Quorum Broadcast

Disseminate data through quorum-broadcast. The mempool waits for 2f+1 ack before forwarding the hash of the batch to the consensus layer (this acts as a control system).

Benchmark 2-chain

• Add measurements for 2-chain

Various Improvements

• Better mass client (for benchmarks)
• Clearer log aggregation tools
• Improve precision in latency measurements
• Fix bug preventing some blocks from being committed under faults

Isolate payload maker

• Performance improvements by running the payload maker in its own task.
• Minor improvement.
• Minor bug fix in the benchmarking scripts.

Optimistic Sync

• Mempool optimistically tries to sync with sender of the block. If this fails, it broadcast its sync request.
• Remove async traits to connect the mempool and consensus in a simpler way
• Better timers implementations (without using a dedicated tokio task)
• Minor bug fix on the bench scripts

2-Chain HotStuff

• Vanilla implementation of 2-chain HotStuff
• Automated plot scripts

Working WAN deployment

• Vanilla 3-chain HotStuff
• Simple mempool implementation
• Scripts for local benchmark
• Scripts for remote benchmark on AWS
