pbft's Issues
Testing network partition
We need to find a way to delay the network arbitrarily.
Possible solutions/hacks:
- Write multiple versions of the server that simply ignore or doesn't accept messages
- Shadow the Rpc module with our own testing module
Benchmark
Monitor server memory size to ensure garbage collection is implemented fully.
Implement checkpointing
Implement visualizer of pbft servers
For two reasons:
- Easier to debug
- More visualization
Implement view change
There're often lengthy delays between when webapp sends request and when the data is updated
Determine ideal timeout
Currently, we are doing a timeout every time a network connection fails to establish, in order to avoid doing endless retries and yield time to the cpu. The current default timeout is 0.5 second, although this isn't necessarily the most ideal. The challenge is to find a good balance between yielding enough time to the cpu while still keep on retrying network connection in short periods of time.
Conceptual: How does replica know what is the correct order of transactions? Does it base it on what it gets from preprepare, prepare, or from simply the numbering of sequence numbers?
Add message digest support
Time to bring us up to speed with security
