Wrapping Trust for Interoperability: A Preliminary Study of Wrapped Tokens

Blockchains are traditionally blind to the real world. This implies reliance on third parties called oracles when extrinsic data are needed for smart contracts. Oracle implementation, however, is still controversial and debated due to the reintroduction of trust and a single point of failure. The blindness to the real world also makes blockchains unable to communicate with each other, preventing any form of interoperability. This limitation prevents, for example, liquidity held in Bitcoin from flowing into DeFi applications. An early approach to the interoperability issue is constituted by “wrapped tokens”, representing blockchain native tokens issued on a non-native blockchain. Similar to how oracles reintroduce trust and a single point of failure, the issuance of wrapped tokens involves third parties whose characteristics need to be considered when evaluating the advantages of “crossing-chains”. This paper provides an overview of the available wrapped tokens and the main issuing procedures. Benefits, limitations, and implications for trust are listed and discussed.

Preliminary Study

A multimedia web-based scenario-learning package is prepared for the students of an engineering course. This learning package is to simulate a scenario, which is close to the students’ learning or future working environment. Using up-to-date information and multimedia technology, it can simulate issues and conditions similar to those encountered in the real world. Students can virtually experience how the actual working environment should be. They can also take this opportunity to study how different equipment are interconnected together and signals flowing between different units. Student can use this virtual environment to understand deeper about the operation and the theory behind. Further explanation will be displayed in hierarchical way to suit different background of students. This online scenario-based learning package is to let all students have chance to virtually immerse in a scenario to enhance their learning and knowledge. Preliminary study shows that this scenario-based learning is well accepted by students and is worth for further study.

This article presents some streamlined and intentionally oversimplified ideas about educating future communication disorders professionals to use some of the most basic principles of evidence-based practice. Working from a popular five-step approach, modifications are suggested that may make the ideas more accessible, and therefore more useful, for university faculty, other supervisors, and future professionals in speech-language pathology, audiology, and related fields.
