What Is Ethereum 2.0?

Previously referred to as Ethereum 2.0 or ETH 2.0, the term describes Ethereum's significant upgrade transitioning from a Proof of Work (PoW) consensus mechanism to a more efficient Proof of Stake (PoS) system. The name "Ethereum 2.0" was retired to avoid confusion and prevent scams involving fake ETH2 tokens. The Merge did not change Ethereum's ticker symbol; it remains ETH.

Ethereum vs. Ethereum 2.0: Key Differences

For most users, the Merge caused no immediate changes in how Ethereum operates. ETH holders retained their tokens without any action required, and transaction functionalities remained the same. However, the underlying blockchain underwent a revolutionary shift:

1. Consensus Mechanism: Ethereum moved from PoW, which relies on energy-intensive mining, to PoS, which uses validators staking ETH to validate transactions.
2. Energy Efficiency: PoS drastically reduced Ethereum's energy consumption by over 99.95%, according to the Crypto Carbon Ratings Institute (CCRI).
3. Scalability Enhancements: While the Merge itself didn’t lower transaction fees, it laid the groundwork for future scalability through sharding.

What Is the Ethereum Merge?

The Ethereum Merge refers to the integration of Ethereum's existing mainnet with the Beacon Chain, the new PoS network. It marked the culmination of years of development, transitioning Ethereum into a sustainable and scalable blockchain ecosystem.

Key Phases of the Merge:

1. The Beacon Chain:
   Launched on December 1, 2020, this parallel network introduced the PoS mechanism, enabling validators to stake 32 ETH for transaction validation. It ran alongside Ethereum’s PoW network until the Merge.
2. The Merge Itself:
   The transition united Ethereum’s mainnet with the Beacon Chain, effectively phasing out mining. Leading up to this, multiple testnets (Ropsten, Sepolia, Goerli) were merged successfully to test the PoS infrastructure.
3. Sharding (Upcoming):
   Sharding, expected in 2024, will divide Ethereum’s dataset into smaller segments, improving transaction throughput and reducing gas fees. This mechanism will enhance scalability and allow Layer-2 solutions like zkSync to process transactions more efficiently.

Impacts of the Ethereum Merge

The Merge addressed Ethereum’s three main challenges: security, scalability, and sustainability.

1. Security

Validators are incentivized to act honestly, with penalties like slashing (loss of staked ETH) for malicious activity. These measures, combined with validator shuffling, enhance network security against coordinated attacks.

2. Scalability

With the Merge and upcoming sharding, Ethereum is set to process 20,000–100,000 transactions per second (TPS), a significant leap from its current 15–30 TPS.

3. Sustainability

The transition to PoS reduced Ethereum's energy consumption to near-negligible levels, alleviating environmental concerns. PoW, by comparison, required substantial computational power and energy to secure the network.

When Did the Ethereum Update Occur?

Originally slated for September 19, 2022, the Ethereum Merge was completed earlier than anticipated on September 15, 2022. This successful transition was a monumental achievement for Ethereum’s developers and community.

‍

What Are the Next Steps for Ethereum?

Ethereum’s roadmap includes several upgrades to enhance its scalability, efficiency, and functionality:

1. The Surge:
   Implements sharding for higher transaction throughput.
2. The Verge:
   Introduces Verkle Trees, a more efficient data structure for network validation.
3. The Purge:
   Reduces data storage requirements for validators, improving network efficiency.
4. The Splurge:
   Adds miscellaneous updates to ensure the blockchain remains functional and resilient.

The next major milestone, sharding, is projected for 2024, alongside continuous advancements like the Shanghai and Capella (Shapella) upgrades, which enabled ETH withdrawals starting April 12, 2023.

Ethereum Merge Frequently Asked Questions (FAQs)

‍

Do I need to convert ETH to ETH2?

No, ETH holders did not need to take any action during the Merge. Their assets were automatically transitioned.

Why stake ETH?

Staking secures the network while offering rewards for validators. Unlike PoW mining, PoS staking is accessible to users with basic hardware and internet connectivity.

What happened to staked ETH after the Merge?

Withdrawals of staked ETH were enabled through the Shanghai upgrade in April 2023.
