Types

type Block 

type Block interface {
	ID() ids.ID
	ParentID() ids.ID
	Block() []byte
	Bytes() []byte
	// contains filtered or unexported methods
}

func BuildOption 

func BuildOption(
	parentID ids.ID,
	innerBytes []byte,
) (Block, error)

BuildOption the option block [parentID] is the ID of this option's wrapper parent block [innerBytes] is the byte representation of a child option block

func Parse 

func Parse(bytes []byte, chainID ids.ID) (Block, error)

Parse a block and verify that the signature attached to the block is valid for the certificate provided in the block.

func ParseWithoutVerification 

func ParseWithoutVerification(bytes []byte) (Block, error)

ParseWithoutVerification parses a block without verifying that the signature on the block is correct.

type Epoch added in v1.16.56 

type Epoch struct {
	PChainHeight uint64 `serialize:"true" json:"pChainHeight"`
	Number       uint64 `serialize:"true" json:"number"`
	StartTime    int64  `serialize:"true" json:"startTime"`
}

Epoch represents a P-Chain epoch for validator set coordination 

type Header interface {
	ChainID() ids.ID
	ParentID() ids.ID
	BodyID() ids.ID
	Bytes() []byte
}

func BuildHeader 

func BuildHeader(
	chainID ids.ID,
	parentID ids.ID,
	bodyID ids.ID,
) (Header, error)

func ParseHeader 

func ParseHeader(bytes []byte) (Header, error)

type ParseResult 

type ParseResult struct {
	Block Block
	Err   error
}

func ParseBlocks 

func ParseBlocks(blks [][]byte, chainID ids.ID) []ParseResult

ParseBlocks parses the given raw blocks into tuples of (Block, error). Each ParseResult is returned in the same order as its corresponding bytes in the input.

type SignedBlock 

type SignedBlock interface {
	Block

	PChainHeight() uint64
	PChainEpoch() Epoch
	Timestamp() time.Time

	// Proposer returns the ID of the node that proposed this block. If no node
	// signed this block, [ids.EmptyNodeID] will be returned.
	Proposer() ids.NodeID

	// Data Availability fields (v1.1 spec)
	DARoot() [32]byte          // Root of DA commitments
	WitnessRoot() [32]byte     // Root of witnesses/proofs
	MessagesOutRoot() [32]byte // Root of outgoing cross-chain messages
	BlobCount() uint32         // Number of DA blobs in block
}

func Build 

func Build(
	parentID ids.ID,
	timestamp time.Time,
	pChainHeight uint64,
	epoch Epoch,
	cert *staking.Certificate,
	blockBytes []byte,
	chainID ids.ID,
	key crypto.Signer,
) (SignedBlock, error)

func BuildUnsigned 

func BuildUnsigned(
	parentID ids.ID,
	timestamp time.Time,
	pChainHeight uint64,
	epoch Epoch,
	blockBytes []byte,
) (SignedBlock, error)
