Interview with Joris Schellekens, software developer at iText, about PDF Days Europe 2018


Joris Schellekens, software developer at iText

PDF Association: At the PDF Days Europe, you will be hosting a presentation titled “Blockchain and Distributed Ledger Technology for documents” – what’s that about?

Joris Schellekens: Blockchain is a type of DLT in which records are organized in blocks that are appended to a single chain using cryptography and distributed consensus. Each block contains a time stamp and a link to the previous block, ensuring that data in a block can’t be altered retroactively. This makes blockchain a good choice for the recording of events, provenance tracking, and document life-cycle management. Signing a PDF in the blockchain instead of storing a signature in a PDF reduces the complexity of the code for a developer who needs digital signing and verification functionality. The same principle can be used in many other use cases to implement a document workflow, to keep track of the location of a document, and much more.

PDF Association: Who is your presentation aimed at?

Joris Schellekens: The presentation aimed at both developers (there is substantial technical content), and decision makers (there is “food for thought” that may be useful, even without full understanding of the technical details).

PDF Association: What will the people who attend your presentation be able to take away from it?

Joris Schellekens: The main take-away is that blockchain is more than a digital coin. And it offers certain opportunities that can offer real value.
