What is Ethereum? The Future of Decentralized Applications
Ethereum, the world’s second-largest cryptocurrency by market capitalization, was originally developed in 2013 and officially launched on July 30, 2015, by Vitalik Buterin. Unlike Bitcoin, the founders of the Ethereum network didn’t conceal their identity. Buterin, alongside his fellow co-founders, Gavin Wood, Charles Hoskinson, Anthony Di Iorio, and Joseph Lubin, all envisioned Ethereum as a platform capable of supporting decentralized applications (DApps) and smart contracts. The launch of the Ethereum network marked a significant milestone in the evolution of blockchain technology.The primary founder of Ethereum is Vitalik Buterin, a programmer and writer who first described the idea of Ethereum in a white paper titled “A Next-Generation Smart Contract and Decentralized Application Platform.” Buterin’s vision was to create a platform that could execute smart contracts and decentralized applications without the need for intermediaries. The other co-founders also played important roles in the development and launch of the Ethereum network. Gavin Wood designed the Ethereum Virtual Machine (EVM) and wrote the first implementation of the Ethereum protocol in C++. Ethereum initially used a Proof of Work (PoW) consensus mechanism, which had been inherited from Bitcoin, until September 2022, when Ethereum transitioned to a Proof of Stake (PoS) with the launch of the Merge upgrade. The Merge upgrade was aimed at improving the scalability, energy usage, and security of the Ethereum network.In the PoW phase, Ethereum miners used computational power to solve cryptographic puzzles and validate transactions, similar to Bitcoin. Miners were rewarded with Ether (ETH), the native cryptocurrency of the Ethereum network, for their efforts. The PoS mechanism, on the other hand, involves validators who are chosen to create new blocks based on the amount of Ether they hold and are willing to “stake” as collateral. This process is more energy-efficient and has a reduced tendency towards centralization.Initially, when Ethereum was using the PoW mechanism, it allowed around 15 transactions per second (TPS), which was significantly higher compared to Bitcoin’s 7 transactions per second but still lower compared to traditional payment systems. With the transition to PoS, Ethereum has laid the groundwork for potential future scalability improvements, primarily through layer 2 solutions and future upgrades like sharding, aiming to increase its transaction throughput.Mining on Ethereum during the PoW phase required very powerful hardware and high energy consumption. Miners competed to solve complicated mathematical problems, and whoever solved the problem first got to add a new block to the blockchain and will be rewarded in Ether. With the transition to PoS, the need for high-energy consumption mining has been eliminated, hence making Ethereum more green and sustainable.Ethereum has established numerous partnerships and has played a pivotal role in connecting traditional and blockchain finance to promote innovation across various industries, contributing to its growth and adoption.Ethereum has been one of the major centers for institutional partnerships, revealing a wide range of blockchain technology capabilities. BlackRock joined the world of Ethereum with spot ETFs, launching the BUIDL fund to boot. On the other hand, Fidelity contributes to the ecosystem with custody contributions and investment into Ethereum ETFs, while UBS pioneered a tokenized fund on Ethereum, and Citi explores Ethereum-powered financial products. Anchorage Digital, along with Liquid Collective, offers Ethereum liquid staking—a first for any OCC-chartered bank in the United States. Franklin Templeton also utilizes Ethereum’s scalability through Arbitrum, while Visa is building VTAP on Ethereum for tokenized assets. Microsoft is another big name that supports Ethereum through Azure, providing blockchain solutions, and JP Morgan developed Quorum, an Ethereum-based platform for enterprise use. Amazon Web Services has also made Ethereum the standard for its Amazon Managed Blockchain service. These engagements illustrate Ethereum has gone through many transformative developments that have further solidified its position as a leader in blockchain technology. First and foremost, “The Merge” in September 2022 finally saw Ethereum transition from Proof of Work to Proof of Stake, greatly reducing energy consumption and increasing scalability. EIP-1559, introduced with the London hard fork, reformed gas fees, making them more predictable and introducing a mechanism where ETH is burned, which can lead to deflationary characteristics depending on the balance between ETH issuance and burn rate. Layer 2 scaling solutions such as Optimism, Arbitrum, and Polygon have been paramount in processing transactions off the main chain to help fix congestion and reduce fees.The Dencun upgrade brought “proto-danksharding,” which is set to further improve scalability by increasing data availability for layer 2 rollups. The Ethereum Virtual Machine has also been continuously improved, supporting more complex smart contracts and decentralized applications, which has driven the growth of DeFi and NFT markets on platforms such as Uniswap, MakerDAO, and OpenSea. The Ethereum Improvement Proposals, like EIP-4844, continue to evolve the network, with future upgrades like Pralectra in the works, focusing on further scalability, security, and usability improvements. Altogether, these developments illustrate Ethereum’s commitment to innovation, making it one of the most versatile, developer-friendly platforms in the decentralized finance and digital art community.Recent developments in Ethereum indicate an increasing institutional interest and further evolution of the regulatory landscape. BlackRock, a traditional finance giant, showed interest in Ethereum, exploring Ethereum-based products like spot ETFs—a sign of mainstream adoption for the cryptocurrency. This interest from institutional whales is seen as a vote of confidence in Ethereum’ and its potential to make decentralized finance applications recognized.On the regulatory side, a Court of Appeals for the Fifth Circuit ruled that the sanctions imposed by the U.S. Department of the Treasury on Tornado Cash’s smart contracts were unlawful, as these contracts do not constitute “property” under existing sanction laws. This is seen as an important legal victory that may set the tone for where Ethereum goes in the near future, signaling a much friendlier regulatory environment toward decentralized technologies, potentially paving the way for more innovative applications on Ethereum.Ethereum’s price has fluctuated over the years. After reaching an all-time high of $4,891 in November 2021, Ethereum’s price has seen ups and downs with volatility mainly influenced by market sentiment, regulatory news, and macroeconomic factors. As of December 7, 2024, Ethereum is trading around $4,001, reflecting continued interest and investment in the cryptocurrency. With innovative technology and broad support from its community, Ethereum has positioned itself at the head of decentralized applications and smart contracts. As Ethereum also learns to operate under an increasingly clearer regulatory environment, complemented by ongoing innovation in new technological developments, its future is sealed in defining DeFi and digital assets for years to come.

FAQsQ1: How does Ethereum ensure the security of smart contracts?
A: Ethereum secures smart contracts through the Ethereum Virtual Machine (EVM), which executes code in a sandboxed environment. Additionally, security is enhanced by audits, formal verification tools, and community scrutiny. However, the responsibility also lies with developers to write secure code, as vulnerabilities in smart contracts can lead to exploits.
Q2: What are the different types of Ethereum Improvement Proposals (EIPs), and how do they affect the network?
A: EIPs are categorized into Standard (changes to protocol specifications), Core (changes to the core protocol), Networking (changes to network protocol), and Interface (changes to client API/RPC specifications). They can introduce new features, fix bugs, or optimize performance, directly impacting Ethereum’s functionality, security, and user experience.
Q3: How does Ethereum handle or prevent network congestion?
A: Ethereum mitigates network congestion through mechanisms like gas limits per block, EIP-1559 which makes transaction fees more predictable, and by encouraging the use of layer 2 scaling solutions like rollups (Optimism, Arbitrum) that process transactions off-chain and only settle on-chain.
Q4: What is the role of Ethereum’s gas limit, and how has it changed post-Merge?
A: The gas limit determines how much computational work can be done in a block. Post-Merge, while the fundamental concept remains, the mechanism for setting gas prices has changed with EIP-1559, introducing a base fee and burn mechanism, potentially making gas limits more dynamic in response to network demand.
Q5: How does Ethereum manage or plan to manage the environmental impact of its operations?
A: The shift to Proof of Stake (PoS) with The Merge significantly reduced Ethereum’s energy consumption by eliminating the need for mining. Ethereum also encourages green staking initiatives and continues to develop its network to be more energy-efficient through further upgrades.
Q6: What are the implications of Ethereum’s move to Proof of Stake for smaller investors?
A: PoS allows smaller investors to participate in network consensus by staking their ETH without needing expensive hardware. However, the 32 ETH requirement to run a validator node can still be prohibitive, leading to the rise of staking pools and liquid staking solutions where smaller amounts can be staked through intermediaries.
Q7: How does Ethereum address privacy concerns in its transactions?
A: Ethereum transactions are by default public, but privacy can be enhanced through solutions like zero-knowledge proofs (zk-SNARKs, zk-STARKs) used in some layer 2 solutions or privacy-focused applications like Tornado Cash (though with regulatory challenges). Future upgrades might introduce more privacy features at the protocol level.
