Gravity: a blockchain-agnostic cross-chain communication and data\n oracles protocol

Abstract

This paper intends to propose the architecture of a blockchain-agnostic\nprotocol designed for communication of blockchains amongst each other (i.e.\ncross-chain), and for blockchains with the outside world (i.e. data oracles).\nThe expansive growth of cutting-edge technology in the blockchain industry\noutlines the need and opportunity for addressing oracle consensus in a manner\nboth technologically and economically efficient as well as futureproof.\nBlockchain-agnosticism is inherently limited if proposing a technological\nsolution involves adding one more architectural layer. As such, Gravity\nprotocol is designed to be a truly blockchain-agnostic protocol. By ensuring\nparity through direct integration and by leveraging the stability and security\nof the respective interconnected ecosystems, Gravity circumvents the need for a\ndedicated, public blockchain and a native token. Ultimately, Gravity protocol\nintends to address scalability challenges by providing a solid infrastructure\nfor the creation of gateways, cross-chain applications, and sidechains. This\npaper introduces and defines the concept of Oracle Consensus and its\nimplementation in the Gravity protocol named the Pulse Consensus algorithm. The\nproposed consensus architecture allows Gravity to be considered a singular\ndecentralized blockchain-agnostic oracle.\n
