Visualization of Cross-Chain Transactions for Secure Blockchain Interoperability (Position Paper)

In the last decade, blockchain interoperability solutions, especially cross-chain bridges, have become increasingly popular. However, the field still has considerable room for growth in addressing vulnerabilities and preventing system exploitation. In this work, we propose a novel classification scheme for evaluating and benchmarking blockchain interoperability visualization mechanisms and identifying key gaps on cross-chain information availability. We also propose two mechanisms to streamline the cross-chain operation analysis process. The first is a dataset generation framework for cross-chain transactions that can fetch blockchain events from blockchains, aggregate them into cross-chain transactions, and record these transactions in an organized format for data analysis. The second is a visualization tool that shows users information on cross-chain operations based on an existing dataset. This position paper aims to bring to light and address gaps in blockchain interoperability with the intention of enabling and catalyzing the development of future solutions, ultimately contributing to a more mature blockchain interoperability ecosystem.
