Types

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

• Number: an integer between -2147483647 and 2147483647, inclusive.

• 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.
