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.

Section du cône ou projection du cercle. En géométrie, une ellipse est une courbe plane fermée obtenue par l’intersection d’un cône de révolution avec un plan, à condition que celui-ci coupe l'axe de rotation du cône ou du cylindre : c'est une conique d'excentricité strictement comprise entre 0 et 1. On peut également la définir comme le lieu des points dont la somme des distances à deux points fixes, dits foyers, est constante (sa construction par la méthode du jardinier est très simple). Dans la vie courante, l’ellipse est la forme qu'on perçoit en regardant un cercle en perspective, ou la figure formée par l’ombre d'un disque sur une surface plane. On retrouve aussi, en première approximation [ 1 ] , des ellipses dans les trajectoires des corps célestes (planètes, comètes ou satellites arti...
