var TxFilterAcceptAll = func(int) bool {
	return true
}

TxFilterAcceptAll accepts all transactions

Functions

func GetDataToSign

func GetDataToSign(blockNum uint64, txFlags, identity []byte) []byte

GetDataToSign appends the block number, Tx Flags, and the serialized identity into a byte buffer to be signed by the validator.

Types

type PolicyEvaluator

type PolicyEvaluator struct {
	*discovery.Discovery
	// contains filtered or unexported fields
}

PolicyEvaluator evaluates the validation policy

func New

func New(channelID string, disc *discovery.Discovery, pp policies.Provider) *PolicyEvaluator

New returns a new Validation PolicyEvaluator

func (*PolicyEvaluator) GetTxFilter

func (p *PolicyEvaluator) GetTxFilter(block *cb.Block) TxFilter

GetTxFilter returns the transaction filter that determines whether or not the local peer should validate the transaction at a given index.

func (*PolicyEvaluator) GetValidatingPeers

func (p *PolicyEvaluator) GetValidatingPeers(block *cb.Block) (discovery.PeerGroup, error)

GetValidatingPeers returns the set of peers that are involved in validating the given block

func (*PolicyEvaluator) ValidateResults

func (p *PolicyEvaluator) ValidateResults(results []*validationresults.Results) error

ValidateResults validates that the given results have come from a reliable source and that the validation policy has been satisfied.

type TxFilter

type TxFilter func(txIdx int) bool

TxFilter determines which transactions are to be validated
