Ethereum, often abbreviated as ETH, is an open-source, blockchain-based platform that enables the creation and execution of smart contracts and decentralized applications (dApps). At its core, it provides a decentralized virtual machine known as the Ethereum Virtual Machine (EVM), which processes peer-to-peer contracts automatically.
To make this concept more relatable, think of Ethereum as a global, open-source version of an app store or an operating system. Just as developers can build various applications for iOS or Android, developers worldwide can build decentralized applications on Ethereum. These dApps range from games to complex financial instruments, all running on a decentralized network without a central authority.
The mastermind behind Ethereum is Vitalik Buterin, a programming prodigy often referred to as "V神" or "Vitalik" in the crypto community. His vision for Ethereum was inspired by Bitcoin but with a broader purpose. While Bitcoin was designed primarily as a digital alternative to traditional currency, Ethereum aims to provide a platform for running programmable applications, leading to significant differences in their value, functionality, and use cases.
What Is ETH and How Has Its Price Evolved?
Ether (ETH) is the native cryptocurrency of the Ethereum platform. It serves as both a governance token and a medium of payment within the network. However, its role extends beyond simple transactions—it acts as the fuel powering all operations on Ethereum.
Imagine Ethereum as a vast piece of digital land where users can build structures using smart contracts as building blocks. Every action on this land, whether it's executing a contract or storing data, requires payment in ETH to cover computational and storage costs.
ETH was first introduced in July 2014 through a crowdsale, with an initial price of approximately $0.308 per token. Over the years, its value has seen tremendous growth, reaching an all-time high of $4,369 in May 2021. This represents an increase of over 14,000 times from its initial offering. As of now, ETH's market capitalization stands at around $450 billion, making it the second-largest cryptocurrency after Bitcoin.
In terms of global asset rankings, ETH's market cap has surpassed that of platinum and even briefly exceeded major corporations like Visa and Johnson & Johnson during its peak. This highlights its growing importance in the financial landscape.
The Relationship Between DeFi and Ethereum
DeFi, short for Decentralized Finance, refers to a movement aimed at creating financial services built on blockchain technology. These services operate without traditional intermediaries like banks, offering greater transparency, efficiency, and accessibility. Ethereum is the leading platform for DeFi applications, hosting a vast ecosystem of projects.
As of recent data, the total value locked in Ethereum-based DeFi protocols exceeds $454 billion, underscoring its dominance in this space. But what exactly makes DeFi so compelling?
In traditional finance, activities such as lending, borrowing, or investing require intermediaries, which can lead to delays, opaque processes, and potential risks like data manipulation or loss. DeFi eliminates these intermediaries by relying on smart contracts—self-executing agreements coded on the blockchain. Once predefined conditions are met, transactions are automatically processed, reducing costs and increasing trust.
Ethereum's DeFi ecosystem encompasses various sectors, including lending, asset management, derivatives, decentralized exchanges (DEXs), and stablecoins. This diversity has attracted millions of users, driving innovation and growth. However, the surge in activity has also exposed limitations in Ethereum's current design, such as network congestion, slow transaction times, and high fees.
Understanding Ethereum 2.0
To address these challenges, the Ethereum community has been working on a major upgrade known as Ethereum 2.0 (or Eth2). This upgrade aims to enhance the network's scalability, security, and sustainability while reducing transaction costs. Key features of Ethereum 2.0 include a transition to Proof-of-Stake (PoS) consensus, the implementation of sharding technology, and the adoption of the eWASM virtual machine.
The shift from Proof-of-Work (PoW) to PoS is particularly significant. In PoS, validators are chosen to create new blocks and secure the network based on the amount of ETH they hold and are willing to "stake" as collateral. This method is more energy-efficient and allows for greater participation.
Sharding is another critical component. It involves splitting the Ethereum blockchain into smaller, interconnected pieces called shards. Each shard can process transactions and smart contracts independently, significantly increasing the network's capacity. To use an analogy, imagine upgrading from a single-lane road to a multi-lane highway—traffic flows smoother, and congestion is reduced.
For users interested in supporting the network, becoming a validator requires staking a minimum of 32 ETH. In return, validators earn rewards for their contributions. As of mid-May, over 4.42 million ETH had been staked in Ethereum 2.0 contracts, with an annualized return rate of approximately 7.5%. The enthusiasm for staking has far exceeded initial expectations, with the total staked amount being about 7.4 times the minimum required for launch.

Frequently Asked Questions
What is the difference between Ethereum and Bitcoin?
Bitcoin was designed primarily as a digital currency for peer-to-peer transactions and store of value. Ethereum, on the other hand, is a platform for building decentralized applications and executing smart contracts. While both use blockchain technology, their purposes and functionalities differ significantly.
How does staking work in Ethereum 2.0?
Staking involves locking up a certain amount of ETH (at least 32) to become a validator on the network. Validators are responsible for processing transactions and maintaining security. In return, they receive rewards based on their staked amount and participation.
What are the benefits of DeFi?
DeFi offers greater financial inclusivity, transparency, and efficiency by eliminating intermediaries. Users can access services like lending, borrowing, and trading directly through smart contracts, often with lower fees and faster processing times.
Will Ethereum 2.0 reduce transaction fees?
Yes, one of the primary goals of Ethereum 2.0 is to improve scalability through sharding and PoS. This should significantly increase transaction throughput and reduce fees, making the network more accessible for everyday users.
Is Ethereum 2.0 already live?
The upgrade to Ethereum 2.0 is being rolled out in phases. The first phase, which introduced the Beacon Chain and staking, is live. Subsequent phases, including sharding and full integration, are ongoing.
Can I unstake my ETH after staking?
Initially, staked ETH cannot be withdrawn until certain upgrades are completed. However, future updates will allow validators to unstake their funds, providing more flexibility.
Conclusion
If Bitcoin pioneered blockchain technology as a digital currency, Ethereum expanded its potential by enabling programmable applications and decentralized platforms. Ethereum 2.0 represents a transformative upgrade aimed at addressing current limitations while fostering greater innovation. As the network evolves, ETH's value is likely to grow alongside its expanding ecosystem, offering new opportunities for users and developers alike.
