Smart Contracts, Bitcoin Bots, and Consumer Protection
Social Science Research NetworkTrustless public ledgers (“TPLs”)—the technology underneath Bitcoin—do more than just create online money. The technology permits people to directly exchange money for what they want, with no intermediaries, such as credit card companies. Contract law is

Finding permission bugs in smart contracts with role mining
International Symposium on Software Testing and Analysis, 2022Smart contracts deployed on permissionless blockchains, such as Ethereum, are accessible to any user in a trustless environment. Therefore, most smart contract applications implement access control policies to protect their valuable assets from ...

European Review of Private Law, 2018
Abstract: The computer language (computer code) on the basis of which smart contracts are written is different from the natural (Human) language. Computer language is a ‘dry’ language, whereas natural language is ‘wet’. In other words, it means that computer language is deterministic (just one meaning and one result are conceivable), when natural ...

ZeeStar: Private Smart Contracts by Homomorphic Encryption and Zero-knowledge Proofs
IEEE Symposium on Security and Privacy, 2022Data privacy is a key concern for smart contracts handling sensitive data. The existing work zkay addresses this concern by allowing developers without cryptographic expertise to enforce data privacy. However, while zkay avoids fundamental limitations of
