As answered by people managing StackGo and StampR.eu.
StampR.eu's answer:
Web application, SHA-256 cryptographic hashing, electronic timestamping, PDF certificate generation, QR-based verification and server-side certificate verification infrastructure.
StampR.eu's answer:
StampR combines an authorship declaration for a specific digital work with the SHA-256 fingerprint of that exact file version and a verifiable electronic timestamp. The result is a certificate that documents what was certified, who declared authorship, and when that specific version was recorded. Certificates include a unique identifier and can be checked through StampR’s verification workflow.
StampR.eu's answer:
StampR is designed for people who want a simple way to create verifiable evidence before sharing digital work. It focuses on the exact file version being certified, uses cryptographic fingerprinting, provides a downloadable certificate, and supports independent verification. It also avoids presenting the service as copyright registration: copyright exists independently, while StampR creates evidence around authorship declaration, file identity, and time.
StampR.eu's answer:
StampR is primarily for creators, freelancers, professionals and organizations that need to document a digital work before sharing it externally. Typical use cases include music, photography, design, written works, source code, research, concepts, drafts and other digital files where proving the existence of a specific version at a particular time can be useful.
StampR.eu's answer:
StampR was built around a practical problem: digital work is often shared with clients, collaborators, publishers or platforms before there is a clear, independently verifiable record of the exact version that existed beforehand. StampR turns that step into a straightforward workflow by combining file fingerprinting, an authorship declaration, timestamp evidence and a certificate that can later be verified.
