Abstract:
Blockchain technologies are taking the world by storm. Public blockchains, such as Bitcoin and Ethereum, enable secure peer-to-peer applications like crypto-currency or smart contracts. Private blockchain systems, on the other hand, target and aim to disrupt applications which have so far been implemented on top of database systems, for example banking, finance and trading applications. Multiple platforms for private blockchains are being actively developed and fine tuned. However, there is a clear lack of a systematic framework with which different systems can be analyzed and compared against each other. Such a framework can be used to assess blockchains' viability as another distributed data processing platform, while helping developers to identify bottlenecks and accordingly improve their platforms. In this this talk, I shall examine the differences between blockchain design and database systems, including distributed and decentralized, and briefly present the benchmarking framework. I shall also discuss our various works on improving the performance of blockchain systems, and our use of blockchain in the domain of healthcare, namely MediLOT.
