If you have a question about this talk, please contact Mani Bhesania. This talk presents an overview on our research on blockchain consensus. In particular, the first part of the talk presents background and analysis of blockchain consensus, based on our work-in-progress survey; and the second part of the talk presents our newly designed RepuCoin, an extra resilient blockchain consensus system. In particular, existing proof-of-work (PoW) based cryptocurrencies cannot tolerate attackers controlling more than 50% of computing power in the system at any time, but assume that such a condition happening is “unlikely”. However, recent facts and attacks render this assumption unrealistic. To address this issue, we propose RepuCoin, the first system providing guarantees even when more than 50% of the system’s computing power is temporarily dominated by an attacker. While providing better resilience to known attacks, RepuCoin also achieves a high throughput of 10,000 transactions per second. This talk is part of the Computer Security Seminars series.
