All you need to build Proof of Process apps.
What is Proof of Process?
Proof of Process (PoP) is a protocol that allows participants to trust a common process by immutably recording who did what, when and in which order.
This is accomplished through the creation of a cryptographic audit trail that records these key factual elements of every step of a process. It can be shared easily, independently verified, and thus provides a backbone of trust upon which participants in Proof of Process Networks can rely.
