The need for improved scalability, security, and usability to support DeFi applications has driven research and development efforts, such as the transition to Proof-of-Stake (PoS) and the development of Layer-2 scaling solutions.¹⁰

In conclusion, DeFi has been a major catalyst for Ethereum’s growth and evolution.¹¹ It has increased the network’s utility, driven innovation, and attracted a large community of users and developers.¹² While challenges and risks remain, the DeFi movement has undoubtedly solidified Ethereum’s position as a leading blockchain platform and shaped its future trajectory.

Ethereum’s Evolution into two blocks in blockchain

Ethereum’s split into two blockchains, Ethereum (ETH) and Ethereum Classic (ETC), occurred due to a hard fork in 2016.¹ This hard fork was a direct response to a major security breach known as The DAO hack.²Here’s a breakdown of the events that led to the split:

1. The DAO and its Vulnerability:

The DAO (Decentralized Autonomous Organization) was a crowdfunding platform built on Ethereum that aimed to automate investment decisions through smart contracts.³

Unfortunately, The DAO’s smart contract contained a vulnerability that hackers exploited, resulting in the theft of 3.6 million ETH (worth approximately $50 million at the time).⁴

2. The Community’s Response:

The Ethereum community was faced with a dilemma: how to respond to the massive theft and the loss of funds.⁵Several options were debated, Do nothing: Accept the theft and move on. Soft fork: Implement a change to the Ethereum protocol that would “freeze” the stolen funds, preventing the hacker from accessing them. Hard fork: Create a new version of the Ethereum blockchain that would effectively reverse the transactions that led to the theft, returning the funds to their original owners.⁶

3. The Hard Fork Decision:

After much debate and controversy, the Ethereum community decided to implement a hard fork.⁷

This decision was not universally agreed upon, as some argued that it went against the principle of blockchain immutability.⁸

4. The Split:

The hard fork created a new version of the Ethereum blockchain, where the stolen funds were returned to their rightful owners.⁹ This new chain continued to be known as Ethereum (ETH).

However, a minority of users disagreed with the hard fork and continued to support the original, unaltered blockchain.¹⁰ This chain became known as Ethereum Classic (ETC).

5. The Aftermath:

The DAO hack and the subsequent hard fork had a significant impact on the Ethereum ecosystem.

It raised important questions about security, governance, and the immutability of blockchain transactions.

The split also led to the creation of two separate communities, each with its own vision for the future of Ethereum.

London upgrade and the Ethereum’s Evolution

The London upgrade was a significant update to the Ethereum network that went live on August 5th, 2021.¹ It introduced several changes, most notably EIP-1559, which aimed to improve the network’s transaction fee mechanism.²

Here’s a summary of the key aspects of the London upgrade:

EIP-1559: A New Fee Structure

Base Fee: EIP-1559 introduced a “base fee” for transactions, which is dynamically adjusted based on network congestion.³ When the network is busy, the base fee increases, and when it’s less busy, the base fee decreases.⁴ This helps to stabilize transaction fees and make them more predictable.⁵
Burning the Base Fee: A portion of the transaction fee, the base fee, is burned, effectively reducing the supply of Ether (ETH) over time.⁶ This mechanism was intended to potentially make ETH a deflationary asset.
Priority Fee (Tip): Users can also include a “priority fee” or “tip” to incentivize miners to prioritize their transactions.⁷ This allows users to pay extra to have their transactions processed faster.

Other EIPs Included in the London Upgrade:

EIP-3198: This EIP allows smart contracts to access the base fee of a block, which can be useful for various applications, such as gas price derivatives.⁸
EIP-3529: This EIP reduces gas refunds for certain operations, which helps to mitigate potential network congestion and security risks.⁹
EIP-3541: This EIP lays the groundwork for future Ethereum Virtual Machine (EVM) improvements by disallowing the deployment of new contracts with a specific byte sequence.¹⁰
EIP-3554: This EIP delays the “difficulty bomb,” a mechanism that makes it increasingly difficult to mine new blocks, encouraging a transition to Proof-of-Stake (PoS).¹¹

Impact of the London Upgrade:

More Predictable Fees: EIP-1559 has made transaction fees on Ethereum more predictable, reducing the volatility that users previously experienced.¹²
Potential Deflationary Pressure: The burning of the base fee has the potential to create deflationary pressure on ETH, although the actual impact on ETH’s supply is still debated.
Improved User Experience: The London upgrade has generally improved the user experience on Ethereum by making transactions more efficient and fees more predictable.¹³

Overall, the London upgrade was a significant step in the evolution of Ethereum, addressing some of the network’s key challenges and laying the groundwork for future improvements. It has helped to make Ethereum a more user-friendly and efficient platform for decentralized applications.

Forks of Ethereum

In the context of Ethereum, “forks” refer to changes or updates to the Ethereum blockchain.¹ There are two main types of forks:²

1. Soft Forks:

These are minor changes that are backward-compatible, meaning they don’t require all users to upgrade their software immediately.They are like small tweaks or adjustments to the existing rules of the blockchain.If users don’t upgrade, they can still participate in the network, but they might miss out on some new features.

2. Hard Forks:

These are more significant changes that are not backward-compatible. They essentially create a new version of the blockchain with different rules.All users need to upgrade their software to continue participating in the network after a hard fork.Sometimes, a hard fork can cause the blockchain to split into two separate chains: the original chain and the new chain. This happened with Ethereum and Ethereum Classic.

Why do Ethereum forks happen?

Ethereum forks are implemented for various reasons, including:

Upgrading the protocol: To improve the network’s performance, security, or functionality.
Fixing bugs: To address vulnerabilities or issues in the existing code.
Implementing new features: To introduce new capabilities or functionalities to the Ethereum network.
Responding to crises: To address unexpected events, such as hacks or exploits.

Examples of Ethereum forks:

The DAO Fork (2016): A controversial hard fork that resulted in the split of Ethereum into two chains: Ethereum (ETH) and Ethereum Classic (ETC).¹¹ This fork was in response to a major hack of a decentralized autonomous organization (DAO).
The Merge (2022): A significant upgrade that transitioned Ethereum from a Proof-of-Work (PoW) consensus mechanism to a Proof-of-Stake (PoS) mechanism.¹² This was a major change in how the Ethereum network operates.

In summary:

Ethereum forks are essential for the ongoing development and evolution of the Ethereum blockchain. They allow the network to adapt to new challenges, implement improvements, and remain at the forefront of blockchain technology.¹³
