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 ¶
func DefaultChainConfig() ChainConfig
DefaultChainConfig returns default evm parameters. Th
func (ChainConfig) EthereumConfig ¶

func (ChainConfig) IsIstanbul ¶
func (cc ChainConfig) IsIstanbul() bool

type CommitStateDB ¶
type CommitStateDB struct { Watcher Watcher // 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

AddPreimage records a SHA3 preimage seen by the VM.
func (*CommitStateDB) AddRefund ¶

AddRefund adds gas to the refund counter.
func (*CommitStateDB) AddSlotToAccessList ¶
func (csdb *CommitStateDB) AddSlotToAccessList(addr ethcmn.Address, slot ethcmn.Hash)

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) 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:
- sends funds to sha(account ++ (nonce + 1))
- tx_create(sha(account ++ nonce)) (note that this gets the address of 1)
Carrying over the balance ensures that Ether doesn't disappear.

Error returns the first non-nil error the StateDB encountered.
func (*CommitStateDB) Exist ¶
