Frequently Asked Questions

Users can also join the AdHash voting community and earn AD tokens for their contribution.

Today as much as 80¢ of every $1 is spent on middleware and ad fraud mitigation, squeezing publisher margins and leaving little for quality content creation. The AdHash Protocol cuts the middlemen and minimises ad fraud, allowing publishers to gain more value from their audiences. 97% of all ad spend goes directly to publishers. Payments are issued daily.

On top of that, publishers can benefit from additional revenue streams by minting rewards for each verified click and participating in the AdHash Voting System.

By providing unique and tamper-resistant hash IDs for all participants and ad creatives in the ecosystem, the AdHash protocol stores all important interactions on the Ethereum blockchain. Detailed private information about campaigns is still stored securely on marketers’ servers, but the history of serving and modifying ads is stored forever in a distributed ledger that can be accessed by anyone. These innovations allow AdHash to introduce for the first time a mechanism for self-hosting ads, allowing advertisers to combat ad fraud by relying on their first-party data instead of third-party data provided by intermediaries.

On top of that, a voting mechanism guaranteed by the participants’ deposits ensures that independent researchers can track signs of even the slightest fraudulent behaviour, report it, and collect a reward if their findings are confirmed by the other members of the voting pool. Ad fraud is a lengthy subject, more details can be found in Chapter II of our White paper.

In today’s advertising industry personal information is compiled, profiled, traded, and exploited in any possible way. This has pushed many users towards ad blockers.

To stop this trend from spiralling down, we have taken measures to ensure that users’ personal information remains personal. Targeting is carefully calibrated to ensure a balance between data privacy and ad relevance. With AdHash, advertisers can target only by criteria which are directly measurable and 100% verifiable, not based on any extrapolations or third-party data. No personal information is stored on the blockchain.

For more information about targeting, visit our Help page.

AdHash equips users with a comprehensive set of tools to control their ads exposure. Thanks to our Unique Hash IDs, users can now quickly and effectively remove ads they do not wish to see. You can Flag and Block inappropriate ads from the Ad Quality Control icon at the top right corner of each AdHash ad.

For those who wish to remove ads altogether, AdHash is the first company to enable users to bid against advertisers on equal grounds. All you need is a wallet ID and some AD tokens to enjoy ad-free browsing while still supporting your favourite publishers.

The decentralised nature of the AdHash Protocol means that there is no single point of failure or central database to compromise. Private data is only stored on your own servers and could not be accessed even if other servers on the network get breached.

The blockchain ledger of transactions keeps a temper-proof record of the state of the network so that all participants can easily get back in sync should they experience temporary technical problems.

Yes, AdHash is fully compliant will the General Data Protection Regulation. No personal data is collected or stored by AdHash without the knowledge of its users. We created tools that make it easy to check how ads are being targeted at users and to remove all ads from anyone’s browsing experience.

For more information on some of the measure we take to protect information, please read our Privacy policy.

The current ad tech ecosystem is heavily intermediated. Publisher data can change hands up to 20 times before reaching the advertiser. On this convoluted journey, valuable information is often lost, distorted, or inflated by thousands of different ad tech companies. This leads to significant discrepancies and lack of trust.

AdHash’s goal is to eliminate those middlemen and allow advertisers and publishers to transact more directly. For the first time advertisers are guaranteed accurate data by relying entirely on first-party metrics. They store all measurement data locally on their own servers and can quickly and easily verify metrics with publishers.

Intrusive ads, slow page loading, and exploitation of personal data have pushed many towards ad blockers. We believe advertising should power meaningful conversations in a simple and non-intrusive way. To achieve this, we removed the disruptive ad formats, ad repetition, and third-party tracking scripts.

AdHash uses only static ads which do not distract from the content and are less heavy on the users’ hardware. Together with our algorithmic optimisations, this contributes to much quicker ad loading times and higher viewability.

The AdHash Voting System is designed to democratise and incentivise the decision-making process that governs our ecosystem. It serves to:

  • Secure the integrity of the ecosystem by allowing participants to proactively identify and block abusers within minutes.
  • Replace the ineffective creative approval process with a more efficient quality control process.
  • Facilitate self-regulation, enabling the network to be self-sustaining.
  • Provide a democratic framework for quick dispute resolution.
  • Give participants equal opportunity to contribute and earn AD tokens.

To learn more about the AdHash Voting System, please visit our Voting page.

The application of blockchain allows us to:

  • Implement Unique Hash IDs for each creative, advertiser, and publisher. They provide user control, prevent double-bidding inefficiencies, and ensure a more efficient media buying process.
  • Reduce the complexity and solve the trust issue by replacing the current intermediary structure with a direct and computationally verifiable transaction channel between advertisers and publishers.
  • Offer timely transactions by using a native cryptocurrency.
  • Build an incentivised consensus mechanism to secure the ecosystem.
  • Store the decisions governing the ecosystem in a publicly verifiable way.

AdHash carefully combines blockchain with off-chain usage to provide scalability, minimise transaction costs, and offer transparency while maintaining a level of privacy.

Recorded on the blockchain are:

  • Unique Hash IDs (for accountability and ad fraud prevention).
  • Bulk settlement transactions between advertisers and publishers (for transparency and verification).
  • Voting results (for a tamper-proof record of all decisions governing the ecosystem).
  • Block lists (to ensure that abusers can no longer participate).

Detailed information pertaining to the buying and selling of inventory between any two parties is stored off-chain to:

  • Ensure that any sensitive information such as media-buying patterns or monetisation strategies remains private.
  • Minimise the blockchain transaction costs.
  • Sidestep the current blockchain scalability limitations and facilitate the high-speed transactions of RTB advertising.
  • Automatically resolve disputes in the event of discrepancies between the data provided in on-chain transactions by advertisers and publishers.

RTB advertising transaction volumes are approaching tens of millions per second. With the emergence of header bidding in the past few years, that number has grown significantly. There is currently no blockchain that can handle this amount of transactions.

The AdHash off-chain transactions elegantly sidestep this problem. Detailed RTB data containing sensitive information such as media-buying patterns and monetisation strategies is stored securely on the publishers and advertisers’ own servers. Only bulk transactions, Unique Hash IDs, blacklists, and voting results are stored on the blockchain. The frequency of these communications is very small even for the arguably low current transaction speed of the Ethereum blockchain.

All transactions in the AdHash ecosystem are executed in a native cryptocurrency - the AD token. There are five main reasons that justify having a native token. It enables:

  • Micro transactions and quick settlement periods.
  • Our own economic model and incentive mechanism to reward contribution and further the development of the ecosystem.
  • A proof of stake mechanism and deposit system to secure the voting system.
  • Price stability. Unlike other cryptocurrencies, the values of which are mostly driven by speculation, the AD token is strongly tied to the real-world demand for buying and selling ads which makes it resilient to price volatility.
  • Insulation from any major cryptocurrency events not directly related to our product.

Publishers today pay their salaries, rent, taxes, and pretty much all other expenses in fiat currencies, just like most businesses do. As long as this remains the case, it will always be more convenient to receive fiat money instead of AD tokens. However, fiat transactions are slow and costly. In the advertising space, publishers usually wait a minimum of 55 days to receive their payments.

Publisher earnings paid in AD tokens, on the other hand, cost significantly less in transaction fees and are executed daily. The efficiency and speed far outweigh the hurdles of getting a cryptocurrency wallet.

As for advertisers, there are no more budget lock-ins. In most advertising platforms, funds, once deposited, are difficult or impossible to withdraw, should you decide to spend them elsewhere. With AdHash, you can quickly and easily retrieve your remaining AD tokens and convert them into any crypto or fiat currency.

You can buy AD tokens directly from AdHash. Our goal is to distribute the entire token supply to a wider community of advertisers and publishers as quickly as possible. For advertisers, buying AD tokens and using them to purchase advertising will be no different than running ads and paying for them in fiat currencies on any of the existing ad platforms.

You have two options:

  • As a publisher you will mint tokens for each verified click you provide on top of the price paid by the advertiser for that click.
  • As a voter you can reach the maximum rank of 100 points and begin to tokenise every additional ranking point you gain.

The rewards system is designed to consistently reflect each participant’s valuable contribution to the AdHash ecosystem.
