.

The market mandate is for a standard that embodies a new set of principles. It must be auditable at the code level, governed by its community of users, and designed to maximize efficiency for all participants, not value capture for any single platform. This is the clear and present opportunity to build not just another tool, but the standard for a truly open network.

A New Foundation for Global Advertising

While the principles of open-source software provide a powerful counter-narrative to the closed ecosystems of traditional ad-tech, they represent only half of the opportunity. A truly disruptive solution cannot merely replicate the past; it must build the foundation for the future. The emergence of decentralized technologies provides the architectural and philosophical toolkit to solve problems that are intractable within the existing paradigm. This section explores how leveraging these principles can elevate the project from a transparent tool to a transformative network, addressing the fundamental issues of identity, data ownership, privacy, regulations and value exchange that lie at the heart of the industry's dysfunction across all digital touchpoints—from websites and mobile apps to connected television streams.

Principles of a Decentralized Ad Ecosystem

The transition to a decentralized advertising model represents a fundamental reordering of the relationship between brands, platforms, and users. The current model, dominated by centralized platforms, is defined by the harvesting of user data to fuel targeting algorithms. In this model, the user is the product. In contrast, a decentralized model is about building movements, activating communities, and fostering direct relationships between brands and consumers.

This shift is being propelled by a powerful undercurrent: a growing consumer demand for data privacy and ownership. Surveys in 2024 indicated that over 70% of internet users are concerned about their online privacy, driving a migration toward platforms that offer greater security and user control. This is not merely philosophical; it is creating a new competitive landscape. Decentralized ad networks are emerging to serve this new ecosystem, differentiating themselves with features like hyper-targeting based on on-chain wallet activity and the use of token rewards to incentivize user engagement. The most significant shift, therefore, is not technological but socio-economic.

A successful decentralized advertising network cannot be a mere continuation of the old model with a transparent veneer. It must be an engine for community creation and economic empowerment. Its success can be measured not only by traditional metrics like viewability, video completion rates, in store sales, and conventional Return on Ad Spend (ROAS) but by the economic and social impact of the ecosystem it fosters. This project is not just building an ad-tech tool; it is architecting a system where the audience is no longer the product but a key stakeholder.

High-Frequency and High-Volume by Design

The fundamental problem with the current state of Real-Time Bidding (RTB) is its inefficiency. Similar to interbank foreign exchange markets, there is no transparent, unified order book for the buy and sell side. This leads to massive bid duplication and inefficient matching, with transactions taking tens or even hundreds of milliseconds to resolve.

Unwalled is fundamentally architected to solve this. In this decentralized model, the network nodes can create consensus on a global, transparent order book that can match buy and sell orders in microseconds. This high-volume and high-frequency environment requires an infrastructure capable of handling millions of transactions per second with near-instant finality and extremely low costs.

Rather than building on a single, general-purpose blockchain, the Unwalled architecture is inspired by high-performance solutions implementing its own specialized transaction layer. This layer processes the immense volume of bidding activity on a dedicated application chain, with only the net settlement results being committed to a highly scalable and secure base layer. This allows the network to work with and be anchored to high-scale solutions like Keeta ($KTA), using them as a settlement and identity layer for onboarding ad spend budgets, distributing user rewards, and maintaining user identity, without being constrained by their native latency and cost for every single bid. This hybrid approach provides the speed of a centralized system with the security and verifiability of a decentralized ledger. This is demonstrated through many proof-of-stake style blockchains that have layered finality or the dichotomy between Hyperliquid Exchange ($HYPE) for HFT and their separate EVM.

Value Exchange

A key principle of Unwalled is to focus on perfecting the advertising transaction layer while integrating with best-in-class solutions for identity and finance. This creates a complete, end-to-end ecosystem that is transparent, efficient, and re-aligns incentives for all participants.

The most central theme of this is positioning real human users as a key stakeholder and a hedge against AI bots. If a bot wants access to the same resources as humans instead of getting a financial incentive and creating non performant advertising, they will be charged a toll using x402 protocol style transactions. The primary incentive for a user to participate is to reclaim ownership of their data and be fairly compensated for their attention. By creating a pseudo-anonymous Decentralized Identity (DID), the user gains granular control over their ad preferences and what data they share. This DID, managed through a user-controlled digital wallet, becomes their passport to a more equitable internet, providing them with full transparency into how their data is used and, most importantly, enabling them to receive a direct share of advertising revenue. This verification can be anchored by on-chain identity solutions like SOLO's PASS, which consolidates real-world financial credentials or Footprint secured personal data providing a robust layered verifiable on-chain identity. This prevents botnets from creating fraudulent identities to illegitimately claim user rewards, ensuring that value flows to real human users and that advertisers are paying for genuine attention, not machine-generated impressions.

Flow of Value

Brand Marketer and Agency Funding: A brand or its agency deposits funds (fiat converted to $KUSD stablecoin) into a treasury used to back credit for their campaigns governed by payment terms as a function of their on-chain entity’s credit score. This provides a transparent and auditable pool of secured credit for executing advertising transactions. Through the use of identity certificates, buys can be executed at scale without being constrained by individual transaction settlement time details and can top up or withdraw funds instantaneously.

Publisher and User Payments: As ads are served and verified on-chain (using the Keeta layer for settlement), the campaign automatically executes revenue distribution based on the payment terms offered to the buyer. Publishers and media companies receive their share of the ad spend directly to their wallets, eliminating the long and opaque payment cycles of the current system. Simultaneously, a predetermined portion of the revenue is rebated directly to the user who viewed the ad, closing the value loop.

Outcome-Based Incentives: Campaigns can be programmed with complex attribution reporting and rewards logic. This allows for dynamic, outcome-based rewards. For example, a publisher could earn more revenue for an ad that led to a latent but verifiable conversion, or a user could receive a bonus for engaging with the campaign in a specific way. This moves the entire system beyond simple impression-based payments to a full cycle holistic performance-driven model.

This modular approach, combining a high-speed advertising layer with specialized identity, settlement and financial protocols, allows Unwalled to remain focused on its core function while providing robust, enterprise-grade financial services to the entire ecosystem for the next revolution in advertising.

The Future is Unwalled

We have a choice between two futures: one where our digital lives are confined within ever-higher walls of proprietary control, or one where value, creativity, and identity flow freely on an open and verifiable foundation. Unwalled is the architecture for an internet where truth is cryptographic, attention is rewarded, and innovation is permissionless. We are not just optimizing a supply chain; we are architecting a new economy where every user is a stakeholder, not a product.

Together, we'll replace the walled gardens with an open field of possibility. Excited to set a new standard for a truly free and fair digital world.
