## EVM state transition tool
# EVM tool
The EVM tool provides a few useful subcommands to facilitate testing at the EVM
layer.
* transition tool (`t8n`) : a stateless state transition utility
* transaction tool (`t9n`) : a transaction validation utility
* block builder tool (`b11r`): a block assembler utility
## State transition tool (`t8n`)
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)
- 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
- State root, transaction root, receipt root,
- Information about rejected transactions,
- Optionally: a full or partial post-state dump
## Specification
### 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
state generators can swap between a \`geth\`-based implementation and a \`parityvm\`-based
implementation.
### Command line params
#### 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
--trace.noreturndata Disable return data output in traces
--output.basedir value Specifies where output files are placed. Will be created if it does not exist.
--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
--output.body value If set, the RLP of the transactions (block body) will be written to this file.
--input.txs stdin stdin or file name of where to find the transactions to apply. If the file prefix is '.rlp', then the data is interpreted as an RLP list of signed transactions.The '.rlp' format is identical to the output.body format. (default: "txs.json")
--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)
Command line params that need to be supported are
```
--input.alloc value (default: "alloc.json")
--input.env value (default: "env.json")
--input.txs value (default: "txs.json")

--trace.memory (default: false)
--trace.nomemory (default: true)
--trace.noreturndata (default: true)
--trace.nostack (default: false)
--trace.returndata (default: false)
```
#### Objects
### Error codes and output
The transition tool uses JSON objects to read and write data related to the transition operation. The
following object definitions are required.
##### `alloc`
The `alloc` object defines the prestate that transition will begin with.
```go
// Map of address to account definition.
type Alloc map[common.Address]Account
// Genesis account. Each field is optional.
type Account struct {
Code []byte `json:"code"`
Storage map[common.Hash]common.Hash `json:"storage"`
Balance *big.Int `json:"balance"`
Nonce uint64 `json:"nonce"`
SecretKey []byte `json:"secretKey"`
}
```
##### `env`
The `env` object defines the environmental context in which the transition will
take place.
```go
type Env struct {

#### Forks
### Basic usage
The chain configuration to be used for a transition is specified via the
`--state.fork` CLI flag. A list of possible values and configurations can be
found in [`tests/init.go`](tests/init.go).

## About Ommers
#### 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`
- (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:
To make `t8n` apply these, the following inputs are required:
- `state.reward`
- `--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`.
- For each ommer, the tool needs to be given an `addres\` and a `delta`. This
is done via the `ommers` field in `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

#### 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:
Example, putting EIP-1344 into Frontier:

```
### Block history
#### 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:

What happened here, is that we first applied two identical transactions, so the second one was rejected.
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.

## Specification
### 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.

following object definitions are required.

## About Ommers
#### 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\`
- `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:
To make `t8n` apply these, the following inputs are required:

- For each ommer, the tool needs to be given an `addres\` and a `delta`. This
