Blockchain-Empowered Federated Learning for Healthcare Metaverses


Given the revolutionary role of metaverses, healthcare metaverses are emerging as a transformative force, creating intelligent healthcare systems that offer immersive and personalized services. The healthcare metaverses allow for effective decision-making and data analytics for users. However, there still exist critical challenges in building healthcare metaverses, such as the risk of sensitive data leakage and issues with sensing data security and freshness, as well as concerns around incentivizing data sharing. In this talk, we first present a user-centric privacy-preserving framework based on decentralized Federated Learning (FL) for healthcare metaverses. To further improve the privacy protection of healthcare metaverses, a cross-chain empowered FL framework is utilized to enhance sensing data security. This framework utilizes a hierarchical cross-chain architecture with a main chain and multiple subchains to perform decentralized, privacy-preserving, and secure data training in both virtual and physical spaces. Moreover, we utilize Age of Information (AoI) as an effective data-freshness metric and propose an AoI-based contract theory model under Prospect Theory (PT) to motivate sensing data sharing in a user-centric manner.

Empowering blockchained federated learning and big model with quantum computing


To increase the computing power in big model, metaverse, and future internet with blockchained federated learning, we study quantum entanglements and performance modelling for quantum computers through deriving a general spherical coordinate formula for a quantum state of n-qubit register. The associated angle-based n-qubit operation rules on a (n+1)-manifold are established to help developing (e.g., cold atom based) quantum computers, which are simple and efficient in the sense that they reduce the complicated quantum multiplication and division operations to simple addition and subtraction operations just like those used in a conventional computer. The rules for n-qubit operations are realized through measurement-filtering based feedback controls and quantum entanglements with the aim to develop scalable quantum computer chips, where the dynamics of quantum states is governed by a system of stochastic Schrödinger’s equations. The performance models are also derived through the scaling limits (called reflecting Gaussian random fields on a manifold) for n-qubit quantum computer-based quantum storage systems. Examples and simulations will also be provided.

Blockchain: From Theory to Application


Blockchain is a chained data structure consisting of blocks linked in chronological order. Each block needs to maintain an identical, continuously growing, and immutable ledger backup locally; blockchain is a technology that enables the secure sharing of information. Data, obviously, is stored in a database. Transactions are recorded in an account book called a ledger. In this report, we will explain blockchain technology and preliminarily explore its potential application areas.

Implications of Coproduction Technology on Waste Management: Who Can Benefit from the Coproduct Made of Leftover Materials?


In recent years, coproduction technology has been developed and adopted by many third-party coproduct manufacturers (CMs). Coproducts made of leftover materials from traditional manufacturing are strongly attractive to green consumers who are willing to pay a price premium for environmental protection. However, original equipment manufacturers (OEMs) might hesitate to adopt coproduction technology because the coproduct cannibalizes the sales of their traditional products. In this paper, we develop a game-theoretical model to investigate the economic and environmental implications of coproduction that can be leveraged by one OEM or one CM. We find that, from the OEM’s perspective, the dominant strategy can be OEM coproduction, CM coproduction, or No coproduction, which is contingent on the demand from green consumers and the supply of raw materials. We also find that the size of green consumers and the unit cost of raw materials have non-monotone impacts on the CM’s profit. Interestingly, an enlarging size of green consumers might hurt the CM, while an increasing cost of raw materials might benefit the CM. Although coproduction recovers the value of leftover materials, the adoption of coproduction technology increases the total material consumption and the total material waste when the unit cost of raw materials is sufficiently high, making the environment worse off.
