v0.3.0 1 year, 7 months ago .tar.gz browse log

tallyard v0.3.0

This release is very substantial.  We've moved off of libp2p entirely and onto
the federated Matrix messaging network.  This obviously took a huge amount of
effort (and many weekends), but it was well worth it because Matrix gives us
many things, including

1. authentication, which (once the zkproofs implementation is finished) solves
   the problem of double-voting,

2. an easy way to find elections and limit who can join them by using Matrix
   rooms, and

3. a simple RESTful HTTP API [0] to propagate messages between voters, replacing my
   ad hock peer-to-peer solution.

I have nothing against libp2p; it is clearly very capable and I look forward to
seeing what that project becomes.  I'm grateful that I got to play with it for a
few months when working on tallyard.  However, I want tallyard, specifically, to
focus on being a system with strong homomorphic secret-sharing and
zero-knowledge proofs; these directly address the problems I'm trying to solve.
Learning the ins and outs of peer-to-peer networking was too much of a load for
me (especially for debugging).  With Matrix, we're able to stand on the
shoulders of giants and solve a whole bunch of problems like the aforementioned,
and a bunch of little things like rate-limiting, end-to-end encryption, backups,
etc. with little to no effort.  Also, the fully peer-to-peer dream seems to be
on the horizon with P2P Matrix [1].

This release also completely changes the look and behavior of messages in the
protocol.  Messages are now versioned to facilitate future protocol upgrades,
which will be necessary for the zkproof changes.  Messages also now require
references (in the form of event IDs) to previous messages to ensure the correct
ordering of events and to protect against a handful of replay attacks.

Much work is yet to be done, so I'll see you in the next release.
