func Random ¶

func Random(header *types.Header, state vm.StateDB) (common.Hash, error)

Random performs an internal call to the EVM to retrieve the current randomness from the official Random contract.

func RevealAndCommit ¶

func RevealAndCommit(randomness, newCommitment common.Hash, proposer common.Address, header *types.Header, state vm.StateDB) error

RevealAndCommit performs an internal call to the EVM that reveals a proposer's previously committed to randomness, and commits new randomness for a future block.
