Risks and Challenges
- Interface the Byzantine-tolerant replication and Fault-tolerant replication components.
- Investigate the impact of threshold digital signatures on performance and complexity.
- Interface Byzantine-tolerant replication with the client accountability graph.
- Use of application semantics to optimize protocols.
- Design optimizations to make the cost of the architecture very small when no faults occur.
- Take into account confidentiality under corrupted servers model.
