5 July 2026. We have been very busy! Exciting news about SATP, Hyperledger Cacti, and our research on blockchain interoperability are about to come out. Stay tuned for more updates!
2025
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.
22 April 2025. Our paper "Looking for Anomalies in Cross-Chain Bridges" has been accepted for presentation at DSN 2025.
8 March 2025. Our tutorial "Blockchain Interoperability: Theory And Practice" has been accepted for presentation at IEEE ICBC 2025.
12 February 2025. Our 28 academic papers and technical reports accumulated 1300+ citations and more than 75,000 downloads and views, over the last three years. A quick digest is available here.
1 February 2025. Our paper "Gateways for Institutional-Grade Commerce and Interoperability of Digital Assets" has been published at arXiv as a preprint.
9 January 2025. Submissions to our DepWeb3 Workshop will be accepted until 17 January.
25 October 2024. I'm very honoured to have been awarded "Best INESC-ID Ph.D. student" due to my contributions to the theory and practice of blockchain interoperability.
2 October 2024. Thrilled that our article, A Brief History of Blockchain Interoperability, is featured on the cover of the October issue of Communications of the ACM. A huge milestone for our work at BIG Era Chair!
11 November 2023. I will be out of office for several weeks, backpacking in Southeast Asia. See you in 2024!
10 November 2023. The draft for our paper SoK: Security and Privacy of Blockchain Interoperability (extended version) is almost ready to be published. Stay tuned! EDIT: published in TechRxiv.
