Photochain is a game-changing solution in the stock photography marketplace. The main idea behind the project is to enable all contributors to have control of all aspects of their work: price, copyrights, and licensing of their works.

Business challenge

Photochain was looking for reliable technological partners experienced in Blockchain development, who could help in advancing their platform to the market. The goal has been to bring innovation into the photo stocks market and eventually become the leader.

Business solution

We co-developed a web platform serving a photo stock marketplace offering low fees and fast transactions between parties. The current competition does not offer the aforementioned benefits, putting heavy fees on users. Photochain is the first of its kind to include a reliable and durable license system based on Blockchain. Every transaction leaves a trace on the Ethereum Blockchain and is unchangeable, meaning a user gains solid public proof of what she/he bought and owns. In order to attract users with a large photo base, the platform includes a user-friendly mass upload functionality, enabling an effortless transfer of their existing portfolios.

Product and main features:

  • Payments for licenses: Users buy photo licenses with either FIAT currency or ERC20 tokens, and the license is stored on the Blockchain.
  • Mass upload: The user uploads his portfolio directly from the web application.
  • FIAT payments: Processing FIAT payments with Stripe.
  • KYC: Full verification process.
  • Photo recognition: Photo content recognition and filtering NSFW content with the Clarifai platform.
  • Duplicate identification: Identifying photo duplicates.
  • Tagging: Automatic tagging with Clarifai.
