Ethereum (ETH): The Blockchain That Turned Crypto Into an Internet Economy

I began my research on blockchain technology in 2017, and while Bitcoin seemed to make immediate sense (it’s digital currency, has a fixed supply, enables peer-to-peer transfer), I had to study Ethereum for months - learning about smart contracts, experiencing decentralized apps, and watching DeFi come into existence - before I realized that this “world computer” wasn’t competing with Amazon Web Services and Google Cloud. It was creating an entirely new type of global infrastructure: a permissionless one where code runs exactly as written with no third-party intermediary, censorship, or downtime.

Coinminutes has been documenting the development of this network since it launched in 2015 and culminated in “The Merge” in 2022. As of mid-2026, this continues to be the second-largest cryptocurrency by total market capitalization and still leads all other platforms for decentralized application deployment.

1The Basics of Ethereum

Before diving into the technical details, let's establish the fundamentals: what this blockchain actually is, where it came from, and why the terminology matters when you're getting started.

Ethereum in Simple Terms

Ethereum is a decentralized blockchain network. It allows developers to build and run applications without using the services of established server providers, organizations, and middlemen. It differs from Bitcoin as its primary function is as programmable computing infrastructure where automated execution of code occurs based on specific pre-defined rules.

Ethereum: The decentralized programmable blockchain.

This computing infrastructure can be thought of as a global computer controlled by no one. Developers can build and launch applications on top of this architecture. Each application deployed on Ethereum executes according to its code. Anyone with an internet connection can use applications built on Ethereum.

The native cryptocurrency powering this infrastructure is called Ether (ETH), used to pay for computational resources and secure the network through staking.

The Origin Story of Ethereum

In late 2013, Vitalik Buterin created a project as a 19-year-old programmer and Bitcoin Magazine writer. He wrote an original whitepaper called "A Next-Generation Smart Contract and Decentralized Application Platform". He realized that Bitcoin did not have the ability to run arbitrary apps due to its limited scripting abilities. He wanted to build a blockchain that could be used to run anything through smart contracts.

He was joined by seven other co-founders, each bringing different technical and business strengths. Gavin Wood wrote the Yellow Paper and developed Solidity, the programming language for writing smart contracts on the platform. Joseph Lubin started Consensys which made many critical pieces of infrastructure like the MetaMask wallet.

Ethereum was founded by Vitalik Buterin in 2013, with co-founders like Gavin Wood and Joseph Lubin.

According to the Ethereum Foundation, the project raised over $18 million in Bitcoin during their crowdsale in July-August of 2014. The mainnet went live on July 30th, 2015. Since then, the protocol has gone through several updates. In September 2022, Ethereum completed The Merge, its most significant upgrade to date. It moved away from energy intensive proof-of-work miners to proof-of-stake validators. The upgrade reduced Ethereum’s energy consumption by more than 99.9%, according to Crypto Carbon Ratings Institute.

Ethereum vs Ether: What Are the Differences?

The difference in terminology has caused many new users to be confused. Ethereum is the blockchain network - the base protocol and infrastructure. Ether (ETH) is the cryptocurrency that allows for transactions across the system.

When you "buy Ethereum" on an exchange, you are buying the native coin. The network itself can’t be bought or sold; it is a decentralized protocol made up of thousands of nodes worldwide.

2How Does Ethereum Work?

Understanding the technical architecture helps explain why it's different from traditional platforms and what makes it capable of supporting a global ecosystem of applications.

The Blockchain Layer

Blockchain technology is based on a distributed ledger. This is simply a ledger that stores transaction history (all of the transactions) for all parties involved in the system in chronological order. Unlike traditional databases, it is not controlled by a single organization.

Each block includes one or more transactions, a timestamp which represents when it was added to the blockchain, and a digital fingerprint of the block prior to it which is how it forms a chain (an immutable chain). As of June 2026, according to Etherscan, the average block time on the blockchain is about 12 seconds.

Ethereum is a globally distributed blockchain ledger maintained by independent nodes.

Smart Contracts: Code That Runs on the Blockchain

A smart contract is a self-executing program that runs on the blockchain. When the terms of a smart contract have been satisfied as agreed upon in advance, it will execute those agreed upon actions. An easy-to-understand example is that once you receive your ticket for a digital concert via a smart contract, it would automatically pass over ownership of the ticket from one party to another once payment has been made. This would eliminate the need for the ticketing company to act as an intermediary in this process. 

These programs allow for advanced applications such as decentralized exchanges, lending protocols, stablecoins, and governance systems. Once deployed, these applications can be used by anyone with internet access.

Nodes, Validators, and Consensus

After The Merge, Ethereum adopted proof-of-stake (PoS), under which validators stake at least 32 ETH to propose and validate blocks. As of mid-2026, roughly 36-38 million ETH are staked across about 1.06-1.10 million validators.

Validators receive rewards for proposing valid blocks and validating those blocks. However, they will lose their validator status if they go offline or experience a severe slashing penalty should they engage in fraudulent actions. Thus, the network has an economic incentive mechanism to protect it against fraud, any attack would be too costly.

After The Merge, Ethereum uses proof-of-stake.

What Are Gas Fees?

Network operations require computational resources. These are expressed in terms of "gas". A gas fee is paid by users in the form of the native currency to incentivize validators to process their transactions and execute smart contracts.

The price of gas fees changes depending on how much the community uses the network. When we were first exploring DeFi applications as a team at Coinminutes back in 2021, it was not uncommon to see simple transaction costs range anywhere from $50-$100 in gas fees due to heavy congestion. Things have certainly changed since then. According to Dune Analytics as of May 2026, gas prices for mainnet transactions under average usage levels were priced in single digit cents, thanks to a series of recent protocol upgrades.

A dual pricing system has been put into place with EIP-1559. Users pay a base fee which is permanently removed from circulation plus an optional priority fee to validators. The removal from circulation of these funds creates deflationary pressures when there is increased use of the network.

3What Is ETH Used For?

Beyond being a cryptocurrency you can trade, the native token serves multiple essential functions that power the entire ecosystem and give it fundamental utility.

Staking and Network Security

ETH holders can "stake" their holdings, which assists in maintaining the integrity of the network and provides a 2.5-3.5% annual yield, as stated by staking data aggregator StakingRewards. Users who have 32 or more units directly validate transactions, while those with less than 32 units can do so via pooled staking services.

The 2.5-3.5% annual returns that are now available for native staking create additional passive income for long-term holders, while also enhancing the overall security of the Ethereum network. The high percentage of staked participants demonstrates confidence in the proof-of-stake model that is being utilized by Ethereum.

ETH holders can earn staking rewards by helping secure Ethereum.

Collateral in DeFi

The majority of the collateral for DeFi is represented by ETH. The collateral represents users' ability to borrow stablecoins, add liquidity to DEXs, generate income through lending protocols, or take part in structured financial instruments.

As of June 2026, it is estimated that there are approximately $55-$70 billion in TVL held within DeFi (as per DeFiLlama). Therefore, given its large position as collateral in the DeFi ecosystem, ETH has created a self-perpetuating loop where increased demand due to greater use as collateral continues to increase the size and strength of the DeFi ecosystem based upon Ethereum.

Digital Asset and Store-of-Value Narrative

Following The Merge, ETH moved away from being an entirely inflationary asset, it is now a hybrid (in terms of the way the total amount of new ETH that can be created). New ETH issuance dropped approximately 88% from around 13,000 ETH daily on proof-of-work to approximately 1,700 ETH daily under proof-of-stake.

After The Merge, ETH’s issuance fell sharply.

When combined with the burn feature of EIP-1559, ETH can become net-deflationary at times of higher-than-average network use when the fees are burned greater than the number of new ETHs being issued. In this regard, many have stated that while ETH does share similarities with BTC in that both assets are seen as stores of value by investors, it also offers investors "utility" through participation within the larger Ethereum ecosystem.

ETH in Layer 2 Ecosystems

Layer 2 network ecosystems, including Arbitrum, Optimism, Base, and zkSync, use ETH as a native gas token. Each time an asset is bridged from Layer 1 to Layer 2, users will require ETH to make each transaction. This creates additional demand for ETH outside of its mainnet usage.

By the end of 2026, collectively Layer 2s are processing in excess of 50 million daily transactions, with total value locked (TVL) exceeding $34 billion, both metrics contribute to the increased utility and demand for ETH.

4Why Ethereum Matters: The Ecosystem Built on Top

Ethereum's real value isn't just the technology itself - it's the massive ecosystem of applications, financial protocols, and digital assets that have been built on top of it over the past decade.

Decentralized Applications

Thousands of decentralized apps (dApps) are currently running on Ethereum. Many types of dApps exist such as finance, gaming, social media, identity, governance, etc... These dApps have one thing in common: they run off a blockchain instead of a server controlled by a corporation. Users can control their own data and assets. The users' rights to use these apps cannot be revoked or arbitrarily removed.

Popular dApps include Uniswap (decentralized exchange processing billions in daily volume), Aave (lending protocol), MakerDAO (stablecoin issuance), and countless others serving millions of users worldwide.

Ethereum supports thousands of dApps across DeFi, gaming, identity, governance, and more.

DeFi: Financial Apps Without Traditional Banks

DeFi is the most advanced application of Ethereum. It is an ecosystem that provides financial instruments such as loans, lending, trading, generating income through "yield", and access to financial tools outside the realm of traditional banking systems, brokerage firms, etc.

When I borrowed stablecoins using Aave against my ETH for the first time, it was quite impressive. There were no credit checks, no approval processes needed to open an account, and no set business hours. The only thing that happened after I provided collateral for the loan was that the protocol automatically ran the predetermined code regarding the collateral-to-loan ratio. I received the funds immediately upon executing the transaction via my wallet.

As per DeFiLlama's multi-blockchain analytical data, at present, approximately 63%-68% of the total value of money being held by all decentralized finance platforms, resides on the Ethereum blockchain. As a result of these network effects, development occurs in places where liquidity exists. Liquidity tends to aggregate in areas where mature protocols are operating.

NFTs and Digital Ownership

Beginning with Ethereum's introduction of a set of open standards for use in non-fungible tokens (NFTs) such as ERC-721 for non-fungible digital items and ERC-1155 for both fungible and non-fungible digital items, we are seeing an increase in proven digital ownership and cross-wallet marketplace and application compatibility.

Beyond digital art and collectibles, NFTs now also include game items, membership tokens, concert tickets, intellectual property rights, and in some cases, even represent physical assets that have been brought onto the blockchain through the use of tokenization. In terms of the value of these types of transactions being processed by the Ethereum network, data from CryptoSlam indicates the majority of high-value NFT transactions occur on this network.

Ethereum’s NFT standards enable interoperable digital ownership beyond digital art and collectibles.

Stablecoins and Tokenized Assets

There is more than $265 billion of stablecoins held by Ethereum. Most stablecoins including USDT (Tether), USDC (Circle), and DAI (MakerDAO) are built on top of the Ethereum blockchain which makes it the most popular Layer 1 for crypto-native financial transactions.

Traditional financial instruments such as government bonds, money market funds, and tokenized securities represent the next generation of real-world assets that will be on-chain. The current estimate of non-stablecoin RWAs on the Ethereum blockchain, according to Coinminutes’ research, is approximately $23 billion. Institutions are using the Ethereum network as their preferred Layer 1 for settlement of tokenized financial products.

5Ethereum vs Bitcoin: What Makes Ethereum Different?

Both Bitcoin and Ethereum are leading digital currencies but were developed with two very different goals in mind. Understanding what those goals are will be key to developing a well-rounded cryptocurrency investment portfolio. 

Bitcoin was created primarily to function as peer-to-peer electronic cash (an exchange mechanism) and as a store of value and payment method. Ethereum was developed as an open-source platform to enable application development on top of decentralized infrastructure.

Main differences between Ethereum and Bitcoin.

While Bitcoin enables the transfer of value similar to Ethereum, its main contribution has been providing a simple, secure monetary asset. Ethereum provides “digital oil” - an open-source platform upon which new applications and forms of economic activity are being developed. Most diversified cryptocurrency portfolios contain both assets because of their complementary uses instead of competitive uses.

6Benefits, Limitations, and Risks of Ethereum

Like any technology or investment, Ethereum comes with significant advantages but also real limitations and risks that anyone using or investing in ETH should understand clearly.

Key Benefits

Network Effects: Ethereum has the biggest smart contract development community, greatest DeFi liquidity, and a lot of experience with the tooling to build and use apps on it.

Reputation from Institutional Players: Financial players are using Ethereum as an asset to tokenize their assets and settle stablecoins. ETH Spot ETFs were launched in 2024.

Operational Reliability: There have been no significant attacks on the Ethereum network since its inception in 2015. Through many updates, the network has shown that it is reliable operationally.

Annual Staking Rewards (Yield): Unlike Bitcoin, annual staking rewards on ETH can be up to 3.5%.

Potential Deflation: With reduced ETH creation and fees burned at the same time, there will be times when ETH supply reduces.

Common Limitations

Throughput Issues: The Ethereum main network can process about 23 blocks, or 23 new transactions in one second which is far below what other newer blockchain systems such as Solana have achieved. 

Complexity: To use Ethereum successfully, you need to be familiar with wallets, transaction signing (and validation), how to pay gas for each transaction, and what are the most secure ways to transact on this platform. 

Fragmented User Experience: Although Layer 2 solutions help to alleviate some scalability problems that exist with the Ethereum main network, they also lead to a fractured experience for users. 

Price Volatility: ETH's price volatility has been much greater than most established asset classes.

Main Risks

Smart Contract Risk: Smart contracts are prone to bugs or vulnerabilities that may result in loss of money when utilizing DeFi protocols. 

Regulatory Uncertainty: In addition to an uncertain environment, regulations continue to evolve. This uncertainty may cause restrictions on how ETH may be utilized, as well as its access. 

Competition: Other newer blockchain systems provide faster transactions at a lower cost. As Coinminutes reported, during 2025-2026, Solana has been able to capture a large share of the existing ETH user base. 

Market Risk: The value of ETH is determined based upon the sentiment of the overall cryptocurrency marketplace, macroeconomic factors, and development related to regulation.

Using Ethereum More Safely

Begin with small amounts as you learn. Most people use either a wallet such as MetaMask or a hardware wallet like Ledger or Trezor. Always double-check that the address is correct. Once an Ethereum transaction has been sent, it cannot be reversed. Only use well-established DeFi platforms which have had many years of successful operation and also have gone through at least several security audits by companies like Trail of Bits or OpenZeppelin. Never give your private keys to anybody.

7The Future of Ethereum: Scaling and Layer 2

Ethereum's roadmap focuses heavily on scaling—increasing transaction capacity while maintaining decentralization and security—with Layer 2 networks playing the central role in this strategy.

Layer 2 Networks Explained

The Layer 2 network is a separate blockchain from the mainnet. It processes the transactions in batches then posts the batched information back onto the mainnet (base layer) at intervals. The result of this process provides for much higher levels of throughput on the base layer, and therefore significantly lower transaction costs. Layer 2 transaction costs fall into the "fraction of a cent" range per transaction, as illustrated by the technology documentation provided by both Optimism and Arbitrum.

Some major Layer 2 solutions include Arbitrum, Optimism, Base, zkSync and Starknet. According to L2Beat, these Layer 2 solutions have processed more total daily transactions than the mainnet has since their introduction.

Ethereum's Roadmap

Ethereum follows a roadmap shaped by Vitalik Buterin and other core contributors. Recent upgrades like Dencun (March 2024), and Pectra (May 2025) have increased the total capacity of the blockchain while also reducing the cost of processing transactions on Layer 2, as mentioned in the Ethereum Foundation's upgrade announcements.

Glamsterdam is planned to be released later in 2026. It is expected to include improvements that will allow Ethereum to increase its block gas limit towards 200 million. This should provide an even greater amount of base-layer space for users.

Ethereum development follows a structured upgrade roadmap, with the upcoming Glamsterdam upgrade in H2/2026.

What Ethereum Could Become

Ethereum is increasingly being positioned as settlement infrastructure for tokenized finance could potentially evolve into an environment where most of today's traditional assets and financial instruments will exist on some sort of blockchain. Theoretically, if Ethereum's vision becomes a reality it may be considered the foundational layer for tokenized finance much like TCP/IP has been to the Internet. As reported by BlackRock and Franklin Templeton, some institutions view Ethereum as a strong candidate for on-chain financial settlement, though that outcome is far from guaranteed.

We see this vision being supported by growing institutional adoption. However, this is not a guarantee, as competitors continue to innovate and there are many challenges facing Ethereum's roadmap that need to be executed.

8A Final Word on Ethereum

Ethereum represents blockchain's most ambitious experiment: building programmable infrastructure that operates without central control while supporting financial applications and decentralized coordination. Since its 2015 launch, it has evolved into the dominant platform for DeFi, NFTs, and tokenization, processing billions in daily transaction volume.

The successful proof-of-stake transition and recent scaling improvements demonstrate genuine technical progress. As of 2026, Ethereum offers economically viable infrastructure with dramatically lower fees than just two years ago, institutional credibility through regulated investment products, and network effects that competitors struggle to overcome. Whether it emerges as foundational internet infrastructure or remains a specialized platform depends on continued innovation, competition, and real-world adoption. However, it undeniably represents essential knowledge for anyone seriously exploring crypto.
