Functions

func AdaptHash 

func AdaptHash(ethHash common.Hash) yu_common.Hash

func ConvertBigIntToUint256 

func ConvertBigIntToUint256(b *big.Int) *uint256.Int

func ConvertHashToYuHash 

func ConvertHashToYuHash(hash common.Hash) (yu_common.Hash, error)

func LoadChainConfig 

func LoadChainConfig(db ethdb.Database, genesis *Genesis) (*params.ChainConfig, error)

LoadChainConfig loads the stored chain config if it is already present in database, otherwise, return the config in the provided genesis specification.

func ObjToJson 

func ObjToJson(obj interface{}) string

func SetupGenesisBlock 

func SetupGenesisBlock(ethState *EthState, genesis *Genesis) (*params.ChainConfig, common.Hash, error)

SetupGenesisBlock writes or updates the genesis block in db. The block that will be used is: 

                     genesis == nil       genesis != nil
                  +------------------------------------------
db has no genesis |  main-net default  |  genesis
db has genesis    |  from DB           |  genesis (if compatible)

The stored chain configuration will be updated if it is compatible (i.e. does not specify a fork block below the local head block). In case of a conflict, the error is a *params.ConfigCompatError and the new, unwritten config is returned.

The returned chain configuration is never nil.

func SetupGenesisBlockWithOverride
