hashchain - Python data certification


hashchain is a Python package developed to join the ease of use of Python with the security of blockchain to certify that your important records haven’t been tampered with.

The core module creates a hash chain, attesting that no record can be tempered with, once saved. The blockchain module save a proof of your hashchain permanentely in the most secured way. Then, it’s impossible to alter the haschain without causing a discrepancy with the blockchain.

No need for third party certification anymore. No more single point of failure nor certification costs.


The package is in beta release Even though No major change to the hashing mechanism should be expected, we can’t provide any kind of grantee. Use it in a production environment at your own risk.
