The following argument types are supported when compiling Ivy to Bitcoin Script:
Bytes: a string of bytes (typically represented in hexadecimal)
PublicKey: an ECDSA public key
Signature: a ECDSA signature by some private key on the hash of the transaction
Time: a time (either a block height or a timestamp)
Duration: a duration (either a number of blocks or a multiple of 512 seconds)
Boolean: either true or false
Value: Some amount of Bitcoins (or, more precisely, some amount of satoshis). Parameters of type Value represent actual Bitcoins that are locked up in a contract.
HashableType: any type which can be passed to hash functions: Bytes, PublicKey, Sha256(T), Sha1(T), and Ripemd160(T).
Sha256(T: HashableType): the result of taking a SHA-256 hash of a value of the hashable type T.
Sha1(T: HashableType): the result of taking a SHA-1 hash of a value of the hashable type T.
Ripemd160(T: HashableType): the result of taking a RIPEMD-160 hash of a value of the hashable type T.
