Join the Buffalo Computer Society Chapter and Santa Clara Valley Computer Society Chapter in welcoming Distinguished Visitor, Yuhong Liu, on Thursday November 17, at 6 PM ET, when she gives a virtual presentation which completes our Blockchain Technical Series for 2022.

Topic Summary:
A blockchain consists of a list of blocks that are linked based on cryptography hash and maintained by distributed network nodes, so that the information recorded in these blocks is non-repudiated. After its first conceptualization by Nakamoto in 2008, blockchain has attracted broad attention and been considered as a promising solution to establish a decentralized architecture with security. In this talk, we will discuss some key characteristics of blockchain and a few promising applications of blockchain that can facilitate security and trust among multiple parties. Some examples include applying blockchain to secure software updates for resource-constrained IoT networks; designing a secure and efficient multi-signature scheme to facilitate multi-party approval process on Fabric, an enterprise blockchain platform; and facilitating fair trading of digital-goods via a blockchain based proxy re-encryption scheme.
