## EVM state transition tool
|
||||
|
||||
The `evm t8n` tool is a stateless state transition utility. It is a utility
|
||||
which can
|
||||
|
||||
1. Take a prestate, including
|
||||
- Accounts,
|
||||
- Block context information,
|
||||
- Previous blockshashes (*optional)
|
||||
2. Apply a set of transactions,
|
||||
3. Apply a mining-reward (*optional),
|
||||
4. And generate a post-state, including
|
||||
- State root, transaction root, receipt root,
|
||||
- Information about rejected transactions,
|
||||
- Optionally: a full or partial post-state dump
|
||||
|
||||
## Specification
|
||||
|
||||
The idea is to specify the behaviour of this binary very _strict_, so that other
|
||||
node implementors can build replicas based on their own state-machines, and the
|
||||
state generators can swap between a `geth`-based implementation and a `parityvm`-based
|
||||
implementation.
|
||||
|
||||
### Command line params
|
||||
|
||||
Command line params that has to be supported are
|
||||
```
|
||||
|
||||
--trace Output full trace logs to files <txhash>.jsonl
|
||||
--trace.nomemory Disable full memory dump in traces
|
||||
--trace.nostack Disable stack output in traces
|
||||
--output.alloc alloc Determines where to put the alloc of the post-state.
|
||||
`stdout` - into the stdout output
|
||||
`stderr` - into the stderr output
|
||||
--output.result result Determines where to put the result (stateroot, txroot etc) of the post-state.
|
||||
`stdout` - into the stdout output
|
||||
`stderr` - into the stderr output
|
||||
--state.fork value Name of ruleset to use.
|
||||
--state.chainid value ChainID to use (default: 1)
|
||||
--state.reward value Mining reward. Set to -1 to disable (default: 0)
|
||||
|
||||
```
|
||||
|
||||
### Error codes and output
|
||||
|
||||
All logging should happen against the `stderr`.
|
||||
There are a few (not many) errors that can occur, those are defined below.
|
||||
|
||||
#### EVM-based errors (`2` to `9`)
|
||||
|
||||
- Other EVM error. Exit code `2`
|
||||
- Failed configuration: when a non-supported or invalid fork was specified. Exit code `3`.
|
||||
- Block history is not supplied, but needed for a `BLOCKHASH` operation. If `BLOCKHASH`
|
||||
is invoked targeting a block which history has not been provided for, the program will
|
||||
exit with code `4`.
|
||||
|
||||
#### IO errors (`10`-`20`)
|
||||
|
||||
- Invalid input json: the supplied data could not be marshalled.
|
||||
The program will exit with code `10`
|
||||
- IO problems: failure to load or save files, the program will exit with code `11`
|
||||
|
||||
## Examples
|
||||
### Basic usage
|
||||
|
||||
Invoking it with the provided example files
|
||||
```
|
||||
./evm t8n --input.alloc=./testdata/1/alloc.json --input.txs=./testdata/1/txs.json --input.env=./testdata/1/env.json
|
||||
```
|
||||
Two resulting files:
|
||||
|
||||
`alloc.json`:
|
||||
```json
|
||||
{
|
||||
"0x8a8eafb1cf62bfbeb1741769dae1a9dd47996192": {
|
||||
"balance": "0xfeed1a9d",
|
||||
"nonce": "0x1"
|
||||
},

|
||||

|
||||
}
|
||||
}
|
||||
```
|
||||

|
||||
|
||||
We can make them spit out the data to e.g. `stdout` like this:
|
||||
```
|
||||
./evm t8n --input.alloc=./testdata/1/alloc.json --input.txs=./testdata/1/txs.json --input.env=./testdata/1/env.json --output.result=stdout --output.alloc=stdout
|
||||
```
|
||||
Output:
|
||||
```json
|
||||

|
||||

## About Ommers
|
||||
|
||||
Mining rewards and ommer rewards might need to be added. This is how those are applied:
|
||||
|
||||
- `block_reward` is the block mining reward for the miner (`0xaa`), of a block at height `N`.
|
||||
- For each ommer (mined by `0xbb`), with blocknumber `N-delta`
|
||||
- (where `delta` is the difference between the current block and the ommer)
|
||||
- The account `0xbb` (ommer miner) is awarded `(8-delta)/ 8 * block_reward`
|
||||
- The account `0xaa` (block miner) is awarded `block_reward / 32`
|
||||
|
||||
To make `state_t8n` apply these, the following inputs are required:
|
||||
|
||||
- `state.reward`
|
||||
- For ethash, it is `5000000000000000000` `wei`,
|
||||
- If this is not defined, mining rewards are not applied,
|
||||
- A value of `0` is valid, and causes accounts to be 'touched'.
|
||||
- For each ommer, the tool needs to be given an `address` and a `delta`. This
|
||||
is done via the `env`.
|
||||
|
||||
Note: the tool does not verify that e.g. the normal uncle rules apply,
|
||||
and allows e.g two uncles at the same height, or the uncle-distance. This means that
|
||||
the tool allows for negative uncle reward (distance > 8)
|
||||
|
||||
Example:
|
||||
`./testdata/5/env.json`:
|
||||
```json
|
||||
{
|
||||
"currentCoinbase": "0xaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa",
|
||||
"currentDifficulty": "0x20000",
|
||||
"currentGasLimit": "0x750a163df65e8a",
|
||||
"currentNumber": "1",
|
||||
"currentTimestamp": "1000",
|
||||
"ommers": [
|
||||
{"delta": 1, "address": "0xbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb" },
|
||||
{"delta": 2, "address": "0xcccccccccccccccccccccccccccccccccccccccc" }
|
||||
]
|
||||
}
|
||||
```
|
||||
When applying this, using a reward of `0x08`
|
||||
Output:
|
||||
```json
|
||||
{
|
||||
"alloc": {
|
||||
"0xaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa": {
|
||||
"balance": "0x88"
|
||||
},
|
||||
"0xbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb": {
|
||||
"balance": "0x70"
|
||||
},
|
||||
"0xcccccccccccccccccccccccccccccccccccccccc": {
|
||||
"balance": "0x60"
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
### Future EIPS
|
||||
|
||||
It is also possible to experiment with future eips that are not yet defined in a hard fork.
|
||||
Example, putting EIP-1344 into Frontier:
|
||||
```
|
||||
./evm t8n --state.fork=Frontier+1344 --input.pre=./testdata/1/pre.json --input.txs=./testdata/1/txs.json --input.env=/testdata/1/env.json
|
||||
```
|
||||
|
||||
### Block history
|
||||
|
||||
The `BLOCKHASH` opcode requires blockhashes to be provided by the caller, inside the `env`.
|
||||
If a required blockhash is not provided, the exit code should be `4`:
|
||||
Example where blockhashes are provided:
|
||||
```
|
||||
./evm t8n --input.alloc=./testdata/3/alloc.json --input.txs=./testdata/3/txs.json --input.env=./testdata/3/env.json --trace
|
||||
```
|
||||
```
|
||||
cat trace-0.jsonl | grep BLOCKHASH -C2
|
||||
```
|
||||
```
|
||||
{"pc":0,"op":96,"gas":"0x5f58ef8","gasCost":"0x3","memory":"0x","memSize":0,"stack":[],"returnStack":[],"depth":1,"refund":0,"opName":"PUSH1","error":""}
|
||||
{"pc":2,"op":64,"gas":"0x5f58ef5","gasCost":"0x14","memory":"0x","memSize":0,"stack":["0x1"],"returnStack":[],"depth":1,"refund":0,"opName":"BLOCKHASH","error":""}
|
||||
{"pc":3,"op":0,"gas":"0x5f58ee1","gasCost":"0x0","memory":"0x","memSize":0,"stack":["0xdac58aa524e50956d0c0bae7f3f8bb9d35381365d07804dd5b48a5a297c06af4"],"returnStack":[],"depth":1,"refund":0,"opName":"STOP","error":""}
|
||||
{"output":"","gasUsed":"0x17","time":155861}
|
||||
```
|
||||
|
||||
In this example, the caller has not provided the required blockhash:
|
||||
```
|
||||
./evm t8n --input.alloc=./testdata/4/alloc.json --input.txs=./testdata/4/txs.json --input.env=./testdata/4/env.json --trace
|
||||
```
|
||||
```
|
||||
ERROR(4): getHash(3) invoked, blockhash for that block not provided
|
||||
```
|
||||
Error code: 4
|
||||
### Chaining
|
||||
|
||||
Another thing that can be done, is to chain invocations:
|
||||
```
|
||||
./evm t8n --input.alloc=./testdata/1/alloc.json --input.txs=./testdata/1/txs.json --input.env=./testdata/1/env.json --output.alloc=stdout | ./evm t8n --input.alloc=stdin --input.env=./testdata/1/env.json --input.txs=./testdata/1/txs.json
|
||||
INFO [06-29|11:52:04.934] rejected tx index=1 hash="0557ba…18d673" from=0x8A8eAFb1cf62BfBeb1741769DAE1a9dd47996192 error="nonce too low"
|
||||
INFO [06-29|11:52:04.936] rejected tx index=0 hash="0557ba…18d673" from=0x8A8eAFb1cf62BfBeb1741769DAE1a9dd47996192 error="nonce too low"
|
||||
INFO [06-29|11:52:04.936] rejected tx index=1 hash="0557ba…18d673" from=0x8A8eAFb1cf62BfBeb1741769DAE1a9dd47996192 error="nonce too low"
|
||||
|
||||
```
|
||||
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.
|
||||

## EVM state transition tool
|
||||
|
||||
The \`evm t8n\` tool is a stateless state transition utility. It is a utility
|
||||
which can
|
||||
|
||||
1. Take a prestate, including
|
||||
- Accounts,
|
||||
- Block context information,
|
||||
- Previous blockshashes (*optional)
|
||||
2. Apply a set of transactions,
|
||||
3. Apply a mining-reward (*optional),
|
||||
4. And generate a post-state, including
|
||||
- State root, transaction root, receipt root,
|
||||
- Information about rejected transactions,
|
||||
- Optionally: a full or partial post-state dump
|
||||
|
||||
## Specification
|
||||
|
||||
The idea is to specify the behaviour of this binary very _strict_, so that other
|
||||
node implementors can build replicas based on their own state-machines, and the
|
||||
state generators can swap between a \`geth\`-based implementation and a \`parityvm\`-based
|
||||
implementation.
|
||||
|
||||
### Command line params
|
||||
|
||||
Command line params that has to be supported are
|
||||
$(tick)
|
||||
|
||||
` ./evm t8n -h | grep "trace\|output\|state\."`
|
||||
|
||||
$(tick)
|
||||
|
||||
### Error codes and output
|
||||
|
||||
All logging should happen against the \`stderr\`.
|
||||
There are a few (not many) errors that can occur, those are defined below.
|
||||
|
||||
#### EVM-based errors (\`2\` to \`9\`)
|
||||
|
||||
- Other EVM error. Exit code \`2\`
|
||||
- Failed configuration: when a non-supported or invalid fork was specified. Exit code \`3\`.
|
||||
- Block history is not supplied, but needed for a \`BLOCKHASH\` operation. If \`BLOCKHASH\`
|
||||
is invoked targeting a block which history has not been provided for, the program will
|
||||
exit with code \`4\`.
|
||||
|
||||
#### IO errors (\`10\`-\`20\`)
|
||||
|
||||
- Invalid input json: the supplied data could not be marshalled.
|
||||
The program will exit with code \`10\`
|
||||
- IO problems: failure to load or save files, the program will exit with code \`11\`
|
||||
|
||||
EOF
|
||||
|
||||
# This should exit with 3

## About Ommers
|
||||
|
||||
Mining rewards and ommer rewards might need to be added. This is how those are applied:
|
||||
|
||||
- \`block_reward\` is the block mining reward for the miner (\`0xaa\`), of a block at height \`N\`.
|
||||
- For each ommer (mined by \`0xbb\`), with blocknumber \`N-delta\`
|
||||
- (where \`delta\` is the difference between the current block and the ommer)
|
||||
- The account \`0xbb\` (ommer miner) is awarded \`(8-delta)/ 8 * block_reward\`
|
||||
- The account \`0xaa\` (block miner) is awarded \`block_reward / 32\`
|
||||
|
||||
To make \`state_t8n\` apply these, the following inputs are required:
|
||||
|
||||
- \`state.reward\`
|
||||
- For ethash, it is \`5000000000000000000\` \`wei\`,
|
||||
- If this is not defined, mining rewards are not applied,
|
||||
- A value of \`0\` is valid, and causes accounts to be 'touched'.
|
||||
- For each ommer, the tool needs to be given an \`address\` and a \`delta\`. This
|
||||
is done via the \`env\`.
|
||||
|
||||
Note: the tool does not verify that e.g. the normal uncle rules apply,
|
||||
and allows e.g two uncles at the same height, or the uncle-distance. This means that
|
||||
the tool allows for negative uncle reward (distance > 8)
|
||||
|
||||

|
||||

||||

||||
