The BCon (Blockchain Consensus and Beyond: Scalable Secure Consensus & Applications) project seeks to design new methods for achieving consensus in a distributed system in a secure and scalable manner by combining blockchain technologies and traditional consensus techniques based on state machine replication strengthened using hardware security features.
The BCon project is funded by the Academy of Finland (grant 309195) for three years, 2017-2020.
- November 19: The IEEE Computer Society Publications Board has awarded the 2019 Best Paper Award to Secure Systems Group alumni Jian Liu’s “Scalable Byzantine Consensus via Hardware-Assisted Secret Sharing” paper published on IEEE Transactions on Computers. The paper presents FastBFT, a fast consensus algorithm that can be used by blockchains. Congratulations to Jian Liu and Asokan!
