Byzantine consensus vector
WebThe problem of obtaining Byzantine consensus was conceived and formalized by Robert Shostak, who dubbed it the interactive consistency problem. This work was done in 1978 in the context of the NASA-sponsored SIFT project in the Computer Science Lab at SRI International. SIFT (for Software Implemented Fault Tolerance) was the brain child of … http://disc.ece.illinois.edu/publications/approx_consensus_matrix.pdf

Unfortunately, the throughput of Byzantine consensus protocols does not naturally scale well with the number of participants due to the all-to-all nature of their communication requirements. ...

WebByzantine agreement by introducing approximate Byzantine agreement, allowing machines to reach approximate consensus rather than exact consensus. This was motivated by the fact that exact consensus in asynchronous systems was proven to be impossible [5]. Additionally, in synchronous systems, approximate Byzantine consensus can be used … WebChristian Cachin, Daniel Collins, Tyler Crain, Vincent GramoliThe 25th European Symposium on Research in Computer Security 2024 was held in Guildford, UK, an...
Web1. Each process uses a scalar Byzantine broadcast algo-rithm (such as [13, 6]) to broadcast each element of its input vector to all the other processes (each ele-ment is a scalar). The Byzantine broadcast algorithm allows a designated sender to broadcast a scalar value to the other processes, while satisfying the following
