Basic Attention Token
Built with a similar goal in mind, Brave anonymously monitors user attention and rewards them with BAT tokens. Users can choose to share some of these rewards with verified publishers.
  • Brave shows very decent publisher growth and absolute numbers (see https://batgrowth.com/)
  • Handles monitoring and reporting of ad engagements
  • Ads are displayed as system notifications and displayed when the user is more likely to interact
  • Only works inside of Brave Browser
  • Market from scratch (no integration with traditional adtech)
  • Data is unverified
  • No identity data
The Brave browser knows where users spend their time, making it the perfect tool to calculate and reward publishers with BATs. This service creates a transparent and efficient Blockchain-based digital advertising market. Publishers receive more revenue because middlemen and fraud are reduced. Users opt-in to an inclusive and rewarding private ad experience. And advertisers get better data on their spending.
The Brave browser anonymously monitors user attention, then rewards publishers accordingly with BATs.
Ads are then anonymously matched with customer interests using local machine learning algorithms
Users viewing ads will be rewarded with BATs. BATs can be used for premium content or services on the BAT platform.
Publishers will, as part of this service, receive the lion’s share of the total ad revenue. We anticipate that users will also donate back some tokens to publishers, further increasing their revenue.
A Brave feature called Brave Rewards allows people who use Brave to contribute BAT to the sites they visit. When someone turns on Brave Rewards, their browser will tally the time and attention they spend on each site, and divide up that person’s monthly BAT contribution among the sites they visit. Brave Ads will allow people to opt in to earn BAT based on their attention. When someone turns Brave Ads on, their browser will begin learning their preferences in order to show occasional relevant ads as system notifications.


Transparent & privacy focused digital advertising
Blockchain-based ad exchange connecting advertisers and publishers directly. Monitors user behaviour to improve campaign performance.
A display ad network for reduced ad fraud and increased user privacy
With AdEx, you cut off intermediaries and save on unnecessary fees. We help advertisers and publishers maximize results and revenues - with the added value of real-time verifiable reporting.
We created AdEx because we realized that the ad tech industry failed to offer truly open source, transparent and fraud-proof ad networks. We decided to challenge the status quo. First, we connected advertisers and publishers directly, dropping the need for most intermediaries. Then we added real-time reporting, dramatically reducing the ability for any side to report wrong data to others for their own financial gain.
This means that if you are a publisher, for example, the middlemen between you and the advertiser has economic incentive to report lower traffic, impressions, number of conversions, etc. This way they would have to pay you less and keep a larger portion of the revenue. The only way to get that data is from the middleman, and you have practically no way of verifying the legitimacy of that data. In a decentralized and transparent system such as AdEx, this is not possible — since the data is uploaded from every individual user directly to IPFS (another decentralized system designed for storage). The finality of all that data is settled between the publisher and the advertiser on the blockchain (Ethereum), in a way that incentivises both parties to report all the data they have accurately. This achieves a transparent bidding process between publishers and advertisers directly, without any mediators, therefore removing the ability of anyone between the publisher/advertiser, or themselves, to hide data and cheat the other parties.
We are working on cryptography-based solutions to eliminate click fraud.
Core: The AdEx protocol builds on top of blockchain technology to facilitate the parts that need achieving consensus in a trustless, decentralized manner.
Market: The primary role of the market is to facilitate demand/supply discovery and trading. It keeps record of all campaigns that are currently valid, and allows publishers/advertisers to query that list in order to find what they need....
SDK: The SDK runs in the end user’s browser and builds a profile of the user and learns about them through the publishers and advertisers. Everyone who integrates the SDK has the ability to “tell” the SDK what they know. The incentive for this is built-in: better targeted ads mean higher revenues for publishers and higher ROI for advertisers....
Validators: One advertising campaign is mapped to a single payment channel, where the deposit is the entire campaign budget, and the validators are normally an advertiser-side and a publisher-side agents. Campaigns are regarded as valid only if ⅔ of the validators have signed the reported traffic generated on the publisher’s platform....
Platform: The platform is the GUI of the AdEx platform. Advertisers and Publishers submit and accept campaigns, choose validators and access stats for their campaigns on the platform....
Registry: an autonomous system designed to provide a list of publicly accessible validators that you can nominate for your campaign. The ultimate goal of the Registry is provide exposure for everyone who wants to be a public validator, and also to hold these validators accountable if they misbehave....

Word of Mouth Protocol

Start - WOM Protocol | The Future of Marketing is Ad-free
WOM Protocol | The Future of Marketing is Ad-free
Content creators share recommendations on their platforms, and authenticators validate the recommendations. When users engage with the recommended content, creators and authenticators earn WOM tokens — and so does the publisher. Advertisers post requests in a marketplace.
Content Creators share word-of-mouth recommendations on social media and other content platforms that have integrated the WOM Protocol.
Content Authenticators identify and validate the recommendations using the WOM rating system in the WOM Authenticator App.
Social media and other platform users engage with the WOM content and the creators and authenticators earn WOM Tokens
Content platforms earn WOM Tokens as consumers engage with content on their platforms.
Brands and advertisers use the WOM Campaign Manager and WOM Tokens to access, incentivize, and increase the reach of word-of-mouth recommendations.
WOM stands for “word of mouth”, i.e. recommendations between friends and followers. Recommendations can be made about anything: shoes, movies, festivals, video games, doctors, hairdressers, yoga instructors, etc. Recommendations made on WOM Protocol-supported platforms can be reviewed by authenticators. When the recommendation passes authentication, it is eligible to earn WOM Tokens.
Authenticators identify and validate valuable word-of-mouth content within the WOM Ecosystem. They use the WOM Authenticator app to validate recommendations according to: authenticity, creativity, and positivity on a 0-10 scale. They earn WOM Tokens for finding consensus with other authenticators and lose WOM Tokens if they deviate from the majority.

Swash, reimagining data ownership
Open-source browser extension that collects data as the user browses the web, anonymizes it, and sells it in a decentralized marketplace. The proceeds from these sales are shared with the users.
Swash uses Streamr, who calls them the world's first digital Data Union. See the post below for more on this:
We’ve open-sourced Swash to make Data Unions a reality
Swash is an open-source solution that makes it possible for you to monetise your surfing data. Simply install, browse, and earn - that’s it. Swash does all the rest for you and rewards you for the value of your data.
The current ecosystem doesn’t acknowledge that, without people, the digital economy wouldn’t exist. A select few reap the rewards that belong to the many by collecting, using, and selling our data in shady ways without hesitation or consequence.
Swash doesn't create any relationship between your identity and your data. Your only identifier is your Ethereum wallet address and a random unique identifier. The wallet address is used for authentication and payment purposes.


An open source, decentralized platform for real-time data. The Streamr Network — built on Ethereum using layer 2 scaling — is an incentivized data publishing/subscription system. They're reportedly a partner of Ocean's, as their functionalities slightly overlap but are mostly complementary, Streamr being possibly a delivery mechanism for Ocean data.
They're big on the concept of data unions (see their docs), and power Swash.
They make only a passing mention of advertising as a use case (here).
They offer development grants through their Data Fund.

Why use Streamr?

Data monetization‌. Unlock the value of user data without setting up your own custom infrastructure. A Data Union is a crowdsourced dataset, sold on the Streamr Marketplace, with providers incentivised via micropayments.
Plug and play data transport‌. Connect your data streams to a global, neutral data fabric. The Streamr Network is a robust, massively scalable peer-to-peer network for transporting machine data with the pub/sub pattern.
Deliver end-to-end encrypted data points to thousands of subscribers in under 400ms globally, without trusted middlemen. Nodes earn crypto by providing bandwidth. Data integration is as easy as five lines of code.
Blockchain security‌. Streamr uses smart contracts on the Ethereum blockchain to secure payments and data permissions. DATA, an ERC-20 standard token, is used for settlement and to incentivize network nodes to provide bandwidth for data transport.

Key Concepts

Streams are sequences of timestamped messages, delivered from publishers to subscribers by the Streamr Network.
Canvases are analytics and integration processes built using the visual programming environment included in Streamr Core.
Products are collections of streams which can be published onto the Marketplace and subscribed by other Streamr users.
DATA is the cryptocurrency which powers the Streamr ecosystem in various ways. It is an ERC-20 token on the Ethereum blockchain.

Data Unions

The Data Union framework is a data crowdsourcing and crowdselling solution. Working in tandem with the Streamr Network and Ethereum, the framework powers applications that enable people to earn by sharing valuable data.
Data Unions are like Data Products in that they also contain a bundle of real-time data streams. When a buyer subscribes to the product, the DATA revenue is automatically distributed among all of the data producers.
Data Unions may differ from each other based on their membership model, use cases, revenue structure or governance, but they also share some common components: a group of members contributing their data, an entity providing the application layer to manage the data and a discovery mechanism, or marketplace for the data.
The most valuable Data Unions will incentivize collection of datasets that may be otherwise difficult to source. Some examples include real-time health data, web user data, pollution monitoring, smart city data and more. Swash is the world's first Data Union - a browser extension that monetizes your browsing data. Streamr supports new Data Unions through the Data Fund.
