Mnikr - Digital Identity Management 2009 — Presentation Transcript

Mnikr

Reputation Construction Through Human Trading of Distributed Social Identities

Brendan Francis O’Connor SET Corporation The Johns Hopkins University [email_address] Twitter: @USSJoin John Linwood Griffin The Johns Hopkins University [email_address] Twitter: @JLGTwit

We developed a system to coalesce people’s distributed social network personas from across the Internet, then buy and sell shares of people in a stock market to determine reputation.

You, too, can own your own person!

Why do we care about Reputation on the Internet?

Services (Twitter, YouTube, Digg)

Users (Me! Or you!)

Personas (USSJoin, 2Cool4U)

Identities (My Virtual Self)

Who are you (on the Internet)?

“You’re not your job.”

“ You’re not how much money you have in the bank.

“ You’re not the car you drive.”

“ You’re not the contents of your wallet.”

“ You are not your... khakis.”

So who am I?

Mnikr, Part I

The Combining

XFN: A MicroFormat with MacroEffects

XFN

Identities USSJoin @ Twitter USSJoin @ Youtube USSJoin @ Digg USSJoin @ GitHub

Social Graph API

Caveat

XFN data isn’t clean

We have to make sure “me” relationships are bidirectional

We find it acceptable to leave some Identities not fully combined

Some people use it incorrectly for no readily apparent reason

Mnikr, Part II

The Trading

Other Reputation Systems

PageRank (Google)

Windley et al and OpenPrivacy

Attempting to strip context (e.g., eBay-ness) from context-sensitive reputation (e.g., eBay Feedback Score)

Other Reputation Systems http://personas.media.mit.edu

Other Reputation Systems

Accelerando , Charles Stross

This gave us the idea for a reputation stock market

Stock Markets

Big Ideas

If you have cool friends, they can make you cool

Like PageRank

No one ultra-cool user can make you cool

Users have to be invested in the system to make others cool

Prevents Sybil attack

No Negative Commentary

The Sims Online Mafia

Reputation Math

Every value starts at 1

Every share purchase raises the value by 1

Every share sale lowers the value by 1

The purchase price is equal to the value

An Identity can only own 5 shares of another single Identity

Reputation Math

Alice has a share value of 5

Bob buys one share, which costs him 5

Alice now has a value of 6

Bob now sells his share, which gives him 5 points back

Alice now has a value of 5

Dividend Math

Dividends = (value * shares) / 20

Personal Dividends = value / 5

So if Alice owns 3 shares of Bob, whose value is 8, then Alice gets (3*8)/20 = 1 point

Bob also gets 1 point for his value of 8

Dividends are run every 24 hours

Bootstrap

Mnikr: the Social Network

How Big Did It Get? Is 350,000 Big? Is 350,000 Big?

The Kings of Reputation Street Time Between Trades Highest-Valued Identities

Next Steps

Mutual/Index Funds

Derivatives Trading (Short Selling)

Real Money

Majority Shareholder Action Control?

Lee Konstantinou, Pop Apocalypse

Conclusions

Metcalfe’s Law Can Be Bent

The value of a telecommunications network is not necessarily proportional to the square of the number of connected users of the system

Stock Market Seems to Work for Reputation (Good People are Good)
