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.
- Use your system Nim compiler(v1.6.12) and git to install dependencies.
$> git submodule update --init --recursive $> ./env.sh (run once to generate nimbus-build-system.paths) $> nim c -d:release -d:chronicles_default_output_device=stderr tools/t8n/t8n $> nim c -r -d:release tools/t8n/t8n_test - 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 - Use nimbus makefile.
$> make update $> make t8n $> make t8n_test
Command line params
Available command line params
Usage:
t8n [OPTIONS]...
The following options are available:
--trace Enable and set where to put full EVM trace logs [=disabled].
`stdout` - into the stdout output.
`stderr` - into the stderr output.
<file> - into the file <file>-<txIndex>.jsonl.
none - output.basedir/trace-<txIndex>-<txhash>.jsonl.
--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].
