Mimblewimble is a cryptocurrency protocol with good privacy and scalability properties. A trade-off of Mimblewimble is the requirement that transactions are interactive between sender and receiver. TariScript is presented as an extension to Mimblewimble that adds scripting capabilities to the protocol. We describe the theoretical basis for TariScript and present the modifications required to make it secure. The trade-offs and use cases for TariScript are briefly covered.
