+
+## Write Path: Transaction Submission
+
+1. Users connect to the Geth rollup using standard Ethereum tooling such as
+   Metamask or Foundry and sign and submit transactions which land in the
+   rollup’s mempool.
+
+2. The Composer retrieves pending transactions from the rollup’s mempool in the
+   order in which they were received (ie. first come, first serve), wraps them
+   in an Astria transaction, and submits them to Astria’s CometBFT mempool. In
+   the current architecture, an instance of the Composer is run alongside each
+   individual rollup.
+
+    Our hope is that the Composer serves as a starting point for searchers and block
+    builders interested in collecting end user order flow for one or more rollups
+    and submitting it to the shared sequencer as bundles or blocks.
+
+3. The Astria Shared Sequencer Network creates a single “meta block” consisting
+   of transactions submitted to its mempool by one or more rollups.
+
+    The development cluster relies on a single Astria sequencer node. In a live
+    network, a decentralized set of nodes would use CometBFT to reach consensus.
+    Note that Astria is a lazy sequencer, it provides a guarantee on the
+    ordering of transactions in a block, but it doesn’t execute the state
+    transition function (STF) of any given rollup.
+
+4. The ordered blocks from the sequencer are retrieved by the Relayer, which
+   sends them to both the Conductor and the data availability layer, Celestia.
+
+    In the default development cluster configuration, Astria’s block time is
+    ~1-second, while Celestia’s is ~11-seconds. At each Astria block time, blocks
+    are sent to the Conductor and added to a queue of pending blocks waiting to be
+    written to Celestia. At each Celestia block time these pending blocks are
+    aggregated into a single batch which is submitted as one transaction to
+    Celestia.
+
+    A batch of sequencer blocks are included as a transactions in a Celestia block,
+    at this point we consider the ordering of transactions to be finalized.
+
+## Read Path: Block Retrieval and Execution
+
+5. Each rollup runs its own instance of the Conductor. The Conductor receives
+   individual blocks with Astria sequencer soft commitments at ~1-second Astria
+   block times, and batches of blocks with firm commitments from Celestia at
+   ~11-second Celestia block times. The Conductor filters these blocks, or
+   batches of blocks, to contain only the data for its particular rollup’s
+   namespace. Filtered blocks are passed to the rollup to be executed, resulting
+   in an updated rollup state and state root.
+
+    When the Conductor receives a batch of blocks from Celestia that it has
+    previously seen from Astria, it informs the rollup that these blocks are
+    finalized.
