Functions ¶
Types ¶
type IPos ¶
type IPos struct {
IpcEndpoint string
// contains filtered or unexported fields
}
func (*IPos) APIs ¶
func (c *IPos) APIs(chain consensus.ChainReader) []rpc.API
APIs implements consensus.Engine, returning the user facing RPC API to allow controlling the signer voting.
func (*IPos) Author ¶
Author retrieves the ionchain 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. 返回挖出区块的矿工地址
func (*IPos) Authorize ¶
Authorize injects a private key into the consensus engine to mint new blocks with.
func (*IPos) Finalize ¶
func (c *IPos) 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. 返回最终的区块
func (*IPos) Prepare ¶
Prepare implements consensus.Engine, preparing all the consensus fields of the header for running the transactions on top. 返回共识所需要的区块头，baseTarget
func (*IPos) Seal ¶
func (c *IPos) 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. 尝试补全区块（nonce，签名） 判断是否有出块权
func (*IPos) VerifyHeader ¶
VerifyHeader checks whether a header conforms to the consensus rules. 校验区块头 检查是否符合共识
func (*IPos) VerifyHeaders ¶
func (c *IPos) 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). 与VerifyHeader类似，批量校验区块头，返回 quit channel 用来取消操作，results channel 异步取出结果
func (*IPos) VerifySeal ¶
VerifySeal implements consensus.Engine, checking whether the signature contained in the header satisfies the consensus protocol requirements. 校验是否符合共识规则（nonce，签名）
func (*IPos) VerifyUncles ¶
VerifyUncles verifies that the given block's uncles conform to the consensus rules of the stock ionchain ethash engine.
