Use blockchain to timestamp proof documents stored in Activescale

  • Internship
  • API
  • Blockchain


In some industries it is required to be able to proof that a certain document (or a version of it) existed at a specific moment in time and has not been modified since then. If the number of documents is relatively low this can be solved by registering documents with a government institution (e.g., patent bureau), a notary, etc. But this is not scalable and potentially costly. Blockchain technology allows to make this proof publicly verifiable without the need of a middleman.

Possible use cases:

  • Document timestamping;
  • Guarantee data integrity and proof provenance
  • Regulatory compliance (SEC 17a-4, Sarbanes-Oxley, HIPAA,…).

https://chainpoint.org offers an API to hash documents, timestamp proof the hash and anchor it to a blockchain. This needs to be integrated with ActiveScale to process newly written documents with the chainpoint API and attach the received proof to the documents.

The following tasks are proposed:

  • Investigate chainpoint API’s and ActiveScale API’s
  • Describe in detail the complete data flow:
    • New object written
    • Hashed, time proofed, anchored in blockchain
    • Associate proof with document
    • Third-party verification process
  • Develop a working prototype


  • Blockchain
  • Apache Kafka
  • Java
  • Python
  • Linux


  • 6-week internship
  • Between July & September, you can choose when.
  • Degree: Master Of Science - Computer Engineering.
