VX is an extremely toxic synthetic chemical compound in the organophosphorus class, specifically, a thiophosphonate.In the class of nerve agents, it was developed for military use in chemical warfare after translation of earlier discoveries of organophosphate toxicity in pesticide research.

VR (Russian VX, VXr, Soviet V-gas, GOSNIIOKhT substance No. 33, Agent "November") is a "V-series" unitary nerve agent closely related (it is an isomer) to the better-known VX nerve agent. [1] It became a prototype for the series of Novichok agents .
VX was the only V-series agent that was fielded by the US as a munition, in rockets, artillery shells, airplane spray tanks, and landmines. [ 27 ] [ 29 ] Analyzing the structure of thirteen V agents, the standard composition, which makes a compound enter this group, is the absence of halides .
VE (S-(diethylamino)ethyl O-ethyl ethylphosphonothioate) is a "V-series" nerve agent closely related to the better-known VX nerve agent. It was first reported in 1958 as a pesticide. [1] Like most of the agents in the V-series (with the exception of VX), VE has not been extensively studied outside of military science. [citation needed]

Example of a declared Novichok derivative, researched in Iran in 2016. The agent A-234 is also supposedly around five to eight times more potent than VX. [64] [62] The median lethal dose for inhaled A-234 has been estimated as 7 mg/m 3 for two minute exposure (minute volume of 15 L, slight activity). [65]
A Byzantine fault is a condition of a system, particularly a distributed computing system, where a fault occurs such that different symptoms are presented to different observers, including imperfect information on whether a system component has failed.
