Helper to certify database entries, using hashchains and blockchains
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.
