Every year, ArcTouch brings together its employees for a three-day hackathon, where groups set out to prototype an idea using new and emerging technologies. This year, we had many blockchain hackathon projects — and we think this speaks to both the growing interest in blockchain by our staff and the potential for companies to benefit from it.
My group chose to implement an identity verification system built on the blockchain. Since we planned to leverage smart contracts, we opted for an Ethereum blockchain. However, for first-round development, using the public blockchain or even the testnet is not always ideal due to long transaction confirmation times. Instead, we looked at a several options for quickly spinning up a private blockchain. By far, the easiest approach is to use a cloud ethereum fast company such as Azure to host a private blockchain network.
Azure makes the setup particularly easy by providing an Ethereum Blockchain Consortium template, which features a configurable number of both mining and transaction nodes. This particular Azure template however, provides a proof-of-work PoW blockchain which, depending on your requirements, ethereum fast company not be the best option for a private blockchain.
This consensus setup works well in a private setting because nodes do not need to compete against each other for the privilege of minting blocks, thus eliminating the processing overhead and energy use that comes with PoW block mining and the ethhash algorithm. Since authorities do not require heavy computing resources, we were able to use a smaller virtual machine size a B1S with the default options.
Once the virtual machine was provisioned, we set up our authority node using the following steps:. Using puppeth, a CLI tool released with geth 1. Pass the address of the authority to the unlock parameter, ethereum fast company for rpcaddr, use the Private IP address of your virtual machine as displayed in the Azure console Networking settings.
Be sure to create an Inbound security rule for port in your network security group to allow you to connect to your authority node using the standard web3. The above process takes about 20 minutes, and results in a fully functional, private PoA Ethereum blockchain in the cloud. This environment is ideal for decentralized application DApp proof-of-concept development, and provides fast and free transactions.
You could easily include other virtual machines in the setup to act as dedicated transaction nodes or additional authority nodes for a more representative network.
But developing a proof-of-concept is only one step toward developing a full commercial blockchain solution. DApp security is a notoriously complex topic, and deploying to a public testnet ethereum fast company testing real world scenarios and verifying correct operation is critical.
Integrating your blockchain-based back end with a mobile app front end also requires some solid strategy. Blockchain presents a unique user experience challenge, in that transactions may take many minutes to confirm depending on the gas price you are willing to pay. BlockFirst blockchain development from ArcTouch helps companies transform their business processes through decentralized apps ethereum fast company ledger technology. Nathan Williams - Nathan Ethereum fast company is a ethereum fast company engineer at ArcTouch, specializing in Xamarin and blockchain development.
Like any credible developer, he brews his own beer ethereum fast company home. Nathan Williams Feb 28, Every year, ArcTouch brings together its employees for a three-day hackathon, where groups ethereum fast company out to prototype an idea using new and emerging technologies.
Once the virtual machine was provisioned, we set up our authority node using the following steps: Install Ethereum and geth sudo apt-get install software-properties-common sudo add-apt-repository -y ppa: Create the genesis block Using puppeth, a CLI tool released with geth 1.

Launched a few days ago, CryptoKitties is essentially like an digital version of Pokemon cards but based on the Ethereum blockchain. Built by Vancouver ethereum fast company San Francisco-based design studio AxiomZenthe ethereum fast company is the latest fad in the world of ethereum fast company and probably soon tech in general.
People are spending a crazy amount of real money on the game. Ethereum fast company third party site tracks the largest purchases made to date on the game.
And like any good viral sensation prices are rising and fluctuating fast. Right now it will cost you about. So now we have people using Ether, an asset with arguably little tangible utility — to purchase an asset with unarguably zero tangible utility. Welcome to the internet in This means users literally own their kittens. Unlike playing Neopets where everything was stored on a central database and your pet was deleted when the company shut down, CryptoKitties is decentralized and will live forever on the Ethereum blockchain.
The game is run via a set ethereum fast company 5 Ethereum smart contracts written by AxiomZen, and users interact with it via their own Ethereum address. Right now the easiest way to do that is by using the Chrome extension MetaMask which gives you the ability to send and receive Ethereum directly in your browser.
This traffic is making it hard to play Ethereum fast company, and a lot of transactions like buying and selling cats are taking longer than usual to process and needing multiple attempts. This will ensure your kittens are born on time! The extra is needed to incentivize miners to add birthing txs to ethereum fast company chain. Long-term ethereum fast company will be explored very soon! And anyone can sell their kittens via an auction, where they pick a starting price and an ending price and the price declines over time until someone buys it.
Kittens can also be created by breeding them, which the game calls Siring. You can put your own kitten up for sire for a specified amount of ether and ethereum fast company can breed with it, and they get the offspring and you get the ether.
The shorter the time the better, since you can sell the offspring sooner and breed again. This means kittens with shorter cooldown time usually sell for more.
Each kitten has a bit genome that holds the genetic sequence to all the different combinations kittens can have. These include things like background color, cooldown time, whiskers, beards, stripes and so on. Some of these genes can be recessive, meaning a kitten without stripes could still breed one with stripes. That means the community is independently deciding what traits are rare by paying a premium for them.
For example, kittens with a gold background have been selling more than kittens with other colors. Users can only self-customize the ethereum fast company of their kitten, and often use this space to advertise rare ethereum fast company like color or generation. Each time a cat breeds the generation increases one.
So the offspring of a Gen 0 kitten would be a Gen 1, and so on. Earlier generation kittens seem to be selling for more money, both for the intangible rareness factor and the tangible fact that earlier generation kittens usually have shorter cool down times.
They also take a 3. Unlike some viral projects, the team behind CryptoKitties was set on building out this product regardless of this hype.
