Keep in mind that when trading CFDs your capital is at risk. Lately there has been a lot of talk about the hottestaltcoin in the community Ethereum. Ethereum is a cryptocurrency and a blockchain platform with smart contract functionality. Its basically a decentralized platform for developers to build apps on top of and it was invented by Vitalik Buterin in 2013. Ethereum can be used to codify, decentralized, secure and trade just about anything: voting, domain names, financial exchanges, crowdfunding, company governance, contracts and agreements of most kind, intellectual property. Well, Ether is the currency of the Etherium platform. Etherwill be required by anyone wishing to build upon oruse the Ethereum platform. Just like BItcoin, Ether can be traded around the web and mined. In a second Ill show you exactly where you can buy it. Most people use the term Ethereum to refer to the currency instead of Ether and thats why it can get so confusing. The total supply of ether and its rate of issuance was decided by the donations gathered on the 2014 presale of the currency. The results were roughly: 60 million ether created to contributors of the presale 12 Million (20% of the above) were created to the development fund, most of it going to early contributors and developers and the remaining to the Ethereum Foundation 5 ethers are created every block (roughly 15-17 seconds) to the miner of the block 2-3 ethers are sometimes sent to another miner if they were also able to find a solution but his block wasnt included (called uncle/aunt reward) The founders of Ethereum state that Ether is not a currency as much Continue reading >>

How To Transfer Bitcoin, Ether & More From Coinbase To Binance Smartphones :: Gadget Hacks

How To Transfer Bitcoin, Ether & More From Coinbase To Binance Smartphones :: Gadget Hacks

The most convenient way for US users to buy Ripple (XRP) or Stellar (XRM) is through Binance . However, you can't deposit money directly into this app, but you can deposit cryptocurrency like ether or bitcoins to buy other alt-coins. The easiest way to do that is by using Coinbase , the most popular cryptocurrency app. Despite some delays in transaction times and freezes on new registrations, this combination of Coinbase and Binance has proven to be quite dependable. Binance in particular, has the added benefit of letting you trade with both Bitcoin (BTC) and Ethereum (ETH) as base currencies, which means you have more options not only in trading, but also in terms of choosing between digital coins based on faster transaction times and lower network fees. Don't Miss: How to Install the Binance App on Your iPhone You can transfer Bitcoin (BTC), Bitcoin Cash (BCH), Ethereum (ETH), or Litecoin (LTC) from Coinbase to Binance, but I'll demonstrate using LTC. The bulk of the process will be the same regardless of which coin you choose, but note that if you transfer BCH or LTC from Coinbase, you'll have to convert them into BTC, ETH, or Binance Coin (BNB) to trade the coins on Binance. Step 1: Find Your Source Wallet in Coinbase To start, you'll need to select the wallet that you'll be transferring coins out of. There are three ways to access your wallet in Coinbase either tap on the coin's chart, select "Accounts" at the bottom of the screen, or tap "Your Accounts" above the coin's chart. Tapping on a coin's chart will take you directly to its landing page, complete with a graph showing its price movements this week. From there, open that coin's specific wallet page by selecting the "LTC Wallet" tab (for example) right below the "Buy" and "Sell" buttons. Tapping on "Accounts Continue reading >>

Ethereum "gas" - How It Works

Understanding how gas works is crucial for Ethereum users interested in participating in ICOs, using smart contracts, and even making simple transfers between wallets. In this post, I hope to explain what gas is and how it works. Skip to the end for a simple summary of things. To start off, we need to understand some basics about the Ethereum Virtual Machine. The Ethereum Virtual Machine (EVM) is a major part of the Ethereum ecosystem, but I'll be heavily glossing over this so we can focus on how it relates to gas. In short, the EVM is an environment where arbitrary code of smart contracts and other operations can be executed. Every node in the Ethereum network executes operations within the EVM to ensure redundantly correct execution and relies on consensus to agree on the answer. All transactions, from simple transfers to ICO smart contracts, require some amount of operations to perform. Each of these operations has an associated cost in gas. Thus, simple transactions like transfers will require less gas to perform than more intense smart contracts. For example, a simple operation like if(var > 1) may cost 1 gas, but a more complex operation to store a variable could cost 100 gas. The cumulative sum of all the operations is the total gas cost for the transaction. When on a site like MyEtherWallet, you're going to see a field called Gas Limit. This corresponds the the MAXIMUM amount of gas you are willing to spend on the transaction. Different types of transactions will require different amounts of gas to complete Providing too little gas will result in a failed transaction, the fees are kept by the miner Extra, unspent gas is refunded automatically What happens if I specify too little gas? Your transaction will start to be executed, but will eventually run out of gas Continue reading >>

Eidoo Your Blockchain Asset Experience Ethereum

Eidoo Your Blockchain Asset Experience Ethereum

Eidoo is a blockchain-to-human interface simplifying the interaction between the Ethereum and Bitcoin blockchains and its users. We are proposing Eidoo as a new blockchain asset experience providing an easy and secure way to buy, transfer, spend, and exchange cryptocurrencies without relying on any central authority. Ethereum is revolutionizing the blockchain concept by introducing the possibility to write and certify smart contracts on each single node of the network. This design provides flexibility to blockchain uses that go far beyond the simple transactions of Ether (ETH, or the main digital currency that runs on the Ethereum blockchain). In addition to the ability to execute and certify smart contracts, the Ethereum blockchain offers the possibility to create and manage new assets. These assets are actually smart contracts based on the standard known as ERC 20. Presently, it is not possible to assign unique names and symbols to Ethereum tokens: tokens can be created havingthe same name or symbol to other pre-existing tokens. This is a considerable problem for a simple and secure use of digital currency wallets because while each token has a different Ethereum address, the human eye is unable to handle complex alphanumeric codes with ease, hence each token must be recognized with a name,an abbreviation, and a symbol Eidoo implements a special index that will group together tokens issued by companies having both legal and/or informal statute, and legitimate tokens. Tokens having names/abbreviations/symbols equal to those in this special index are labeled by Eidoo as untrusted in order to avoid scams and misunderstandings. Eidoo is, therefore and first of all, a multicurrency wallet designed for the mobile world, a single integrated environment that manages all toke Continue reading >>

Erc20 Token Standard

Erc20 Token Standard

The ERC20 token standard describes the functions and events that an Ethereum token contract has to implement. Following is an interface contract declaring the required functions and events to meet the ERC20 standard: 1 // 2 contract ERC20 { 3 function totalSupply() constant returns (uint totalSupply); 4 function balanceOf(address _owner) constant returns (uint balance); 5 function transfer(address _to, uint _value) returns (bool success); 6 function transferFrom(address _from, address _to, uint _value) returns (bool success); 7 function approve(address _spender, uint _value) returns (bool success); 8 function allowance(address _owner, address _spender) constant returns (uint remaining); 9 event Transfer(address indexed _from, address indexed _to, uint _value);10 event Approval(address indexed _owner, address indexed _spender, uint _value);11 } Most of the major tokens on the Ethereum blockchain are ERC20-compliant. The GNT Golem Network Token is only partially-ERC20-compliant as it does not implement the approve(...), allowance(..) and transferFrom(...) functions, and the Approval(...) event. Some of the tokens include further information describing the token contract: 1 string public constant name = "Token Name";2 string public constant symbol = "SYM";3 uint8 public constant decimals = 18; // 18 is the most common number of decimal places Following is a fragment of a token contract to demonstrate how a token contract maintains the token balance of Ethereum accounts: 1 contract TokenContractFragment { 2 3 // Balances for each account 4 mapping(address => uint256) balances; 5 6 // Owner of account approves the transfer of an amount to another account 7 mapping(address => mapping (address => uint256)) allowed; 8 9 // What is the balance of a particular account?10 functio Continue reading >>

Raiden Network - Fast, Cheap, Scalable Token Transfers For Ethereum

Raiden Network - Fast, Cheap, Scalable Token Transfers For Ethereum

Fast, cheap, scalable token transfers for Ethereum The Raiden Network is an off-chain scaling solution, enabling near-instant, low-fee and scalable payments. Its complementary to the Ethereum blockchain and works with any ERC20 compatible token. The Raiden project is work in progress . Its goal is to research state channel technology, define protocols and develop reference implementations. Scales linearly with the number of participants Transfers can be confirmed within a subsecond Individual transfers dont show up in the global shared ledger Works with any token that follows Ethereums standardized token API (ERC20) Transfer fees can be orders of magnitude lower than on the blockchain Low transaction fees allow to efficiently transfer tiny values The Raiden Network is an infrastructure layer on top of the Ethereum blockchain. While the basic idea is simple, the underlying protocol is quite complex and the implementation non-trivial. Nonetheless the technicalities can be abstracted away, such that developers can interface with a rather simple API to build scalable decentralized applications based on the Raiden. Blockchains dont scale well because there needs to be global consensus on the order and outcome of all transfers. Every participant needs to learn about all updates to the shared ledger. Hardware and bandwidth constraints set a limit on the number of updates per second that can be shared in a decentralized network. The basic idea of the Raiden Network is to avoid the blockchain consensus bottleneck. This is done by leveraging a network of payment channels which allow to securely transfer value off-chain, i.e without involving the blockchain for every transfer. To learn more, read the Raiden Network 101 , take a look at the current specification or check out the c Continue reading >>

What Is An Ethereum Token: The Ultimate Beginners Guide

What Is An Ethereum Token: The Ultimate Beginners Guide

What is An Ethereum Token: The Ultimate Beginners Guide Angel Investors, Startups & Blockchain developers... To a beginner, the entire concept of Ethereum and Ethereum token can get very confusing very fast. The idea that Ethereum not only has its own currency (Ether) but also has tokens on top of that which can act as currency themselves, can be a little mind-boggling. Before we even begin understanding what Ethereum tokens are all about, its important to grasp some basic concepts. The entire Ethereum network is a giant mass of nodes (computers) connected to one another. In fact, the entire network can be visualized as a single entity called the Ethereum Virtual Machine or EVM for short. All the transactions that have happened and will ever happen in this network are automatically updated and recorded in an open and distributed ledger. So what is the advantage of this? Before we explain that it is important to know what a smart contract is. Smart contracts are how things get done in the Ethereum ecosystem. When someone wants to get a particular task done in Ethereum they initiate a smart contract with one or more people. Smart contracts are a series of instructions, written using the programming language solidity , which work on the basis of the IFTTT logic aka the IF-THIS-THEN-THAT logic. Basically, if the first set of instructions are done then execute the next function and after that the next and keep on repeating until you reach the end of the contract. The best way to understand that is by imagining a vending machine. Each and every step that you take acts like a trigger for the next step to execute itself. It is kinda like the domino effect. So, lets examine the steps that you will take while interacting with the vending machine: Step 1: You give the vending mac Continue reading >>

Erc865: Pay Transfers In Tokens Instead Of Gas, In One Transaction #865

Erc865: Pay Transfers In Tokens Instead Of Gas, In One Transaction #865

Wouldn't a way simpler solution be to have contracts set gasprice & startgas so miners are allowed to take gas from the contracts balance? Then nodes/miners would use limited gas per transaction to determine if these transactions are mineable at all (gas price is high enough) and warrant to be re-broadcast over the network. In other words, nodes/miners are executing the code of transactions (where the sender doesn't have enough funds themselves), and which contain 'gasprice & startgas'-opcodes. Contracts can then convert tokens to gas themselves. Basically wallets would allow users to set gasprice & startgas in the used token, and the contract converts that to ETH. Or if the contract is rather predictable in gas usage make it even easier for users by allowing users to only set gasprice. Right, we need to pass it, but it doesn't have to be encoded. Good catch Letting the first person to get a transaction in harvest the fee Using msg.gas price makes sense, but we should probably come up with another name, since "gas price" is usually in wei. Concerning the naming of the methods, what would you think of prefixing the methods with "delegated", instead of suffixing with "presign", for insisting on the fact that someone else is bringing the transaction on chain? Concerning the direction, we probably want to open a pull request on Open Zeppelin (cc @spalladino ). Would it work with the constraints of your licence? I have been working on this idea for a side-project, the pay-protocol . This feature is something that can be achieved in a layer 2 protocol rather than adding this functionality to every token contract. Which also has the ability that every token currently deployed could use it, just by having people that want to use this create a ERC20 allowance to the PayProtocol Continue reading >>

Coinbase Bug Allows User To Transfer Unlimited Ethereum To Wallet

Coinbase Bug Allows User To Transfer Unlimited Ethereum To Wallet

Coinbase Bug allows User to Transfer Unlimited Ethereum to Wallet Coinbase, one of the worlds most popular cryptocurrency exchanges, has had a nasty bug lurking in its system that would allow users to collect unlimited ether through a few simple steps. Thanks to a bug report, however, the company avoided disaster. A Dutch FinTech company, VI Company , publicly disclosed a Coinbase bug on March 20. According to the vulnerability report, a custom built smart contract with a string of digital wallets could be manipulated into tricking Coinbase algorithms that a transfer had taken place. The Ethereum blockchain is deemed in some ways superior to Bitcoin s due to its usage of smart contracts. For non-specialists, a smart contract is a set of if/then conditions regulating the transfer of an underlying asset/fund/security. To build familiarity with smart contracts amongst its employees, VI Company initiated a unique Christmas present in 2017. The smart contract would reward employees with a small amount of ether as means of festive Bonus on Christmas. However, the company noticed a bug. In a smart contract, in case one of the internal transactions of the contract failed, all the transactions would be reversed, which is how the smart contract should work. But employees with knowledge of the project found out that Coinbases internal accounts didnt register the reversal. Hence, the Coinbase software thought that wallet had been credited with additional ether, but in reality, the wallet would have no deposit made. A screenshot of its transactions was made available to the public by VI Company, which also outlined the steps which allowed for an unlimited amount of ETH to be credited : Setup a smart contract with a few valid Coinbase wallets and [one] final faulty wallet, Transfer Continue reading >>

Un's World Food Programme Builds On Ethereum Blockchain Cash Transfers

Un's World Food Programme Builds On Ethereum Blockchain Cash Transfers

Join our community of 10 000 traders on Hacked.com for just $39 per month. The United Nations World Food Programme is expanding its Ethereum-based blockchain payments system to avoid the transfer fees incurred via the traditional banking system. Over a year ago in January 2017, the World Food Programme (WFP) successfully tested Building Blocks, an early experiment that enabled the transfer of WFP food and cash on a public Ethereum blockchain through a smartphone app, to vulnerable families in Pakistan. Blockchain technology, most famously associated with the crypto-currency Bitcoin, offers unique opportunities for humanitarian agencies to provide the best-possible assistance to vulnerable people around the world, the WFP said at the time. Within months, the WFP ran a full pilot in the Jordanian refugee camp of Azraq to successfully facilitate cash transfers for over 10,000 Syrian refugees on its blockchain payments platform. The pilot alone is said to save the agency $150,000 a month while eliminating a staggering 98% of bank-related transfer fees, according to Munich WFP innovation lab chief Bernhard Kowatsch. Beyond money transfers, the implementation of blockchain technology enabled Syrian refugees to buy food from local retailers using a biometric scan of their eye wherein each transaction is recorded on a blockchain. The use of cash, bank cards or paper vouchers is rendered obsolete as refugees neednt share any sensitive data with banks or mobile operators. Instead, refugees benefit from greater security and privacy through an immutable, secure blockchain. Now, the UN agency feeding over 100 million people across 80 countries is expanding its Ethereum-based blockchain platform after estimating savings of millions of dollars in bank transfer fees by utilizing decen Continue reading >>
