High Frequency Long Term Transactions in Distributed Ledgers
Network Coding Distributed Ledger
As part of a larger research project on the implementation of secure decentralized computing infrastructures, we focus on the use of Network Coding (NC) to minimize the transaction overhead in Distributed Ledgers (DL) (i.e., permissioned blockchains).
The scope of the project includes analyzing the current state of the art in both error correcting codes (ECC) and DL consensus mechanisms to identify the underlying infrastructures, challenges, and possible solutions. The proposed research also paves the way for securing DL against the threats of weak cryptography and enables higher transaction rates in consensus procedures.
The research and development carried out in this project consists of five main tasks. These tasks are:
- Development of an NC-based framework for a permissioned DL using ECC.
- Investigation of the efficiency of Random Linear NC (RLNC) for different network topologies.
- Comparison between Store-and-Forward (SF) and RLNC.
- Investigation of the various consensus mechanisms and their impact on the performance and security of the system.
- Implementation of a prototype on suitable hardware platforms and execution of performance benchmarks.
