Everyone is welcome to attend the RISC seminar of Prof. Aggelos Kiayias, with the title 'Architecting Secure and Efficient Distributed Ledgers'.
Abstract:
The advent of blockchain protocols brought to light a number of applications
that could benefit from a large scale Byzantine resilient consensus system.
At the same time a number of significant challenges were put forth in terms
of scalability, energy efficiency, privacy, and the relevant threat model
that such protocols may be proven secure for.
In this talk I will give an overview of recent and ongoing research in the
area of designing distributed ledgers based on blockchain protocols focusing
on results such as the Ouroboros proof of stake blockchain protocols
(Crypto'17, Eurocrypt'18, ACM-CCS'18, IEEE S&P'19) as well as other related
constructions aiming to improve the interoperability and the incentive
structure of distributed ledgers.
