Byzantine Agreement with Bounded Broadcast
Byzantine Agreement introduced in [Pease, Shostak, Lamport, 80] is a widely used building block of reliable distributed protocols. It simulates broadcast despite the presence of faulty parties within the network, traditionally using only private unicast links. Under such conditions, Byzantine Agreement requires more than 2/3 of the parties to be honest. [Fitzi, Maurer, 00], constructed a Byzant...
متن کاملByzantine Agreement with Median Validity
We introduce a stronger validity property for the byzantine agreement problem with orderable initial values: The median validity property. In particular, the decision value is required to be close to the median of the initial values of the non-byzantine nodes. The proximity to the median scales with the desired level of fault-tolerance: If no fault-tolerance is required, algorithms have to deci...
متن کاملExtending Binary Byzantine Agreement to Multivalued Byzantine Agreement
The concern of this paper is a set of potentially faulty processes that engage in a distributed computation to agree on some piece of information. Each process enters the computation with an initial value. The computation returns a common result value to each correct process. If all correct processes begin the computation with identical initial values, then the result value equals the initial v...
متن کاملVerifying Randomized Byzantine Agreement
Distributed systems increasingly rely on fault-tolerant and secure authorization services. An essential primitive used to implement such services is the Byzantine agreement protocol for achieving agreement among n parties even if t parties (t < n/3) are corrupt and behave maliciously. We describe our experience verifying the randomized protocol ABBA (Asynchronous Binary Byzantine Agreement) of ...
متن کاملCapacity of Byzantine Agreement
Caveat: This report represents work-in-progress, and provides some of our early results on the topic. A more complete version of this report, with additional results not presented in this draft, and improved description of the algorithms and analysis, will be released later this year. This draft version contains known problems with clarity/readability and the descriptions are incomplete/impreci...
