Nathan Spataro and Max Kaye have created the SecureVote ( platform that provides security, integrity and anonymity of voting using cryptography and blockchain technology.

Max will be explaining, answering questions, and discussing how their digital secret digital ballot works. And they claim that it is the only highly scalable, trustless, fully p2p vote anonymisation algorithm known. Discussion on evoting in general is welcome.

And according to time and demand we'll also discuss smart contract architecture for complex, upgradable systems - with examples.

If you're curious, see the 18 month old post on SecureVote's vote anonymisation. There has been further improvements since then but is pretty accurate.

tl;dr is a double round oblivious shuffle similar to how its used in coinshuffle

You can find SecureVote's smart contracts at .

As usual, please bring your laptop along as this session may involve some practical work.
