documents module allows a user to share a document to other users.
Then, the receivers can send back to the sender a receipt proving that they have seen the document.
- We are not actually sharing Documents on a blockchain.
- We are sharing a transaction on a blockchain with a document footprint (HASH)
An hash is the output of a hashing algorithm like SHA (Secure Hash Algorithm). These algorithms essentially aim to produce a unique, fixed-length string – the hash value, or “message digest” – for any given piece of data or “message”.
As every electronic file is just data that can be represented in binary form, a hashing algorithm can take that data and run a complex calculation on it and output a fixed-length string as the result of the calculation.
The result is the file’s hash value or message digest.
'Sharing a Document' on Commercio.network means sending a shareDoc transaction on a blockchain with your document hash.
# ShareDoc real world use cases
- Legally prove a document was shared with a third party
