A blockchain platform to collectively build AI Apps

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 crowdworkers and data scientists enabling them to transform raw data into real-world AI solutions. Crowdworkers do simple tasks of data labelling and validation, and are paid instantly in cryptocurrency for their work. Data scientists use the resulting datasets to train Neural Networks (NN) and build AI apps. Businesses use existing AI solutions or specify new ones to serve their particular needs. Dbrain automates AI production and data workflow by providing efficient tools to all parties, including a web application, a Telegram bot, and a mobile app. We 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. Our platform connects exploding demand for hand-labeled AI data with the abundant supply of global crowdworkers. In particular, we reach 2 billion unbanked people in low-wage countries, offering them cryptocurrency income in exchange for data labeling and validation. Integrating this global workforce into its platform, Dbrain provides a secure, unified infrastructure to supercharge businesses through accessible, high-quality AI products.

Security and trust
Dbrain protects data owners’ interests and prevents leaks at all stages of AI app development. No matter who uploads data on the platform, the Protocol for Indirect Controlled Access to Repository Data (PICARD) protects datasets and AI apps hosted on the platform. It also allows data scientists to train AI models using datasets without downloading them, and to sell AI solutions to business clients later on. The protocol guarantees security and trust in the Dbrain community with regards to data access control and reward distribution.

Dbrain is the channel for AI data labeling tasks. We see this situation as a blue ocean opportunity that allows us to build and control a substantial part of that market instead of fighting for a market share. Our platform will satisfy the exploding demand for human-labeled data and human-in-the-loop APIs. We will provide a better income for people who need it most and improve their quality of life, while managing to reduce data labeling costs for our customers.

Platform

Dbrain is an open blockchain platform for turning raw data into real-world AI solutions. We make AI accessible to businesses and allow anyone to earn money for their effort. The platform automates most of the data preparation and human-in-the-loop workflow. It provides crowdworkers with a user-friendly labeling and validation tool based on a unique web application and Telegram bot. Blockchain protocols and internal cryptocurrency ensure transparency and fair revenue distribution among all stakeholders.

SPOCK protocol

To align the incentives of crowdworkers, 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.

All work tasks performed on the Dbrain platform require multiple validations by other random labelers. Validators either do the same work for the simplest tasks such as image classification, or confirm the correctness of complex tasks. When the majority of validators agree on the task result quality, then the original worker receives a payment and a higher rating. Workers get a lower rating and no payment for rejected tasks.

Validators who approve a bad result, if present, are punished with a significantly reduced rating. Such a system does not discourage conscientious validators from being suspicious, because when they are right, they receive a higher rating. However, it does strongly discourage validators from accepting wrong results.

With validators motivated to accept good results and even more motivated to reject bad results, the best strategy for workers is to do their best and deliver correct results,while the best strategy for validators is to accept the correct results. Such behavior is a Nash equilibrium in this contrived game and payoff matrix.

We have several requirements for our rating and task validation system to be able to process task completion and validation in real time:

• Online calculations. We need to evaluate work results as they arrive using only data stored publicly in our Ethereum smart contracts and in our permissioned blockchain that is accessible to relevant task requesters and workers.

• Transparency. All rating changes and billing events should be visible to task requesters and workers online.

• Reproducibility. Calculations must be simple enough that an involved party can reproduce them independently.

• Aligned incentives. The system should motivate workers to behave diligently and conscientiously by providing a good reward and punishment balance.

Web application

The Dbrain web application integrated with Ethereum (DApp) provides an intuitive tool for data labeling and validation tasks for crowdworkers. The complex user interface allows crowdworkers to perform advanced tasks, such as image labeling for classification and regression, object annotation with bounding boxes and segmentation masks.
