An entirely new approach to digital advertising for more efficient, transparent, and trustworthy media buying.

Return on ad spend

No more hidden fees

In the current advertising ecosystem, more than 70% of advertisers’ budgets are spent on middleware. Very little accounts for actual media buying. We call this the ad tech tax. AdHash helps advertisers increase their return on investment by reducing all intermediary fees to a single 3% commission which is verifiable through the AdHash Bidder.

No double-spending

Today’s market is fragmented and lacks standardisation across ad tech providers which often results in inefficiencies and unnecessary spending. Advertisers buying through multiple ad exchanges and DSPs simultaneously can easily end up bidding against themselves and artificially inflating their ad costs. AdHash eliminates double-spending by assigning a unique ad hash to every ad and advertiser, making sure that bids from the same advertiser do not compete against each other.

CPC bidding model

The Cost-Per-Click bidding model achieves a better balance between the needs of advertisers and publishers. You only pay when someone clicks on your ads. And a visitor can only click on an ad once your encrypted targeting criteria have been validated on the visitor’s device, providing an extra layer of protection against ad fraud.

No more budget lock-ins

In most advertising platforms, funds, once deposited, are difficult or impossible to withdraw, should the advertiser decide to spend them elsewhere. AdHash allows you to quickly and easily retrieve your remaining budget and instantly convert it to any digital or fiat currency.

No more ad fraud

The AdHash Protocol is carefully designed to eliminate 16 major ad fraud vectors. You can read more about them in our White paper.

Campaign performance, implementation, and optimisation

Enhanced control

The AdHash Server-Side Platform allows every advertiser to host his or her own node in our decentralised network. You can use it to set your bidding preferences, targeting criteria, CPC caps, blacklists, frequency and recency caps. You can even access the AdHash Voting System directly from the platform.

10 times faster ad serving

Slow ad serving impacts viewability because if the ad does not load, it cannot be seen. The AdHash algorithmic improvements reduce the ad request load on each server by up to two orders of magnitude. Removing heavy ad formats and third-party scripts further minimises ad loading time.

Accurate real-time data updated every 5 seconds

The AdHash Server-Side Platform measures data directly from your server in real-time, guaranteeing accuracy, consistency, and immediacy.

cryptographically verified targeting

No more targeting by approximated, probabilistic, and unreliable (yet expensive) third-party data. AdHash utilises only first-party data that are directly measurable and verifiable. This allows for more precise campaign planning and predictable outcomes.

Brand safety

Advertisers can curate their brand’s advertising environment through whitelists and blacklists. All publishers you transact with are disclosed and verifiable and traffic sources can be easily filtered. You can also flag and block inappropriate publishers from the entire network. For more information on blacklisting, blocking, and flagging, please visit our Help page.

Immediate campaign launching

In existing advertising platforms, all ads are subject to independent approval by each ad exchange. Across the exchanges, the approval process can take from a few hours to over a week, often resulting in delays in campaign launching. Using the AdHash Protocol you can get your campaign off the ground and running in minutes. All it takes is for the unique ad hashes of your ads to be recorded on the Ethereum blockchain.

Creative optimisation

Besides detecting fraudulent traffic, the AdHash heatmaps are an effective tool for analysing creative performance. You can determine which parts of an ad attract attention and optimise the design for better performance.


Viewability metrics are available for every ad position and are considered by the AdHash Bidder in the auction process.

Vastly reduced complexity, security vulnerability, and data discrepancies.

The AdHash Protocol and its unique ad hashes enable advertisers and publishers to transact directly and securely without the need for intermediaries. Campaign data is securely stored on your servers and never shown to any third-party vendors. The AdHash Server-Side Platform provides a standardised framework for data tracking and recording, minimising the discrepancies between transacting parties.

Balance between privacy and transparency

AdHash combines blockchain and off-chain transactions to offer transparency while maintaining a level of privacy. Detailed transaction data are stored off-chain and only on your servers. The application of off-chain transactions and public-key cryptography ensure that any sensitive information such as media buying patterns and bidding strategies remain private.

Two hosting options to suit all needs


You can install the AdHash Server-Side Platform directly on your servers for optimal performance. Host your creatives and monitor your campaigns locally, without engaging any third-parties. This gives you:

  • The full benefits of the AdHash Protocol by utilising direct ad serving.
  • Total data transparency.
  • 100% secure ownership of all information.
  • Reliance on first-party cookies only, making attribution metrics more accurate.
  • Configurable data storage.

All detailed advertising information is stored exclusively on your servers and not on AdHash's cloud storage.

AdHash Server-Side Platform


By signing up for AdHash Cloud, you can skip the technical setup and maintenance of hosting the Server-Side Platform yourself. We will host the platform for you on our secure servers while still giving you full control over your data and campaigns. You can always upgrade to the full self-hosted platform.
