Can a Smart Contract write on the blockchain a transaction containing not only value but also data between...

I need to implement one (or more if necessary) smart contract(s) that store the information of a pending transaction (sleeping transaction) between two EOAs and generate (wake up) the transaction when a particular action happens. Is this operation possible with solidity? I prefer not to demand the computation to an app (until it is possible)






solidity eoa

          The contract will not have access to the events that happen in the network. Therefore, the wake-up call needs to be sent by an EOA.



          The answer is then that the smart contract can store information about the transaction that needs to be done, but an EOA will need to trigger the contract to start the actions.



          You will need to build an external system that sends the wake-up call. If the trigger is time (for instance, you want the transaction to be executed at a particular time), you can use AION, Ethereum Clock Alarm or Oraclize services.



          Hope this helps.

                    Quarter-circle Tiles

                    Image
                    up vote 0 down vote favorite I have $99$ identical square tiles, each with a quarter-circle drawn on it like this: [asy] size(1.5cm); draw(Arc((2,0),1,90,180),red+1); draw((0,0)--(2,0)--(2,2)--(0,2)--(0,0)); [/asy] When I arrange the tiles in a $9times 11$ rectangular grid, each with a random orientation, what is the expected value of the number of full circles I form? I think this problem has to do with finding the chance any given 2x2 square has a circle, but I can't find it. expected-value share | cite | improve this question asked Nov 20 at 15:03 6minecraftninja 1 2

                    0 I think it's similiar to NFAs. I replace the finite states of the given automaton for start-states for my new automaton. I do it with $epsilon$ -transition from the start state to the actual finite states of the given automaton. The start state of the given automaton will be my accepting(finite) state of my new one. All transitions will be reversed of course to recognize the reversed word. But how do I have to change the stack of the pushdown automaton?
