Project Goal:

Our goal is to create a user-friendly and secure AI marketplace that facilitates the buying and selling of datasets and pre-trained ML models. Our platform also offers coding capabilities for the users and empowers decentralized computation to process their machine-learning models. We aim to establish a vibrant community of data providers, model developers, and users, offering a diverse range of high-quality resources for various domains using blockchain technology.

We are adding more features like Data Visualization, Commenting Features in individual datasets and Models, Email notification for completion of Computation Job and Plagiarism Checker to avoid duplicity of the dataset. These features will enhance the user experience.

Through Pravahini, we aim to foster collaboration, innovation, and knowledge-sharing among data enthusiasts and researchers, driving ground-breaking advancements in AI and data-driven applications.

Project Value:

Benefits of Pravahini on Blockchain:

Secure Marketplace Functionality: Blockchain ensures a secure and transparent marketplace for buying and selling datasets and pre-trained ML models. Transactions are tamper-proof, enhancing trust.

Efficient Decentralized Computation: Leveraging blockchain, Pravahini optimizes ML model processing through the Bacalhau Protocol. Users harness the power of distributed systems for resource-intensive tasks.

Granular Access Control: The Lighthouse Protocol enforces secure access control, allowing users to define permissions. This protects sensitive data and resources from unauthorized access.

Transparent Revenue Sharing: Smart contracts facilitate transparent revenue sharing with data providers and model creators. This creates a fair and collaborative ecosystem, incentivizing quality contributions.

Project Info:

In Sanskrit, the term “प्रवाहिनी” (Pravāhinī) embodies the essence of a “flow” or “stream.” Within our platform, it symbolizes the continuous flow of data, models, and innovations powering the realm of artificial intelligence. Pravahini is not just a marketplace; it’s a dynamic ecosystem fostering the evolution of AI resources.

welcome to hackathon season 6
Pravahini’s focus on decentralized computation is intriguing.
Please I have some important questions

Q1 Can you elaborate on how you plan to incentivize users to contribute computing power to the network.

Q2 How will you balance fair compensation for contributors with keeping costs attractive for buyers of processing power.


@Gordian @Prince-Onscolo @manfred_jr @MasterShadow007 @Andreaxino @Beast @ines_valerie @Relate101

Hello and thank you for the warm welcome to Session 6! We’re truly grateful for the recognition of our previous success in Session 5, and we’re excited to provide you with updates on our progress.

Regarding the latest developments, we’ve been hard at work refining our platform, Pravahini, to ensure it goes beyond being just another MVP. Our goal is to create a truly valuable resource for the community, which is why we’ve dedicated a significant amount of time to visiting universities and engaging with professionals already active in this domain. These interactions have provided invaluable insights that have guided our efforts in implementing new features aimed at enhancing the user experience and security of Pravahini.

Some of the key features which we are adding that includes Data Visualization, Commenting Features for individual datasets and models, Email notifications for completion of Computation Jobs, and a Plagiarism Checker to maintain data integrity. These additions reflect our commitment to building a platform that not only meets but exceeds the expectations of our users.

In addition, we are actively researching ways to improve the feature of decentralized computation. Our aim is to optimize the usage of Bacalhau Protocol to further enhance the efficiency and scalability of ML model processing through distributed systems.

While we haven’t created our social media handles just yet, we’re actively planning to do so once our project is fully developed and ready for public feedback.

As for the question about our platform’s activity and user base, while we’re still in the development phase, we’re confident that the features we’re implementing will attract users seeking a secure and user-friendly AI marketplace and decentralised computations.

Regarding the future expansion of our platform, we’re definitely open to exploring opportunities beyond datasets, ML models and de-computation . Our ultimate goal is to create a dynamic ecosystem that fosters collaboration, innovation, and knowledge-sharing among data enthusiasts and researchers. As the project evolves, we’ll be looking for ways to expand and enhance the offerings of Pravahini to better serve the needs of our users.

Thank you once again for your support, and we look forward to sharing more updates with you soon!


alright, thanks for the update

Team pravahini thanks for the update.


Hi @Okorie!

Thank you for the warm welcome. So Our platform does not rely on users contributing computation power. Instead, we generate revenue from computation tasks performed by the user on our platform.

Alright, keep us posted. Thank you


Thank you @Youngyuppie for your warm welcome and for acknowledging our achievement in the previous season.

A portion of the $15k prize money was utilized during the hackathon itself, allowing us to devote our full-time efforts to developing and refining Pravahini. Post hackathon, we allocated some part of the funds for conducting primary research by visiting Universities to gather feedback on enhancing our project’s features and functionalities based on user needs. The remaining funds were split between sustaining the project since the previous hackathon and reserving a part for further development, research, and sustaining the project moving forward.

We are committed to making the most effective use of these funds to create an impactful and innovative solution through Pravahini.

It’s nice to read about your progress in developing Pravahini and collaborating with experts and universities to gain insights.

Your focus on improving decentralized computation using the Bacalhau Protocol is exciting. Can you elaborate on any specific tweaks or enhancements you’re considering to improve efficiency and scalability?
