Ontological Smart Contracts in OASIS: Ontology for Agents, Systems, and Integration of Services (Extended Version)
This work aims to provide ontological capabilities for digital public ledgers and smart contracts, which is an incremental improvement for developers and researchers working with agent systems and blockchain technology.
This paper extends the OASIS ontology with conditionals and ontological smart contracts (OSCs) to model agent responsibilities, authorizations, and agreements. These extensions are applied to enhance digital public ledgers and smart contracts, with a proposed framework leveraging Ethereum and IPFS.
In this contribution we extend an ontology for modelling agents and their interactions, called Ontology for Agents, Systems, and Integration of Services (in short, OASIS), with conditionals and ontological smart contracts (in short, OSCs). OSCs are ontological representations of smart contracts that allow to establish responsibilities and authorizations among agents and set agreements, whereas conditionals allow one to restrict and limit agent interactions, define activation mechanisms that trigger agent actions, and define constraints and contract terms on OSCs. Conditionals and OSCs, as defined in OASIS, are applied to extend with ontological capabilities digital public ledgers such as the blockchain and smart contracts implemented on it. We will also sketch the architecture of a framework based on the OASIS definition of OSCs that exploits the Ethereum platform and the Interplanetary File System.
