Dbrain - Open Blockchain to Collectively Build AI Apps

What is Al ?

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.

What Is Dbrain ?

Dbrain is an open blockchain platform that links crowdworkers and data scientists enabling them to transform raw data into real-world AI solutions.

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,More info here https://dbrain.io/

Blockchain technology helps us meet many of AI’s current challenges. Using the blockchain, we can confidently manage high-quality data labelling, security concerns, intellectual property rights, and international micropayments. Using existing commercial computation infrastructure allows us to build an affordable, scalable toolkit for developing and deploying AI apps.

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.

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,https://whitepaper.dbrain.io/.

Blockchain and crypto

The Dbrain platform works on the Ethereum network and relies on its smart contracts. We’re building a scalable permissioned blockchain anchored to the Ethereum network via state channels. Our solution can securely process thousands of transactions per second which all involved parties can verify independently. We implement two blockchain protocols for decentralized access to our platform and an in-house cryptocurrency.

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.

PICARD protocol

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. The protocol allows data scientists to work on a contract basis as well as to contribute to community owned datasets and public kernels. It also allows participation in Kaggle-like competitions on openly listed challenges.

Dbraincoin (DBR)

Dbraincoin (DBR) is implemented as a standard ERC20 token. The total number of Dbraincoins in existence is fixed. We use our coins as an internal currency that participants use to pay and receive for work, data and AI application usage on the platform.

Product

The Dbrain web application integrated with Ethereum (DApp) allows every Internet user to perform tasks, earn Crypto and withdraw it with a single click. Telegram bot for simple data labeling and task validation gives us access to crowdworker audience with the least imaginable friction. Our upcoming mobile app will provide user interface for complex tasks on smartphones and tablets and allow to collect custom data from crowdworkers,please join us bountyhive.io/join/Dbrain

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.

Telegram bot

The Telegram Bot is ideal for simple image labeling and validation tasks. Anyone with the internet connected device can label data and get paid instantly with Dbraincoins. Smartphones are more accessible and widespread in developing countries than laptops, while internet penetration is high, which gives us an edge in accessing workers in those regions.

Mobile application

Mobile apps are a great tool to create new data — video, audio, photos, acceleration, GPS coordinates and touch input. Our app will allow any platform user to become a data provider and earn additional Dbraincoins.
