Struct InitStateCommand

pub struct InitStateCommand<C: ChainSpecParser> {
    pub env: EnvironmentArgs<C>,
    pub state: PathBuf,
    pub without_evm: bool,
    pub header: Option<PathBuf>,
    pub total_difficulty: Option<String>,
    pub header_hash: Option<String>,
}

Initializes the database with the genesis block.

Fields

env: EnvironmentArgs<C>

state: PathBuf

JSONL file with state dump.

Must contain accounts in following format, additional account fields are ignored. Must also contain { “root”: <state-root> } as first line. { “balance”: “<balance>”, “nonce”: <nonce>, “code”: “<bytecode>”, “storage”: { “<key>”: “<value>”, .. }, “address”: “<address>”, }

Allows init at a non-genesis block. Caution! Blocks must be manually imported up until and including the non-genesis block to init chain at. See ‘import’ command.

without_evm: bool

Specifies whether to initialize the state without relying on EVM historical data.

When enabled, and before inserting the state, it creates a dummy chain up to the last EVM block specified. It then, appends the first block provided block.

• Note: Do not import receipts and blocks beforehand, or this will fail or be ignored.

header: Option<PathBuf>

Header file containing the header in an RLP encoded format.

total_difficulty: Option<String>

Total difficulty of the header.

header_hash: Option<String>

Hash of the header.
