Tutorial

Here is another great tutorial.

Using Proofivy

You calculate a hash of your file using our Streamlit app or CLI app,

proofivy Driving\ Data.xlsx
bafkr4ifmrahhc26dsi5ot2g445lixyd6477wdlx6xagb6hvxtyv2ly4omm

and add it to Proofivy using the web interface. Since you are a member it does not cost you anything except gas (network costs).

On the block explorer you can find your commit.

Use this Jupyter notebook to check onchain data.

There is also a message posted on Proofivy describing the commit.
