## MINI-FE: computing functions on private data without trusted parties

In this blog post we introduce MINI-FE, a cryptographic protocol to compute functions over private data without any trusted parties and with minimal interaction. In particular we present its applications for Private Stream Aggregation and Quadratic-like Boardroom Voting.

## BatRaVot: Scalable Trustless Voting on Ethereum

BatRaVot is a trustless voting protocol that allows for both on-chain and off-chain voting with on-chain results, making it a cost-effective and versatile solution for various types of voting scenarios on the Ethereum blockchain. In the blog post we explain the protocol and present our implementation that you can already use today.

## A Rust implementation of DualRing's sum argument

Recently at Aragon we've been looking for ways to enable efficient, decentralised private voting. As part of that, we've been looking into the state of the art of private linkable membership proofs, as they're very suitable to act as the base of a private voting protocol. We implemented an interesting subsection of the state of the art in ring signatures, and this post explains why that's interesting!

## Decentralised Private Voting

Many private voting protocols rely on central servers, or partially or fully trusted third parties, either for availability or for privacy. This note discusses some ways to achieve decentralised, private, blockchain-based voting, without any trusted third parties.

## Simple Soundness Proofs

Soundness proofs tend to be quite long and technical. We describe a general method to significantly simplify such proofs if some specific conditions are met.

## Weil reciprocity on the projective line

This Maths Seminar note provides a self-contained proof of the Weil reciprocity on the projective line of a field, together with concrete examples. A good grasp of the concepts explained here will help with understanding elliptic curve pairings.
