Amazon Web Services (AWS) is a cloud computing service provided by Amazon, the well known e-commerce giant. As you can see, the registration process is very handy, since you can sign-in with your existing Amazon account.You may notice that AWS offers the EC2 service free for 750 hrs/month, for 12 months. However, that is for the Linux t2.micro instance. That is good for testing, but not for mining Ethereum. I will tell you later what instance to select to maximize the GPU power. Once you have registered on AWS , you will be presented with a big list of the services offered by Amazon. Click on EC2 (stands for, Elastic Compute Cloud), that will give you GPU horsepower for mining the Ethereum blockchain. ###Step 2 - Setup the pre-built AMI (Amazon Machine Image) on AWS EC2 An Amazon Machine Image (AMI) "provides the information required to launch an instance, which is a virtual server in the cloud". For our purposes, we need to use the following AMI: IMAGE: ami-2cbf3e44 for US-East (Ubuntu Server 14.04 LTS (HVM) CUDA 6.5) STORAGE: Use at least 8 GB, 20+ GB recommended How can we find it? To find a Linux AMI using the Images page: From the navigation bar, select US East (N.Virginia); In the navigation pane, click Images -> AMIs; Switch to Public Images next to the search filter (the default is "Owned by Me" which will be at first empty, since you do not yet own any AMI) Click on the search filter and then (search by) AMI ID -> ami-2cbf3e44 Note: Make always sure you are in the correct region (US East, N.Virginia as we said) otherwise you will not see the AMI we are insterested in on the list. The ami-2cbf3e44, like all the ubuntu 14.04 images, is supported by Ethereum Frontier, but in addition this pre-built AMI has all the NVIDIA GPU drivers, OpenCL, etc... all pre-instal Continue reading >>

How To Mine Ethereum In 5min

How To Mine Ethereum In 5min

Surprisingly, all you need is an AWS EC2 instance to start mining Ethereum. Im sure youve already heard of the cryptocurrency craze way before reading this post. Cryptocurrencies are slowly and quietly revolutionizing the way financial systems and transactions work (and should work in my opinion). With Bitcoin hitting its $6K mark not awhile ago, a current total of $158B in market cap and hundreds of ICOs (Initial Coin Offering) conducted since August, its sure to say theres a bubble in the cryptocurrency space. Whats more, is that it doesnt seem this bubble is going anywhere, anytime soon. As you can see in the graph below, the total market cap of cryptocurrencies has grown from under $50B to over $150 in under a year! So what would be the best way to enter this space and enjoy the growth? Im not a cryptocurrency expert, however, from my research Ive found that the answer is pretty clear across all opinions: If youre looking for quick earnings, just invest incoins. However, due to this ever-growing crypto market, mining in the short term could lead to significant earnings in the long term. Personally, Im very interested in Ethereum , and have found an effortless way to start mining it quickly on AWS! This post will walk you through the process. But before we start, lets go over some basics. If youre already familiar with them, just scroll down. Ethereum is an open software platform based on the blockchain technology that enables developers to build and deploy decentralized applications. The advantage of Ethereum over Bitcoin, is that it can support many different types of decentralized applications. Ethereum has the second largest market cap after Bitcoin, and has gained massive growth in the last year with over 230% as you can see below: However, increasing growth in Continue reading >>

Designing The Architecture For Your Ethereum Application

Designing The Architecture For Your Ethereum Application

Developer and Security Researcher at Zeppelin Solutions. Designing the architecture for your Ethereum application As you are beginning with Ethereum development, and after going through some of the many excellent tutorial posts out there, you are faced with the challenge of building your first Ethereum-based app. This brings up a set of new challenges around designing the architecture and layout of your application: traditional client-server applications now have a third new component in the mix, the blockchain. In this article Ill cover some of the most traditional scenarios for Ethereum applications, which arise from the different interactions between these three components. Ill discuss serverless apps, browser plugins, private nodes, offline signing, and other issues that play a role when designing the layout of your solutions. The canonical flavour of an Ethereum app is a serverless one, where the entire flow of your app happens entirely between the client and the blockchain. The first step here is to actually distribute the client code to your users. The easiest way is to set up a static page that contains a web3-enabled web app. Such page can be hosted anywhere: AWS S3 , Google Cloud , Github pages , other cloud providers, or your own server. Furthermore, if you can count on your clients having either bzz or ipfs protocol support, you can even disitribute it via Swarm or IPFS for total decentralization. Next step is for the app to be able to read information from the blockchain, which, as you already know, requires a connection to an active Ethereum node. This will be set by your web3 provider , which is the piece that handles the actual web3 connection to a node. Now, some of your users may already have an established connection to a node, for instance, via the Continue reading >>

Ethereum Is The Aws Of Blockchains

Ethereum Is The Aws Of Blockchains

Father, Entrepreneur, Developer, CTO of Waysay, 7 Yrs @ Salesforce & ExactTarget I hate reading crypto articles that preclude the meat of the story with the entire history of Bitcoin and blockchain only to leave you with the new information appended at the end hmm, kinda like a blockchain no? Lets just SegWit this one and assume you know enough about blockchain to understand why the technology is important. Why has the price of Ether gone up ~800% since January1st? Answer: Investors are speculating that blockchain technology will become ubiquitous across all industries, in our daily lives and in every nook and cranny of the global economy. So, if youre an investor that believes the prevailing theory that this Blockchain thing is BIG, like internet 3.0 BIG, what specifically do you bet on? Answer: Ethereum and specifically its crypto-currency Ether (ETH) Ethereum is like Amazon Web Services for blockchain technology. Organizations looking to harness blockchain(s) need not worry about implementing their own proprietary blockchain network if they build their solution on Ethereum. Theyll pay a small fee in the form of gas to the network in exchange for executing the logic contained within their smart contracts programs that run on the Ethereum Virtual Machine, written in Solidity, a javascript like language. This paradigm can be thought of the same way that Amazon Lambda works today a function that waits in the Amazon cloud and executes its logic when called upon. With Ethereum however, the cloud is decentralized - there is no Amazon like entity that owns the network or infrastructure. Its made up of nodes that can be owned and operated by anyone using the laptops, Raspberry Pis and desktops we already have. In the near future our phones will also join in before long, well Continue reading >>

Ethereum Mining On Aws In5mins

Ethereum Mining On Aws In5mins

simply curious about new technology on the block If you have come into this post, you must have heard of bitcoin mining. Bitcoin mining refer to using a node to verify transactions, compile them to a block, solve computational puzzles and submitting the block to the network for a block reward. Most of the effort in the step above are in solving those computationally intensive puzzles. However, Bitcoin mining is no longer feasible for normal folks like you or me as the optimal hardware to mine is ASIC (Application-Specific Integrated Circuit) specially designed for solving for those computational puzzles. Using your own CPU or GPU will result in higher cost (electricity and hardware) than the potential reward. Ethereum is a blockchain network, there are plenty of articles out there to describe the differences of Ethereum over Bitcoin. The main advantage is the blockchain ability to manage not just currency, but any possible item such as DNS in a decentralised manner. Ethereum miners will also have to do exactly the same things as what Bitcoin miners does; except for those puzzles which require not just computational power, but also memory as well. This reduces the competitive advantage of ASIC over GPU. Lets get started on how to mine some Ether on AWS! Change your zone to US East (N. Virgina) as it appears to have the cheapest price for our instance type. Proceed to AWS, under EC2 console, select Spot Requests. Under AMI: Search for ami-84f819f9 in community AMIs Click Next and launch the instance. By this step, you should see a instance coming up. The reason why we choose ami-84f819f9 under AMI is to get an image that has cuda and ethereum client installed the moment you start your instance. You can do a history command to look at the commands ever typed or ps aux to Continue reading >>

Is Ethereum Gpu Cloud Mining With Aws, Hetzner Or Ovh Profitable?

Is Ethereum Gpu Cloud Mining With Aws, Hetzner Or Ovh Profitable?

Is Ethereum GPU Cloud Mining with AWS, Hetzner or OVH Profitable? Is Ethereum GPU Cloud Mining with AWS, Hetzner or OVH Profitable? Recently I discovered that two cloud hosting providers, Hetzner , based in Germany, and Ikoula , based in France, offer cloud-based GPU plans, as part of their dedicated server offerings. I was curious to see if these plans would be economically worthwhile for Ethereum cloud mining, so I ran some hypothetical projections to test this idea. I was also intrigued to see if these product offerings could be an alternative to the Ethereum cloud mining plans which have popped up online and have received a lot of negative coverage. Many of these contracts do not make economic sense. Lastly, I was interested to see if they could show more potential profit when compared to mining Ethereum with Amazon Web Services (AWS), which is quite unprofitable according to multiple articles that Ive read. Important:to keep the projections really simple, I did not account for Ether price changes or mining difficulty changes. I assumed the conditions today would be static for the next 12 months. This is obviously not realistic! However my goal was to test if the plans make sense given the conditions at the time of publication, so this was enough for an initial quick test. If you are curious about how I chose certain numbers for this test, such as has rates for different GPUs, Ether generated per month, and so on, see the notes at the end of the article. Hetzner is a long established web hosting provider based in Germany. They have a decent reputation, so I was excited to test their new GPU offer. Their GPU plan includes a single GTX1080 GPU, theres an initial setup cost of 99, and the ongoing monthly cost is 99. The setup takes approximately 1 week according to th Continue reading >>

Two-node Setup Of A Private Ethereum On Aws With Contract Deployment (part 1)

Two-node Setup Of A Private Ethereum On Aws With Contract Deployment (part 1)

From time to time I plan to emulate an Ethereum environment. The idea behind is to observe how Ethereum nodes work to each other, and how different accounts interact in transaction and contract deployment. For testing, most contract deployment example nowadays is mainly on testrpc or testnet, but how the contract works among nodes is still new to me. I deploy this two-node setup on AWS. As I do not use any special features on AWS, it should be applicable to another cloud environment. My setup is inspired by the work from JJs World ( link ), and after testing this for several times with modification, I document the whole process I have done, and share some experience here about the whole process. I also use the Voting contract developed by Mahesh Murthy ( link ). This is a simple contract that best illustrates how a contract works in the chain. This by no means is a detailed step-by-step guide. I omit certain steps and make reference to some work done by others. For example, the detailed operation of AWS EC2, including launching a new instance with a setup like access key, security group, etc. can be found here ( link ). Part 1: Create a 2-node Ethereum network with private blockchain, and accounts on the two nodes can send ether to each other. Part 2: Deploy a contract from one node, and both accounts can access and execute functions on this contract. Use t2.medium (2 vCPU, 4 GB RAM) with default 8G SSD. Pick Ubuntu OS. Make sure that the two nodes are with the same security group, which allows TCP 30303 (or 30000-30999 as I may use more ports on this range). Port 30303 by default is for peering among nodes. I first tried t2.micro as it is the free-tier offer. However, mining was not successful (DAG loop without ether reward). I next tried t2.small and mining worked. H Continue reading >>

Dapp Development - Is There A Platform For Hosting Apis Similar To Aws Lambda, Only Decentralized? - Ethereum Stack Exchange

Dapp Development - Is There A Platform For Hosting Apis Similar To Aws Lambda, Only Decentralized? - Ethereum Stack Exchange

is there a platform for hosting APIs similar to AWS Lambda, only decentralized? Completely decentralized you meant? Igor Barinov Jun 6 '17 at 15:39 Yes Igor, I added a clarification as a comment to Eric's answer. Noam Jun 7 '17 at 4:48 Your question isn't very clear. Any Dapp is by definition decentralized (Decentralized Application). It consists of one or more contracts that live on the Ethereum blockchain and can be interacted with via web3 enabled browsers like Mist. Meaning as the end user, your client connects directly to your Ethereum contract(s) via the web3.js library, which in turn acts as an interface for JSON-RPC methods that interact with Ethereum nodes. As far as AWS Lambda specifically, it serves a different purpose then Ethereum altogether. When you talk to a contract in Ethereum in the EVM (Ethereum Virtual Machine), the only work that other nodes are concerned about is the verification of changes in the contract's state. Meaning, if you run a function that adds 1+1 and return it, you are not changing the state. Thus the addition runs client side, on your machine. But if you were to assign that value to an unsigned 32 bit integer with a value of 5 you change the state, which must be verified by the network and thus requires gas as a financial incentive to do so. Consider the following example: Contract myContract {uint32 i = 5; function CalculateSum(){ // This calcuation is run by the client. // j has local scope because it is in the function, // meaning assigning to j does not change the contract state, // and therefore this calculation costs no gas: uint32 j = 1 + 1; // This calculation is also run by the client, // but because i is scoped to the contract // by assigning it the client-calculated value of 2, // we require the network to verify the chan Continue reading >>

Ethereum's Potential: Possibly Revolutionary

Ethereum's Potential: Possibly Revolutionary

Ethereum's Potential: Possibly Revolutionary Ethereum might revolutionize business and technology, or it may be merely a transitional platform displaced by other blockchain technologies. Innovate and Thrive: How to Compete in the API Economy REGISTER > The world of Ethereum , to be sure, has an element of the eccentric. Ethereum is a technology started 24 months ago by a 21-year-old college dropout, Vitalik Buterin . Among the facts listed on his slender bio: in 2011 he won third place in a high school programing competition. Yet Ethereum is now supported by JP Morgan Chase and a bevy of tech titans. The market cap of its currency, Ether, hovers around $20 billion down from its $37 billion cap a month ago. There are Ethereum cryptocurrency miners who rent Boeing 747s to rush delivery of the super-charged graphic cards they need for their rigs. Ethereum is promoted by the Ethereum Enterprise Alliance , which sounds like a group Spock himself would have enjoyed. Ethereum advocates herald it a world computer. This decentralized peer-to-peer platform serving finance, retail, even the arts will partner with cloud computing to launch technologys next era. They claim the platforms smart contracts (self-executing code that needs no human assistance) provides rocket fuel for business transactions. The word Ethereum drives from the Latin root ether, meaning the upper pure, bright air. In olden times one inhaled ether before surgery to enter a painless dreamscape. Funny, but Ethereum may fade like a burst of ether. The challenges it faces are wildly complex, from technical to legal to competitive. And those are just the known problems; no telling what unknown obstacles will arise. Yet deep pockets dont seem worried: the pile of money pouring into Ethereum is considerably larger t Continue reading >>

Best Possible Way To Launch The Ethereum Mainnet Node On Aws

Best Possible Way To Launch The Ethereum Mainnet Node On Aws

Best possible way to launch the ethereum mainnet node on AWS I have multiple applications running on my local system. I want to make them live, I need ethereum main net node of my own. I launch the ethereum node on AWS server using supervisory mode but it doesn't work as I think. Can someone suggest the proper, safe way to launch the node with maximum throughput? And what will be the best configuration of the server required? Ubuntu Server 16.04 LTS (HVM), SSD Volume Type - ami-10547475 250 GB (currently about 60gb is being used) nginx reverse proxy server: for ssl/https access (for my site which is https) I am using parity instead of geth. Parity syncs more quickly, is usable within a few hours. I was previously using geth, which took days and often had failures during initial sync. Parity, for me, is much more reliable. I have never had a problem setting up a new node/initial sync. Docker resulted in delays: I also created a docker/parity node but I found that this resulted in delays. There would be a lag in connecting to the node as a web3 provider, which also interfered with event watchers that were connected to the node (i.e. events not caught; if the node fell behind and caught up, then events in the catching up were not caught by event watchers). So far, my setup has been running pretty well, but my app does not have a massive amount of users. We are scaling within the next few months and so will be testing the limits of how many users can connect to the node fairly soon. If scalability is a problem, then I'm considering setting up multiple nodes and using a load balancer, if that ever becomes required. Continue reading >>

Use Go-ethereum To Setup An Ethereum Blockchain On Aws - Part 1

Michael Gord | ethereum, blockchain, geth, aws, cloud, private blockchain, development, go-ethereum Use Go-Ethereum to Setup an Ethereum Blockchain on AWS - Part 1 Often in a blockchain development cycle you will need to put your blockchain on the cloud to enable other nodes to attach to it for testing and development, or for other miners to mine for proof of work blockchain. The two most popular cloud providers for a blockchain solution are Amazon Web Services (AWS) and Microsoft Azure. Both have the option to start with a free trial and to only pay based on your usage. This is a three part blockchain development tutorial series on Ethereum that will focus on how to launch your own Ethereum blockchain using Geth on an AWS server, then connect it to another node to start mining or interact with the same smart contracts. This first tutorial will explain how to first configure and connect to your Amazon Virtual Machine. The second section will explain how to install and configure your Ethereum blockchain using Geth on Ubuntu. The third section will walk through how to connect a second node to your cloud instance of Ethereum.

Ethereum Truffle Pet Shop Dapp Running On An Amazon Ec2 Instance

Ethereum Truffle Pet Shop Dapp Running On An Amazon Ec2 Instance

EC2 micro instance. This can be procuredf from your AWS account. Youll need to be able to ssh into the EC2 micro instance. Youll need toinstall Node.js > 6.0.0 to the micro instance. I installed Node.js 6.11.2. You can install Node.js by following these Next, youre going to install TestRPC and Truffle. TestRPC is the test environment that makes it much easier to run your own testnet. We have another blog posts that describes how to create a CustomGenesis.json block for testing here. For this tutorial, save yourself the trouble. Use TestRPC. After you ssh into the micro instance, type the first command below, which will install TestRPC. Next, type the second command, which will install the Truffle development framework into your current directory. Next, were going to pull the completed Pet Shop demo from my Github repo by typing the first command into the ssh terminal. Well then run npm update in the same terminal to update our node_modules. git clone After the npm update is performed, go into the node_modules directory to ensure that the modules are populated. Now, we need to start up the TestRPC Ethereum server. In order to do this, youll want to open another command shell, ssh into the EC2 instance, and run TestRPC. When you run TestRPC, youll want to make note of the available accounts, private keys, and mnemonics. After youve started TestRPC, it should be listening on port 8545. Next, go back to your initial ssh terminal.If youre cheap like me and youre running this on an EC2 micro instance, then youll want to increase your swap space. Otherwise, your TestRPC instance will run out of RAM during compilation of the source code. Youll want to create a 1 GB swap file. In the initial ssh terminal, type the following commands to create a permanent swap file: sudo /bin/dd Continue reading >>
