ePrint Report: LedgerLocks: A Security Framework for Blockchain Protocols Based on Adaptor Signatures

Erkan Tairi, Pedro Moreno-Sanchez, Clara Schneidewind

The scalability and interoperability challenges in current cryptocurrencies have motivated the design of cryptographic protocols that enable efficient applications on top and across widely used cryptocurrencies such as Bitcoin or Ethereum. Examples of such protocols include (virtual) payment channels, atomic swaps, oracle-based contracts, deterministic wallets, and coin mixing services. Many of these protocols are built upon minimal core functionalities supported by …
