Make Ethereum massively scalable today with delayed computations

Suppose you're writing a contract which involves a huge amount of participants. As an example, think of an online, blockchain-based Trading-Card Game with tournaments. How would you program a playCard function? You might be thinking of something like this:

function playCard(uint player, uint card){
    ...
    else if (card == PROFESSOR_OAK){
        // shuffles the player's hand on his deck
 shuffleHand(player)

The development of the distributed mass storage subsystem for Ethereum named Swarm was kicked off in October 2014, shortly before Devcon 0 in Berlin, where we presented the design principles, the basic network and protocol architecture as well as the requirements that we aimed to achieve. With the preliminary design finalized by the end of 2014, implementation in Go language began in 2015.

In 2015, we built the foundations of Swarm, consisting of the subsystems for distributing arbitrarily large files across the network with the possibility of subsequent efficient retrieval and
