Multi-Threshold Byzantine Fault Tolerance
Proceedings of the 2021 ACM SIGSAC Conference on Computer and Communications Security, 2021 Classic Byzantine fault tolerant (BFT) protocols are designed for a specific timing model, most often one of the following: synchronous, asynchronous or partially synchronous. It is well known that the timing model and fault tolerance threshold present inherent trade-offs. Synchronous protocols tolerate up to n/2 Byzantine faults, while asynchronous or

On the Practicality of Practical Byzantine Fault Tolerance [PDF]
, 2012 Byzantine Fault Tolerant (BFT) systems are considered by the systems research community to be state of the art with regards to providing reliability in distributed systems. BFT systems provide safety and liveness guarantees with reasonable assumptions, amongst a set of nodes where at most f nodes display arbitrarily incorrect behaviors, known as ...
