If you have it installed, it should output something like this: If instead the command returns an error, then you need to install it. If you don't have solC installed, we have a online solidity compiler available. But be aware that if the compiler is compromised, your contract is not safe. For this reason, if you want to use the online compiler we encourage you to host your own . Press control+c to exit the console (or type exit) and go back to the command line. Open the terminal and execute these commands: sudo add-apt-repository ppa:ethereum/ethereumsudo apt-get updatesudo apt-get install solcwhich solc Take note of the path given by the last line, you'll need it soon. You need brew in order to install on your mac brew tap ethereum/ethereumbrew install soliditywhich solc Take note of the path given by the last line, you'll need it soon. You need chocolatey in order to install solc. Windows is more complicated than that, you'll need to wait a bit more. If you have the SolC Solidity Compiler installed, you need now reformat by removing spaces so it fits into a string variable (there are some online tools that will do this) : git clone cpp-ethereum/buildcd cpp-ethereum/buildcmake -DJSONRPC=OFF -DMINER=OFF -DETHKEY=OFF -DSERPENT=OFF -DGUI=OFF -DTESTS=OFF -DJSCONSOLE=OFF ..make -j4 make installwhich solc Now go back to the console and type this command to install solC, replacing path/to/solc to the path that you got on the last command you did: If you now have solC installed, then congratulations, you can keep reading. If you don't, then go to our forums or subreddit and berate us on failing to make the process easier. If you have the compiler installed, you need now reformat your contract by removing line-breaks so it fits into a string variable (there are some online to Continue reading >>

Want To Get Involved With Ethereum? Heres How

Want To Get Involved With Ethereum? Heres How

Want To Get Involved With Ethereum? Heres How Looking to get involved with Ethereum but unsure of where to start? Use this reference to guide your research. Ethereum is becoming more popular as the ecosystem continually expands. More people are onboarding themselves, especially with the rising price of Ether (ETH) helping to spread the word. The problem is Ethereum has always been a bit ethereal. If youre looking to get involved with Ethereum, heres how. Learn Solidity . Solidity is a programming language used to write executable distributed code contracts ( EDCCs ). Solidity programmers will be in high demand as blockchain technology continues to disrupt markets. If youre looking for good pay and steady employment, consider learning how to code EDCCs. (And please, please learn industry standard best practices . Its integral to the security of your code and the perceived stability of the entire network.) Launch your own coin (aka an ERC20 token ). Creating your own virtual currency isnt actually as hard as it sounds. Its mostly just copying and pasting open source code. The hard part is getting your coin to have any value. Tokens are generally used as markers of membership in a DAO (decentralized autonomous organization) or as the currency that powers a specific project or Dapp (distributed application). Without a strong reason behind a tokens existence, its not likely to see any investment or adoption, and therefore will only have what value you personally put into it. Become a bug bounty hunter. Many projects, from their early stages straight through their launches, have bug bounty programs. This usually involves reviewing open source code on GitHub. If you find a bug, you are rewarded for your White-Hat efforts, usually with an amount of cryptocurrency in line with Continue reading >>

5 Ways To Make Money With Ethereum

5 Ways To Make Money With Ethereum

You are at: Home Knowledge 5 Ways To Make Money With Ethereum Ethereum is here to stay. At least for a while. And therefore manyearly adopters are looking for ways to make money with Ethereum. The cryptocurrency world is an industry that will make many millionaires and billionaires in the following years, and its your choice if you want to ride the wave and profit from this new technology. If you are a bit tech-savvy then you should probably consider starting mining Ether. Especially if you think that this digital asset will keep increasing in value for the next year or two. This is important because depending on what mining equipment you buy and how much electricity costs where you live, it can take up to 6 months to pay back your initial investment. For this to happen it is very important for the price of Ethereum to remain at its current price. Of course, if it increases then this timeframe will be even shorter! The people over at 99bitcoins have built an Ether mining profitability calculator . I highly recommend you to check it out before you purchase your equipment. This way you will know before hand if this little venture is going to be worth your time. Additionally, you will be able to predict how much moneyyou will be earning from your mining rigs every month. Its definitely a nice side income to have! Especially if the electricity costs are low where you live. Although this option may seem obvious, I thought it is a good idea to include it in this post along with some interesting facts.In 2016 alone, Ether increased in value by nearly 1.200%, and it is showing no signs of slowing down. The creation of the Enterprise Ethereum Alliance in February has added a lot of credibilityto the project and resulted in the price skyrocketingto new record highs. At the time Continue reading >>

Ethereum [caption id="attachment_114312" align="alignleft" width="300"] iStock.com/gamegfx[/caption]To fully understand what Ethereum is, you need to know a little about blockchain, a word that cryptocurrency followers have been taking for granted.The easiest way to explain blockchain is with an analogy from your daily life. If cryptocurrency is e-mail, blockchain is the Internet. At its basic level, Ethereum is a software platform based on blockchain technology. The platform allows for the building and deployment of decentralized applications.Until very recently, building blockchain applications used to require significant resources anda specialized understanding of mathematics, coding, and cryptography. But, thanks to Ethereum and its tools to build decentralized applications, previously unimagined applications can now be actively developed and deployed faster than ever before. People interested in Ethereum often ask What is Ether?" Understanding Ether is very crucial, because it is fundamental to the functioning of Ethereum.Just as all machines use some sort of fuel, so do blockchains. Ethereum uses Ether, a unique code that can beused as a way to pay for running an application or a program. Just like a slot machine requires Continue reading >>

The Hitchhikers Guide To Smart Contracts Inethereum

The Hitchhikers Guide To Smart Contracts Inethereum

The Hitchhikers Guide to Smart Contracts inEthereum Updated Oct 6th 2017, for Truffle v3.4.11 and Solidity v0.4.15. Ive been working with smart contracts for 4 years , mainly in the Bitcoin blockchain. Some projects I participated in are Proof of Existence , bitcore , and Streamium . In the past months, Ive been exploring and working with the Ethereum platform. Ive decided to compile a short guide to ease the way of future programmers learning Ethereum smart contract development. Ive divided the guide in two sections: how to get started building smart contracts in Ethereum, and a quick note on smart contract security. Getting started with Smart Contracts onEthereum This guide assumes you have a basic level of technical understanding on how cryptocurrencies and blockchains work. If you dont, I recommend skimming over Andreas Antonopoulos Mastering Bitcoin book , Consensys Just Enough Bitcoin for Ethereum guide , or at least watching this short video by Scott Driscoll . To continue ahead you should know what a public and private key are, why a blockchain needs miners, how decentralized consensus is reached, what a transaction is, and the concepts of transaction scripting and smart contracts. Two other important and related concepts youll need to understand before working with Ethereum are the Ethereum Virtual Machine and gas. Ethereum was designed as a smart contract platform. Its origin is actually linked to a critique made by Vitalik Buterin on bitcoin as a very limited smart contract platform. The Ethereum Virtual Machine (EVM) is where smart contracts run in Ethereum. It provides a more expressive and complete language than bitcoin for scripting. In fact, it is a Turing Complete programming language. A good metaphor is that the EVM is a distributed global computer wh Continue reading >>

Running A Masternode Is An Excellent Way To Earn Passive Income

Running A Masternode Is An Excellent Way To Earn Passive Income

Running a Masternode Is an Excellent Way to Earn Passive Income Running a Masternode Is an Excellent Way to Earn Passive Income When it comes to making money with cryptocurrency, there are many ways to do it. Diversifying into altcoins, investing in ICOs, or just daytrading in general are all valid approaches. Some coins offer a masternode system which automatically rewards users with small amounts of coins forlocking up a certain amount of currency and providing valuable services to the network. Although this may sound less than appealing, it is a good way to make money, especially with new currencies. Setting up a masternode is not something one can do for just any currency these days. In fact, none of the major currencies except for Dash support this business model right now. That situation wont change overnight either, as there is usually no incentive for running a network node these days. Especially in the world of Bitcoin and most popular altcoins, there is no reason to have masternodes. To put this into perspective, most currencies providing masternode services focus on privacy and anonymity. Dash is perhaps the best-known currency in this regard, as ithas been running a masternode incentive system for quite some time now. It does require users to lock up a lot of coins in a wallet and not spend theirbalances for as long as they wishto operate the node. All Dash masternodes provide InstantSend features for the entire network, which enables anonymous transactions. One could argue Monero would have a use for masternodes in this regard, but that is not the case. Most of the Dash clones out there and there are plenty of those offer a masternode system which provides similar features to users of theparticular network. Some of the more recent coins coming to mind incl Continue reading >>

What Is A Masternode?

What Is A Masternode?

What Is A Masternode And How Is It Useful For Cryptocoin Investors By: Sudhir Khatwani In: Blockchain Last Updated: In the cryptosphere, they say only those who can finely analyze the market or are day traders can make money.But thats not true!! In the cryptosphere, there are several ways by which you can make profits and earn a handsome amount of money.And the best thing is that you can choose the best way that works for you and can accordingly adjust your reward/risk ratio. One such way of earning in cryptosphere is by running a masternode, but before I tell you how to do that it is imperative that you first understand what a masternode is. Masternode is simply a cryptocurrency full node or computer wallet that keeps the full copy of the blockchain in real-time, just like your have Bitcoin full nodes and is always up & running. <br /> Can't load widget<br /> But masternodes are considerably different in their functionality than normal nodes. They are different because they perform several other functions apart from just keeping the full blockchain and relaying blocks/transactions as a full node does in Bitcoin /Litcoin. Some of the special functions that these nodes perform are: Enable budgeting and treasury system in cryptos These masternodes are not standalone but they are always communicating with other such nodes to make a decentralized network and are often referred in short form as MN. Note: Mostly the masternodes perform the tasks that I have listed above but it can slightly vary from cryptocurrency to cryptocurrency depending upon how masternodes have been implemented. But more or less they perform these functions in a cryptocurrency. Just like full nodes in a cryptocurrency, masternodes can be run by anyone. However, there is an e Continue reading >>

Installing And Running A Node | Ethereum Frontier Guide

Installing And Running A Node | Ethereum Frontier Guide

The Frontier tool is called Geth (the old english third person singular conjugation of "to go". Quite appropriate given geth is written in Go . Geth is a multipurpose command line tool that runs a full Ethereum node implemented in Go. It offers three interfaces: the command line subcommands and options , a Json-rpc server and an interactive console. In order to install Geth, open a command line or terminal tool (if you are unsure how to do this, consider waiting for a more user friendly release) and paste the command below: bash <(curl This script will detect your OS and will attempt to install the ethereum CLI. For more options including package managers, check the OS-specific subsections. For the purposes of this guide, we will focus on the interactive console, a JavaScript environment. The history of the console is persisted between sessions, providing for a powerful and flexible way of using the client. You can navigate your command history by using the up and down arrow keys, like a standard command line. To get started Type the code below on your terminal Once geth is fully started, you should see a > prompt, letting you know the console is ready. To exit, type exit at the prompt and hit [enter]. Output from the console can be logged or redirected: Using standard tools, the log can be monitored in a separate window: Alternatively, you can also run one terminal with the interactive console and a second one with the logging output directly. In the second terminal type tty. The output will be something like /dev/pts/13 In your main terminal, type: geth console 2>> /dev/pts/13 This will allow you to monitor your node without cluttering the interactive console.

Getting Up To Speed Onethereum

Getting Up To Speed Onethereum

Go from zero to without all the nonsense. You want to have a deep working understanding of Ethereum and the related ecosystem. You understand the concept of a blockchain and how Bitcoin uses it to create a trustless digital currency. No? Watch this short video or watch this long video . Hint, you should probably watch the long one. Youre a professional software engineer. Seriously, I mean, nontrivial amounts of real-world software engineering experience. Understanding systems/architecture/math is a learning efficiency multiplier. Like a week of your free time. I told you were skipping the nonsense. You understand the basic concept of a merkle tree and how it can be used to quickly verify information correctness. Note: you dont need to read the whitepapers, but you need to understand them. But it turns out that reading them is the fastest way to understand them. I recommend reading the entirety of this post, absorbing the contents at a high level, and then diving into each link individually, over the course of a few days. Youll be surprised at how little of this technology is magic (read: none of it), despite the severe case of buzzword-itis the ecosystem has. Everyone is building off of the shoulders of giants; if you make a living as a professional software engineer you have the ability to understand all of these projects and technologies at a deep level. Just dont get distracted by the bullshit. Ethereum is a distributed computer; each node in the network executes some bytecode (hint: Smart Contracts), and then stores the resulting state in a blockchain. Due to the properties of the blockchain representing application state, this results in applications that run exactly as programmed without any possibility of downtime, censorship, fraud or third party interference.

Jonas Schnelli Wants You To Run A Bitcoin Full Node

Jonas Schnelli Wants You To Run A Bitcoin Full Node

Jonas Schnelli Wants You to Run a Bitcoin Full Node Jan 12, 2018 at 07:00 UTC|UpdatedJan 12, 2018 at 22:48 UTC That's the maximum load some personal laptops will store. It's also roughly the amount of space the bitcoin blockchain currently requires. These bloating storage requirements are a longstanding problem for the community's efforts to keep bitcoin decentralized. But Bitcoin Core contributor and maintainer Jonas Schnelli has spent the past few years trying to make full nodes easier to run for a wider audience despite this huge data cost - and in turn, make bitcoin more resistant to centralization. With so much information to download, setting up a bitcoin full node currently takes days or even weeks. This issue was at the heart of bitcoin's years-long scaling debate. While increasing transaction capacity by raising the block size limit might have eased the network's steadily rising transaction fees, it also would have disqualified more users from running bitcoin's core infrastructure. And even though the block size held steady, the pressures favoring centralization remain, because of the storage space and time it takes to set up a full node. Yet, developers argue that running a full node is the best way to use bitcoin (some even going as far as to claim that without a full node to validate bitcoin transactions themselves, users are just wasting their time on cryptocurrency). In this way, users take full advantage of all bitcoin's benefits, including censorship-resistance and the minimization of trust in third parties. "It's very important to run bitcoin full nodes. It's the main or at least a significant reason to use bitcoin," Schnelli told CoinDesk. "If we throw that away we lose one of the more interesting parts of bitcoin." Schnelli's particular focus is on m Continue reading >>

The Ethereum Project's logo, first used in 2014 Ethereum is an open-source , public, blockchain -based distributed computing platform featuring smart contract (scripting) functionality. [2] It provides a decentralized Turing-complete virtual machine , the Ethereum Virtual Machine (EVM), which can execute scripts using an international network of public nodes. Ethereum also provides a cryptocurrency token called "ether", which can be transferred between accounts and used to compensate participant nodes for computations performed. [3] "Gas", an internal transaction pricing mechanism, is used to mitigate spam and allocate resources on the network.

Stop Building New Rigs! It Is Not Worth It! Please Read Before You Start Mining!

Stop Building New Rigs! It Is Not Worth It! Please Read Before You Start Mining!

My English knowledge is average so please sorry for grammatical mistakes. Thank you Proof that if you buy RIG just to mine ETH is not a good idea: There are a lot of threads where people are saying that the moment to start mining is lost...But people are still begin mining! First of all you do not understand what means difficulty and what means return of investment. I begin mining one year ago... And it was already to late for me to get in. Why? Because the amount of Ether produced in all this time by me is lower, than if with the same amount of money I invested in production, I would buy directly Ether's! Yes! And I started 1 year ago. Difficulty grew up very fast and amount produced every day become lower and lower! I don't tell you problems with heat in the summer and freezing Rig's ... So if I would buy Ethers at 10$ (at this price I can buy exactly amount of Ether I produced in one Year) one year ago I would sell now at 4 times profit! But there was moments when Ether fall down to 6-7$ (At this price I would buy much more Ethers than I produced in 1 year) which I would sell at 7-8 times profit! Or I would sell now just an amount to recover investment and wait for Ether to go to the moon! Big Idea is that now is the same. Just make a calculation. With a computer with 5 rx480's you will produce about 0.27 per day, that's 8 Ether's/month (if your computer will work 100% of time). But this you will produce in first month, in next months amount will be lower and lower! In just couple of months amount of Ether produced can be 4 Ether's/month. For Example as evidence of that in November-December 2016 you would produce 150-200 % more than know.... You can check the difficulty graph for evidence... Also there is POS coming...which can happen this year! So you will never re Continue reading >>

You Really Should Run A Bitcoin Full Node: Here's Why

You Really Should Run A Bitcoin Full Node: Here's Why

You Really Should Run a Bitcoin Full Node: Here's Why On day one of the 2017 MIT Bitcoin Expo , Sia Co-Founder David Vorick , who has contributed to Bitcoin Core , gave a presentation on the important role played by full nodes in digital currency networks. In his view, economically relevant full nodes are the ones that have voting power (for lack of a better term) in attempted hard-forking changes to the rules of Bitcoin. Early in his talk, Vorick focused on the general role played by full nodes on the network. Full nodes validate transactions on the Bitcoin network, he stated. Bitcoin has this longest-chain rule where the chain with the most work in it is the one that everybody follows, except this chain also has to follow all of the rules that the network has. The full nodes are the ones [that] check that the chain follows the rules, and if a chain doesnt follow the rules, it doesnt matter how much hashrate is behind it, that chain is ignored. According to Vorick, of all the different types of Bitcoin users, full nodes are the only ones that check that the rules are followed. Those who run an SPV node or use some sort of web wallet are putting their trust in others to verify that certain rules are being followed correctly on the most-work chain. Theyre faster, Vorick said in terms of SPV nodes. They download all the headers. They make sure that they are on the chain with the most work, but they dont actually check that the chain with the most work is legal or is valid. Vorick went on to state that SPV nodes are essentially betting that the rest of the network will sufficiently handle the validation process for them. SPV nodes just blindly have faith in the broader network to do this process that makes sure that the longest chain is always valid, Vorick continued. The Continue reading >>

Ethereum Now Has Three Times More Nodes Than Bitcoin

Ethereum Now Has Three Times More Nodes Than Bitcoin

Ethereum Now Has Three Times More Nodes Than Bitcoin The ethereum network has nearly 25,000 reachable nodes, spread across the globe, less than two years after its launch, while bitcoin currently has only around 7,000 nodes that verify the network. Ethereum is now the most decentralized public blockchain with the highest number of nodes image source ethernodes. The bitcoin community has been engaging in a long standing debate on scalability with node numbers being the primary point of contention regarding the available options to increase capacity. Small blockers argue that an increase of on-chain capacity adds resource requirements on nodes, thus increases costs, which leads to a decreased number of individuals who are willing to run a node. They then extrapolate to sometime in the next century to say that as on-chain transactions are kept forever, nodes will eventually have to be in massive data centers, thus decreasing their numbers considerably to perhaps 10 or 20. On-chain transactions, therefore, should be kept limited, argue small blockers. Big blockers say that technology grows exponentially with resource requirements to run a node being negligible, therefore on-chain capacity should operate above demand so that it is useful to the most amount of people. They further argue that as on-chain demand increases, so do the number of individuals or businesses who wish to or have to run a node, thus increasing the number of nodes. The small blockers proposition, they say, will either keep node numbers static or will cause them to decrease gradually as network utility is lowered due to lack of capacity. As for the very long term, sharding is a solution which can lower resource requirements for nodes, they say, allowing them to always be easily affordable for businesses, Continue reading >>
