BitPriv: A Privacy-Preserving Protocol for DeFi Applications on Bitcoin
Ioannis Alexopoulos, Zeta Avarikioti, Paul Gerhart, Matteo Maffei, Dominique Schröder
Applications
Bitcoin secures over a trillion dollars in assets but remains largely absent from decentralized finance (DeFi) due to its restrictive scripting language. The emergence of BitVM, which enables verification of arbitrary off-chain computations via on-chain fraud proofs, opens the door to expressive Bitcoin-native applications without altering consensus rules. A key challenge for smart contracts executed on a public blockchain, however, is the privacy of data: bid privacy is crucial in auctions,...
chainBoost: A Secure Performance Booster for Blockchain-based Resource Markets
Zahra Motaqy, Mohamed E. Najd, Ghada Almashaqbeh
Cryptographic protocols
Cryptocurrencies and blockchain technology provide an innovative model for reshaping digital services. Driven by the movement toward Web 3.0, recent systems started to provide distributed services, such as computation outsourcing or file storage, on top of the currency exchange medium. By allowing anyone to join and collect cryptocurrency payments for serving others, these systems create decentralized markets for trading digital resources. Yet, there is still a big gap between the promise of...
Multi-Currency Ledgers
Joachim Zahnentferner
Applications
This paper extends an abstract formal model of UTxO-based and account-based transactions to allow the creation and use of multiple cryptocurrencies on a single ledger. The new model also includes a general framework to establish and enforce monetary policies for created currencies. In contrast to alternative approaches, all currencies in this model exist natively on the ledger and do not necessarily depend on a main currency. In comparison to non-native approaches based on scripts and smart...
