kandi X-RAY | victor Summary
Victor, familiar name in cryptography to denote VERIFIER, serves to publicly timestamp hash fingerprints of files. We may need to certify that a document existed on a particular date (e.g. for copyright or patent purposes). If the certification process can take place publicly that would certainly add veracity to the matter. GitHub can be used to perform as a trusted timestamping service. A git repository is designed in such a way that it is impossible to change a single bit of its content without that change becoming apparent in the commit identifiers (SHA-1). The explicit time of a commit is recorded by git, although it relies on the accuracy of the system's local clock.

I have created a sample angular app. Below are the details. Even the image is there inside the assets folder. It is getting copied directly under dist. This way, its getting duplicated which also causes build size increase.
