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)

(dominic: this list of papers was originally recommended to me by Brain Noguchi @bnoguchi, and was a great start to understanding distributed systems)

Here's a selection of papers that I think you would find helpful and interesting:

Time, Clocks, and the Ordering of Events in a Distributed System

The seminal paper about event ordering and concurrency. The important result is that events in a distributed system define a partially ordered set. The connection to what we're working on is fundamental, as this defines how to detect concurrent updates. Moreover, the chosen algorithm to turn the partially ordered set into a totally ordered set defines the conflict resolution algorithm.

Ok, I geeked out, and this is probably more information than you need. But it completely answers the question. Sorry. ☺

Locally, I'm at this commit:

When I added FIRST/NEXT/LAST, it was idiomatic but not quite so fast. This makes it faster. Another little bit of masak++'s program.

	(1) The 80x86 is an Octal Machine
	This is a follow-up and revision of an article posted in alt.lang.asm on
	7-5-92 concerning the 80x86 instruction encoding.

	The only proper way to understand 80x86 coding is to realize that ALL 80x86

	syntax on
	set ruler " Show the line and column numbers of the cursor.
	set formatoptions+=o " Continue comment marker in new lines.
	set textwidth=0 " Hard-wrap long lines as you type them.
	set modeline " Enable modeline.
	set esckeys " Cursor keys in insert mode.
	set linespace=0 " Set line-spacing to minimum.
	set nojoinspaces " Prevents inserting two spaces after punctuation on a join (J)
	" More natural splits
	set splitbelow " Horizontal split below current.
