What am I looking at?
This is a certificate of registration. The item below was registered in the EverVerify public registry by its owner. Registration creates a permanent, tamper-evident record of what the item is, what its photographs look like, who registered it, and when.
What is a SHA-256 fingerprint? A unique digital fingerprint computed from a photo's exact contents. Change even one pixel and the fingerprint changes completely. If a file in your possession produces the same fingerprint, it is bit-for-bit the registered original.
What is a receipt? Every registration is sealed as a signed entry in a chain, where each entry locks in the one before it — like pages in a notary's ledger that cannot be quietly rewritten. The receipt code shown is that entry's identifier in the chain.
