## EVM state transition tool
|
|
|
|
The `t8n` tool is a stateless state transition utility.
|
|
|
|
### Build instructions
|
|
|
|
There are few options to build `t8n` tool like any other nimbus tools.
|
|
|
|
1. Use nimble to install dependencies and your system Nim compiler(version <= 1.6.0).
|
|
```
|
|
$> nimble install -y --depsOnly
|
|
$> nim c -d:release -d:chronicles_default_output_device=stderr tools/t8n/t8n
|
|
$> nim c -r -d:release tools/t8n/t8n_test
|
|
```
|
|
2. Use nimbus shipped Nim compiler and dependencies.
|
|
```
|
|
$> make update deps
|
|
$> ./env.sh nim c -d:release -d:chronicles_default_output_device=stderr tools/t8n/t8n
|
|
$> ./env.sh nim c -r -d:release tools/t8n/t8n_test
|
|
```
|
|
3. Use nimbus makefile.
|
|
```
|
|
$> make update
|
|
$> make t8n
|
|
$> make t8n_test
|
|
```
|
|
|
|

Usage:
|
|
|
|
t8n [OPTIONS]...
|
|
|
|
The following options are available:
|
|
|
|
--trace Output full trace logs to files trace-<txIndex>-<txhash>.jsonl [=false].
|
|
--trace.memory Enable full memory dump in traces [=false].
|
|
--trace.nostack Disable stack output in traces [=false].
|
|
--trace.returndata Enable return data output in traces [=false].
|
|
--output.basedir Specifies where output files are placed. Will be created if it does not exist.
|
|
--output.body If set, the RLP of the transactions (block body) will be written to this file.
|
|
--output.alloc Determines where to put the `alloc` of the post-state. [=alloc.json].
|
|
`stdout` - into the stdout output.
|
|
`stderr` - into the stderr output.
|
|
<file> - into the file <file>.
|
|
--output.result Determines where to put the `result` (stateroot, txroot etc) of the post-state.
|
|
[=result.json].
|
|
`stdout` - into the stdout output.
|
|
`stderr` - into the stderr output.
|
|
<file> - into the file <file>.
|
|
--input.alloc `stdin` or file name of where to find the prestate alloc to use. [=alloc.json].
|
|
--input.env `stdin` or file name of where to find the prestate env to use. [=env.json].
|
|
--input.txs `stdin` or file name of where to find the transactions to apply. If the file
|
|
extension is '.rlp', then the data is interpreted as an RLP list of signed
|
|
transactions. The '.rlp' format is identical to the output.body format.
|
|
[=txs.json].
|
|
--state.reward Mining reward. Set to -1 to disable [=0].
|
|
--state.chainid ChainID to use [=1].
|
|
--state.fork Name of ruleset to use. [=GrayGlacier].
