What is Ethereum?

As an analyst, I would describe Ethereum as a globally distributed software platform, underpinned by blockchain technology, enabling trustless interactions. Essentially, it functions as a network of computers adhering to the Ethereum protocol, which empowers developers to construct decentralized applications (dapps) upon this robust infrastructure.

As a analyst, I would rephrase it this way: Unlike my focus being solely on financial transactions with Bitcoin, Ethereum’s designers envisioned a more expansive use for blockchain technology. They aimed to create a decentralized applications platform instead. Ethereum was among the pioneers in recognizing the full potential of blockchain beyond just facilitating secure virtual payments.

Ethereum was built as a decentralized computing platform, leading to the emergence of decentralized finance. Unlike Bitcoin, Ethereum’s capabilities extend beyond just making payments through Ether.

Ethereum basics

As a cryptocurrency analyst, I’ll delve into the fundamentals of Ethereum in this part. We’ll trace its origins and discuss how it distinguishes itself from Bitcoin, the pioneering digital currency that paved the way for its existence.

History of Ethereum

In 2013, the idea for Ethereum was born out of the mind of Russian-Canadian programmer Vitalik Buterin. He penned a whitepaper detailing Ethereum as a decentralized system engineered to execute smart contracts.

As a crypto investor, I can tell you that my long-awaited vision came to life on July 30, 2015. That was the day Ethereum’s first public version, named Frontier, officially went live after numerous months of dedicated work. This groundbreaking project, which I had supported through an Initial Coin Offering (ICO), raised an impressive $18 million to fuel its development.

Gavin Wood, Charles Hoskinson, Anthony Di Iorio, and Joseph Lubin were key contributors to the project’s progress.

As a researcher studying the blockchain technology behind Ethereum, I can tell you that this platform has experienced significant advancements through various hard forks over its existence. These forks represent essential updates to the network, introducing novel functionalities, enhancing security, and rectifying any existing problems.

In 2016, the first significant split in the Ethereum blockchain occurred due to an attack on its decentralized autonomous organization (DAO), resulting in the theft of approximately 3.6 million ETH. This incident sparked a contentious response, as developers opted for a hard fork – essentially rewriting the past transactions on the blockchain – giving birth to two distinct versions: Ethereum and Ethereum Classic (ETC).

Other vital updates and hard forks in Ethereum’s history include the following:

    Byzantium (Oct. 16, 2017): It reduced mining rewards from 5 to 3 ETH, delayed the difficulty bomb, enabled non-state-changing contract calls, and added cryptographic methods for L2 scaling.
    Constantinople (Feb. 28, 2019): This update also further reduced mining rewards from 3 to 2 ETH and helped optimize gas costs.
    Istanbul (Dec. 8, 2019): This update optimized gas costs, improved DoS attack resilience, enhanced performance for layer-2 (L2) solutions and enabled Ethereum-Zcash interoperability.
    Beacon Chain Genesis (Dec. 1, 2020): Marked the beginning of Ethereum 2.0 by starting the Beacon Chain after meeting the required 32 ETH deposits.
    Berlin (April 15, 2021): This update optimized gas costs and increased support for multiple transaction types.
    London (Aug. 5, 2021): It introduced EIP-1559, reforming the transaction fee market with variable-sized blocks, and making gas fees more predictable.
    Paris (Sept. 15, 2022): Popularly referred to as The Merge, this upgrade transitioned Ethereum from proof-of-work to proof-of-stake, significantly changing the network’s consensus mechanism.
    Shanghai-Capella (April 12, 2023): This upgrade enabled staking withdrawals on Ethereum’s execution layer and introduced automatic account sweeping for rewards and withdrawals.
    Cancun-Deneb (March 13, 2024): Also known as Dencun, this update introduced EIP-4844 (proto-danksharding) to lower data storage costs for L2 rollups, enhancing scalability and reducing transaction fees. It also included pre-generated exit messages for stakers and capped the validator join rate to limit the issuance of ETH.

Ethereum vs. Bitcoin

It’s crucial to understand that Ethereum and Bitcoin, being the top cryptocurrencies, have different objectives and ideas behind their creation when evaluating their comparisons.

As an analyst, I would describe Bitcoin as follows: I analyze Bitcoin as a groundbreaking digital currency that serves as a decentralized alternative to conventional fiat currencies. With Bitcoin, transactions can be carried out directly between individuals without the need for intermediaries such as banks or governments. This digital asset primarily functions as a store of value, which is why it is often referred to as “digital gold.”

Ethereum, on the other hand, was designed to expand beyond Bitcoin’s financial use case. 

As a researcher exploring the world of blockchain technology, I’ve come across an intriguing development: the implementation of smart contracts. These self-executing codes allow for seamless transactions and agreements between anonymous parties, without the need for intermediaries. This groundbreaking innovation paved the way for the creation of decentralized applications on Ethereum. The blockchain’s native cryptocurrency, Ether, plays a dual role in this ecosystem. It functions both as a digital currency and the essential fuel that powers the execution of smart contracts.

Bitcoin and Ethereum are two popular digital currencies that employ blockchain technology. However, they differ in their consensus mechanisms. Bitcoin relies on the proof-of-work protocol, where miners work on intricate mathematical problems to validate transactions and add new blocks to the blockchain. In contrast, Ethereum initially followed this method but has subsequently switched to proof of stake. Proof of stake is more energy-efficient as it doesn’t require extensive computational power for validation, thereby enabling swifter transaction processing times.

Bitcoin boasts a larger market value than Ethereum, with Bitcoin currently assessed at over $1.3 trillion against Ethereum’s $452 billion. Nevertheless, when it comes to transaction volume, Ethereum consistently handles over one million transactions per day, whereas Bitcoin processes around 500,000 daily transactions based on YCharts data.

Key components

What makes Ethereum tick are some essential features. Among them is its own digital currency, Ether, and a contract system that automates deals. Additionally, it supports decentralized programs operating on its blockchain framework.

Ethereum relies on the Ethereum Virtual Machine (EVM) to run scripts and facilitate decentralized computation. In unison, these elements serve as the foundation for Ethereum’s groundbreaking technology ecosystem, shaping the future of decentralized innovation.

Ethereum blockchain

The Ethereum blockchain represents a decentralized, digital record-keeping system that documents all transactions occurring on the network. This ledger is kept up-to-date by a network of computers (nodes) whose primary role is to authenticate and execute transactions in adherence with the Ethereum protocol.

The Ethereum blockchain is built on a chain of connected blocks in its fundamental structure. Each block holds a record of transactions, which can involve the transfer of value, the activation of smart contracts, or the introduction of decentralized applications (dApps).

Ether (ETH)

For those inquisitive about the essence of Ether, it represents the native digital currency of the Ethereum network. In contrast to Bitcoin, which essentially functions as a digital alternative to gold, Ether serves multiple purposes. It acts as the essential energy source for the network, indispensable for the processing of transactions and the operation of applications on the Ethereum platform.

As a researcher studying the functionality of blockchain networks, I can explain that each transaction and smart contract executed on the system necessitates a certain amount of computational power. In return, users are required to pay gas fees in Ethereum (ETH) as an incentive for validators to process these requests efficiently and maintain the network’s security and seamless operation.

As a crypto investor, I’ve observed that the amount of gas needed for a transaction depends on its intricacy. Moreover, gas fees are subject to change based on the current network congestion levels.

Smart contracts

One key aspect of Ethereum is its capability to host smart contracts. Smart contracts signify agreements whose terms are embedded within the code itself. Once specific prerequisites are fulfilled, these contracts will independently carry out and enforce the stipulated conditions.

As a contract analyst, I can tell you that I work with smart contracts designed to operate on the Ethereum Virtual Machine (EVM). This decentralized computing platform guarantees consistent script execution throughout the network, making it an ideal choice for deploying intricate dapps and automating transactions. The EVM’s beauty lies in its ability to enable developers to carry out these tasks without relying on intermediaries.

Decentralized applications (dapps)

Dapps, or decentralized applications, function differently than typical apps as they are built on Ethereum’s decentralized structure instead of relying on centralized servers. This setup provides several advantages: increased security due to the distributed nature of blockchain, transparency by storing data publicly and permanently, and immunity to censorship since there is no single entity controlling the application.

Developers have the flexibility to create various types of applications, or dapps, on Ethereum platform. Ranging from financial tools and games to complex systems like supply chain management and social networks, these applications leverage the strengths of Ethereum’s intelligent contract technology and decentralized framework.

Ethereum 2.0

As an analyst, I would describe Ethereum 2.0 as my perspective on a major enhancement to the Ethereum blockchain. This upgrade is designed to address key concerns related to scalability, security, and sustainability. By tackling these limitations head-on, we’re setting the foundation for a more robust and efficient decentralized ecosystem in the future.

The key aspects of this system involved transitioning from Proof of Work (PoW) to Proof of Stake (PoS) as its consensus mechanism. This change resulted in a replacement of miners with validators.

As a researcher studying the Ethereum blockchain, I would describe it this way: In December 2020, I observed the introduction of Proof of Stake (PoS) into the Ethereum ecosystem through the Beacon Chain. This new chain ran in parallel to the original Ethereum PoW chain. My role as an observer involved witnessing how the Beacon Chain coordinated the network of stakers and managed the consensus mechanism. Its significance lies in its preparatory function for the eventual transition of the Ethereum network into Ethereum 2.0.

In September 2022, the Ethereum main network and the Beacon Chain were united in an event called The Merge. This significant transition moved the entire Ethereum network from Proof of Work (PoW) to Proof of Stake (PoS). Moreover, The Merge preserved Ethereum’s history and data while introducing the enhanced capabilities of Ethereum 2.0.

Use cases of Ethereum

As a crypto investor and user of Ethereum, I can tell you that this digital currency serves as the lifeblood of the Ethereum network, which functions as a decentralized financial system open to all. Beyond enabling transactions between parties, Ether offers various applications within this ecosystem. For instance:

  • Gas fees: Ether facilitates payments of transaction fees, commonly referred to as gas and the computational resources required for developing and deploying smart contracts and Ethereum apps such as dapps. 
  • Powering decentralized applications: Ether is required to power decentralized apps built on Ethereum. The token facilitates staking, yield farming, and governance through voting.
  • Investments: You can earn interest by staking Ether and other Ethereum-based tokens on crypto-staking platforms. 

Regarding the blockchain itself, it has proven to be versatile with applications going beyond just transactions. A notable example is decentralized finance (DEFi), where Ethereum serves as the foundation for a flourishing financial sector offering services such as lending, borrowing, trading, and accruing interest, all without the involvement of intermediaries.

As a analyst, I would put it this way: I observe that Ethereum serves as the leading infrastructure for non-fungible tokens (NFTs). NFTs are distinct digital assets embodying possession of unique items such as artworks, music tracks, virtual properties, and creative pieces.

The Ethereum blockchain brings advantages to fields like supply chain management. By allowing for the tracking of a product’s origin and journey, it increases transparency and streamlines processes, ultimately decreasing opportunities for fraud.

Furthermore, Ethereum offers solutions in the realm of identity management. Users have the ability to manage their digital identities in a secure manner, issuing verified credentials only when required, all while maintaining privacy and security.

Future of Ethereum

As Ethereum progresses and develops, it holds great potential for the future and may significantly impact multiple industries through its innovative technology.

The move to Ethereum 2.0 signifies a major advancement for Ethereum, improving its capacity, security, and longevity. Furthermore, as Ethereum evolves from proof-of-work to proof-of-stake consensus mechanism, it becomes more energy-efficient and prepared to process larger volumes of transactions.

With this update, we’ll create a stronger and more productive decentralized infrastructure, opening up fresh opportunities in the realm of decentralized finance, NFTs, supply chain administration, real-world asset digitization, web3 gaming, and identity verification, among other areas.

With Ethereum’s growing abilities and its technology ecosystem becoming more established, it may significantly influence the development of decentralized technology, providing an effective foundation for various applications.
