Latus Incentive Scheme: Enabling Decentralization in Blockchains based on Recursive SNARKs

Abstract: In the Zendoo whitepaper we introduced a novel SNARK-based construction that allows Bitcoin-like blockchains to create and communicate with sidechains of different types without knowing their internal structure. We also introduced a specific construction, called Latus, allowing creation of fully verifiable sidechains. In the paper we omitted a detailed description of an incentive scheme for Latus that is an essential element of a real decentralized system. This paper fills the gap by introducing details of the incentive scheme for the Latus sidechain. The represented ideas can also be adopted by other SNARK-based blockchains to incentivize decentralized proofs creation.
