Overview of Dumbo-MVBAs framework Sample Clauses

Overview of Dumbo-MVBAs framework. As shown in Figure 2, the generic framework still follows the idea of dispersal-then-recast: (i) each party disperses its own input value and obtains a lock proof attesting the recast-ability of its own dispersal; (ii) then, the parties can invoke any existing MVBA as a black-box to “elect” a valid lock proof, and then recover the already-dispersed value, until all parties recast and decide an externally valid value. O This generic Dumbo-MVBA? framework presents a simple modular design that can enhance any existing MVBA protocol to achieve optimal communication for sufficiently large input, without scarifying the message complexity and running time of underlying MVBA. In particular, when instantiating the framework with using the MVBA protocol due to Xxxxxxx et al. [2], we can obtain an optimal MVBA protocol that outperforms the state-of-the-art, since it achieves only (nl+n2λ) communicated bits, without giving up the optimal running time and message complexity.
