Key Points:

‍

1. Co-authorship – The paper on sharding in Hedera is co-written by Ziwei Wang, Cong Wu, and Paolo Tasca, affiliated with Exponential Science.
2. Goal – Explore how sharding can boost Hedera’s scalability (higher throughput, lower latency) without losing decentralization.
3. Proposal – A hybrid sharding model with local committees (handling shard transactions) and a global committee (coordinating cross-shard activity).
4. Security & efficiency – Random node assignment, dynamic reconfiguration, and redundancy ensure Byzantine Fault Tolerance while reducing overhead.
5. Contribution of Paolo – He helps shape the conceptual framework and positions the work within the broader blockchain/DLT research landscape.
