sv-lib

sv-lib was a typescript lib Max wrote in 2018 for interfacing with SV Light (name of the blockchain backend we use).

It is useful as a reference for how to interact with SV Light, considering we'll need something v. similar in this app (either directly or as a library)

The following fork of my-ether-wallet is useful for interacting with the various on-chain contracts, too:

ballot spec stuff

v1

SecureVote used 2 versions; the first version was a bit more basic, had some redundant info (start/end) or unused fields (binding/not binding) and looked like this:

{
    "ballotVersion": 1,
    "ballotInner": {
        "ballotTitle": "Some Bill We Can't Show On Google",
        "shortDesc": "It's a bill worht banning you for!\nYup!",
        "longDesc": "Lots\nOf\nStuff\nHere\n\n[have implemented markdown](https://example.com) for it before with ease",
