 This command will:
- * Start `geth` in fast sync mode (default, can be changed with the `--syncmode` flag),
+ * Start `geth` in snap sync mode (default, can be changed with the `--syncmode` flag),
   causing it to download more data in exchange for avoiding processing the entire history
   of the Ethereum network, which is very CPU intensive.
 * Start up `geth`'s built-in interactive [JavaScript console](https://geth.ethereum.org/docs/interface/javascript-console),

+What happened here, is that we first applied two identical transactions, so the second one was rejected.
 Then, taking the poststate alloc as the input for the next state, we tried again to include
 the same two transactions: this time, both failed due to too low nonce.

 In order to meaningfully chain invocations, one would need to provide meaningful new `env`, otherwise the
 actual blocknumber (exposed to the EVM) would not increase.
+
+### Transactions in RLP form
+
+It is possible to provide already-signed transactions as input to, using an `input.txs` which ends with the `rlp` suffix.
+The input format for RLP-form transactions is _identical_ to the _output_ format for block bodies. Therefore, it's fully possible
+to use the evm to go from `json` input to `rlp` input.
+
+The following command takes **json** the transactions in `./testdata/13/txs.json` and signs them. After execution, they are output to `signed_txs.rlp`.:
+```
+./evm t8n --state.fork=London --input.alloc=./testdata/13/alloc.json --input.txs=./testdata/13/txs.json --input.env=./testdata/13/env.json --output.result=alloc_jsontx.json --output.body=signed_txs.rlp

+
+```
+
+The `output.body` is the rlp-list of transactions, encoded in hex and placed in a string a'la `json` encoding rules:
+```
+cat signed_txs.rlp
+"0xf8d2b86702f864010180820fa08284d09411111111111111111111111111111111111111118080c001a0b7dfab36232379bb3d1497a4f91c1966b1f932eae3ade107bf5d723b9cb474e0a06261c359a10f2132f126d250485b90cf20f30340801244a08ef6142ab33d1904b86702f864010280820fa08284d09411111111111111111111111111111111111111118080c080a0d4ec563b6568cd42d998fc4134b36933c6568d01533b5adf08769270243c6c7fa072bf7c21eac6bbeae5143371eef26d5e279637f3bd73482b55979d76d935b1e9"
+```
+
+We can use `rlpdump` to check what the contents are:
+```
+rlpdump -hex $(cat signed_txs.rlp | jq -r )
+[
+  02f864010180820fa08284d09411111111111111111111111111111111111111118080c001a0b7dfab36232379bb3d1497a4f91c1966b1f932eae3ade107bf5d723b9cb474e0a06261c359a10f2132f126d250485b90cf20f30340801244a08ef6142ab33d1904,

+]
+```
+Now, we can now use those (or any other already signed transactions), as input, like so:
+```
+./evm t8n --state.fork=London --input.alloc=./testdata/13/alloc.json --input.txs=./signed_txs.rlp --input.env=./testdata/13/env.json --output.result=alloc_rlptx.json

+
+```
+
+You might have noticed that the results from these two invocations were stored in two separate files.
+And we can now finally check that they match.
+```
+cat alloc_jsontx.json | jq .stateRoot && cat alloc_rlptx.json | jq .stateRoot

No exec (since no code). \n\nIn geth, the result would be that `0xaa` had `6 wei`, whereas OE reported (correctly) `5` wei. Furthermore, in geth, if the second tx was not executed, the `0xaa` would be destructed, resulting in `0 wei`. Thus obviously wrong. \n\nIt was determined that the root cause was this [commit](https://github.com/ethereum/go-ethereum/commit/223b950944f494a5b4e0957fd9f92c48b09037ad) from [this PR](https://github.com/ethereum/go-ethereum/pull/19953).
