zkSHIELD – A Web-Based Cross-Chain Zero Knowledge Asset Proof

Abstract

The global transition towards Web3 is giving rise to many blockchain networks, each with its native cryptocurrency. Ethereum is used for decentralized applications, Bitcoin is used for investment, and Polygon is used for scalability solutions. Furthermore, a few well-known blockchain platforms have implemented interoperability features, meaning users can now send wrapped tokens around different blockchains. User assets are then distributed across multiple blockchain networks and wallets. This means user assets are already distributed across multiple tokens on different blockchain networks. This work presents a web application that allows you to visualize your assets distributed across different blockchain networks and wallets. Notably, this work supports the straightforward integration of secondary wallets with user accounts. In addition, this work supports tracking the historical user asset transfer requests, including incoming and outgoing ones, and storing the metadata associated with each asset transfer, including its corresponding proof’s Content Identifier (CID) after zkSNARKs proof generation by hosting it on the InterPlanetary File System (IPFS).
