The team behind Boquila, a proof of concept to obscure identifiable information from third-party websites, took the top spot at this year’s hackathon. We sat down with Mariarosaria Barbaraci and Jayamine Alupotha, two members of the winning team, to talk about what they built and their experience at this year’s IC3 Blockchain Camp.

In a three part series, we look at the “Snow” protocols that address the fundamental consensus problem and were introduced in a whitepaper by a group associated with AvaLabs that pioneered the Avalanche blockchain infrastructure. This is a post that consists of three parts. Part 1 appears here, part 2 and part 3 appear on the Crypto@Bern blog. This first part gives an overview of these Snow protocols and a summary of our findings.

The problems of maximal-extractable value (MEV) and front-running attacks have plagued decentralized finance (DeFi) in the recent years. We tackle the problem of sandwich attacks in general and introduce a protocol to transform any blockchain consensus algorithm into a new one that has the same security, but in which sandwich attacks are no longer profitable. Our protocol is fully decentralized with no trusted third parties or heavy cryptographic primitives. It makes existing blockchains resilient to such attacks in exchange for increased latency until consensus becomes final and by adding a small computational overhead.

PROF: Protected Order Flow in a Profit-Seeking World

Users of decentralized finance (DeFi) applications face significant risks from adversarial actions that manipulate the order of transactions to extract value from users. Such actions—an adversarial form of what is called maximal extractable value (MEV)—impact both individual outcomes and the stability of the DeFi ecosystem. MEV exploitation, moreover, is being institutionalized through an architectural paradigm known Proposer-Builder Separation (PBS). This work introduces a system called PROF (Protected Order Flow) that is designed to limit harmful forms of MEV in existing PBS systems. For further details, please check out our Projects Page.
