- Fetch Stage
- Incoming blobs are picked up from the replicate socket and repair socket.
- SharedWindow Stage
- Blobs are windowed until a contiguous chunk is available. This stage also repairs and retransmits blobs that are in the queue.
- Replicate Stage
- Transactions in blobs are processed and applied to the bank.
- TODO We need to verify the signatures in the blobs.
