+
+**Note:**
+
+1. Validium doesn’t include blob KZG verification, which adds some overhead.
+2. Validium doesn’t publishes blobs, which can limit batch size.
+3. The L2 state is small. A bigger state means a bigger trie, which implies more trie/hashing operations that increase proving time.
+4. For the big state case, the accounts don’t have storage nor code.
+
+### How to reproduce
+
+1. Install [SP1 toolchain](https://docs.succinct.xyz/docs/sp1/getting-started/install#option-1-prebuilt-binaries-recommended)
+2. Checkout the `l2/tps` ethrex branch
+    1. in there I modified load tests to add a tps test
+    2. and I modified the prover log level from **debug** to **info**
+3. cd `crates/l2`, build and init the prover: 
+    1. `make build-prover PROVER=sp1 G=1` 
+    2. `make init-prover PROVER=sp1 G=1`
+4. In a different terminal (cd `crates/l2`) init L1 and L2:
+    1. for this execute `make init` setting env. vars according to the L2 setup:
+        1. `ETHREX_DEPLOYER_SP1_DEPLOYER_VERIFIER=true`
+        2. `ETHREX_NO_MONITOR=true`
+        3. `ETHREX_L2_VALIDIUM=<true,false>`
+        4. `ETHREX_BLOCK_PRODUCER_BLOCK_TIME=12000`
+        5. `ETHREX_COMMITTER_COMMIT_TIME=768000`
+5. In a different terminal (cd `tooling/load_test/` ) execute the TPS test
+    ```rust
+    cargo r -r -- load \
+	--node http://127.0.0.1:1729 \
+	--pkeys ../../fixtures/keys/private_keys.txt \
+	--test-type <eth-transfers,erc20> \
+	tps \
+	--rate <tx per second>
+    ```
