Graviton: interchain swaps and wrapped tokens liquidity incentivisation solution

Abstract

This paper discusses the issues with liquidity that inhibit adoption of so-called wrapped tokens, i.e. digital assets issued in one blockchain ecosystem (origin) with representation in other blockchain networks (destination), and an incentive model and a governance mechanism for solving these issues are suggested. The proposed liquidity model called Graviton can be implemented both within the framework of a single destination chain, or as a blockchain-agnostic solution combining various blockchain platforms together and providing liquidity to wrapped tokens in each of them. This model does not depend on how cross-chain transfer gateways are implemented, and can work with both centralized gates and bridges, or decentralized trustless gateways, as well as gateways based on oracle networks and threshold signatures.
