ChainConfig defines the Ethereum ChainConfig parameters using sdk.Int values instead of big.Int.

NOTE 1: Since empty/uninitialized Ints (i.e with a nil big.Int value) are parsed to zero, we need to manually specify that negative Int values will be considered as nil. See getBlockValue for reference.

NOTE 2: This type is not a configurable Param since the SDK does not allow for validation against a previous stored parameter values or the current block height (retrieved from context). If you want to update the config values, use an software upgrade procedure.

func DefaultChainConfig

DefaultChainConfig returns default evm parameters. Th

func (ChainConfig) EthereumConfig

type CommitStateDB 

type CommitStateDB struct {
	// contains filtered or unexported fields
}

CommitStateDB implements the Geth state.StateDB interface. Instead of using a trie and database for querying and persistence, the Keeper uses KVStores and an account mapper is used to facilitate state transitions.

TODO: This implementation is subject to change in regards to its statefull manner. In otherwords, how this relates to the keeper in this module.

func CreateEmptyCommitStateDB 

func CreateEmptyCommitStateDB(csdbParams CommitStateDBParams, ctx sdk.Context) *CommitStateDB

func NewCommitStateDB 

func NewCommitStateDB(csdbParams CommitStateDBParams) *CommitStateDB

NewCommitStateDB returns a reference to a newly initialized CommitStateDB which implements Geth's state.StateDB interface.

CONTRACT: Stores used for state must be cache-wrapped as the ordering of the key/value space matters in determining the merkle root.

AddAddressToAccessList adds the given address to the access list

func (*CommitStateDB) AddBalance

func (*CommitStateDB) Commit 

func (csdb *CommitStateDB) Commit(deleteEmptyObjects bool) (ethcmn.Hash, error)

Commit writes the state to the appropriate KVStores. For each state object in the cache, it will either be removed, or have it's code set and/or it's state (storage) updated. In addition, the state object (account) itself will be written. Finally, the root hash (version) will be returned.

func (*CommitStateDB) CommitMpt 

func (csdb *CommitStateDB) CommitMpt(prefetcher *mpt.TriePrefetcher) (ethcmn.Hash, error)

func (*CommitStateDB) CreateAccount 

func (csdb *CommitStateDB) CreateAccount(addr ethcmn.Address)

CreateAccount explicitly creates a state object. If a state object with the address already exists the balance is carried over to the new account.

CreateAccount is called during the EVM CREATE operation. The situation might arise that a contract does the following:

  1. sends funds to sha(account ++ (nonce + 1))
  2. tx_create(sha(account ++ nonce)) (note that this gets the address of 1)
