What is Byzantine general problem explain in detail?

The Byzantine Generals Problem is a term etched from the computer science description of a situation where involved parties must agree on a single strategy in order to avoid complete failure, but where some of the involved parties are corrupt and disseminating false information or are otherwise unreliable.

Does proof of stake solve the Byzantine Generals Problem?

First implemented in 2012, Proof of Stake (PoS) is another blockchain consensus protocol that aims to solve the Byzantine Generals Problem. Unlike PoW-based networks, PoS-based networks don’t rely upon cryptocurrency mining. Instead, a process known as staking is used.

What is Byzantine agreement problem and its solution?

To achieve reliability, the fault-tolerance scheme of the distributed computing system must be revised. This kind of problem is known as a Byzantine agreement (BA) problem. It requires all fault-free processors to agree on a common value, even if some components are corrupt.

What is a Byzantine fault or failure )? Why might a Byzantine failure be more difficult to deal with than fail silent one?

A fail-silent fault is one where the faulty unit stops functioning and produces no ill output (it produces no output or produces output to indicate failure). A Byzantine fault is one where the faulty unit continues to run but produces incorrect results. Byzantine faults are obviously more troublesome to deal with.

What is Byzantine agreement problem explain the two popular Flavours of the Byzantine agreement problem?

There are two other popular flavors of the Byzantine agreement problem – the consensus problem, and the interactive consistency problem. The consensus problem differs from the Byzantine agreement problem in that each process has an initial value and all the correct processes must agree on a single value [20,25].

What is Byzantine failure in distributed systems?

A Byzantine fault is defined as an arbitrary fault that occurs during the execution of an algorithm by a distributed system. When a Byzantine failure occurs, the system may respond in any arbitrary way unless it is designed to have Byzantine fault tolerance.

Why is it called the Byzantine Generals Problem?

The term takes its name from an allegory, the “Byzantine Generals Problem”, developed to describe a situation in which, in order to avoid catastrophic failure of the system, the system’s actors must agree on a concerted strategy, but some of these actors are unreliable.

What is a Byzantine system?

adjective [usu ADJ n] If you describe a system or process as byzantine, you are criticizing it because it seems complicated or secretive.

What is two generals problem explain Byzantine fault tolerance?

How do you solve Byzantine Generals Problem?

Bitcoin uses a Proof-of-Work mechanism and a blockchain to solve the Byzantine Generals Problem. Bitcoin’s ruleset is objective, so there is no disagreement about which blocks or transactions are valid, allowing all members to agree on a single truth.

Why are complicated things called Byzantine?

Byzantine, as you said, refers to a system which is unnecessarily complex and not worth understanding. History tells us: In the Middle ages, the bureaucratic Roman rule resulted in the Byzantine empire. The meaning was taken from the way the Byzantine Generals used to solve their problems.

What is Byzantine fault tolerance algorithm?

Asynchronous byzantine fault tolerance (ABFT) is a property of Byzantine fault tolerant consensus algorithms, which allow for honest nodes of a network to guarantee to agree on the timing and order of a set of transactions fairly and securely.

What is the Byzantine generals’ problem (BGP)?

The Byzantine Generals’ Problem (henceforth mentioned as BGP) is a classic problem faced by any distributed computer system network. We have already discussed that Bitcoin is a decentralized, peer to peer distributed system. Decentralization is the core principle of Bitcoin and this is achieved only through distributed system.

How did the Byzantine army communicate with each other?

The Byzantine army has completely encircled the city. The army has many divisions and each division has a general. The generals communicate between each as well as between all lieutenants within their division only through messengers. All the generals or commanders have to agree upon one of the two plans of action.

What is practical Byzantine fault tolerance?

This form of consensus is known as the Practical Byzantine Fault Tolerance (PBFT). Practical Byzantine Fault Tolerance assures a liveness in the network with at least 67\% trustworthy nodes, but also works in an asynchronous context.

Do generals want to attack or retreat?

However, while some generals want to attack, others may want to retreat. In the official description of the Byzantine Generals’ Problem (which you’ll find on page three of the aforementioned paper), there is a leader-follower set-up. In order to achieve consensus, the commanding general and every lieutenant must agree on the same decision.
