DataNexus Marketplace

DataNexus bridges the gap between companies seeking alternative data sources and individuals looking to monetize their personal information. Our platform allows data seekers to specify their needs, prompting users to contribute relevant personal data to a collective pool. This highly secure, encrypted, and decentralized data pool becomes a rich source of nuanced insights once merged.

DataNexus provides access to detailed, individualized information that could enhance the predictive abilities of AI models at scale. And unlike traditional data brokers, our platform ensures each participant is fairly compensated while fully protecting privacy through encryption.

By forging connections between data demand and supply in a secure, transparent, and decentralized manner, DataNexus pioneers a new data marketplace – one that finally puts power back into the hands of individuals. Our solution transforms how data is traded in the digital age.

Our platform enables seamless, secure data transactions between purchasers and providers.

Purchasers create Data Listings detailing their desired data. Providers then sell their data by sending encrypted API Data keys to the Listing contract. This triggers a chain of automated steps:

1. The DataListing contract decrypts the provider's API key using a Functions script.

2. It fetches the provider's API data and encrypts it with the purchaser's key.

3. The encrypted data is posted to IPFS for the purchaser to access. This workflow allows providers to share access without ever exposing their API keys.

Purchasers can only view the data they purchased. The entire transaction happens securely on-chain.
