Ethereum is no longer just a name echoed in the world of digital currencies; it has become the beating heart of the decentralized finance (DeFi) revolution, non-fungible tokens (NFTs), and the future of the internet (Web 3.0). Over the past few years, the Ethereum network has undergone a series of transformative changes that have redefined its capabilities and position in the digital landscape.
The historic transition: from 'Proof of Work' to 'Proof of Stake'
The most significant and impactful shift was 'The Merge,' which took place in September 2022. This bold step completely transitioned Ethereum from an energy-intensive 'Proof of Work' mechanism to a more efficient 'Proof of Stake' mechanism. This was not just a technical change; it was a radical transformation with enormous environmental and economic implications:
* Energy Efficiency: The network's energy consumption has decreased by nearly 99%, making Ethereum one of the most environmentally sustainable blockchain networks.
* Deflationary model: Thanks to the mechanism of burning a portion of transaction fees (EIP-1559), Ethereum has become a partially deflationary asset. This means that a portion of Ether is pulled from circulation with each transaction, reducing the total supply over time and enhancing its potential value.
* Staking: The transition to a proof-of-stake mechanism has allowed users to 'stake' their Ether to support network security and validate transactions, earning rewards for doing so, thereby attracting a broader base of investors.
Ongoing upgrades: towards a more efficient and scalable future
The evolution did not stop at 'The Merge'. The Ethereum team and community continue to work on an ambitious roadmap to improve the network, with highlights including:
* Dencun Upgrade (March 2024): This upgrade played a pivotal role in reducing transaction costs on Layer 2 solutions like Arbitrum and Optimism. By introducing 'blobs' for data storage, these solutions became more efficient, enhancing the user experience and encouraging wider adoption of decentralized applications. This represents a crucial step towards Ethereum's goal of becoming a widely scalable network.
* Pectra Upgrade (expected in late 2024 or early 2025): The Pectra upgrade (which combines improvements from 'Prague' for the execution layer and 'Electra' for the consensus layer) is another crucial step. This upgrade will bring many important features, including:
* Account Abstraction: This feature will enable wallets to function as smart contracts, providing greater flexibility for users, such as the ability to pay transaction fees in non-Ether currencies (like USDC) or even allowing third parties to sponsor fees. This will greatly enhance the experience for new users and make interacting with the network smoother.
* Increasing the validator staking limit: Pectra will raise the maximum stakable Ether per validator from 32 ETH to 2048 ETH, allowing larger validators to pool their stakes and reduce the overall number of validators without decreasing the staked Ether. This reduces the network load and enhances the efficiency of the consensus layer.
* Scalability improvements: Pectra will continue to pave the way for further scalability enhancements, including a focus on 'Verkle trees' that will reduce the size of Ethereum data in the long term.
The outlook: Building the 'global internet'
These ongoing developments aim to achieve Ethereum's ultimate vision known as 'Serenity' or 'Ethereum 2.0', which aims to build a network capable of processing hundreds of thousands of transactions per second through mechanisms like 'Sharding'. This will make Ethereum powerful enough to host the next generation of decentralized applications on a global scale, enhancing its role as the backbone of the decentralized internet.
Ethereum is not just a digital currency; it is an ambitious project that continuously evolves, aiming to reshape how we interact with technology and money. With each new upgrade, Ethereum moves one step closer to realizing its vision of being the 'global computer' that operates efficiently, securely, and with complete decentralization. Following these changes is not just about keeping up with the price of the currency, but understanding the direction it is heading.
Our digital future.
