Pay to Multi Signature contract.

P2PK scripts are used to lock Bitcoin to a multiple public keys. The Bitcoin can later be unlocked using the specified threshold of corresponding private keys.

Lock parameters

• :pubkeys - List of BSV.PubKey.t/0 structs.
• :threshold - Threshold of required signatures.

Unlock parameters

• :privkeys - List of BSV.PrivKey.t/0 structs.

Examples

iex> contract = P2MS.lock(1000, %{pubkeys: @pubkeys, threshold: 2})
iex> Contract.to_script(contract)
