Types ¶
type ChainContext ¶
ChainContext implements Ethereum's core.ChainContext and consensus.Engine interfaces. It is needed in order to apply and process Ethereum transactions. There should only be a single implementation in FURYChain. For the purposes of FURYChain, it should be support retrieving headers and consensus parameters from the current blockchain to be used during transaction processing.
NOTE: FURYChain will distribute the fees out to validators, so the structure and functionality of this is a WIP and subject to change.
func NewChainContext ¶
func NewChainContext() *ChainContext
NewChainContext generates new ChainContext based on Ethereum's core.ChainContext and consensus.Engine interfaces in order to process Ethereum transactions.
func (*ChainContext) APIs ¶
func (cc *ChainContext) APIs(_ ethcons.ChainHeaderReader) []ethrpc.API
APIs implements Ethereum's consensus.Engine interface. It currently performs a no-op.
TODO: Do we need to support such RPC APIs? This will tie into a bigger discussion on if we want to support web3.
func (*ChainContext) Author ¶
Author implements Ethereum's consensus.Engine interface. It is responsible for returned the address of the validtor to receive any fees. This function is only invoked if the given author in the ApplyTransaction call is nil.
NOTE: FURYChain will distribute the fees out to validators, so the structure and functionality of this is a WIP and subject to change.
func (*ChainContext) CalcDifficulty ¶
func (cc *ChainContext) CalcDifficulty(_ ethcons.ChainHeaderReader, _ uint64, _ *ethtypes.Header) *big.Int
CalcDifficulty implements Ethereum's consensus.Engine interface. It currently performs a no-op.
func (*ChainContext) Close ¶
func (cc *ChainContext) Close() error
Close implements Ethereum's consensus.Engine interface. It terminates any background threads maintained by the consensus engine. It currently performs a no-op.
func (*ChainContext) Engine ¶
func (cc *ChainContext) Engine() ethcons.Engine
Engine implements Ethereum's core.ChainContext interface. As a ChainContext implements the consensus.Engine interface, it is simply returned.
func (*ChainContext) Finalize ¶
func (cc *ChainContext) Finalize( _ ethcons.ChainHeaderReader, _ *ethtypes.Header, _ *ethstate.StateDB, _ []*ethtypes.Transaction, _ []*ethtypes.Header)
Finalize implements Ethereum's consensus.Engine interface. It currently performs a no-op.
TODO: Figure out if this needs to be hooked up to any part of the ABCI?
func (*ChainContext) FinalizeAndAssemble ¶
func (cc *ChainContext) FinalizeAndAssemble(_ ethcons.ChainHeaderReader, _ *ethtypes.Header, _ *ethstate.StateDB, _ []*ethtypes.Transaction, _ []*ethtypes.Header, _ []*ethtypes.Receipt) (*ethtypes.Block, error)
FinalizeAndAssemble 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). TODO: Figure out if this needs to be hooked up to any part of the ABCI?
func (*ChainContext) GetHeader ¶
GetHeader implements Ethereum's core.ChainContext interface.
TODO: The Cosmos SDK supports retreiving such information in contexts and multi-store, so this will be need to be integrated.
func (*ChainContext) Prepare ¶
func (cc *ChainContext) Prepare(_ ethcons.ChainHeaderReader, _ *ethtypes.Header) error
Prepare implements Ethereum's consensus.Engine interface. It currently performs a no-op.
TODO: Figure out if this needs to be hooked up to any part of the ABCI?
func (*ChainContext) Seal ¶
func (cc *ChainContext) Seal(_ ethcons.ChainHeaderReader, _ *ethtypes.Block, _ chan<- *ethtypes.Block, _ <-chan struct{}) error
Seal implements Ethereum's consensus.Engine interface. It currently performs a no-op.
TODO: Figure out if this needs to be hooked up to any part of the ABCI?
func (*ChainContext) SealHash ¶
func (cc *ChainContext) SealHash(header *ethtypes.Header) ethcmn.Hash
SealHash implements Ethereum's consensus.Engine interface. It returns the hash of a block prior to it being sealed.
func (*ChainContext) SetHeader ¶
func (cc *ChainContext) SetHeader(number uint64, header *ethtypes.Header)
SetHeader implements Ethereum's core.ChainContext interface. It sets the header for the given block number.
func (*ChainContext) VerifyHeader ¶
func (cc *ChainContext) VerifyHeader(_ ethcons.ChainHeaderReader, _ *ethtypes.Header, _ bool) error
VerifyHeader implements Ethereum's consensus.Engine interface. It currently performs a no-op.
TODO: Figure out if this needs to be hooked up to any part of the Cosmos SDK handlers?
func (*ChainContext) VerifyHeaders ¶
func (cc *ChainContext) VerifyHeaders(_ ethcons.ChainHeaderReader, _ []*ethtypes.Header, _ []bool) (chan<- struct{}, <-chan error)
VerifyHeaders implements Ethereum's consensus.Engine interface. It currently performs a no-op.
TODO: Figure out if this needs to be hooked up to any part of the Cosmos SDK handlers?
func (*ChainContext) VerifySeal ¶
func (cc *ChainContext) VerifySeal(_ ethcons.ChainHeaderReader, _ *ethtypes.Header) error
VerifySeal implements Ethereum's consensus.Engine interface. It currently performs a no-op.
TODO: Figure out if this needs to be hooked up to any part of the Cosmos SDK handlers?
func (*ChainContext) VerifyUncles ¶
func (cc *ChainContext) VerifyUncles(_ ethcons.ChainReader, _ *ethtypes.Block) error
VerifyUncles implements Ethereum's consensus.Engine interface. It currently performs a no-op.
