Functions

func ReadChainConfig

func ReadChainConfig(db ethdb.KeyValueReader, hash common.Hash) *params.ChainConfig

ReadChainConfig retrieves the consensus settings based on the given genesis hash.

func ReadHeadHeader

func ReadHeadHeader(db ethdb.Reader) *mivetypes.Header

ReadHeadHeader returns the current canonical head header.

func ReadHeader

func ReadHeader(db ethdb.Reader, hash common.Hash, number uint64) *mivetypes.Header

ReadHeader retrieves the block header corresponding to the hash.

func WriteChainConfig

func WriteChainConfig(db ethdb.KeyValueWriter, hash common.Hash, cfg *params.ChainConfig)

WriteChainConfig writes the chain config settings to the database.

func WriteHeader

func WriteHeader(db ethdb.KeyValueWriter, header *mivetypes.Header)

WriteHeader stores a block header into the database and also stores the hash- to-number mapping.
