-# Fullnode
-
-This document proposes the following architecture changes to fullnode pipeline.
-
-## Current Architecture
-
-
-## Proposal
-
-
-## Background
-
-In the old architecture, the ReplayStage receives entries from the RetransmitStage,
-processes them and writes to the ledger.
-
-In the current code, the ledger write operation has been moved out of the ReplayStage.
-If the fullnode is running with a TPU, the Broadcast Service writes to the ledger.
-The Retransmit Stage receives entries from peer fullnodes and also writes to the ledger.
-
-The ledger notifies the ReplayStage whenever some entity writes to it. The
-ReplayStage reads from the ledger, processes the entries in the bank and submits
-the votes.
-
-In old architecture, the RetransmitStage and ReplayStage are contained in the TVU.
-
-## Changes
-
-This document proposes the following change to the architecture.
-
-1. Split TVU into BlobFetchStage, and ReplayStage
-2. Add Blocktree (ledger) to the diagram
-3. The Blocktree is updated by Broadcast Service and BlobFetchStage
-4. Replay Stage gets notified by Blocktree when someone writes to it
-5. Replay Stage submits votes via Gossip Service
-6. Replace Bank with BankForks
