Functions ¶
Types ¶
type API ¶
type API struct {
// contains filtered or unexported fields
}
API is a user facing RPC API to allow controlling the delegate and voting mechanisms of the delegated-proof-of-stake
func (*API) GetConfirmedBlockNumber ¶
GetConfirmedBlockNumber retrieves the latest irreversible block
func (*API) GetWitnesses ¶
func (api *API) GetWitnesses(number *rpc.BlockNumber) ([]string, error)
GetWitnesses retrieves the list of the Witnesses at specified block
type Controller ¶
type Controller struct {
TimeStamp uint64
// contains filtered or unexported fields
}
func Newcontroller ¶
func Newcontroller(devoteDB *devotedb.DevoteDB) *Controller
type Devote ¶
type Devote struct {
// contains filtered or unexported fields
}
func (*Devote) APIs ¶
func (d *Devote) APIs(chain consensus.ChainReader) []rpc.API
APIs implements consensus.Engine, returning the user facing RPC APIs.
func (*Devote) Author ¶
Author implements consensus.Engine, returning the header's coinbase as the proof-of-stake verified author of the block.
func (*Devote) CalcDifficulty ¶
func (*Devote) CheckWitness ¶
func (*Devote) Close ¶
Close implements consensus.Engine. It's a noop for Devote as there is are no background threads.
func (*Devote) Finalize ¶
func (d *Devote) Finalize(chain consensus.ChainReader, header *types.Header, state *state.StateDB, txs []*types.Transaction, uncles []*types.Header, receipts []*types.Receipt, devoteDB *devotedb.DevoteDB) (*types.Block, error)
Finalize implements consensus.Engine, accumulating the block and uncle rewards, setting the final state and assembling the block.
func (*Devote) GetGovernanceContractAddress ¶
func (d *Devote) GetGovernanceContractAddress(goveAddress GetGovernanceContractAddress)
func (*Devote) Masternodes ¶
func (d *Devote) Masternodes(masternodeListFn MasternodeListFn)
func (*Devote) Prepare ¶
Prepare implements consensus.Engine, preparing all the consensus fields of the header for running the transactions on top.
func (*Devote) Seal ¶
func (d *Devote) Seal(chain consensus.ChainReader, block *types.Block, stop <-chan struct{}) (*types.Block, error)
Seal generates a new block for the given input block with the local miner's seal place on top.
func (*Devote) VerifyHeader ¶
verifyHeader checks whether a header conforms to the consensus rules of the stock Etherzero devote engine.
func (*Devote) VerifyHeaders ¶
func (*Devote) VerifySeal ¶
VerifySeal implements consensus.Engine, checking whether the signature contained in the header satisfies the consensus protocol requirements.
func (*Devote) VerifyUncles ¶
VerifyUncles implements consensus.Engine, always returning an error for any uncles as this consensus mechanism doesn't permit uncles.
