In the first few years after its creation, Bitcoin reigned unchallenged as the leader of the blockchain world. Early cryptocurrencies like Litecoin were simply its forks – projects built upon Bitcoin’s code with minor modifications and new features. Yet, this approach eventually frustrated many developers in the crypto community.

Bitcoin’s original architecture limited how digital assets could be integrated into broader financial systems, preventing full use of the technology’s potential. Out of this desire for innovation, Ethereum was born – a cryptocurrency that quickly became the main rival to Bitcoin, often called “digital gold.”

What Is Ethereum

Ethereum Platform for Decentralized Applications (DApps) and Smart Contracts
Ethereum

Ethereum serves as a flexible platform for building decentralized applications powered by smart contracts. Ether (ETH) acts as the ecosystem’s internal currency, facilitating transactions and network operations. Although sometimes referred to as “Bitcoin 2.0,” Ethereum has a completely different purpose and philosophy.

The main value of the Ethereum network lies not in the coins but in the capabilities of the virtual platform. A wide variety of blockchain projects – ranging from sports betting and online casinos to charitable foundations and NFTs – run on Ethereum. Getting access to the system is very simple: you just need to enable the MetaMask browser extension.

Who Created Ethereum

Vitalik Buterin, Main Founder and Creator of the Ethereum Project
The origins of the Ethereum project trace back to Russian-Canadian programmer Vitalik Buterin.

The project’s origins trace back to 2013, when a young Canadian programmer, Vitalik Buterin – also the founder of Bitcoin Magazine – and his colleague Gavin Wood introduced the concept of the Ethereum blockchain. Unlike Bitcoin, Ethereum was designed not only as a currency but also as an infrastructure for decentralized web services to exchange resources on a peer-to-peer basis.

A year later, during the ICO campaign, the team raised 31,000 BTC (around $18 million). This success drew attention from major financial institutions. Ethereum’s test network went live in the summer of 2015, and full functionality was released nine months later with the rollout of the Homestead protocol.

In June of that same year, a vulnerability was found in the code of The DAO – a system that autonomously managed investment capital. Due to a bug, hackers stole roughly one third of all the coins, moving them into a side branch called ChildDAO, which was fully under their control. Nonetheless, thanks to the specifics of The DAO, those funds were frozen for a month.

Vitalik Buterin, together with part of the Ethereum community, decided to return the money to investors. As a result, on 2016-06-20 a hard fork (a split of the blockchain) took place, reversing the changes made by the hackers. Another part of the community chose to remain with The DAO, giving rise to the Ethereum Classic network.

Why Ethereum Is Needed

The Merge marked Ethereum’s transition from Proof-of-Work (PoW) to Proof-of-Stake (PoS).

Ethereum made blockchain technology accessible to anyone. Instead of building a new blockchain from scratch, developers could now launch their own projects using Ethereum for a relatively small fee. This made it possible for countless applications – written in different programming languages – to interact within one network, vastly expanding blockchain’s use cases.

As Vitalik Buterin put it, Ethereum represents a new kind of internet, rich with possibilities. The foundation of this innovation lies in smart contracts – programs that automatically execute agreements when predefined conditions are met. For example, “If a person pays $2, the vending machine dispenses a coffee.” These self-executing contracts ensure transparency and trust without intermediaries.

Thus, any qualified programmer can build their own application on Ethereum’s ecosystem that operates according to a strictly defined algorithm. The system guarantees protection against failures and malicious actors, freedom from censorship, and non-interference by external regulators. If one of the nodes servicing a smart contract fails, the application will switch to another node and continue to operate stably. Information generated during execution remains immutable thanks to distributed storage across thousands of nodes.

The Ethereum network makes it possible to:

  • Launch complex smart contracts to manage logistics chains.
  • Create applications of any type (NFT games, utilities, etc.).
  • Tokenize physical assets (oil, gold, gemstones, industrial goods).
  • Manage customer identification and document authenticity services.
  • Organize decentralized trading platforms.

In theory, you could even run electronic voting for elections on the Ethereum blockchain.

In addition, many ICOs are conducted on the Ethereum platform, for which a single token standard called ERC-20 was developed (“Ethereum Request for Comments”). The ERC-20 standard ensures that all projects meet fixed security standards and remain interoperable within the network.

It was the launch of the ETH ecosystem that triggered a true boom in the ICO market. A newcomer learning the basics of the crypto industry will be surprised to discover that, besides ETH, a large number of other cryptocurrencies run on Ethereum’s blockchain. And any user can issue their own tokens – albeit strictly according to predefined parameters. Adhering to the ERC-20 standard is necessary to ensure that one’s own virtual assets interact normally with the rest of the system.

Creating a project on Ethereum is both affordable and straightforward, which is why the ecosystem rapidly filled with decentralized applications and startup tokens. Fundraising through token sales became a norm, mirroring stock offerings but using crypto instead of fiat money.

Ether (ETH), the network’s native currency, powers all these activities – it’s essentially “fuel” for executing smart contracts. The Ethereum Virtual Machine (EVM) manages these operations while protecting the network from denial-of-service attacks and unauthorized access.

When a new program is activated or a transaction is executed, the network processes data compiled into bytecode, which the virtual machine decodes and executes. Thanks to the EVM, applications written in different programming languages can interact effectively.

Where the Coins Come From

Every transaction in Ethereum is permanently recorded on its blockchain – a continuous chain of encrypted data blocks. Validators play a key role in this process: they confirm transactions, form new blocks, and compute cryptographic hashes that secure the network.

Generation takes roughly 15 seconds; after that the block is verified and written to the blockchain. For each added block, the validator receives a reward of 2 ETH; part of the reward is paid out to stakers who have delegated funds to that validator’s node. The next block is assigned to another validator. They thus take turns participating in servicing the network.

Block Explorer

Each blockchain project typically includes a block explorer, a tool that allows users to track transactions and monitor activity. However, with thousands of active networks today, a universal search engine for all blockchains still doesn’t exist, making seamless cross-network tracking a challenge.

The official website of this search and analytics service for Ethereum is https://blockchair.com/ethereum.

The interface is available in seven European languages. Developers are given access to an API with support for filtering, sorting, and aggregating information. The Blockchair Feed option allows you to read texts placed on the Bitcoin, Bitcoin Cash, and Ethereum blockchains on the fly. It also displays messages from the decentralized social networks Blockpress.com and Memo.cash. You may not have known this, but blockchain ecosystems are not just dull ledgers that store only records of financial transactions between network users. There is other, more interesting information there too – including “The Hacker Manifesto” by Lloyd Blankenship, political and economic news, and even declarations of love! In Ethereum’s distributed ledger, such data are stored in the “input” and “extraData” fields, while in Bitcoin and Bitcoin Cash they are found in transaction scripts; the best-known, OP_RETURN, is often used by visitors to “decentralized Twitters.” As is well known, immutability is a key property of blockchains, which means no information can be erased or edited.

What Backs Ethereum

The question of what backs Ethereum – just like what backs Bitcoin or other coins of decentralized networks – has been asked by cryptocurrency skeptics for many years.

They should be asked a counter-question: “What backs the U.S. dollar, the only monetary unit in the global financial system?”

Fiat money no longer has tangible backing such as gold; its value rests solely on collective trust and geopolitical dominance. In that sense, the dollar is “backed” not by assets, but by military and economic power.

The Ethereum platform makes it possible to do without intermediaries when concluding deals, protects against external interference and censorship, and ensures immutability and security. New ether coins are created according to a strictly defined algorithm embedded in the system’s code; all transactions are protected by cryptographic signatures. In essence, Ethereum is “backed” by all the advantages of blockchain technology and by code features that allow the platform to be used for executing smart contracts.

The system automatically evaluates the terms and circumstances of a deal and analyzes its safety. Transactions are also carried out without human participation; on Ethereum, smart contracts are considered executed after confirmation by the counterparty and are not reversible. The results are recorded in a public ledger.

The capabilities of the Ethereum network are of interest to big business, and a global community – the Enterprise Ethereum Alliance (EEA) – has been created. Within it operate 19 technical, industrial, and legal advisory groups. The EEA has 250 member companies from 45 countries, among them:

  • Microsoft;
  • JP Morgan;
  • Intel;
  • Sberbank.

All members are actively exploring how to build a global blockchain economy.

Skeptics once called Bitcoin a speculative bubble, arguing it had no intrinsic value. Interestingly, the same critique rarely appears in discussions about Ethereum – a sign of how differently the crypto world views these two blockchains.

Why is that? Perhaps because of the project’s support base. Not only ordinary network users but also business giants are interested in the development of the Ethereum platform. Heightened attention from big capital and the widespread expansion of practical use cases make this digital asset popular and valuable.

The Difference Between Bitcoin and Ethereum

Now, let’s take a closer look at what truly sets Ethereum apart from Bitcoin. We briefly mentioned them at the beginning of the article, but let’s analyze them in more detail, systematize them, and put them into a table.

By and large, Bitcoin and Ethereum are not direct competitors. Ethereum is an internal payment instrument for clients of a decentralized system, while Bitcoin is an international financial tool that allows for anonymous payments with minimal fees.

In the Bitcoin network, the cryptocurrency is the end product—the entire meaning of its blockchain’s existence. Bitcoin is the digital analog of dollars, rubles, and other national currencies. ETH coins are more akin to digital shares of a company providing services to clients within a peer-to-peer network.

Transition to PoS “Mining”

Since Ethereum’s transition to the Proof-of-Stake (PoS) mechanism, mining has officially ended. Following the merge of the ETH 1.0 and ETH 2.0 networks, a fork known as ETHW was created, rewarding all ETH holders with equivalent tokens. ETHW runs on Proof-of-Work, so it remains mineable but has a distinct value and market position.

If you have accumulated 32 ETH, you can become a validator and continue earning by helping to service the second-most-powerful ecosystem after Bitcoin. If you don’t have that amount, no problem – you can join one of the ETH staking pools. Here’s how.

ETH Staking

Lock ETH to stake on Ethereum

To participate in Ethereum 2.0 staking, you must lock 32 ETH in a special smart contract – something you can easily do via services like MyEtherWallet (MEW). When making a deposit, a mnemonic phrase is generated; it must be stored securely and never shared. The staked funds remain locked until the next network update, after which withdrawals will be enabled.

Validators in PoS networks perform the same functions as miners in PoW (proof-of-work) networks: they verify transactions and sign blocks. In the updated Ethereum network, validators are penalized for attempts to harm the blockchain. They are not only deprived of the right to participate in consensus but also lose all funds at that address (“slashing”). Inactivity entails fines. If such measures were applied to our members of parliament, they would probably work much more effectively. Therefore, if you want to become an Ethereum 2.0 validator, make sure your node runs continuously—otherwise you will be left without rewards. Recommended system requirements:

  • Operating system: 64-bit Linux, macOS, Windows
  • CPU: Intel Core i7-4770 or AMD FX-8310 (or better)
  • RAM: 8 GB
  • Minimum free SSD space: 100 GB
  • Minimum internet bandwidth: 10 Mbps

Client software options include:

  • Prysm — the most popular and reliable Ethereum 2.0 client. Written in Go, GPL-3.0 license. Docs: https://docs.prylabs.network/docs/getting-started.
  • Lighthouse — written in Rust with an emphasis on security and high speed. Apache 2.0 license. Docs: https://lighthouse-book.sigmaprime.io.
  • PegaSys Teku — a Java client for institutional needs. Apache 2.0 license. Docs: https://docs.teku.pegasys.tech/en/latest/HowTo/Get-Started/Build-From-Source.
  • Nimbus — an experimental Ethereum 2.0 client in the Nim language. Nim resembles Python syntactically and compiles to C. Oriented toward future mobile use. Docs: https://nimbus.team/docs.

You can buy a “plug and play” setup at https://www.dappnode.io or https://ava.do. A detailed guide to setting up a validator node is available at https://ethereum.org/ru/developers/docs/nodes-and-clients/run-a-node/#spinning-up-node.

If you have 32 ETH but running a validator node seems too complex, enable solo staking. You will earn only slightly less than a validator without worrying about the infrastructure. A detailed solo staking guide is available on the official project website: https://ethereum.org/ru/staking/solo.

PoS “Mining” Services

If running a validator node isn’t an option, pooled staking is available through exchanges like Binance.  A detailed guide is available in a separate review on our site.

As of now, more than 14.8 million ETH are staked, supported by over 437,000 validators. Stakers earn passive income and receive wrapped tokens representing their locked ETH, which can be traded or sold – though redeeming the original ETH then becomes impossible.

Besides Binance, there are other services that support pooled ETH staking. Each pool and the tools or smart contracts they use were created by different teams, each with its own risks and benefits. There is even a community called EthStaker, where anyone can learn about Ethereum staking and take part in discussions. Detailed information about pooled staking and links to EthStaker community pages on social networks are available on the official project website: https://ethereum.org/ru/staking/pools.

NFTs on ETH

Non-fungible tokens (NFTs) also play a vital role in Ethereum’s ecosystem. They serve as digital certificates of ownership for both physical and virtual assets, bridging the gap between real-world property and blockchain verification.

Most existing NFTs are created on Ethereum under the ERC-721 and ERC-1155 standards. In addition, a new standard, EIP-2309, has been developed to allow minting any number of tokens in a single transaction.

What You Can Buy with Ethereum

Ethereum is primarily intended to power smart contracts, but it can also be used as a means of payment. See the list of stores that accept cryptocurrency at https://cryptwerk.com/pay-with/eth. And of course, you can sell ether for traditional money on a trading platform or cryptocurrency exchange.

How to Buy Ethereum

If you don’t want to obtain cryptocurrency yourself, you can buy ETH for fiat on exchanges such as:

  • Binance
  • Exmo
  • Bitfinex
  • Kraken
  • Coinbase

You can buy or sell ETH for dollars, or other cryptocurrencies on Binance. The exchange provides several ways to purchase ether:

  • Instant exchange of digital tokens and fiat
  • Spot market, where you can place market and limit orders
  • P2P service for buying ETH and other cryptocurrencies directly from token holders

The advantages of trading on an exchange are reliability and low fees.

Many other trading platforms also support the BTC/ETH pair. Cryptocurrency exchanges require registration, and for transactions with traditional money they also require account verification. You provide the exchange administration with copies of bank statements and documents confirming your identity and place of residence, and then wait for the review. Online exchangers allow you to remain anonymous but charge higher fees, and rates can vary significantly across sites. To avoid losing money, use only reputable online services.

How to Store Coins Properly

The golden rule for securing your crypto remains unchanged: never store your assets long-term on an exchange. To keep your digital assets fully secure, you must protect the secret keys to your wallet from malicious actors. What is a private key?

Like other blockchain projects, Ethereum uses asymmetric cryptography to create combinations of digits and Latin letters that provide access to your share of virtual assets. Ethereum generates a private key (for signing transactions) and a public key – your wallet address – which always starts with “0x.” You can safely share your address for receiving funds, but your private key must remain secret at all times.

The most popular wallet for storing ether is MyEtherWallet. It does not require downloading the blockchain to a hard drive, is simple to use, and is quite reliable – especially if you sync it with a Trezor or Ledger Nano X hardware wallet. Hardware wallets are devices resembling a USB flash drive with a mini display, designed for the secure storage of your private keys.

An excellent option for storing ETH and other cryptocurrencies is the SafePal S1 hardware wallet developed with support from the Binance exchange. Official website: https://www.safepal.com.

Never store private keys electronically on ordinary USB sticks, and especially not on PC hard drives. If anyone asks you to share your private key supposedly to send money to your address, never do it. Don’t brag on forums about your wallet balance and don’t disclose your storage method. Download and install software for working with digital assets only from trusted sources. That’s essentially all you need to know for safely storing Ethereum.

Conclusion

As one of the platform’s leaders, Vitalik Buterin, said:

“The Ethereum blockchain performs 15 transfers per second, but it should do 100,000. The development team has two main scaling strategies – layer one and layer two. To speed up transaction processing, sharding will be used; its meaning lies in distributing transactions across different network nodes selected at random. This technique will speed up the blockchain by 1,000 times or more.”

With Ethereum’s shift to PoS, users expect faster transactions, lower fees, and improved scalability. If the development team achieves these goals, Ethereum’s dominance will only grow – pushing blockchain technology and digital finance further into the global economy.

The future belongs to the cyber-economy, and the currency of that future isn’t paper or metal – it’s mathematics.
