The Ethereum blockchain has seen numerous events over the years, ranging from minor ones, such as minor updates to Ethereum 1.0, to significant ones that have impacted its core ideas, such as the network's transition from the PoW consensus mechanism (Proof-of-Work, mining) to PoS (Proof-of-Stake), in Ethereum 2.0. But how much is Ethereum 2.0 superior to Ethereum 1.0, and what are the primary distinctions between the two?
The Ethereum 1.0 and 2.0 versions of the network, their primary distinctions, and the network's future development will all be covered in this article.
Ethereum 1.0, also known as the Ethereum mainnet, is a blockchain network version that uses the PoW protocol and permits ETH token mining. The network's existence since the launch of Ethereum in 2015 is generally represented by this version, which includes all updates and hard forks up until the major upgrade on September 15, 2022, when the blockchain coins changed from a PoW consensus mechanism to a PoS one. Staking, the process of keeping Ethereum tokens in a cryptocurrency wallet to support all blockchain processes, is a component of proof of stake (PoS) that requires transaction verification. As a result, the network's underlying enhanced efficiency, security, and scalability were all dramatically altered.
Throughout Ethereum 1.0's existence, the network underwent numerous hard forks and various upgrades, most of which were focused on boosting Ethereum transaction throughput, cutting commission costs, and bolstering security to thwart hacking attacks, which have occasionally happened in the coin's history. After failed attempts to scale the network to meet technical regulations regarding transaction speed and security, Ethereum 1.0 was created with the dual goals of testing the PoW consensus mechanism and determining whether it could transition to another consensus mechanism (PoS). For a detailed comparison of Ethereum and Bitcoin’s technological differences and evolution, refer to a guide about Bitcoin vs. Ethereum.
The Ethereum 2.0 network, known as "Merge," is a significant improvement of its core ideas with an emphasis on increasing scalability. It is the first time in the history of the cryptocurrency industry that the functioning blockchain has moved from using the Proof-of-Work algorithm to the Proof-of-Stake algorithm. Miners used to align new blocks on the Ethereum blockchain, but with the Merge, digital coin holders are rewarded for ensuring the system's functionality.
A gradual transition of the network from one consensus mechanism to another is planned as part of the Ethereum 2.0 release. Beacon Chain, Merge, and Sharding are the three primary steps in the roadmap.

The first cryptocurrency network in history to undergo such an important change in its fundamentals was the Ethereum Coin Network. Blockchain was given new life and the chance to create new technology solutions based on the new "stuffing" after the merger, which fundamentally altered the landscape of the industry. In any case, the network has improved greatly as a result of the improvement. The main distinctions between Ethereum 1.0 and Ethereum 2.0 updates in terms of blockchain, security, and other factors will be examined here.
The consensus protocol is the key distinction between Ethereum 1.0 and Ethereum 2.0. In Ethereum 1.0, transactions and blockchain data were validated through the Proof of Work (PoW) mechanism, which required miners to solve complex mathematical puzzles in order to add new blocks to the blockchain. This process, while secure, is energy-intensive and contributes to high transaction costs and slower processing times. If you’re interested in understanding the broader principles behind consensus mechanisms like PoW and PoS, this beginner's guide to consensus may help clarify.
In contrast, Ethereum 2.0 introduces Proof of Stake (PoS), a more energy-efficient consensus mechanism that rewards participants for holding and staking ETH tokens, which are used as network maintenance tools. In PoS, participants lock up a certain amount of ETH to become validators, who are responsible for verifying transactions and adding new blocks to the chain. The more ETH a participant stakes, the higher their chances of being selected to validate transactions, thus securing the network.
In order to distinguish between the two updates in this criterion, one must first comprehend that the blockchain is a series of blocks that are validated through the use of mining equipment's computing power. Ethereum 1.0 is a traditional blockchain network paradigm in which all transactions are encoded in a continuous, sequential chain of blocks. With its division into tiny units known as shard chains, Ethereum 2.0 is a new model for how the blockchain system functions. This enables transactions to be processed in parallel chains as opposed to sequential ones, effectively tackling scalability issues as explored in detail in this blog on how blockchain is revolutionizing the fintech industry.
With Ethereum 1.0, a major player controls all network activity during mining by possessing more than 50% of the network's computational power, which is in accordance with traditional PoW blockchain principles. This might potentially result in vulnerabilities like 51% of assaults. This PoW mechanism characteristic has raised serious concerns throughout the coin's existence and presented a security risk.
In Ethereum 2.0, because miners no longer control the blockchain, mining power is replaced by validators, which decentralizes control. With the new consensus protocol, the network needs roughly 16,000 validators, which makes it less vulnerable to manipulation, more decentralized, and safe.
One of the most essential steps of network performance is transaction speed. There were delays and congestion in Ethereum 1.0 because the network could only handle roughly 30 transactions per second.
According to official numbers, Ethereum 2.0 can process 100,000 transactions per second. The addition of shard chains allowed for this rise. Furthermore, significantly faster transaction speeds will be possible in the future, both inside the Ethereum ecosystem and with third-party networks, by implementing second-tier solutions like rollups and different side-chains.
Rollups work by bundling multiple transactions together off-chain and then submitting a single, consolidated transaction to the main Ethereum chain. This approach reduces the amount of data processed directly on Ethereum, improving both speed and cost-efficiency without compromising security.
Sharding is the process of dividing a network into several parts that can function somewhat independently. The amount of transactions that may be handled can be greatly expanded by segmenting the blockchain into several parts.
The Ethereum 1.0 POW Consensus required the usage of mining equipment, which is a type of computer hardware that has a video card, or a mining farm in order to conduct the mining process. A mining farm is an intricate network of linked devices that use strong video cards to process vast amounts of data. Numerous adverse effects of mining include high power consumption, environmental hazards, expensive equipment, and inadequate security.
By using PoS consensus, the Ethereum 2.0 network does away with the need for miners in mining new blocks; instead, validators verify transactions.
As opposed to PoW, the new model doesn't require the usage of specialized, sophisticated, and high-tech equipment, which helps to prevent issues with excessive energy consumption. Staking makes mining new coins easier by allowing users to hold their currency inside the blockchain and receive benefits in the form of network commissions.
Ethereum 1.0, while groundbreaking, is limited in its ability to process transactions quickly. It can only handle a relatively small number of transactions per second (TPS), which often leads to network congestion and high gas fees, especially during periods of high demand.
Ethereum 2.0, however, introduces a revolutionary upgrade with the implementation of shard chains. Sharding breaks the network into smaller, more manageable parts, allowing Ethereum to process multiple transactions in parallel rather than sequentially. This shift dramatically increases the network's capacity and scalability, enabling it to handle far more transactions at once.
With Ethereum 1.0, processing a high volume of transactions requires paying a hefty gas price. With the release of Ethereum 2.0, namely the "London" update, numerous fixes were made to improve the predictability of Ethereum transactions for users by updating the commission mechanism. For a deeper understanding of how these gas fees impact transactions, you can refer to this guide on crypto gas fees.
Ethereum gas fees—essentially the cost of executing transactions and running smart contracts—are expected to decrease significantly with Ethereum 2.0. Lower transaction fees make the network more affordable for both everyday users and businesses, enhancing its accessibility and usability. This, in turn, could drive greater adoption of Ethereum, attracting more decentralized applications (dApps), developers, and users to the platform.

Since the Ethereum Shanghai upgrade, mining has been replaced by staking on Ethereum 2.0, where users lock up ETH to validate transactions and earn rewards. This shift lowers transaction costs, improves security, and allows users to earn passive income. Rollups, including optimistic and validity rollups, are key to Ethereum’s scalability, offering faster and cheaper transactions. Ethereum’s roadmap now supports rollups at the blockchain level, aiming for greater scalability and efficiency by moving complex decentralized apps to Layer 2 (L2), while Layer 1 (L1) becomes a secure settlement layer. For businesses interested in adopting crypto, Ethereum’s evolving model offers promising prospects, especially in light of why small businesses should consider accepting cryptocurrencies by 2025.
Ethereum is continuously evolving, with ongoing updates to tools and protocols. While full scalability and lower fees won’t come immediately, the network’s shift to Proof of Stake (PoS) and staking rewards is a significant step toward a more decentralized and efficient future. Validators—stakers who lock ETH in pools or exchanges—play a crucial role in securing the network, replacing miners, and ensuring Ethereum’s long-term growth. Additionally, for users looking to manage transaction costs, there are top cryptocurrencies with low transaction fees that could be valuable to explore.
In Ethereum 2.0, validators (or stakers) replace miners, securing the network by verifying transactions and creating new blocks. To become a validator, participants must stake 32 ETH. Stakers are more exposed to ETH's price fluctuations since they need to hold ETH in their wallets. Those unable to stake the full 32 ETH can join a staking pool, where funds are pooled together, and rewards are distributed based on contribution. For merchants and individuals interested in crypto payments, platforms like Maxelpay, recognized as a best crypto payment gateway for 2024, provide efficient solutions for handling these digital assets.
Validators are rewarded with ETH for their participation. However, Ethereum 2.0 has built-in security: any validator that acts maliciously or fails to perform their duties can be slashed (losing part of their staked ETH) and ejected from the network. For those exploring crypto exchanges, here are some of the best cryptocurrency exchanges for 2024 to consider, whether for staking, trading, or long-term investing.
This shift to Proof of Stake (PoS) makes Ethereum more energy-efficient and gives validators a crucial role in maintaining the network’s integrity and driving its future upgrades.
The Ethereum network is undergoing significant improvements and is on its way to becoming a universal platform for establishing new projects using smart contracts, which will hasten the development of the cryptocurrency field even more. With the adoption of a new consensus mechanism that includes Ethereum staking, the network will become more secure, efficient, and faster. This will help in the development of new ways for the financial industry and the world of crypto technologies to communicate.
