An AMM minimizing user-level extractable value and loss-versus-rebalancing
Conor McMenamin, Vanesa Daza
We present V0LVER, an AMM protocol which solves an incentivization trilemma between users, passive liquidity providers, and block producers. V0LVER enables users and passive liquid…
Private, Anonymous, Collateralizable Commitments vs. MEV
Conor McMenamin, Vanesa Daza, Xavier Salleras
In this work, we introduce the private, anonymous, collateralizable commitments (PACCs) framework. PACCs allow any smart contract wallet holder to collateralize a claim, request, o…
An Automated Market Maker Minimizing Loss-Versus-Rebalancing
Conor McMenamin, Vanesa Daza, Bruno Mazorra
The always-available liquidity of automated market makers (AMMs) has been one of the most important catalysts in early cryptocurrency adoption. However, it has become increasingly…
Price of MEV: Towards a Game Theoretical Approach to MEV
Bruno Mazorra, Michael Reynolds, Vanesa Daza
Maximal (also miner) extractable value, or MEV, usually refers to the value that privileged players can extract by strategically ordering, censoring, and placing transactions in a…
Marvel DC: A Blockchain-Based Decentralized and Incentive-Compatible Distributed Computing Protocol
Conor McMenamin, Vanesa Daza
Decentralized computation outsourcing should allow anyone to access the large amounts of computational power that exists in the Internet of Things. Unfortunately, when trusted thir…
FORT: Right-proving and Attribute-blinding Self-sovereign Authentication
Xavier Salleras, Sergi Rovira, Vanesa Daza
Nowadays, there is a plethora of services that are provided and paid for online, like video streaming subscriptions, car or parking sharing, purchasing tickets for events, etc. Onl…
FairTraDEX: A Decentralised Exchange Preventing Value Extraction
Conor McMenamin, Vanesa Daza, Matthias Fitzi +1
We present FairTraDEX, a decentralized exchange (DEX) protocol based on frequent batch auctions (FBAs), which provides formal game-theoretic guarantees against extractable value. F…
Do not rug on me: Zero-dimensional Scam Detection
Bruno Mazorra, Victor Adan, Vanesa Daza
Uniswap, like other DEXs, has gained much attention this year because it is a non-custodial and publicly verifiable exchange that allows users to trade digital assets without trust…
Clover: an Anonymous Transaction Relay Protocol for the Bitcoin P2P Network
Federico Franzoni, Vanesa Daza
The Bitcoin P2P network currently represents a reference benchmark for modern cryptocurrencies. Its underlying protocol defines how transactions and blocks are distributed through…
AToM: Active Topology Monitoring for the Bitcoin Peer-to-Peer Network
Federico Franzoni, Xavier Salleras, Vanesa Daza
Over the past decade, the Bitcoin P2P network protocol has become a reference model for all modern cryptocurrencies. While nodes in this network are known, the connections among th…
Achieving State Machine Replication without Honest Players
Conor McMenamin, Vanesa Daza, Matteo Pontecorvi
Existing standards for player characterisation in tokenised state machine replication protocols depend on honest players who will always follow the protocol, regardless of possible…
SANS: Self-sovereign Authentication for Network Slices
Xavier Salleras, Vanesa Daza
5G communications proposed significant improvements over 4G in terms of efficiency and security. Among these novelties, the 5G Network Slicing seems to have a prominent role: deplo…
Improving Bitcoin Transaction Propagation by Leveraging Unreachable Nodes
Federico Franzoni, Vanesa Daza
The Bitcoin P2P network is at the core of all communications between clients. The reachable part of this network has been explored and analyzed by numerous studies. Unreachable nod…
