.... protocol for consensus in the symmetric model (which can withstand the strong adversary) is obtained by combining several known ideas and protocols, in particular those in [3] and [6] When compared to the protocol in [3] it is, we believe, simpler, and its correctness is easier to establish (see [14]) Moreover, it works in the less powerful symmetric model and can deal with the strong adversary, whereas the protocol in [6] works only against the intermediate adversary. From the technical point of view, our second result is essentially contained in [11] to which we refer for other ....

....is not so simple, because this model has to consider the daemon as an adversary, and clearly separate what is not deterministic (the daemon) and what is randomized (the protocol) There is no place here to develop such a model; that is left to the complete paper. Some useful elements appear in [22] and [5] Let us just summarize here what is needed for proving such an impossibility result: for an infinite sequence of allowed choices of the daemon, the subset of incorrect computations (according to the specification of the problem) has a strictly positive measure. First, we need some ....

....at any point in an execution is given by the state of all processes and the value of all objects. A process may become faulty at a given point in an execution, in which case it performs no subsequent operations. A more formal description of our model can be given in terms of I O automata [27, 28, 29, 31]. The randomized asynchronous computation model, which includes coin flips, is described in [9] A formal definition of linearizability can be found in [21] An operation of an object type is said to be trivial if applying the operation to any object of the type always leaves the value of the ....

.... ( 1 ) lex ( 2 ) or if (b) 1 is a write, 2 is a read, and ( 1 ) lex ( 2 ) In showing the correctness of ARQ , we use a succinct and effective way of expressing the eventuality of certain outcomes based on the current knowledge. The proof uses a fill notion (also used in [20]) which we use to predict the acknowledgment vector for a current invocation. This notion can be used to great advantage in stating our invariants and in reducing the size of their proofs. Our fill notion produces a virtual acknowledgment from each processor based on taking the actual ....
