The init command initializes a new genesis block and definition for the network.
Supports SubnetEVM genesis format with proper field handling.`,

		Flags: []cli.Flag{
			utils.DataDirFlag,
			namespaceFlag,

		Description: `
Export blocks from a SubnetEVM pebbledb database to an RLP-encoded file.

		Flags:     utils.DatabaseFlags,
		Description: `
Performs disaster recovery by:
1. Initializing with computed genesis (produces NEW genesis hash)
2. Extracting transactions from old blocks
3. Replaying transactions to rebuild state

NOTE: Block hashes will differ from original chain.
Transaction history and final state are preserved.`,
