/**
 * A base contract using the internal String representation as it is for the Ledger data, invoke
 * method arguments, and invoke method return type. You can create your contracts based on it. It is
 * recommended to use {@link JacksonBasedContract} in most cases, but you can use this class to
 * achieve faster and more efficient contract execution by avoiding JSON serialization and
 * deserialization.
