Introduction to ZK Proofs

What are ZK Proofs?

ZK-proofs are a cryptographic protocol that allows one party to prove the truth of a statement to another party without sharing any of the statement’s contents. It is commonly integrated into digital identity solutions to ensure one’s identity can be proven without the verifier or anyone else needing to see original documentation.

ZK proofs are used to prove to one party (the verifier) that another party (the prover) possesses some knowledge but without revealing the knowledge itself. The only information conveyed and proven to the verifier is that the prover does possess this knowledge.

Why are ZK Proofs important in Web3 advertising?

ZK Proofs play a crucial role in blockchain advertising by addressing the dichotomy between transparency and privacy. They allow for transactions to be validated without revealing sensitive data. This is especially important in the advertising industry where user privacy is a top concern. By using ZK Proofs, advertisers can target users with relevant ads without compromising their personal information. This helps build trust between advertisers and users, leading to a more secure and privacy-preserving advertising ecosystem.

Challenges in using ZK Proofs in Decentralized Blockchain Advertising

Scalability issues

Implementing ZK Proofs on blockchain networks, particularly for advertising, requires a balance between computational efficiency and privacy. ZK Proofs can be computationally intensive, which might slow down transaction processing on the blockchain. The mathematical and cryptographic complexity of ZK Proofs can be a barrier to widespread adoption, especially for advertisers and users who are not familiar with the underlying technology. Although STARKs (Scalable Transparent ARguments of Knowledge) are a newer generation of zero-knowledge proof systems that are used to create proofs that are both succinct and can be verified quickly.

Transaction Cost

Integrating zero-knowledge proofs into blockchain transactions can affect the cost of these transactions in several ways. One significant factor is computational complexity; the generation of a zk-proof is computationally intensive, requiring more resources from the party creating the proof. This increased demand for computational power can lead to higher costs for those generating zk-proofs. Additionally, zk-proofs typically increase the size of transactions. In blockchain networks where transaction costs are calculated based on data size, like Ethereum, this enlargement of transaction data can result in more expensive transactions.

ZK Proofs for Privacy-Preserving Ad Targeting

How ZK Proofs can protect user privacy in ad targeting

ZK Proofs offer a solution to the challenge of balancing privacy and transparency in blockchain advertising. They allow for transaction validation without exposing sensitive data, ensuring user privacy while maintaining the integrity of the ad targeting process. By leveraging ZK Proofs, advertisers can target specific audiences without revealing any personally identifiable information. This helps protect user privacy and prevents the misuse of personal data. Additionally, ZK Proofs enable ad platforms to verify the accuracy of ad impressions without compromising user privacy. This builds trust between advertisers and publishers, fostering a more transparent and secure advertising ecosystem.

Benefits of using ZK Proofs in ad targeting

Using ZK Proofs in ad targeting offers several benefits:

• Privacy protection: ZK Proofs allow advertisers to target specific audiences without revealing sensitive user data.

• Improved trust: By using ZK Proofs, advertisers can verify ad impressions without compromising user privacy, building trust between advertisers and publishers.

ZK Proofs provide a trustless scalability mechanism, ensuring that third-party servers don't need to be trusted.

• Efficiency: ZK Proofs enable data batching in transactions, reducing computational requirements and improving efficiency in ad targeting.

• Fraud prevention: ZK Proofs can help detect and prevent fraudulent ad clicks, enhancing the integrity of ad campaigns.

Ensuring Advertiser Trust with ZK Proofs

Verifying ad impressions without revealing sensitive data

Verifying ad impressions is a crucial step in ensuring the accuracy of advertising campaigns. However, it is equally important to protect the privacy of sensitive data.

The goal is simple: the user needs to assure the advertiser that they've seen the ad without revealing any personal details, like where or when they saw it.

A Zero-Knowledge Proof allows a user to prove that they have seen a specific ad without revealing any personal information. The user, acting as the 'prover', generates a cryptographic proof. This proof is structured to encapsulate only the fact that the ad was viewed, without including any details about the user's identity, location, or the exact time of the ad viewing.

The specific thing sent back to the advertiser or the verifying party, who acts as the 'verifier', is this cryptographic proof. It usually appears as a series of numbers or a digital token, created through the ZKP protocol. This proof is a complex mathematical statement that essentially says, "I have seen the ad, and here is the cryptographic evidence to prove it," without divulging any additional information.

Upon receiving this proof, the verifier uses a corresponding algorithm to check its validity. Successful verification of the proof confirms that the user has seen the ad, but the verifier learns nothing more about the user or the viewing context. This ability of ZKPs to prove the possession of knowledge without revealing the knowledge itself or any other details makes them a powerful tool for preserving privacy in digital interactions.

Let's break it down further:

1. Selective Information Encapsulation: In a ZKP, the information that the proof contains is highly controlled and limited. The proof is constructed in such a way that it only confirms one specific fact: the ad was viewed. It does not contain, nor does it infer, any other information about the viewer or the viewing circumstances.

2. Cryptographic Techniques: This selective encapsulation is achieved using complex cryptographic techniques, such as SNARKs and STARKs. These techniques allow the creation of a proof that can be verified for its truthfulness without needing to expose the underlying data that led to the creation of the proof.

3. How It Works: For example, in an ad viewing scenario, the ZKP might involve the user performing a series of cryptographic operations that are unique to the event of seeing the ad. These operations produce a result (the proof) that can be checked by the advertiser. However, crucially, this result does not contain any extractable data about when, where, or who viewed the ad. The advertiser can verify this proof to confirm that the ad was indeed viewed, but they cannot glean any additional information from it.

4. Privacy Preservation: This method ensures the privacy of the user is maintained. While the advertiser receives confirmation that their ad was viewed, they do not receive any personal information about the viewer. The user's privacy is preserved because the proof does not encapsulate or reveal any personal data.

Building trust between advertisers and publishers

Building trust between advertisers and publishers is crucial in decentralized blockchain advertising. With the use of ZK Proofs, advertisers can verify ad impressions without revealing sensitive data, ensuring transparency and accountability. This helps establish a trustworthy relationship between advertisers and publishers, as advertisers can have confidence that their ads are being displayed to the intended audience without any manipulation or fraud. By leveraging the power of ZK Proofs, blockchain advertising platforms can create a secure and trustworthy ecosystem for all stakeholders involved.

ZK Proofs for Ad Fraud Detection

Preventing ad fraud with ZK Proofs

Ad fraud is a major concern in the advertising industry, costing businesses billions of dollars each year. With ZK Proofs, advertisers can verify the authenticity of ad actions without revealing sensitive user data. By using a ZK Proof at the time of a user interacting with an ad, we ensure that only valid actions are counted, preventing fraudulent activity. This helps to build trust between advertisers and publishers, as advertisers can be confident that their ads are reaching real users and publishers can demonstrate the effectiveness of their ad placements.

An example might be along the lines of:

# Code to track ad impressions and clicks
def track_ad_interaction(user_id, ad_id, interaction_type):
    # Record the interaction details
    interaction_data = {
        "user_id": user_id,
        "ad_id": ad_id,
        "interaction_type": interaction_type, # e.g., "click" or "impression"
        "timestamp": current_timestamp()
    }
    return interaction_data

then:

# Function to generate a ZK Proof for an ad interaction
def generate_proof_for_interaction(interaction_data):
    # Create a statement about the interaction without revealing user details
    statement = create_statement(interaction_data)

    # Generate a Zero-Knowledge Proof for the statement
    proof = zk_system.generate_proof(statement)
    return proof

Implementing ZK Proofs in Blockchain Advertising Platforms

Technical considerations for integrating ZK Proofs

When integrating ZK Proofs into a blockchain advertising platform, there are several important technical considerations to keep in mind:

1. Scalability: ZK-based solutions offer scalability by eliminating the need for trusted third-party servers. Verifiers only accept valid proofs, preventing collusion.

2. Data availability: Different ZK-based architectures, such as zkRollup, validium, and volition, address the data availability issue in various ways.

3. Efficiency: ZK Proofs can increase efficiency by allowing for data batching in transactions, reducing computational requirements and data storage.

4. Challenges: While integrating ZK Proofs has become easier with projects like Nova, Lasso, and Jolt, challenges such as reliable scalability and safe interoperability still need to be addressed.

Introduction

The rapid evolution of the internet has brought us to the beginning of a new era: Web3. Unlike the centralized and siloed systems of Web2, Web3 champions decentralization, peer-to-peer interactions, and transparency. But, as we step into this decentralized future, there's a pivotal need for an open discovery layer to nurture the growth we've experienced so far.

The Internet’s current discovery layer’s power is concentrated in the hands of a few dominant platforms. This not only encompasses advertising, but social media as well.

Imagine a future where user privacy is built into online ads, the value generated by this data is more equally distributed, and advertisers and publishers can trust they are getting what they are paying for. Utilizing blockchain, and more specifically, Zero Knowledge technology, a decentralized advertising layer can tackle these problems and create a more equitable online experience for all. For this post we will concentrate on new advertising technology when we say “discovery layer”, though, to keep things focused.

What is an Open Discovery Layer?

An open discovery layer operates as an decentralized intermediary between advertisers, publishers, and end-users. This layer ensures equitable, transparent, and efficient distribution of content or assets, ensuring everyone gets fair value without centralized gatekeepers.

Because of the open nature of decentralized protocols, open advertising protocols can provide a platform for anyone to build tools that will bring value to components in the ecosystem.

Furthermore, technical improvements to blockchain platforms like Ethereum, including ERC-6551 and zero knowledge proofs, are creating the perfect environment to build an open layer for product distribution on the internet.

At it's core, creating an open layer for discovery will lead to more experimentation in the stagnant ad industry, leading to a better and more equitable experience for all in the future attention economy.

Advantages for Advertisers

Transparency and Trust

In the realm of advertising, the clarity of transactions and placements is paramount. Decentralized ad networks built on open advertising protocols will allow advertisers to have a clear view of where their ads are being placed. This ensures that ads reach the intended audience and are not misplaced or misrepresented, fostering a greater sense of trust between advertisers and the platforms they use.

The ERC-6551 standard can be used to create NFT ads that tie performance immutably to an ad.

In the example above, the ERC-6551 standard can be used to create a transparent folder structure to easily understand the chain of ownership. Updating metadata at the ad level will provide the necessary transparency to understand performance metrics at the ad and ecosystem level.

Cost Efficiency

One of the significant advantages of an open discovery layer is the potential reduction of intermediaries. Traditional advertising models often involve several middlemen, each taking a cut of the profits. By leveraging an open advertising protocol, advertisers can bypass many of these intermediaries, leading to potential cost savings. This means that more of an advertiser's budget can be directed towards the actual promotion, rather than administrative or intermediary costs.

Creating new ad standards that, for example, support advertisers broadcasting their intent to pay for new users, essentially making each advertiser their own ad exchange will flip the advertiser / publisher relationship on it's head. Advertisers will be able to control which publishers can access their demand and publishers will have to keep the quality of users they send to advertisers high.

An example of what can be built with the above is a service for ad publishers that optimizes advertising content based on ZK proofs of users' in-app actions.

Fraud Reduction

The transparency inherent in blockchain technology can play a pivotal role in reducing ad fraud. Every transaction on the blockchain is recorded and can be verified by all parties involved. This transparency ensures that all parties can audit transactions, making fraudulent activities more challenging to execute and easier to detect.

Open protocols may introduce the potential for bad actors to game the system, however, but the open nature also allows the creation of fraud detection tools and registries to combat this issue.

Advantages for Publishers

Fair Compensation

Publishers often grapple with opaque pricing models and arbitrary rates. With open networks, they are assured of fair compensation for their ad spaces. Transparent metrics drive this, ensuring that pricing is based on clear and verifiable data.

Direct Advertiser Relationships

The elimination of middlemen in decentralized networks allows publishers to form direct relationships with advertisers via use of a discovery layer protocol. This direct communication can lead to more tailored and effective advertising campaigns, benefiting both parties. Publishers can have the option of controlling their user's advertising experience at an ecosystem level instead of at the network level.

Diverse Revenue Streams

An open advertising protocol, especially those utilizing smart contracts, offer publishers the flexibility to incorporate a variety of revenue models. From traditional pay-per-click models to more intricate conditional payment structures, publishers have a broader range of options to monetize their content.

As the use of zero knowledge proofs increases, the use case of showing a user the right offer at the right time will unlock a world of payment options that are underwritten by adverting dollars. A diverse number of algorithms that will allow a publisher to offer multiple ways to maximize revenue at the user level.

Advantages for End Users

Privacy

A massive subject that cannot be fully explored here, but at it's core a decentralized discovery/distribution layer must prioritize user data sovereignty to ensure maximum privacy. Unlike centralized systems, where user data can be a vulnerable point of exploitation, decentralized networks can offer better safeguards, ensuring that users are not unwittingly exploited for ad targeting. Again, ZK proofs will play an integral role here. If natively built into a discovery protocol, we are on our way to user control of the advertising landscape. This will open up entirely new ways of thinking by advertisers to get their products noticed.

Monetization Opportunities

The advent of Web3 technologies presents users with unique opportunities to monetize their attention or data sharing. This means that users can effectively become stakeholders in the advertising ecosystem, benefiting directly from its growth and success.

For example, a ERC-6551 smart wallets that distribute discovery protocol sub-tokens could distribute referral rewards earned from advertising fees.

Relevant Content

As decentralized advertising systems become more transparent and efficient, end users stand to benefit from more relevant ad content. This efficiency can lead to a reduction in the barrage of irrelevant ads, enhancing the user experience.

A discovery protocol can give users the tools to block categories of ads (casino, for example) or ad types (video, popup, etc), at the browser level with extensions or even at the OS level in the case of EthOS.

Advantages for Those Outside Traditional Networks

A decentralized discovery layer on the internet offers a beacon of hope for those in regions or situations where traditional centralized ad networks might be inaccessible or show bias. The playing field is leveled, allowing anyone, regardless of their location or status, to join and participate.

There is more opportunity for small players because they can leverage the entire network to work to their benefit. Instead of adapting to the rules of centralized behemoths, the composability of the open advertising stack will open new markets for product distribution in areas yet to be seen.

Futureproofing the Web: Strengthening the Case for an Open Discovery Layer

The digital landscape is rapidly evolving towards decentralization. By establishing systems that support this shift now, we can ensure a smoother transition in the future. This proactive approach can help mitigate potential conflicts and systemic shocks that might arise from a sudden shift.

By championing an open discovery layer, the digital space can move towards setting global standards. These standards can cover various aspects, from transparency to payment and content distribution, making the digital realm more predictable and trustworthy for all stakeholders.

Let’s create resilience. Our current system is vulnerable to failures, hacks, or control by a single entity. Decentralizing the discovery layer of the internet will distribute risk and control, ensuring greater longevity and stability for everyone.

The evolution towards Web3 is more than just a technological shift; it represents a fundamental change in how we perceive and interact with the digital realm. By advocating for an open discovery layer, particularly in sectors like advertising, we are addressing present-day challenges. More importantly, we are laying the groundwork for a digital future that promises to be more inclusive, transparent, efficient, and open.

At the Open Ads Protocol, we like to think deeply about the more recent history of marketing: digital advertising. In the past 20 years, we have seen a revolution in the advertising industry like no other. In order to understand where the industry is headed, it’s important to take a step back and appreciate how far we’ve come and learn from prior pitfalls to help illuminate the path ahead.

Our team believes that the future of advertising is a transparent model that focuses on the customers first. Let’s rewind the tape and stroll through the evolution of digital advertising.

Pre-Google era (1994 - 1999)

The first chapter starts in 1994 when there were an estimated 30 million people online worldwide. HotWired, the web version of the beloved Wired magazine, displayed this ad for AT&T, with a message “Have you ever clicked your mouse right here? You will”. 

A new industry was born.

With the success of AT&T's banner ad, advertisers sought ways to better target their ads. WebConnect, the first ad network, emerged in 1995 to help advertisers identify websites their ideal consumers frequented, thus placing ads where they were most likely to be seen by the relevant audience​.

The increase in online display ads led to the need for measuring ad performance. In 1996, DoubleClick, one of the world's first ad servers was introduced, enabling advertisers to track their ad's performance and better target internet users. DoubleClick also brought about ROI tools for ad campaigns, allowing businesses to evaluate the effectiveness of their advertising spend, a major step in the growth of the industry.

Then, some guy invented pop-up ads in 1997, making online ads go from mildly intrusive to universally hated.

I could have picked a much more obnoxious example. Due to their intrusive nature, pop-up ad blockers were quickly developed, reducing their effectiveness very quickly.

As the web expanded rapidly, search engines emerged to help users navigate the vast amount of information online. 1998 saw the introduction of paid search and Pay-Per-Click (PPC) advertising by GoTo.com. Google was founded this year and in a couple of years their market share and innovative ad units would change the game.

We should note, though, pioneers like G.M. O'Connell and his venture Modem Media were among the first to navigate the uncharted waters of digital advertising as early as 1987. Their foray through the late 90s, though embryonic, set the framework for the digital advertising landscape we are familiar with today.

Google / Facebook Era (2000 - 2010)

As the calendar flipped to 2000, Google unveiled AdWords, planting a milestone in the digital advertising timeline. Their version of the Pay-Per-Click model and the ability to bid on individual keywords made advertising both affordable and measurable. For instance, small businesses could now set a budget cap and only pay when someone clicked on their ad.

Now, down we go into the rabbit hole of context based ads, a targeted advertising approach that displays ads to users based on the content they are currently engaging with online. They aim to deliver ads that are contextually relevant to the webpage or content, increasing the likelihood of capturing the user's interest and engagement.

By tracking a user's online behavior, such as the websites they visit, the content they interact with, and their search queries, ad networks were now able build a profile of the user's interests and preferences.

The plot thickened post-2007 when Facebook joined the advertising bandwagon. With a treasure trove of social data, Facebook ads offered a level of personalization that was unmatched. The ability to target ads based on user demographics and interests was a game-changer. For instance, a local pizzeria could target ads to pizza lovers within a specific zip code, or political parties could tailor a message about their candidate depending on a user's political preference.

Through the rest of the decade more and more people came online. These methods of giving people an ad they were most likely to engage with based upon troves of data was continually being refined. The end result being the incumbent, Google, and the up and comer, Facebook, poised to take advantage of the next billion people coming online.

Mobile Ads (2010 - Present):

The narrative takes a mobile turn post-2010 after the iPhone's launch a couple of years earlier.

The launch of app stores, particularly Apple's App Store in 2008, created a thriving ecosystem for mobile apps. This presented a new advertising channel as developers sought ways to monetize their apps. Advertisers started placing ads within mobile apps, including banners, interstitials, and rewarded video ads, creating a billion dollar industry by 2011.

The period from 2008 to 2014 was transformative for mobile advertising, as it evolved from early experiments to a mature and essential component of digital advertising. Advertisers increasingly recognized the potential of mobile devices to reach consumers in personalized and contextually relevant ways.

Simultaneously, the mobile gaming arena bloomed, creating a vibrant canvas for advertisers. Games like Angry Birds and Candy Crush became not just a source of entertainment but a platform for ads. The fusion of gaming and advertising delivered a unique blend, making ad experiences less intrusive and more enjoyable.

Ad-tech really started to hit its stride as mobile Free-to-Play (F2P) games adopted in-app purchases and rewarded advertising as its main form of monetization. Facebook, Applovin, IronSource and others refined their business models as free games battled for top positions in app store rankings fueled by in-app advertising.

However, the proliferation of mobile ads 2014 onward brought along a cloud of privacy concerns as the decade continued. The discomfort over personal data collection by big tech companies for targeted advertising fueled debates as issues like the Cambridge Analytica data collection scandal emerged. If you don't know, they used Facebook data to influence political outcomes in 2015-2018. This era threw spotlight on the delicate balance between personalized advertising and privacy, a dialogue that continues to shape the contours of digital advertising.

Platforms like Snapchat and Twitter also entered the arena around this time both using a similar data collection and monetization model to drive revenue on their products. On top of Google, Apple's, and Amazon's product offerings, the mobile consumer was opted-in to an internet with great free products at the cost of their privacy.

The ad tech landscape has been pretty stagnant since 2018 with few notable industry movements. The exception is Apple's decision to stop sharing iPhone users data externally, causing industry giants Facebook and Google to take a hit to their ad targeting capability. This is viewed by some as more akin to a game of chess than consumer-first thinking as Apple is ramping up its own ad targeting capabilities on the iPhone.

What's next?

Advertising has always been at the forefront of technology: adapting to use the latest and greatest tech that might help advertisers and publishers achieve their goals. 

Today, AI & blockchain tech are currently the elephants in the room. At OAP, we’re actively thinking about how innovations in these verticals will change the advertising landscape in the coming decade.

Our team believes that the most crucial lesson we’ve learned from the big tech era of advertising is that the model needs to be transparent, secure, & user oriented.

Enhanced personalization with robust privacy measures, the development of decentralized ad networks, and transparent and efficient real-time bidding systems are all real world use cases that we see as being the future.
