Cryptokitties Is Causing Ethereum Network Congestion Quartz

Cryptokitties Is Causing Ethereum Network Congestion Quartz

The network congestion forced the games developers, a Vancouver company called Axiom Zen, to raise prices. This made processing the games transactions more attractive to ethereum miners, improving the odds of the transactions being accepted. Some $2.7 million has changed hands on the CryptoKitties marketplace in the six days it has been active, according to data from Crypto Kitty Sales. The developers of the game told Quartz it had 1,165 players on Dec. 1 (Update: the game has 6,600 active players as of Dec. 4, according to Benny Giang of Axiom Zen). 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! CryptoKitties (@CryptoKitties) December 3, 2017 To recap, a unique property of a blockchain-based game like CryptoKitties is the fact that the games collectibles are digital objects that dont depend on their issuer for their existence. This means that CryptoKitties developers could vanish tomorrow, but the kittens would still exist as smart contracts on the ethereum blockchain, with their current owners. This is in contrast to valuable collectibles in popular online games like Counterstrike or World of Warcraft, whose existence and ownership rely on the games publishers maintaining centralized servers storing those digital items. The popularity of CryptoKitties, and the resulting congestion on the ethereum network, lays bare the central challenge for blockchain architects: Decentralizing an application can potentially make it very valuable, as in the case of the immutable kittens in the game. Yet no one has yet designed a way to make these decentralized platforms de Continue reading >>

Sophiatx Ico Kicks Off Following Cryptokitties-fueled Delay

Sophiatx Ico Kicks Off Following Cryptokitties-fueled Delay

SophiaTX ICO Kicks Off Following CryptoKitties-Fueled Delay Business blockchain startup SophiaTX finally kicked off its initial coin offering ( ICO ) on Thursday. SophiaTX had originally scheduled its ICO for Tuesday, but the project had to press pause on those plans due to extreme congestion in the Ethereum network. As been widely reported, the network has struggled to keep up with demand for what is currently its most popular application: a Neopets-style game called CryptoKitties that lets users breed and sell adorable cartoon cats. And as adorable as these cats are, they have become big business. As of the time of writing, users had bought and sold more than $8.5 million worth of kittens , and four had sold for more than $100,000 each. The CryptoKitties frenzy has turned into a serious headache for many ethereum users. Since CryptoKitties launched, the number of unconfirmed ethereum transactions has begun to pile up into a growing backlog, causing significant delays and a spike in the average transaction fee. SophiaTX had not planned for this scenario an incident no one could have foreseen even two weeks ago so the company was forced to delay its ICO by 48 hours while it grappled with how best to handle the precarious situation. SophiaTX CEO Jaroslav Kacina used the incident as an opportunity to demonstrate the perceived need for an enterprise-dedicated blockchain. The recent incident demonstrates why we have chosen to build SophiaTX as a proprietary blockchain technology. Businesses require sufficient speed, security, and features that are required for a mainstream adoption by businesses, currently not provided by either Bitcoin, Ethereum and others, he wrote on the companys blog. Although CryptoKitties-related transactions continue to put a strain on the network, Continue reading >>

Cryptokitties Craze Slows Down Transactions On Ethereum

Cryptokitties Craze Slows Down Transactions On Ethereum

CryptoKitties craze slows down transactions on Ethereum These are external links and will open in a new window A new craze for virtual kittens is slowing down trade in one of the largest crypto-currencies. CryptoKitties lets players buy and breed "crypto-pets" on Ethereum's underlying blockchain network. The game's developers told the Bloomberg news agency that CryptoKitties was a "key step" to making blockchains more accessible. But its popularity has underscored one of the technology's biggest downsides: its lack of scalability. Etherscan has reported a sixfold increase in pending transactions on Ethereum since the game's release, by the Axiom Zen innovation studio, on 28 November. "CryptoKitties has become so popular that it's taking up a significant amount of available space for transactions on the Ethereum platform," said Garrick Hileman, from the University of Cambridge. "Some people are concerned that a frivolous game is now going to be crowding out more serious, significant-seeming business uses." An estimated $4.5m (3.35m) has been spent on the cartoon cats at the time of writing, according to Crypto Kitty Sales . Image caption CryptoKitties is the first game built on Ethereum Think of these rather unpalatable cartoon kittens as unique digital Pokemon cards. The game's developers describe them as "breedable Beanie Babies", each with its own unique 256-bit genome. These crypto-collectibles are also gender-fluid, able to play the role of either the "dame" or the "sire" when bred together. The kitties' unique DNA can lead to four billion possible genetic variations. Some of the varieties created so far look lifelike, with grey striped fur and bulging green eyes. Others are speckled with neon-blue spots or magenta-patterned swirls. Image caption One of the less at Continue reading >>

Cryptokitties Game Takes Ethereum By Storm: Immortal, Bisexual, Breedable Cats To Collect

Cryptokitties Game Takes Ethereum By Storm: Immortal, Bisexual, Breedable Cats To Collect

CryptoKitties Game Takes Ethereum By Storm: Immortal, Bisexual, Breedable Cats To Collect CryptoKitties is a new Ethereum-powered game centered around collectible cats, which became a commercial hit as thousands of cats have been sold grossing more than 5 million dollars in revenue so far. The side effect was that the Ethereum network has been congested hitting all-time highs in transactions. First of all what is CryptoKitties . Well, CryptoKitties are cryptocollectibles, which means you can buy, sell or trade each CryptoKitty like a traditional collectible and be sure that the Ethereum blockchain will track ownership. For the uninitiated, each CryptoKitty is simply a unique cat picture which is 100% owned by somebody. But thanks to the blockchain, the kitty cannot be replicated, taken away, or destroyed. It is... immortal and has a value which is set by the market. To play CryptoKitties all you need is a computer running Firefox or Chrome, a digital wallet browser plugin called Metamask which supports CryptoKitties among lots of other Dapps and of course Ether (ETH) to buy your first kitties. US citizens having a Coinbase account can buy ETH inside Metamask using the Coinbase widget. The rest can only acquire Ether from an exchange and then transfer it to their Metamask wallet. Well, there is no fixed value because, as mentioned earlier, Cryptokitties are collectibles. This means everyone can buy and sell a CryptoKitty at an auction. The owner of a kitty sets a starting price which goes down until the auction ends or another user purchases it. Of course, we need some initial kitties to get things started. The game gives birth to a new CryptoKitty every fifteen minutes. Its price is determined by the average price of the last five Cryptokitties sold plus 50%. These par Continue reading >>

Cryptokitties - Wikipedia

Cryptokitties - Wikipedia

CryptoKitties is a blockchain based virtual game developed by Axiom Zen that allows players to purchase, collect, breed and sell various types of virtual cats. It represents one of the earliest attempts to deploy blockchain technology for recreational and leisurely purposes. [1] The game's popularity in December 2017 congested the Ethereum network, causing for it to reach an all-time high in transactions and slow down significantly. [2] On March 20, 2018, it was announced that CryptoKitties would be spun off into its own company and raised $12 million from several top venture capital firms and angel investors. The investment round was led by New York based Union Square Ventures and San Francisco based Andreessen Horowitz . [3] [4] [5] Whereas CryptoKitties is not a cryptocurrency , it operates on Ethereum s underlying blockchain network, which offers something similar. Each CryptoKitty is unique and owned by the user, validated through the blockchain, and its value can appreciate or depreciate based on the market. CryptoKitties cannot be replicated, taken away, or destroyed. Users can interact with their CryptoKitties, having the ability to buy, sell, and sire (breed) them. A test version of CryptoKitties was unveiled at ETH Waterloo on October 19, 2017, the largest Ethereum hackathon in the world. As of December 2, Genesis, the first and highest selling cat was sold for 246.9255 ETH (~$117,712 USD) on that day. The virtual cats are breedable and carry a unique number and 256 bit distinct genome with DNA and different attributes (cattributes) that can be passed to offspring. [6] Several traits can be passed down including cool down time (how much time is required before a cat can breed), whiskers, fur color, eye shape, eye color and background color.

Etherscan - How Do I Find The Deployed Contract Address For Cryptkitties? - Ethereum Stack Exchange

How do I find the deployed contract address for CryptKitties? I read some version of the CryptoKitties source code on How do I use information only on , and preferably inside MetaMask, to determine the actual address of the deployed KittyCore contract. To be clear, some blogger has told be that this is what I am looking for: However anybody could have deployed that. I am looking to determine which one is actually running behind . If you've actually interacted with their DApp, yet. You can look up your ETH address & look at your transaction history or look up the transaction hash via etherscan.io. This will lead you to the "correct" CryptoKittiesCore deployed smart contract. Which I've checked with ETH address & transactions, and it matches the URL you provided. Before you accept and submit a transaction via MetaMask, you can copy the destination address and look that up via etherscan.io to verify the destination. Attempting to buy a kitty leads to this address: CryptoKittiesSalesAuction EDIT:To further verify that CryptoKittiesCore is indeed that address you listed, we both have verified where the funds get sent to: CryptoKittiesSalesAuction.

Cryptokitties Is Totally Wrecking The Ethereum Network

Cryptokitties Is Totally Wrecking The Ethereum Network

CryptoKitties Is Totally Wrecking the Ethereum Network CryptoKitties a sort of online Tamagotchi breeding game built on top of Ethereum, is now the most used contract on the Ethereum network, making up about 12 percent of the networks transactions and climbing. And now, its popularity is clogging up the network. Join the Bitsonline Telegram channel to get the latest Bitcoin, cryptocurrency, and tech news updates: The games object is to breed valuable kittens and list/sell them on the Cryptokitty exchange, each action contributing to the gas limit of each block. If participation in the Cryptokitty system continues to increase, it could potentially grind the Ethereum network to a halt as blocks fill up and the number of unconfirmed transactions rise. This wont be the first time the throughput of Ethereums network has been seriously tested: The Status ICO launch and several other events have pushed the network to the limit, and caused transaction delays lasting hours and even days. However, no previous stress event on the Ethereum network has held sustained activity and growth. CryptoKitties is designed to encourage many small transactions (the devs monetized by charging an additional 3.75 percent off the top of each tx) and only seems to keep growing since the launch on the 28th of November. Since the games launch, blocks became 100 percent full, and the pool of pending transactions is already in the range of 16-17,000 and steadily climbing. If this game has any staying power with crypto-nerds, then it could choke Ethereum completely, forcing users to set higher gas prices or miners to settle on another massive increase in the default gas limit. Note that the gas limit has already more than doubled since the start of the ICO craze. In fact, CryptoKitties developers have Continue reading >>

How To Code Your Own Cryptokitties-style Game Onethereum

Co-founder at Loom Network. Building scalable blockchains for large-scale online games and social apps Creators of CryptoZombies.io How to Code Your Own CryptoKitties-Style Game onEthereum CryptoKitties has done a great job of demonstrating what blockchains can be used for beyond just simple financial transactions. Im hoping well start to see a lot more innovative uses of the blockchain for games like this in the future, so I wanted to write a quick walkthrough of the code behind CryptoKitties to show how it was implemented beneath the surface. This article is written for developers, and while its not an absolute-beginners introduction to Solidity, I tried to include links to documentation to make it as accessible as possible to developers of all levels. Almost all of the CryptoKitties code is open source, so the best way to figure out how it works is to read through the source code. Its around 2,000 lines total, so in this article Im going to be walking through only the sections I think are most important. But heres a copy of the full contract code on EthFiddle if you want to read through it on your own: Powered by EthFiddle, the #1 Solidity code-sharing siteethfiddle.com If youre not familiar with what CryptoKitties is, its basically a game for buying, selling, and breeding digital cats. Each cat has a unique appearance that is defined by its genes, and when you breed 2 cats together, their genes combine in a unique way to produce an offspring, which you can then breed or sell. The code for CryptoKitties is split into a number of smaller contracts in order to keep related code bundled together without having one single giant file with everything in it. The subcontract inheritance for the main kitty contract looks like this: contract KittyOwnership is KittyBase, ERC72 Continue reading >>

Ethereum's Blockchain Is Jamming Up Because Of A New Game That Lets People Buy Virtual Cats

Ethereum's Blockchain Is Jamming Up Because Of A New Game That Lets People Buy Virtual Cats

Ethereum's blockchain is jamming up because of a new game that lets people buy virtual cats "CryptoKitties," a blockchain-based game that let's users buy and sell virtual cats, is exploding in popularity. It's putting pressure on Ethereum, the blockchain fueled by ether. Just when you thought the world of cryptocurrencies couldn't get zanier, along comes "CryptoKitties." The online cat breeding game, which has been likened to both Beanie Babies and Pokemon, has taken the crypto-world by storm. Based on Ethereum's blockchain, the game allows users to breed, buy, and sell kittens with ether, a rival cryptocurrency to bitcoin. It was created by AxiomZen, a San Francisco- and Vancouver-based company. Just like bitcoin, the game has blown up with $3.3 million worth of transactions. Some kittens are listed on its site for more than 50 ether, or approximately $22,500 at ether's price at the time of this writing. More than 20,000 cats have been sold thus far. "CryptoKitties" appears to be pushing Ethereum to its limits with pending transactions on Ethereum's blockchain reaching new highs since the game exploded in popularity, according to data from Etherscan. "[It's] causing a backlog of transactions,"Josh Olszwicz, a bitcoin trader and writer for Brave New Coin, told Business Insider in a Twitter direct message. The game accounts for more than 10% of the activity on Ethereum's blockchain , according to EtherGasInfo.com. "Ethereum is very actively managed by well-known founders," according toJoe DiPasquale, founder of BitBull Capital, a cryptocurrency fund of funds."I am confident management will be able to improve the transaction speed." "I am surprised by the success of the game," he added. Ethereum's blockchain was designed to provide the basis for a number of use-cases out Continue reading >>

Co-founder of Userfeeds.io the information relevance platform for the Web 3.0 stack enabling token-curated feeds and ranking algorithms. How Userfeeds enables the social layer for Non-Fungible Tokens and why Facebook for Cats (and other Crypto-Characters) is comingsoon. TL;DR The non-fungible token (NFT) revolution pioneered by the Cryptokitties team with ERC721 tokens can go beyond crypto-collectibles and gaming. We present the case for looking at non-fungible tokens as new social avatars or even media brands that can act as uniquely identifiable and tradable channels for distribution of information. Owners of ERC721 tokens will be able to increase the value of their NFTs by producing, curating and distributing information via NFT-based channels and accumulating reputation for their actions. If youre interested in implementing feeds for ERC721s in your app or youre interested in curating information with your cat, please join our social channels to learn more (more details at the end of the article) If youve been following the crypto space in the last few months, you must have heard about the Cryptokitties app that went viral towards the end of 2017. The game is simple and brilliantly executed it allows you to collect and breed digital cats. It became so popular that it briefly overloaded the Ethereum network at some point. The success of the game spawned the entire category of tradable crypto-characters such as crypto-bots, crypto-celebrities and crypto-emojis. However, outside of trading and collecting theres currently not much else their owners can do with them. But what if the owner of the crypto-cat could make it perform other actions such as posting or sharing information and reacting to other crypto-characters. Imagine that the digital cat could tell jokes, bre Continue reading >>

What's With Cryptokitties?

What's With Cryptokitties?

I heard these cryptokitties from my friends complaining about their ethereum transactions being delayed or failed. What's with these kitties and lol I dont know much about them but it looks fun and is only a week old. just sent 50$ worth of ether and am going to give it a shot. will report back after try it out well always go for the most popular exchanges. rather then trying for the new kitties or doggies or any other things like that. and also check for the repute of these kitties before doing business with them. I have just read about those crypto kitties yesterday. This is obviously a game with funny cat cartoons. What the exact purpose or goal is of this game did not came out of the report I had read. But over 15% of ethereum transactions were based on this game, which is insane, after 1 week of introduction. Can you imagine the volume? So I am not surprised at all that they are now complaining. They should have done more investigation to find a protocol, which primary focus is high volume transactions and high speed transcation times. @Mattwald looking forward to your report. To hell with that, lost 0.4 ether sending from cryptopia to my metamask address, no history for transaction, cryptopia shows valid transaction but not to the address. Still waiting on support to get back to me. They are working to fix the problem. I hop we didnt lose our ethereum. Put it's so silly... how could this happen. Now we don't have any quick way to buy cryptos. Ether is for now unstable and btc is to slow. I sendt 1,1 ether 11 hours ago, transaction was validated but etherscan is unable to find the txhash.... FML They are working to fix the problem. I hop we didnt lose our ethereum. Put it's so silly... how could this happen. Now we don't have any quick way to buy cryptos. Ether is Continue reading >>

How To Buy A Cryptokitty: The Complete Guide + Dna Sequencing

How To Buy A Cryptokitty: The Complete Guide + Dna Sequencing

How To Buy a Cryptokitty: The Complete Guide + DNA Sequencing my first cryptokitty, First Parent ofDracula Yesterday I purchased my first cryptokitty on the Ethereum blockchain. Professional Mad Scientist! Thats mykitty! I dont consider myself to be the type of person who gets completely swept away by new internet fads, but when my friend told me yesterday that she made $80 by breeding her cryptokitty (and still retaining ownership), I was seized by the idea that I could earn passive income while I pimped out my virtual cats. So far, Ive earned $2.20 by pimping out my first kitty, First Parent of Dracula. This amount is really low, due mostly to me underbidding my kittys reproductive talents. Im not going to tell you how much I paid for my cryptokitty. I bought Ether early this year and paid about $70 for 1 ETH. Now 1 ETH is worth $450. Lets just say I spent way too much for my very first cryptokitty. I bought mine based on three facts: 1. My cat gave birth to a Dracula. 2. My friend who bought one two days ago told me she made $80 by breeding hers. 3. I love SalvadorDali. I wrote this complete guide after many people on Twitter were begging for answers. Heres my kitty and its name is First Parent of Dracula. Cryptokitties are like snails, meaning that all of them can get pregnant. Theres no male nor female. I made mine into an animated GIF using the free tool, Giphy. Step 1: Install the MetaMask Chrome extension: MetaMask is the most noob-friendly way to connect to the Ethereum blockchain.

How To Breed Cats Using The Smart Contract(mew)

Cats being stuck with Bun in Oven or Resting is a common issue, and it will generally resolve itself within a few hours. But in case you dont want to wait, you can call the smart contract manually using MyEtherWallet. UPDATE: They have removed the CryptoKitties contract from MEW. You can copy the ABI from here: STEP 0: Make sure your cats are ready to breed or the transaction will fail. (Click on the link in step 3 and enter the kitty IDs individually on line 29 isReadyToBreed and click on Query to check.) 1. Go to . 3. Select the CryptoKitties smart contract (the address should match ). 6. Input the kitty IDs of your matron and sire. 7. Select Metamask as your sending option in the bottom. Click Connect to Metamask. 8. Press Write and enter in the breeding fee (currently 0.008 at the time of this post, this breeding fee can change) as the sending value in the popup. 9. Send the transaction and in the Metamask popup, enter your gas price. (See for current gas prices.) Once your transaction is successful, the matron of the breeding pair should have a new Bun in the Oven. Happy breeding! Here is a video walk-through of the process provided by LucyintheSky: Courtesy of DERPYBASTARD and anyone else who contributed to this how-to guide. Continue reading >>
