What is an Ethereum Fork?

Before we discuss the Ethereum forks, let’s first understand what a fork is in the context of blockchain technology. A fork occurs when a blockchain splits into two separate chains, often due to a change in the underlying protocol or a disagreement within the community.

As explained by Ethereum ProAir, forks can be classified into two main categories: soft forks and hard forks. A soft fork is a backward-compatible upgrade to the protocol, meaning that nodes running the old software can still participate in the network. On the other hand, a hard fork is a radical change to the protocol that requires all nodes to upgrade to the new software to continue participating in the network.

Soft Fork:

Step 1: Proposal
A proposal is made to implement a new rule or upgrade to the Ethereum protocol.

Step 2: Consensus
A majority of nodes on the network agree to implement the proposal.

Step 3: Software Update
Nodes can optionally update their software to support the new rule.

Step 4: Compatibility
Nodes running the old software can still participate in the network and validate transactions.

Step 5: Gradual Adoption
More nodes gradually update to the new software, increasing the security and efficiency of the network.

Key Characteristics:

• Backward-compatible
• Optional software update
• Old nodes can still participate
• Gradual adoption

Hard Fork:

Step 1: Proposal
A proposal is made to implement a radical change to the Ethereum protocol.

Step 2: Consensus
A majority of nodes on the network agree to implement the proposal.

Step 3: Software Update
All nodes must update their software to support the new protocol.

Step 4: Incompatibility
Nodes running the old software can no longer participate in the network or validate transactions.

Step 5: Network Split
The network splits into two separate chains: one with the new protocol and one with the old protocol.

Key Characteristics:

• Not backward-compatible
• Mandatory software update
• Old nodes cannot participate
• Network split

Now, imagine if the Ethereum community were a group of adventurers exploring a vast cave system. Soft forks would be like adding a new passage to the cave that everyone can access, while hard forks would be like dynamiting a new tunnel that requires everyone to take a different route.

The DAO Hard Fork

One of the most significant hard forks in Ethereum’s history was the DAO hard fork, which occurred in 2016. The DAO (Decentralized Autonomous Organization) was a complex smart contract that raised over $150 million in a token sale. However, due to a vulnerability in the code, an attacker was able to drain a significant portion of the funds.

The Ethereum community was faced with a difficult decision: let the attacker keep the stolen funds or implement a hard fork to restore the funds to their original owners. After much debate, the community decided to proceed with the hard fork, resulting in the creation of two separate chains: Ethereum (ETH) and Ethereum Classic (ETC).

The DAO hard fork was a contentious event that sparked heated debates within the community. Some argued that the fork violated the immutability of the blockchain, while others believed that it was necessary to protect the integrity of the ecosystem.

Imagine if the DAO was a bank that got robbed and the Ethereum community was the police force. The hard fork was like the police deciding to rewind time and prevent the robbery from ever happening, while Ethereum Classic was like a parallel universe where the robbery still occurred.

The Constantinople Hard Fork

Fast forward to 2019 and the Ethereum community was gearing up for another major upgrade: the Constantinople hard fork. The Constantinople hard fork was a complex upgrade that included several Ethereum Improvement Proposals (EIPs) aimed at improving the platform’s performance and functionality.

One of the most significant changes introduced by Constantinople was the reduction of the block reward from 3 ETH to 2 ETH. This change was implemented to reduce the inflation rate of Ethereum and bring it closer to the long-term goal of a more sustainable economic model.

Another notable change was the introduction of the “create2” opcode, which allows for more efficient and secure deployment of smart contracts. This upgrade was particularly important for developers building decentralized applications (dApps) on the Ethereum platform.

Imagine if the Ethereum community were a team of engineers working on a complex machine. The Constantinople hard fork was like a major software update that improved the machine’s performance and added new features, but required everyone to shut down their machines and install the new software simultaneously.

The London Hard Fork

The London hard fork, which is scheduled for July 2021, is one of the most highly anticipated upgrades in Ethereum’s history. London hard fork includes several EIPs aimed at improving the platform’s fee market, user experience and scalability.

One of the most significant changes introduced by London is the “EIP-1559” proposal, which introduces a new fee market mechanism that includes a base fee that is burned with each transaction. This change is aimed at making the fee market more predictable and reducing the risk of users overpaying for gas fees.

Another notable change is the introduction of the “EIP-3554” proposal, which delays the difficulty bomb, a mechanism that increases the difficulty of mining Ethereum blocks over time. This change is aimed at giving developers more time to prepare for the transition to Ethereum 2.0, a major upgrade that will introduce proof-of-stake consensus and sharding to the platform.

Imagine if the Ethereum community were a team of musicians preparing for a grand concert. The London hard fork is like fine-tuning their instruments and rehearsing their performance to ensure a flawless show, while also making last-minute adjustments to the setlist to keep the audience engaged.

Hard Fork vs. Soft Fork

What is a Hard Fork?

A hard fork is a significant upgrade to a blockchain network that is not backward-compatible with the previous version. It results in a permanent divergence of the blockchain into two separate chains. Users must choose to upgrade to the new chain or continue on the old one.

What is a Soft Fork?

In contrast, a soft fork is a less disruptive upgrade that maintains backward compatibility with the existing network. It enforces new rules on the network, making them mandatory for all participants. Non-compliant nodes risk being forked off the network.

Real-World Examples of Hard and Soft Forks in Ethereum

Ethereum has implemented both hard and soft forks throughout it’s history. Constantinople and Istanbul are examples of hard forks, introducing significant changes to the network. Meanwhile, EIP-1559, part of the London upgrade, is an example of a soft fork, as it introduced new rules without causing a chain split.

Ethereum’s Recent Forks

Purpose and Objectives of Constantinople

Constantinople, implemented in February 2019, aimed to improve Ethereum’s performance and lower transaction costs. It introduced several Ethereum Improvement Proposals (EIPs), including EIP-1283 (Net Gas Metering), EIP-1014 (Skinny CREATE2) and EIP-1052 (EXTCODEHASH).

Key Features and Improvements Introduced

Constantinople addressed issues like gas inefficiency, smart contract execution and network security. It paved the way for future upgrades, demonstrating Ethereum’s commitment to continuous improvement.

Lessons from Istanbul and It’s Impact on Ethereum

The Istanbul hard fork, which occurred in December 2019, was another significant upgrade to the Ethereum platform. The Istanbul hard fork included several EIPs aimed at improving the platform’s security, performance and interoperability with other blockchains.

One of the most notable changes introduced by Istanbul was the addition of the “CHAINID” opcode, which allows smart contracts to identify the chain they are running on. This upgrade was particularly important for developers building cross-chain dApps that need to interact with multiple blockchains.

Another significant change was the reduction of the gas cost for certain opcodes, which made it cheaper to execute smart contracts on the Ethereum platform. This upgrade was aimed at improving the platform’s scalability and making it more accessible to developers and users.

Imagine if the Ethereum community were a team of adventurers exploring a vast wilderness. The Istanbul hard fork was like upgrading their equipment to make the journey faster, safer and more efficient, while also building bridges to connect with other teams of adventurers.

Istanbul, implemented in December 2019, built upon the foundation laid by Constantinople. It introduced further EIPs, such as EIP-1679 (Dynamic Incentive Scaling) and EIP-1884 (Repricing for trie-size-dependent opcodes), to enhance Ethereum’s performance and security. These upgrades have contributed to the network’s overall robustness.

The Eth2 Transition

Introduction to Ethereum 2.0 (Eth2)
