We all know blockchain because it's the technology used by Bitcoin in the context of cryptocurrency. "Virtual money" or "Digital currency" is only one application of Distributed Ledger Technology (DLT). At iText, we've developed a series of patents that describe mechanisms:

  • to ensure document integrity, authentication, and non-repudiation,

  • to provide long-term validation, and

  • to manage document identification and retrieval.

We've been evangelizing these mechanisms at events such as:
