What Is Ethereum And How Does It Work?
The Ethereum network can also be used to store data and run decentralized applications. Rather than hosting software on a server owned and operated by Google or Amazon, where the one company controls the data, people can host applications on the Ethereum blockchain. This gives users control over their data and they have open use of the app as there’s no central authority managing everything.
Perhaps one of the most intriguing use cases involving Ether and Ethereum are self-executing contracts, or so-called smart contracts. Like any other contract, two parties make an agreement about the delivery of goods or services in the future. Unlike conventional contracts, lawyers aren’t necessary: The parties code the contract on the Ethereum blockchain, and once the conditions of the contract are met, it self-executes and delivers Ether to the appropriate party.
Ethereum vs Bitcoin
Bitcoin’s primary use is as a virtual currency and store of value. Ether also works as a virtual currency and store of value, but the decentralized Ethereum network makes it possible to create and run applications, smart contracts and other transactions on the network. Bitcoin doesn’t offer these functions. It’s only used as a currency and store of value.

Blockchain affords immense benefits to many use cases in the financial industry and others. But use of a powerful decentralized computing network like Ethereum comes at a cost.
The Ethereum blockchain is secured by a decentralized group of miners, who are paid for their work. This payment ensures that the miners behave properly and prevents spammers from clogging the network.
But what happens when the demand for computing power on the blockchain outpaces the limits of the network? Fees skyrocket and small transactions become entirely uneconomical.
This is happening right now, and Ethereum is under intense pressure to expand their network capabilities. Currently, Ethereum can handle around 15 transactions per second. For reference, Bitcoin can handle around 5 and major credit cards can handle around 3,000.

What Determines Ethereum Gas Prices
The cost for power, or space on the Ethereum blockchain, is set by the market. Gas fees fluctuate constantly depending on the number of miners working, and the number of decentralized applications (DApps) being used at any given time.
Different types of blockchain interactions require different amounts of computational power, called gas. Each unit of gas has a price, and the gas price is known as GWEI.
When interacting with the blockchain, the amount of gas is based on the action, but you decide your gas price. By selecting a GWEI over the market price, you can be sure that your transaction will get processed quickly. If you can wait, you can set a lower GWEI and hope it gets filled when the market is quiet.
Wallets such as MetaMask simplify this process for users, allowing them to choose slow, medium or fast.
Why are Ethereum Gas Fees So High?
DApps powered by Ethereum can do anything from mint NFTs to provide automated liquidity pools. Because Ethereum has the largest decentralized network capable of handling smart contracts, it’s theoretically the most secure option for DApps to run on.
This demand for Ethereum is clearly shown by the sky-high gas fees. Minting an NFT can cost upwards of $100, making them inaccessible for a lot of low-budget artists right now.
The same goes for gaming and other low-volume financial applications that could see huge benefits from the blockchain as soon as it becomes more affordable.
Ethereum gas prices might drop much sooner than you think.
How Ethereum 2.0 Will Drastically Lower Gas Prices
Ethereum has ambitious plans to scale the network to handle 150,000 transactions per seconds by the end of 2021. A major network overhaul, dubbed Ethereum 2.0, promises to deliver on this scale at the same time as making the network more secure and eco-friendly.
Ethereum 2.0 will upgrade the network from Proof of Work (PoW) to Proof of Stake (PoS). Proof of Stake networks are maintained by validators, who stake currency in exchange for the right to verify transactions. They earn the reward associated with each transaction they verify, which is estimated to payout around 7.5% of your staked tokens yearly.
Proof of Stake eliminates the energy-intensive problem solving from the PoW model, but the bump in transaction volume comes from sharding.
Sharding splits up each block of transactions into smaller chunks called shards. These shards are distributed randomly and secretly to validators. Before sharding, each miner was responsible for authenticating every transaction in the block. This much duplicate work made the system secure, but the randomization aspect of sharding actually makes it more secure than the previous system.
When Ethereum 2.0 is complete, the network should be able to handle between 100,000-150,000 transactions per second, but the upgrade has been on the way for years with multiple delays already.
With so much demand for Ethereum, there needs to be a quicker solution: Enter Layer 2.
Ethereum Layer 2
Large amounts of transactions can be offloaded to layer 2 applications via Ethereum smart contracts. These smart contracts anchor layer 2 solutions in the security of the base level blockchain without clogging the network.
An a16z-backed startup called Optimism promises to allow Ethereum to process 2,000 to 3,000 transactions per second by May 2021, drastically reducing fees.

Pros and Cons of the Ethereum Network
Ethereum is a platform for building decentralized applications. Developers choose to build on Ethereum because of it’s turing-complete programming language, Solidity, which makes developing smart contracts really easy.
They also choose Ethereum because of its large decentralized network of miners. Remember more decentralized is directly correlated to more security.
The downside to Ethereum is it’s outdated proof of work consensus model and low transaction volume. This is the biggest hindrance to the project currently, and the reason Bitcoin has been outpacing it so much in 2021.
Layer 2 solutions like Optimism promise to bring scale soon enough to buy Vitalik Buterin and his team more time to finish up the Ethereum 2.0 overhaul.
ETH in Your Tank
Ethereum is the biggest and most decentralized smart contract platform in the blockchain space today. Despite it’s outdated transaction volume, promised upgrades have kept users and developers interested in the platform.
Currently, Ethereum can only process around 15 transactions per second, so those willing to pay the most are the ones that get through. To find out when the best time is to make a transaction use a network monitoring tool such as gasnow.org.
Frequently Asked Questions
Neo launches N3 amid high Ethereum gas fees · TechNode
Neo, an Ethereum alternative and one of China’s oldest blockchain protocols, is starting to roll out a third version of its public blockchain infrastructure, dubbed N3.
Why it matters: N3 is a make-it-or-break-it moment for one of China’s most promising and globally recognized blockchain projects. The team has been working on the update for years. On paper, N3 hits all the right notes for becoming a widely used blockchain protocol. But it will need to stand out from an increasingly competitive crowd.
The upgrade comes at an opportune time: The Ethereum network is facing critical capacity challenges, meanwhile the Chinese government highlighted blockchain as a strategically important technology in the latest Five-Year Plan.
Founded in 2013, Neo is one of many Ethereum alternatives looking to attract developers to build decentralized applications on its blockchain.
Details: The original planned launch date for Neo’s third iteration was in 2020, but it was pushed back to Q1 2021 because the system wasn’t ready, Da Hongfei, co-founder of Neo, told TechNode. It is difficult to predict a specific time for a community-driven project, Da said. Like most public blockchains, the code was developed by a small team of core developers and a wider global developer community.
N3 will increase transaction speed on the network from 1,000 per second to 5,000 and reduce transaction charges, known as “gas fees,” by 100 times, according to a Neo press release emailed to TechNode.
Cheap gas is strategically important to compete with the Ethereum network, whose rocketing transaction fees have sent developers looking for greener pastures.
The new version of the chain will also include oracle integration, a decentralized file storage solution similar to Filecoin’s IPFS, and a new governance mechanism.
Oracles like Chainlink and decentralized storage like Filecoin are relatively new, viable blockchain features. When Chainlink and Filecoin broke out with their solutions in 2020, their coin prices soared. Just like a car needs gasoline to run, the Ethereum virtual machine needs gas. Gas fees are essentially transaction fees that users pay to miners to include their transactions in blocks, which make up the ever-growing blockchain ledger. Ethereum miners can pick which transactions to execute, so the higher the demand for execution—reflecting an increase in the number of people wanting to use the network—the higher the gas fees.
Neo’s focus is digital assets, so the co-founder said the community is “encouraged” to build fundamental infrastructure for decentralized finance, such as landing and swap protocols.
Oracles are key to DeFi because they connect the real world to blockchains. Da also sees N3 as a good place to build non-fungible tokens (NFTs), due to the decentralized file storage feature.
Da said that because developers were waiting for the network upgrade, they hadn’t been building many dapps on Neo.
Migration: The migration of Neo tokens to the new network will take place using a consortium interoperability protocol Poly Network developed by the team behind Neo.
Exchanges and wallets take care of token migration, the process by which old tokens are converted into new tokens on the new chain, using smart contracts.
Radical changes to the blockchain protocol such as the ones N3 will implement usually take place through a so-called hardfork: The chain splits in two parts, and the change is implemented in one.
Instead of a hardfork, Neo will use an interoperability protocol, a type of chain that enables the transfer of information from one blockchain to another, to create a completely new chain.
“We will be the first blockchain in the world to do a completely new chain through an interoperability protocol,” Da said.
These protocols are at the frontier of blockchain development and crucial for mass adoption: They promise to connect chains that currently exist as islands to create an internet of blockchains.
The N3 migration will test whether Poly Network can be used to create a blockchain from scratch and correctly transfer all the data from the existing chain.
The Ethereum challenges: The Ethereum network has been facing significant challenges in the last few months, and developers are scrambling to find alternatives for their dapps. Gas fees have been hitting record highs as the network becomes congested.
Da Hongfei, Neo’s co-founder (Image credit: Neo) Ethereum “has reached its maximum capacity,” Da said. Transactions per day have plateaued at around 1.2 million to 1.3 million since August, while alternatives like Binance Smart Chain are reaching record-high transaction volumes.
The update to Ethereum 2.0 would likely solve some of these problems, but has been continuously put off. Da thinks we won’t be seeing it for a few years: “It’s difficult to deal with different interest groups,” particularly miners, he said. The upgrade will hurt their bottom line by drastically changing how they are rewarded.
“At the end of the day, Ethereum is one blockhain but everyone needs to maintain a ledger. The capacity growth of the Ethereum ledger will not outpace the growth of demand,” so there is room for many different protocols to grow, Da said.
Government tailwinds: Blockchain’s inclusion in the 2021-2025 Five-Year Plan will “definitely” bring more investment to the technology, Da said.
