What Are Gas Fees in Crypto? Why Are They Important?

In the realm of digital finance, cryptocurrencies have become a cornerstone for investments, transactions, and innovations. Yet, as more people venture into this space, understanding the nuances, such as gas fees, becomes crucial. Let's dive into what these fees are and why they're essential for the crypto ecosystem.

What are Gas Fees?

Gas fees are payments made by users to compensate for the computing energy required to process and validate transactions on a blockchain network. Think of them as the transaction fees you pay when transferring money from one bank account to another but in the context of blockchain operations.

These fees aren't fixed and fluctuate based on the network's demand and supply of processing power. High demand for transactions can lead to higher gas fees, as users compete to have their transactions processed quickly.

Why are Gas Fees Necessary?

Gas fees serve two primary purposes:

1. Security: They help prevent network abuse by making it costly to spam the network with transactions.
2. Resource Allocation: They incentivize miners or validators (in proof-of-stake networks) to process transactions, ensuring the network's smooth operation.

The Current State of Gas Fees

 Here's a quick overview of the gas fees for some of the major blockchain networks:

Ethereum (ETH): Ethereum, known for its smart contracts, is the leader of the pack for having the highest gas fees. Let's take a little dive into the breakdown of these fees:

How Gas Fees are Calculated in Ethereum

Gas fees in Ethereum are determined by a combination of factors including the complexity of the transaction, network congestion, and the speed at which a user wants the transaction to be processed. Here's a step-by-step breakdown of the calculation:

1. Gas Units (Limit)
Definition: Each operation on the Ethereum network requires a certain amount of computational effort. This effort is measured in "gas," and every type of transaction requires a different amount.

Calculation: The total gas units a transaction needs are calculated based on the complexity of the transaction. For example, a simple ETH transfer requires a fixed amount of gas, while executing a smart contract function can consume much more because it involves more computational work.

2. Gas Price
Definition: Gas price is the amount of Ether (ETH) a user is willing to pay per unit of gas. It is measured in gwei, where 1 gwei equals 1 billionth of an ETH.

User's Role: Users can set the gas price higher to have their transaction processed faster, especially during times of high network congestion. Miners prioritize transactions with higher gas prices.

Network Conditions: When the network is congested, the gas price increases. Conversely, it decreases when the network is underutilized.

3. Total Transaction Fee
Formula: The total transaction fee is calculated by multiplying the total gas units by the gas price per unit.

Total Transaction Fee=GasUnits(Limit)×GasPrice

Example: If a transaction requires 21,000 gas units (a typical amount for a straightforward ETH transfer) and the gas price is set to 100 gwei, the total fee would be 0.0021 ETH. This a really simple example because as of late, we have seen gas fees go from $50 a transaction to over $100 for a single transaction. 

4. EIP-1559 Update and Base Fee
Base Fee: With the London Hard Fork incorporating EIP-1559, Ethereum introduced a base fee mechanism. The base fee is an algorithmically determined price that fluctuates based on network demand, aimed at making gas fees more predictable.

User Tips: Users can still prioritize their transactions by adding a tip (priority fee) to miners on top of the base fee.

Burning Base Fee: The base fee is burned (permanently removed from circulation), reducing the overall supply of ETH and potentially leading to deflationary pressure on Ethereum. This will help with traffic flow within the network. This will not help with the cost of transaction fees.

The introduction of Ethereum 2.0 aims to reduce these costs through a more efficient consensus mechanism.

If you want to develop a strategy to reduce gas fees on the $ETH network here are a few:

Check out websites like Milkroad. They have an $ETH gas tracker to see what days and times have the lowest gas fees so you can get it at the cheapest price.

They also have a heatmap that will break down the best times even further. So far It seems weekends and late nights/early mornings are the best to see lower fees.

Research different decentralized apps (dApps) to help reduce transaction costs. An example is Rook, where it bundles transactions together to help reduce fees. Learn more about Rook HERE. 

Consider moving a portion of your long-term holdings to other Layer-1s Alternatives that have the technology set for faster transactions and cheaper fees. Examples are Solana: between $0.003 and $0.005, Bianace Smart Chain: 0.2427, and Near Protocol: 0.5. 

Bitcoin (BTC): Bitcoin transaction fees are based on transaction size rather than complexity. Fees rise with increased network activity.

Binance Smart Chain (BSC): Known for lower transaction costs compared to Ethereum, making it a popular choice for users looking for cheaper alternatives.

Solana (SOL): Solana boasts extremely low transaction fees due to its high throughput and efficient consensus mechanism.

It's crucial to note that gas fees are subject to change based on network congestion and usage patterns. For the most current rates, users should consult their preferred blockchain's explorer or transaction fee estimator tools.
