Using attributes to replicate state?

I’m working on a combat system and I’ve been trying to make use of some of the concepts in client prediction and server reconciliation, it’s not great, but it’s something. Anyways, I’m trying to make it so clients can detect a change and do stuff when the state of another client changes for example ClientB is blocking ClientA needs to do show the blocking effect as well as be able to check ClientB is in the block state.

Here’s the code I currently have which makes use of attributes curious to know how effective this is or if there is a better way I can write this?

-- Switch to blocking state when block button is pressed
   if Input:pressed(inputButtons.blockButton) then
   	player.fsm:blocking(inputButtons.blockButton, os.time())
   end

-- When a state changes we send it to the server 
	self.fsm.onstatechange = function(self, event, from, to, input, t) 
		if from == to then return end
		
		local e = {}
		e.t = eventType.state
		e.state = to
		e.input = input
		e.time = t

		remoteEvent:FireServer(e)
	end

	eventHandler[eventType.state] = function(player, event)
		local playerObj = Server:GetPlayerByInstance(player)

		playerObj.transitions[event.state]()

		local event = {}
		event.t = eventType.state
		event.state = playerObj.fsm.current
		event.player = player

		playerObj:sendEventToClients(event)
	end		

-- Server receives the change and updates its copy of the players state (if it's valid)
	eventHandler[eventType.state] = function(player, event)
		local playerObj = Server:GetPlayerByInstance(player)
		
		-- If the player can enter this state than update the server copy (more checks will need to be implemented)
		if playerObj.fsm:can(event.state) then
			playerObj.transitions[event.state]()
		end
		
		-- Send the new or same state to all clients
		local event = {}
		event.t = eventType.state
		event.state = playerObj.fsm.current
		event.player = player

		playerObj:sendEventToClients(event)
	end	

-- Server updates the state attribute
	self.fsm.onstatechange = function(event, from, to) 
		MessageSystem:sendMessage("stateChange", from, self.character)
	end

	MessageSystem:registerListener("stateChange", function(from, character)
		if self.character ~= character then return end
		self.character:SetAttribute("State", from)
	end)
