error-free multivalued consensus with byzantine failures Ash Grove, Missouri

Since number of faulty node is bounded, consensus on most batches can be achieved with small communication complexity [85]. The term "multivalued function" is, therefore, a misnomer because functions are single-valued.

The first one allows the non-faulty processes to reduce the number of proposed values to c, where c is a small constant. To the best of our knowledge, we are the first to show that, for large $L$, error-free multi-valued Byzantine consensus on an $L$-bit value is achievable with $O(nL)$ bits of communication.Do Name* Description Visibility Others can see my Clipboard Cancel Save Sign inSemantic Scholar HomeShareError-free multi-valued consensus with byzantine failuresGuanfeng Liang, Nitin H.

The 26 revised papers presented in this volume were carefully reviewed and selected from 96 submissions. Examples of applications of consensus include whether to commit a transaction to a database, agreeing on the identity of a leader, state machine replication, and atomic broadcasts.

This algorithm is based on the previous binary broadcast abstraction and a weak common coin. Many communication channels are subject to channel noise, and thus errors may be introduced during transmission from the source to a receiver. This is an improvement over the work of Fitzi and Hirt (from PODC 2006), who proposed a probabilistically correct multi-valued Byzantine consensus algorithm with a similar complexity for large $L$. The design of this reduction algorithm relies on two new all-to-all communication abstractions.
