Hermes: Fault-tolerant middleware for blockchain interoperability

Blockchain interoperability reduces the risk of investing in blockchain systems by avoiding vendor lock-in, enabling a new digital economy, and providing migration capabilities. However, seamless among enterprises requires service providers to comply with different regulations, e.g., data privacy regulations others that apply financial services. For supporting interoperability, organizations can connect each via gateway. these gateways should be resilient crashes maintain consistent state across ledgers. To realize this vision, we propose Hermes, fault-tolerant middleware connects networks is based on Open Digital Asset Protocol (ODAP). Hermes crash allying protocol, ODAP-2PC, log storage API leverage secure logs, transparency, auditability, availability, non-repudiation. We briefly explore use case for cross-jurisdiction asset transfers, illustrating how one support cross-chain transactions compliant legal regulatory frameworks.
