The maturing of blockchain technology leads to heterogeneity, where multiple solutions specialize in a particular use case. While the development different networks shows great potential for blockchains, isolated have led data and asset silos, limiting applications this technology. Blockchain interoperability are essential enable distributed ledgers reach their full potential. Such allow blockchains support transfer, resulting innovative applications. This paper proposes novel solution permissioned based on publish/subscribe architecture. We implemented prototype platform show feasibility our design. evaluate by implementing examples publisher subscriber networks, such as Hyperledger Besu, which is an Ethereum client, two versions Fabric. present performance analysis whole network that indicates its limits bottlenecks. Finally, we discuss extensibility scalability scenarios. Our evaluation system can handle throughput order hundreds transactions per second.
