An asset is any file of any size and format, the signature of a digital asset is created via RELY Track, the signature is a unique value for each resource that is created using a cryptographic hash function that accepts an input and returns an alphanumeric string of fixed size. The string is called a "hash value".
The process is one-way, which means that the certified document on the Blockchain cannot be reproduced by the hash value. If the document is changed the hash value changes. Therefore, if you get a hash value from the original document, you can always check the originality of the document by comparing the hash values. A match between the values means that the document is identical to the original, a mismatch between the hash values means that the document is different from the original, therefore NOT authentic!
Once a certification transaction has been performed in a public Blockchain network, the content cannot be forged, destroyed or modified and is therefore immutable.
