<div>I have found this kind of cryptography recently and I thought you might like it. (As always, no warranties)</div><div><br></div>What is MPC?<div><br></div><div>Participants - peers agree to evaluate a specific function. They will give their data and each one of them will receive part of the evaluation.</div>
<div>One's data and results are kept private from the others.</div><div>No one can cheat, Noone can try to change the rules without the others agreeing.</div><div><br></div><div>This is called an Ideal Functionality.</div>
<div> <a href="http://en.wikipedia.org/wiki/Universal_composability#Ideal_functionality">http://en.wikipedia.org/wiki/Universal_composability#Ideal_functionality</a></div><div><br></div><div>In its essence, it emulates the existence of a trusted party - Government that enforces that participants abide by the rules. </div>
<div><br></div><div>How does this change the way we design new economic alternatives?</div><div><br></div><div>1. We can create economic alternatives that are based on the fact that all information is known. Today each and every corporation withholds information from the general public.</div>
<div><br></div><div>2. If a) We create an economic system based on a function that if not used will have important economic loses for that person.</div><div> b) the function we use doesnt deteriorate the states of the other participants if someone sends false data.(while abiding by the rules)</div>
<div><br></div><div>then any rules participants agree to will be enforcable.</div><div><br></div><div><br></div><div>What are the changes, again?</div><div><br></div><div>We can create an imaginary economic system and we dont have to worry any more about corrupt governments, institutions etc. Whatever the societal structures might be created, they will not be able to be corrupted in such a way as to deviate from the rules of the function.</div>
<div><br></div><div>Why is MPC important ,again?</div><div><br></div><div>We should stop trying to make small changes because we find it difficult to 'enforce' them. We should start thinking big. </div><div><br></div>
<div>Lets start by rejecting anything we knew till now.</div><div><br></div><div>Check this example: <a href="http://viff.dk/doc/applications.html#nordic-sugar">http://viff.dk/doc/applications.html#nordic-sugar</a> for an understanding how it works...</div>

<br></div><div>ps. my economic model relies on the existence of such a non-corruptible government.</div><div><br></div><div><br></div><div><br></div><div>-- <br><span style="font-family:arial, sans-serif;font-size:13px;border-collapse:collapse"><pre style="white-space:pre-wrap">
