Abstract

In the Zendoo white paper we introduced a novel sidechain construction for Bitcoin-like blockchains, which allows a mainchain to create and communicate with sidechains of different types without knowing their internal structure. In this paper, we take a step further by introducing a comprehensive method for sidechains to communicate amongst each other. We will also discuss the details of a cross-chain token transfer protocol that extends the generic communication mechanism. With the cross-chain token transfer protocol, it can enable a broad range of new applications, such as an exchange platform, that allows the ability to trade tokens issued from different sidechains.
