ring-multisig v0.1.0

Ring Signatures based anonymous voting

(Barreto-Naehrig 256 bit Elliplic Curve)

Presentation in Google Slides

User story:

• Roles: judge, juries

1. Judge publishes a decision on some topic, f.e "Death sentence hearing on case #01232"
2. Judge publishes M public keys of juries and number N: N <= M - amount of needed votes "for"
3. Each jury:
   • generates message, voting "for" or "against" judge's decision
   • generates ring-signature for this message, using public keys of other juries
   • sends transaction with ring-signature to contract
4. Contract collects each correct signature, and increases number of votes "for" if all ok
5. If N votes "for" is reached, action is performed

It's planned to implement this ring-signing as a library, to use with any solidity function

Elevator Pitch

dApp to anonymously vote on critical decisions (euthanasia, death senstence, etc.) using BN256 ellicptic curve

Inspiration

We want to solve problem of critical decision making and unability to gurantee privacy of those collective decisions.

What it does

dApp allows judge to create a new proposal and nominate juries who in turn can cast votes using their respective private keys. Prosopal creator specifies criteria for decision to be enforced (N of M signatures). Juries cast their votes that are counted by smart contract preserving full privacy.
