Dbrain – The blockchain platform to collectively build AI Apps

80% of AI is data. Datasets for machine learning are still labeled by hand and require a lot of effort. They provide a simple tool for crowd workers and data scientists to turn data into real-world AI solutions.


Artificial Intelligence (AI) happens to be the next big thing. AI is all about data. Datasets used for machine learning are still labeled by hand, which requires a lot of effort. This creates a lot of friction: labeling quality is not guaranteed, and the initial source data is not secured. Dbrain allows people to work together in secure, seamless, integrated processes for buying, designing, and building AI apps, from start to finish.

Dbrain is an open blockchain platform that links crowd workers and data scientists enabling them to transform raw data into real-world AI solutions. Crowdworkers do simple tasks of data labeling and validation and are paid instantly in cryptocurrency for their work.

Blockchain technology helps them meet many of AI’s current challenges. Using the blockchain, they can confidently manage high-quality data labeling, security concerns, intellectual property rights, and international micropayments.

 They use blockchain protocols and an in-house cryptocurrency to power the AI production cycle. The SPOCK protocol validates data label quality, ensuring the most accurate datasets possible. The PICARD protocol ensures the security of confidential data and automatically manages relations and fair revenue distribution between stakeholders. Dbraincoin (DBR) is an ERC-20 cryptocurrency to exchange for work, datasets, and AI app usage.

Anyone with a connected device can join Dbrain and get a role in building Industry 4.0. Their platform connects exploding demand for hand-labeled AI data with the abundant supply of global crowd workers.


Blockchain technology helps them meet many of AI’s current challenges. Using existing commercial computation infrastructure allows them to build an affordable, scalable toolkit for developing, integrating, and deploying AI apps.

Dbrain guarantees a quality of datasets without any work duplication. To align the incentives for crowd workers, validators, AI developers, and data owners, Dbrain implements the Subjective Proof of Crowdwork Protocol (SPOCK), which validates data quality automatically and guarantees real-time, fair, transparent billing to workers and data owners.

The supply of online crowd work is abundant globally. The World Bank estimates that in 2013 the minimum total supply of crowd work was $239B, while the market demand in 2016 was $4.8B, or 50 times less than the work supply. Only demand limits the market growth.


Global job automation trends and widespread internet penetration in emerging markets accelerate the transformation of the classic employment model into an online work model, which is divided into small, well-defined tasks, most of which do not require any special expertise.


Dbrain is an open blockchain platform for turning raw data into real-world AI solutions. They make AI accessible to businesses and allow anyone to earn money for their effort.

Dbrain levels the playing field for all participants on the AI market. The Dbrain platform works on the Ethereum network and relies on its smart contracts. They are building a scalable permissioned blockchain anchored to the Ethereum network via state channels.

To align the incentives of crowd workers, validators, AI developers and dataset owners, Dbrain implements the Subjective Proof of Crowdwork Protocol (SPOCK), which automatically verifies data quality and guarantees real-time, fair and transparent billing to workers and task requesters.

The Protocol for indirect controlled access to repository data (PICARD) protects datasets and AI applications hosted on the Dbrain platform and allows data scientists to train AI models using the datasets without downloading them, and to sell AI solutions to business clients later.

Dbraincoin (DBR) is implemented as a standard ERC20 token. The total number of Dbraincoins in existence is fixed.


There are a few large existing crowd work platforms that are mostly used for AI-related tasks (e.g., Amazon Mechanical Turk, Yandex.Toloka). However, they fail to meet most of AI developers’ needs.



The Dbrain platform provides a scalable and accessible infrastructure to supercharge businesses with high-quality AI, integrated via a convenient API. They offer a wide range of turnkey and custom AI solutions, integration, and customization for their clients’ particular needs. Static image recognition, video surveillance and action detection, medical data processing, and content analysis of text streams, which currently lack working solutions would benefit from business-ready AI solutions.

Their AI platform will save clients much more than the commission they charge because they do not have to set up any infrastructure for data labeling, AI development, training, and deployment.
