As a user, I also want a hash of the notes stored on Ethereum, so I can prove that I wrote them when I did and that nobody has tampered with them since.

Acceptance

There is a smart contract
The smart contract is tested
A new smart contract instance is created at login

Assuming a single contract for the whole app, the contract will store a tuple of:

uint256 (content hash) => { address: tx.origin, uint256: block.timestamp }
