Bought Your First Bitcoin or Ether? Brace for the Fees Dec 18, 2017 at 11:30 UTC|UpdatedDec 19, 2017 at 13:03 UTC I sent $25 of Bitcoin from one address (in Coinbase) to another (Kraken). -- Kristian Freeman (@imkmf) December 8, 2017 Ready to send your first bitcoin?That will be $26 please... Sure, that's on the high end of what you might pay to use the bitcoin blockchain today, but if you're new to the world of cryptocurrencies (and haven't invested that much), we understand seeing such a sky-high sum might be a shock. (Sorry, Kristian!) Despite what you might have heard about the "money of the future," the fact is bitcoin (and other cryptocurrencies) are both expensive - and experimental - today. But while this might not be what you're used to (or even what you signed up for when purchasing), looking at the reasons behind blockchain costs can help you understand the technology, its weaknesses and where the ecosystem needs more dedicated minds to improve. OK, so what's with fees in the first place? To start, you're probably thinking this money is all going somewhere. And it is, just not a single place. When you send a cryptocurrency transaction, you're paying for it to be included on the protocol's blockchain, which you can think of as something an official record of every token on the network ever spent (whether it's bitcoin, ether or something more exotic). Rather than holding this at a bank or a credit card firm, this ledger is distributed. This means that should any one computer (or group of computers) go down, the network still has a copy showing that you own your asset. The bad news is you have to pay all those computers to process it. Here, we'll introduce you to the first new person on our journey, the miner (or validator, depending on your network).

Green area: Total transaction fees per day, in US$; Blue line: Average transaction fee, in US$. Green area: Total transaction fees per day, in coins; Blue line: Average transaction fee, per byte of data accepted into each block, in coin's smallest denomination (except in Ethereum's case). Note that Ethereum's total network "transaction fees" are calculated by a two-step process. First, you need to understand the "gas"price. This is an extremely small figure, intended to be decoupled from ether's market price. Here we are measuring it in szabos, which amounts to 0.000001 ether per 1 szabo. Ethereum's denominations actually go much smaller than this, down to something called wei. One ether would amount to 1e18 wei; or a 1 with 18 zeros behind it. In any event, after the average gas price is understood, one would need to multiply this price by the total amount of gas units purchased in each block. Users must purchase any number of "gas" units to run different computations and contracts on Ethereum's network. The market history of both these figures is graphed below. Here, we can also see the dynamic limit that Ethereum places on gas units which can be purchased in each block. This limit is set dynamically by miners. Both are reflected in the right axis. As discussed in the network cost / block reward section, the "block reward"is essentially a revenue item for miners, and a cost item for the rest of us. Remember, it usually compromises both inflation (newly "mined" coins) and some form of transaction fees. This section isolates and graphs transaction fees only. Typically, miners choose which transactions they want to include in each block, based on how high their transaction fees are. The higher the transaction fee, the more likely your transaction is to be included and e Continue reading >>

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 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 >>

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 >>

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 >>

Crypto Glossary #3: Transaction Fee

Crypto Glossary #3: Transaction Fee

Weve reached the final part of our introduction to the crypto world. This article will provide a detailed description of what a transaction fee actually is, who collects it and how it is calculated. To do anything on the Ethereum platform, you need to pay for it, and the payment (or fee) is calculated in Ether (ETH). The fee is paid by users sending ETH over the network, and is deducted from their wallet balance. Miners, who mine blocks (confirm transactions) and secure the blockchain, receive the payment. Tx fee (transaction fee) is calculated by multiplying Gas limit and Gas price. Making sure the transactions go through without any hiccups, we charge 5 VIB for every one of them made from our platform to your preferred wallet. In other words, we add 5 VIB to the total amount of your transfer. The fee will vary depending on the price of our token. How does it work on the Ethereumnetwork? Lets suppose you have a car which consumes 1 liter of gasoline worth $10 per kilometer. If you want to drive that car for 5km, itll cost you $50. Similarly, to run a line of code on Ethereum, you burn gas limit, which has a price per unit, called gas price. Car, 10$ (gas price) per kilometer (gas limit) Ethereum, 21Gwei (gas price) per gas (gas limit) Note: Gwei is a measuring unit of gas price. It represents 1 billionth of an ETH. The default gas price and gas limit values in MyEtherWallet are: 21Gwei and 21000 gas limit. ETH price is 298$. So lets do the calculation. TX fee = Gas price (0.000006258 ETH) x Gas limit (21000) = 0.13$ Usually, when one is talking about gas in Ethereum, they are referring to gas limit. This simply means some amount of fuel is required to execute that operation or run that particular smart contract code. Gas is a unit that gets translated further into Eth Continue reading >>

Ethereum Gas And Transaction Fees Explained!

Ethereum Gas And Transaction Fees Explained!

Ethereum Gas and Transaction Fees Explained! What is mining and whats the difference between PoW and PoS mining? Basic knowledge of programming terms (variables, loops) might also come in handy. When sending a Bitcoin transaction, its fee is proportionate to its size. The more inputs and outputs , the more expensive it is. Add to that the factor of pending transactions , and transaction fees can skyrocket based on those two factors alone. With Ethereum, given that were talking about a programming language within the protocol, its possible to be very computationally demanding with very little text or code (something which would be very cheap in the BTC-verse). Lets look at this loop for example: This loop means "for as long as i is smaller than 1000, increase it by 1 and then sum up i and j and write the result into j, then do it all again." This loop will execute 1000 times if i is 0 or more if it's a negative number. To pay for this computational cost in a fair way - since it has to be executed on all miners' machines at once and they spend their resources and time on it - the concept of gas was introduced. Gas is used to pay for the execution of these so called smart contracts (Ethereum programs) inside the EVM. For example, i + j above is a summation operation which costs 3 gas every time it's executed, so 3000 gas if executed 1000 times. To explain gas properly, let's first cover the EVM. EVM stands for Ethereum Virtual Machine. But what is a virtual machine anyway? A virtual machine is software running on a specific computer which contains another operating system completely encapsulated inside the main one. A virtual machine allows you to, for example, run Windows inside of Linux, Linux inside of Windows, Windows on OS X like in the image below, or any other comb Continue reading >>
