Struct Multisig 

pub struct Multisig {
    pub threshold: u8,
}

Multisig (M-of-N) script template.

Creates scripts that require M signatures from a set of N public keys. The threshold M is stored in the template; the public keys are provided when creating the locking script.

Signature Order

Signatures in the unlocking script must appear in the same order as their corresponding public keys in the locking script. The OP_CHECKMULTISIG opcode walks through keys and signatures in order, matching each signature to the next available key.

Fields

threshold: u8

M — the number of required signatures.

Implementations

impl Multisig

pub fn new(threshold: u8) -> Self

Creates a new Multisig template with the given threshold.

Arguments

• threshold - The number of signatures required (M). Must be 1-16.

pub fn lock_from_keys(&self, pubkeys: &[PublicKey]) -> Result<LockingScript>

Creates a multisig locking script from public keys.

This is the recommended API. Keys are encoded in compressed form (33 bytes).

Arguments

• pubkeys - The N public keys. Must have 1-16 keys, and threshold <= N.

pub fn unlock( signers: &[PrivateKey], sign_outputs: SignOutputs, anyone_can_pay: bool, ) -> ScriptTemplateUnlock

Creates an unlock template for spending a multisig output.

Arguments

• signers - The M private keys to sign with. Must be in the same order as their corresponding public keys appear in the locking script.
• sign_outputs - Which outputs to sign.
• anyone_can_pay - Whether to allow other inputs to be added.

pub fn sign_with_sighash( signers: &[PrivateKey], sighash: &[u8; 32], sign_outputs: SignOutputs, anyone_can_pay: bool, ) -> Result<UnlockingScript>

Signs with a precomputed sighash.

Arguments

• signers - The M private keys to sign with (in pubkey order).
• sighash - The precomputed sighash to sign.
• sign_outputs - Which outputs to sign (for the scope byte).
• anyone_can_pay - Whether to allow other inputs to be added.

Trait Implementations

impl Clone for Multisig

fn clone(&self) -> Multisig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Multisig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl ScriptTemplate for Multisig

fn lock(&self, params: &[u8]) -> Result<LockingScript>

Creates a multisig locking script from concatenated 33-byte compressed public keys.

The params slice must be a multiple of 33 bytes (each key is 33 bytes compressed).
