Bitcoin Private Key Locked Transactions

Sergi Delgado-Segura and Cristina Pérez-Solà and Jordi Herrera-Joancomartí and Guillermo Navarro-Arribas

Abstract: Bitcoin smart contracts allow the development of new protocols on top of Bitcoin itself. This usually involves the definition of complex scripts, far beyond the requirement of a single signature. In this paper we introduce the concept of private key locked transactions, a novel type of transactions that allows the atomic verification of a given private key (belonging to an asymmetric key pair) during the script execution.
