Complete tamper-proof history of every document action. Who stamped it, who verified it, when, and where — cryptographically linked for absolute integrity.
A complete history of everything that happens to your document
When stamp was applied, by whom, which stamp template
Every verification attempt with timestamp and result
When document was accessed through verification link
When verification link was generated or shared
When verification certificate PDF was downloaded
When document hash was anchored to blockchain
Each custody record is cryptographically linked to the previous one. If anyone tries to tamper with, delete, or reorder records, the chain breaks and tampering is detected.
