This paper tackles the asynchronous signature-free Byzantine consensus. One way to circumvent the FLP impossibility result consists in adding a Time-free assumption. This assumption is based on the pattern of messages that are exchanged. In the context of authenticated asynchronous Byzantine systems where at most t processes may exhibit a Byzantine behavior, Moumen and Mostéfaoui provide the main result. They assume at least one correct process p_i, called diamond langle t+1rangle text {-winning}, and a set Q of t correct processes such that, eventually, for each query issued by p_i, any process p_j of Q receives a response from p_i among the (n-t) first responses to that query. The main contribution of this paper is to show that a deterministic solution for the Signature-free Byzantine consensus problem is possible if the system model satisfies an additional assumption that relies on the pattern of exchanged messages. To solve the Consensus problem, we assume a correct process p_i, called diamond langle 2t+1rangle text {-winning}, and a set Q of (2t+1) correct processes (including p_i itself) such that, eventually, for each query issued by p_i, any process p_j of Q receives a response from p_i among the (n - t) first responses to that query. The processes of the set Q may change over time. Based on this assumption, a Signature-free Multivalued Byzantine consensus protocol is proposed. Whereas many time-free protocols have been designed for the consensus problem in the crash model and in the Byzantine Authenticated model, this is, to our knowledge, the first time-free deterministic solution to the Signature-free Byzantine consensus Problem.
