◆ CTxDestination

typedef boost::variant<CNoDestination, CKeyID, CScriptID> CTxDestination

A txout script template with a specific destination.

It is either:

CNoDestination: no destination set
CKeyID: TX_PUBKEYHASH destination
CScriptID: TX_SCRIPTHASH destination A CTxDestination is the internal data type encoded in a bitcoin address

Function Documentation

◆ ExtractDestination()

bool ExtractDestination	(	const CScript &	scriptPubKey,
		CTxDestination &	addressRet
	)

Parse a standard scriptPubKey for the destination address.

Assigns result to the addressRet parameter and returns true if successful. For multisig scripts, instead use ExtractDestinations. Currently only works for P2PK, P2PKH, and P2SH scripts.

◆ ExtractDestinations()

bool ExtractDestinations	(	const CScript &	scriptPubKey,
		txnouttype &	typeRet,
		std::vector< CTxDestination > &	addressRet,
		int &	nRequiredRet
	)

Parse a standard scriptPubKey with one or more destination addresses.

For multisig scripts, this populates the addressRet vector with the pubkey IDs and nRequiredRet with the n required to spend. For other destinations, addressRet is populated with a single value and nRequiredRet is set to 1. Returns true if successful.

◆ GetScriptForDestination()

CScript GetScriptForDestination ( const CTxDestination & dest )

Generate a Bitcoin scriptPubKey for the given CTxDestination.

Returns a P2PKH script for a CKeyID destination, a P2SH script for a CScriptID, and an empty script for CNoDestination.

◆ GetScriptForMultisig()

CScript GetScriptForMultisig	(	int	nRequired,

const char* GetTxnOutputType ( txnouttype t )

Get the name of a txnouttype as a C string, or nullptr if unknown.

◆ Solver()

bool Solver	(	const CScript &	scriptPubKey,
		txnouttype &	typeRet,
		std::vector< std::vector< unsigned char > > &	vSolutionsRet
	)

Parse a scriptPubKey and identify script type for standard scripts.

If successful, returns script type and parsed pubkeys or hashes, depending on the type. For example, for a P2SH script, vSolutionsRet will contain the script hash, for P2PKH it will contain the key hash, etc.

Parameters

[in]	scriptPubKey	Script to parse
[out]	typeRet	The script type
[out]	vSolutionsRet	Vector of parsed pubkeys and hashes

Returns: True if script matches standard template

◆ fAcceptDatacarrier

bool fAcceptDatacarrier

A data carrying output is an unspendable output containing data.

The script type is designated as TX_NULL_DATA.

◆ MANDATORY_SCRIPT_VERIFY_FLAGS

const unsigned int MANDATORY_SCRIPT_VERIFY_FLAGS = SCRIPT_VERIFY_P2SH

static

Mandatory script verification flags that all new blocks must comply with for them to be valid.

(but old blocks may not comply with) Currently just P2SH, but in the future other flags may be added, such as a soft-fork to enforce strict DER encoding.

Failing one of these tests may trigger a DoS ban - see CheckInputs() for details.
