What Is Gas? Gas & Transaction Fees | Myetherwallet Help & Support

When you hear gas, the person is either talking about: The total cost of a transaction (the "TX fee") is the Gas Limit * Gas Price. Typically, if someone just says "Gas", they are talking about the "Gas Limit". You can think of the gas limit like the amount of liters/gallons/units of gas for a car. You can think of the gas price as the cost of that liter/gallon/unit of gas. With a car, it's $2.50 (price) per gallon (unit). With Ethereum, it's 20 GWEI (price) per gas (unit). 21000 units of gas at 20 GWEI = 0.00042 ETH. Therefore, the total TX fee will be 0.00042 Ether. Sending tokens will typically take ~50000 gas to ~100000 gas, so the total TX fee increases to 0.001 ETH - 0.002 ETH. You can use our tool to calculate GWEI <-> WEI <-> USD here , which can be helpful when you want to know your TX fee in ETH, rather than GWEI. The gas limit is called the limit because it's the maximum amount of units of gas you are willing to spend on a transaction. This avoids situations where there is an error somewhere in the contract, and you spend 1 ETH....10 ETH....1000 ETH..... going in circles but arriving no where. However, the units of gas necessary for a transaction are already defined by how much code is executed on the blockchain. If you do not want to spend as much on gas, lowering the gas limit won't help much. You must include enough gas to cover the computational resources you use or your transaction will fail due to an Out of Gas Error. All unused gas is refunded to you at the end of a transaction. So if you go to MyEtherWallet, send 1 ETH to our donation address ( ? ), and use a gas limit of 400000 you will receive 400000 - 21000* back. However, if you were sending 1 ETH to a contract and your transaction to the contract fails (say, the Token Creation Period is already Continue reading >>

Ethereum Transaction Fee: Can Ethereum Gas Price Growth Threaten The Future Of Ethereum?

Ethereum Transaction Fee: Can Ethereum Gas Price Growth Threaten The Future Of Ethereum?

Ethereum Transaction Fee: Can Ethereum gas price growth threaten the future of Ethereum? One of the main functions of cryptocurrencies is the low cost of transactions. But what happens if the price of gas price, transaction fee, rises? Can it threaten the Ethereums future? Decentralized apps depend on Ethereum Blockchain and they need gas for transactions.Gas price has risen 100 times in year 2017 in line with the speculative growth in the price of ETH token. Ethereums blockchain now serves speculators at the expense of key users. With rising competition from Cardano, NEO, Qtum, and other platforms, Ethereum may lose its appeal to key users. Scalability issues and growing competition suggest that ETH may be overpriced at more than $1,000. Ethereum is the most popular platform to create decentralized applications using blockchain Ethereum is the most popular platform to create decentralized applications using blockchain (DAPPs). Ethereums tokens called Ether ((ETH)) are almost as popular as bitcoin (BTC) and they are traded in most of the cryptocurrency exchanges. Ethereum positions itself as a decentralized global computer to run smart contracts. Anyone with coding skills can create an application and run it on Ethereum Virtual Machine (EVM). Using Ethereum platform and EVM is similar to renting a car. Ethereum charges you for each line of code so that each line of code costs some gas. Thus, users need gas to run their applications on the Ethereum computer. Gas cannot be bought using fiat currency, it can only be bought using Ether token. Ethereum platform no longer serves the purpose it was created for? According to Seekingalpha contributor,Aydar Mannanov, despite positioning as a global decentralized computer and a platform to run DAPPs, the Ethereum platform no long Continue reading >>

Ether - How Are Ethereum Transaction Costs Calculated? - Ethereum Stack Exchange

Ether - How Are Ethereum Transaction Costs Calculated? - Ethereum Stack Exchange

How are Ethereum transaction costs calculated? I'm in the process of learning blockchain technology for a client of mine. I understand the concept of "gas" in computational costs. We are looking at creating a crypto-currency as an alternative to using a traditional payment platform for a closed loop solution. I want to get a feel for the "transaction cost" associated with a simple payment transaction using the ethereum network.I find the calculation method not totally clear. Can anyone help? is the cost of a simple transaction the same 21,000 for sending any number of ethers? the same for sending 1 ether as for sending 500 ether? brosen Jul 22 '17 at 22:30 Simple transaction that transfers value but have no additional data and not triggers any EVM code (the recipient is not a smart contract) consumes exactly 21000 units of gas. You just need to know the gas price to calculate the cost of the transaction. The default gas price was 20 Gwei (20 * 10-9 ETH), but it is recommended to use lower value now. Check out ETH Gas Station service for up-to-date statistics about gas price. You can also optimize costs by sending multiple payments in a single transaction, using a simple smart contract. Not going into the details, a single payment within such transaction will cost you ~10000 units of gas. How would you send multiple payments in a single transaction, using simple transactions. I know this is easily done from a smart contract, but have not seen any code for combined simple transactions. BokkyPooBah Jun 10 '16 at 8:29 @BokkyPooBah, you have to use a contract for this, there is not other option. Pawe Bylica Jun 8 '17 at 10:13 How can the price of sending via a contract be constant (10000 units)? Each send instruction will consume some gas so it should go linearly with the n Continue reading >>

Calculating Costs In Ethereum Contracts

Calculating Costs In Ethereum Contracts

Thinking, coding, and explaining Ethereum and blockchain technologies. GAS PRICE PSA (20170823): The median gas price at the time of writing this article was 28 Gwei, and continues to be in the realm of 20 Gwei. This is far greater than the typical average and safe-low found on EthGasStation (4 and 0.5 Gwei respectively). The median is so high because of bad gas-price defaults found in many wallets. I highly recommend using EthGasStations average gas-price or lower in order to not pay high fees and to help drive down the market rate for gas-price. UPDATE (2017096): I ported the Google Spreadsheet of OPCODES to a github repo . This repo will be maintained and updated as the yellow paper evolves. What are users storing when they hold Ether? In one sense, they are storing the ability to perform computation on the Ethereum network. This computation is done in a decentralized fashion: A miner executes the computation associated with each transaction being included in a block, resulting in an updated state. Upon successfully mining a block, a miner broadcasts the block to the network. Each of the other miners and non-mining nodes verify the validity of the transactional computation and resulting state change before accepting the block as valid, incorporating the block into their copy of the blockchain, and moving on to the next block. You may have noticed that there is incredible amount of redundancy for every bit of computation on the network. Namely, each node verifies the results of each transaction read: every node runs all of the computation. Ive been researching Ethereum and other blockchain application platforms for a long time now, and rarely, if ever, do people outright say this. Once you get into the more technical side of things, it becomes an obvious feature of t Continue reading >>

Ethereum Gas For Dummies

Ethereum Gas For Dummies

Ive been trying to figure out what Gas means in Ethereum. There is lots of information out there but I will add to it by describing what I found in my own words. Gas is just a unit of currency, like a token. It is used to set a price on different types of code execution inside the Ethereum Virtual Machine (EVM). For example, saving a variable cost 100 gas; executing an IF statement cost 1 gas. There is a list of how much gas things cost here . In a typical transaction you would say something like method.sendTransaction({from:eth.accounts[0], gas:300000}) The gas part of that statement means that you are willing to spend up to 300,000 of these gas tokens in executing this method. Now, there is another, optional, parameter in that statement, which is gasprice. This is the price in Wei that you are willing to pay for each gas token. If gasprice is not specified, then a default value is used. At the moment that value is 10 szabo, or 0.00001 Ether. Contracts on the Ethereum blockchain are of varying sizes and complexity. Therefore, a miner who is investing their computing power executing a method (a part of a contract) needs to be rewarded according to how much of that power they need to use. By inserting an amount of gas and a gasprice, you are signalling to the miner how much reward they can reap from running your code. This is fundamentally different to the Bitcoin blockchain, where the vast majority of code executions are identical (transferring bitcoin from one wallet to another) and therefore miners can predict how much it will cost them to execute every transaction in a block. So, going back to our example, when you send in the above transaction, the paying account (eth.accounts[0]) is deducted 300,000 * 0.00001 ETH, i.e. 3 ETH, and that value is sent in with the met Continue reading >>

Guide To Ethereum: What Is Gas, Gas Limit And Gas Price?

Guide to Ethereum: What is Gas, Gas Limit and Gas Price? Smokescreen no more By Aziz, Founder of Master the Crypto No responses Home Ethereum Guide to Ethereum: What is Gas, Gas Limit and Gas Price? This article breaks down the concept of gas, gas limit and gas price, which is a central feature of the Ethereum (ETH) Blockchain and ecosystem. If youve performed a simple transfer of Ether (ETH) from one place to another or participated in an Initial Coin Offering (ICO) , then chances are youre exposed to the concept of gas in the Ethereum network. Understanding the mechanics of gas and the associated terms gas limit and gas price is a crucial element to executing your ETH transactions. But before delving into the details of gas, its important to have a basic understanding of Ethereum. (Read more: Coins, Tokens & Altcoins: Whats the Difference? ) Ethereum is a giant network consisting of a huge number of computers connected together. This large, interconnected web of computers is called the Ethereum Virtual Network (EVN) essentially a global, supercomputer where all transactions occurring in the Ethereum network are updated and recorded into each computer. Ether (ETH) is the native currency of the Ethereum blockchain and is used as the fuel for the network. ETH is not to be confused with Ethereum Classic ; the latter is a fork of the Ethereum Blockchain. Heres a guide to understanding forks, hard forks and soft forks . A revolutionary functionality of the Ethereum blockchain was the introduction of smart contracts. Smart contracts are any contracts that have been pre-programmed with a set of definitive rules and regulations that are self-executing, without the need of any intermediaries. Therefore, with any given inputs, there will be a known output. As they say: Heres si Continue reading >>

Account Types, Gas, And Transactions

Account Types, Gas, And Transactions

code execution is triggered by transactions or messages (calls) received from other contracts. when executed- perform operations of arbitrary complexity (Turing completeness)- manipulate its own persistent storage, i.e., can have its own permanent state- can call other contracts All action on the Ethereum block chain is set in motion by transactions fired from externally owned accounts. Every time a contract account receives a transaction, its code is executed as instructed by the input parameters sent as part of the transaction. The contract code is executed by the Ethereum Virtual Machine on each node participating in the network as part of their verification of new blocks. This execution needs to be completely deterministic, its only context is the position of the block on the blockchain and all data available.The blocks on the blockchain represent units of time, the blockchain itself is a temporal dimension and represents the entire history of states at the discrete time points designated by the blocks on the chain. All ether balances and values are denominated in units of wei: 1 ether is 1e18 wei. Contracts in Ethereum should not be seen as something that should be fulfilled or complied with; rather, they are more like autonomous agents that live inside of the Ethereum execution environment, always executing a specific piece of code when poked by a message or transaction, and having direct control over their own ether balance and their own key/value store to store their permanent state. The term transaction is used in Ethereum to refer to the signed data package that stores a message to be sent from an externally owned account to another account on the blockchain. a signature identifying the sender and proving their intention to send the message via the blockchain Continue reading >>

Ethereum, Gas, Fuel, & Fees Consensys Media

A blockchain venture production studio building decentralized applications on Ethereum. Go to www.consensys.net and subscribe to our newsletter. Ethereum is a platform for decentralized and truthful applications that run on a global, peer-to-peer network without any administrators or a single point of failure. These applications have zero downtime and anyone can create them: it is permissionless innovation. The applications are truthful, immutable and always interoperate as they are coded. From this perspective, the terminology of smart contracts is reasonable in that they are the ultimate in contracts that always follow the terms set at their creation. The core of what makes this possible is effectively a World Computer. Technically called the Ethereum Virtual Machine (EVM), it includes operations for computation and data storage. A transaction represents a single session within the World Computer. It is the unit of interaction, similar to how a sentence is the unit of grammatical meaning, even though a single sentence can contain many words. Gas is the metering unit for use of the World Computer. As an analogy, electricity is metered by kilowatt hours. Using more computation and storage in Ethereum means that more gas is used. One fundamental reason for metering is that it provides an incentive for people (miners) to operate the World Computer. These miners get a fee for processing transactions, which is determined by the metering scheme: gas. Each operation in the EVM consumes gas. For example, a multiplication (MUL) consumes 5 gas and an addition (ADD) consumes 3 gas. Here is a spreadsheet of Ethereums operations and their gas consumption . Metering is different from fees and gas is different from Ether. To help clarify this, consider gas to be synonymous with fuel Continue reading >>

Neotogas - Neogas Calculator, Check Neo Balance & More!

NEO is China's first ever original and open source public chain project. NEO serves as a smart assets platform. Smart assets are the combination of smart contracts of blockchain technology and digital assets. NEO allows for smarter registration, issuance, and circulation of digital assets. NEO via technologies including P2P, dBFT, digital certificate, smart contract, superconductive trade, cross-chain operation protocol, enables people to manage smart contracts effectively, safely and legally. NEO Smart Economy is a next generation economy and trade where trade agreements are written in almost any programming language using a Smart Contract. NEO is often called "China's Ethereum" because of it's similiarities to the Etherum blockchain. GAS is a Cryptocurrency which is distributed by holding NEO in your wallet. GAS is used to fuel transactions on the NEO blockchain. With each NEO Block getting generated, GAS will be distributed to all NEO holders. NEOtoGAS has been brought to life by N1njaWTF . The aim of this NEO Community website is to provide an easy & simple to use NEO GAS Calculator, the actual NEO & GAS Market Price & other useful things. You can also check your NEO Balance, your NEOGAS balance & the unclaimed NEOGAS you currently got. I think the site is also great for new people that are interested in the NEO Blockchain, Cryptocurrency and its Community. With every new block being generated, it will distribute 8 GAS for all 100,000,000 NEO. These 8 GAS will then get divided and sent out to the NEO holders with every new block. That means, the GAS generation per day depends on the actual block generation rate, because GAS is being distributed when a new block gets generated. As you may have noticed, the GAS reward calculator shows 2 values. Below you can see what Continue reading >>

Estimated Gas Prices Rising Dramatically On Ethereum Network

Estimated Gas Prices Rising Dramatically On Ethereum Network

Estimated Gas Prices Rising Dramatically On Ethereum Network Estimated gas price on the Ethereum network has increased substantially, an issue that seems to be affecting Geth and Parity nodes. To guard against prohibitively high gas prices, users have been advised to manually lower their gas estimates. After further correspondence with Griff Green, he explained that the gas issue is related to the way in which estimated gas is calculated. "The bug is this: basically Geth sets the result of the estimateGasPrice as the 50th percentile of the gas price in the last 10 blocks," he explained. "If there were 100 txs [transactions] in each of the last 10 blocks (1000 txs in total for these 10 blocks) then Geth would order them from least to most [gas] and pick the one in the middle." "Somehow, there was a runaway reaction. The 50th percentile got really high and then because we are so centralized (more than 50 percent of txs use exchanges, MetaMask, MEW [MyEtherWallet] and none of them are checking ethgasstation.info to set their gas price manually, they all use this broken algo [algorithm]) it is stuck in." If I can put this in slightly simpler terms, the way that gas is calculated on Geth is using the median of the gas from the previous 10 blocks. This is publicly available and reproduced below: gpoblocks valueNumber of recent blocks to check for gas prices (default: 10) gpopercentile valueSuggested gas price is the given percentile of a set of recent transaction gas prices (default: 50) It's not completely clear why the 50th percentile is rising and I'm currently searching for more information on how this calculation is actually conducted under the hood. ETHNews will continue to provide coverage as the situation develops. Crypto never sleeps. That's why, on Saturday night, Continue reading >>

Go Ethereum - How To Calculate Transaction Fee? - Ethereum Stack Exchange

Go Ethereum - How To Calculate Transaction Fee? - Ethereum Stack Exchange

For calculating transaction fee (from web3), need to use gas price at that moment and multiply actually on how much gas was used eth.getTransactionReceipt("txhash").gasUsed Hopefully by the end of this explanation, you'll have a good understanding of the transaction fees that go along with Ether transactions. First of all, we have to understand what gas is (SKIP THIS IF YOU ALREADY HAVE A GOOD UNDERSTANDING OF GAS): This is actually a currency all on it's own used by the whole Ethereum network. It's used for the purposes of paying Miners for their work. Miners are people who working on "processing" the payments so-to-speak. Now... you may ask "why isn't Ether used as this currency instead?" Why does there need to be a totally different currency and complicate our life more? Well it partially has to do with how Crypto currencies are always changing in value, and if you had to code into the Ethereum network to adjust for these values, things become more complicated. So the solution was to separate the gas from the Ether and then just look at the exchange rate for Ether when deciding how much the gas will cost you to do your transaction. So now that we know what gas is, how do we use it? Well in the Ethereum network, the minimum amount of gas that is needed for a normal transaction to take place is 21000 gas. But, people have the option of putting in more gas. Now how it works is, the more gas you put, the more Miners are interested in mining your transaction, hence the time it takes for your transaction to happen is lower. But lets assume you don't care about transaction time, and currently for Ether it really doesn't take long at all even if you use the minimum amount of gas. So lets say you choose to put 21000 as your gas value. Cool. But how much does that gas cost? R Continue reading >>

What Exactly Is The Gas Limit And The Gas Price In Ethereum

What Exactly Is The Gas Limit And The Gas Price In Ethereum

What exactly is the Gas Limit and the Gas Price in Ethereum In this video we are talking about Gas! Specifically, we are deep-diving into the Gas Limit and the Gas Price and what its all about that. So, there the two things. The Limit and the Price. But where does it come from and what does it mean? Lets put out some simple explanations. Ethereum instructions basically run on gas. When you are executing a smart contract then it costs gas, not ether directly. So, if you are running a smart contract then each and every instruction costs a certain amount of gas. And that is capped by two factors, the amount you send along and a total block gas limit. Lets say you are interacting with a very simple smart contract. A function that saves an unsigned integer 256 value. pragma solidity ^0.4.19;contract A { uint b; function saveB(uint _b) public { b = _b; }} If you are copying and pasting this contract into Remix , you can run this contract. The same way you can interacting with this contract from MIST or via MetaMask from a website. Lets run saveB(5) and see what happens in the log window: There are three fields that are interesting to us: The first part is easy. The "gas" which is shown here, is the gas that we have sent along. This can be modified by the user who sends off the transaction. See here: The second part, the transaction cost, shown here in Remix, is a mix of the actual transaction cost plus the execution cost. This is a bit misleading in my opinion, but let's see. If you are sending off a transaction with a data field then the transaction has a base cost and for each byte send and additional cost attached (in gas). Looking at the Appendix of the Ethereum Yellow-Paper : Let's have a look how the transaction cost of 41642 comes together. This is our data field that Continue reading >>

Estimated Gas Doesn't Match The Actual Gas Usage. #1590

I have been super busy lately so I'm not sure I'll have time to put together a formal repro case, but factory contracts submitted with no gas seem to be the source of my troubles. contract MyFactory { function create() returns (address) { return new MyContract(); }} If I call eth_estimateGas on that, I'll get back an accurate gas estimation and can then follow-up with an eth_sendTransaction call that will succeed. However, if I just do eth_sendTransaction with no gas included (so Geth estimates the gas required internally) then the call will fail. This appears to happen anytime a transaction includes a new Foo() somewhere in the call chain. Note: the above alone may not reproduce the problem, though I suspect it will and if I have time to create a repro case that is where I'll start. Our actual repro case is much more complicated, though if you really want to dig then calling .initialize() is what fails unless you comment out the new Delegator(...) in ReputationTokenFactory.

What Is Ethereum Gas?

What Is Ethereum Gas?

Perhaps youve already faced the situation when an Ethereum app doesnt want to run, because you have no gas. But what does this term mean? Is it possible to use the application without Ethereum gas? Where to charge the app? And where to get the Ethereum gas price chart? We provide answers to these questions below. First of all, read this small but informative description: In Ethereum gas plays a role of the execution fee. Ethereum gas is used to run every operation within the ecosystem, so it is impossible to run Ethereum apps without gas. The Ethereum gas price is expressed in ether and decided by miners, so there is no fixed gas price that transactions must have. If an Ethereum miner decides that a transaction has to low gas price, her or she can refuse the transaction. If you are wondering where to take Ethereum gas, simply add ether to your account. Thus, you will make your Ethereum application run. Now, lets try to figure out the relation between EVM, dApps, and blockchain . EVM is the abbreviation of the Ethereum Virtual Machine an execution environment implemented on the blockchain. As for dApps, they represent an absolutely new kind of applications decentralized apps. These apps require Ethereum gas to work. When such application is run, the following happens: there is a network with nodes and every instruction is executed on these nodes. Since the operations are not free, you should spend a specific amount of gas units on them. The more complex the transaction is, the more gas it require. You can see a cost of every operation that a script can execute in the EVM specification. The same is about the Ethereum gas price chart, you can find it in the EVM specification, but it isnt something constant, because miners may decide how much a unit of gas costs. Now, it i Continue reading >>

Ethereum: Everything You Want To Know Aboutgas

Ethereum: Everything You Want To Know Aboutgas

Gas keeps Ethereum Blockchain alive, thanks to it we can transfer Ether and other Ethereum tokens such as: GameCredits (GAME), OmiseGo (OMG) or Golem (GNT), it also allows to smart contracts to do their job. In this blogpost Im going to explain: what is Gas? how is it used? and why is it so important for the future of Ethereum? Important: Dont be misled by the Token named GAS which is something completely different. Ethereum blockchain is run by nodes that keep the blockchain state but also calculate new blocks. New blocks are needed to change Blockchains state e.g. move Ethereum from one account to another. Calculation of the new block is made by miners, to cover their effort transaction sender must pay a fee. Transaction fee depends on complexity of transaction sender wants to make, if its a regular send Ether transaction or more complex one like create smart contract (smart contract a special kind of the blockchain account, that can not only keep Ether but also computer program with its state). Sending Ether from one account to the other costs 21,000 Gas. On the other hand creating smart contract which is responsible for handling OmiseGo Token costed 1,197,977 Gas. So the more complex transaction, the more Gas we need to pay for its execution on Blockchain. Main complexity factors are: operations performed by the smart contracts code e.g. arithmetical operations data that is stored on blockchain e.g. storing information in the smart contract or updating an amount of Ether on the account We know more or less what Gas is, but how much does it cost? The answer is as always it depends. Each transaction sender (e.g. person who is sending Ether) is defining price of Gas for created transaction (e.g. 1 Gas = 0.000000001 ETH). If the price is high enough, transaction will b Continue reading >>
