Description
Weaver, a Hyperledger labs, project, is a DLT interoperation framework that supports data sharing, asset exchange and asset transfer between blockchain networks built on independent DLTs while preserving core blockchain tenets of decentralization of the participating blockchains and without relying on trusted mediating individuals or networks. True interoperability of tokens among different networks, whether they are built on permissoned or open blockchain technology, requires standards around tokens so that they can be exchanged or transferred across network boundaries in a way that is independent of the underlying DLT implementation. The Enterprise Ethereum Alliance (EEA) has made significant strides in this direction by drafting ERC (Ethereum Request for Comments) standards for managing different types of assets. The widely used ERC-20 standard helps manage fungible token types, whereas ERC-721 and ERC-1155 standards help manage non-fungible token (NFT) types and multi-token types respectively.
The scope of this project covers interoperation support for these three prominent ERC token types across Hyperledger Fabric, Corda and Hyperledger Besu networks. Weaver currently supports interoperation between ERC-20 token types for Hyperledger Besu networks. The goal of this project is to add support for ERC-721 and ERC-1155 standards for interoperation among Hyperledger Besu networks, and extend support for ERC-20, ERC-721 and ERC-1155 token types to interoperate across all three DLT platforms supported by Weaver i.e., Hyperledger Fabric, Corda and Hyperledger Besu.
