Types ¶
type API ¶
type API struct {
// contains filtered or unexported fields
}
API is a user facing RPC API to dump Istanbul state
func (*API) GetContractABI ¶ added in v0.2.1
Get Autonity contract ABI
func (*API) GetContractAddress ¶ added in v0.2.1
Get Autonity contract address
func (*API) GetValidators ¶
GetValidators retrieves the list of authorized validators at the specified block.
func (*API) GetValidatorsAtHash ¶
GetValidatorsAtHash retrieves the state snapshot at a given block.
type Backend ¶
type Backend struct {
// contains filtered or unexported fields
}
func New ¶
func New(config *istanbul.Config, privateKey *ecdsa.PrivateKey, db ethdb.Database, chainConfig *params.ChainConfig, vmConfig *vm.Config) *Backend
New creates an Ethereum Backend for Istanbul core engine.
func (*Backend) APIs ¶
func (sb *Backend) APIs(chain consensus.ChainReader) []rpc.API
APIs returns the RPC APIs this consensus engine provides.
func (*Backend) Author ¶
Author retrieves the Ethereum address of the account that minted the given block, which may be different from the header's coinbase if a consensus engine is based on signatures.
func (*Backend) Broadcast ¶
func (sb *Backend) Broadcast(valSet istanbul.ValidatorSet, payload []byte) error
Broadcast implements istanbul.Backend.Broadcast
func (*Backend) CalcDifficulty ¶
func (sb *Backend) 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 blockchain and the current signer.
func (*Backend) CheckSignature ¶
CheckSignature implements istanbul.Backend.CheckSignature
func (*Backend) Finalize ¶
func (sb *Backend) Finalize(chain consensus.ChainReader, header *types.Header, state *state.StateDB, txs []*types.Transaction, uncles []*types.Header)
Finalize runs any post-transaction state modifications (e.g. block rewards) and assembles the final block.
Note, the block header and state database might be updated to reflect any consensus rules that happen at finalization (e.g. block rewards).
func (*Backend) FinalizeAndAssemble ¶ added in v0.2.1
func (*Backend) GetProposer ¶
GetProposer implements istanbul.Backend.GetProposer
func (*Backend) Gossip ¶
func (sb *Backend) Gossip(valSet istanbul.ValidatorSet, payload []byte) error
Broadcast implements istanbul.Backend.Gossip
func (*Backend) HasPropsal ¶
HasPropsal implements istanbul.Backend.HashBlock
func (*Backend) LastProposal ¶
func (*Backend) NewChainHead ¶
func (*Backend) Prepare ¶
Prepare initializes the consensus fields of a block header according to the rules of a particular engine. The changes are executed inline.
func (*Backend) Seal ¶
func (sb *Backend) Seal(chain consensus.ChainReader, block *types.Block, results chan<- *types.Block, stop <-chan struct{}) error
Seal generates a new block for the given input block with the local miner's seal place on top.
func (*Backend) SetBroadcaster ¶
func (sb *Backend) SetBroadcaster(broadcaster consensus.Broadcaster)
SetBroadcaster implements consensus.Handler.SetBroadcaster
func (*Backend) SetProposedBlockHash ¶
func (*Backend) Start ¶
func (sb *Backend) Start(_ context.Context, chain consensus.ChainReader, currentBlock func() *types.Block, hasBadBlock func(hash common.Hash) bool) error
Start implements consensus.BFT.Start
func (*Backend) Validators ¶
func (sb *Backend) Validators(number uint64) istanbul.ValidatorSet
func (*Backend) VerifyHeader ¶
VerifyHeader checks whether a header conforms to the consensus rules of a given engine. Verifying the seal may be done optionally here, or explicitly via the VerifySeal method.
func (*Backend) VerifyHeaders ¶
func (sb *Backend) VerifyHeaders(chain consensus.ChainReader, headers []*types.Header, seals []bool) (chan<- struct{}, <-chan error)
VerifyHeaders is similar to VerifyHeader, but verifies a batch of headers concurrently. 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 (*Backend) VerifySeal ¶
VerifySeal checks whether the crypto seal on a header is valid according to the consensus rules of the given engine.
func (*Backend) VerifyUncles ¶
VerifyUncles verifies that the given block's uncles conform to the consensus rules of a given engine.
