Blockchain has unlocked the magic of digital scarcity, and combining that with the power of making the digital goods persistent gives them a potential value that is only limited by how much prestige a wealthy person might place on ownership of the item.

-- Justin Poirier

3 days of up and 19 days of down down down... And the 3 up days were right at the start. Yeah, looking real good.

Nobody wants to pay $300 for a hexadecimal string. That's LITERALLY all you’re buying. All the website does is display a picture of a cat. You're paying hundreds of dollars for a picture of a cat. Let that sink in.

This was a modern tulip bubble. You were buying hex strings that tied to the picture of a cat. People were paying 10-20-30 ETH for a cat picture. 10 ETH was around $4000? For a cat picture. Yeah...

CryptoKitties (Yes, Cute Little Cartoon Cats) on the Blockchain!

Collectible. Breedable. Adorable.

Collect and breed digital cats. Start meow. Buy! Sell! Hold!

Q: What's CryptoKitties? What's the big deal?

CryptoKitties is centered around breedable, collectible, and oh-so-adorable creatures we call CryptoKitties! Each cat is one-of-a-kind and 100% owned by you (*); it cannot be replicated, taken away, or destroyed.

CryptoKitties is built on blockchain technology. You can buy, sell, or trade your CryptoKitty like it was a traditional collectible, secure in the knowledge that blockchain will track ownership securely. But, unlike traditional collectibles, you can breed two CryptoKitties to create a brand-new, genetically unique offspring. It results in something special—just like you!

(*): See Q: Do you really own your CryptoKitties? A: Spoiler: No.

More (Minor) Milestones

  • 2017 Dec/3 - Due to network congestion, we are increasing the birthing fee from 0.001 ETH to 0.002 ETH. This will ensure your kittens are born on time! The extra is needed to incentivize miners to add birthing txs to the chain. Long-term solution will be explored very soon!
  • 2017 Dec/4 - DUE TO CONGESTION ON THE NETWORK WE ARE INCREASING THE BIRTHING FEE FROM 0.002 ETH TO 0.015 ETH. WE HOPE THIS WILL ALLOW MORE KITTENS TO BE BORN ON TIME AS THERE HAVE BEEN SIGNIFICANT DELAYS

If you are going to build consumer [gambling casino] products on the internet [blockchain] then you should not explain why you're using cats, but you should explain why you are not using cats.

Official WikiLeaks CryptoKitties. Purebred WikiLeaks CryptoKitties arrive in time for Christmas.

How it works. Mr. WikiLeaks and Mrs. WikiLeaks are two Generation 0 CryptoKitties. WikiLeaks will keep scarcity by breeding only one kitten per week after the initial Christmas litter of 10 (of which only 8 will be for sale). Kitties can be renamed and resold or gifted by their new owners. Their authenticity can be verified on the blockchain. WikiLeaks CryptoKitties will be auctioned at a variety of prices, starting at the highest bidding price which will decrease over the course of the four day auction or until a buyer acquires the kitty.

Mania to Cooldown

Q: How popular is CryptoKitties?

In December 2017 - CryptoKitties Mania:

CryptoKitties is now the most popular contract on ethereum, accounting for 11 percent of total traffic (transactions).

(Source: CryptoKitties Mania Overwhelms Ethereum Network's Processing, December 4th, 2017)

CryptoKitties make up over 20 percent of all ethereum computations and the app is Ethereum’s most popular by far.

(Source: How CryptoKitties Disrupted the Ethereum Network, December 2017)

In April 2018 - CryptoKitties Cooldown:

The number of active decentralized app (dapp) users [on ethereum] is shockingly low, even for high-profile app like CryptoKitties.

Citing data from DappRadar, Chris McCann reports that CryptoKitties has fewer than 1 000 daily active users (DAU). Granted, interest has sharply declined over the past few months, but he estimates that even at its peak the [CryptoKitties] app likely only had about 14 000 daily users. Neopets, a game to which CryptoKitties is often compared, once had as many as 35 million users.

CryptoKitties marks the beginning of a (massive) digital revolution. To understand why, learn about the blockchain, blockchain, blockchain.

Why we're not doing an Initial Coin Offering (ICO) by Benny Giang (Axiom Zen, Vancouver, Canada), November 2017

CryptoKitties is not holding an Initial Coin Offering (ICO). Instead, we're offering utility from day one and pursuing a sustainable revenue model based on our games' mechanics.

Cryptokitties @ Wikipedia

CryptoKitties offers something similar to a cryptocurrency: each CryptoKitty is one-of-a-kind, 100% owned by the user, validated through the blockchain, and the value can appreciate or depreciate based on the market. Cryptokitties cannot be replicated, taken away, or destroyed.

CryptoKitties & Fun-tier Technologies by Vijay Sundaram, December 2017

These tokens ought to primarily flow to users and partners who participate in a well-designed economy, rather than just speculate on it. Almost by definition this approach will pay off even if the crypto tide goes out.

People are spending $millions on digital cats and here's why it makes sense by Tony Aubé, December 2017 -- Crypto Kitties is about so much more than cats.

The blockchain changes everything we thought we knew about computers. By removing one of the computer's biggest feature - the ability to duplicate information - it opens up computing to a multitude of new, real-world use-cases that would have never been possible before.

KittyHats: Accessories For Your CryptoKitties by Andrew Rangel (CryptoGamer), January 2018 -- Fungible ERC20 assets for your Kitty fashionista

There are accessories ranging from 0.0013 ETH (or $1.72) to Yeezy's shoes which are 1 ETH or (or $1,321). They come in limited quantities and the developers assure there won't be "reprints" or re-releases of the items. [...] Like CryptoKitties, the prices are a problem. The iWatch sticker, which could run them into copyright trouble, is priced at 0.3 ETH or a whopping $396 which is more than a physical Apple Watch.

Zombies eating kitties (or the potential for interoperability in cryptonetworks) by Nick Grossman (Union Square Ventures), March 2018

Bitcoin and cryptocurrencies already sound ridiculous to most people, and virtual "real" kittens made out of cryptocurrency take it a step further. [...] On KittyHats - developed independently from CryptoKitties - you can buy a hat for your kitty. Here's the one I bought [a flat brim hat]. What's particularly interesting is that I don't own the hat, my kitty does.

You own the cat. But the cat owns the hat. Cascading unique digital good ownership. Super interesting.

-- Liad Shababo

CryptoKitties - innovative or idiotic? by Melissa Tranfield, March 2018

Will CryptoKitties be the catalyst for widespread public understanding of blockchain, or merely yet another internet gaming fad strapped to this decade's trending technology?

How Do the Founder Make Money with CryptoKitties?

  • The founder auctioned off 100 founder gen 0 kitties on startup.
  • The founder auctions off a new gen 0 kitty every 15 minutes until reaching 50 000 gen 0 ktties in November 2018. Note: The auction price gets automatically calculated from the last five sales plus 50%.
  • The founder get a 3.75% cut (no minimum) on every transaction (selling auction, siring auction, etc.) on the official CryptoKitties marketplace.

Note: If you buy kitties you do NOT own the pictures (*) just the 256-bit hex string (on the blockchain), thus, the founder can sell merchandise or license the pictures for profit. What a franchise!

Scams, Scams, Scams - The Art of the Steal

Buyer Beware! Seller Beware! Here Be Dragons!

Scam #1: Selling Fake Labeled Cheap Kittens Expensive to Newbies (First Timers)

It's like selling (fake) cheap Gucci handbags for the expensive Gucci price. Best of both worlds. Buy low, sell high :-). Profit!

Example: I list my gen 15 cat for sale and name it "RARE gen 0 SANTA mom" and new people not yet understanding how things work buy it. That was happening ALOT.

Q: Can you please return the cat names to the breeding screen?

Benny Giang: Cat names was an awesome way to have personality in the marketplace but unfortunately, there were too many people taking advantage and tricking new users.

Scam #2: Fake Services Phishing (Stealing) Your Private Keys (Kitties)

Put up a website that offers to find the perfect soul mate (with machine learing) for siring new kitties with the rarest of the rarest traits. Please enter your private key to get started. Thank you! Now you've got new kitties for free. Profit!

REMINDER: Trading or selling kitties off of the CryptoKitties marketplace can put your account at EXTREMELY HIGH RISK. NEVER expose your private key on any website for any matter at all. If you do so, you put yourself in a vulnerable position!

Is CryptoKitties a Scam? Is CryptoKitties a Pyramid (Gambling) Scheme? Is CryptoKittes an Online (Gambling) Casino?

First the official answer from the CryptoKitties F.A.Q.:

Q: Is CryptoKitties a scam?

No, this isn’t a scam. Anyone with insider knowledge of CryptoKitties - including our developers - are banned from participating. This is to prevent anyone from using their knowledge of the breeding algorithm to create the most valuable kinds of cat.

Q: Are CryptoKitties like dollars or like stuffed animals?

CryptoKitties are NOT a cryptocurrency. They're more like a crypto collectible. The real-world analogy for a cryptocurrency is dollars or pounds; a crypto collectible’s real world analogy is closer to stuffed animals beanie babys or fine tulip flower bulps.

As dictated by the contract script on the blockchain, any CryptoKitty you own belongs to you (*). Like any product or property you can own, the market price is determined by what a greater fool is ready to pay (depending on demand, scarcity, and only limited by your asking price).

(Source: CryptoKitties F.A.Q.)

(*): Note: See Q: Do you really own your CryptoKitties? A: Spoiler: No.


And here's an independent ("unofficial") answer:

Q: Is CryptoKitties a pyramid (gambling) scheme?

Yes, of course. It's gambling. CryptoKitties is designed on purpose for viral spreading.

With human nature is what it is - fear of missing out of getting-rich-quick and so on - it works everytime like a charm once the hype starts (and prices go up and up).

More and more new greater fools buy more and more 256-bit hex strings (kitties on the blockchain) until in the end running out of new greater fools paying ever higher prices.

Facebook has more than 1 000 000 000+ internet user. CryptoKitties is world-wide. Will CryptoKitties ever run out of new greater fools?

  • Selling a lot of GEN1-3 for less than .2 | Fire Sale
  • Selling all kitties for .45 ETH - 9 kitties, quick cooldowns, early generations, rare traits
  • Selling account with 9 kitties (GEN1 - 2 cats, GEN2 - 5 cats, GEN3 - 2 cats), price = ETH 1.2
  • Selling almost 100 kitties!
  • Sell all my kitties for a great price!
  • Selling whole Account with 10 ultra amur cats. Perfect Starter. (For only 0.25 ETH). Fastest gets it.
  • Selling all kitties for .45 ETH - 9 kitties, quick cooldowns, early generations, rare traits
  • Selling whole account with 18 good kitties (10 amurs, rare traits, 1 fancy, max gen.3-9) - Make me an offer!

Q: Is CryptoKitties an online gambling casino?

Gambling vs Investing

Investments are generally not considered gambling when they meet the following criteria:

  • Economic utility
  • Positive expected returns (at least in the long term)
  • Underlying value independent of the risk being undertaken

-- What's Gambling @ Wikipedia

For example, the mixing of genomes when breeding (siring) new kitties is a modern "masqueraded" or fun way to roll a dice or spin a roulette wheel. The betting (wagering) on rare traits is a modern "masqueraded" or fun way of betting (wagering) on lucky numbers.

And, of course, the kitties are a modern "masqueraded" or fun way of casino "funny money" tokens rebranded as digital "virtual" cat collectibles or non-fungible tokens (N.F.T.s).

BEWARE: Gambling is fun and addictive. Winning and losing. Up and down. Treat CryptoKittes as entertainment like casino gambling, sports betting or poker cards playing. Do NOT "invest" trying to get-rich-quick or raise the stakes trying to win back what you have lost, and so on.

Fun, Fun, Fun

Questions & Answers

Tech

Q: Couldn't CryptoKitties be hosted on many types of databases besides a blockchain?

A: Crypto-collectibles have key properties that proprietary digital collectibles didn't: longevity, code-enforced scarcity and rules, resistance to actions of sponsoring company. Much closer to non-digital collectibles like baseball cards than pre-crypto digital goods.

-- Chris Dixon

Legal

Q: Do you really own your CryptoKitties?

A: Spoiler: No.

CryptoKitties are made up of two pieces: the DNA written to the blockchain, and the graphics assembled to represent each CryptoKitty. Axiom Zen owns the graphics, and makes it clear you have no rights to those in their Terms of Use.

-- Greg McMullen

Casino & Gambling / "Market & Investing"

Q: What's the cost of playing?

A: Costs:

Fees:

  • 3.75% Sales fee. (When you successfully sell or sire a cat on the marketplace.)
  • Gas fees (**). These are transactions fees. Every time you start a transaction on the blockchain, you have to pay the "miners" to run the task. Transactions with gas fees incl.:
    • Buying a cat / hiring a sire.
    • Breeding.
    • Putting a cat up for auction (sell or sire).
    • Taking a cat down from auction (sell or sire). [Note: Note: If you cat doesn't sell, it stays up for auction until you take it down.]

(*): The breeding fee was at first 0.001 ETH. Due to high transaction traffic on the blockchain the founders had to raise the fee because the breeding fee has to be higher than gas fees to birth a new kitty.

(**): The gas fee is shown before you send off a transaction. It is roughly between $0.30 - $3.00 (depending on blockchain traffic).

Q: What's the population? How many gen0 kitties will there be?

A: 50_000 Gen 0 Kitties

  • CryptoKitties started with 100 founder kitties - see #1 (Genesis!) to #100.
  • Every 15 minutes a new gen0 kitty (also known as "clock cat") gets added (that is, 4 gen0 kitties/hour, 96 gen0 kitties/day, 672 gen0 kitties/week) and sold by (dutch) clock auction (*) until reaching a limit of 50_000 in one year (end of November 2018) - see #1001 for first clock cat.

(*): A gen0 kitty's start price is automatically calculated by the average price of the last five kitty sales, plus 50% and sold by a descending clock auction; see Marketplace / Gen 0.

(Source: Statistical Data on CryptoKitties)

Q: What's a clock auction?

It's an auction with an automatically calculated descending price by clock (that is, the prices depends on the time of the purchase). Sellers choose a high opening bid, a minimum closing bid, and a timeframe for the auction to run. Buyers choose their purchase price along that spectrum by purchasing when the price aligns with their perceived value of the CryptoKitty being sold - as long as someone else doesn't buy it befor. Note: Buyers pay gas when they complete a purchase and sellers pay gas to start an auction.

Q: What make's a kitty good?

A: The generation, cooldown speed, traits, and all affect the overall price and desirability of the kitties. Generally, anything gen(eration) 0/1/2/3/4, with fast/swift/snappy/brisk is a good kitty. Rare traits make it even better.

Generation. The best generation of kitty is Gen 0. The lower the generation number, the better starting cooldown the kitty is born with.

When breeding two kitties together, the resulting generation will be one higher than the highest generation parent. For example:

  • If a Gen 0 and Gen 0 breed, the kitten will be Gen 1.
  • If a Gen 5 and Gen 5 breed, the kitten will be Gen 6.
  • If a Gen 0 and a Gen 5 breed, the kitten will be Gen 6.

Cooldowns. Each time a kitty breeds another kitty it needs a period of cooldown time to recover. The cooldown wait time increases every time a kitty breeds until it reaches "catatonic" cooldown, where it will remain.

Note: Cooldowns - fast (1m) › swift (2m·5m) › snappy (10m·30m) › brisk (1h·2h) › plodding (4h·8h) › slow (16h·24h) › sluggish (2d·4d) › catatonic (1w) - are NOT inherited but depend on the generation, that is,
each new kitty is born with a cooldown based on its generation (gen).

Gen (+) Kids Cooldown Time to Recover
0 · 1 Fast 1 minute
2 · 3 Swift 2 minutes
4 · 5 -^^^- 5 minutes
6 · 7 Snappy 10 minutes
8 · 9 -^^^- 30 minutes
10 · 11 Brisk 1 hours
12 · 13 -^^^- 2 hours
14 · 15 Plodding 4 hours
16 · 17 -^^^- 8 hours
18 · 19 Slow 16 hours
20 · 21 -^^^- 24 hours
22 · 23 Sluggish 2 days
24 · 45 -^^^- 4 days
26+ Catatonic 1 week

Examples:

A gen 2 kitty will start off with a swift 2 minutes cooldown when born, and a gen 14 will be born with a plodding 4 hours cooldown.

A gen 11 kitty virgin will start off with a brisk 1 hours cooldown (slot gen 10·11) when born, but after having 3 kids will end up 3 slots down with a plodding 8 hours cooldown (slot gen 16·17).

Traits. Certain traits are rarer than others, making the Kitty more desirable. As more kitties are bred with these traits and new traits are discovered, the value of each one can change.

Traits include:

  • Body and Tail: Chartreux Cymric Himalayan Laperm Mainecoon Munchkin Ragamuffin Sphynx
  • Pimary Color: Mauveover Cloudwhite Cottoncandy Salmon Shadowgrey Orangesoda Topaz Greymatter Cottoncandy Oldlace
  • Secondary Color: Peach Bloodred Emeraldgreen Granitegrey Kittencream

  • Eye Color / Background Color: Bubblegum Chestnut Gold Limegreen Mintgreen Sizzurp Strawberry Topaz
  • Mouth: Whixtensions Dali Saycheese Beard Tongue Happygokitty Pouty Soserious Gerbil

hotrod (1 223 kitties), daffodil (1 347 kitties) are the three rarest.

  • Fabiano Pereira / Smart Contract Developer
  • Dieter Shirley / Technical Architect
  • Mack Flavelle / Product
  • Benny Giang / Product
  • Layne LaFrance / Product

Q: Where do you see CryptoKitties 6 months from now?

Arthur Camara: 6 months from now: there'll be tons of new genes, fancy cats, new features that enhance the gameplay. Managing larger collections will be easy and fun. Cats of all prices will be meaningful and we'll find new ways for people to play with their kitties. We want to enhance the meaning of ownership and make it even more fun.


Q: We have 365k kitties now and under 196k total sales (kitties traded or sired). That combined with the drop in values suggests that the demand isn't keeping pace with the supply [...] causing the market to tank. What do you think caused the crash? Are you working on strategies to increase kitty values or do you want the value to stabilize at $1 per cat or so as rumored?

Q: Any plans to make the market more sustainable for small investors? Currently, someone who invests only $10 can barely buy two kitties, let alone cover the cost to breed them. To make that worse, the likelihood that they'll be able to sell the offspring is minimal. What's your take?

Q: Any modification in plan regarding the mass supply of Gen 0s overcoming the demand?

Mack Flavelle: To be honest, the market has been unpredictable for users and for us. We don't have any more visibility on what will happen next than any other user.

The market excelled much more quickly than we expected - the Gen 0 pricing is 50% more than the average of the last 5 kitties so it is completely determined by the market not us.

We really do believe that long term the kitties will capture a ton of value for users and fans, but it's important to remember that CryptoKitties is a decentralized game. We have very little control on the economy for good or for bad.

Q1 of 2018 we have plans to stabilize the economy and reduce the volatility - in the long run we believe the kitties will be valuable.

Over time the economy will expand to be truly fun and valuable for high net worth players and new, exploratory players - a bigger, healthier economy creates value for everyone inside it.

Arthur Camara: I believe we're building long term value to CryptoKitties with amazing features that are coming, new ways to play with the kitties, new interactions. And remember: there will only ever be 50,000 gen0 kitties, we are constantly adding features, fancy kitties are constantly being discovered.

Benny Giang: There are some interesting ideas around limiting the supply of kitties that we will explore in 2018.

Q: Please let us have an option to recycle / trash worthless kitties in exchange for something.

Benny Giang: Yup, a "kitty sink" could be useful for the market but there are also various of other viable solutions.

Q: Where do you see CryptoKitties 6 years from now?

Arthur Camara: CryptoKitties will be a global brand (way before that, actually). People will give CryptoKitties to their children on their first birthday. There'll be a complex ecosystem around the game, with lots of features and tools.
