System for interacting objects as tokens on a blockchain using a class-based language

In modern object-oriented programming, programs are written using typed objects like classes and instances that interact with one another via rules of composition, inheritance, encapsulation, message passing, and polymorphism. Some embodiments described herein can include a method for tokenizing such modern objects that maintains their interactive properties on a blockchain. It improves upon, and diverges from, the smart contract model used mainly on account-based blockchains today to create a generally-programmable token system that is native to UTXO-based blockchains, where individually-owned software objects interact with other software objects owned by other individuals. These tokenized objects are called jigs. Jigs, an abstraction like objects, enable applications to build their own digital assets that interact with other jigs from other applications. Jogs enable users to own their data as tokens and use their data independent of any one application's complete control.
