Contribution to ISO/WD TS18126 Taxonomy and classification for smart contracts as WG3 Project Leader
Token and asset creation and exchange
The development of ISO/TS 18126 will significantly impact the Blockchain and Distributed Ledger Technology (DLT) landscape by establishing a standardised taxonomy and classification framework for smart contracts. My contributed work addresses the critical need for uniformity in defining and categorising smart contracts, thereby facilitating greater interoperability across diverse DLT platforms. By harmonising terminologies and clarifying key concepts, the standard will streamline the deployment, management, and integration of smart contracts in various sectors, reducing legal uncertainties and technical barriers. Furthermore, this taxonomy is closely aligned with the European Union's legal and regulatory initiatives focused on digital innovation, particularly in areas like tokenisation and smart contracts for secure data sharing and automation. It supports the EU's broader efforts to create a cohesive regulatory environment for emerging technologies. The standard not only reinforces Europe’s leadership role in global blockchain standardisation, but also serves as a foundation for international cooperation, fostering the development of universally accepted frameworks that will drive widespread adoption and trust in DLT solutions such as smart contracts.
