Types

type Config 

type Config struct {
	Level encoding.LogLevel `long:"log-level"`
}

Config represent the configuration of the proof of work engine.

func NewDefaultConfig 

func NewDefaultConfig() Config

NewDefaultConfig creates an instance of the package specific configuration, given a pointer to a logger instance to be used for logging within the package.

type Engine 

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

func New 

func New(log *logging.Logger, config Config) *Engine

New instantiates the proof of work engine.

func (*Engine) BeginBlock 

func (e *Engine) BeginBlock(blockHeight uint64, blockHash string, txs []abci.Tx)

OnBeginBlock updates the block height and block hash and clears any out of scope parameters set and states. It also records all of the block's transactions.

func (e *Engine) BlockData() (uint64, string)

func (*Engine) CheckBlockTx added in v0.74.0 

func (e *Engine) CheckBlockTx(tx abci.Tx) (ValidationResult, *uint)

CheckBlockTx verifies if a transaction can be included a prepared/verified block.

func (*Engine) CheckTx 

func (e *Engine) CheckTx(tx abci.Tx) error

CheckTx is called by checkTx in the abci and verifies the proof of work, it doesn't update any state.

func (*Engine) DisableVerification added in v0.73.0 

func (e *Engine) DisableVerification()

func (*Engine) EndPrepareProposal added in v0.74.0 

func (e *Engine) EndPrepareProposal(txs []ValidationEntry)

EndPrepareProposal is a callback called at the end of prepareBlock to revert to the state before prepare block.

func (*Engine) UpdateSpamPoWDifficulty 

func (e *Engine) UpdateSpamPoWDifficulty(_ context.Context, spamPoWDifficulty *num.Uint) error

UpdateSpamPoWDifficulty updates the network parameter for difficulty.

func (*Engine) UpdateSpamPoWHashFunction 

func (e *Engine) UpdateSpamPoWHashFunction(_ context.Context, spamPoWHashFunction string) error

UpdateSpamPoWHashFunction updates the network parameter for hash function.

func (*Engine) UpdateSpamPoWIncreasingDifficulty 

func (e *Engine) UpdateSpamPoWIncreasingDifficulty(_ context.Context, spamPoWIncreasingDifficulty *num.Uint) error

UpdateSpamPoWIncreasingDifficulty enables/disabled increased difficulty.

func (*Engine) UpdateSpamPoWNumberOfPastBlocks 

func (e *Engine) UpdateSpamPoWNumberOfPastBlocks(_ context.Context, spamPoWNumberOfPastBlocks *num.Uint) error

UpdateSpamPoWNumberOfPastBlocks updates the network parameter of number of past blocks to look at. This requires extending or shrinking the size of the cache.

func (*Engine) UpdateSpamPoWNumberOfTxPerBlock 

func (e *Engine) UpdateSpamPoWNumberOfTxPerBlock(_ context.Context, spamPoWNumberOfTxPerBlock *num.Uint) error

UpdateSpamPoWNumberOfTxPerBlock updates the number of transactions allowed for a party per block before increased difficulty kicks in if enabled.
