Types ¶

type Base58 ¶

type Base58 struct {
	Version byte
	Data    []byte
}

Base58 type defines the structure of a legacy or wrapped segwit address

func FromBase58 ¶

func FromBase58(address string) (*Base58, error)

FromBase58 decodes a string that was base58 encoded and verifies the checksum.

type Base58Confidential ¶

type Base58Confidential struct {
	Base58
	Version   byte
	PublicKey []byte
}

Base58Confidential type defines the structure of a legacy or wrapped segwit confidential address

func FromBase58Confidential ¶

func FromBase58Confidential(address string) (*Base58Confidential, error)

FromBase58Confidential decodes a confidenail address that was base58 encoded

and verifies the checksum.

type Bech32 ¶

type Bech32 struct {
	Prefix  string
	Version byte
	Program []byte
}

Bech32 defines the structure of an address native segwit

func FromBech32 ¶

func FromBech32(address string) (*Bech32, error)

FromBech32 decodes a bech32 encoded string, returning the human-readable part and the Data part excluding the checksum.

type Blech32 ¶

type Blech32 struct {
	Prefix    string
	Version   byte
	PublicKey []byte
	Program   []byte
}

Blech32 defines the structure of a confidential address native segwit

func FromBlech32 ¶

func FromBlech32(address string) (*Blech32, error)

FromBlech32 decodes a blech32 encoded string, returning the human-readable part and the Data part excluding the checksum.

type ConfidentialAddress ¶

type ConfidentialAddress struct {
	Address     string
	BlindingKey []byte
}

ConfidentialAddress defines the structure of a generic confidential address

func FromConfidential ¶

func FromConfidential(address string) (*ConfidentialAddress, error)

FromConfidential returns the unconfidential address and the blinding public key that form the confidential address

type Opcode ¶

type Opcode struct {
	Value  byte
	Name   string
	Length int
}

An Opcode defines the information related to a txscript Opcode. opfunc, if present, is the function to call to perform the Opcode on the script. The current script is passed in as a slice with the first member being the Opcode itself.

type ParsedOpcode ¶

type ParsedOpcode struct {
	Opcode *Opcode
	Data   []byte
}

ParsedOpcode represents an Opcode that has been parsed and includes any potential Data associated with it.

func ParseScript ¶

func ParseScript(script []byte) ([]ParsedOpcode, error)

parseScript preparses the script in bytes into a list of parsedOpcodes while applying a number of sanity checks.

type ScriptClass ¶

type ScriptClass byte

ScriptClass is an enumeration for the list of standard types of script.

const (
	NonStandardTy         ScriptClass = iota // None of the recognized forms.
	PubKeyTy                                 // Pay pubkey.
	PubKeyHashTy                             // Pay pubkey hash.
