Towards an internet of blockchains: decentralized discovery services with layer 2 ceremonies

Abstract

The rise of heterogeneous blockchain platforms that are utilized by various organizations depending on their needs has created an interoperability problem. While significant progress has been made in enabling interoperability between blockchain networks, most works in this area assume that these networks are already aware of each other. This thesis makes two key contributions to fill this gap. First, it introduces a decentralized architecture for inter-blockchain network and asset discovery that allows domain registration and resolution without dependence on a central authority. The system is self-sufficient, scalable, and enables dynamic discovery across blockchain networks. Second, it presents a decentralized mechanism for generating trust anchors through multi-party cryptography ceremonies. By increasing the number of participants constructing Common Reference Strings (CRS) and periodically regenerating it, the mechanism enhances the security of zero-knowledge systems while maintaining their decentralization. The evaluation of both implementations shows that the discovery architecture achieves high throughput under heavy load and scales efficiently with the number of participants. Similarly, the trust anchor generation mechanism performs resilient CRS generation ceremonies within bounded durations.
