Immediate "To Do" Items (Oct.26th)

[who-biz]

1.) Add idle handler for cleaning pending ntzpool. There should not be two pending ntz's in the pool at a given time. Should be simple enough to write in some extra rules to the refresh or update_pool RPC calls. Done : 2 Nov

2.) Existing idle handler needs to properly fetch pending ntz from the pool w/ metadata rather than relaying a NOTIFY_REQUEST_NTZ_SIG unconditionally.
Done: 30 Oct

3.) Make sure that invalid signature error has been cleared up. (follow-up on e15fecc)
- Also clean up the existing res.tx_metadata_list response that is fed into a request_ntz_sig wallet call. We really shouldn't need to handle the metadata list as a list, and should be able to change this to a string. It is one contiguous hex blob currently, so a list with one element.
Done: 30 Oct

4.) Make sure that what is being done with checking the identity element & viewkeys is acceptable means for verifying sender is a notary node. This might not be a sufficient check for integrity due to the surjective nature of the function, and problem could arise due to being 'right-invertible'. This is a problem, if I am understanding correctly, since we could recover using a pre-image ... unsure of implications here EDIT: Probably only the case with deterministic viewkeys.

5.) Pending-tx-specific hash needs stored for database retrieval of the ptx_blob. Added a function in notary_server.cpp to calculate the hash and pair it with the ptx_blob. Rest of functions in flow from wallet -> rpc -> core -> blockchain -> db need modified to pass the hash through with the blob. Done: Oct 31

6.)Bring README.md up to speed (Mostly Done: 3 Nov), and add code flow document, for easier comprehension. Should go a long way in making things easier for those in KMD/ZEC ecosystem, in particular.

7.) Ensure that check against notary pubkeys also occurs daemon-side and not solely on wallet side. Need to look into further, but pretty sure that we currently lack verification in daemon. Maybe consider adding to blockchain as well.
