GTV

Generic Transfer Value (GTV) is a general-purpose protocol for sending and decoding any data structure in a way that postchain can understand it.

GTV is used to express data in:

• Primitive types (integers, strings, byte arrays, etc.)
• Complex types (only array and dictionary)

GTV gets converted to ASN.1 DER when it's sent.
