Various error messages to mark blocks invalid. These should be private to prevent engine specific errors from being referenced in the remainder of the codebase, inherently breaking if the engine is swapped out. Please put common error types into the consensus package.

Functions

func GetInteractiveABI 

func GetInteractiveABI() map[string]abi.ABI

func GetMESHBalanceKey 

func GetMESHBalanceKey(addr common.Address) common.Hash

Types

type API 

type API struct {
	// contains filtered or unexported fields
}

func (*API) BindInfo 

func (api *API) BindInfo(addr *common.Address, num *big.Int) (map[string]interface{}, error)

func (*API) BindSign 

func (api *API) BindSign(from *common.Address) (string, error)

func (*API) GetMiner 

func (api *API) GetMiner() (*TribeMiner, error)

func (*API) GetValidators 

func (api *API) GetValidators(number *big.Int) ([]common.Address, error)

type Snapshot 

type Snapshot struct {
	Number     uint64                      `json:"number"`     // Block number where the snapshot was created
	Hash       common.Hash                 `json:"hash"`       // Block hash where the snapshot was created
	Validators map[common.Address]struct{} `json:"validators"` // Set of authorized validators at this moment
	// contains filtered or unexported fields
}

Snapshot is the state of the random pos validators at a given epoch time.

type StateFn 

type StateFn func(hash common.Hash) (*state.StateDB, error)

StateFn gets state by the state root hash.

type Tribe 

type Tribe struct {
	// contains filtered or unexported fields
}

func New 

func New(accman *accounts.Manager, config *params.TribeConfig, db ethdb.Database) *Tribe

signers set to the ones provided by the user.

func (*Tribe) APIs 

func (t *Tribe) APIs(chain consensus.ChainReader) []rpc.API

APIs implements consensus.Engine, returning the user facing RPC API to allow controlling the signer voting.

func (*Tribe) Author 

func (t *Tribe) Author(header *types.Header) (common.Address, error)

Author implements consensus.Engine, returning the Ethereum address recovered from the signature in the header's extra-data section.

func (*Tribe) CalcDifficulty 

func (t *Tribe) CalcDifficulty(chain consensus.ChainReader, time uint64, parent *types.Header) *big.Int

CalcDifficulty is the difficulty adjustment algorithm. It returns the difficulty that a new block should have based on the previous blocks in the chain and the current signer.

func (*Tribe) Finalize 

func (t *Tribe) Finalize(chain consensus.ChainReader, header *types.Header, state *state.StateDB, txs []*types.Transaction, uncles []*types.Header, receipts []*types.Receipt) (*types.Block, error)

Finalize implements consensus.Engine, ensuring no uncles are set, nor block rewards given, and returns the final block.

func (*Tribe) GetConfig 

func (t *Tribe) GetConfig() *params.TribeConfig

func (*Tribe) GetMinerAddress 

func (self *Tribe) GetMinerAddress() common.Address

func (*Tribe) GetMinerAddressByChan 

func (self *Tribe) GetMinerAddressByChan(rtn chan common.Address)

func (*Tribe) Init 

func (t *Tribe) Init(fn StateFn, nodekey *ecdsa.PrivateKey)

func (*Tribe) Prepare 

func (t *Tribe) Prepare(chain consensus.ChainReader, header *types.Header) error

Prepare implements consensus.Engine, preparing all the consensus fields of the header for running the transactions on top.

func (*Tribe) Seal 

func (t *Tribe) Seal(chain consensus.ChainReader, block *types.Block, stop <-chan struct{}) (*types.Block, error)

Seal implements consensus.Engine, attempting to create a sealed block using the local signing credentials.

func (*Tribe) SetConfig 

func (t *Tribe) SetConfig(config *params.TribeConfig)

func (*Tribe) VerifyHeader 

func (t *Tribe) VerifyHeader(chain consensus.ChainReader, header *types.Header, seal bool) error

VerifyHeader checks whether a header conforms to the consensus rules.

func (*Tribe) VerifyHeaders 

func (t *Tribe) VerifyHeaders(chain consensus.ChainReader, headers []*types.Header, seals []bool) (chan<- struct{}, <-chan error)

VerifyHeaders is similar to VerifyHeader, but verifies a batch of headers. The method returns a quit channel to abort the operations and a results channel to retrieve the async verifications (the order is that of the input slice).

func (*Tribe) VerifySeal 

func (t *Tribe) VerifySeal(chain consensus.ChainReader, header *types.Header) error

VerifySeal implements consensus.Engine, checking whether the signature contained in the header satisfies the consensus protocol requirements. don't support remote miner agent, these code never reached

func (*Tribe) VerifyUncles 

func (t *Tribe) VerifyUncles(chain consensus.ChainReader, block *types.Block) error

VerifyUncles implements consensus.Engine, always returning an error for any uncles as this consensus mechanism doesn't permit uncles.

type TribeMiner 

type TribeMiner struct {
	Address common.Address `json:"address"`
	Balance *big.Int       `json:"balance"`
}
