Reference Architecture for Integrating Computable Smart Contracts with Existing Blockchains

This paper presents a reference architecture designed to integrate computable smart contracts with existing blockchain platforms. The proposed architecture addresses key challenges in the development and deployment of smart contracts, including security, interoperability, and compliance. A central feature of the RA is the introduction of a multichain adapter, which enables seamless deployment of smart contracts across different blockchain environments. By providing a standardized framework, the architecture enhances modularity, accelerates development, and reduces costs while ensuring robust security and regulatory compliance. The main goal of the architecture is facilitating cross-chain deployment and operations of computable smart contracts.
