Constants ¶
const ( // MaxTransactionsPerBlock is the maximum number of transactions per block. MaxTransactionsPerBlock = math.MaxUint16 )
Variables ¶
var ErrMaxContentsPerBlock = errors.New("the number of contents exceeds the maximum number of contents per block")
ErrMaxContentsPerBlock is returned when the maximum number of contents per block is reached.
Functions ¶
This section is empty.
Types ¶
type Block ¶
type Block struct {
// The base of the block.
Header
// Transaction list.
Transactions []*transaction.Transaction
// True if this block is created from trimmed data.
Trimmed bool
}
Block represents one block in the chain.
func NewTrimmedFromReader ¶
NewTrimmedFromReader returns a new block from trimmed data. This is commonly used to create a block from stored data. Blocks created from trimmed data will have their Trimmed field set to true.
func (*Block) ComputeMerkleRoot ¶
ComputeMerkleRoot computes Merkle tree root hash based on actual block's data.
func (*Block) DecodeBinary ¶
DecodeBinary decodes the block from the given BinReader, implementing Serializable interface.
func (*Block) EncodeBinary ¶
EncodeBinary encodes the block to the given BinWriter, implementing Serializable interface.
func (*Block) EncodeTrimmed ¶
EncodeTrimmed writes trimmed representation of the block data into w. Trimmed blocks do not store complete transactions, instead they only store their hashes.
func (*Block) GetExpectedBlockSize ¶
GetExpectedBlockSize returns expected block size which should be equal to io.GetVarSize(b).
func (*Block) GetExpectedBlockSizeWithoutTransactions ¶
GetExpectedBlockSizeWithoutTransactions returns expected block size without transactions size.
func (Block) MarshalJSON ¶
MarshalJSON implements json.Marshaler interface.
func (*Block) RebuildMerkleRoot ¶
func (b *Block) RebuildMerkleRoot()
RebuildMerkleRoot rebuilds the merkleroot of the block.
func (*Block) UnmarshalJSON ¶
UnmarshalJSON implements json.Unmarshaler interface.
type Header ¶
type Header struct {
// Version of the block.
Version uint32
// hash of the previous block.
PrevHash common.Hash
// Root hash of a transaction list.
MerkleRoot common.Hash
// Timestamp is a unix timestamp.
// The time stamp of each block must be later than previous block's time stamp.
// Generally the difference of two block's time stamp is about 15 seconds and imprecision is allowed.
// The height of the block must be exactly equal to the height of the previous block plus 1.
Timestamp uint64
// Nonce is block random number.
Nonce uint64
// index/height of the block
Index uint32
// Contract address of the next miner
NextConsensus common.Address
// Script used to validate the block
Witness transaction.Witness
// PrimaryIndex is the index of primary consensus node for this block.
PrimaryIndex byte
// contains filtered or unexported fields
}
Header holds the base info of a block.
func (*Header) DecodeBinary ¶
DecodeBinary implements Serializable interface.
func (*Header) EncodeBinary ¶
EncodeBinary implements Serializable interface.
func (Header) MarshalJSON ¶
MarshalJSON implements json.Marshaler interface.
func (*Header) UnmarshalJSON ¶
UnmarshalJSON implements json.Unmarshaler interface.
