Ethereum (ETH) stands as one of the most influential cryptocurrencies in the digital economy—second only to Bitcoin in market recognition. But unlike Bitcoin, which is often seen as digital gold, Ethereum functions as a decentralized computing platform that powers smart contracts, decentralized applications (dApps), and a vast ecosystem of financial innovation known as Decentralized Finance (DeFi). With over 122 million ETH tokens in circulation—more than ten times Bitcoin’s supply—Ethereum has cemented its role not just as a currency, but as foundational infrastructure for the future of web3.
Created in 2013 by Russian-Canadian programmer Vitalik Buterin and officially launched in 2015 from Switzerland, Ethereum was born out of frustration with centralized systems. A pivotal moment came when a change in the World of Warcraft game weakened Buterin’s character—an experience that led him to question the control centralized entities have over digital environments. This philosophy underpins Ethereum: a trustless, open-source network where applications run without interference from corporations or governments.
Today, Ethereum dominates more than half of the DeFi market, making its technological shifts and price movements highly influential across the crypto landscape. Events like the Ethereum Merge in September 2022 didn’t just alter the blockchain’s technical foundation—they reshaped environmental perceptions, investor sentiment, and the broader trajectory of blockchain sustainability.

The Ethereum Merge: From Proof-of-Work to Proof-of-Stake
For years, Ethereum operated on a Proof-of-Work (PoW) consensus mechanism—similar to Bitcoin—where miners used powerful computers to solve complex mathematical problems in exchange for newly minted ETH. While effective for security, PoW is notoriously energy-intensive.
In September 2022, Ethereum completed "The Merge," transitioning from PoW to Proof-of-Stake (PoS). Under this new model, validators "stake" their existing ETH to participate in transaction validation and earn rewards. This eliminated the need for energy-guzzling mining rigs and reduced Ethereum’s energy consumption by an estimated 99.95%.
Before the Merge, a single Ethereum transaction consumed energy equivalent to over 100,000 Visa transactions. Afterward, that number plummeted—making Ethereum not only more scalable but also more environmentally sustainable.
This shift placed Ethereum at the forefront of blockchain innovation. It quickly became the top cryptocurrency by staked value, surpassing long-standing PoS networks like Solana (SOL) and Cardano (ADA). The success of the Merge also boosted confidence in Ethereum’s ability to evolve, reinforcing its leadership in sectors like crypto lending, yield farming, and automated market makers within DeFi.
Market Impact and Network Activity Post-Merge
The Merge wasn’t just a technical upgrade—it had immediate economic and behavioral consequences.
While proponents celebrated the environmental benefits, some former miners were left behind. Many had invested heavily in GPU hardware designed for PoW mining. When Ethereum abandoned mining, these users faced obsolescence. Data shows a significant dumping of ETH by miner wallets in September 2022, likely due to profit-taking after years of holding mined tokens.
At the same time, daily transaction volume on the Ethereum blockchain surged to around 1.1 million transactions per day, reflecting strong network usage despite the transition.
Some miners migrated to alternative PoW blockchains such as Ethereum Classic (ETC) and Ravencoin (RVN), while others supported a fork called Ethereum PoW (ETHW). Although ETHW experienced short-term price volatility, it failed to gain lasting traction compared to the mainnet PoS chain.
Meanwhile, core metrics for Ethereum continued to strengthen:
- Daily active addresses remained robust, indicating sustained user engagement.
- Gas prices, while still variable during peak times, became more predictable post-upgrade.
- Staking participation grew rapidly, with major pools like Lido and Coinbase controlling significant portions of the staked supply.
These developments underscore Ethereum’s resilience and adaptability in a fast-moving digital asset landscape.

Frequently Asked Questions (FAQ)
Q: What is the difference between Ethereum and Bitcoin?
A: While both are major cryptocurrencies, Bitcoin serves primarily as a store of value ("digital gold"), whereas Ethereum is a programmable blockchain platform enabling smart contracts, dApps, and DeFi protocols.
Q: How did the Ethereum Merge affect energy use?
A: The Merge reduced Ethereum’s energy consumption by approximately 99.95%, making it one of the most eco-friendly blockchains relative to transaction volume.
Q: Can I still mine Ethereum?
A: No. After the switch to Proof-of-Stake in September 2022, traditional mining is no longer possible. Instead, users can participate through staking.
Q: What is staking in Ethereum?
A: Staking involves locking up ETH to help validate transactions on the network. In return, stakers receive rewards—similar to earning interest—in newly issued ETH.
Q: Is Ethereum more used than other blockchains in DeFi?
A: Yes. Ethereum continues to dominate the DeFi space, hosting over half of all total value locked (TVL) across decentralized finance platforms.
Q: What happened to miners after the Merge?
A: Many miners sold their ETH holdings or shifted to other PoW blockchains like Ethereum Classic or Ravencoin. Some supported forks such as ETHW, though adoption remained limited.
