In recent years, as blockchain adoption has been expanding across a wide
range of domains, e.g., supply chain and digital asset, smart contracts'
confidentiality has now become a fundamental demand for practical applications.
However, while new privacy protection techniques are emerging, how existing

general developers. This paper proposes CLOAK, a pluggable and configurable
framework for developing and deploying confidential smart …
