Quantum Solution To The Byzantine Agreement Problem

A resistant or Byzantine Byzantine protocol or algorithm is a robust algorithm for all types of errors mentioned above. For example, if a space shuttle with multiple redundant processors, when processors give conflicting data, what processors or sets of processors should be believed? The solution can be formulated as a Byzantine protocol tolerant of errors. In this article, we propose a quantum communication protocol to reach a Byzantine agreement between several parties. The striking feature of our protocol compared to existing protocols is that we do not use entanglement to reach the agreement. The role played by states involved in other protocols is replaced in our protocol by a group of semi-honest list distributors. Such a replacement makes the implementation of our protocol more feasible. Moreover, our protocol is effective in that it has reached an agreement in only three cycles, which is a substantial improvement over the alternative protocol, which has no involvement. In the first round, a list of numbers that fills out specific features is distributed to each participant in the list via secure communication. During the second and third rounds, these participants will exchange to reach an agreement.

We present a solution to an old problem in distributed data processing. In its simplest form, a sender must send some information to two recipients, but it only has access to pairs of communication channels. Unlike quantum key distribution, this is not the secret, but the match, and the opponent (one of the recipients or the sender itself) is not outside, but inside the game. With only conventional channels, it is proven that this problem is impossible. The solution uses quantum channels in pairs and cross-qutrits. We also start from the participation of semi-honest list distributors in the minutes. This assumption is the price to pay for not using tangles. Given that small-scale interpenetration can be implemented by current technology, we will explore in the future whether semi-honest distributors could be replaced by small-scale interpenetration. The possible application of our DBA protocol is in the quantum block area [21,22,23]. In the future, we plan to apply our protocol to the quantum blockchain to solve certain problems such as auctioning, lottery and secure calculation of multiple games. We propose a quantum communication protocol to reach a demonstrable Byzantine agreement between several parties.

The essential feature of our protocol compared to most existing protocols is that it uses no tangle. The success of our protocol is based on the distribution of reference list sequences, itself based on the unconditional security of QKD. The way in which the QKD is preserved goes beyond the scope of the document; We can only mention that QKD can in principle be implemented without implication, even if, in some proposals, QKD`s performance is improved by the use of a two-qubit crossover state [16]. That is why, in all cases, the agreement is reached. □ Now, P1,…,Pn parts are taking the following steps to reach an agreement: The Byzantine Agreement is a classic problem that focuses on a single bit of data agreement on a network of n-Displaystyle players, whose T-Displaystyle players may be defective. Each player starts with a bit b i display b_ and the goal is for all non-defective players to emit the same bit of displaystyle (Accord), limiting that d`b i `displaystyle` b_`i` is for a node i `displaystyle i` (validity). The difficulty of this task depends on the error model of the defective players. In a Byzantine agreement, defective players can behave at will (including active protocol break, collusion, etc.). The Byzantine agreement is an important problem in conventional distributed systems, which are used to ensure consistency between distributed data structures.

The Byzantine Memorandum of Understanding is a protocol in distributed computing.
