Lucky for you, MetaMask calculates the approximate gas fee you should set for you based on how fast you want your transaction to be confirmed. When you submit a transaction on Ethereum, you are competing with others who also want to submit a transaction. While you might be sending your mom some Ether, someone in India might be trading on Uniswap. Each person is trying to have their transaction executed at the same time. But, only so many transactions can be included in an Ethereum block, and there are only new blocks every roughly 13 seconds.

In fact, each block contains only This means everyone is competing against one another to have their transaction included in the next block. When demand is high, and supply is constrained since only so many transactions can be included in a block, price must increase.

But when you submit transactions, where do they before miners approve them? In short, the mempool is the waiting queue for validation. Miners select what transactions should be included in the next block based on how high the gas fee users set prior to submitting the transaction. The higher the gas fee, the higher chance a miner will be willing to include your transaction in the next block.

This situation is where the competition comes in, since you compete with everyone else setting gas fees during that time frame for block space. Since all users compete against one another for block space, when you set your gas fee too low, miners will opt not to include your transaction in a block in the near future. Thus, your transaction takes so long because you did not set the gas fee high enough for your transaction to be included in a near future block.

You will have to wait for the gas fees that other users are willing to pay to go down for your gas fee to be attractive to miners.

The demand for scalability is becoming increasingly urgent. The Cryptokitties incident demonstrated how quickly the Ethereum network can clog-up. Here's a simplified guide to Ethereum for those who want a refresher. One of the major problems of a blockchain is that an increase in the number of nodes reduces its scalability.

This may seem counterintuitive to some people. One of the reasons a blockchain has its level of security is because every single node must process every single transaction. This is like having your homework assignment checked by every single professor in the university. While this may ensure that your assignment is marked correctly, it will also take a really long time before you get your assignment back. Ethereum faces a similar problem. The nodes are your professors. Each transaction is your assignment.

Sure, we can reduce the number of professors nodes until we are satisfied with the speed. But as the assignment transaction backlog increases, we will need to further decrease the number of professors. A centralized group. This defeats the ideology of blockchain decentralization.

As a result, we sacrifice security in an effort to scale. So in our professor analogy, a shard would consist of a group of professors and assignments. Now, instead of a professor having to correct the assignments across the entire network, he would be only responsible for the assignments within his shard group. This greatly reduces the number of transactions assignments each node professor has to validate. Okay, so I may have oversimplified a tiny bit.

Finally, we have super-nodes. Each super-node receives the collations created by the collators of each shard. They then process the transactions within those collations. You can probably see the benefits of this structure. The number of nodes that process every single transaction would be greatly reduced, and thus increase overall throughput. Sharding is a smart approach to tackling the blockchain scalability problem.

Proof Of Stake helps mitigate this security vulnerability that comes with Sharding. But for the sake of brevity, we will discuss that in a future post.

Gas prices are generally lower due to the reduced volume of traffic in those blockchains, and a significantly smaller number of DApps operating on them, at least when compared with Ethereum. Many different technical approaches are being developed in parallel in order to scale the capacity of Ethereum, increase throughput and lower Ethereum gas fees. Out of these, rollups are beginning to show themselves as a promising solution.

By using Ethereum as the base layer and inheriting its security and decentralization, rollups allow users to make transactions without congesting the Ethereum network. The development and integration of different rollup solutions could foster a climate of commonwealth, rather than predatory competition.

In any case, the whole Ethereum ecosystem will benefit from these technological innovations. The roadmap towards Ethereum 2. Ethereum founder Vitalik Buterin recently published his views on the power of ZK rollups on the scalability issue facing Ethereum:. In the same way that rollups can scale Ethereum 1. At the time of writing, it is hardly feasible to trade or transfer tokens on UniSwap due to gas prices.

Expensive network fees and low volume of processing transactions are blocking the way to mainstream adoption of digital currency. In the coming years, this will change completely, and soon we will be able to cheaply and efficiently transfer value between us all. CoinMarketCap News. What Are Gas Fees? Table of Contents. What Are Gas Fees in Ethereum?

By David Schwartz. The system works on a standard supply and demand mechanism. If there is more demand for transactions, miners can choose to include the transactions that pay more, compelling users to pay more to have their transactions processed quickly and efficiently. Users of Ethereum can also choose to pay more for faster transactions, as seen in the diagram below. Wallets like MetaMask enable users to interact directly with the Ethereum network, choosing which amount of gas they wish to pay.

There are several websites where you can track gas prices, like ethgastation. This requires significant computing power to compete and resources to maintain. Users of the Bitcoin network pay transaction fees to miners, incentivizing them to continue validating the network. However, this becomes a problem when there are a shortage of miners and high demand for block space. This happened in April , when miners in China suffered an outage due to coal mines accidents, resulting in a drop in hashrate, slower block times, backlog of transactions and extra fees per block.

Ethereum gas fees are not always astronomical, but they have spiked to incredibly high levels during peak periods in the past such as the ICO boom and the DeFi summer of , both times where the value of Ethereum and the number of projects in the space skyrocketed, bringing congestion to the Ethereum network.

In many instances, Ethereum gas fees can be outrageous for most use cases. However, rising gas fees does demonstrate that there are real use cases for Ethereum and the decentralized applications DApps are built on top of it. Lending , borrowing, flash loans , derivatives , yield farming and decentralized insurance were all popularized very quickly. DeFi was a booming ecosystem, and it also had its share of several hacks, rug pulls and other dramas.

On this chart from Gitcoin , you can see the evolution of gas prices over the last 14 weeks from May to August An increase in usage — which tends to come with the appreciation of ETH — means an increase in Ethereum gas fees for the whole network. Ethereum's dominance as a base layer Layer 1 for Web 3. The main feature of many of these projects is to offer lower gas fees and in some cases, a higher throughput , or volume of transactions per second TPS.

It is inevitable that some DApps are being priced out of the main Ethereum chain. These DApps often do not need composability with other Ethereum DApps and will move to side-chains, alternative chains or Layer 2 solutions. A user constructs and signs a transaction, and each user may specify whatever gasPrice they desire, this includes zero. However, the Ethereum clients launched at Frontier had a default gasPrice of 0. As miners optimize for their revenue, if most transactions are being submitted with a gasPrice of 0.

How the default was chosen is asked in this question. Let's take a contract that just adds 2 numbers. From the spreadsheet above ADD consumes 3 gas. This is a simplification since it ignores some costs, such as the cost of passing the 2 numbers to contract, before they can even be added. Each instruction in Ethereum Virtual Machine has a cost, measured in units of gas. The table of such costs for each instruction is called "Fee schedule" and is an appendix in the Ethereum Yellow paper it might change in the future though.

The only way to determine in general how much gas a certain call to a contract would cost is to run it not necessarily on the blockchain, but in a 'local simulator'. However, if the contract code interacts with the state of the blockchain e. Therefore, in some cases, the real cost of execution will only be known when the transaction is included in the block. That is why you can try to estimate the upper bound of how much gas will be required and send enough ether with the transaction.

Because if it is not enough, transaction fails with "Out of Gas" exception, and the ether is not refunded. Sign up to join this community. The best answers are voted up and rise to the top.
