13 November 2025. A while ago, we created interoperability-theory, a Hyperledger Cacti repository where we aggregate research regarding blockchain interoperability. Check it out here. Our group has provided 30+ contributions in around 5 years!
12 November 2025. The release of cacti-demos version 0.0.1 was announced in today's workshop. This is a new Hyperledger Cacti repository dedicated to assisting practitioners in deploying Cacti packages, with a focus on the SATP Hermes product. Check it out here.
12 November 2025. My dear colleagues presented the workshop "Cross-Network Interoperability with Hyperledger Cacti" on interoperability. Watch it here.
20 September 2025. Our paper "Automatic Cross-chain Protocol Pausing with Real-time Conformance Checking" (related thesis) was accepted in BRAINS 2025.
6 September 2025. Our paper "XChainWatcher: Identifying Anomalies in Cross-Chain Bridges" (arXiv preprint) was accepted in Middleware 2025.
3 June 2025. Our tutorial "Blockchain Interoperability: Theory And Practice" was successfully presented at IEEE ICBC 2025. The tutorial included a practical demonstration of the SATP Gateway implementation for secure asset transfers across different blockchains.
